    • Abstract: Salt stress conditions have been found to destroy the vital physiological process in plant where slower cell division and cell enlargement or both and limit mineral nutrient uptake with clearly nutritional imbalance. A greenhouse pot experiment was carried out at Agricultural Research Station, Mu’tah University, Jordan to evaluate growth responses and mineral composition of two strawberry cultivars to salt stress by different NaCl levels. Six NaCl levels (0, 25, 50, 75, 100 and 150 mM) and two strawberry cultivars, Camarosa and Albino, were used. Nutrient elements were added at the 0.5-strength Hoagland nutrient concentration. Distilled water supplemented with half strength Hoagland solution was used as control. Number of leaves and runners of both strawberry cultivars were significantly reduced by increasing NaCl level. Growth parameters (shoot, root and total dry weights and root: Shoot ratios) were significantly reduced with each increase in salinity level. Camarosa had higher value for all these parameters compared with Albino. Leaf chlorophyll content of both strawberry cultivars was significantly decreased when 25 mM NaCl or higher was applied. Regardless of NaCl level, Camarosa cultivar had significantly higher chlorophyll content compared with Albino. Elevated salinity level significantly increased leaf proline content of both cultivars. Albino leaves accumulated higher proline compared with Camarosa at salinized and non-salinized treatments. Both strawberry cultivars had significantly higher leaf and root Na and Cl contents under salinized conditions compared with non-salinized conditions. Each increase in NaCl level resulted in an increase in leaf and root Na and Cl contents of both cultivars. On contrast, leaf K content was decreased with salinity, root content of this mineral was significantly increased with salinity. It could be recommended to avoid growing ‘Camarosa’ and ‘Albino’ strawberry using irrigation water of 25 mM NaCl or more.
    • Abstract: This study was conducted to investigate the changes in nutrient level P as well as in the structural and functional groups upon the decomposition of Hemic and Sapric peat material due to application of lime and fertilizers. The peat materials were left to decompose for 8 weeks under laboratory incubation and samples were taken for the determination of extractable P at 1 week interval. At 8 weeks, samples were sent for FTIR and SEM analysis. Although both types of peat material exhibit similar patterns in the mineralization of phosphorus, however, the amount of extractable phosphorus between Hemic and Sapric during the decomposition process differed. Addition of fertilizer (T3) resulted in a significantly large increase in extractable P compared to T1 and T2 but the effect was temporal as the extractable P declined throughout the incubation period. Sapric material displayed more absorption bands from the FTIR spectral analysis compared to Hemic although there were few similarities between the bands produced. Application of fertilizer in T3 caused the peaks that were similar with other treatments became weaker and different functional groups were shown at lower frequencies. Images from SEM showed that addition of lime and fertilizers caused the collapsing and degradation of the plant cell structures in the organic materials of the peat justifying the process of decomposition had occurred. Hemic and Sapric peat material showed some similarities as well as differences in extractable P, plant cell structures and spectral bands upon the application of lime and fertilizers.
    • Abstract: Microwave-Assisted Extraction (MAE) kinetic in three temperatures was investigated for extraction of antioxidant phenolic compounds from Jatropha dioica, Flourensia cernua, Eucalyptus camaldulensis and Turnera diffusa which are plants of semiarid regions of Mexico. The two-site kinetic model and saturation simple equation were used to describe the experimental data. The fit of the data demonstrated that saturation simple equation was better and could explain the data with a slight loss of goodness of fit. The results showed that MAE optimum conditions were extraction temperature of 60°C and extraction time in the range from 1 to 6 min. The MAE was more efficient than the conventional Heat Reflux Extraction (HRE). Maximal antioxidant potential was observed in E. camaldulensis extracts. Interestingly differences in phenolic composition and antioxidant activity were observed in the extracts obtained by MAE and HRE for all plants used. Quercetin and catechin were found to be the predominant phenolic compounds. The MAE procedure resulted in suitable alternative to obtain bioactive phenolic compounds from semiarid plants due to this technology is higher efficient than conventional methods increasing yield in shorter times.
