Prehistoric monument alignments on lunar standstills are currently understood for horizon range, perturbation event, crossover event, eclipse prediction, solstice full Moon and the solarisation of the dark Moon. The first five models are found to fail the criteria of archaeoastronomy field methods. The final model of lunar-solar conflation draws upon all the observed components of lunar standstills – solarised reverse phased sidereal Moons culminating in solstice dark Moons in a roughly nine-year alternating cycle between major and minor standstills. This lunar-solar conflation model is a syncretic overlay upon an antecedent Palaeolithic template for lunar scheduled rituals and amenable to transformation.

Near Field Scanning

In general, conventional methods of optical imaging are limited in spatial resolution by either the wavelength of the radiation used or by the aberrations of the optical elements. This is true whether one uses a scanning probe or a fixed beam method. The reason for the wavelength limit of resolution is due to the far field methods of producing or detecting the radiation. If one resorts to restricting our probes to the near field optical region, then the possibility exists of obtaining spatial resolutions more than an order of magnitude smaller than the optical wavelength of the radiation used. In this paper, we will describe the principles underlying such "near field" imaging and present some preliminary results from a near field scanning optical microscope (NS0M) that uses visible radiation and is capable of resolutions comparable to an SEM. The advantage of such a technique is the possibility of completely nondestructive imaging in air at spatial resolutions of about 50nm.

Аннотация. Макалада романдын мазмунунан орун алган пейзаждык сүрөттөөлөр талкууланат. Пейзаждык сүрөттөөлөр чыгарманын көркөмдүүлүгүн, эстетикалык баалуулугун арттыруу менен катар эле каармандардын образын тереңден ачып берүүдө, окуялардын өнүгүп-өсүшү жана алдыда боло турган окуялар тууралуу окурманга маалымат берүүдө кошумча каражат катары колдонулат. Жазуучу романда пейзаждык сүрөттөөлөрдү өтө кылдат колдонгону байкалат. Алсак, тоо адамдагы улуулук жана бийиктикти айгинелейт, толукшуган ай жан- дүйнөнүн бөксөрбөй толуп турушун көрсөтөт, ачык асмандын алай-дүлөй түшкөн көрүнүшкө айланышы - каармандын ички сезими, уйгу-туйгу ойлонуусу, жан дүйнөсүнүн бурганак болушун ачып көрсөтүүдө маанилүү болсо, чабалекейлердин тынымсыз учуп чабалакташы, жан алакетке түшүп чыйпылдашы – алдыда боло турган кырсыктуу окуя тууралуу кабар берсе, согуштун апааты жашыл шибердин, бак-дарактардын күлгө айланышы, чымчык-куштардын күздү күтпөй кайдадыр учуп кетип жатышы менен түшүндүрүлөт. Tүйүндүү сөздөр: пейзаж. роман, идея, легенда, эпилог, каарман, негизги окуялар. Аннотация. В статье дается пейзажное описание. Пейзажное описание используется в произведении как дополнительное средство эстетических ценностей и помогает раскрыть образы героев, и действия произведения. Писатель в романе тонко использует пейзажное описание. Например горы возвышенное и самое ценное в человеке, а полная луна – счастливое душевное состояние человека, а превращение безоблачного неба в бущующий вид – указывает, как неспокойно в душе главного героя, его беспокойные мысли, как бушует его внутренний мир, а ласточки неспокойно летающие, предвещают несчастье, птицы улетающие раньше времени, превращение зелёной травы, деревьев в пепел предвещают ужасы войны. Ключевые слова: пейзаж. роман, идея, легенда, эпилог, герой, главное событие Annotation. The article discusses the landscape description. The landscape description is used in the work as an additional tool for aesthetic values and helps to reveal the images of heroes, and in the development of the action of the work/ The writer in the novel subtly uses the landscape description. The mountains are the sublime and the most valuable in a person, and the full moon is a happy state of mind of a person, and the transformation of a cloudless sky into a raging view indicates how restless the soul of the protagonist is, his restless thoughts. How his inner world is raging, and the swallows are restlessly flying, foreshadow the misfortune, the birds flying away ahead of time, the transformation of green grass, trees in the forehead the horrors of war. This article describes the idea of the story "Do not kill" which is given instead of the epilogue in the novel "When the mountains fall" which was written by Ch.Aitmatov. It considers the role of a story that calls to live in peace and to end wars that are occurring in the world. Keywords: Landscapе, novel, idea, legend, epilogue, hero, main event.

