this paper investigates the removal of iron and zinc from aqueous solution with dairy wastewaterin three different biomasses such as lactobacillus delbrueckii ssp bulgaricus (lb-12), streptococcus thermophillus(stm-7) and a combination of both this bacteria culture (yc-380) and the optimization of removal efficiencyusing minitab program. a full 23 factorial design of experiments was applied to ...

The tribe Sophoreae sensu Polhill [9,10] is a large and diverse assemblage comprising the ancient and primitive ancestral stocks of Papilionoideae. The most frequent chromosome basic numbers in this tribe are x = 11 and x = 9 but chromosome numbers range from x = 8-14 are also known. In this study chromosome numbers and karyotype variation of Iranian members of tribe Sophoreae are reported. Ira...

Multi detector-row computed tomography with 64 data acquisition systems are widely used for coronary CT angiography with an electrocardiograph (ECG) gated helical scan (HS). Step and shoot with ECG gated non-helical scan (snap shot pulse: SSP) could reduce exposure dose but banding artifact-like discontinuity was observed between adjacent slabs on volume rendering (VR) and curved planner recons...

PURPOSE The purpose of this study is to determine whether the type of operation, sphincter sparing procedures (SSP) or abdomino-perineal resection (APR) for primary adenocarcinoma of the rectum at or below the peritoneal reflection affects survival and recurrence after curative surgery. MATERIAL AND METHODS A prospective controlled study of seventy nine patients with low rectal carcinoma was ...

As two kinds of solid wastes, waste tires and steel slag have caused serious threats to the environment. Both tire rubber (WTR) powder (SSP) can improve performance asphalt, while indexes modification mechanism modified asphalt are not clear. In this paper, with SSP WTR was prepared, its evaluated. The physical properties WTR, including penetration, softening point, viscosity, were investigated...

In developing algorithms that dynamically changes the structure and weights of ANN (Artificial Neural Networks), there must be a proper balance between network complexity and its generalization capability. SEPA addresses these issues using an encoding scheme where network weights and connections are encoded in matrices of real numbers. Network parameters are locally encoded and locally adapted ...

In this dissertation research, I try to deepen the understanding of the logic and history behind the science of science policy approaches and to substitute for this scientific evidence-based science policy model an evidence-critical and -informed model in which scientific and democratic claims are promoted simultaneously. The science of science policy, or what I call the scientizing science pol...

In recent decades, porous asphalt has been extended for surface drainage in various regions throughout the world. The permeability of porous asphalt has an important role in the performance of asphalt pavements in the rainy weather. The most remarkable problem related to the porous asphalt is its short service time. Considerable efforts have been made to enhance the mechanical properties of por...

In this paper we study the efficiency of Strong Stability Preserving (SSP) Runge–Kutta methods that can be implemented with a low number registers using their Shu–Osher representation. SSP have been studied in literature and stepsize restrictions ensure numerical monotonicity found. However, for some problems, observed are larger than theoretical ones. Aiming at obtaining additional properties ...
