AbstractThe rapid increase in urban lighting, with the resultant increase in sky glow due to this lighting, has already severely affected both professional and amateur astronomy. It is not possible to observe as faint as was possible in the past from sites anywhere near large cities. Even those sites near smaller cities are compromised.There are other adverse effects of outdoor lighting. One in particular affects amateur astronomers (more than professionals, in fact). That is light trespass from a (usually) nearby source shining directly into the amateur’s observatory. It ruins dark adaption and can even affect photographic or photoelectric observations.Astronomers are pushing for communities and individuals to apply “solutions”, which can help greatly. These are: use the correct amount of light for the lighting task, not overkill; use controls on the lighting, such as shielding and correct placement (direct the light downward), and time controls; use low pressure sodium light sources whenever possible (especially in the vicinity of professional observing sites).Without the widespread application of such solutions, amateurs, professionals, and even the general public will likely lose forever their superb view of the universe, as seen from a prime dark sky site. These solutions also maximize the quality of any lighting installation, often at lower cost than bad lighting.

With the advancement of the quality of life and the resultant increase in the frequency of life-threatening diseases, food is being viewed as a source of nutritional and functional benefits. Mushrooms have served as nutritious food from time immemorial along with useful medicinal properties. The genus Ramaria, coral fungi, is a potential group of culinarily acclaimed mushrooms with worldwide distribution. During the past two decades, studies on several species of the genus revealed high medicinal potency. In this review, we particularly aim to update this group's present status with respect to its importance as food and medicine, which will offer a new perception to researchers for its progress from dietary food to functional food.

<p>The nature is real teacher for a person who wish to develop their intelligence. Intelli­gence is a natural quality of live. The universe intelligence are hidden everywhere, and if we have eyes to see, we can see it everywhere. We can learn from animals on how they sleep, they live and their interaction each others. Most people in every traditional culture learn based on their beliefs rather than their reason (Suryadarma, 2012). There are many different ways to look the uniqueness of biodiversity and the interrelationship between humans and their social and biophysical surroundings. <br />People in the past; i.e. hunting and gathering communities were heavily depended on their immediate natural resources to meet most of their basic needs. Therefore, they closely interacted with their environment and thereby, gained a sound knowledge and understand­ing the uniqueness of each species and its underlying ecological processes. Many events in daily life is interesting, in the sense that many phenomena and objects can be directly ob­served. The richness of biological pehenomena in the ecosystems can be directly observed. Some phenomena had recorded as a proverbs, analogy and song. <br />Balinese use the uniqueness of biodiversity resources and ecological phenomena in their daily life to find analogy, proverb and song to reflect their life. Yesudian (1989) declared; that man is the culminating point of the creation but in the man alone are animal, human and divine qualities alive and active together. Which aspects of our nature are to manifest? To manifest the humanity is the purpose of our earthly life (Suryadarma, 2010). This is the rea­son why the Balinese use proverbs, analogy, and song as part of learning process. Learning is processes of our escalation where it processes e.g. it can be analogized with the process of transformation on butterfly life cycle <br />Tsunami is a large ocean waves that washes everything in the shallow water of a shore­line where globalization can be analogized with tsunami process in which the world increas­ingly their activities. Globalization is the fact where the people have been two ways in look­ing at it impact on their life activities. It is the reason why each person use different ways looking of proverbs, analogy in our cultural activities. How develop its in deferent level and different site into better science for better life? How to explore and develop it as sources of biodiversity documentation information because these activities will be developed the fra­grance of ecological wisdom and enter in every one heart.</p>

I must begin with the words of the clergyman: ‘My short sermon for today is divided into three parts. One: God. Two: Man. Three: The Universe.’ It will be impossible to do justice to the subject in hand in the short span of one lecture. This is not only because of the vast range of time and space involved in any consideration of the parting of the ways between eastern and western Christianity in the late antique period. To embark on such a theme involves holding up for scrutiny the very nature of ecclesiastical history. For what we have to deal with is not merely what happened in the relations between east and west, but why what happened happened as it did. Once the ecclesiastical historian asks why, he will find himself sooner or later forced to grapple with the whole quality of men’s lives in the past—that is, with how they lived the full twenty-four hours of the day, not only in their books, but in their churches, not only in their churches, but in the most intimate and most monotonous rhythms of their life.

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

The article describes the results of comprehensive study aiming at increase of quality of LED luminaires and definition of the nature of changes in their correlated colour temperature (CCT) in the course of operation. Dependences of CCT of LED luminaires with remote and close location of phosphor for 10 thousand hours of operation in different electric modes were obtained; the results of comparison between the initial and final radiation spectra of the luminaires are presented; using mathematical statistics methods, variation of luminaire CCT over the service period claimed by the manufacturer is forecast; the least favourable electric operation modes with the highest CCT variation observed are defined. The obtained results have confirmed availability of the problem of variation of CCT of LED luminaires during their operation. Possible way of its resolution is application of more qualitative and therefore expensive LEDs with close proximity of phosphor or LEDs with remote phosphor. The article may be interesting both for manufacturers and consumers of LED light sources and lighting devices using them.