    • Abstract: The contents of total phenolics compounds and their phenolic constituents were quantified in organic and aqueous of four varieties (Zebdia, Sukkari, taimor and Hindi) of mango (Mangifera indica L.), seeds pulp and kernel, one varieties of pomegranate (Punica ranatum L., peel) and peanut (Arachis hypogaea L., Giza 6, shell) by-products. The antioxidant activities of all by products extracts were assessed by five antioxidant methods as well as by rancimate test. The total Phenolic content of aqueous and organic extracts of among all mango varieties, pomegranate and peanut shell showed the content values ranging from 71.06 to 124.18 mg/100g, 95.07 to 124.18 mg/100g and 41.64 to 71.06, respectively. Nineteen phenolic compounds were identified by High Performance Liquid Chromatography (HPLC) among all mango varieties, of which vanillic acid, benzoic acid and mangiferin were occurred in high amounts. The major phenolic compounds were detected in pomegranate and peanut shell were chlorogenic and gallic and caffeic (24.42%), respectively. All fruits by products were exhibited remarkable antioxidant activity, with various degrees in all tested methods. However, among all by-products extracts, organic extract had higher antioxidant than that aqueous extracts toward all antioxidant tested. Mango kernel peel and pomegranates showed high radical scavenging activity, which could be compared with the synthetic antioxidants Butylated Hydroxyanisol (BHA). However, all by-products extracts exhibited high inhibit effect against the lipid peroxidation of sunflower oil (at 100°C) as assessed by rancimat methods. However, this antioxidant activity was found to be strong significant correlation with phenolic contents (p
    • Abstract: Phosphorus (P) generally occurs in soils as the anions H2PO4- or HPO4-2 depending on soil pH. These anions readily react with soil cations such as calcium, magnesium, iron and aluminum to produce various phosphate compounds of very limited water solubility. Crop recovery of applied phosphate fertilizer can be quite low during the season of application. In addition, the large amounts of crop residue present in no-tillage production systems can lower soil temperature thus reducing root growth and nutrient uptake of plants even on soils not low in available Phosphorus (P). Specialty Fertilizer Products, Leawood, KS has developed and patented a product registered as AVAIL® that is reported to attract and sequester antagonistic cations out of the soil solution leaving more of the applied P in available form for plant uptake. The objective of this experiment was to evaluate the effectiveness of AVAIL treated P-fertilizer on growth, P-uptake and yield of irrigated corn (Zea mays L.) grown in a no-tillage production system. A 3-year experiment was conducted from 2001-2003 at the North Central Kansas Experiment Field, located near Scandia, KS, on a Crete silt loam soil (fine, montmorillonitic, mesic Pachic Arquistoll). Treatments consisted of three rates of P with or without AVAIL. A no P check plot was also included. When averaged over the years and P rates, the use of AVAIL increased yield of corn by 1.1 Mg ha-1. AVAIL also increased corn dry weight at the six-leaf stage, whole plant P uptake at the six-leaf stage and P concentration at mid-silk. The use of AVAIL proved beneficial in overcoming many of the problems associated with P nutrition in corn. AVAIL consistently increased P uptake and yield in this experiment.
    • Abstract: Biological wastes contain several reusable substances of high value such as soluble sugars and fiber. Direct disposal of such wastes to soil or landfill causes serious environmental problems. Thus, the development of potential value-added processes for these wastes is highly attractive. These biological wastes can be used as support-substrates in Solid-State Fermentation (SSF) to produce industrially relevant metabolites with great economical advantage. In addition, it is an environment friendly method of waste management. In this study were analyzed six different Mexican agro industrial residues to evaluate their suitability as support-substrate in SSF, between physicochemical properties that have included Water Absorption Index (WAI), Critical Moisture Point (CHP) and Packing Density (PD). The selection of an appropriate solid substrate plays an important role in the development of an efficient SSF process. The results provided important knowledge about the characteristics of these materials revealing their potential for use in fermentation processes.
    • Abstract: The insecticidal activity of essential plants oils against an important insect pest of fruit trees, the hairy rose beetle, was evaluated in topical and feeding applications in the laboratory. Essential oils that caused more than 50% mortality were further tested against the hairy rose beetle and the honey bee using different concentrations and their relative toxicities were evaluated. Results showed that eucalyptol and fir oils outperformed other tested oils and caused 72 and 64% mortality, respectively. These mortalities were not different from the application of the commercial insecticide, Deltamethrin. Moreover, eucalyptol and fir oils were more toxic to the hairy rose beetle than the dominant pollinator during fruit trees flowering, the honey bee. However, eucalyptol was relatively safer to the honey bees than fir oil. These findings indicate that eucalyptol might be applied during fruit trees bloom to control the hairy rose beetle even in the presence of honey bees if used for the crop pollination.
