to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...

the experiment was carried out in poultry experimental station belonging to nrc, cairo, egypt. a total of 120 fayoumi layers, 45 weeks old, were randomly divided into four equal groups. each group included three replicates (10 hens in each). the first group was fed the control diet containing 3.3% gram ca, whereas, the other three received diets containing 2.8, 2.6 and 2.4% gram ca, respectivel...

the study was conducted to determine the effects of turkey (meleagris gallopavo)egg weight on certain egg traits and hatching performance. a total of 178 turkey eggs comprising of three different egg weight groups below 60 g (g i), 61 to 69 g (g ii) and above 70 g (g iii) were used for this study. average egg weight (g), egg length (cm), egg breadth (cm) and egg volume (cm3) values increased wi...

this study describes the influences of variations in life history traits and developmental patterns of pelophylax ridibunda. the causes of this variation were investigated by comparing observed patterns of interpopulational differences from geographic variables. the aim of the study was to investigate whether embryos and larvae from different populations of p. ridibunda show the same pattern of...

Results We recorded 38 children that underwent 75 challenges. The median age at challenge was 15 months and 68,4% (26/38) of the children were boys. 50% (14/28) of the children had a family history of atopy. 66 % (25/38) of the children were diagnosed with atopic dermatitis at the time of reaction or/and at diagnosis. 73% (19/26) of the children with atopic dermatitis had only mild persistent s...

Giant liposomes are proposed as a potential delivery system in marine copepods, the dominant constituent of the zooplankton. Liposomes were prepared in the same size range as the food ingested by copepods (mean diameter of about 7 microm). The encapsulation of a hydrophilic and high molecular mass fluorescent compound, fluorescein isothiocyanate-dextran (FitcDx), within the liposomes provided a...

An unusually popular index reflecting the quality of egg contents and known as Haugh unit (HU) score is empirical in nature. Because that, a number studies appeared that contradict or try to improve this index. In regard, we set study pursued several goals: (i) trace rationale for developing HU give it theoretical reassessment; (ii) based on assumptions previous field, revisit refine by increas...

Leptopanchax opalescens is a critically endangered small annual fish. Reproductive traits of this species were studied to improve our understanding the strategies that facilitate occupation temporary wetlands. We compiled egg diameter and maximum total length data from 136 neotropical killifishes (Rivulidae) establish comparisons between with different life histories. tested hypothesis have sma...
