Over the past two centuries, energy needs have risen dramatically, particularly due to the transportation and industry sectors. However, the main made fuels like (fossil fuels) are polluting and their reserves are limited. Governments & research organization work together for make the use of renewable resources a priority and reduce irresponsible use of natural supplies through increased conservation. The energy crisis is a broad is biggest problem in world. Most people don't realize to their reality unless the price of fuel at the pump goes up or there are lines at the fuel station. Plastics waste fuel is sustainable and futuristic solution of fossil fuel as well as biggest problem of waste management of plastic waste can solve by this fuel. In thesis we prepare the plastic waste fuel by application of paralysis process in this process use low, medium and high grade of plastic and heated with limited amount of oxygen melt the plastic. The result of paralysis finds of liquid fuel and flammable gas. This fuel can be used as a blend in diesel with a proportion of B0D100, B10D90 B20D80, & B30D70 where B tent to blend of plastic fuel and D tend to diesel as if B0D100 means blend 0% and diesel 100%. These blend run diesel engine. The blends are in 10%, 20% & 30% plastic paralysis oil with standard diesel fuel. For experiment simultaneous optimization used a method called “Taguchi” used in the engine such as injection pressure and load condition. Taguchi Method of Optimization is a simplest method of optimizing experimental parameters in less number of trials.

Pakistan is the world's sixth most populous country, currently facing the worst energy crisis. Although rich in renewable resources, Pakistan's energy system relies mainly on fossil fuels and imported energy for its energy needs. This study aims to use an analytical hierarchy pro-cess to prioritize six renewable technologies for Pakistan, with four criteria and thirteen subcriteria. The results indicate that solar power is particularly well suited for Pakistan, as it gained 42% priority weightage in the final aggregation. Wind energy is ranked second with a priority weight of 24%, followed by hydro 13%, biomass 9%, ocean 8% and geothermal en-ergy 3%. Solar and wind energies accounted for nearly 66% of the total weightage. This result highlighted the significance of economic criteria for the selection of renewable technologies in Pakistan, with around 43% priority weightage. Environmental criteria gained 19% whereas socio-political criteria registered 14% and technical criteria 23% priority weightage. During the potential assessment of the research, it was concluded that although renewable resource development has not been allocated sufficient attention in Pakistan in the past, if the correct decisions are taken regarding the exploitation of these resources, this can remedy the country's hazardous dependence on fossil fuel and imported energy.

AbstractAccelerating innovation translation is a priority for improving healthcare and health. Although dissemination and implementation (D&I) research has made significant advances over the past decade, it has attended primarily to the implementation of long-standing, well-established practices and policies. We present a conceptual architecture for speeding translation of promising innovations as candidates for iterative testing in practice. Our framework to Design for Accelerated Translation (DART) aims to clarify whether, when, and how to act on evolving evidence to improve healthcare. We view translation of evidence to practice as a dynamic process and argue that much evidence can be acted upon even when uncertainty is moderately high, recognizing that this evidence is evolving and subject to frequent reevaluation. The DART framework proposes that additional factors – demand, risk, and cost, in addition to the evolving evidence base – should influence the pace of translation over time. Attention to these underemphasized factors may lead to more dynamic decision-making about whether or not to adopt an emerging innovation or de-implement a suboptimal intervention. Finally, the DART framework outlines key actions that will speed movement from evidence to practice, including forming meaningful stakeholder partnerships, designing innovations for D&I, and engaging in a learning health system.

Preventing the development of an ethnic Kurdish cultural and political movement has been a priority of the Turkish state since the Kurdish-led Shaykh Said Rebellion of 1925.' Nevertheless, beginning around 1959 this effort was steadily if slowly undermined, and events of the past ten years suggest that it has indeed failed. Not only have Kurdish activists gained some measure of international recognition for themselves and for the concept of Kurdish ethnic rights,2 but promoting the notion of specifically Kurdish cultural rights has almost become a standard litany for a wide array of Turkish civic and state actors, from Islamist political parties to business organizations, human-rights groups, prime ministers, and mainstream newspaper columnists. Although the separatist Kurdistan Workers Party (PKK) and its insurgency against Turkey have claimed a great deal of academic and popular attention, it is these diffuse but public re-considerations of minority rights taking place within legitimate Turkish institutions have contributed the most to the sense that past policies of coping with the “Kurdish reality” are ultimately unsustainable, and that it may be difficult, if not impossible, to return to the climate of earlier years, when discussions of ethnic difference were suppressed, limited to the private realm, or confined to the fringes of radical politics.