    • Abstract: In this study, we investigated the in-vitro antimicrobial activity of some medicinal plants in the Arabian peninsula, including Rhamnus globosa, Ocimum basilicum, Tecoma stans and Coleus forskohlii. Our results showed high inhibitory growth in yeast after treatment with R. globosa and O. basilicum. C. tropicalis was shown to be a sensitive strain with an inhibition of 29, 28, 35, 25 and 27 mm after treatment with R. globosa, R. globosa* “leaf with thorns,” O. basilicum, Tecoma stans and Coleus forskohlii, respectively. Thus, our results confirmed the fungicidal effect of O. basilicum and R. globosa with a 20 and 30% reduction in CFU compared with the starting inoculums in the time-kill.
    • Abstract: Identifying the best inbred combinations for the development of commercial hybrid of sunflower remains the main challenge to sunflower breeders. In the present research the level of heterosis of F1 hybrids, genetic diversity of parental lines based on SSR markers, as well as its connection with specific combining ability of sunflower were studied. Ten sunflower elite inbred lines (3 restorer lines and 7 cytoplasmic male sterility lines) and their hybrids were examined for plant height, seed yield, thousand seed mass, oil content and husk content. Field tests were carried out in 5-6 seasons. The level of heterosis was calculated using measurement of midparent heterosis. Genetic distance between pairs of tested sunflower inbred lines ranged from 0.45 to 0.74. Significant positive correlation was found between genetic distances among lines, measured using SSR markers and midparent heterosis for seed yield of hybrids (r = 0.79 p
    • Abstract: CMV is one of the major destructive viruses worldwide and commercial CMV resistant cucumber is very rare. Therefore we aimed to establish the ovule derived resistant lines used for the breeding program. Haploid plants of sixty-eight cucumber lines were successfully obtained by culturing the un pollinated ovaries harvested one day before an thesis on a modified MS medium supplemented with BAP and IAA at the ratio of 2:1 which was optimal to induce embryogenesis in most of the tested lines. For whole plant regeneration, another modified MS medium was used supplemented with a combination of 6-Benzylaminopurine (BAP) and Indole-3-Acetic Acid (IAA) (2:1) or BAP and IAA/6-(gamma, gamma-dimethylallylamino) purine (2ip) and IAA (5:1) and 5 ppm AgNO3. Ploidy levels of the regenerants were determined by cytological analysis. Thirteen out of 42 clones derived from 14 accessions showed a chromosome number of n = 7 and chloroplast number of 6/pair of guard cell, 24 lines were auto-dihaploid with n = 14 and a chloroplast number of 11-12/pair of guard cell. Twenty-eight Double Haploid (DH) lines were mechanically inoculated with CMV and the level of resistance was evaluated by using DAS-ELISA. Ten highly Resistant lines (R) included 70S2, 91e, 91.1, 93S4-1, 93S42-, 95S1-2, 95S2 DHS1, 117S2-1-3, 136.1 and 194S1 did not show any virus symptom and gave negative ELISA results. Twelve moderately resistant clones were identified including two clones from line 11, three clones from line 93, four clones from line 91 and one clone each from line 117S2 and 123, whereas clone 11.4 was moderately susceptible. Five DH clones; 117S2-1-1, 117S2-2, 117S2-4, 117S2-7 and 117S2-8were classified as highly susceptible.
    • Abstract: Тhe Melanocortin-4 Receptor (MC4R), a G-protein coupled receptor, is implicated in mediating the effect of leptin on food intake and energy balance. A previous candidate gene study reported an association between an MC4R polymorphism (Asp298Asn) and growth and meat productive traits of pigs. The aim of this work was to determine frequencies of the MC4R/Taq I genotypes and alleles in Danish Landrace (LD), Canadian Landrace (LC) and crossbred pigs Danish Landrace × Canadian Landrace (LD × LC) in breeding Cent “Plemzavod Jubilee” (Tyumen) Russia and to estimate their associations with some growth and meat traits. The polymorphism was identified by PCR-RFLP method. The traits studied were: Number of days to 100-kg, Average Daily Gain (ADG), Backfat Thickness (BFT), average daily Feed Intake (FI) and Length of Body (LB). In the all test groups we found a higher frequency of G allele (0.71) compared with the A allele (0.29). The results of present study suggest that the MC4R gene contributes to Days to 100 kg, ADG and BF. The heterozygous genotype AG was favorable in LD breed. The significant effects of-1.43 (LD male) and -2.81(LD female) for Days to 100 kg and of+61.17 (LD male) and +26.3 (LD female) for ADG were calculated. The homozygous genotype GG was favorable in crossbred LD × LC. The significant effects of +74.2 for ADG and-1.5 for BF were calculated. Therefore, the data support a role for the MC4R Asp298Asn polymorphism in the genetic basis of economically important traits in pigs of Russia. Further research is needed to determine the effect of this gene on growth, meat and reproduction traits in pigs of different breeds and crosses.
