Obeidat, B.S.,Haddad, S.G.,Titi, H.H.,Abu Ishmais, M.A.,Telfah, B.T. Asian Australasian Association of Animal Productio 2012 Animal Bioscience Vol.25 No.8

Objective of this experiment was to evaluate the effect of partial substitution of barley grain with bread by-product (BB) on performance of Awassi ewes and their lambs. Forty Awassi ewes rearing single lambs were randomly allotted into four experimental diets containing various levels of BB. The experimental diets contained 0 (BB0), 10 (BB10), 15 (BB15), and 20% (BB20) of BB on dietary dry matter (DM). The study lasted for eight weeks, in which the first week was used as an adaptation period and seven weeks of data collection. Ewes and their lambs were penned individually where they were fed their lactating diets ad libitum. Ewes and lambs body weights were measured at the beginning and at the end of the experiment. However, milk production and composition were evaluated biweekly. Feeding BB had no effect (p>0.05) on dry matter (DM), organic matter (OM), and crude protein (CP) intakes. However, neutral detergent fiber (NDF) intake was the lowest (p<0.05) for the BB20 and BB15 diets followed to BB10 diet (i.e., 640, 677, 772 g/d, respectively) while the highest NDF intake was for the BB0 diet (i.e., 825 g/d). Similarly, NDF intake decreased linearly (p<0.001) as the BB content increased. Acid detergent fiber (ADF) intake was highest (p<0.05) for the BB0 and BB10 diets (425 and 416 g/d, respectively) followed by the BB15 and BB20 diets (359 and 342 g/d, respectively). Moreover, a linear (p<0.001), quadratic (p = 0.04), and cubic (p = 0.04) effects were observed in ADF intake among diets. Nutrient digestibility was similar among different diets. Bread by-product had no effect (p>0.05) on ewes body weight change and on lamb performance (i.e., weaning body weight and average daily gain). Similarly, no differences (p>0.05) were observed either in milk production or composition by the BB substitution. Inclusion of BB reduced feed cost by 9, 14, and 18% for the BB10, BB15, and BB20 diets, respectively. No differences were observed in milk efficiency (DM intake: milk production; p>0.05) among diets. However, cost of milk production ($US/kg milk) was the lowest (p<0.05) in the diet containing BB20. Results of the present study indicate that feeding bread by-product up to 20% of the diet DM had no effect on performance of Awassi ewes and their lambs and reduced feed cost.

Obeidat, Belal S.,Abdullah, Abdullah Y.,Awawdeh, Mofleh S.,Kridli, Rami T.,Titi, Hosam H.,Qudsieh, Rasha I. Asian Australasian Association of Animal Productio 2008 Animal Bioscience Vol.21 No.6

The objective of this study was to evaluate the effects of ruminally-protected methionine supplementation (0, 7, or 14 g/head/d) on nutrient intake, digestibility, growth performance, carcass, and meat characteristics of Awassi ram lambs fed finishing diets. Twenty four Awassi ram lambs ($16.8{\pm}1.17kg$ body weight) were randomly assigned to 3 treatment diets (8 lambs/treatment) and housed in individual pens. Lambs were given an adaptation period of 7 days before the intensive feeding period that lasted for 86 days. On day 74 of the trial, a digestibility experiment was performed. At the end of the trial (d 86), all lambs were slaughtered to evaluate carcass characteristics and meat quality. Increasing the level of methionine supplementation did not improve (p>0.05) performance nor feed conversion ratio. Nutrient intake and digestibilities were not influenced (p>0.05) by methionine supplementation. There were no differences in final weight, hot and cold carcass weights, dressing percentages or any of the measured non-carcass components. Tissues and fat depth measurements together with all meat quality attributes measured on longissimus muscle of the loin cut were not affected by methionine supplementation. The only meat quality parameters affected were redness (a*) and the hue angle being higher for the control group (p<0.05). These results suggest that methionine supplementation is not likely to produce any production benefits in nutrient digestibilities, performance or carcass characteristics of ram lambs fed a high performance diet.

