BACKGROUND Comparisons of follicular development and hormonal profile in the same women during and after lactational amenorrhoea (LA) are scarce. We report follicular growth, pituitary and ovarian hormone serum levels in the same women during LA and in follicular phases after resumption of menstrual cyclicity. METHODS Serum samples were obtained from 10 women during LA between days 60 and 89 ...

Income alone cannot ensure environmental sustainability. As such, different economies have relied on regulations to preserve the quality of their environment. The efficiency such degradation is still unclear in developing countries culpable for lax regulations. this study explores effect ecological footprint (EFP) MINT (Mexico, Indonesia, Nigeria, Turkey) from 1980-2016. results suggest that en...

The effect of hydration on the lowest vertical ionization energy (VIE) of phenol and phenolate solvated in bulk water was characterized using the equation-of-motion ionization potential coupled-cluster (EOM-IP-CCSD) and effective fragment potential (EFP) methods (referred to as EOM/EFP) and determined experimentally by valence photoemission measurements using microjets and synchrotron radiation...

Equine-assisted therapy has become an increasingly popular complementary mental health treatment approach, but there is limited empirical research assessing the effectiveness of this practice. In particular, equinefacilitated psychotherapy has many potential benefits for the treatment of trauma in youth. The purpose of the proposed study was to investigate changes in levels of post-traumatic st...

در این نوشتار، بررسی پارامتریک مدل R‌H‌T و واسنجی پارامترهای آن در شبیه‌سازی مسائل ضربه‌ی بتن در نرم‌افزار اتوداینپانویس{A‌U‌T‌O‌D‌Y‌N} ارائه شده است. این مقادیر به عوامل معادله‌ی حالت و مدل‌های مقاومت، شکست و فرسایش آنها نسبت داده می‌شوند. در این نوشتار، با توجه به نیاز به مدل‌سازی پرتابه، مدل جانسون ـ کوک معرفی شده است. بعد از معرفی مدل‌ها و زیرمدل‌های آن، تحلیل یک نمونه‌ی تجربی ارائه و مطالع...

Emotional facial palsy (EFP) commonly results from anterolateral thalamic or striatocapsular infarcts. Its occurrence in brainstem lesions is uncommon, with previously reported cases being restricted to superior cerebellar artery infarction (3 cases). We report an unusual case of EFP ipsilateral to an anterior inferior cerebellar artery infarction, which opens new insights into the facial corti...

In cucurbits, phloem latex exudes from cut sieve tubes of the extrafascicular phloem (EFP), serving in defense against herbivores. We analyzed inducible defense mechanisms in the EFP of pumpkin (Cucurbita maxima) after leaf damage. As an early systemic response, wounding elicited transient accumulation of jasmonates and a decrease in exudation probably due to partial sieve tube occlusion by cal...

Abstract Based on AUTODYN-3D finite element analysis platform, the SPH algorithm is used to simulate forming characteristics of Al/PTFE reactive Explosively Formed Projectile (EFP). The evolution behaviors and distribution morphology, velocity, density, temperature field during EFP were analyzed. Numerical simulation results show that shaped charge can form stable EFP, overall density decreases...

Solvatochromic shifts of the electronic states of a chromophore can be used as a measure of solute-solvent interactions. The shifts of the electronic states of a model organic chromophore, p-nitroaniline (pNA), embedded in solvents with different polarities (water, 1,4-dioxane, and cyclohexane) are studied using a hybrid quantum mechanics/molecular-mechanics-type technique in which the chromoph...