    • Abstract: The chemical equilibrium in the soil solution determines the dynamics of its material composition, migration and accumulation of salts. In the soil solution are formed electrically neutral ion pairs СаСО3°; CaSO4°, MgCO3°, MgSO4°, charged ion pairs CaHCO3+, MgHCO3+, NaCO3-, NaSO4-, CaOH+, MgOH+. The calculation method proposed for quantitative assessment of real ion forms in the soil solution of solonetz taking into account the ions association. Determination of real condition of the main ions in soil solution is based on ion association and its influence on physical and chemical properties of solution. Were calculated the free and associated ion form concentration according to analytical ion concentration. Were used an iteration to solve the equations of ion material balance, a linear interpolation of equilibrium constants, a Method of Ionic Pairs including a law of initial concentration preservation, a law of the operating masses of equilibrium system, the concentration constants of ion pair dissociation following the law of operating masses. Upon completion of iterative procedure, was determined the quantity of ion free form and a coefficient of ion association γe as the ratio of ions free form to its analytical content γe = Cass/Can. For calculation procedure were used the own software products. The association of ions varies in individual soils and soil layers, шncreasing the soil solution salinity amplifies the ions association. Depending on concentration and composition of soil solution the ionic pairs are: 15-45% Ca2+; 16-49% Mg2+; 0,6-8,4% Na+; 2,2-17,6% HCO3-, 16-51% SO42-, up to 88% CO32-. The proposed thermodynamic calculation method for quantitative assessment of real ion forms in the soil solution helps to explain the evolution of salted soils, maintain the soil, improve plant nutrition and irrigation.
    • Abstract: Phosphorus (P) is the most important element after nitrogen but P sorption properties are poorly documented in many soils. In this study, P sorption capacity in relation to incubation period and temperature under various P levels were determined for two different soil series (Rustam and Miani). Phosphorus was added at 5, 10, 25, 50, 100, 250, 500 and 1000 µg g-1 to the soils and incubated for the period of 1, 3, 7, 15, 30 and 60 days at 25 and 35±1°C temperatures. Phosphorus sorption was significantly influenced by the temperature, added P and incubation period. Clay content has major influence on P sorption. Rustum Series adsorbed more P than that of Miani Series. The P sorption was faster at high temperature (35°C). At the end of period in the Rustum Series with added 2.5 and 1000 µg g-1 P level, P sorption were found 0.7 and 943 µg g-1, respectively, at 25±1°C temperature, whereas at 35±1°C temperature the respective P sorption for same P levels were 1.8 and 987.0 µg g-1. In the Miani Series at 25±1°C temperature, P sorption was 0.7 and 941 µg g-1, while at the temperature of 35±1°C, P sorption were 1.0 and 986 µg g-1 soil. Increasing P levels, temperature and incubation, resulted in higher P sorption. Hence, high clay in combination with calcium carbonate contents enhanced P adsorption, while high organic matter and high native soil P resulted in lesser P adsorption.
    • Abstract: Okra Abelmoschus esculentus L. (Moench), is an economically important vegetable crop grown in tropical and sub-tropical as well as Mediterranean countries. The genome size of the Abelmoschus genus species is still rare. Ploidy determinations have traditionally been done by counting chromosomes of stained root tips, but this method is laborious and often difficult with species which have small chromosomes and high ploidy levels and can lead to misclassified. Flow cytometry has been widely used in various aspects of plant research, such as the determination of the DNA nuclear content. Nuclear DNA size of fifteen okra genotype was measured using flow cytometry. The data showed variation between Turkish genotype and Jordanian genotype. Genome size of okra ranged from 3.98 pg 2C-1 in Jordanian landrace to 17.67pg 2C-1 in Turkish landrace. The 2C genome size in Mbp ranged from 3897-17321 among Abelmoschus esculentus genotypes. Further studies is recommended to accurate chromosome count to be linked with the genome size.
