Pesticides are risk factors in human life causing chronic human health effects. They are commonly used across the globe to enhance human endeavors. In Ethiopia, pesticides are widely used by local farmers and governmental organizations for pest control purpose. Pesticide residues in food items have been a concern to the consumers and environment they live in. Therefore, this study was aimed at determining the amount of organochlorine and organophosphate pesticide residues in cereal crops in Bench-Sheko Zone, Ethiopia. A cross-sectional laboratory-based study design was employed to determine the amount of pesticide residues. The samples were extracted using a Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) extraction and clean up method. Finally, the extracted samples were injected into gas chromatography tandem mass spectrometer and the types and concentrations of pesticide residues were analyzed. The highest concentration of endosulfan sulfate (0.076 mgkg-1) was detected in rice, followed by dimethoate (0.068 mgkg-1) and p,p ′ -DDE (0.087 mgkg-1) in sorghum and common millet, respectively, in the samples obtained from the Gurafarda site.The highest concentration of p,p ′ -DDT (0.133 mgkg-1) was detected in common millet, followed by aldrin (0.082 mgkg-1) and dimethoate (0.077 mgkg-1) in sorghum and common millet, respectively, in the samples obtained from the North Bench site. In addition, aldrin detected in rice, sorghum, and common millet obtained from the three sites was a residue of above the maximum residual limits set by Codex Alimentarius regulations and European Union. The finding shows that an indication of the widespread use of pesticides in cereal crops.

Human Health Effects

Abstract Pesticides are very important risk factors in human life causing chronic human health effects. Pesticides are commonly used across the globe to enhance human endeavors. In Ethiopia, pesticides are widely used by local farmers and governmental organizations for pests control purpose. However, majority of pesticides are not specifically targeting the pest. As a result, pesticide residues in food items have been a concern to the consumers and environment they live in. Therefore, this study was aimed to determine the amount of organo-chlorine and organo-phosphate pesticide residues in cereal crops in Bench-Maji Zone, Ethiopia. Experimental study design was employed to determine the amount of pesticide residues and cereal crops were bought from the local farm sites and market of purposively selected sites. The samples were extracted using a Quick, Easy, Cheap, Effective, Rugged and Safe extraction and clean up method. Finally, the extracted samples were injected into Gas chromatography tandem Mass Spectrometer and the types, and concentrations of pesticide residues were analyzed using linear regression equation that obtained from calibration curves. The highest concentration of Endosulfan sulfate (0.076 mgkg− 1) was detected in rice, followed by Dimethoate (0.068 mgkg− 1) and p,p’-DDE (0.087 mgkg− 1) in Sorghum and common millet, respectively in the samples obtained from Gurafarda site. The highest concentration of p,p’-DDT (0.133 mgkg− 1) was detected in common millet, followed by Aldrin (0.082mgkg− 1) and Dimethoate (0.077mgkg− 1) in Sorghum and common millet, respectively in the samples obtained from North-Bench site. In addition, Aldrin detected in rice, sorghum and common millet obtained from the three sites was a residue of above the maximum residual limits set by Codex Alimentarius regulations and European Union. The finding shows that the detection of pesticide residues in cereal crops in samples obtained from the study area. It is an indication of the widespread use of pesticides in cereal crops production. Therefore, strict supervision of pesticide application in the fields, regulation of informal veterinary drug store and implmentation of integrated vector management strategy are recommended.

In this paper, a design procedure for cold-formed channels periodically closed on their open face and utilized as joist web members is detailed. The design method for periodically closed sections is based on the representation of the cross-sectional properties using Fourier series introduced in Timoshenko quotients for the determination of the buckling loads about each of the three member axes. Once those loads are computed, they are used in the current framework of the North American Specification for the design of cold-formed structures with appropriate effective length coefficients. The proposed design methodology is compared with test results obtained from 36 stub column samples and 21 full-scale joist specimens, also presented in this paper.Key words: cold-formed struts, periodically varying cross sections, steel joists, flexural–torsional buckling, effective length coefficients.

