The effect of malnutrition on the adrenal cortex has not been well studied. Earlier reports suggested that malnutrition in man produced adrenocortical hypofunction (Zubiratn and Gomez-Mont, 1953), and more recent reports suggest normal function (Lurie and Jackson, 1962) and possibly hyperfunction of the adrenal cortex in malnourished infants (Alleyne and Young, 1966). The purpose of this study ...
We present a novel method for determining sentiment intensity. The main goal is to assign a phrase a score from 0 to 1 which indicates the strength of its association with positive sentiment. The proposed model uses a rich set of features with Gaussian processes regression model that computes the final score. The system was evaluated on the data from 7th task of SemEval 2016. Our regression mod...
One of the very important issues discussed in the recent two decades is climate change. Temperature is one of the indicative factors of climate change. The present research aimed at studying temporal variation in temperature over Guwahati, Tezpur, Dibrugarh (Mohanbari) and Silchar stations, Assam, India, during the period 1981–2010. Trends in annual and seasonal temperature series were analyzed...

The purpose of this study was to investigate the association of urolithiasis with risk factors . Methods & materials : This is a cross-sectional descriptive-analytic study. The sample size was 200 patients and The data collection tool was a questionnair...
thunderstorms are climatical phenomena, which sometimes can cause irreparable damage to the ecology. in this study to identify any trends in the frequency of days with thunderstorms in iran, long-term statistics of 33 synoptic stations, from the beginning until 2005 was used. at first by applying nonparametric man-kendall and senâs estimator methods on four seasonal time series, and one annua...
Temperature, humidity and precipitation in an area, are parameters proved influential in the climate of that area, and one should recognize them so that he can determine the climate of that area. Climate changes are of primary importance in climatology, and in recent years, have been of great concern to researchers and even politicians and organizations, for they can play an important role in s...
In this study, ETo was calculated using FAO-56 Penman Monteith method. Lag-1 autocorrelation coefficient was performed to detect the presence of serially correlation in data series. Mann-Kendall (MK) or Modified Mann Kendall (MMK) and Spearman’s rho test were applied to detect the trend in annual and monthly ETo at 8 districts over 49 years (1960–2008) in the Soenath river basin, Chhattisgarh (...
Hail precipitation is characterized by enhanced spatial and temporal variability. Association Nationale d'Etude et de Lutte contre les Fléaux Atmosphériques (ANELFA) installed hailpad networks in the Atlantic and Midi-Pyrénées regions of France. Historical data of hail variables from 1990 to 2010 were used to characterize variability. A total of 443 stations with continuous records were chosen ...
