Abstract:
Zeta Tau (HD 37202) is a well known Be/shell star of spectral type B1 IVe and vsin(i) = 220 km/sec (Slettebak 1982). Its visual and UV variability have been studied extensively (Heap 1975; Hubert-Delplace and van der Hucht 1978; Hubert-Delplace et al. 1983; Dawanas and Hirata 1984; Harmanec 1984). Zeta Tau has also been found to be a binary with an orbital period of 132.97 days (Harmanec 1984). Irregular light variations have been observed (Hoffleit 1982) and long term variations not associated with the 132.97 day period have also been seen (Hubert-Delplace et al. 1983).

Abstract:
Теорема Воронина утверждает, что дзета-функция Римана $\zeta(s)$ универсальна в том смысле, что все аналитические функции, которые определены и не имеют нулей в правой половине критической полосы, приближаются сдвигами $\zeta(s+i\tau)$, $\tau \in \mathbb{R}$. Известны также некоторые результаты о приближении сдвигами $\zeta(s+i\varphi(\tau))$ с некоторой функцией $\varphi(\tau)$. В статье получено, что аналитическая функция, не имеющая нулей в полосе $1/2+1/(2\alpha)<\operatorname{Re} s<1$, приближается сдвигами $\zeta(s+i\log^\alpha \tau)$ с $\alpha >1$.

AbstractIn the paper we deal with self-approximation of the Riemann zeta function in the half plane $\operatorname {Re} s\gt 1$ and in the right half of the critical strip. We also prove some results concerning joint universality and joint value approximation of functions $\zeta (s+\lambda +id\tau )$ and $\zeta (s+i\tau )$.

Abstract:
Нехай $\zeta=(\zeta_n)$ - комплексна послідовність нульового роду з показником збіжності $\tau$, $N(r)$ - її усереднена лічильна функція, $\pi(z)=\prod\bigl(1-\frac{z}{\zeta_n}\bigr)$ - канонічний добуток Вейєрштрасса, а $M(r)$ - максимум модуля цього добутку. Відомо, що тоді виконується нерівність Валунда-Валірона$$\limsup_{r\to+\infty}\frac{N(r)}{\ln M(r)}\ge w(\tau),\qquad w(\tau):=\frac{\sin\pi\tau}{\pi\tau},$$і ця нерівність є точною. В роботі доведено, що для більшості (у ймовірнісному сенсі) послідовностей $\zeta$ сталу $w(\tau)$ в нерівності Валунда-Валірона можна замінити сталою $w\le

Abstract:
Принцип инвариантности для обобщенных процессов восстановления распространяется (в смысле асимптотической эквивалентности) на область умеренно больших и малых уклонений. Предполагается, что "управляющий" процессом вектор $(\tau,\zeta)$ удовлетворяет некоторым моментным условиям (например, условию Крамера), а его компоненты $\tau$ и $\zeta$ либо независимы, либо линейно зависимы. Названное распространение имеет место, в частности, и для случайных блужданий.

Abstract:
The Epstein zeta function $Z(s)$ is defined for Re$s > 1$ by \[Z(s)=\sum_{m,n=-\infty, (m, n)\neq (0, 0)}^\infty \frac{1}{(am^2−bnm+cn^2)^s}\] where $a$, $b$, $c$ are real numbers with $a>0$ and $b^2 - 4ac<0$. $Z(s)$ can be continued analytically to the whole complex plane except for a simple pole at $s =1$. Simple proofs of the functional equation and of the Kronecker "Grenz-formel" for $Z (s)$ are given. The value of $Z(k)$($k =2, 3, \cdots$) is determined in terms of infinite series of the form \[\sum_{n=1}^\infty\frac{\cot^r n\pi\tau}{n^{2k-1}} (r=1, 2, \cdots, k)\] where $\tau=(b

Nanotechnology as a science is emerging rapidly. As materials are synthesized and utilized at the nanometer size scale, concerns of potential health and safety effects are arising. In an effort to elucidate the physicochemical characteristics of nanoparticles influential in toxicological studies, surface properties of metal oxide and carbonaceous nanoparticles were measured. These properties include zeta potential, dissolution and surface-bound chemical components. Subsequently, the role of these properties in oxidative stress was examined in vitro.

Abstract:
Water injection has been practiced to displace the hydrocarbons towards adjacent wells and to support the reservoir pressure at or above the bubble point. Recently, waterflooding in sandstone reservoirs, as secondary and tertiary modes, proved to decrease the residual oil saturation. In calcareous rocks, water from various resources (deep formation, seawater, shallow beds, lakes and rivers) is generally injected in different oil fields. The ions interactions between water molecules, salts ions, oil components, and carbonate minerals are still ambiguous. Various substances are usually added bef

Common sunflower is a competitive annual native dicot found in disturbed areas, on roadsides, dry prairies, and in row crops. Common sunflower is a competitive weed, but little data exist on interference, economic impacts, and competition in field corn. Field studies were conducted in 2006 and 2007 to 1) define the density-dependent effects of common sunflower competition with corn; 2) define the necessary weed-free periods of common sunflower in corn; 3) evaluate common sunflower control with herbicides; 4) and define the economic impact of common sunflower interference with corn.

Abstract:
A billion tons per year of genetically modified corn residues are soil incorporated having both direct and indirect effects on the belowground environment, soil carbon (C) sequestration, and nutrient cycling. If Bt genetic modification has non-target effects on corn stover structural/non-structural carbohydrate and nitrogen (N) concentrations, then the degradation rate of Bt-corn stover may be different than that of non-Bt isolines, possibly influencing soil C storage and N mineralization. Thus, this research focused primarily on the comparison of C and N mineralization of corn stover in soil

Abstract:
Helicoverpa zea is one of the most costly insect pests of food and fiber crops throughout the Americas. Pyrethroid insecticides are widely applied for control as they are effective and relatively inexpensive; however, resistance threatens sustainability because alternative insecticides are often more expensive or less effective. Pyrethroid resistance has been identified since 1990 and monitoring has utilized cypermethrin in the adult vial test, but resistance mechanisms have not yet been elucidated at the molecular level. Here we examined field-collected H. zea males resistant to cypermethrin
