the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
Residual hydrogen (H2) gas in the analysis chamber of an atom probe instrument limits the ability to measure H concentration in metals and alloys. Measuring H concentration would permit quantification of important physical phenomena, such as hydrogen embrittlement, corrosion, hydrogen trapping, and grain boundary segregation. Increased insight into the behavior of residual H2 gas on the specime...
a significant portion of manganese (mn) chemical fertilizers applied to calcareous soils is not absorbed by the first crop and may, therefore, affect the growth as well as chemical composition of the subsequent crops, this being called the residual effect of mn, soil tests may be employed to predict such effects. the present experiment was conducted to study the residual effects of manganese su...
Application of sewage sludge on the farmland as a source of crop nutrient had recently received considerable attention. Some management practices may be required to control the accumulation of toxic elements including Pb, Ni and Cd. Sequential extraction gives useful information on plant bioavailability of the elements. The objective of this study was to investigate the cumulative and residual ...

Paraffinic phase change materials (PCM) were microencapsulated by in situ polymerization of melamine-formaldehyde prepolymers. Partly methylated trimethylolmelamine was used as an aminoaldehyde prepolymer for the microcapsule wall, a styrene-maleic acid anhydride copolymer as an emulsifier and modifying agent, and ammonia as a scavenger for reducing residual formaldehyde. For the determination ...
At the end of the final spin cycle of the laundry process, the residual moisture content (RMC) of fabric is directly related to the dynamic surface tension of the residual water in the fabric. The LaPlace equation for capillary rise predicts that the capillary rise of solutions in a capillary is proportional to the surface tension at the air-liquid interface. If fabric can be considered to be a...
in this study, the effectiveness of kiwi shell was investigated to reduce the mobility of lead and cadmium in clay soil in different intervals. for this purpose a clay soil sample was contaminated with lead and cadmium in distinct dishes with 10 and 600 ppm concentrations respectively and mixed with 5% kiwi shell. samples were placed in incubator, and then sampling of soil in incubator was perf...
An investigation of the effect of change of total CO(2) concentration from 7 to 43 mM at pH 7.35 in the medium perfusing isolated rat lungs on [U-(14)C]glucose incorporation into lung phospholipids has been carried out. The incorporation of [U-(14)C]glucose into phosphatidylcholine and phosphatidylglycerol of the surfactant fraction and of the remaining lung tissue (residual fraction) was obser...
