Microwave Assisted, Sequential Two-Step, One-Pot Synthesis Of Novel Imidazo[1,2-A]Pyrimidine Containing Tri/Tetrasubstituted Imidazole Derivatives, Tuğba Güngör
Turkish Journal of Chemistry
A series of novel imidazo[1,2-a]pyrimidine containing tri/tetrasubstituted imidazole derivatives (1-10) has been synthesized via sequential two-step, one-pot, multicomponent reaction using imidazo[1,2-a]pyrimidine-2-carbaldehyde, benzil, primary amines, and ammonium acetate catalyzed by p-toluenesulfonic acid under microwave-assisted conditions. The results showed that target compounds can be obtained from a wide range of primary amines bearing different functional groups with moderate to good yields (46%-80%) under optimum reaction conditions. This method provides a green protocol for imidazo[1,2-a]pyrimidine containing tri/ tetrasubstituted imidazole derivatives due to ethyl alcohol as a green solvent, microwave irradiation as a greener heating method and one-pot multicomponent reaction as a green technique. …

Turkish Journal of Botany
Halopeplis perfoliata, a succulent halophyte of coastal marshy habitats, was grown in a greenhouse to study its adaptive responses in terms of growth, osmoregulation, and N-metabolism following one-month exposure to salinity (0, 150, 300, and 600 mmol L-1 NaCl). Biomass was optimal in 150 mmol L-1 NaCl with unaltered malondialdehyde (MDA) levels. On the other hand, biomass remained comparable to non-saline control with some increase in MDA in 300 and 600 mmol L-1 NaCl. Osmotic potential (?S ) was maintained up to 300 mmol L-1 NaCl that correlated with an increase in succulence (SC) and lower water deficit (WD), whereas …

Novel Heat Index Models For Subtropical Region Based On Daily Milk Production Incrossbred Holstein Cows, Neeraj Kashyap, Atish Kumar Chakravarty, Bharti Deshmukh
Turkish Journal of Veterinary & Animal Sciences
The quantification of the effect of heat stress imposed due to higher rate of heat gain on animal production is a prerequisite while estimating effects of heat stress. Temperature humidity index (THI) models developed empirically using meteorological parameters have been utilized as an indicator of heat stress. This study attempted to develop a heat index model with respect to productivity of the crossbred Holstein cows. More than 1.23 million daily milk yield records of 1860 crossbred cattle spread over a duration of 30 years were utilized. Statistically significant (p < 0.0001) partial regression coefficients were estimated as 0.0748 ± 0.0009 for dry bulb temperature (T$_{db}$) and -0.2228 ± 0.0011 for wet bulb temperature in model 1, -0.0182 ± 0.0005 T$_{db}$ and -0.1205 ± 0.0006 for vapour pressure in model 2, -0.0150 ± 0.0006 for Tdb and -0.1151 ± 0.0006 for dew point temperature in model 3 while as -0.1283 ± 0.0004 for T$_{db}$ and -0.0394 ± 0.0002 for relative humidity in model 4. The ratio of the partial regression coefficients of meteorological parameters (ß2/ß1) was -2.9791 in model 1, 6.8739 in model 2, 7.6731 in model 3 and 0.3073 in model 4. The developed THI models are based on the effect of meteorological parameters on daily productivity of the dairy animals, so the weightages to meteorological parameters were contrastingly different than the reported THI models. These models may successfully be used to evaluate the impact of heat stress on crossbred Holstein cows with respect to milk productivity and many other traits.

A fracture that does not unite in nine months is defined as nonunion. Nonunion is common in fragmented fractures and large bone defects where vascularization is impaired. The distal third of the tibia, the scaphoid bone or the talus fractures are furthermore prone to nonunion. Open fractures and spinal fusion cases also need special monitoring for healing. Bone tissue regeneration can be attained by autografts, allografts, xenografts and synthetic materials, however their limited availability and the increased surgical time as well as the donor site morbidity of autograft use, and lower probability of success, increased costs and disease transmission and …

Allicin, one of the most important flavor compounds in garlic bulbs, is affected by genotypic characteristics modified by ontogenesis, environmental conditions, fertilization practices, and storage duration. Therefore, the effects of fertilization practices and cultivar on garlic yield and allicin content in garlic bulbs were evaluated at harvest and during storage. One autochthonous (Ptujski spomladanski) and three commercial cultivars (Garcua, Gardacho, and Gardos) were used, and three fertilization treatments (N90S0 - 90 kg N ha-1, N90S60 - 90 kg N ha-1 +60 kg S ha-1, and N0S0 - control) were performed during two growing seasons. After the harvest, 32 bulbs per …
