Discovery of agriculture was no doubt the greatest development in the history of mankind. Irrigation, being one of the most crucial input in the process of agricultural development, has been sought to be developed. In India, although significant efforts have been made to develop the irrigation potential through major and minor irrigation, yet there has been rather inadequate awareness of the economics of irrigation. Particularly, very few comparable attempts have been made to examine the rational allocation of water between different regions, crops and over time. Most of the studies that have been made in this field, have examined the different sources of irrigation in isolation from one another. In the present study, it is intended to examine the different sources of irrigation in an integrated manner and thus provide a macro-prospective as a guide to formulation of rational policies for irrigation management. In the present study, it is proposed to study the allocation of water by regions and crops and also over time. An attempt will be made to draw out policy implications and make some specific recommendations.

This chapter introduces the author’s fieldwork and the focus of the book: using narrative approaches to understand and represent exile. The chapter reviews the progress narrative work has made in the discipline of psychology and how it provides a useful approach to the study of exile for reasons that are theoretical, methodological, and rhetorical. The author sketches the history of the Tibetan exile and explains how it provides a useful site to investigate the issues that are at the heart of the book, including the transmission of stories, and traumas, over time. Finally, the author introduces the informants who feature significantly in the book.

The only fragment from the Chronicle of George Synkellos in Slavic translation is found in a chronographic compilation known in five Russian witnesses of the 15th – 16th cc. A large and coherent excerpt from the Chronography of Julius Africanus that survived in about 100 fragments scattered in Latin, Greek and Eastern traditions became a basis of the compilation. Africanus’ excerpt reveals the Christian history of the world from the Creation to the Resurrection of Christ and occupies about two thirds of the whole text. It is complemented by the end of Synkellos’ Chronicle that stops with Diocletian’s reign and by the beginning of the Chronicle of his follower Theophanes the Confessor, which brings the narrative to the foundation of Constantinople. The missionary pathos of the compilation leaves no doubt and makes us think that it occurred on Byzantine soil in the first half of the 9th c. after the end of the iconoclasm. The Linguistic features of the Slavonic text prove that the translation was made in Bulgaria in the early 10th century during the reign of Simeon the Great (893–927). The paper explores the traces of the editorial work of the compilers, who were supposed to bring into line the two historical narratives that disagree in their historical and chronological concepts and refer to different sources. The problem deserves attention given the fact that in the beginning of the last century V. Istrin erroneously identified the compilation as an abridged and even draft version of the Chronicle of Synkellos.

The enduring experience of hardship, in the form of layers of various crises, can become deeply ingrained in a society, and people can come to act and react under these conditions as if they lead a normal life. This process is explored through the analytical concept of duress, which contains three elements: enduring and accumulating layers of hardship over time, the normalization of this hardship, and a form of deeply constrained agency. We argue that decisions made in duress have a significant impact on the social and political structures of society. This concept of duress is used as a lens to understand the lives of individual people and societies in Central and West Africa that have a long history of ecological, political, and social conflicts and crises.

Abstract Background: It is now recommended that all samples with raised prolactin should be examined for the presence of macroprolactin. We performed a retrospective review of our experience of macroprolactin to determine the incidence and the natural history of macroprolactin. Methods: A retrospective study of macroprolactin was made in a large clinical laboratory. Macroprolactin was measured on those samples where it is requested and where the total prolactin is >1000 mIU/L. Prolactin was measured using the Siemens Centaur and macroprolactin was measured following polyethylene glycol (PEG)-precipitation. Results: The incidence of macroprolactin in samples where the total prolactin was >1000 mIU/L was 36/670 (5.4%). During this period, 12,064 samples were received for prolactin analysis. Over the period since 2006, 22 subjects had a sample with an isolated macroprolactin measurement followed by another sample without macroprolactin after a median period of 0.46 years. Twenty-five subjects had multiple consecutive measurements of macroprolactin lasting a median period of 2.1 years. Fourteen subjects had more than six samples which had been subjected to PEG precipitation. In these subjects, the reproducibility of PEG precipitation over a median of 6 years was 1.1% CV (recovery 75% [26–110] (median [range])). Conclusions: The presence of macroprolactin can change over time and we cannot advise that once a test for macroprolactinemia has been performed that it is not necessary to repeat the investigation if a subsequent sample is hyperprolactinemic; nor can one assume that macroprolactin will not develop even if it has been excluded previously.

