Qai’lullah or napping is a phenomenon that is widely practiced in the world. Islam advocates mid-day napping as it is primarily practiced by the Prophet Muhammad (pbuh). Scientists and scholars also acknowledge the benefits beyond this practice after various research and studies done. Hence, this article emphasizes topic of sleep in Islamic insight, their stages of sleeps according to Quran and the practiced of Qai’lullah or mid-day napping. The high-energy blue light exposure from the natural source, Sun and also digital screens reported reduce visual contrast and affect the sharpness and clarity by creating glares lead to mental and physical fatigue. Thus, a short nap in the mid-afternoon helps to boost memory, lift our mood, and improve job performance. The effect associated with qai’lullah are also being reviewed including improved the neurocognitive performance, alertness, recover the loss night sleep and enhanced the quality and increased memory consolidation in people.

Harmful Effects

Background: There is growing concern that the increased use of personal digital devices, which emit a high proportion of their light in the blue wavelengths, may have harmful effects on the retina. Extensive historical as well as current research demonstrates that exposure to high energy visible light (blue light) can damage the retina under certain circumstances. There are, however, no studies that directly address whether blue light at the intensities emitted by digital devices can potentially cause such harm. The present review aimed to examine whether blue light exposure from computers, tablets, and cell phones can, when used habitually over a prolonged period of time, be harmful to the retinal. Methods: A search of the literature on blue light-induced retinal damage was performed using a number of scientific search engines, including BioOne Complete™, Google Scholar™, Paperity™, PubMed™, and ScienceOpen™. Studies most significant for addressing the question of possible harmful effects of blue light emitted by personal digital devices were selected from this search and reviewed. Results: The data from the selected studies were summarized and their limitations in addressing the question of whether the blue light from personal digital devices is capable of producing retinal damage were addressed. Based on these limitations, a practical experimental protocol for collecting the additional data needed was proposed. Data from pilot experiments are presented that indicate the practicality of this approach. Conclusions: The currently available data on the effects of blue light on the retina are not sufficient to refute the hypothesis that the use of personal digital devices could, over a lifetime, produce retinal damage. Additional studies, such as those proposed in this article, are needed to resolve this issue.

Night Shift Work

The purpose of this article is to provide background information and the current understanding of a less familiar cause of female breast cancer; exposure to ultraviolet light at night. Breast cancer is a common disease that causes significant morbidity and mortality in women. There are several risk factors for breast cancer, most of which are genetic and environmental in nature. An often-overlooked risk factor is exposure to blue light during night shift work, which decreases melatonin production. One of the many cancer-preventing properties of melatonin is to limit estrogen production. Increased lifetime exposure to estrogen is a well-known cause of breast cancer. Awareness of nighttime blue light exposure as a breast cancer risk factor by women doing night shift work and those exposed to nighttime light via smartphones and laptops, is essential information to know so that protective measures can be taken.

The metaphor that fundamental physics is concerned to say what the natural world is like at the deepest level may be cashed out in terms of entities, properties, or laws. The role of quantum field theories in the Standard Model of high-energy physics suggests that fundamental entities, properties, and laws are to be sought in these theories. But the contextual ontology proposed in Chapter 12 would support no unified compositional structure for the world; a quantum state assignment specifies no physical property distribution sufficient even to determine all physical facts; and quantum theory posits no fundamental laws of time evolution, whether deterministic or stochastic. Quantum theory has made a revolutionary contribution to fundamental physics because its principles have permitted tremendous unification of science through the successful application of models constructed in conformity to them: but these models do not say what the world is like at the deepest level.

ABSTRACTCerium fluoride offers a reasonable compromise between parameters like the density, the light yield, the scintillation characteristics (particularly the decay time) and the radiation hardness, and is considered today as the best candidate for large electromagnetic calorimeters in future High Energy Physics experiments. Details on the performances of large crystals produced by different manufacturers all over the world and measured by the Crystal Clear collaboration will be shown and the usefulness of a good collaboration between the industry and the users will be highlighted by some examples on the light yield and radiation hardness improvement.

Big-eyed bugs Geocoris spp. (Lygaeidae, Hemiptera) are small insects that is found in many parts of the world. They are beneficial because they eat a multitude of insect pests in agriculture. Big-eyed bugs Geocoris spp. are insects that receive research attention in Florida and elsewhere because of the benefits that this species give to plants (Mead, 2001). Big-eyed bugs reproduce many generations in a year on weeds, perennial crops, bushes. In spring the female big-eyed bugs start laying eggs on the bud, the leaves of the host plant. Understanding the biology and the role of predator Geocoris spp. in ecosystem will provide an alternative method in sustainable agriculture development. In this short review, we discuss some convenient diets for the application of mass rearing Geocoris spp.

Contemporary urban development has changed the traditional cities all over the world. In our region, the typical Balkan cities of oriental origin, structure and outlook were almost totally transformed in the second half of the 20th century. Modern movement brought new models of urban organization, different communication concepts and a variety of concepts of modern buildings. Among others, the idea of complex urbarchitectonic structures in urban tissue spread under specific influences and models. After a short review of modern urban development and the idea of complex urban structures, this paper explores urban transformation of less researched cities such as Pristina and Novi Pazar. The focus is on the phenomenon of complex urbarchitectonic structures built in related cities in a short period from 1969-1989. Four complex urbarchitectonic structures will be presented: Kicma and complex in JNA Street in Pristina and Lucne buildings and Jezero buildings in Novi Pazar.
