  • Short-Term Effects of Aroma Therapeutic Herbal Steam on Heart Rate
           Variability and Stress

    • Abstract: This experimental research aims to examine the short-term effects of aroma therapeutic herbal steam on heart rate variability and stress. In this experimental study, the participants were 60 diabetic patients with stress who had rated their stress in the Suang-prung Stress Test-20 at the level of 3 or higher. They were divided into the treatment group (n = 30) and the control group (n = 30) using a simple random sampling method. The former was administered aroma therapeutic hot steam, whereas the latter received standard conventional medical care. Both before and after the experimental period, both groups were assessed in terms of their Heart Rate Variability (HRV). The within-group HRV values, namely SDNN, RMS-SD, LF and HF, for both the treatment and the control groups pre- and post-treatment differed significantly (p<0.05). Additionally, when the between-group values post-treatment were considered, the SDNN, RMS-SD and LF values for the treatment group were significantly higher than those for the control group (p<0.05). Based on the findings, it can be concluded that aroma therapeutic hot steam will interact with factors triggering stress and enhance parasympathetic nervous system function, thereby reducing stress levels. This is proof that the treatment should improve the conditions of diabetic patients suffering from stress.
  • Characterization of the Earth's Surface State by Unsupervised
           Classification: Case of Vegetated, Aquatic and Mineral Surfaces

    • Abstract: In this study, we propose an unsupervised classification scheme based on the Dempster-Shafer Theory (TDS) and the Dezert-Smarandache Theory (DSmT) to characterize vegetated, aquatic and mineral surfaces. From pre-processed ASTER satellite images (georeferencing, geometric correction and 15 m re-sampling), neo-channels were produced by determining the spectral indices NDVI, MNDWI and NDBaI, considered as sources of information for classification of a given pixel. NDVI is a contrast function to highlight vegetation. By account, the MNDWI makes it possible to characterize the water and the NDBaI makes it possible to recognize the mineral resources. Then, we modeled respectively the formalisms of the DST and the DSmT, these formalisms are modeling tools close to advanced probabilities based on the notions of belief and fusion functions to take into account certain imperfections (uncertainty, ignorance, etc.) encountered in the acquisition of images. In addition, the DST manages a formalism of disjunction between the sources during the DSmT simultaneously manages a disjunction and a conjunction between the sources. Next we realized the algorithms and related codes that we implemented in the MATLAB environment. Our contribution lies in taking into account the imperfections (inaccuracies and uncertainties) linked to source information through the use of mass functions based on a simple Gaussian distribution support model in order to model each focal element independently of the others and to evaluate the belonging of a pixel to a class with respect to the majority of elements representing said class. The resulting results show that the DST approach is relatively satisfactory for the unsupervised classification of mineral surfaces and aquatic surfaces while it is not satisfactory for vegetated surfaces according to all proposed models. As for the DSmT, it presents satisfactory results for all the models proposed. The model with the exclusion integrity constraint E∩V ∩ M = φ was selected as the best model because having, in addition to an average rate of well-graded pixels of 93.34%, a compliance rate (96, 37%) with the terrain higher than those of the other models implemented.
  • Sentiment Analysis: Comparative Study between GSVM and KNN

    • Abstract: Sentiment classification aims detecting general opinion of users in social media towards business products or daily life events. The classification tells whether sentiment is positive or negative. Techniques of sentiment classification are categorized into lexical analysis and machine learning techniques. In this paper, we propose a comparative study between SVM applied genetics (GSVM) against KNN algorithm in terms of speed and accuracy. We present also an experimental study of sentiment classification on different domains movie reviews, financial and amazon toys products. The experimental results shows that GSVM achieves a classification accuracy of 92% and KNN achieves 87% on movie reviews dataset. For classification speed, KNN shows a remarkable improvement (above 10% improvement) in comparison with GSVM.
  • Determination of Dynamic Viscosity of Viscous Oils using Mach Zehnder
           Digital Holographic Method