    • Abstract: Nutrition department is one of the most important parts in a hospital since the performance of it has great impact on patients’ satisfaction. HACCP standard is one of tools for management and monitoring of the nutrition department. The aim of this study was reviewing the condition of HACCP standard requirements in nutrition departments of selected hospitals of Isfahan University of Medical Sciences. In this cross-sectional study, nutrition department of 12 hospitals of Isfahan University of Medical Sciences were studied. Data was gathered using questionnaires including 156 questions covering 5 domains through observation and interview. Statistical analysis was done using SPSS v16 and Kruskal-Wallis test. In total, rate of adherence to HACCP standard requirements in the studied hospitals was found as following: Modares (53.7%) and Seyedoshohada (53.1%) Hospitals, unacceptable conditions; Azahra (56.5%), Feiz (60.7%) and Amin (57.9%) Hospitals, moderate; Noor (68.2%), Ali-Asghar (68.2%), Eisabnemaryam (68.7%), Chamran (70.1), Shahid Beheshti (70%), Imam Musa Kazem (69.3%), Farabi (68.2%) and Kashani (68.5%) Hospitals, acceptable conditions. According to Kruskal-Wallis statistical test, scores from the five studied domains were not significantly different while the scores of the 12 hospitals were significantly different (p
    • Abstract: A greenhouse experiment was conducted to study the response of bell pepper to quality of irrigation water and irrigation regimes. The main treatments included non-saline water (EC-0.5 dS m-1) and saline water (EC-3.5 dS m-1). The sub-treatments included three irrigation regimes (at 100, 80 and 60% of crop Evapotranspiration (ETc)) in combination with three crop growth stages (vegetative, flowering to fruit set and fruit development to harvest). Application of saline water significantly reduced marketable fresh fruit yield from 5.47 to 2.60 kg m-2. Irrigation at 80% ETc till the end of vegetative stage and at 100% ETc later significantly increased the yield (5.01 kg m-2). Irrigation with non-saline water at either 80 or 60% ETc till the end of vegetative stage and at 100% ETc later resulted in similar fresh fruit yield. Saline water irrigation at 80% ETc till the end of vegetative stage and at 100% ETc later, proved superior to all the other treatments. Use of saline water (3.5 dS m-1) for irrigation of greenhouse bell pepper resulted in an increase in soil electrical conductivity and caused a drop in the fresh fruit yield by 72% as compared to irrigation with non-saline water (0.5 dS m-1). Irrigation at 80% ETc in the vegetative stage and at 100% ETc in the other two stages (flowering to fruit set and fruit development to harvest) recorded significantly higher total (5.52 kg m-2) and marketable (5.01 kg m-2) fresh fruit yield than all the other irrigation treatments. Saline water irrigation improved fruit quality with higher TSS (10.80%), Vitamin C (228.66 mg-100g) and acidity (0.305%).
    • Abstract: The Tofu Liquid Waste (TLW) as a pollution might be processed into biogas which was environmentally friendly and had potential to replace burning wood or oil. However, the waste could not directly be employed as the biogas substrate due to the high nitrogen content which was not suitable to the methanogen microorganism on the biogas digester and did not produce biogas. It was therefore necessary to adapt the carbon-nitrogen ratio in TLW with the addition of other organic materials that had a lower nitrogen content so it would be a suitable substrate for generating biogas. The research was aimed to evaluate the addition of the other organic material on the TLW to increase the biogas production. The results showed that TLW combined with sheep dung, cabbage waste, bamboo leaves and paddy straw respectively produced biogas as much as 14,183, 7,250, 2,400, 895 cm3 in 20 days. The 4 treatments gave the same quality of biogas, which was determined using the water boiling test. The pH fluctuation during the process was in the right pH for anaerobic digestion, thus it was not the limiting factor.
    • Abstract: More than half of the Australian cropping land is no-tillage and weed control within continuous no-tillage agricultural cropping area is becoming more and more difficult. A major problem is that the heavy herbicide usage causes some of more prolific weeds becoming more resistant to the regular herbicides and therefore more powerful and more expensive options are being pursued. To overcome such problems with aiming at the reduction of herbicide usage, this proposed research focuses on developing a machine vision system which can detect and mapping weeds or do spot spray. The weed detection methods described in this study include three aspects which are image acquisition, a new green plant detection algorithm using hybrid spectral indices and a new inter-row weed detection method taking the advantage of the location of the crop rows. The developed method could detect the weeds both during the non-growing summer period and also within the growing season until the canopy of the crop has closed. The design of the methods focuses on overcoming the challenges of the complex no-tillage background, the faster image acquisition speed and quicker processing time for real-time spot spray. The experiment results show that the proposed method are more suitable for the weed detection in the no-tillage background than the existing methods and could be used as a powerful tool for the weed control.
