Effect of milling speed on the quality and storage stability of maize flour

This work was undertaken to evaluate the effect of milling speed on the quality and shelf life of maize flour. Maize flour was prepared using low speed mini flour mill at 75 and 115 rpm and the results were compared with the flour prepared by commercial flour mill on the basis of recovery of flour, rise in temperature of flour, time taken, particle size distribution and changes in different quality parameters during storage. It was observed from the analysis that the recovery of flour was highest (95.26%) at 75 rpm speed although the time taken was more i.e. 27.27 minutes, but the rise in temperature during milling was very less (12.240C) as compared to commercial mill the temperature rose up to 31.120C. It was noted that the maize flour prepared at low speed was light yellow in color as compared to higher rpm which was dark yellow. The maize flour prepared at 75 rpm can be stored in low density polyethylene LDPE packaging material of (200 gauge) for two months without change in quality parameters. It was observed that the moisture content, protein content, fat content, alcoholic acidity and carbohydrates was significantly affected by storage time, packaging material and milling speed at P<0.05. Therefore, at low speed the storage stability as well as nutritional properties of the flour can be enhanced. The improved shelf life of flour can result in better marketability

Taxonomic revision of the Genus Pieris Schrank (Lepidoptera: Pieridae) from India

The genus Pieris Schrank popularly called as garden whites are economically important species of family Pireridae, comprise 35 species world over and in India is represented by nine species. In the present manuscript, six species of genus Pieris Schrank i.e., i.e. P. brassicae (Linnaeus), P. canidia (Linnaeus),  P. deota (de Niceville),  P. extensa  Poujade, P. melete Menetries and P. rapae (Linnaeus) have been treated taxonomically from India. Besides studying morphological characters, their male and female genitalia have been described in details and illustrated for the first time. The diagnosis of the genus and key to species has been updated using genitalic attributes. In the study of genitalia, it has been observed that in the male genitalia of the genus Pieris the uncus is undivided and aedeagus is short and thick, whereas in the female genitalia the signum is bifid and appendix bursae are well developed. In the present work, the male genitalia of scheduled species P. deota has been studied and illustrated for the first time. The male and female genitalia of dry season forms and wet season forms of species P. melete, and the subspecies and polymorphic forms of species P. canidia have been studied and compared. It has been observed that in all forms there were no genitalic variations within the species

ПРИМЕНЕНИЕ 1-, 3- И 6-МЕСЯЧНЫХ ЛЕКАРСТВЕННЫХ ДЕПО-ФОРМ ЛЕЙПРОРЕЛИНА АЦЕТАТА В ГОРМОНАЛЬНОЙ ТЕРАПИИ РАКА ПРЕДСТАТЕЛЬНОЙ ЖЕЛЕЗЫ В 9 ЕВРОПЕЙСКИХ СТРАНАХ: ОБЗОР ДОКАЗАТЕЛЬСТВ И ЭКОНОМИЧЕСКАЯ ОЦЕНКА