    • Abstract: The digital in-line holography based on Mach Zehnder interferometer (MZDIH) was setup for the determination of dynamic viscosity of the viscous oils. The spherical irons were used as the falling objects in the viscous oils. The hologram images of the iron falling along its entire path were recoded as a video file on the CMOS camera. The recorded hologram images were reconstructed on the holoviewer program via MATLAB. Then, the diameter and velocity of the iron were obtained. Finally, the dynamic viscosity of viscous oils were determined and compared with standard values. From the experimental results, it can be concluded that the MZDIH method is the simple and precise tool for determining the dynamic viscosity of fluids.
  • Juvenile Delinquency: Evidence of Challenges in Rehabilitation

    • Abstract: Juvenile delinquency is a global phenomenon that affect children’s developmental process and represent a significant concern for the society. Despite the fact that it is a global issue, its effects are felt more in developing countries such as Ghana due to inadequate resources available to rehabilitate them. However, the study explored the procedure used in admitting inmates into the juvenile detention facilities and challenges in rehabilitating them and recommended strategies based on findings to improve on the rehabilitation system. Using a quantitative research methodology, simple random and purposive samplings were used in selecting 94 respondents for the study at the senior correctional centre. Data obtained from the inmates was analyzed with SPSS and descriptive statistics with frequency distributions were employed to explain the data. The findings indicated challenges that affect both care takers and inmate at the centre regarding human resources, inadequate training period, facility to house inmate and the proper procedure for admission into the correctional facility. These challenges showed that, there are gaps in the rehabilitation process which mission is to make delinquent children valuable members of the society after they are released. Rather many juvenile delinquents stand high risk of becoming criminals in their adulthood.
  • Evaluation of Nutritional Quality of Some Wild Edible Plants in Central
           Cross River, Nigeria

    • Abstract: According to the Nigerian National Population Commission 2006, the population of the nation was conservatively estimated to be over one hundred and seventy million. The challenge of nutritional quality to feed an increasing national population places a higher demand on poorly grown conventional plants. Thus the need to incorporate wild edible plants to bridge the extended gap between the conventional vegetable and the wild indigenous edible plants informs this research. The daily intake of vitamins and minerals are obtained from vegetables. Wild edible plants serve as food and medicine. In this study, the delicacies were prepared from two novel wild edible vegetables - Ceiba Pentandra (CPD) and Ficus glumosa (FGD). They were evaluated for nutritional quality. Their minerals and vitamins content were determined using standard methods. These delicacies were fortified with a diet of experimental rats. Twenty four (24) albino rats weighing 43.99 - 81.49 g were randomly arranged into six groups (n = 6) of six rats per group. Two groups were fed with the formulated experimental diets, while the other two were fed with protein-free (casein) and basal diets. Vitamins C and E, carbohydrate and protein were significant in CPD delicacy at (28.47±3.17%). The mineral composition showed low Na+ level, while Ca2+ concentration was also low in CPD and FGD. Phosphorus and Mg+2 were high in FGD. The FGD-fed rats had a low biological value (%) (1.38±0.01%) compared to CPD (2.29±0.01) and reference (casein) group (3.02±0.01). The reference group consumed the highest amount of food -97.06±14.70 g, followed by the basal group (88.98±10.61, with CPD having (76.46±18.78) and FGD (48.27±18.27), respectively. There were no differences in the body weight, protein efficiency ratio, net protein utilization, net protein retention, true digestibility, fecal and carcass protein levels in all the test groups. Findings indicate that nutrients from these wild vegetable delicacies may have good quality and could meet the nutritional needs of the consumer if utilize as per the standard.
  • Comparison of 10 cm and 50 cm Long Iodine Cells in Iodine-Stabilized Diode
           Laser-Pumped Nd:YAG Laser at 532 nm

