Археологическая летопись левобережных городов Сырдарьи: Суткент и Аркук
Authors: Талеев Докей Абдикеримович 
Published: April 2022

Важнейшее место в исторической науке принадлежит изучению вопросов взаимоотношения кочевых и оседлых народов, выявлению связей, существовавших между городом и степью. Города, расположенные на среднем течении Сырдарьи – на стыке Дешт-и-кыпчакских степей и оседло-земледельческих районов, имели большое значение в жизни кочевников. Сопоставляя письменные источники и данные археологических исследований можно заключить, что многие города казахской земли имеют 2000-летнюю и даже более древнюю историю. Раскопки, проведенные на развалинах крупных городов (Отрар, Сауран, Шымкент, Тараз), расположенных на юге Казахстана показывают, что они формировались в течение 2000 и более лет. На территории нашей страны еще есть немало древних городов, история которых еще не определена. К таким относятся города которые существовали и на левом берегу среднего течения реки Сырдарья. Данная статья посвящена анализу письменных источников и археологических данных о городах Суткент и Аркук, датируемых I в. н.э. Археологические исследования, проведенные на левом берегу Сырдарьи, показали, что эти два города за свою историю трижды меняли свое расположение, которые чередуются в хронологическом порядке. Эти развалины находятся на близком друг от друга расстоянии.

Published: April 2022

BACKGROUND: Coronary artery bypass graft (CABG) surgery is the standard of care for the management of patients with three-vessel and left main coronary artery disease (CAD) with viable myocardium. Positive inotropic agents are the treatment of choice in patients with LV dysfunction post CABG. Levosimendan is an inotropic drug that has three major mechanisms of action: positive inotropy, vasodilation, and cardiac cytoprotection. Levosimendan is a calcium sensitizer, it improves myocardial contractility by sensitising troponin C to calcium without increasing myocardial oxygen consumption and without impairing relaxation and diastolic function. AIM: The aim of this study was to determine the effect of levosimendan compared to the conventional inotropic agents on the outcomes of patients with LV dysfunction undergoing CABG. METHODS: It is a prospective observational study that patients were divided into 2 groups of 50 patients each. Group A received intravenous levosimendan (at a dose of 0.2μg per kilogram of body weight per minute for 1 hour, followed by a dose of 0.1μg per kilogram per minute for 23 hours), with the infusion started at the induction of anesthesia while Group B which included patients who received conventional drugs. Clinical examination, Hemodynamic data and Laboratory investigations pre-operative and post-operative were collected.

Effect of High Level Divergence on the Rainfall Distribution over northwest India associated with a southwest monsoon depression
Authors: VENKATARAMAN K. S. , RAO N. S. BHASKARA 
Published: April 2022

In association with a monsoon depression which recurved over east Rajasthan and moved northwards into Jammu Province, torrential rains occurred in the north Punjab and northwest Uttar Pradesh on 20 and 21 September 1962. This rainfall could not be explained in terms of the low level circulation of the depression alone, which was still far away, and was found to be associated with marked high level divergence in a deep layer extending from 500 to 200.mb levels. An examination of the peculiar features of the rainfall in different areas and the associated synoptic features has shown the relative importance of the three factors, low level convergence, moisture feed and high level divergence on the rainfall distribution.

Kohler's technique for deriving pan evaporation using solar radiation, total wind run, average air temperature and vapour pressure data has been found to yield good results under Indian conditions- Monthly normal evaporation maps using Kohler's technique have been prepared and discussed.
Certain aspects on the realization of primitive equations Forecasting model in the low latitudes
Authors: MOHANTY UC , MADAN FLTLTSC 
Published: April 2022

A number of numerical experiments are carried out with a barotropic primitive equations (PE) model for forecasting the tropical systems. A systematic approach has been made to solve some of the important problems arising in the process of integrating such a simple PE model in the low latitudes. Emphasis has been given to the initial data problem in the tropics. In order to study the influence of dynamical initialization and filtering techniques on the forecasting model and to study their smoothing characteristics, the spectral decomposition of kinetic energy of initial, initialized, forecast and actual wind fields, is carried out. Further, the improvement in the efficiency of the model by incorporating these techniques is demonstrated. Finally, this model is applied to forecast the movement of tropical cyclones and a monsoon depression in the Bay of Bengal and inspite of the constraints of the model, the results are quite encouraging.

Published: April 2022

In the present study an attempt has been made to compute vertical velocities by a 10-level balanced model in the case of a ,monsoon depression. Maximum vertical motion of the order of lO-3mb/sec is obtained. A characteristic feature of the rainfall distribution in a monsoon depression is the occurrence of fairly widespread rainfall in the SW sector, This model depicts a maximum upward motion in the same sector.
The results have been compared with the computations made by quasi-geostrophic model as well as kinematic method. The suitability of the balance model in the tropics, has been discussed.

Published: April 2022

A conversão de Cerrado natural em áreas de exploração agrícola tem modificado as propriedades físicas e alterado o conteúdo de carbono nos solos, principalmente quando o uso e manejo não contribuem para manutenção desses atributos. Esse trabalho teve por objetivo avaliar a influência do uso e manejo do solo nas propriedades físicas e carbono orgânico total em solos, em quatro profundidades nos Cerrados do oeste da Bahia. O estudo foi realizado nos municipios de Barreiras e Luis Eduardo Magalhães no Estado da Bahia. Foram escolhidos 9 pontos de coleta, em Cerrado natural, plantio direto, plantio convencional (soja e Algodão), pastagem (com 2 e 5 anos) e pastagem degradada, café com 3 e 20 anos. As coletas foram realizadas nas profundidades de 0,00-0,10; 0,10-0,20; 0,20-0,30 e 0,30-0,40 m. O sistema com plantio direto(SPD), algodão com plantio convencional (AC), pastagem com cinco anos (P5) e pastagem degradada (PD) apresentaram densidade maiores (P<0,05) que a área de referência (cerrado natural (CN)) na camada superficial (0,00-0,10 m). Os índices de agregação (DMP e DMG) mostraram-se menores que os da área de Cerado nos sistemas com plantio direto, plantio convencional ( soja e algodão) e em pastagem degradada. Quanto ao índice de estoque de carbono, para o perfil de 0,00 a 0,40 m, apenas a pastagem com 2 anos de cultivo e o café com 3 anos de idade foram superiores ao Cerrado Nativo. De modo geral, as propriedades físicas e o carbono orgânico foram alterados pelo uso e manejo do solo, tanto de forma positiva como negativa.