New Development

The Northeast region of Nigeria has been experiencing the devastating impact of Boko Haram insurgencysince 2009, which triggeredhumanitarian crisis and destruction of infrastructure,such as schools, hospitals, roads, bridges as well as homes and farmlands, leading to many becoming internally displaced persons and refugees. Both governmental and non-governmental organizations have been mostly providing relief services and materials, whilst only few Federal Government agencies and State Governmentsare providing reconstruction and rehabilitation due to insufficient sources of funds(Olaseni, 2012).The emergence of Sukuk to Nigerian Capital Market is a new development that provides alternative funding avenue for both State and Federal Governments to finance projects and infrastructure development for nation building (Alaro, 2020).It is against this backdrop that this study aims to reviewthe approaches of financing rehabilitation and reconstruction programmes in the Northeast and examines how the potentials ofSukuk financing could properly be utilized to complement the infrastructural deficit in the region. Thus, the research is an exploratory qualitative research that sourced cross sectional primary data collected through the use of structured questionnaire. Multistage purposive sampling method was employed in selecting the respondents for the study across the study area. Thematic Analysis was employed as the method of data analysis. Both descriptive and inferential statistics were used to summarize and interpret the results of the thematic analyses of the data obtained.Keywords: North-East, Reconstruction, Rehabilitation and Sukuk Financing

Morphological Differences

It has been demonstrated that cross sections of bundles of hair can be effectively studied using image analysis. These studies can help to elucidate morphological differences of hair from one region of the body to another. The purpose of the present investigation was to use image analysis to determine whether morphological differences could be demonstrated between male and female human Caucasian terminal scalp hair.Hair samples were taken from the back of the head from 18 caucasoid males and 13 caucasoid females (Figs. 1-2). Bundles of 50 hairs were processed for cross-sectional examination and then analyzed using Prism Image Analysis software on a Macintosh llci computer. Twenty morphological parameters of size and shape were evaluated for each hair cross-section. The size parameters evaluated were area, convex area, perimeter, convex perimeter, length, breadth, fiber length, width, equivalent diameter, and inscribed radius. The shape parameters considered were formfactor, roundness, convexity, solidity, compactness, aspect ratio, elongation, curl, and fractal dimension.

Botanical composition of grasses is one of the most important indicators the biological value and quality of the obtained hay and pasture forage, the longevity of hayfi elds and pastures depend on. The issue of changing the botanical composition of agrophytocenoses is especially important in the context of global climate change, which in recent decades is also manifested in the territory of Ukraine, as it is possible to establish the most adapted species of legumes and cereals to adverse weather conditions and to identify eff ective technological methods of managing these processes for maximum conservation economically valuable species in the herbage. The purpose of the research is to establish the infl uence of diff erent ways of sowing of clover and alfalfa cereal crops agrophytocenoses on the formation of their botanical composition. Field studies have established diff erent eff ects of conventional in-line, cross-section and cross-sectional methods of sowing on the formation of botanical composition of grass mixtures of clover meadow (Trifolium pratense) varieties Sparta and Pavlyna with timothy meadow (Phleum pratense) and fenugreek multifl oral (Lolium multifl orum) and of agrophytocenoses of alfalfa of Sinyukha and Seraphima sowing varieties with reed fire (Festuca arundinacea Schreb) and middle wheatgrass (Elytrigia intermedia). For the average of four years of life of clover and alfalfa cereal crops agrophytocenoses, the highest proportion of legume component was observed with split-cross sowing – 51.6 % for Sparta, 53.1 % for Pavlyna, 60.3 % for Seraphima and 61.6 % for the Sinyukha variety. In the fourth year of life (the third year of use) of sowed leguminous-cereals agrophytocenoses, the preservation of the legume component was 14.6–15.5 % in clover-cereals grass mixtures with the Sparta variety and 16.0–16.8 % with the Pavlyna variety. In alfalfa grasslands, these indicators were 54.0–55.1 % with Seraphim and 55.0–56.2 % with Sinyukha. Among the studied varieties of clover meadow and alfalfa sowing proved better in the conditions of the Forest Steppe of western Pavlyna and Sinyukha. Cross-sectional and divided cross-sectional sowing of legumes and cereals mixtures proved to be better compared to conventional row crops in terms of conservation of economically valuable grass species. Key words: agrophytocenosis, botanical composition, clover meadow, alfalfa sowing, sowing methods.