    • Abstract: An iodine-stabilized diode laser-pumped Nd:YAG laser system at 532 nm was developed at the National Institute of Metrology of Thailand (NIMT) for the first time in Thailand. Two iodine cells with the lengths of 10 and 50 cm were used for the comparison of frequency stability of Nd:YAG laser. The experiment was set for phase modulation spectroscopy. The Nd:YAG laser was locked to the a10 component of the R(56)32-0 transition of iodine molecule. The variation of wavelength with time and the frequency stability were carried out at various iodine cell temperatures of 20, 10, 5, 1, -1, -3 and -5°C. The results from the frequency stability measurements showed that the lowest Allan standard deviation value of 6.643×10-10 was obtained at -5°C for 50 cm long iodine cell. From this Allan standard deviation value, it can be concluded that the iodine-stabilized diode laser-pumped Nd:YAG laser system at 532 nm developed in this study is acceptable to be used with a gauge block interferometer for the length calibration of the gauge block.
  • Microwave-Sensitive Reactors to the Rescue: From Microwave-Assisted
           Chemistry to Environmental Applications

    • Abstract: The idea of using microwave sensitive reactors is relatively new in chemistry and environmental areas. Applications in both areas might be different but the effects can be amazing. Flow through reactors coated with thin metallic films using a variety of deposition techniques have been used as vessels to conduct reactions in flow under microwave irradiation. The metal coating not only did not provide any impediment to the process, it served a two-fold purpose. Metallic coatings acted as catalysts for the flow through processes; in addition the flowed reactions were tremendously accelerated due to unusually high temperatures generated within reactors because of coupling of microwaves to metal films. The methodology of developing microwave active reactors has been successfully extended to environmental applications, transcending chemistry, such as distillation of saline/brackish waters for the purpose of generating potable water. The experimental distillation device described here as a proof of concept, will lay a foundation for a high throughput water sanitizing process, delivering potable water to large groups of people.
  • A Real-Time Optimization Approach to the Efficiency of a Photovoltaic
           System by a Hybrid Tracking Technique using LabVIEW

    • Abstract: Among the lines of research on improving the efficiency of a photovoltaic panel, sun tracking techniques occupy a large part. In this article, an extension of Laboratory Virtual Instrument Engineering Workbench (LabVIEW); LabVIEW Interface For Arduino (LIFA) is used. It allows the driving of an Arduino board from LabVIEW, on which a collaboration technique between two categories of pursuit is developed: The first is sensory and the second is pre-programmed. This hybrid two-axis technique is characterized by impulse control strategist with pre-programmed control and dual sensory correction. The results reveal that the hybrid tracking system gave an additional energy gain of about 36% compared to a fixed photovoltaic panel system. Thus, it has practically a percentage increase of 2 and 2.3% respectively to the two techniques used.
  • q- sl2 and Associated Wave and Heat Equations

  • Minimizing Transmission Time under Required System Capacity Constraint in
           Stochastic-Flow Networks

    • Abstract: In the case of an existing limited capacity of the system called required system capacity, in this study a new method is presented to determine the disjoint paths to send data from the source to the sink. System reliability is evaluated as the probability that a specified amount of data can be transmitted from a source to a sink through two disjoint paths, subject to a time threshold and a required capacity. In addition, we study the effect of using the proposed method on the reliability evaluation in comparison with other previous methods.
  • Management of Effective Factors in Components’ Supply Chain on
           Losses of Electric Distribution System

    • Abstract: Restructuring in the electrical distribution utilities, the loss management is one of the critical activities to enhance network efficiency. Accordingly, management of technical loss would be the main target of the asset managers. For loss management, the usual methods of loss calculation and estimation need numerous data which is not used to real networks. In this research, a practical method for loss management is introduced from the viewpoint of components’ supply chain to the network. For this purpose, sub-indictors are extracted using focus group for each process of this chain and their probability distribution functions are calculated. Then, permissible values of sub-indicators are determined by the Delphi method and to calculate new probability functions, the deviation of each process is calculated. Finally, a real network with historical data is used here to study the proposed method. The results illustrate that the most deviation is in the sub-indicator design process about 91% in the viewpoint losses.
  • The Impact Dimensions of Service Quality on the Acceptance Usage of
           Internet Banking Information Systems

