Challenges and opportunities of indigenous dairy production and management: The case of selected rural villages in Bambasi District, Benishangul Gumuz Regional State, Western Ethiopia
No full textThe data sources were both primary and secondary data. To enable an analysis of data collected through questionnaire, Statistical Package for Social Sciences (SPSS) software (version 20) was used. The mean family size of the respondents was 6.04. The mean and SDs of cattle holding per household was (8.38±4.91). The total (67.9%) of respondents were having not have owned grazing land for their dairy cows. Tryponomiasis disease (Gendi) ranked first, Pasteurellosis disease second, and external parasites were third. (98.2%) respondents rear indigenous breeds. The mean daily milk production per cow was 1.4 liters. More than half of the milk was used for family consumption. Milk is sold in the area through an informal market directly to the retailer. Technical strategies to support smallholder cattle production should focus on improving technical and institutional constraints by providing adequate veterinary services, improving fodder cultivation, proper crop residue management, and improvement, supplying medical equipment and medicines, adequate extension service, improved water availability, and improving breeding systems. To ensure a reliable feed supply throughout the year, fodder conservation practices, especially hay and crop residues, should be encouraged.</p
Importance of fenugreek (Trigonella foenum-graecum L) to smallholder farmers in the case of Eastern and Southern Ethiopia
No full textInformation on the diversity of landraces, cultivation practices, and feeding habits is necessary to improve the crops through selection and/or hybridization. This study was conducted to generate information to document cropping practices, values, and socio-cultural aspects of fenugreek. A study was conducted in five districts of Oromia and one yem special districts at Southern Nations, Nationalities, and Peoples’ Regional States, and data were collected using structured and semi-structured interviews from 144 general and 24 key informants. Assessment of data was conducted through interviews with informants regarding cropping systems of the specific landraces, plant nomenclature of traditional landraces, distinctive criteria of each landrace, and use of fenugreek. R software version 4.1.2 and MS Excel 2010 were used to analyze qualitative data, quantify, sort, determine proportions and draw figures, percentages, means, and tables. The result indicated that Hulbata guracha and Hulbata Dima in Eastern Hararghe and Abesha abish and Orome abish in Yem Special district were reported as popular farmers’ cultivars. The farmers named the cultivars mainly based on seed color, seed source, and taste. Sole cropping of fenugreek was more common in Yem special district (65.3%), whereas intercropping with sorghum and Catha edulis (khat) was common in East Hararghe (27.3%) and crop rotation was practiced in both East Hararghe (97.2%) and Yem especial district (88.8%). The farmers in the study area use fenugreek mainly as food in East Hararghe (100%) while in Yem special district used mainly as a spice (100%). This is due to socio-cultural and knowledge differences on the importance of fenugreek in the study area that influence feeding habits, cultivation practice, and uses. </p
Effects of photo-selective netting in Summer Beefsteak Tomato (Solanum lycopersicum L.) cultivation on the environmental conditions under nets as well as growth and yield
No full textLocated in a subtropical zone, Taiwan has intense summer sunlight that affects beefsteak tomato cultivation. In this study, beefsteak tomatoes were grown net-house under photo-selective netting of different colors to investigate netting performance. A significantly higher photosynthetic photon flux density (PPFD) was observed under the 24-mesh white (W24) and 24-mesh pink (H24) netting. A difference between the four net-house was only observed for wavelengths of 500–599nm. In 32-mesh blue (B32), the red to blue (R/B) and red to far-red (R/FR) ratios were significantly lower across canopies. The photosynthetic capacity of photosystem II of leaves in W24 was the lowest among the four treatments. In all four, fruit growth was relatively low under the impact of high temperatures, with the lowest single fruit weight and the smallest number of fruits per plant observed in W24. In H24 and 24-mesh pink (HH24), the yield per plant was significantly higher. Significantly fewer whiteflies were observed in the netting houses in H24, HH24, and B32 than in W24. However, the netting still failed to prevent high temperatures at noon. In H24 and HH24, the amount of light retained in the canopies was greater, the photosynthesis capacity was unchanged, the fruit yield was greater and the number of whiteflies in the netting houses was significantly lower. Therefore, pink netting is recommended for beefsteak tomato cultivation.</p
