01 Jan 2020TL;DR: In this paper, the aboveground parts (flowers + shoots + leaves) of Salvia bracteata plants were collected in the province of Kirsehir, Turkey, during the flowering stage in 2018.
Abstract: The present study was conducted with the aim of determining biological
activities of the Salvia bracteata plant, activities such as its
antioxidant, total phenolic, total flavonoid, allelopathic and antifungal
effects. To this end, aboveground parts (flowers + shoots + leaves) of S.
bracteata plants were collected in the province of Kirsehir, Turkey, during
the flowering stage in 2018. As a result of GC-MS analysis, 23 constituents
were identified, representing 96.21% of the essential oil. The major
compounds of essential oil were identified as ledol (24.12%), camphor
(15.54%) and valencene (5.64%). In ethyl acetate, methanol and hexane
extracts of S. bracteata, total phenolic content was found to be 104.63,
121.66 and 20.97 mg of GAE/g of extract, respectively, while flavonoid
content was 12.89, 10.85 and 1.13 mg of QE/g of extract, respectively. In
addition to this, DPPH radical removal activity was identified and found to
be at its highest in the methanol and ethyl acetate extracts. The TEAC
(cation radical removal activity), FRAP (iron reduction power) and CUPRAC
(copper reduction power) reduction activities of these plant extracts were
also determined. The methanol extract of S. bracteata was found to have an
allelopathic effect on Rumex crispus and Taraxacum officinale. This extract
had a weak effect on development of the mycelium of Alternaria solani
Sorauer, one of the most significant of plant-pathogenic fungi, but it was
found to be ineffective on the Sclerotinia sclerotiorum pathogen.

TL;DR: The results of the present study indicated that A and MAM breeds could be recommended for desirable carcass characteristics.
Abstract: The present study was conducted to determine the slaughter and carcass traits of male lambs of the Akkaraman (A), Morkaraman (M), Awassi (IW), Karayaka (KR), Kivircik (KV) and Middle Anatolian Merino (MAM) sheep breeds. Fattening of all lambs started when they were at 90 days at weaning and finished when they reached bodyweight of 40 kg. The cold dressing percentage of lambs of A, M, and IW breeds were significantly lower than those of KV, KR and MAM. Fat depth and muscle area were significantly greater in KV and MAM lambs than those of the other breeds. There were significant differences among breeds in shoulder, leg and lean weights. Weights of back loin in KV and MAM lambs were significantly greater than those of the other breeds. The highest values for carcass fleshiness were obtained in MAM and IW lambs, but they had a significantly lower carcass fatness score. There were significant differences among the breeds in carcass compactness and leg conformation. The results of the present study indicated that A and MAM breeds could be recommended for desirable carcass characteristics.

TL;DR: In this article, a pseudopotential plane-wave method based on density functional theory within the generalized gradient approximation for the exchange-correlation potential has been applied to study the structural, electronic, elastic and vibrational properties of the binary intermetallic Pd3V and Pt3V in the L12 phase.
Abstract: Pseudopotential plane-wave method based on density functional theory within the generalized gradient approximation for the exchange-correlation potential has been applied to study the structural, electronic, elastic and vibrational properties of the binary intermetallic Pd3V and Pt3V in the L12 phase. The optimized lattice constant, bulk modulus and its pressure derivative, independent single-crystal elastic constants and elastic wave velocities in three different directions are evaluated and compared with the available experimental and theoretical data. The polycrystalline elastic parameters, hardness coefficient, elastic anisotropy, Debye temperature are estimated. The electronic band structure, electronic total and partial densities of states, and total magnetic moment of the Pd3V and Pt3V alloys are computed and analyzed in comparison with the existing theoretical and experimental findings. Phonon-dispersion curves and their corresponding total and projected densities of states were obtained for the first time using a linear-response in the framework of the density functional perturbation theory.