    • Abstract: Nowadays, banking transactions are one of the most important daily services that fulfill a society needs. The broadly growth of information technology usage pushed banking institutions to embrace advanced technology to launch new electronic services. Internet technology has influenced the banking practicability because of its capability to enhance performance of financial operations. A major concern of Internet banking systems is the customers’ perception of service quality that render Internet banking a unique environment due to the lack of physical interaction between bank personnel and the customer. Thus, there is a necessity need for banking institutions identify factors that convince customers and raise their intention towards usage of these services. The purpose of this paper is to set forth a valid means and contribute to the field of measuring online service quality with a focus on optimizing this perception via electronic transactions in the domain technology of the banking industry and its reliability by examining the most important factors affecting customer perception towards acceptance of Internet banking in Jordan. The conceptual framework formulated and developed in this research study is an extension to the Technology Acceptance Model (TAM). The model was tested with a survey sample of 500 banking customers chosen randomly. The findings of the study indicate that all mentioned factors in the hypothesized model (TR, SP, QI, AW, PU and PEU) have significant impact within creating a positive atmosphere for stimulating the acceptance and use of Internet banking systems. Data analysis is based on the Statistical Package for Social Science (SPSS).
  • Effects of Enriching Nitrogen and Phosphorus on the Growth of Sargassum
           Podacanthum Cultured in Potassium-Fortified Inland Saline Water

    • Abstract: Potassium-fortified inland saline water (K+ISW) has shown potential for growing marine species, including seaweed species. The response of a brown seaweed species, Sargassum podacanthum, to nitrogen and phosphorus enrichments were evaluated by culturing the species for 84 days in K+ISW and comparing it with Ocean Water (OW). The culture media were enriched weekly with ammonium chloride and sodium dihydrogen phosphate, with ammonium and phosphate ratios of 10:1 at five different concentrations 80:8, 120:12, 160:16, 200:20 and 240:24 μM. The culture medium with no enrichment was used as a control. The water quality and biomass of S. podacanthum were measured fortnightly. The S. podacanthum biomass increase significantly with different concentrations of the nutrient supplementations. The standing biomass and Specific Growth Rate (SGR) of S. podacanthum were similar in OW and K+ISW in the absence of any nutrient supplementation and at the supplement concentration of ammonium and phosphate 160:16 μM. However, from day 42 onwards, at the ratios of 80:8, 120:12, 200:20 and 240:24, S. podacanthum cultured in OW grew significantly faster than in K+ISW. In K+ISW, optimal growth of S. podacanthum was observed at the 160:16 and the increase in biomass was significantly higher than the initial biomass until day 70, whereas at the other four nutrient supplement concentrations, the S. podacanthum biomass remained unchanged during the entire culture period. The nitrite, total Kjeldahl nitrogen and phosphate concentrations in water were found to be significantly (p
  • Effects of Temperature and pH on the Growth of Sargassum linearifolium and
           S. podacanthum in Potassium-Fortified Inland Saline Water

    • Abstract: This study tested the effects of temperature and pH on water quality and the growth of Sargassum linearifolium and S. podacanthum in potassium-fortified Inland Saline Water (ISW) of Western Australia (WA), at two levels of pH (low pH range of 5.5-6.5 and ambient pH 7.0-8.2) and two levels of temperature (high temperature 26-27°C and ambient room temperature of 20-22°C) in triplicate for 42 days. The pH of ISW in WA varies from 3.9 to 9.1, whereas the temperature is from 6.1-28.1°C. The results showed that the high temperature initiated the mortalities of the both Sargassum species from the first 14 days of culture period. The high temperature also resulted in a reduction of dried weight and ash content of these two species of Sargassum by the end of the trial. S. linearifolium temperature tolerant threshold was larger than S. podacanthum. Since the day 14, the S. linearifolium biomass and specific growth rate were higher than S. podacanthum at both temperature levels under ambient pH. Higher crude protein in S. linearifolium than S. podacanthum was also recorded at high temperature. Ambient pH and ambient temperature resulted in higher biomass and higher specific growth rate than low pH and high temperature in both species, which is recommended for Sargassum spp. growth.
  • Chronological Age and Dental Age Using Demirjian in Down Syndrome Children

