Curcuma longa has well-known insecticidal and repellent effects on insect pests, but its impact on Trichoplusia ni is unknown. In this study, the compound ar-turmerone, extracted and purified from C. longa rhizomes, was identified, and its insecticidal effects, along with turmeric powder, curcuminoid pigments and crude essential oil were evaluated against this important agricultural pest. The r...

Progesterone (P) is the primary effector of LH (and by inference gonadotropin-releasing hormone) pulse frequency slowing in cycling women, but the time course of this action is unclear. We hypothesized that P administration to estradiol (E2)-pretreated women would slow LH pulse frequency within 12 h. We studied eight normally cycling women in two separate cycles (follicular phase, cycle days 7-...

BACKGROUND We sought to determine if a pre-workout supplement (PWS), containing multiple ingredients thought to enhance blood flow, increases hyperemia associated with resistance training compared to placebo (PBO). Given the potential interaction with training loads/time-under-tension, we evaluated the hyperemic response at two different loads to failure. METHODS Thirty males participated in ...

Abstract The study of graphene/poly (p-phenylene benzobisoxazole) (PBO) nanocomposites in recent years is introduced, while the research interests and application fields graphene/PBO future are prospected this review. In process polymer formation, two modification methods, in-situ polymerization blending mainly used to improve dispersion uniformity graphene PBO matrix. can be divided into surfa...

Many investment firms and portfolio managers rely on backtests (i.e., simulations of performance based on historical market data) to select investment strategies and allocate capital. Standard statistical techniques designed to prevent regression overfitting, such as holdout, tend to be unreliable and inaccurate in the context of investment backtests. We propose a general framework to assess th...

BACKGROUND Addition of a second bronchodilator from a different pharmacological class may benefit patients with moderate-to-severe chronic obstructive pulmonary disease (COPD) whose symptoms are insufficiently controlled by bronchodilator monotherapy. GLOW6 evaluated the efficacy and safety of once-daily coadministration of the long-acting β2-agonist indacaterol (IND) and the long-acting muscar...

PbOを 含有す る混合 アル カ リの光学 ガ ラスのNa+_??_K+イ オ ン交換 に 及 ぼす ガラス組成 の影 響 をEPMA,光 学顕微鏡 によ り研究 した. Al2O3/Na2O比 が1.0以 下 では, この比 の増大 に とも ないイオ ン交換の速 度が増大す ることが一般 に知 られて いるが, 本研究 のPbOを 多 く含 むガラス の場合には このAl2O3/Na2O比 の効果が ほ とん ど な い ことが わか った. これ はPb2+イ オ ンが Na+_??_K+イ オ ン交換の際にK+イ オ ンの移動 を抑 え るためであろ う. しか しPbOをAl2O3で 入れ換 えてAl2O3/Na2O比 を増 大 させ る とみかけの拡散 係数 は5倍 増大 し, Al2O3/Na2Oの 比の影 響 がみ られた. した が ってPbOを 多 く含 有す ...

Introduction: The present study aimed to evaluate the impact of PbO nano and micro-sized fillers on ordinary and heavy concretes for different photon energies. Material and Methods: The MCNPX Monte Carlo code (version 2.6.0) was used for all simulations in the present study. A model of narrow-beam geometry was validated and utilized to calcul...