Effect of Feeding Sesame Hull on Growth Performance, Nutrient Digestibility, and Carcass Characteristics of Black Goat Kids

Obeidat, Belal S.,Gharaybeh, Firas F. Asian Australasian Association of Animal Productio 2011 Animal Bioscience Vol.24 No.2

An experiment was conducted to evaluate the effect of replacing barley and soybean meal in finishing diets with sesame hull (SH) on growth performance, digestibility, and carcass characteristics of Black goat kids. Twenty-one Black goat kids were assigned randomly to 0%, 10%, or 20% SH diets (7/diet). The study lasted for 63 d. Intakes of dry matter (DM), organic matter (OM), and crude protein (CP) of kids fed the 10% diet were greater (p<0.05) than for the 0% and 20% SH diets (p<0.10). Neutral detergent fiber (NDF) and acid detergent fiber (ADF) intakes were highest (p<0.05) for kids fed the 10% SH diet when compared to 0% and 20% SH diets. Ether extract (EE) intake was greater (p<0.05) for kids fed 10% and 20% SH diets when compared to 0% SH. Digestibilities of DM, OM, CP, NDF, and ADF were similar among all diets. However, sesame hull inclusion increased (p<0.05) EE digestibility. Final body weight, total gain, average daily gain (ADG), and feed conversion ratio were comparable among all diets. Cost of gain was lower (p<0.05) in kids fed 20% SH than the 0% SH diet, while there was no difference between the 10% SH diet and the other two diets. Dressing percentage, hot and cold carcass weights, non-carcass components, carcass cut weights, and meat quality parameters were not influenced by SH. Total fat percentage in the leg was greater (p<0.05) on 0% SH than on the 10% SH diet. Results of this study demonstrated that inclusion of sesame hull at levels of 10 or 20% did not influence the performance of Black goat kids, but the cost of gain was lower.

Rethinking Anti-tobacco Health Education in an Eastern Mediterranean Country with Growing Tobacco Use

Obeidat, NA,Ayub, HS,Shtaiwi, AS,Hawari, FI Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.2

Background: In Jordan, a developing country with a high tobacco burden and where roughly 40% of cancers are tobacco-related, limited knowledge exists on public awareness regarding tobacco. This is a hindrance for experts seeking to strengthen anti-tobacco health promotion and counter growing tobacco use. We sought to evaluate public awareness regarding tobacco; to gauge exposure to anti-tobacco public messages; and to draw attention to the lay public's informational needs. Materials and Methods: A cross-sectional survey of lay public in the capital, Amman, capturing knowledge regarding tobacco harms and anti-tobacco laws, perceptions regarding tobacco use and control, and exposure to and recall of anti-tobacco messages, was conducted. Statistics on perceptions were generated and analyzed by smoking status and sociodemographic factors. Multivariate regression was performed to estimate independent associations of smoking and sociodemographic factors with knowledge. Results: Of 1,169 respondents, 17.8% could recall specific anti-tobacco messages. With regard to knowledge, despite high proportions of respondents exhibiting knowledge for individual statements regarding tobacco health harms, variables capturing breadth of knowledge showed that much lower proportions could correctly identify all the listed health harms of tobacco, and all listed Jordanian anti-tobacco regulations (47.5% and 36.2%, respectively). On multivariate analysis, breadth of knowledge varied by smoking status, age and educational level. Conclusions: There is need for more salient, evocative and multi-faceted anti-tobacco messages in Jordan, tailored to subgroups, given detected variability in knowledge across smoking status and sociodemographic characteristics.

