in order to examine the impact of pure and mixed planting on the production of grasses and also the biological control of weeds an experiment was conducted in the research farm of alashtar city of lorestan province between the years 1391 and 1392. this experiment within the design of complete random blocks (rcbd) with 6 protections which included 100:0 (rouph pea pure planting) 0:100 (pure plan...
Organic farming provides many benefits in Indonesia: it can improve soil quality, food quality and soil carbon sequestration. This study was designed to compare soil carbon sequestration levels between conventional and organic rice farming fields in west Java, Indonesia. The results from soil analysis indicate that organic farming leads to soil with significantly higher soil carbon storage capa...

Land use change as the most important destructive factor in natural ecosystems is a globally problem that changes soil properties. Therefore, correct management and recognition of change aspects on each component of the ecosystem is necessary. This process causes land destruction, ecosystem instability, soil erosion, and more biological threats. Due to increasing land use conversion from rangel...

objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
a novel ultra wideband microstrip bandpass filter using radial stub loaded resonator and interdigital coupled lines is presented in this paper. the radial stub loaded resonator and decagonal patch form a resonator named m to create tuneable multiple notches in the passband for suppression wlan interference. to realize sharp roll-off, two adjustable transmission nulls are located at the lower an...
quantitative soil quality assessment in different land uses at some parts of south eastern of qazvin
assessment of soil quality is one of the most useful tools for evaluation the soil management condition and different land uses. quantity indices of soil quality are most suitable methods for determination and comparison of soils quality. in this study soil quality indices and selection methods of effective soil properties were compared for evaluating the soil quality in different land uses. se...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
