Nanocrystalline apatites are major constituents of hard tissues, and attempts are made worldwide to prepare synthetic analogs. However the impact of synthesis/postsynthesis parameters is often disregarded. Based on an updated knowledge on such compounds, we inspected the effects of synthesis parameters (maturation time, temperature, pH, nature of counter-ions) and post-treatments (re-immersion ...

the geothermal phenomena in the area nearby the euganean hills (near padua, in italy) areknown and exploited for therapeutic purposes since ancient times, and recently also for aesthetic purposes.this paper presents the first characterization of the radionuclides content in the euganean thermal waters and mud, extended to a great number of spas. in particular the radionuclides content of both t...

This study aimed to assess the effect of rootstocks (IAC 572 and IAC 766) potassium fertilization at different concentrations (0, 75, 150 300 kg·ha-1 K2O) on phenology thermal demand Niagara Rosada grapevine, evaluate development chemical traits during maturation stage. The length main phenological stages was recorded within two production seasons. Total calculated using degree-day concept. ber...

Crude oil samples recovered from three oilfields distributed within the central Niger Delta were used to investigate biological marker fingerprints, sources of organic matter, conditions deposition, and thermal maturation. This was achieved by application gas chromatography-mass spectrometric (GC-MS) analyses on saturated components crude oils. The ratios show low sterane/hopane (steranes/hopan...

Thermoregulation in humans can be divided into three broad mechanisms of control, namely: shivering, sweating and vasomotor activity. Previous investigations suggested the presence of an autonomic rhythm, originating in the central nervous system, possibly related to thermal vasomotor control and directly affecting heart rate by reflex changes in cardiac sympathetic and parasympathetic activity...

This study was designed to investigate the effect of addition several concentrations royal jelly media used in vitro maturation process Iraqi sheep. The ovary brought from Al-Shulla slaughterhouse and transferred obstetric laboratory at College Veterinary Medicine University Baghdad by a thermal insulating box containing physiological solution with antibiotic penicillin temperature 30-38°C. In ...

the aim of the study was to compare the parthenogenetic activation and in vitro fertilization (ivf) of in vitro matured caprine oocytes. a total of 881 cumulus-oocyte complexes (coc’s) were collected from 243 ovaries. oocytes were matured in tcm-199 medium containing ecg (20 iu/ml), hcg (20 iuμg/ml), oestradiol-17β (1 μg/ml), bsa embryo tested (3 mg/ml) supplemented with 10% fetal bovine serum ...

the present article is aimed at study on agroclimatic conditions of cultivation of sunflower throughout selected substations at kurdistan  province by means of gis system. in this investigation, meteorological data have been received from synoptic stations based on daily, monthly, and annually trend from iran meteorological organization (imo) at kurdistan  province and then homogeneity of data ...