    • Abstract: Down syndrome is a chromosomal abnormality (trisomy 21) characterized by an extra chromosome 21. People with Down syndrome have impairement in mental and physical development, including delayed dental development. Dental age is stage of development of teeth measured by maturation stage of teeth. This study aims to determine or asses the growth or maturation of permanent teeth in children with Down syndrome. This research was a cross-sectional analysis. Analysis test using paired t-test to compare the average of chronological age to dental age, also unpaired t-test for comparing the dental age of children with Down syndrome to normal based on chronological age. The result showed that there was significant difference between chronological age and dental age in children with Down syndrome (p-value <0,05). Thus, there was the difference of dental age between children with Down syndrome and normal but not significant (p-value >0,05). The conclusion of this study showed that dental age more late than chronological age in children with Down syndrome. In spite dental age in Down syndrome children is descriptively later than in normal.
  • The Human Resource Approach to Innovation in the Recent Growth of
           Floriculture Sector in Rural Areas of Sicily

    • Abstract: The variety and variability of the most commonly recognized innovation categories (product, process and management) have been the structural basis of the recent growth of floriculture sector in Sicily. However it is due to the virtuous character of farmer (vision, knowledge, skills and abilities) the ability to integrate the specific functions involved of the farm with innovation. As well as that, fundamental the relational behaviors within external environments characterized by non-deterministic stimulation-response mechanisms. This paper presents the main results of a motivational investigation of the figure of the farmer of the floriculture sector in Sicily.
  • Soft Sensors for Monitoring Combustion Quality and Flue Gas Emissions in
           Power Station Boilers

    • Abstract: This research work includes a combination of Fisher’s Linear Discriminant (FLD) analysis by merging Radial Basis Function (RBF) Network and Back Propagation Algorithm (BPA) for monitoring the combustion conditions of a coal fired boiler. The CCD Camera is used to capture the two dimensional flame images. The features such as images, average intensity, area, brightness and orientation etc., of the flame are extracted after pre-processing the images. The FLD is applied to reduce the n-dimensional feature size to 2 dimensional feature size for faster learning of the RBF network. Also video processing has been done to extract three classes of images corresponding to different burning conditions of the flames. For various flame conditions, the corresponding temperatures and flue gas emissions are obtained using analyzers and sensors. The combustion quality indicates the air/fuel ratio which can be varied automatically. The proposed feed forward control scheme presents an alternative for the existing set-up for measuring SOx, NOx, CO and CO2 emissions that are detected from the samples collected at regular intervals of time in the laboratory or by using gas analyzers. Further training and testing of Parallel architecture of Radial Basis Function and Back Propagation Algorithm (PRBFBPA) with the data obtained has been done and the performance of the algorithms is presented.

  • A Proposed Design for Illumination and Cameras Surveillance System for
           Optimum Supervision at a Perimeter Area of Nuclear Facility

