the experiment was conducted to evaluate the prevalence of lernaea cyprinacea and its effects on growth, hematology and skin histopathology of catla catla in four experimental earthen ponds (p1, p2, p3 and p4) for 90 days. the growth performance, prevalence of lernaea cyprinacea and ulceration was recorded on a fortnightly basis. the highest final body weight was observed in p4 (413.7 g) follow...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
in this study, the effect of garlic extract on the growth performances ( body weight increase (bwi), specific growth rate (sgr), condition factor (cf), final length (fl) and weight (fw)), feed indices (feed conversion rate (fcr), protein efficiency ratio (per), protein production ratio (ppr)) and body composition (protein, fat, moisture and ash) of mugil cephalus larvae were studied in four tre...
in chapter one we will describe definitions and preliminary results to provide the global context of our own results to be presented in detail in the subsequent chapters in chapter two we consider degree-one maps of the circle and we study their rotation set. our main result in this chapter says that if the map is topologically mixing then its rotation interval is nontrivial (that is, not reduc...
this study was carried out to investigate the effects of salinity levels (0, 2, 4, 7 and 10 ppt) on growth indices, blood biochemical parameters, and body composition in rutilus frisii kutum fingerlings (initial weight 1.330.02 g) during 60 days. results indicated that the highest rates of daily growth, specific growth and weight gain per fish were obtained at the levels of 4 and 2 ppt (p0.05)...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
introduction: low birth weight (lbw, birth weight<2500g) is a significant health problem in children all around the world. there is a direct relationship between low birth weight and infant mortality rate. one of the most important measures to prevent childhood morbidity is growth monitoring. the present study was planned to compare the growth rate of lbw neonates with those weighing 2500g and ...
crop yield estimation is one of the most important parameters for information and resources management in precision agriculture. this information is employed for optimizing the field inputs for successive cultivations. in the present study, the feasibility of sugar beet yield estimation by means of machine vision was studied. for the field experiments stripped images were taken during the growt...