Window Design

Three elements mainly wind, water and sun seemed to determine in ancient ages the basic phenomena of life on Earth. Architectural history documented the importance of sun influence on urban and building construction already in layouts of Mesopotamian and Greek houses. Not only sun radiation but especially daylight played a significant role in the creation of indoor environment. Later, in the 20th century, a search of interaction between human life in buildings and natural conditions were studied considering well­being and energy conscious design recently using computer tools in complex research and more detail interdisciplinary solutions. At the same time the restricted daytime availability of natural light was supplemented by more efficient and continually cheaper artificial lighting of interiors. There are two main approaches to standardize the design and evaluation of indoor visual environment. The first is based on the determination of the minimum requirements respecting human health and visibility needs in all activities while the second emphasizes the behaviour and comfort of occupants in buildings considering year­around natural changes of physical quantities like light, temperature, noise and energy consumption. The new current standardization basis for daylight evaluation and window design criteria stimulate the study of methodology principles that historically were based on the overcast type of sky luminance pattern avoiding yearly availability of sky illuminance levels. New trends to base the daylight standardization on yearly or long­term availability of daylight are using the averages or median sky illuminance levels to characterise local climatological conditions. This paper offers the review and discussion about the principles of the natural light standardization with a short introduction to the history and current state, with a trial to focus on the possible development of lighting engineering and its standards in future.

У статті теоретично обґрунтовано феномен конструктивного самозбереження особистості як ознаки самоактуалізації, розкриття власного потенціалу і побудови перспективи розвитку особистості та емпірично виявлено ознаки психологічної детермінації домінуючого інстинкту у конструктивній самореалізації жінок з різним соціальним статусом. Зазначено, що проблема самозбереження асоціюється з особливостями прояву інстинкту самозбереження людини, але потреби вищого порядку зумовлюють соціальну природу її поведінки, яка локалізована у найвищій точці самореалізації. Теоретично обгрунтовано, що самореалізація визначає тенденцію раціональної організації життя людини та проявляється у її почутті задоволеністю життям. З’ясовано, що психологічну основу конструктивного самозбереження становлять індивідуально-типологічні характеристики людини, які відображають психофізіологічні та психосоціальні резерви самореалізації особистості. Розроблена програма емпіричного дослідження, а також комплекс використаних методів математичної обробки результатів дослідження дає змогу конкретизувати психологічний зміст детермінації домінуючого інстинкту у конструктивній самореалізації жінок вікового діапазону 35-45 років та з різним соціальним статусом. У жінок, які виховують проблемну (хвору) дитину, домінує інстинкт "егофільного типу", що виражається у їх надмірному егоцентризмі і супроводжується низькими показниками самоактуалізації, на відміну від досліджуваних жінок, які виховують здорових дітей і у яких на фоні вираженої тенденції до самоактуалізації домінує базовий інстинкт "дослідницького типу" та "лібертофільного типу". This article theoretically proves constructive phenomenon of self identity as signs of self-disclosure own potential and prospects of development of individual construction. In addition, it empirically showes signs of psychological determination of the dominant instinct in a constructive self-determination of women with different social statuses. It was noted that the issue of self-preservation is associated with the peculiarities of manifestation of self-preservation instinct of man, but it needs higher-order cause social nature of the behavior that is localized at the highest point of self-realization. It theorized that self-realization determines the trend of rational organization of human life and manifests itself in its sense of life satisfaction. It was found that the psychological basis of constructive self-preservation of the individual make individually-typological characteristics of a person that reflect physiological and psychosocial reserves of self-realization. The developed program of empirical research, as well as the methods used complex mathematical processing of results of research allows to specify the content of the psychological determination of the dominant instinct of constructive self-realization а women age range of 35-45 years and with different social status. Women who bring up the problem child dominates the instinct of self-preservation, which is reflected in their excessive self-centeredness, and is accompanied by low levels of self-actualization, as opposed to the study of women who are raising healthy children and that against the backdrop of a pronounced tendency to self-actualization, dominated by basic instinct "research type" and "independent type."

Garbage can be interpreted as a consequence of the activities of human life. It is undeniable, garbage will always be there as long as life activities continue to run. Every year, it can be ascertained that the volume of waste will always increase along with the increasing pattern of public consumerism. The landfill which is increasingly polluting the environment requires a technique and management to manage waste into something useful and of economic value, Bantas Village, Selemadeg Timur District, Tabanan Regency currently has a Waste Management Site (TPS3R) managed by Non-Governmental Organizations (KSM ) The source of waste comes from Households, Stalls, Restaurant Entrepreneurs, Schools, Offices and Ceremonies which are organic and inorganic waste. The waste management system at Bantas Lestari TPS with 3R system is Reduce (reduction of waste products starts from the source), Reuse (reuse for waste that can be reused) and Recycle (recycling waste) to date it is still running but not optimal. The method used in this research is descriptive quantitative with data analysis using SWOT analysis. This study produces a Waste Management Strategy which is the result of research from the management aspect, aspects of human resources and aspects of infrastructure facilities.
