Nutrient utilisation in growing Cambodian cattle

Natural forages are an important part of the diet of cattle in Cambodia, but their nutrient value, particularly in terms of macro-minerals, may be inadequate, leading to potential mineral deficiencies in grazing cattle. This thesis compared the nutrient composition of six forage types (rice bran, rice straw, para grass, cassava foliage, leucaena leaves, water hyacinth leaves) from two regions in Cambodia against faecal and urinary excretion of macro minerals by cattle. The analyses showed that Ca and P levels varied markedly between the different forages and that several of the commonly used forages in Cambodia have a mineral composition that does not cover the requirements of cattle. In an experimental study examining the effects of different levels of dietary supplementation with sun-dried cassava foliage (Manihot esculenta) total dry matter (DM) intake and nitrogen retention in cattle was found to increase with increasing intake of cassava foliage, but DM and fibre digestibility decreased. It was concluded that cassava foliage is a good Ca source which compensates for the low Ca content in rice straw and para grass, but P deficiency appears to be exaggerated in cattle with higher cassava intake. Two experiments to find an appropriate way of using sugar palm syrup when preserving para grass showed that applying at least 2% (fresh matter basis) sugar palm syrup to para grass at ensiling improved the fermentation quality of the resulting silage compared with a rice straw with rumen supplement diet. Rumen pH was slightly lower and feed conversion more efficient in cattle consuming silage. Para grass silage was a good source of digestible nitrogen

SCHOOL LEADERSHIP: THE EXERCISE OF LEGITIMATE POWER IN CAMBODIA

This research was undertaken in purpose of finding challenges with which the high school principals have encountered in using legitimate power, and strategies they have applied to exert it effectively. Methodologically, a holistic multiple-case design of qualitative research was employed because the study was conducted with principals and teachers who come from different schools, but the same units of analysis. 5 high school principals and 5 high school teachers from Kampong Thom province, Cambodia were purposively selected to get involved in writing answers of open-ended questions. Technically, NVivo 11 was utilized to analyse data. The results revealed that there have been a plethora of issues with which the principal have faced such as abusing power, power struggle, not obeying the rule, lack of motivation and professional consciousness, disagreement among colleagues, lax law, and low salary etc. Based on the participants’ experiences, to exercise legitimate power effectively, Cambodian principals have mostly adopted soft, hard, rational and bilateral power tactic in which relationship-oriented leadership style plays key roles.  Article visualizations

Self-adaptive fault diagnosis of roller bearings using infrared thermal images

Fault diagnosis of roller bearings in rotating machinery is of great significance to identify latent abnormalities and failures in industrial plants. This paper presents a new self-adaptive fault diagnosis system for different conditions of roller bearings using InfraRed Thermography (IRT). In the first stage of the proposed system, 2-Dimensional Discrete Wavelet Transform (2D-DWT) and Shannon entropy are applied respectively to decompose images and seek for the desired decomposition level of the approximation coefficients. After that, the histograms of selected coefficients are used as an input of the feature space selection method by using Genetic Algorithm (GA) and Nearest Neighbor (NN), for the purpose of selecting two salient features that can achieve the highest classification accuracy. The results have demonstrated that the proposed scheme can be employed effectively as an intelligent system for bearing fault diagnosis in rotating machinery

Earlier versus later start of antiretroviral therapy in HIV-infected adults with tuberculosis.

Tuberculosis remains an important cause of death among patients infected with the human immunodeficiency virus (HIV). Robust data are lacking with regard to the timing for the initiation of antiretroviral therapy (ART) in relation to the start of antituberculosis therapy

Needs-based assessment: a model for profiling, assisting, and empowering job seekers

Needs-based assessment (NBA) was developed in New Zealand to assess job seekers’ capacity, willingness, and opportunity to find work. This article outlines the development of NBA from its theoretical underpinnings, evidence from a longitudinal study and the development of an employment adviser–administered computerized profiling tool, and the provision of self-assessment and support tools. The authors argue that, with a rise in the number of unemployed job seekers and the long-term unemployed, demands for government resources with less resources available to satisfy those demands, and the widespread adoption of social and interactive media, it is timely to revisit an NBA approach to job seeker profiling and targeted intervention

Charmonium possibility of X(3872)

Properties of Regge trajectories for charmonium are studied. Possible interpretations and their implications to newly observed X(3872) are examined. It is found that the mass of X(3872) is consistent with the 1^{++} 2^3P_1 and the 2^{-+} 1^1D_2 charmonium states.Comment: 6 pages, 4 eps figures, 1 table, RevTex, published version in PLB with another titl

Livestock Domain: Effect of complete feed feeding level and morning glory on nursery and growing pig performance in Cambodia.

This data was created from the results of a controlled study to evaluate the effect of restricted feeding level and dietary morning glory on growth performance of nursery and growing pigs. This study was conducted on a total of 60 pigs with a starting weight of approximately 13 kg, in Cambodia. The study length will be 42 days conducted at a local producer facility. Four pigs were allotted to each pen based on starting body weight to achieve an equal starting weight across the 3 feeding comparisons.Thus, four pens of pigs will receive each ration (20 pigs per ration).This dataset was collected through research of the project "Integrated Horticulture Livestock Systems" lead by Kansas State University, in partnership with the Royal University of Agriculture, as a part of the Feed the Future Innovation Lab for Horticulture

Livestock Domain: Effect of soybean meal level in a rice bran-based diet on growing pig performance and economics in Cambodia.

This data was created from the results of a controlled study to evaluate the effect of increasing soybean meal in a rice bran-based diet on growth performance and economics of growing pigs. This study was conducted on a total of 60 growing pigs, in Cambodia. The study length was 52 days conducted at a local producer facility. Four pigs were allotted to each pen, based on starting body weight, to achieve an equal starting weight across the 4 feeding comparisons. Diet 1 has 3 replications (12 pigs) and diets 2, 3, and 4 have 4 replications (16 pigs per ration). The dataset includes formulas for diet formulations for each treatment group (a total of 4 treatments), data on Body Weight, Average Daily Feed, Average Daily Gain, and Feed Cost Ratio. This data was collected between April 6 and May 28, 2019. This data can be used by swine nutritionist, economists, and policy makers for developing recommendations for swine feeding. This dataset was collected through research of the project "Integrated Horticulture Livestock Systems" lead by Kansas State University, in partnership with the Royal University of Agriculture, as a part of the Feed the Future Innovation Lab for Horticulture.
