  • Method on Anaerobic Biogas Generation From Cow Dung and Water Hyacinth

    • Authors: Nitin Gupta; S. M. Nafees, Seema Agarwal
      Abstract: Under the right conditions, liquid manure will break down into biogas and a low-odor effluent. Biogas can be burned to produce heat, electricity, or both the anaerobically-digested manure, can be stored and applied to fields with significantly less odor than stored, untreated liquid manure. Anaerobic digestion does not reduce the volume or nutrient value of manure. If dilution water is added to the system, the volume of material to handle is increased.The following test can help you determine if anaerobic digestion is a viable option for your farm. If most of the following statements describe your farm, anaerobic digestion may be compatible with your operation.Manure is currently handled as a liquid. Very little bedding or frozen manure is handled and the manure in the handling system is free from high levels of copper sulfate and antibiotics.Odor control is a major concern.There is space on the farm to expand the manure handling system with the possibility for gravity flow from a barn to an anaerobic digester or from a digester to a manure storage.Someone on the farm has the interest, time, and technical skills to learn about the anaerobic digestion process, make repairs, and perform general maintenance on equipment.Resources are available to finance an anaerobic digestion system.Adhering to recommended safety practices is standard procedure on the farm.

  • Impact of Malaria Parasitemia on Some Liver Enzymes among Adults Patients
           Attending University of Maiduguri Teaching Hospital, Maiduguri, Borno

    • Authors: Ibrahim Usman Ishaku; Adamu Inuwa, Yakaka Adam, Inuwa Yahaya, Mamoon Asiya
      Abstract: Nearly half of the world's population is susceptible to malaria, a potentially fatal disease. When the parasite infection is left untreated or treated incorrectly, it can lead to catastrophic side effects such as chronic renal disease, liver illness, and even death. The goal of this study was to examine the blood and liver enzymes of UMTH, Maiduguri's malaria patients. The ALP, AST, and ALT of the malaria parasite were measured using conventional techniques. In this study, 125 malaria patients at the UMTH were divided into groups according to their sex, age, gender, and malaria density. Their ALP, AST, and ALT blood liver enzyme levels were examined and compared to those of 125 control patients. The research found that the majority of malaria patients Thirty-eight (30.4%) of the malaria patients, or (58.4 percent) of the total population, were males and were between the ages of 25 and 31. They predominantly have low malaria densities (+). The mean ALP, AST, and ALT values for malaria patients were 5.801, 12.760, and 20.470, respectively. This difference was extremely significant (P 0.05). Our research revealed 2.995, 2.056, and 3.594 as very significant differences in liver enzymes. The average levels of ALP, AST, and ALT in malaria patients with (+) were 7.178, 1.854, and 7.345, respectively. indicated a significant statistical difference when compared to patients with malaria who had (++) (p 0.05/0.01). In comparison to age groups 18-24 years, 25-31 years, 32-38 years, and 39-45 years, the value of liver enzymes in malaria patients showed no significant changes at 0.621U/L, 0.120U/L, and 0.496U/L, respectively. However, as previously mentioned writers have noted, that more work must be done to implement control strategies and eradicate malaria infection in this area.

  • Effects of Malaria Parasitaemia on Electrolytes (NA, K, CL, HCO3) and Some
           Liver Enzymes (AST and ALT) in Patient Attending University of Maiduguri
           Teaching Hospital

    • Authors: Ibrahim Usman Ishaku; Dr. Adamu Inuwa
      Abstract: Malaria is a life threatening disease, with nearly half of the world’s population being vulnerable to the infection. The parasitic infection, when untreated or improperly treated, is characterized by fatal complications such as chronic kidney disease, liver disease and death. This study was designed to analyze blood electrolytes and liver enzymes of malaria patients attending UMTH, Maiduguri. Standard methods were used to determine malaria density, Na+, K+, Cl- and HCO3-) ALP, AST and ALT. Majority of the malaria patients (39.4%) are within the age group of 25 to 31 years. One hundred and sixty one (89.4%) out of 180 malaria patients have malaria density of (+) while 19 (10.6%) have malaria density of (++).The mean value of chloride of 102.29 ± 6.89 mmol/L in malaria patients was significantly lower than that of control subjects of 103.07 ± 5.81 (p˂ 0.05). The mean value of ALT of 10.35 ± 4.33 U/L in male malaria patients was significantly higher than that of female malaria patients of 8.87 ± 4.13 (p˂ 0.05). The mean values of Na+, K+, Cl-, HCO3-, ALP, AST and ALT in malaria patients with (+) showed no statistical difference compared to malaria patients with (++) (p˃ 0.05). The mean values of HCO3- of 20.65 ± 1.39 mmol/L, 20.72 ± 1.50 mmol/L, 21.20 ± 1.31 mmol/L, 21.23 ± 1.34 mmol/L and 22.14 ± 1.07 mmol/L for 18-24 years, 25-31 years, 32-38 years, 39-45 years and 46-52 years, respectively showed statistically significant difference. It is concluded that majority of malaria patients who are males and adults, seek medical attention at early stage of malaria infection and at the point of enrolment where the malaria infection have little or no effects on electrolytes and liver enzymes. This is an indication of effectiveness of awareness and control measures against malaria infection. However, as emphasized by previous authors, efforts are still needed toward control measures and eradication of malaria infection in this region.

