Abstract

Ethiopia like most sub-Saharan countries had been suffered by obsolete pesticides accumulated at various places across the country. Disposal of obsolete pesticides in Ethiopia had been inadequate and presently huge quantities of obsolete pesticide stocks are found accumulated in substandard stores owned by ministry of health, ministry of agriculture and various investors, presenting potential risks to nearby residents and the environment. This assessment study of obsolete pesticide stocks’ status was aimed at evaluating the status and effects of obsolete pesticide stocks on public health and the environment and indicate a corrective action. The methodology employed to collect data was field observation, interviews and questionnaires dispatched to study site residents. Results of the study indicated that obsolete pesticide stocks were depreciated, kept in torn out drums, burst open sucks, indiscriminately mixed up with other chemicals, exposed to sunlight, wind drift and runoff water and easily accessible to animals and humans. Thus obsolete pesticide stocks accumulated in inefficiently secured stores could be a threat not only to public health and the environment but also to the fast growing economy of the country. Awareness raising and training given to the public on the dangers involved with obsolete pesticide stocks was inadequate. To aware the community and conduct further research to ascertain the actual situation of obsolete pesticide stocks accumulated across the country need to be carried out before the present situation causes more social and environmental problems.

Abstract

During the summer 2014, dark black symptoms beneath the leaf surfaces were observed on the Populas alba L species in the south Kashmir. In the later stages of development the infection subtends the whole surface resulting in leaf collapse. Fungal isolates were recovered directly from the structures present on the lesions. Puri fied DNA from each isolate was amplified using the random amplified polymorphic DNA technique recruiting the ITSI (TCCGTAGGTGAACCTGCGG) and ITS4 (TCCTCCGC TTATTGATATGC) specific primers. Amplification products visualized on agarose gel showed specific band pattern for each isolate. The mycotaxonomic characterization and phylogenetic interpretations showed the emergence of fungal species, Meliola sp. KY623717 with genetic variance of 2% in internal transcribed spacer (ITS) region of rDNA from closely related species under geographically distinct region.

Abstract

Considering its implementation, the linguistic and cultural diversity of Mindanao, however, brings much complexity to the issue of language policy in education. With Mindanao’s more than 26 provinces and over 25 million population (Philippine Statistics Authority, 2005), the government offers a challenging environment for implementing a language policy that is suppose to serve all Mindanao regions and the rest of the country. This language policy is part of a rising trend around the world to support mother tongue instruction in the early years of a child‘s education. In Southeast Asia, this is apparent in a growing number of educational programs that use the mother tongue approach. Good examples can be found in Cambodia, Indonesia, Malaysia, Thailand, Timor L‘Este and Vietnam (UNESCO, 2007). With all this, the program is now on its third year as it was implemented in 2011. Looking at this, the shift towards mother tongue-based multilingual education is not a walk in a highway. Numerous challenges need to be addressed like the production of materials, training of teachers, management of resources, and perhaps, the socio-cultural support to enhance this project. Concentrating on the MTB-MLE program challenges, this study is hoping to underwrite something of relevant contribution to the success of the MTB-MLE in Iligan City.

Abstract

This paper investigates the determinants of Sudan balance of payments using annual data on balance of payments (BOP), foreign debt (ED), exchange rate (EX), inflation (INF), gross domestic product (GDP) during the period (1980 - 2016). The paper elaborates the problem regarding the impact of foreign debt on the balance of payments. The paper built on the fundamental assumption that the foreign debt linked to a positive relationship with the balance of payments by running VECM Approach. Results of the study indicate that there is a direct correlation between the balance of payments and foreign debt, and an inverse relationship between the balance of payments and all of the inflation, gross domestic product and exchange rate during the forementioned period. The paper recommends that Sudan should not totally dependes on foreign aid in solving its economic problems which entails to transfer big amount of the national product to meet the commitments towards those foreign countries, the need for coordination between macroeconomic policies and domestic economic policies in order to increase output domestic product, economic policies are functioning to reduce the ratio of foreign debt and the reduction of inflation and bring about stability in the exchange rate which leads to improving the balance of payments to be adopted by Sudan.