In infectious diseases, Echinacea comes to the rescue
No full textE. purpurea has amazing medicinal properties that effectively deal with human diseases. Today, we find frightening figures in the WHO news about the increase in coronavirus infection and the number of deaths. This article presents a simple way of self-defense by increasing the body’s immune reactivity. In order to alleviate the condition and prevent not only COVID but also a variety of viral, as well as bacterial, and fungal infections, doctors can use the ornamental plant Echinacea (E.), which was once used by the indigenous people of America, the Indians, for almost all occasions. This article presents a small list of important biologically active components of E. and the range of their use, as well as a simple recipe for making a healing solution.</p

Thermodynamic-induced geometry of self-gravitating systems
No full textA new approach based on the nonequilibrium statistical operator is presented that makes it possible to take into account the inhomogeneous particle distribution and provides obtaining all thermodynamic relations of self-gravitating systems. The equations corresponding to the extremum of the partition function completely reproduce the well-known equations of the general theory of relativity. Guided by the principle of Mach's "economing of thinking" quantitatively and qualitatively, is shown that the classical statistical description and the associated thermodynamic relations reproduce Einstein's gravitational equation. The article answers the question of how is it possible to substantiate the general relativistic equations in terms of the statistical methods for the description of the behavior of the system in the classical case.</p

A case report on Anaesthesia and Ventriculo-Peritoneal Shunt with Hydrocephalus
No full textChildhood hydrocephalus is a common disorder in which too much Cerebrospinal Fluid (CSF) accumulates within the ventricles (fluid-containing spaces) of the brain and is usually the-ted by cerebrospinal fluid shunting using a ventriculoperitoneal or ventriculoarterial shunts. The most common condition is hydrocephalus, where there is dilation of the ventricular system due to an obstruction in the flow of CSF or decreased absorption of CSF by the arachnoid villi. Shunting of CSF is the treatment of choice in childhood hydrocephalus. </p
Selenium supplementation in the prevention of coronavirus infections* (*In Memory of Laszlo G. Egyud)
No full textSelenium (Se) is a ubiquitous element akin to sulfur (S) existing in the Earth’s crust in various organic and inorganic forms. Selenium concentration varies greatly depending on the geographic area. Consequently, the content of selenium in food products is also variable. It is known that low Se is associated with an increased incidence of cancer and heart diseases. Therefore, it is advisable to supplement your diet with this element albeit in a proper form. Although blood increased concentrations of Se can be achieved with various pharmacological preparations only one chemical form (sodium selenite) can offer true protection. Sodium selenite, but not selenate, can oxidize thiol groups in the virus protein disulfide isomerase rendering it unable to penetrate the healthy cell membrane. In this way, selenite inhibits the entrance of viruses into the healthy cells and abolishes their infectivity. Therefore, this simple chemical compound can potentially be used in the recent battle against the coronavirus epidemic.</p
Dissipation kinetics and the pre-harvest residue of chlorantraniliprole in pigeon pea Cajanus cajan L. succulent pods Using Ultra-High-Performance Liquid Chromatography with Photodiode array detector (UHPLC-PDA)
No full textStudies were conducted to evaluate insecticide residues of Chlorantraniliprole in pigeon pea succulent pods after foliar application. Chlorantraniliprole was sprayed at 0.6ml/l on pigeon pea crop at the pod formation stage to control pod borers like Helicoverpa armigera and Maruca vitrata. Samples were drawn at 0, 1, 5, 10, 15, 20, 25, and 30 days after spray. A validated liquid chromatography method with a Photodiode Array (PDA) detector was used for the residue analysis of chlorantraniliprole. Separation was achieved through the C18 column in the reverse phase. The calibration graphs of chlorantraniliprole in acetonitrile solvent or five blank matrices were linear within the tested interval of 0.1 to 1ppm with a coefficient of determination over 0.9990. Dissipation of chlorantraniliprole was studied in first-order kinetic models (for which the coefficient of determination, R2 was 0.8684). Residues of chlorantraniliprole was 3.57, 3.16, 1.61, 1.13, 0.49, 0.21, 0.05 and 0.00mg/kg at 0, 1, 5, 10, 15, 20, 25 and 30 days after spraying. The residue level reached below the tolerance limit (MRL) (2mg/kg BW) of Codex Alimentarius Commission (CAC) on Pesticide Residues after 5 days of spray and below the detectable level after 25 days of spray in succulent pods and recorded a biological half-life of 4.36 days.</p
