cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
the quest for power has formed much of the world history especially in 20th and 21st centuries. oil (energy) particularly after industrial revolution has been a tool for conquest and power and has been transformed to a geopolitical issue. from a geopolitical point of view this has been the case for the last two centuries in central asia and caucasus. central asia and caucasus has always been...
in order to study the effects of different sowing dates on yield potential of cumin ecotypes and to appoint the best sowing dates of cumin at kerman, the present experiment was performed base on rcbd with split plot arrangement and 3 replications during growing season of 2011-2012. different sowing dates (25th december, 9th january, 24th january, 8th february and 23th february) as main plot, an...

Species living in comparable habitats often display strikingly similar patterns of specialization, suggesting that natural selection can lead to predictable evolutionary changes. Elucidating the genomic basis underlying such adaptive phenotypic changes is a major goal in evolutionary biology. Increasing evidence indicates that natural selection would first modulate gene regulation during the pr...
A study was conducted to investigate structural and functional modifications in three differently adapted ecotypes of Aeluropus lagopoides (Linn.) Trin. ex Thw. under saline conditions. Two ecotypes were collected from moderately saline Bailahwala Dahar (BD) and heavily salt-affected Ladam Sir (LS), respectively while one ecotype was selected from least saline Derawar Fort (DF), which was consi...
The aim of this thesis was to increase our knowledge about the effects of seed origin on the timing of height growth cessation and field performance of silver birch (Betula pendula Roth) from different latitudes, with special attention paid to the browsing damage by moose in young birch plantations. The effect of seed origin latitude and sowing time on timing of height growth cessation of first...
tourism , today as one of the ways to make money, create jobs , and social and political interactions is considered. this paper aims to examine the strengths and weaknesses of tourism development in mahmoud abad ( mazandaran ). the research method in this study is " descriptive - analytical " and to collection of data used field methods such as questionnaires and documentation - library. the sa...
Ecotypes are the result of ecological differentiation at early stages speciation. Adaptation to soil conditions offers arguably best examples local adaptation in plants. Two sympatric ecotypes, with either a red or green abaxial leaf surface, were found without clear geographical isolation Phalaenopsis pulcherrima, Southeast Asia endemic and endangered orchid. The ecotype has higher water conte...
