Abstract. The El Niño–Southern Oscillation (ENSO) modulates the lightning flash density (LFD) variability over India during premonsoon, monsoon and postmonsoon seasons. This study intends to shed light on impact of ENSO phases LFD Indian subcontinent using data obtained from Optical Transient Detector (OTD) Lightning Imaging Sensors (LIS) onboard Tropical Rainfall Measuring Mission (TRMM) satel...

 The Indian riverine buffaloes are more susceptible to variations in the environment. These variations affect seminal plasma proteins, which in turn affect fertility. This study was conducted to evaluate variations in the Indian Bubalus bubalis seminal plasma protein profile using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) during winter and summer seasons, and its relation wit...

Water samples from Pahang River estuary were analysed for Cu, Pb, Zn and Cd at 63 stations during the monson and non-monsoon seasons. Concentrations ranges of dissolved metals in the Chukai estuary were relatively low compared with other estuaries and are not significantly influenced by seasonal changes. Concentration of Cu in both monsoons ranged from 0.57 – 1.01 μgl-1, Pb ranged 0.88 – 1.34 μ...

BACKGROUND Vehicle exhaust is a major source of exposure to Polycyclic Aromatic Hydrocarbons (PAHs) found in the urban atmosphere. Newsagents usually work close to heavy traffic flow. The purpose of this study was to assess the breathing zone exposure of newsagents to PAHs found in the urban atmosphere of Tehran City during summer and autumn seasons and comparing the levels of exposure in both ...

We investigate the response of a climate system model to two different methods for estimating snow cover fraction. In the control case, snow cover fraction changes gradually with snow depth; in the alternative scenarios (one with prescribed vegetation and one with dynamic vegetation), snow cover fraction initially increases with snow depth almost twice as fast as the control method. In cases wh...

Quantitative microscopic structure of testis in adult Arabian rams, raised under closed grazing system in Khuzestan province of Iran, was studied in four seasons over a one year period. For this purpose, thirty adult rams were randomly selected and the live weight and scrotal circumference of rams were recorded. At the beginning of each season, among the study group, four rams were randomly sel...

Ten economically important species belonging to the Tephritidae have been recorded in Union of the Comoros (an island nation off the coast of East Africa). Little is known about the distribution of these species and how they are affected by climatic factors in the Comoros archipelago. The main objectives of this study were to characterize: (i) the population dynamics of tephritid fruit flies in...

Organic and elemental carbon (OC–EC) were measured in nearly 1000 PM2.5 samples collected from November 2011 to Maj 2014 at two sites (urban site in Bologna city and rural site at San Pietro, SP) in the Emilia Romagna region (Po Valley, Northern Italy) in eight monitoring campaigns conducted in different seasons in the framework of the Supersito project. In addition, 40 specific chemical marker...

Abstract This paper focuses on the physicochemical changes that happen in cold mix asphalts during curing, and more specifically, while after transitioning to different simulated seasons. Several tests were carried out order better grasp influence of weather (temperature humidity) curing such materials. The mechanical behaviour was assessed using oedometer tests. evolutions extracted binders, a...

The pattern of fluctuation in the population size of Bulinus globosus and Biomphalaria pfeifferi, in their infection rates with Schistosoma haematobium/S. mattheei and S. mansoni, respectively, and in the cercarial population size as monitored using hamster immersions, was elucidated in streams in the temperate highveld region of Zimbabwe over a 27-month period during 1982-1984. The results rev...