  • Effect of Curriculum Duration and Entry Qualification on the Development
           of Bachelor Nurse Students’ Critical Thinking Competence in the Centre
           Region of Cameroon

    • Authors: Dr. Paul Marius Eyinga
      Abstract: The criticality of Critical Thinking in the profession of nurse is proved in every relevant literature. It is an imperative tool that nurses need to master so that they can provide quality care. But a critical analysis of bachelor nursing curricula revealed that all over the world bachelor degree programmes vary in their duration and sometimes in their entry qualification. The duration varies from two semesters to four years. Entry qualification varies from High School Diploma to Diploma in Nursing. We were then able to ask ourselves what is the effect of this variation on the development of nurse student critical thinking, especially in the Centre Region of Cameroon' This pushed us to state two objectives for this article: To find out whether there is any effect of entry qualification on students’ Critical Thinking competence in bachelor degree curricula in nursing schools in the Centre Region of Cameroon; To find out whether there is any effect of the programme duration on students’ Critical Thinking competence in bachelor degree curricula in nursing schools in the Centre Region of Cameroon. To reach these objectives, a cross-sectional survey was used. A convenient sample of 229 students was selected comprising 102 holders of High School Diploma and 127 holders of Diploma in Nursing. A critical thinking test made up of six open-ended questions was used for data collection. Descriptive and inferential statistical analysis were used base on independent T-test. Research ethical principles were rigorously observed. Findings revealed that, in nursing schools in the Centre Region of Cameroon, students with Diplomas in nursing (m = 7.37) exhibited better Critical Thinking skills than those with Baccalauréat (m = 5.56). and that, students who were offered a more extended programme (m=8.10) exhibited better Critical Thinking skills than those in who were offered a shorter programme duration (m=5.87). These findings confirmed the results of many other studies on similar topics.

  • Innovative Method of Storage of Agricultural Machinery

    • Authors: Xojimatov Azizbek Asomiddinovich
      Abstract: In the aggressive environment of agriculture in the decomposing-mechanical erosion of materials is observed the phenomenon of structural adaptation of the initial structures of the upper layers to a more energetically viable form of loading under these conditions. Agricultural machinery operates in a changing external environment. That is, weather, humidity, heat, soil, salts, mineral and organic fertilizers, biological waste. All this has a negative impact on the main working parts of the machine over time. The most important of these effects is corrosion. Corrosion occurs as a result of chemical influences and climatic conditions and can be divided into several types. Atmospheric degradation, subsurface degradation, dissolution of dissolved salts, biochemical degradation, local degradation, chemical degradation. The most corrosive elements of agricultural machinery are the mineral and organic fertilizers (salts that do not penetrate into the soil and are not absorbed by plants). In the aggressive environment of agriculture, the phenomenon of structural adaptation of the initial structures of the upper layers to a more energetically viable form of the load is observed in the decomposing-mechanical erosion of materials.

  • Distributed Active and Reactive Power Control With Smart Microgrid

    • Authors: T. U. Kurbaniyazov
      Abstract: Energy is one of the leading contributors to the economic development of any country. Energy plays a vital role for developing countries like India because it has to serve its large population [1]. Establishing a large power grid serving billions of people requires a significant investment. The world’s growing population has created a lot of problems that exist today. The most important issue of all is global warming caused by the abundance of greenhouse gases present in the atmosphere. Many of these greenhouse gases such as CO2 are produced from power plants all over the world burning fossil fuel. To reduce these emissions out into the atmosphere alternative sources of energy must be used. In the last two decades, both solar and wind energy have become an alternative to conventional energy resources [2]. These alternative energy resources are non-polluting, abundant, and renewable. In recent years, thanks to the advance in technology, better manufacturing processes have decreased their capital costs thus making them more attractive. This has led to the outburst of the distributed generators (DGs) and Smart Grid concepts [3]. The United States of America is among one of the leading countries in the world and as such, they invest lots of money and resources in the renewable energy sources [4]. Figure-1 shows Uzbekistan maps of the solar; (this illustration is provided by the Energy Sector Management Assistance Program (ESMAP)).