Obeidat, Ahmad A.,Ahmad, Mousa N.,Haddad, Fares H.,Azzeh, Firas S. The Korean Nutrition Society 2016 Nutrition Research and Practice Vol.10 No.4

BACKGROUND/OBJECTIVES: Metabolic syndrome (MetS) is a set of interrelated metabolic risk factors that increase the risk of cardiovascular morbidity and mortality. Studies regarding the specificity and sensitivity of serum levels of leptin and uric acid as predictors of MetS are limited. The aim of this study was to evaluate the serum levels of leptin and uric acid in terms of their specificity and sensitivity as predictors of MetS in the studied Jordanian group. SUBJECTS/METHODS: In this cross sectional study, 630 adult subjects (308 men and 322 women) were recruited from the King Hussein Medical Center (Amman, Jordan). The diagnosis of MetS was made according to the 2005 International Diabetes Federation criteria. Receiver operating characteristic curves were used to determine the efficacy of serum levels of leptin and uric acid as predictors of MetS in the studied Jordanian group. RESULTS: Study results showed that for identification of subjects with MetS risk, area under the curve (AUC) for leptin was 0.721 and 0.683 in men and women, respectively. Serum uric acid levels in men showed no significant association with any MetS risk factors and no significant AUC, while uric acid AUC was 0.706 in women. CONCLUSION: Serum leptin levels can be useful biomarkers for evaluation of the risk of MetS independent of baseline obesity in both men and women. On the other hand, serum uric acid levels predicted the risk of MetS only in women.

The Effects of Intellectual Capital and Financial Leverage on Evaluating Market Performance

OBEIDAT, Samer,AL-TAMIMI, Khaled,HAJJAT, Emad Korea Distribution Science Association 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.3

This study aimed to identify the key factors that affect the financial market performance (Price-Earnings Model) through a sample of 35 public shareholding industrial companies on the Amman Stock Exchange for the period 2010-2019, using statistical models and methods, such as the Simple Linear Regression Model, Correlation Coefficient, and dispersion board. The study results showed the nonexistence of a statistically significant effect between the intellectual capital and market value added (MVA) and market performance. Results also showed a statistically significant positive effect between financial leverage (FL) and the market performance, where the interpreted variation reached 64%. It showed from the analysis results that the relationship between (MVA) and market performance (P/E) agrees with the study hypotheses, while the result related to (FL) disagrees with the study hypotheses. The study recommends that public shareholding industrial companies should focus more on intellectual capital and show its value in the annual financial statements and reports, and those companies that have high profitability and the chance to hold gains and profits should rely less on debt and more on retained earnings, due to the high risk of debt and in line with the present unstable circumstances in Jordan, especially in light of the global Covid-19 crisis.

A Cooperative Multiagent System for Enhancing Smart Grid Performance

Mohammad A Obeidat International Journal of Computer ScienceNetwork S 2023 International journal of computer science and netw Vol.23 No.2

Sharing power data between electrical power grids is crucial in energy management. The multi-agent approach has been applied in various applications to improve the development of complex systems by making them both independent and collaborative. The smart grid is one of the most intricate systems that requires a higher level of independence, reliability, protection, and adaptability to user requests. In this paper, a multi-agent system is utilized to share knowledge and tackle challenges in smart grids. The shared information is used to make decisions that aid in power distribution management within the grid and with other networks. The proposed multi-agent mechanism improves the reliability of the power system by providing the necessary information at critical times. The results indicate that the multi-agent system operates efficiently and promptly, making it a highly promising candidate for smart grid management.

Postural Modeling of Palletizing Workers via Simulation based on RULA, NMQ, and NIOSH

Mohammed Said Obeidat,Diana Bashar Abbasi,Khalid Mohammad Alzoubi,Linda A. Alyahya 대한산업공학회 2024 Industrial Engineeering & Management Systems Vol.23 No.1

The risk factors in palletizing were analyzed using CATIA V5 software, considering the Nordic Musculoskeletal Questionnaire (NMQ), Rapid Upper Limb Assessment (RULA), and NIOSH. The NMQ showed a high prevalence of Musculoskeletal Disorders of 58.3% within 12 months and 33.3% within 7 days. The RULA score was 7, however, when using an assistive device in palletizing and wrapping, the RULA became 3 at low and medium heights lifting, and 4 at the highest level of the loaded pallet lifting, and when lifting at the elbow height. NIOSH results while using the assistive device showed a lifting index of 0.3 at origin, and 0.4 at destination. The paper introduces a new assistive device to industry, which could help reduce the exposure to physical loads among palletizing workers, using the three studied tools: The NMQ, RULA, and NIOSH.
