a total of 12 species of marine gastropods, among which two taxa are new, is reported for the first time from the miocene deposits of khavich section, south of sirjan, kerman. gastropods assemblage in khavich area indicates deposition in shallow, warm ramp-type carbonate platform. the miocene and even oligocene gastropod assemblages, relatively similar to khavich section, reported from the othe...

The interannual variation of the Bowen ratio, through its effect on the warming extent of available energy to the ecosystem land surface air, heavily influences the ecosystem microclimate and affects the hydrological cycle at both regional and global scales. Although the precipitation amount in southeast China is not expected to change greatly as a result of climate change, the precipitation fr...

Mathematical model to predict the transport of klebsiella pneumonae has been developed the transport of the type microbial species where found to be a serious threat to the settlers in the study location; the microbes are influenced by the soil structural deposition, including the activities of man, the condition has resulted a lots of death trap to in many ways, the influence from porosity and...

The recent shift from transplanted to wet seeded rice (Oryza sativa L.) in South East Asia has resulted in major weed problems which require more labour and energy for their control. Field experiments were conducted during 1994±1996 on a Chromic Vertisol in central Luzon, the Philippines, to study the effect of water, tillage and herbicide levels on total water use, weed growth and yield of wet...

We examined soil water use patterns of four model plant associations established in the North Caribbean lowlands of Costa Rica by comparing the stable hydrogen isotope composition, deltaD, in xylem sap and in soil water at different depths, under rainy and dry conditions. Four 5-year-old model plant associations composed of 2 tree species (Hyeronima alchorneoides and Cedrela odorata) having dif...

an appropriate method to determine the hydraulic conductivity above water table is guelph permeameter. using this method, experiments can be carried out by one person in a short period. several investigators have commented on the systematic difference between the hydraulic conductivity obtained by guelph permeameter and shallow well pumping test (swpt) methods. therefore, the purpose of this re...

In order to estimate the fallout amounts of transuranium elements, monthly deposits have been collected at Tokai, Ibaraki Prefecture, during the period from October 1978 to March 1980, and were analyzed both on 241Am and 239+24opu also on major surface soil components, Si02 and A1203. Major soil matrices contents in the deposits suggested that 5.1 % of the observed 239+24°Pu deposition was cont...

Nonglacial deposits Artificial fill (Holocene)—Mud, sand, and gravel of varying proportions, possibly including foreign debris such as concrete, logs, timbers, or brick. Used for highway roadbeds and other construction. Thickness generally greater than 2 m. Mapped where fill substantially obscures or has altered original geologic deposit. Beach deposits (Holocene)—Soft sand, silt, and mud depos...