Heart failure (HF) affects more than 5 million people and has an increasing incidence and cost burden. Patients note symptoms of dyspnea and fatigue that result in a decreased quality of life, which has not drastically improved over the past decades despite advances in therapies. The assessment of exercise capacity can provide information regarding patient diagnosis and prognosis, while doubling as a potential future therapy. clinically, there is acceptance that exercise is safe in hf and can have a positive impact on morbidity and quality of life, although evidence for improvement in mortality is still lacking. specific prescriptions for exercise training have not been developed because many variables and confounding factors have prevented research trials from demonstrating an ideal regimen. Physicians are becoming more aware of the indices and goals for hf patients in exercise testing and therapy to provide comprehensive cardiac care. it is further postulated that a combination of exercise training and pharmacologic therapy may eventually provide the most benefits to those suffering from hf.

Neurosurgery is among the newest of surgical disciplines, appearing in its modern incarnation at the dawn of twentieth century with the work of Harvey Cushing and contemporaries. Neurosurgical ethics involves challenges of manipulating anatomical locus of human identity and concerns of surgeons and patients who find themselves bound together in that venture.In recent years, neurosurgery ethics has taken on greater relevance as changes in society and technology have brought novel questions into sharp focus. Change of expanded armamentarium of techniques for interfacing with the human brain and spine— demand that we use philosophical reasoning to assess merits of technical innovations.Bioethics can be defined as systematic study of moral challenges in medicine, including moral vision, decisions, conduct, and policies related to medicine. Every surgeon should still take the Hippocratic Oath seriously and consider it a basic guide to follow good medical ethics in medical practice. It is simple and embodies three of the four modern bioethics principles – Respecting autonomy, beneficence, nonmaleficence, and justice.Spinal cord injury (SCI) is a devastating condition often affecting young and healthy individuals around the world. Currently, scientists are pressured on many fronts to develop an all-encompassing “cure” for paralysis. While scientific understanding of central nervous system (CNS) regeneration has advanced greatly in the past years, there are still many unknowns with regard to inducing successful regeneration. A more realistic approach is required if we are interested in improving the quality of life of a large proportion of the paralyzed population in a more expedient time frame.

This article aims to explain maqâṣid al-Qur’ân according to M. Quraish Shihab and its application in interpreting verses related to the use of social media. The problem that will be answered in this article covers two main issues, namely how the perspective of maqâṣid al-Qur’ân according to M. Quraish Shihab and how it is applied in interpreting the verses of the use of social media. The method used is the thematic method, namely discussing verses based on themes. Fr om this study the authors concluded that according to M. Quraish Shihab there are six elements of a large group of universal goals of the al-Qur’ân, namely strengthening the faith, humans as caliphs, unifying books, law enforcement, callers to the ummah of wasathan, and mastering world civilization. The quality of information lies in the strength of the monotheistic dimension which is the highest peak of the Qur’anic maqâṣid. M. Quraish Shihab offers six diction which can be done by recipients of information in interacting on social media. Thus, it aims to usher in the knowledge and understanding of what is conveyed in carrying out human mission as caliph, enlightenment through oral and written, law enforcement, unifying mankind and the universe to the ummah of wasathan, and mastery of world civilization

The aim of the work is to conduct a systematic analysis of the available research results on the possibility of using menopausal hormone therapy (MHT) in patients who successfully completed the treatment of endometrial cancer (EC). Materials and methods. The review includes data from foreign articles published in PubMed and Medline, and domestic works published on elibrary.ru over the past 40 years. Results. The results obtained allow us to consider MHT as an independent method of medical rehabilitation for women who have undergone EC. A clear patient profile should be established, allowing the use of this method, with strict adherence to health monitoring. Conclusion Patients who have successfully completed the treatment of EC require the creation of special rehabilitation conditions in the interests of maintaining health and quality of life and should be under the close attention of the doctor. Argumented approaches to the appointment of MHT in such patients will avoid complications associated with estrogen deficiency after surgery, radiation with or without systemic (cytostatic) treatment methods.

The article analyzes the main indicators of the evolution of the domestic economy and its industrial complex in the past year (in January — November 2019). It Identifies trends in this evolution, including negative trends that determine the preservation of reproductive threats in 2020: sluggishness, instability and low quality of economic growth. The main reasons for the fact that the objective resource capabilities of the macro level were clearly not used enough to effectively solve the urgent problems of technological modernization of the economy and increase people’s welfare are established. The main reason is the poor quality of public administration, including imperfect strategic planning and industrial policy; there is still no modern national innovation system in the country. Accordingly, recommendations for improving the quality of state regulation in its specified components are justified. The recommended measures, according to the author, will help the economy to move to a trajectory of rapid, sustainable and high-quality growth.