Let α be an admissible ordinal. In this paper we study the structure of the upper semilattice of α-recursively enumerable degrees. Various results about the structure which are of fundamental importance had been obtained during the past two years (Sacks-Simpson [7], Lerman [4], Shore [9]). In particular, the method of finite priority argument of Friedberg and Muchnik was successfully generalized in [7] to an α-finite priority argument to give a solution of Post's problem for all admissible ordinals. We refer the reader to [7] for background material, and we also follow closely the notations used there.Whereas [7] and [4] study priority arguments in which the number of injuries inflicted on a proper initial segment of requirements can be effectively bounded (Lemma 2.3 of [7]), we tackle here priority arguments in which no such bounds exist. To this end, we focus our attention on the fine structure of Lα, much in the fashion of Jensen [2], and show that we can still use a priority argument on an indexing set of requirements just short enough to give us the necessary bounds we seek.

Seventy years have elapsed since the Nutrition Society was founded and John Boyd Orr became its first Chairman. Over the intervening period, nutrition research has embraced and responded to a wide variety of challenges as the requirements of research have evolved and changed. This paper reflects on some of the major challenges that have influenced nutrition research over the past 70 years and considers where nutrition stands today along with the challenges for the future. In the past, these challenges have included food security and improvements in animal nutrition to enhance production through problems of overnutrition, such as CVD and obesity, as well as the recognition of the importance of early-life nutrition. The challenges for the future include how to translate the increasingly comprehensive and complex understanding of the relationship between nutrition and health, being gained as a result of the genomic revolution, into simple and accessible policy advice. It also includes how we learn more about the ways in which diet can help in the prevention of obesity as well as the ways in which we prevent the rise in complex diseases in emerging nations as they undergo nutritional transition. From this, it is clear that nutrition research has moved a long way from its initial focus on nutritional deficiencies to a subject, which is at the heart of public health consideration. This evolution of nutrition research means that today diet and health are high on the political agenda and that nutrition remains a priority area for research. It has been 70 years since 1941 when the Nutrition Society was established, under its first Chairman, John Boyd Orr. At that time there were many who believed that nutrition research had reached its peak and there was little left to discover. This view stemmed from the fact that most vitamins and minerals had been discovered and that the syndromes associated with nutritional deficiencies in these were largely known. Despite this gloomy prognosis, the intervening 70 years have witnessed a remarkable evolution in nutrition research, which has underpinned key Government policies, ranging from food security right through to public health. This review considers some major developments that have helped to shape nutrition research over the past 70 years and in so doing have changed its frontiers.

The continuous indentation test, which applies an indentation load to a material and records the indentation depth, yields indentation tensile properties whose accuracy can vary depending on such experimental parameters as number of unloadings, unloading ratio, maximum depth ratio and indenter radius. The Taguchi method was used to quantify their effects and to determine their optimum values. Using signal-to-noise ratio calculated from the error in the indentation tensile properties, the criterions and the optimum values for the experimental parameters were presented. The indentation tensile properties evaluated with the optimum parameters were in better agreement with the tensile properties.

Some previous research results have shown that EGR (exhaust gas recirculation) rate, pilot fuel quantity, and main injection timing closely associated with engine emissions and fuel consumption. In order to understand the combined effect of EGR rate, pilot fuel quantity, and main injection timing on theNOx(oxides of nitrogen), soot, and ISFC (indicated specific fuel consumption), in this study, CFD (computational fluid dynamics) simulation together with the Taguchi method and the ANOVA (analysis of variance) technique was applied as an effective research tool. At first, simulation model on combustion and emissions of a light duty diesel engine at original baseline condition was developed and the model was validated by test. At last, a confirmation experiment with the best combination of factors and levels was implemented. The study results indicated that EGR is the most influencing factor onNOx. In case of soot emission and ISFC, the greatest influence parameter is main injection timing. For all objectives, pilot fuel quantity is an insignificant factor. Furthermore, the engine with optimized combination reduces by at least 70% forNOx, 20% in soot formation, and 1% for ISFC, in contrast to original baseline engine.
