The chemical regulation of respiration in various species of reptiles has earlier been studied by Siefert (1896), Babak (1914a, b), v. Saalfeld (1934), Vos (1936), Boelaert (1941,1942), Randal, Stullken & Hiestand (1944), and B. Nielsen (1961). A survey of the literature was given by Vos (1936). The present work deals with the effect of different concentrations of O2 in the inspiratory air on r...

We present solutions of the holomorphic anomaly equations for compact two-parameter Calabi-Yau manifolds which are hypersurfaces in weighted projective space. In particular we focus on K3-fibrations where due to heterotic type II duality the topological invariants in the fibre direction are encoded in certain modular forms. The formalism employed provides holomorphic expansions of topological s...

Wearing face coverings outside should be normalised because it may reduce transmission of SARS-CoV-2 in some situations—and encourage mask wearing indoors, where risks are greater—say Babak Javid, Dirk Bassler, and Manuel B Bryant. But Muge Cevik, Zeynep Tufekci, Stefan Baral argue that outdoor contributes very little to overall infection rates efforts ...

Geologically, Shahr-e-Babak playa is located in the southeast of Sanandaj-Sirjan Zone. Based on mineralogical and scanning electron microscopy (SEM) studies, in the studied playa major mineralogical phases include hallosit, kaolinite, illite, quartz, calcite and gypsum. Based on geochemical data, the average aluminum oxide values is 13/93% , silicon oxide is 39/53% and the average of volatiles ...

Objective: Metal concentrations in 53 soil samples of Shahr-e-Babak were determined.  Methods: Assessment of enrichment factor and geo-accumulation index revealed higher degree of contamination of Cd, Pb, and Cu in soil samples. Moreover, results of metal fractionation study revealed high amount of Cd and Pb are associated in weakly bounds may lead to environmental risk of these metals.  Result...

This research is action research, because the was conducted to solve learning problems in classroom. also includes descriptive it describes how a technique applied and desired results can be achieved. The observation divided into two rounds, namely rounds 1 2, where each round given same treatment (same flow of activities) discussion sub-subjects which ended with formative test at end round.

Pleistocene basaltic lava flows, consisting of trachybasalt and basaltic trachyandesite, cover an area north-northwest of Shahre-Babak in southeastern Iran. The whole rock chemistry indicates that the lavas are dominantly alkaline and mildly calc-alkaline. Variation diagrams of SiO2 with major and trace elements are consistent with fractional crystallization processes involving olivine, pyroxen...
