To experimentally investigate the change in air distribution in cold storage because of induce draught, a reduced scaled experimental setup is developed. Air velocity is measured by using hot wire anemometer. Air distribution is most important criteria for design and operation of cold storage chamber. Quality and life of food stuff in cold storage highly dependent on air distribution as temperature filed are likely varies as per flow of air. In this paper customization of air flow using induced duct is discussed. It has been observed that in a cold chamber air flow is heterogeneous it cause number of temperature zones in chamber, high respiration rate and various relative humidity zone, all these leads to loss of stored items through perish. An experimental setup of geometrically similar reduce scale model of cold storage (6m (l) x 4m (w) x 4m (h)) is developed by taking ratio one fourth of actual dimensions. Outcome of this work proposed that use of reverse duct to produce induce draught for enhance the air flow in farthest part of cold room, which will leads to improve the temperature distribution in chamber. Uniform air flow distribution help to reduce the loss of perishable agricultural product and increased their safe storage period

This paper presents the necessity of energy storage technologies to help the Renewable Energy Resources (RERs) power the smart grid to meet the energy demands of the future. The paper identifies the different storage techniques that can be implemented in to a smart grid and a cost-benefit analysis of the different storage techniques. While explaining these different storage techniques the following items that will be covered are size, technology, protection, advantages, disadvantages, time scale for implantation and physical location of the storage. The cost-benefit analysis of different storage technologies have also been presented in this paper, the guidelines are also presented to select a storage technique based on a given power systems problem.

Active structures have an important role in controlling fluvial systems through longitudinal and lateral tilting. The Ghezel Ozan River in northwest of Iran has responded to ongoing tectonic deformation in the basin. The study area is located in the Western Alborz zone and includes part of the Ghezel Ozan River. This paper presents the role of active structures in making active deformations via detection and characterization of fluvial anomalies and correlation with structures. The study area is characterized by association of fluvial anomalies viz. deflection, anomalous sinuosity variations and knick point in longitudinal profile. Such fluvial anomalies have been identified on the repetitive satellite images and maps and interpreted through DEM and field observations to identify active structures in the area. Some of the structures in the study area have caused the fluvial anomalies and the most active structures are surface and sub-surface faults and folds with trend of NE-SW.

An experiment was carried for evaluating the effects of moisture deficit at different growth stages in spring barley landraces under field conditions. A split plot experiment was conducted based on randomized complete blocks design with three replications. Three irrigation levels including optimal and disruption irrigations at stem elongation and heading were arranged as main plots and barely landraces with names of Abdolalikandy, Bastam, Sefid, Seyah, Shin, Hashtpar and Bayramghalasi were in subplots. Different irrigation levels and barley landraces for measured traits showed statistically significant differences. Grain yield under optimal, disruption irrigations at stem elongation and heading were 161.14, 99.8 and 128.0 g/m2, respectively. Shin and Hashtpar landraces with the lowest grain yield 88.75 and 95.91g/m2 and amounts of the least TOL 12.5, 0.59 and SSI 5.0, 0.75 at both stresses were tolerant to moisture deficit. Spike/m2 remained at final models in regression analysis at two moisture deficits. In principal components analysis, three first components explained more than 91% of total variance which they were named grain yield, physiological and morphological components, respectively. Grain yield was positively significant correlated with spike/m2 under optimal and disruption irrigations at stem elongation and heading with 0.94**, 0.90** and 0.94**, respectively. In both stresses, STI, MP, GMP and HAR indices had significant positive correlation with grain yield. In addition, spike/m2 and plant height had the most direct effects on grain yield 0.84 and 0.29, respectively