Применение 1-, 3- и 6-месячных лекарственных депо-форм лейпрорелина ацетата в гормональной терапии рака предстательной железы в 9 европейских странах: обзор доказательств и экономическая оценка.Введение. Лейпрорелин – хорошо известный агонист лютеинизирующего гормона рилизинг-гормона, используемый в терапии рака предстательной железы (РПЖ) первой линии. В связи с тем, что использование различных лекарственных форм и режимов дозирования влечет определенные материальные расходы, целью нашего исследования являлась оценка эффективности, безопасности и стоимости применения различных лекарственных форм и режимов дозирования в 9 европейских странах: Австрии, Бельгии, Чешской Республике, Венгрии, Италии, Латвии, Нидерландах, Польше, Португалии.Материалы и методы. В результате поиска в базах данных было выявлено 13 клинических исследований с применением лейпрорелина, применяемого в формах для введения 1 раз в месяц (1 М), 1 раз в 3 мес (3 М) и 1 раз в 6 мес (6 М). По всем 3 формам сравнивали только те данные о применении лейпрорелина с системой доставки Атригель, которые характеризовались одинаковой эффективностью, безопасностью и соблюдением предписанного режима терапии. Был проведен анализ минимизации затрат с учетом расходов на лечение препаратом Элигард, консультации специалистов, а также диагностику сроком до 12 мес последующего наблюдения. Анализ был проведен для органов государственного здравоохранения.Результаты. В выборке пациентов «все пациенты, начавшие получать лечение», уровень тестостерона которых составил ≤ 50 нг/дл после лечения препаратом Элигард в формах 1 M (93,3 %), 3 М (98,3 %) и 6 М (97,3 %), существенного различия не наблюдалось (p > 0,05). Также сопоставимыми были профили нежелательных явлений этих 3 форм. В целом форма 6 М была наименее дорогостоящей; средние общие годовые затраты составили от 788 евро (Бельгия) до 1839 евро (Португалия). Вариант использования формы 3 M был более дорогостоящим, затраты на него превышали таковые при применении формы 6 М на 2,5 % (Венгрия) – 37,6 % (Бельгия); использование формы 1 М было наиболее дорогостоящим при увеличении расходов на 15,5 и 151,6 % в сравнении с формой 6 М для этих стран соответственно. Форма 3 M была дешевле в сравнении с формой 1 М на 11,2–45,3 %. Общая сумма затрат была связана с частотой визитов для введения препарата и проведения мониторинга. Для лечения с применением формы 1 M потребовалось 12 визитов, формы 3 M – от 4,4 до 4,8 визита и формы 6 М – от 2,1 до 2,3 визита. До 50 % дополнительных визитов может финансироваться из сэкономленных средств, полученных в результате перевода соответствующих пациентов с форм 1 М и 3 М на форму 6 М. Полученные результаты одномерных и вероятностных анализов чувствительности были стабильными.Вывод. Формы препарата Элигард обеспечивают сопоставимую эффективность и безопасность, однако различные режимы дозирования препарата требуют различной частоты посещения лечебного учреждения пациентами. Лекарственная форма 6 М обеспечивает наибольшую экономию средств и должна рассматриваться в качестве препарата выбора для лечения соответствующих пациентов в Европе

Conservation Agriculture and Scale of Appropriate Agricultural Mechanization in Smallholder Systems

This manual has focused on the need to amplify and accelerate adoption of conservation agriculture (CA) practices that enable productivity increases on a sustainable basis. The development of the training manual on ‘Conservation Agriculture and Scale Appropriate Agricultural Mechanization in Smallholder Systems’ is an outcome of the series of advanced training programs on Conservation Agriculture over past one decade. The objectives of this training manual are; (1) To foster capacity building of researchers, extension workers, farmers and machinery manufacturers to promote CA in Asia and Africa; and (2) To raise the awareness of policy planners and decision makers to develop a strategic plan for the development of CA and agricultural mechanization in the developing world. There are several initiatives in South Asia and Africa to promote CA practices as environment-friendly and alternative to conventional agriculture. However, little has been done to document the CA practices or even lessons learnt from these initiatives. Farmers today still lack access to information on CA practices. This is a comprehensive manual that explains in a step by step easy to follow manner on how to implement CA by smallholders in Asia and Africa. It explains what CA is, and why it is important, how to use CA principles in the field and highlights the issues and challenges that researchers, farmers, machinery manufacturers and service providers may encounter when they adopt and adapt CA practices. This manual aims to be a valuable reference and is intended for use by researchers, agricultural extension officers/workers, farmers, machinery manufacturers and service providers to promote CA in Asia and Africa for increasing productivity and reducing poverty. It is written in clear, easy-to-understand language, and is illustrated with numerous figures and tables. It is not intended to cover the subject of conservation agriculture comprehensively but to provide an overview of the principles and practices. Indeed, as the training draws from many distinct disciplines, it is unlikely that any one person will have the necessary technical skills to cover the complete course content. Manual also focuses on two crucial aspects: the provision of farm mechanization services as a viable business opportunity for entrepreneurs, and the essential criteria of raising productivity in an environmentally sensitive and responsible way. This manual is also designed to serve as source of information for custom hire service providers – whether already in the business or intending to start their own hire service business – with skills and competencies in both the technical and the management aspects of the small-scale mechanization business. CA to reach smallholder farmers needed the publication of simplified technical manual. This manual contains useful technical information on CA practices that offer practical answers to questions normally asked by farmers of what, why, how