    • Abstract: One of the most fundamental aspects of healthcare for the elderly is planning to reduce challenges associated with their healthcare costs. The present study aimed to assess the status of the elderly health care costs in North Khorasan Province in 2013. In this descriptive-analytical study, all elderly citizens in North Khorasan Province comprised the study population. Sample size was found 400 people using cluster sampling method. Study tools for collecting data consisted of a questionnaire that was completed through interviews with the elderly or their first degree family members. Data were analyzed with SPSS-16 software using descriptive statistical tests of chi square and Kruskal-Wallis. Of the 400 participating elderly, 50.7% were female and the rest male. Mean total healthcare costs of the elderly were 3,335,200 IRR, with mean outpatient care costs of 2151900 IRR and mean in-patient service costs of 1183290 IRR. Mean costs in urban and rural areas were 2609220 IRR and 4039720 IRR, respectively. There was a significant relationship between variables of gender and the service providing center. Given the results obtained, mean costs incurred for the elderly in the province is high, particularly in the male elderly group. Outpatient costs are higher than the in-patient service costs. Furthermore, compared to the urban areas, costs are higher in rural areas.
    • Abstract: Water use efficiency in agriculture can be enhanced by several strategies mainly by reducing evaporation from the soil surface. The mulching techniques were being used widely in irrigated crop production worldwide. The mulching techniques can be also implemented in summer vegetables production under rain-fed conditions. The current study aimed at evaluating the effect of polyethylene black plastic mulch on growth and yield of okra, Abelmoschus esculentus and summer squash, Cucurbita pepo L. under rain-fed conditions of Jordan. Two field experiments were conducted during summer growing season at Al-Rabbah Agricultural Research Station, Mu’tah University, Jordan. Soil cover treatments were polyethylene black plastic mulch and no mulch (bare soil). The results indicated that the mulched plots had higher soil moisture content than bare soil plots, which has positively reflected on vegetative and yield parameters. Using polyethylene plastic mulch had pronounced positive effect on yield of okra and squash as compared to bare soil. Early, middle, late and total yield of both vegetable crops were significantly increased in plots covered with plastic mulch. In addition, fruit number and weight had also an increasing trend as fruit yield. Plots covered with black plastic mulch were produced higher fresh and dry weights of both vegetable crops. It ban be concluded that using black plastic mulch as a soil cover increased okra and squash vegetative growth and yield under rain-fed conditions.
    • Abstract: To control blue mold of apples caused by Penicillium expansum after harvest and during commercial cold storage, microwave exposure was investigated as a physical measure and compared with the use of calcium chloride and the systemic fungicide, carbendazime. Microwave exposure of Golden Delicious and Royal Gala apples at 2450 Mhz for 10, 30 and 45s was effective as 4% CaCl2 and carbendazime on significantly reducing the disease incidence %. Calcium chloride was more effective at 8% than 4% or at 1% and was as effective as carbendazime in reducing the mold severity and incidence. Microwave exposure for 10, 30 and 45s was as effective as 8% CaCl2 and carbendazime on controlling blue mold caused by P. expansum stored under the conditions of commercial cold storage. Different apple cultivars have different degrees of susceptibility to the blue mold. Granny Smith and Red Delicious were relatively more tolerant than Golden Delicious, Starking or Royal Gala. However, sight variations were found in their responses to different treatments. Therefore, 10-45s microwave exposure of apple fruits before cold storage alone or in a combination with other methods can be an environmental safe physical alternative to chemical fungicides for controlling P. expansum infections during cold storage.
