This book, therefore, provides an insight into the use of dietary Zn to induce molt and its effect on subsequent production cycles in laying hens. We have used feed withdrawal, photoperiodic alterations and the use of high dietary zinc (Zn) as an effective method to induce molt in laying hens. Keeping in view the significance of eggs in the human nutrition, the current study was undertaken to determine the impact of molting on immunity of birds, egg quality characteristics and immunohistochemical changes in the pars distalis after induction of molt in laying hens. There were deficiency in the studies of induced molting related to immune system and pituitary cells function in different hormonal secretions. With the increase in economic pressure in world there is more need of the recycling of layers through induced molting. The study will also help to enable the poultry farmers and researchers to formulate a diet for molt induction in laying hens because the traditional fast induced molting method is under criticism by the animal rights associations.

По стопам еврейских работорговцев
Поскольку у евреев вроде бы не принято приносить усопшим на могилы подношения и деньги, то возникло подозрение, что делают это неевреи. Г-н Мадуро сказал мне, что это делают вудуисты, которые полагают, что духи евреев обладают особенно ценными качествами, потому они проводят свои обряды именно на еврейском, а не на других кладбищах. По его словам, делают это не местные потомки рабов, а переселенцы с острова Гаити. Я стал искать в интернете информацию об особом отношении вудуистов к еврейским кладбищам, но не нашел ничего, кроме статьи Джудит Файн, которая ссылается на того же самого моего информанта, г-на Рене Мадуро. Вот что она пишет: "I fro of o e of he ombs, o he grou d, here was a bowl made from a gourd wi h a egg i side. Maduro explai ed ha " his is par of voodoo ri uals belo gi g o ew immigra s from o her Caribbea isla ds. hey co sider he Jewish soul a good soul a d wa o have heir prayers i our ceme ery." Все это весьма любопытно и требует выяснения, известно, что у местных темнокожих островитян (а не пришельцев с Гаити) существуют разнообразные поверья о духах с еврейского кладбища.
|Metal Induced Crystallization and Polysilicon Thin Film Transistors. Novel technologies of crystallization and post-annealing Книга по Требованию Bo Z. |
A few technologies are presented in this monograph, which improve the quality of MIC polysilicon film and hence the performance of TFTs built on. Amelioration of MIC processes has been made to produce high performance polysilicon TFTs using solution based MIC (SMIC) and defined-grain MIC (DG-MIC) methods.

|A Predictive Methodology for Mapping Potential Mining Induced Rock Falls Geographical Information Systems and Mining Impacts. Книга по Требованию |
The approach is developed using a GIS-based weight-of-evidence methodology with the following characteristics: 1)A data driven technique for impact assessment during the preliminary stages of mine design when the field data is limited; 2)Identification of pertinent controlling factors in rockfall occurrence phenomena; 3)The analysis of the level of influence for each controlling factor, weighting and combining evidential factors using the weight-of-evidence method; 4)The mapping of the probability of a rockfall occurrence within the area of interest. Application of the methodology was tested for a case study in Australia where the methodology was used to evaluate and compare impact of two different proposed mine layouts on the present cliff lines within the mining area. The book describes a quantitative spatial methodology for the mapping of potential mine subsidence impacts on cliff-lines using a Geographical Information System (GIS). The ability to assess the potential mine subsidence impact undoubtedly can be valuable for subsidence management plans and any decision-making process carried out prior to mining.
|Pollution and Reproductive Damage. Pollution induced cell-death and reproductive damage in fish and mammals Книга по Требованию Mozhgan S. |
Here we offer first evidence that petrochemical contaminants induce apoptosis in highly proliferating reproductive, hematopoietic, and immune (thymus, bone marrow, and spleen) tissue of small mammals living on contaminated sites; we also show that aquatic pollution effects on reproductive fitness can be monitored using in vitro cultures of fish eggs.

|Geomagnetically Induced Current Книга по Требованию Frederic P. M. |
During space weather events electric current systems in the magnetosphere and ionosphere experience large spatiotemporal variations reflected also in the variations of the Earth' s geomagnetic field. These variations induce currents in conductors operated at the surface of Earth. Electric transmission grids and buried pipelines are common examples of such conductor systems. GIC can cause problems, such as increased corrosion of pipeline steel and damaged high-voltage power transformers. GIC are one possible consequence of geomagnetic storms, which may also affect geophysical exploration surveys and oil and gas drilling operations. Geomagnetically induced currents, affecting the normal operation of long technological conductor systems, are a manifestation at ground level of space weather.
|Effect of Plant Extracts on RNA Expression Profiles. Expression Profiles of the Insulin 2 Gene in Pancreatic Cells of Streptozotocin-Induced Diabetic Rats Книга по Требованию Ruzaidi A.M.M. |
This study investigated the effect of selected plant extracts on the Insulin 2 gene expression profile against STZ- induced pancreatic cell damages. M. charantia extract showed the highest value of total phenolic content, antioxidant activity and total flavanoid content compared to M. citrifolia and P. speciosa extracts. Expression of both GAPDH as the reference gene and Ins2 gene as the target gene was measured by SYBR Green I fluorescence; melting curves and agarose gel electrophoresis were used to verify the specificity of gene (Ins2) for diabetic rats treated with M. charantia extracts expressing fold differences of 32 fold expression compare to the diabetic control rats only.
