the spatial distribution of mineralization is the foremost concern in regional exploration and it could be considered as a very important tool in the investigation of mineral deposits. there are several data manipulation methods by which the data can be evaluated. fry analysis is a good method to determine the direction(s) of maximum continuity of the deposits and could be used in different typ...

this study was carried out to determine the effects of immunogen as a prebiotic on growth-related parameters and gut micro-flora in r. kutum fry. a basal diet was formulated using common feed ingredients supplemented with immunogen at 0, 1, 1.5, and 2 g kg-1 leading to four experimental diets.  fish were randomly distributed in 500 l fiberglass tanks (1×1×0.5 m). the experiment lasted for eight ...

Milkfish, Chanos chanos, is one of the major inland cultured fish species in Taiwan. Variations land resources and climate have led to application two distinct culture practices milkfish polycultures with white shrimp, Penaeus indicus. This study applies a translog cost function model analyze production scale economy input demand price elasticity four polyculture systems different periods (OWC ...

In this paper we consider a triangular inter-dependence between hyperinflation, financial repression, and the crisis in FRY 1990s. When all three vertices of triangle are present, propagates is amplified along its edges. We focus, especially, on less studied link repression FRY. Setting administrative limits interest rates under conditions hyperinflation leads to deeply negative real rates. The...

Photoaldrin, photodieldrin, and photoheptachlor are more toxic than their corresponding parent compounds (aldrin, dieldrin, and heptachlor) to freshwater invertebrates and vertebrates, and to adult houseflies. The increase in toxicity is very significant in the case of the amphipod, Gammarus (1 .5 -12 times), bluegill fry (3.6 5.7 times), mosquito larvae, Aedas (2 .3 -6 times), minnow fry (2.5 ...

There is persistent commercial interest in the use of growth modified fishes for shortening production cycles and increasing overall food production, but there is concern over the potential impact that transgenic fishes might have if ever released into nature. To explore the ecological consequences of transgenic fish, we performed two experiments in which the early growth and survival of growth...

The fertilized eggs of Japanese medaka (Oryzias latipes) were exposed to estrone (E1) at 5-5000 ng L(-1) for 15 d, and the hatched fry were exposed continuously to the same concentrations for the additional 15 d. Adverse effects on hatchability, time to hatching, and gross abnormalities occurred at 50 ng L(-1) or above. Then the fry were divided into a continual exposure group, and a water reco...

The binding, internalization and degradation of 200 pM monoiodinated human atrial natriuretic factor-(99-126) (125I-hANF) by cultured bovine aortic endothelial cells (BAECs) were studied at 37 degrees C. 125I-hANF was rapidly cleared from the extracellular medium (t1/2 approximately 10 min), whereas preincubation of the cells in the presence of 20 mM-NH4Cl or 0.2 mM-chloroquine resulted in a si...

A CONSIDERABLE amount of work has been carried out on the relationship between the small intestine and the skin in various disorders during the past decade and this article will be concerned with the small intestine rather than the whole of the alimentary tract. The exact relationship between the small intestine and skin disease has posed many problems in the past and how one organ may influenc...

The aggressive expansion of ‘unconventional natural gas development’ — more widely known as ‘fracking’ — has triggered protests across Europe. The concern is not just the direct impact on the environment but the production of fossil fuel in quantities we can no longer afford to burn, along with the side effect that the availability of cheap gas undermines the economic viability of sustainable e...
