The Effect of Energy Level of Feeding on Daily Gain, Blood Glucose and Urea on Madura Cattle
This study was aimed to evaluate the effect of dietary energy level on daily gain of Madura cattle and their blood metabolites (glucose and blood urea). Twelve (12) male Madura cattle aged at 2 years old, 156.27+6.92 kg (CV 4.43%) of body weight were used in this study which was assigned to completely randomized design for three feeding treatments (low, middle and high energy contents) and four replications. The daily gain was measured for 90 days, while the blood metabolites were measured at the middle of experiment. Results showed that dietary energy levels did not affect (P>0.05) average daily gain, dry matter intake, dry matter digestibility, energy intake and feed conversion ratio. Blood glucose and blood urea concentration were ranged at 67-75 and 35-50 mg/dL, respectively, while feed energy efficiency reached 0.145 MJ/g ADG. In conclusion, high-level energy could not provide better performance in Madura cattle because of a limitation factor on the DMI
Conditioned media and DMSO enhance the cryopreservation of bovine adipose tissue-derived mesenchymal stem cells
Mesenchymal stem cells derived from adipose tissue (AD-MSCs) show great potential for repro ductive biotechnology in the livestock sector. However, enzyme-based isolation of MSCs is expensive and time-consuming, so it is still rarely done, especially for applications in the livestock sector in de veloping countries. So, MSCs must be cryopreserved with an efficient cryoprotective agent to be stored and reproduced in various laboratories after isolation. This study was aimed to optimize the cryopreser vation media for adipose-derived MSCs in cattle. This study evaluated the viability, proliferation, and morphology of AD-MSCs. The results of this study indicate that a combination of 10% DMSO, 45% DMEM, and 45% conditioned media significantly improves post-thaw viability, proliferation, and sur vival as compared to other mediums. Furthermore, AD-MSCs cryopreserved in this medium exhibit similar morphology as fresh cells. These findings suggest that the optimized cryopreservation medium can enhance the quality and safety of AD-MSCs for clinical applications in the livestock industry
Constructing and Multilateralizing the Regional Comprehensive Economic Partnership: An Asian Perspective
In May 2013 the ASEAN+6 countries began to negotiate the Regional Comprehensive Economic Partnership (RCEP). The objective of this paper is to analyze the feasibility of constructing such a region-wide agreement and to examine ways to multilateralize it. The paper first reviews free trade agreement (FTA) developments, and discusses the characteristics and motives of FTAs in East Asia. It then analyzes the contents of major plurilateral FTAs in East Asia, that is ASEAN's five FTAs each with the People's Republic of China, Japan, the Republic of Korea, India, and Australia/New Zealand, which are considered as a base for a region-wide FTA. Finally, the paper examines the feasibility of the RCEP by consolidating the ASEAN+1 FTAs and discusses the possible ways to multilateralize the RCEP
Special and Differential Treatment in the WTO: Why, When and How?
This paper analyses to which extent domestic institutions affect trade flows. We use two complementary approaches, one focusing on the size of total trade flows and one focusing on bilateral trade patterns (gravity equation). Besides, we control for two other domestic policy variables: trade policy and domestic infrastructure. We find that the quality of institutions has a positive and significant impact on a country's level of openness. Domestic tariffs have no statistically significant impact on their own, but do affect total trade flows when combined with good institutions. Domestic institutions also have a positive and significant impact on bilateral trade flows, but the parameter of our institution variables is reduced by almost a half and may turn insignificant when the quality of domestic infrastructure is included in the regression
The global burden of typhoid and parathypoid fevers: a systematic analyses for the Global Burden of Disease Study 2017
Background Efforts to quantify the global burden of enteric fever are valuable for understanding the health lost and
the large-scale spatial distribution of the disease. We present the estimates of typhoid and paratyphoid fever burden
from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017, and the approach taken to
produce them.
Methods For this systematic analysis we broke down the relative contributions of typhoid and paratyphoid fevers by
country, year, and age, and analysed trends in incidence and mortality. We modelled the combined incidence of
typhoid and paratyphoid fevers and split these total cases proportionally between typhoid and paratyphoid fevers
using aetiological proportion models. We estimated deaths using vital registration data for countries with sufficiently
high data completeness and using a natural history approach for other locations. We also estimated disability-adjusted
life-years (DALYs) for typhoid and paratyphoid fevers.
Findings Globally, 14·3 million (95% uncertainty interval [UI] 12·5–16·3) cases of typhoid and paratyphoid
fevers occurred in 2017, a 44·6% (42·2–47·0) decline from 25·9 million (22·0–29·9) in 1990. Age-standardised
incidence rates declined by 54·9% (53·4–56·5), from 439·2 (376·7–507·7) per 100000 person-years in 1990, to
197·8 (172·0–226·2) per 100 000 person-years in 2017. In 2017, Salmonella enterica serotype Typhi caused
76·3% (71·8–80·5) of cases of enteric fever. We estimated a global case fatality of 0·95% (0·54–1·53) in 2017, with
higher case fatality estimates among children and older adults, and among those living in lower-income countries.
We therefore estimated 135·9 thousand (76·9–218·9) deaths from typhoid and paratyphoid fever globally in 2017, a
41·0% (33·6–48·3) decline from 230·5 thousand (131·2–372·6) in 1990. Overall, typhoid and paratyphoid fevers were
responsible for 9·8 million (5·6–15·8) DALYs in 2017, down 43·0% (35·5–50·6) from 17·2 million (9·9–27·8) DALYs
in 1990.
Interpretation Despite notable progress, typhoid and paratyphoid fevers remain major causes of disability and death,
with billions of people likely to be exposed to the pathogens. Although improvements in water and sanitation remain
essential, increased vaccine use (including with typhoid conjugate vaccines that are effective in infants and young
children and protective for longer periods) and improved data and surveillance to inform vaccine rollout are likely to
drive the greatest improvements in the global burden of the diseas
Middle East - North Africa and the millennium development goals : implications for German development cooperation
Closed-loop controlled combustion is a promising technique to improve the overall performance of internal combustion engines and Diesel engines in particular. In order for this technique to be implemented some form of feedback from the combustion process is required. The feedback signal is processed and from it combustionrelated parameters are computed. These parameters are then fed to a control process which drives a series of outputs (e.g. injection timing in Diesel engines) to control their values. This paper’s focus lies on the processing and computation that is needed on the feedback signal before this is ready to be fed to the control process as well as on the electronics necessary to support it. A number of feedback alternatives are briefly discussed and for one of them, the in-cylinder pressure sensor, the CA50 (crank angle in which the integrated heat release curve reaches its 50% value) and the IMEP (Indicated Mean Effective Pressure) are identified as two potential control variables. The hardware architecture of a system capable of calculating both of them on-line is proposed and necessary feasibility size and speed considerations are made by implementing critical blocks in VHDL targeting a flash-based Actel ProASIC3 automotive-grade FPGA