    • Abstract: An important component of a comprehensive security plan is lighting. Security Protective Lighting has three functional objectives: To illuminate a person, object, place or condition of security to permit observation and identification, to be a physical deterrent through the glare effect of direct light on the human eye and to be a psychological deterrent creating in an intruder's mind the awareness that he or she will be discovered and observed during any unauthorized entry attempt. The most obvious reason for protective lighting is to make certain any person, object, place or condition will be sufficiently illuminated to provide effective security in a given region. Where perimeter lighting is required, the lighting units for a perimeter fence should be located a sufficient distance within the protected area and above the fence so that the light pattern on the ground will include an area both inside and outside the fence. Perimeter lighting should be continuous and on both sides of the perimeter fence and should be sufficient to support CCTV and other surveillance equipment where required. The cone of illumination from lighting units should be directed downward and outward from the structure or area being protected. The lighting should be arranged so as to create minimal shadows and minimal glare in the eyes of security guards. In this study a proposed design for security lighting and cameras surveillance system for optimum supervision at a perimeter area of a hypothetical nuclear facility will be presented. The illumination poles, lamps type, towers space distance, average and minimum Lighting Levels and Tilt Angle, required for camera surveillance system will be computed and determined. The work provides the requirements of cameras surveillance system at nuclear reactors isolation zone. Width of images sensitive area, lens focal length, lens format and angel of view will be determined by calculation method. The work determines cameras type, distributions, camera’s parameters and formulas according to the physical protection design process. Cameras angles of view, Lens Format, Lens focal length, F-Number and angle of view will be calculated. The optimum designing results for the security lighting (35 poles with 250 watt high pressure sodium and 34 m poles span with minimum lighting level equal 7 lux. The optimum CCTV design resulting in 15 cameras with length format 0.25 inch, length focal length 50 mm, F-stop number 1.8, angle of view 5.26 degree. In the future work; designers should consider the natural properties of reflectance, light absorption capacity, mobility and an object's inherent sensitivity to light to be sufficient to support CCTV system.
  • Shots Temporal Prediction Rules for High-Dimensional Data of Semantic
           Video Retrieval

    • Abstract: Temporal consistency stands as a vital property in semantic video retrieval. Few research studies can exploit this useful property. Most of the used methods in those studies depend on rules defined by experts and use ground-truth annotation. The Ground-truth annotation is time-consuming, labor intensive and domain specific. Additionally, it involves a limited number of annotated concepts and a limited number of annotated shots. Video concepts have interrelated relations, so the extracted temporal rules from ground-truth annotation are often inaccurate and incomplete. However, concept detection score data are a huge high-dimensional continuous-valued dataset and generated automatically. Temporal association rules algorithms are efficient methods in revealing the temporal relations, but they have some limitations when applied to high-dimensional and continuous-valued data. These constraints have led to a lack of research used temporal association rules. So, we propose a novel framework to encode the high-dimensional continuous-valued concept detection scores data into a single stream of numbers without loss of important information and to predict the neighbouring shots’ behavior by generating temporal association rules. Experiments on TRECVID 2010 dataset show that the proposed framework is both efficient and effective in encoding the dataset which reduces the dimensionality of the dataset matrix from 130×150000 dimensions to 130×1 dimensions without loss of important information and in predicting the behavior of neighbouring shots, the number of which can be 10 or more, using the extracted temporal rules.
  • The Exchange Rate Pass-Through into Inflation with Symmetric Oil Price
           Shocks: An Empirical Analysis for Saudi Arabia: 1970-2015

    • Abstract: The purpose of this paper is to analyze theoretically and empirically the relationship between inflation as a dependent variable and bilateral exchange rate, output gap and symmetric oil price shocks. The ARDL methodology is employed considering the period of 1970-2015. The exchange rate pass-through to inflation will be thoroughly investigated. Johansen’s testing procedure confirms the existence of long-run relationships between consumer price inflation, exchange rate, symmetric oil price changes and output gap as a proxy for aggregate demand. The estimation results reveal that depreciation of the exchange rate and the symmetric oil price shocks are main factors responsible for long-run domestic consumer price inflation in Saudi Arabia. Although the output gap as a proxy for aggregate demand had the right sign but its contribution is little in explaining the variations in domestic inflation in the long-run. This could be attributed to the sufficient Saudi economic capacity. In economic literature, the findings here are in line and consistent with other researchers’ estimation results.
  • Influence in the Drink Preparation Mode Associated Coffee the Antioxidant
           Capacity of Different Brands

