CONVEXITY PROPERTIES OF A NEW GENERAL INTEGRAL OPERATOR OF p-VALENT FUNCTIONS

In this paper, we introduce a new general integral operator and obtain the order of convexity of this integral operator

A New Generalization of the Poisson Kernel

The purpose of this paper is to give a new generalization of the Poisson Kernel in two dimensions and discuss an integral formula for this.</p

Coefficient Estimates for Initial Taylor-Maclaurin Coefficients for a Subclass of Analytic and Bi-Univalent Functions Defined by Al-Oboudi Differential Operator

We introduce and investigate an interesting subclass Σλ,δ(n,β;h) of analytic and bi-univalent functions in the open unit disk . For functions belonging to the class Σλ,δ(n,β;h), we obtain estimates on the first two Taylor-Maclaurin coefficients a2 and a3

Faber polynomial coefficient estimates of bi-univalent functions connected with the qq-convolution

summary:We introduce a new class of bi-univalent functions defined in the open unit disc and connected with a $q$-convolution. We find estimates for the general Taylor-Maclaurin coefficients of the functions in this class by using Faber polynomial expansions and we obtain an estimation for the Fekete-Szegö problem for this class

Convexity and Spirallikeness Conditions for Two New General Integral Operators

We define two new general integral operators for certain analytic functions in the unit disc and give some sufficient conditions for these integral operators on some subclasses of analytic functions

Zooplankton of Beyhan Dam Lake (Elazığ, Turkey)

Seasonal variations of the zooplankton were studied in Beyhan Dam Lake between March 2011 and February 2012. Samples were collected from 2 different stations basis with plankton net, both horizontally and vertically. In Beyhan Dam Lake 32 zooplankton species were identified. Zooplankton samples were consisted of 93.38% Rotifera, 3.99% Cladocera, and %2.63 Copepoda, including 24, 5, and 3 taxa, respectively. Rotifera was the dominant group of zooplankton with respect to species numbers, frequency of occurrence, and density. All of the zooplanktonic species have been detected for the first time in Beyhan Dam Lake with this study. Some chemical and physical parameters as pH, dissolved oxygen, water temperature were also measured during the research.Beyhan Baraj Gölü zooplanktonu’nun mevsimsel değişimi Mart 2011- Şubat 2012 tarihleri arasında incelendi. Zooplankton örnekleri 2 farklı istasyondan plankton ağıyla hem horizontal hemde vertical olarak toplandı. Baraj Gölü’nde toplam 32 zooplankton türü teşhis edildi. Göldeki zooplanktonik organizmaların sayısal (birey/m³) olarak % 93.38’ini Rotifera, % 3.99’nu Cladocera ve % 2.63’ünü Copepoda türlerinin oluşturduğu belirlendi. Rotifera grubundan 24, Cladocera grubundan 5, Copepoda grubundan ise 3 takson bulundu. Rotifera grubu tür sayısı, ortaya çıkış sıklığı ve yoğunluk bakımından zooplankton içinde baskın grubu teşkil etmiştir. Beyhan Baraj Gölü’ndeki tüm zooplanktonik türler ilk kez bu çalışma ile teşhis edildi. Çalışma boyunca pH, çözünmüş oksijen, su sıcaklığı gibi bazı fiziksel ve kimyasal parametreler de ölçüldü