Multivariable averaging level control

This thesis studies the multivariable averaging level control problem by developing and comparing various controller design techniques. Due to obvious safety and economic considerations, the level of a surge tank must never be allowed to overflow or become empty, while the flow rate constraints must be satisfied. Hence, the main emphasis of the thesis is on the study of constrained controller design techniques. Multivariable design techniques such as decentralized, decoupled and full multivariable control are studied. The special structure of the system model allows for a constant decoupling matrix over all frequencies. This significantly simplifies the decoupled controller design. In full multivariable control, constrained Model Based Predictive Control (MPC) is utilized as it is able to naturally incorporate system constraints. Various cost function formulations which lead to either Quadratic or Linear Programming optimizations are presented and compared. The drawback of incorporating a terminal constraint set in MPC design is also studied. A novel mixed norm MPC algorithm that removes the requirement for using a terminal constraint set is proposed. MPC based on QP optimization is shown to provide the best results. The nonsmooth behaviour of MPC under LP optimization is also discussed. Finally, the practicality of some computationally-friendly techniques is assessed on a lab scale two-tank apparatus. The control algorithms are implemented in real-time using MatLab and dSpace.Applied Science, Faculty ofElectrical and Computer Engineering, Department ofGraduat

Effect of glycerine and water emulsion of diesel-biodiesel blends on engine performance and emissions with EGR

The globally rising temperatures and its impact on our ecosystem and earth’s natural processes have raised an environmental concern worldwide. The pollution caused due to the burning of fossil fuels has resulted in climate change, thus, compelling the researchers to look for eco-friendly fuels. Biodiesel derived from biomass have emerged recently as a possible fuel due to their role in decreasing CO emissions. However, the excessive production of biodiesel has raised a disposal concern for its by-product glycerine and higher NOx emissions produced through its use has initiated the need to look for other alternative fuels. In the present study, a systematic comparison was performed with multiple blends of diesel-biodiesel and their glycerine emulsions to compare it with water emulsion and investigate the performance and emissions of the related fuels along with the EGR system. All fuel blends and their emulsions were tested on a light-duty and heavy-duty engine. Hydrophilic-lipophilic balance (HLB) was formulated using suitable surfactants to attain the desired stability for various emulsion fuels. Emulsion stability, mean particle droplet size, fuel properties, engine performance, and emissions were observed. It was concluded that brake-specific fuel consumption (BSFC) and brake-thermal efficiency (BTE) increased with the increase in biodiesel and water-glycerine concentration. For emissions, the rise in CO and HC were noted but reductions in exhaust gas temperature, smoke and NOx were observed with emulsion fuels without EGR. Also, there was a significant decrease in smoke (approximately 80%) with increased concentration of glycerine at 3000 rpm, at high load. With the use of EGR, an increase in BSFC and decrease in BTE was observed. Additionally, EGR was seen to increase smoke, CO and HC emissions but lowers NOx and exhaust gas temperatures. The reduction of NOx in B100 was 20.41% and 16.39% when compared to water emulsion and glycerine emulsion at 10% concentration without EGR, and this reduction continued to 44.07% and 43.25% at maximum EGR % at 3000 rpm and high load respectively