    • Abstract: Coffee is one of the most consumed beverages worldwide and commonly present on Brazilian tables. It is known for its health benefits, mainly ascribed to its antioxidant compounds. Because of a lack of standardized analytical methods to evaluate these compounds in coffee, the variety of products sold, as well as the influence of the form of preparation of the beverage upon the content of the antioxidants, this work is intended to evaluate the reducing capacity of beverages prepared with samples of roasted and ground coffee, as well as the influence of the preparation, employing the Folin Ciocalteu (FC) spectrophotometric method. After the validation of the method, the reducing capacity in commercial coffee beverages was evaluated as well as the influence of different ways of preparation, including infusion and decoction. The optimization steps and validation of spectrophotometric method FC allowed to obtain more reliable results, facilitating the analysis of the evaluated coffee samples and ensuring greater security in the analysis of the results. The preparation technique also influenced the reductive capacity of drinks, as different preparation methods resulted in different values and the decoction the most efficient. This information can be valuable to consumers, who can choose to domestic preparation techniques that result in a coffee drink with better content of antioxidant compounds.
  • Efficiency of EDTA and TWEEN 80 for the Removal of Chromium using Soil
           Washing Technologies

    • Abstract: The study on the efficiency of chelate and surfactant for the removal of chromium using soil washing technology of which the chelate is EDTA and surfactant is TWEEN 80 at concentrations of 8, 16 and 32 millimoles was separately conducted. The experiment soil was synthetic soil with chromium contamination for 2 years. In this study, 20 g of contaminated soil would be washed with 200 milliliters of EDTA and TWEEN 80 with pH values of 2, 4, 6, 8 and 10 before being shaken at speeds of 90, 120 and 150 rpm for 15, 30, 60, 90, 120 and 180 min and at every 3 h until it reached its equilibrium point at room temperature. After that it was filtered with filter paper before digestion with acid whereupon the obtained solution would be further analyzed. The study result revealed that EDTA could remove chromium best at a concentration of 32 millimoles with pH of 10 and shaking speed of 120 rpm and it could eliminate chromium at the level of 38.54%. In the meantime, TWEEN 80 could remove chromium best at a concentration of 32 millimoles with pH of 10 and shaking speed of 150 rpm and it could eliminate chromium at the level of 9.86%. Therefore, when comparing efficiency between EDTA and TWEEN 80, the researcher concluded that EDTA had higher efficiency in removing chromium from soil than TWEEN 80.
  • Drought Tolerance and Evaluation of Genetic Changes in Rice Mutant Lines

    • Abstract: The genetic improvement of rice through mutation induction to obtain drought resistance is essential for stable and adequate rice production would enable us to anticipate the rice yield-reducing effects of global warming. The aim of this research was to evaluate the rice mutant lines showing tolerance to drought condition and their genetic relationship using SSR markers. Mutant lines were obtained by irradiation of Mira-1 rice variety at primordial state by 25 and 50 Gy doses. Twenty numbers of M4 rice mutant lines, cv. Mira-1 as wild type, cv. Gajah mungkur as positive control and cv. IR64 as negative control were chosen in this study were planted in PVC cylinders in the green house. The result showed that the agronomic trait of rice mutant lines were better than their wild type. Root length of 17 number of mutant lines are longer than their wild type and Gajah mungkur, the longest root obtain was 71.5 cm on 7J4 rice mutant line compared to Mira-1 only which was 25 cm. The number of lateral roots and seeds content per panicle higher than their wild type and positive control. Based on SSR marker linked to root depth, DRO1 showed that 12 numbers of mutant lines polymorphic and changing of genetic of mutant lines which was indicating the mutant lines were tolerant to drought compared to their wild type. The molecular information of rice mutant lines is essential for further development of a new superior variety of rice, which would be an improvement of the variety already existed.