Dynamic Response to Moving Distributed Masses of Pre-stressed Uniform Rayleigh Beam Resting on Variable Elastic Pasternak Foundation

Dynamic Response to Moving Distributed Masses of Pre-stressed Uniform Rayleigh Beam Resting on Variable Elastic Pasternak Foundation

Abstract

The dynamic response to moving distributed masses of pre-stressed uniform Rayleigh beam resting on variable elastic Pasternak foundation is examined. The equation governing this problem is a fourth order partial differential equation with variable and singular co-efficients. To solve this cumbersome equation, the method of Galerkin approach is adopted to reduce the governing differential equation to a sequence of coupled second order ordinary differential equation which is then simplified further with modified asymptotic method of Struble. The more simplified equation is solved using the Laplace transformation technique. The closed form solutions obtained are analyzed in order to show the conditions of resonance, and to show that resonance is attained earlier in moving mass system than in the moving force system. The results in plotted graphs show that as the axial force, the rotatory inertia, foundation modulus and shear modulus increase, the deflection of the elastically supported non-uniform Rayleigh beam decreases in each case. The transverse deflections of the beam on variable Pasternak elastic foundation are higher under the action of moving masses than those when only the force effects of the moving load are considered. This implies that resonance is reached faster in moving mass problem than in moving force problem.

Keywords: Pasternak foundation. Shear deformation. Resonance. Critical speed. Natural frequency. Axial force. Modified frequency.

Abstract

Yellow, cyan, magenta and black inks were extracted from documents printed using two common brands of printing cartridge in Nigerian market and analyzed to identify / compare the functional groups present using Fourier Transform Infra-red Spectroscopy (FTIR). The FTIR spectra obtained were found to show highly characteristic absorption bands depending on the composition of the printer inks. Also, the results indicated the presence of triarylmethane dyes, epoxy resins, alkyd resin and esters in all the inks as they are peaks assigned to the vibration of aliphatic ester, asymmetrical and symmetrical stretching. The pure ink and its extract from the same band were also found to exhibit similar FTIR spectra while inks extract from different brands exhibits marked difference in absorption bands. This research can provide valuable information if an admitted sample is provided for comparing with the suspect printed document.

Abstract

The inhibitive and adsorption properties of ethanol extract of Bryophyllum pinnatum leaves were studied using weight loss, potentiodynamic polarization, Scanning Electron Microscopy (SEM) and Fourier transformed infra-red spectroscopy (FTIR) methods of monitoring corrosion. The results obtained, indicated that ethanol extracts of Bryophyllum pinnatum leaves is a good adsorption inhibitor for the corrosion of zinc in sulphuric acid solutions. The adsorption of the inhibitor on zinc surface was found to be spontaneous and supported the Langmuir adsorption model. From the calculated values of free energy of adsorption, the activation energy and the variation of inhibition efficiency with temperature, a physical adsorption mechanism has been proposed for the adsorption of ethanol extract of Bryophyllum pinnatum leaves on zinc surface. Results from potentiodynamic polarization study indicated that Bryophyllum pinnatum is a mixed-type corrosion inhibitor. Analysis of spectra obtained from Fourier transformed infra-red spectrophotometer (FTIR) revealed that some functional groups presence in the spectra of the inhibitors were missing in the spectra of the corrosion products which also indicated that there is an interaction between zinc and the inhibitor.

Abstract

Bread is the most important staple food in the Western world and it is generally viewed as a perishable commodity, The presence of mould, another concern is the potential mycotoxins production that may cause public health problems Lactic acid bacteria (LAB) as bio preservation organisms are of particular interest: they have been used for centuries as starter cultures in the food industry and are able to produce different kind of bioactive molecules that inhibit fungal spoilage. The efficacy of antifungal LAB as bio-preservative in bread manufacture industry is quite relevant. The inhibitory activity against molds. Thus, Lactic acid has the potential to improve the shelf-life of bread under normal circumstances. The use of LAB as protective cultures may possess several advantages over the use of purified bacteriocins; the cultures may serve as the source of bacteriocins as well as a broad range of other antimicrobials including organic acids, carbon dioxide, ethanol, hydrogen peroxide, and diacetyl These microorganisms may also exhibit antimicrobial activity against spoilage microorganisms, thus increasing shelf life. Therefore, LAB can be used as protective cultures to inhibit pathogens and/or prolong the shelf life of foods, or they may be useful as bio-sanitizers to reduce or eliminate colonization of pathogens in an environment. The proper choice of LAB (either alone or in combination with other hurdles), as well as the selection and development of strains with best performance for each particular food, may greatly reinforce the competitiveness of bio preservation methods in the food industry.

Abstract

As a young researcher in the academics, I wonder what should be the essentials of a good research. A candid research should begin with a central theme which should be spell out in a specific manner. It should also address the targeted audience. Detailed narrations should follow-up afterwards in separate paragraphs for the harmonious blend of each topic and concept. Finally, as concluding remarks, the summary of the research should be depicted in a lucid manner. The trend of research that I have seen in many of the research outcome has been worse.