Two matters are considered in this paper.(i) The identification of the first version of Kaaps, the progenitor of Afrikaans. The earliestversion of Kaaps was recorded during the first period of the history of Afrikaans – theperiod prior to 1652. This period commences with the first visits to the Cape by Dutchmariners. The written records of Kaaps dating from that period are older than anyother manifestation of forms in Afrikaans. Some of these early words are currently stillin use among speakers of Kaaps, while others have been incorporated into StandardAfrikaans, or appear in dictionaries and the AWS (Afrikaanse Woordelys en Spelreëls –Wordlist and Spelling rules for Afrikaans). Some even continue to survive in the spokenAfrikaans of a number of regional dialects. Reference is also made in this chapter tohow Kaaps eventually developed and played an important role in the shaping of othervarieties of Afrikaans.(ii) The circumstances leading to the incorporation of elements of other varieties into the coredescription of Afrikaans. In describing Afrikaans, language historians usually ask whereparticular words and constructions come from. But the question how is actually ofgreater value when investigating the development of Afrikaans. Ek (I) is a word inKaaps which was, over time, absorbed into general use in Afrikaans. An analysis ofhow this process took place reveals that the ‘how’ questions are of greater importancein the history of the language than the ‘when’ and ‘where’ questions. The true story ofAfrikaans is a socio-historical one. Destigmatization, and the circumstances leading tochanging norms, are evoked by the ‘how’ questions.

Significant discoveries are made in Turkology in recent years. As a result, there is a great opportunity to explore in-depth of the history of the word. If to be exact, the most important things, the archetypes of consonant of Turkic languages (including world languages in its broad sense) are identified. Significant results are made due to the fact of clarification of original and archaic types of sounds. The importance of the restoration of archetype of consonants and vowels in retrospective direction or, on the contrary, the replacement of their synchronic variants that were formulated over time in perspective direction is the following: if etymology of any word is analyzed, it will be easier to explore its origin.

Irrigation is a major input for the development of agriculture in any country, the greatest development in the history of mankind was the discovery of agriculture and then irrigation. Irrigation has been practiced from very ancient times in our country; irrigation assumes paramount importance lest the vagaries of nature and uncertain rainfall lead to ruining of crops resulting in famine conditions. Irrigation serves a dual purpose in agriculture, it provides protection to crops against destructions and damage by failure of rainfall and irrigation helps to increase yield of crops even in normal condition. Hence irrigation is important, without irrigation agricultural production could not increase, but for that water is necessary for practice of agriculture. In India agriculture is carried out with the help of irrigation. Irrigation means supply of artificial means of water, it is one of most crucial inputs in the process of agriculture development, so significant efforts have been made the develop the irrigation potential through the projects. Some time minor irrigation projects play vital role in transforming the agriculture into productive agriculture as well as changing the overall social-economic structure of the area similarly agriculture gets stability also. Hence in this research paper an attempt has been made to how impact on population of minor irrigation project in Warud Tahsils.

Development of groundwater irrigation (GWI) has been very impressive in India, especially after the introduction of the green revolution. The area under GWI accounts for 62% of the net irrigated area today. Though GWI provides added benefits to farmers, compared to other sources of irrigation, the continuous exploitation of groundwater of late has resulted in a drastic drop in the water table, and led to salinization and quality deterioration in different parts of the country. Since groundwater contributes overwhelmingly to agricultural growth, the unrestrained exploitation of groundwater could hamper the future growth of agriculture. GWI is controlled by many factors, which are dynamic and bound to change along with the agricultural development. Therefore, one needs to understand the factors determining groundwater development in different regions over time to understand the dynamics of groundwater use. Though many studies are available on different aspects of GWI in India, not many studies have looked at the sustainable aspects of GWI, considering the major States of India together. An attempt is made in this paper to study the development as well as the factors determining GWI over time, using state-wide data to suggest appropriate interventions to sustain the use of groundwater.

Central Africa remained botanically unknown to the outside world up to the end of the eighteenth century. This paper provides a historical account of plant explorations in the Luangwa Valley. The first plant specimens were collected in 1897 and the last serious botanical explorations were made in 1993. During this period there have been 58 plant collectors in the Luangwa Valley with peak activity recorded in the 1960s. In 1989 1,348 species of vascular plants were described in the Luangwa Valley. More botanical collecting is needed with a view to finding new plant taxa, and also to provide a satisfactory basis for applied disciplines such as ecology, phytogeography, conservation and environmental impact assessment.

Medieval Scottish economic and social history has held little interest for a unionist establishment but, just when a recovery of historic independence begins to seem possible, this paper tackles a (perhaps the) key pre-1424 source. It is compared with a Rutland text, in a context of foreign history, both English and continental. The Berwickshire text is not, as was suggested in 2014, a ‘compte rendu’ but rather an ‘extent’, intended to cross-check such accounts. Read alongside the Rutland roll, it is not even a single ‘compte’ but rather a palimpsest of different sources and times: a possibility beyond earlier editorial imaginings. With content falling (largely) within the time-frame of the PoMS project (although not actually included), when the economic history of Scotland in Europe is properly explored, the sources discussed here will be key and will offer an interesting challenge to interpretation. And some surprises about their nature and date.
