We analyzed rainfall during the pre-monsoon season from 1979 to 2002 over the Indochina Peninsula. Our multi-year analysis confirmed that the passage of the upper trough and moisture convergence in the lower troposphere produce intermittent rainfall events during the pre-monsoon season. From this result, three questions are raised. First, what are the characteristics of the upper trough? Second...

Diatoms constitute an important component of the fouling community. Although a lot of work has dealt with the fouling diatom community structure, work on the species interactions within the community is still meagre. In this regard, a study was carried out by transferring natural diatom biofilms into controlled conditions in order to understand the roles of nutrients, initial cell inoculum and ...

The relationship between the inter-annual variability of precipitation and satellite derived Outgoing Long-wave Radiations (OLR) is studied over Pakistan during summer months for the period 1980-2007. Principal component analysis technique was applied in order to identify the major modes of oscillations present in the data series. The first four principal components explain 95% of the total var...

Natural and anthropogenic aerosols over northern India play an important role in influencing the regional radiation budget, causing climate implications to the overall hydrological cycle of South Asia. In the context of regional climate change and air quality, we discuss aerosol loading variability and trends at Kanpur AERONET station located in the central part of the Indo-Gangetic plains (IGP...

The Himalayas are a global hotspot for bird diversity with a large number of threatened species, but little is known about seasonal changes in bird communities along elevational gradients in this region. We studied the seasonality of bird diversity in six valleys of the Central Himalayas, Nepal. Using 318 plots with a 50 m radius, located from 2200 to 3800 m a.s.l., and repeated sampling during...

With the rate of fast urbanization, devasting effects air pollution are spreading across globe. Due to its connection people’s health, quality should be given more importance than other environmental measures. Air is considered a cause many human diseases. Therefore, this study intends investigate seasonal variation and “Air Quality Index (AQI)” in Chittagong city due volume, large population d...

Abstract The Kathmandu Valley in Nepal is facing a water quantity and quality crisis due to rapid urbanization haphazard wastewater planning management. Annually, groundwater extractions the exceed capture, resulting table declines. Streams are often important sources of recharge (or destination discharges from) aquifers. However, stream-aquifer interactions poorly understood. To improve this u...

AIM To determine the prevalence and diversity of Eimeria spp. in dairy cattle present in and around Guwahati, Kamrup district, Assam, India. MATERIALS AND METHODS A total of 2339 fecal samples of calves (535), heifer (641) and adult (1163) cattle were screened for 1 year present in and around Guwahati, Assam for detection of Eimeria oocysts by flotation techniques. Sporulation of the oocyst w...
