In this paper, a technique to generate expander graphs using Cellular Automata (CA) has been presented. The special class of CA, known as the Two Predecessor Single Attractor Cellular Automata (TPSA CA) has been characterized. It has been shown that the expander graphs built using the TPSA-CA are promising and lead to the development of strong one-way functions. The paper proposes an efficient ...

Lakes provide various ecosystem services that support biotic habitats and human life. In contrast, many lakes in the world are degraded due to pollutant supply from surrounding areas activities lake. Lake Toba, which is largest lake Indonesia, has indicated a polluted condition. However, source load of each not yet known. A study been conducted determine nutrient organic levels entering represe...

1. Inhibition of creatine kinase is known to suppress cardiac contractile reserve in intact hearts, although the underlying mechanism has not been elucidated. 2. The present study was designed to examine whether cardiac depression induced by creatine kinase inhibition was due to action at the level of the essential contractile element, namely cardiomyocytes. Adult rat cardiomyocytes were perfus...

Rubber mats offer a possibility to increase lying comfort for sows with positive effects on sow lying behavior and health. However, until now, no information has been reported about the relationship between the softness of rubber mats and the pressure load on certain body areas of sows. We used a total of 68 (40 multiparous, 28 primiparous) German Landrace × German Landrace sows with a BW withi...

PURPOSE Hypoxia is associated with malignant progression and poor outcome in several human tumors, including soft tissue sarcoma. Recent studies have suggested that carbonic anhydrase (CA) IX is an intrinsic marker of hypoxia, and that CA IX correlates with poor prognosis in several types of carcinoma. The aim of this study was to quantify the extent of CA IX expression and to investigate wheth...

The study area is a part of the Sanandaj- Sirjan metamorphic belt. The Hamadan metamorphic rocks can be divided into three groups including regional metamorphic rocks, contact metamorphic rocks and migmatites. Garnet crystals are usually common in all of the metamorphic rocks (except for slates and phyllites) and in the igneous rocks (i.e. aplite, pegmatite and monzogranite). These garnets, fro...
