Each Gr-category (or categorical group) is Gr-equivalent to a Grcategory of type (Π, A, ξ), where Π is a group, A is a Π-module and ξ is a 3-cocycle of Π, with coefficients in A. In this paper, first we show that each Gr-functor induces one between Gr-categories of type (Π, C). Then we give results on the existence of Gr-functor and the classification of Gr-functors by cohomology groups H(Π, C)...

The focused lane is located on main arterial road with length 4.2 km, St. Urip Sumoharjo which known as longest most congested Makassar City. was carried out by surveying observation tree used image processing validate suspect through App. Meanwhile, cal...

while the hydrological balance of forest ecosystems has often been studied, quantitative studies on the seasonal variability of rainfall interception (i) and canopy storage capacity (s) by individual trees are less frequently reported. hence, the effects of the seasonal variation in i and s by individual persian oak trees (quercus brantii var. persica) in the zagros forests of iran were studied...

PLTU Tidore produces coal waste in the form of bottom ash or (FABA) which an average 14 tons per day 5,040 year. To reduce amount waste, can production costs and industrial namely by using as a substitute for fine aggregate. The specifications implementation this test refer to General Bina Marga 2018 specifications. compaction object is carried out 2 × 75 collisions assuming that intended heavy...

Soil contamination with heavy metals such as arsenic has harmful effects on human health and agricultural products. Arsenic (AS) is one of the heavy metals which are highly toxic and carcinogenic. This research was conducted to study the effect of organic manure on increasing the Arsenic absorption ability by Cress plant in the greenhouse of the Agriculture and Natural Resources Research Center...

The growth and mortality coefficient of Rutilus frisii kutum, were estimated using length frequency data collected in southern waters of the Caspian Sea during October 2008 to April 2009. The following population parameters were evaluated: length-weight relationship, W = 0.004L 3.258, (r= 0.976) Von Bertalanffy growth constants, W∞ (g) = 4192.3, L∞ (cm) = 70.45, K = 0.2, per year t0 = −0.75 tot...

background: over the past few years, the rapid use of high frequency electromagnetic fields like mobile phones has raised global concerns about the negative health effects of its use. adaptive response is the ability of a cell or tissue to better resist stress damage by prior exposure to a lesser amount of stress. this study aimed to assess whether radiofrequency radiation can induce adaptive r...