The article presents the results of field studies in the area of the Belarusian NPP in the pre-operational period. The «background» contents of gamma-emitting radionuclides in individual components of the environment are determined. The main array of dose rate measurements in the area of the NPP construction site is in the range 0.048 ÷ 0.089 μSv/h. External radiation in the surveyed area is formed at 96% due to 40K, 226Ra and 232Th. The information obtained can be used to correctly interpret the data of future radiation monitoring during normal operation of nuclear power plants.

Trends in higher education pedagogy increasingly point to the importance of transformational experiences as the capstone of liberal arts education. Practitioners of ethnography, the quintessential transformational experience of the social sciences, are well-positioned to take the lead in designing courses and term projects that afford undergraduate students opportunities to fundamentally reshape their understanding of the social world and their own involvement within it. Furthermore, in the United States, colleges and universities have become proponents of service learning as a critical component of a holistic educational experience. In this article, we describe how service learning can be incorporated into training students in ethnographic field methods as a means to transformational learning and to give them skills they can use beyond the classroom in a longer trajectory of civic participation. We discuss strategies, opportunities, and challenges associated with incorporating service learning into courses and programs training students in ethnographic field methods and propose five key components for successful ethnographic service learning projects. We share student insights about the transformational value of their experiences as well as introduce some ethical concerns that arise in ethnographic service-learning projects.

Rising Sea Levels

The storm came on the night of 31 October. It was a full moon, and the tides were at their peak; the great rivers of eastern Bengal were flowing high and fast to the sea. In the early hours the inhabitants of the coast and islands were overtaken by an immense wave from the Bay of Bengal — a wall of water that reached a height of 40 feet in some places. The wave swept away everything in its path, drowning around 215,000 people. At least another 100,000 died in the cholera epidemic and famine that followed. It was the worst calamity of its kind in recorded history. Such events are often described as "natural disasters." This book turns that interpretation on its head, showing that the cyclone of 1876 was not simply a "natural" event, but one shaped by all-too-human patterns of exploitation and inequality — by divisions within Bengali society, and the enormous disparities of political and economic power that characterized British rule on the subcontinent. With Bangladesh facing rising sea levels and stronger, more frequent storms, there is every reason now to revisit this terrible calamity.

Abstract Molecular classification of glioblastoma has enabled a deeper understanding of the disease. The four-subtype model (including Proneural, Classical, Mesenchymal and Neural) has been replaced by a model that discards the Neural subtype, found to be associated with samples with a high content of normal tissue. These samples can be misclassified preventing biological and clinical insights into the different tumor subtypes from coming to light. In this work, we present a model that tackles both the molecular classification of samples and discrimination of those with a high content of normal cells. We performed a transcriptomic in silico analysis on glioblastoma (GBM) samples (n = 810) and tested different criteria to optimize the number of genes needed for molecular classification. We used gene expression of normal brain samples (n = 555) to design an additional gene signature to detect samples with a high normal tissue content. Microdissection samples of different structures within GBM (n = 122) have been used to validate the final model. Finally, the model was tested in a cohort of 43 patients and confirmed by histology. Based on the expression of 20 genes, our model is able to discriminate samples with a high content of normal tissue and to classify the remaining ones. We have shown that taking into consideration normal cells can prevent errors in the classification and the subsequent misinterpretation of the results. Moreover, considering only samples with a low content of normal cells, we found an association between the complexity of the samples and survival for the three molecular subtypes.
