Process development of wool fabric

Process development of wool fabric

Автор: Santanu Basak

Wool fibre has a so-called skin–core structure. In this structure, the inner cortex is hydrophilic in nature due to the large number of polar groups contained in the polypeptide chains of the cortex. On the other hand, the outer surface of wool fibre is hydrophobic due to the presence of a high degree of disulphide cross-linkages in the cuticle and a film of fatty acids on the fibre surface which acts as a surface barrier against diffusion into wool fibres . Many chemical methods have been developed for modifying the wool fibre surface, such as chlorination and polymer deposition but these processes are often very harsh and modify the bulk properties, besides creating effluent problems . As a result of increasing environmental awareness and tougher government legislation on effluent discharge around the world, alternative methods with lower environment impact need to be explored and one such method is surface modification by physical means. Different types of radiation techniques have…

Rebuilding Sustainable Urban Livelihoods

Rebuilding Sustainable Urban Livelihoods

Автор: Blessing Gweshengwe

Considering the degree of urban livelihoods deterioration in the Sub –Saharan African countries like Zimbabwe due to socio-economic and political factors, the study was undertaken to explore the roles of Non-Governmental Organisations (NGOs) on rebuilding sustainable urban livelihoods. This study was conducted in Mbare, one of the poverty stricken high density residential areas of Harare in Zimbabwe. Oxfam GB and ZimPro joint initiative’s programmes and projects were the ones examined during the study.

Техногенное загрязнение поверхностных и подземных вод города Риддер

Техногенное загрязнение поверхностных и подземных вод города Риддер

Автор: Наталья Гуслякова

Водные ресурсы г. Риддер испытывают интенсивную нагрузку по загрязнению токсичными компонентами промышленных предприятий горно-добывающей и перерабатывающей отраслей. Эти предприятия расположены в зоне наиболее густой речной сети. Решение проблемы загрязнения поверхностных и подземных вод является одной из приоритетных задач охраны окружающей среды в городе. В книге рассмотрены характеристика отвалов и влияние отходов промышленных предприятий на водные ресурсы г. Риддер, выявлена динамика загрязнения поверхностных вод за последние 6 лет, а также даны выводы и рекомендации по улучшению состояния водных объектов города. Проведен анализ существующего положения очистки вод Тишинского рудника РГОК ТОО «Казцинк» г. Риддер. Выполнена разработка мероприятий по улучшению систем очистки шахтных и дренажных вод из-под отвала №2, так как существующее воздействие породного отвала на водные ресурсы оценивается как катастрофическое. Дана оценка снижения экономического ущерба от загрязнения…

Hormonal Regulation of Mouse Lactogenesis

Hormonal Regulation of Mouse Lactogenesis

Автор: Maurice Ling

Advances in biological research in the post-genomic era had resulted in a large number of research publications and data that far exceeds a scientist’s ability to keep abreast. This work focused on the hormonal regulation of mouse lactogenesis as a case study, for the development of computational methods with the potential to survey large volumes of literature for the current state of knowledge, which can be used to screen against experimental data. This work found a set of expressionally correlated genes that are not mentioned in the literature — presenting novel areas of study. As keeping abreast with knowledge is an increasingly crucial part of the life of a research scientist, the author presents a changing face of biological research — from survey-hypothesize-research-evaluate to survey-hypothesize-research / knowledge update-evaluate.

Advances in Cashew Entomology

Advances in Cashew Entomology

Автор: Sudarshan Chakraborti

This volume has detailed coverage of the important insect pests of cashew. The mirid bug, Helopeltis sp., is a well-established key pest irrespective of the zoo-geographical situations and is also a serious future threat for the non-occurring zones. Other important foliage pests like webbers, shoot tip caterpillars, thrips, leaf miners and apple and nut borers have also been adequately covered. Stem and root borers form a very serious pest-complex and hence, extensive information on this group have been synthesized. Natural enemies play an important role in a rational pest management strategy; those of cashew ecosystem have been covered in great detail. Pollinators play a defining role in cashew production systems but are adversely affected by synthetic inorganic pesticides. An entire sub-section has been devoted to this crucial biotic component. Insect infestation of stored raw nuts lead to both qualitative and quantitative degradation, resulting in poor kernel recovery and special…