    • Abstract: The levels and composition of agricultural dusts are influenced by animal species, production strategy, housing type and ventilation efficiency. Agricultural dust within animal houses is complex and consists of feed particles, microbes and their products, dander, fecal matter, gases, metals and other organic and inorganic components. Livestock and poultry production facilities may be categorized as confinement, semi-confinement or pasture-based. Characterization of animal husbandry building dust will provide insight into understanding exposures experienced by animals, workers and farm visitors. The goal was to characterize biophysiochemical features of livestock dusts from swine, small ruminant, equine, poultry and cattle husbandry units. Settled dust samples were collected from livestock and poultry housing units at the University Farm and other livestock farms across the state. Morphological features were determined by electron microscopy and gravimetry. Biochemical evaluation consisted of pH determination and trace metal detection via mass spectrometry. Biological assessment centered on bacterial characterization via selective media, DNA analysis and endotoxin quantitation. Morphological analyses revealed higher levels of respirable and thoracic particles in poultry, swine, small ruminant and equine units compared to the dairy unit (p
    • Abstract: Standards of Joint Commission International (JCI) emphasize on the organizational performance level in basic functional domains including patient right, patient care, medical safety and infection control. These standards are focused on two principles: Expectations of the actual organizational performance and assessment of organizational capabilities to provide high quality and safe Health Care Services (HCS). The aim of this study was to analyze the regression model of the Quality of Life (QOL) in cancer patients from Mazandaran province in 2013. This descriptive cross-sectional study was carried out on 185 cases after a chemotherapy treatment session during in the first three months that was referred to Rajaee Chemotherapy Center in 2013. The method of sampling was Purposive. General quality of life was assessed using WHO questionnaire (WHOQOL-BREF) and particular life quality was assessed using researcher-developed questionnaire. Data analysis was consisted of a multiple regression method and for comparison one-sample test of Kolmogrov-Smirnov was used. Statistical analysis showed that the average of general life quality, particular life quality and total average was evaluated, 1
    • Abstract: An experiment on a 50 ha center pivot field was conducted to determine the Vegetation Indices (VI’s) that were helpful in assessing the in-season performance of wheat crop treated with graded levels of irrigation water and fertilizers. The irrigation levels were at 100, 90, 80 and 70% evapotranspiration (ETc); however, the fertilizer levels of N: P: K kg-1ha included 300:150:200 (low); 400:250:300 (medium) and 500:300:300 (High). The crop was sown on January 1st and harvested on May 9th, 2012. Temporal data on biophysical parameters and reflectance of the crop in hyper spectral bands (350-2500 nm) were collected at booting and ripening growth stages (February 17th and April 5th, 2012). Results of the study revealed that many of the tested spectral indices showed significant response to irrigation levels. Out of those, only two spectral indices (Plant Senescence Reflectance Index ‘PSRI’ and Photochemical Reflectance Index ‘PRI’) also exhibited significant response to fertilizer levels. The Middle Infrared-Based Vegetation Index (MIVI) showed a significant response to the irrigation levels for both sampling dates. Among the tested spectral indices, Normalized Difference Infrared Index (NDII) and Normalized Difference Nitrogen Index (NDNI) exhibited the highest correlation to crop Leaf Area Index (LAI). Five indices showed the most response to wheat grain yield. These indices included Near Infrared band (NIR), Water Band Index (WBI), Normalized Water Index-1 (NWI-1), Normalized Water Index-3 (NWI-3) and Normalized Water Index-4 (NWI-4).
    • Abstract: Wheat plants (Triticum aestivum L., cv. Giza 168) irrigated with either 10 or 20% of Seawater (SW) were treated with aqueous extracts of green microalgae Scenedesmus obliquus and blue green algae Spirulina platensis (AESO and AESP 20 g (dry weight)/L) in order to increase wheat salt tolerance. Treated plants showed higher ability to tolerate salt stress (10 or 20% SW) by significant (p>0.5%) increasing of photosynthetic pigments (chlorophyll: Chlorophyll total, chlorophyll a and b types) and antioxidant low-molecular compounds (glutathione and carotenoids) contents. The increase of these contents was associated with increasing activities of antioxidant enzyme systems Superoxide Dismutase (SOD), Ascorbate Peroxidase (APX), Catalase (CAT) and total Peroxidase (POD). In addition, this observation was significantly correlated with decreasing of lipid peroxide products (TBARs) and sodium ions concentrations. However, wheat plant exposed to salt stress showed significant changes in all growth parameter and antioxidant low-molecular compounds and antioxidant enzyme activities compared with that in plants irrigated with regular water (tap water). In addition, plants treated with oxalic acid as bioregulator agent implied a moderate changes on growth parameters, antioxidant capacity includes non-enzyme and enzymatic systems compared with that in wheat plants treated with algae extracts. This study indicates that the algae extracts could be used as a promising plant growth enhancer for treating wheat plants irrigated with brackish water.
