soil erosion by water is the main factor of land degradation, particularly in semi-arid regions where soil productivity is usually low and lowering soil quality can severely decrease crops yields. this study was done in an area of 900 km2 in the semi-arid agricultural region of hashtroud in northwestern iran to determine the relationship between soil productivity and soil erodibility. wheat gra...

Abstrak. Infiltrasi merupakan salah satu informasi penting dari keadaan suatu lahan. Laju infiltrasi kecepatan air yang masuk kedalam tanah persatuan waktu dan apabila laju telah mencapai maksimum maka ini dinamakan dengan kapasitas infiltrasi. perlu diukur untuk mengetahui kadar bawah (perkolasi). Perhitungan secara pengukuran menggunakan model Green-Ampt dilakukan ada pada lahan, serta memban...

At present, the PC class of machine equipped with a modem and connected to the public switched telephone network (PSTN) finds many applications; access to electronic mail services, access to office computers by home-workers, occasional access to a mainframe from an isolated office, etc. Two developments are coinciding which will affect this usage; PCs are being upgraded into much more sophistic...

Background: Local infiltration analgesia pumps have been increasingly used to provide postoperative pain relief. However, their flow rate over time may not be reliable and accurate which can pose concerns regarding the achievement of the desired therapeutic level. We sought to find out in vitro if the flow rate of two elastomeric infusion pumps when combined with two types of wound catheter is ...

Infiltration rate of water into the soil depends on the factors such as rock and litter cover, canopy cover, rainfall intensity, coarse material, land slope, soil texture and amount of initial soil moisture. The most important factors that are effective in the water infiltration rate of rangelands are livestock trampling and vegetation reduction due to the overgrazing. In present study, through...

Infrared (IR) light is invisible to humans, but cameras are optically sensitive to this type of light. In this paper, we show how attackers can use surveillance cameras and infrared light to establish bi-directional covert communication between the internal networks of organizations and remote attackers. We present two scenarios: exfiltration (leaking data out of the network) and infiltration (...

Floodwater spreading for the artificial recharge of groundwater (ARG) is a logical alternative to build large dams for water resources management in dry environments so that it not only enhances water security, but also reclaims the degraded land due to the settlement of suspended load on the spreaders. However, translocation of very fine clay minerals existing in floodwater decreases the infil...