Abstract

Sorghum national average productivity in Ethiopia is 2.1 tons/ha which is far below the global average of 3.2 tons/ha due to the problem of drought, striga, insect pest (stalk borer, midge, and shoot fly),diseases (anthracnose and smut), soil fertility decline, inadequate adoption of existing improved varieties, lack of high yielding and good quality sorghum varieties. The Ethiopian government is pursuing a strategy of improving Sorghum productivity primarily through agricultural intensification, involving an increased use of inputs, including seeds of improved crop varieties and involved sorghum plant breeding since 1976 with different objectives and released many improved sorghum varities. However the yield performance, adoption intensity and adoption rate of the released sorghum varieties at regional and national level were not well studied. So this research intiated with the following objectives:  To summarize the trend of sorghum production and productivity in Ethiopia.  To asses performance of improved sorghum varieties yield and their level of adoption.  To evaluate factors that determines adoption of improved sorghum in Ethiopia. The assessment was also done using secondary data from different sources. So, as a conclusion to increase the adoption rate and intensity of the released sorghum varieties across their suitable agro ecology and based on the objective of the target improved sorghum varities at the time of variety registration, agricultural extension should be strength and linkage between the department of integrated crop improvement with socio economics and agricultural extension should be improved. With this at variety development farmers better to participate and include their selection criteria, interest, problem and increase adoption of the improved sorghum varieties. Socio economic, demographic and institutional factors also played negative impact on slow adoption of the improved sorghum varieties.

Abstract

Nephrotoxicity stands amongst the most widely recognized kidney issues and happens when human body is presented to a medication or toxins that give harm to kidneys. At the point when kidney harm happens, patient cannot free his assortment of abundance urine, and squanders. It can be acute and chronic. Lead and cadmium are the two most commonly known nephrotoxic metals. People who work or live in such environmental settings which made them exposed to these toxins are at risk. Prolonged exposure to these metals leads to their accumulation in tissues especially kidneys. Proximal tubular dysfunction, hypertension, hyperuricemia and decreased glomerular filtration rate are the common effects of cadmium and lead nephrotoxicity respectively. Proper medication can reduce these dysfunctional ties but best treatment is to reduce exposure so one can avoid the accumulation of these toxins in kidneys and other tissues.

Abstract

Seedling of Ofada rice (Oryza sativum L) were raised in sand (swampy) and clay (upland) cultures under 500mg/kg lead acetate and 500mg/kg garlic aqueous extract for 40-days. The uptake and distribution pattern of lead with possible induction of oxidative stress and likely alteration in the inherent antioxidant defense systems of the rice plants were determined. The inhibitory potential of garlic against lead-induced oxidative stress in rice seedling was also assessed. From the results, rice seedlings grown for 10-40 days under 500mg/kg lead acetate showed significant (P<0.05) increase in level of lipid peroxides in roots, indicating enhanced lipid peroxidation compared to control. However, incubation of garlic extract with supernatants of rice root and shoot caused a significant (P<0.05) reduction in the accumulation of lipid peroxides in a concentration dependent manner. In addition, there was a marked increase in antioxidant enzymes activities in lead acetate treated seedlings, where the shoot maintained higher defensive enzyme activity than roots. The results suggest that lead-induced oxidative stress could be salvaged by garlic extract and antioxidant enzymes are biomarkers for lead-induced oxidative injury in rice plants.

Abstract

The project work aims at designing a student attendance system which could effectively manage attendance of students of the department of Computer Science and Engineering at Jatiya Kabi Kazi Nazrul Islam University. In this project work, attendance is marked after student’s biometric identification. For student identification, a fingerprint recognition based identification system is used. Fingerprint features are considered to be the best and fastest method for biometric identification. These features are more secure to use and unique for every person that don’t change in one's lifetime. Fingerprint recognition is a mature field today, but still identifying individual from a set of enrolled fingerprints is a time taking process. It was very necessary to improve the fingerprint identification system for implementation on large databases, e.g. of an institute or a country. In this project, the minutiae algorithm is used to develop the identification system which is faster in implementation than any other available today in the market. The proposed automated attendance system based on fingerprint recognition was tested on a class of student fingerprint databases and achieved significant results for taking an attendance of the students of the Department of Computer Science and Engineering. The proposed system has been implemented using C# programming paradigm platform.

Keywords: Attendance System. Biometric Features. Fingerprint Recognition. Identification. Verification.
