Climate change negatively affects sustainable development in Palestine, especially Jenin Gover-norate, which is the food basket for Palestine. This study identified climate variables Governorate more than 100 years, temperatures and precipitation, derived from historical data to manifestations of its impact on water re-sources agricultural sector. The groundwater wells an un-derstatement. major...

In the fall of 1999, two types of impact sprinklers were evaluated to determine the distribution of precipitation under normal operating conditions. The sprinkler types included a traditional round-patterned design (Rain Bird Maxi-Bird) and a recently developed sprinkler delivering water in a square pattern, called Square Shooter. The squarepatterned sprinkler was more precise in delivering a u...

The Complete fluidic sprinkler was originally created by China. Irrigation uniformity in no-wind conditions was studied in this paper. Radial water distribution for complete fluidic sprinkler type 10 was got by experiment. MATLAB was used to establish computation program to change the radial data into net data. Three-dimensional water distribution figures for single sprinkler and combined sprin...

BACKGROUND The main objective of this study was characterization of selected heavy metals concentrations (Lead, cadmium, copper, zinc, nickel and chromium) in groundwater used for ir-rigation in Tabriz City's countryside. METHODS After consulting with the experts of agriculture department and site survey, 38 irriga-tion water samples were taken from different farms (34 wells) without primary ...

Infected abdominal aortic aneurysms are rare, but the symptoms are prone to become severe during the clinical course, and the prognosis is poor, with a high rate of rupture [1]. There are 2 objectives in the treatment of infected aortic aneurysms: prevention of aneurysm rup‐ ture and infection control. However, it is not easy to achieve both. No guideline has been established yet, and many issu...

In the 1980s, a special compound formula was developed to suit the demands of a fire sprinkler system for life safety applications. In 1984, the first BlazeMaster® CPVC fire sprinkler systems were deployed in the United States. Since then, BlazeMaster fire sprinkler systems have been performing so successfully that 50% of all NFPA 13 applications in the US are specified with BlazeMaster pipes a...

A fire in an enclosed space, such as a room in a building, is generally called a compartment fire. To prevent the compartment fire, a sprinkler for first-aid fire-fighting is installed in rooms. However, it is difficult to determine the degree to which smoke generation and the fire spreading will be inhibited when sprinklers are on. In particular, demonstrating evacuation behavior assuming an a...

Two studies were conducted investigating the effect of injecting short acting insulin subcutaneously by means of a sprinkler needle; this needle has 14 small holes in the wall but is sealed at the tip. In the first study absorption of 8 U iodine-125 labelled Actrapid HM injected subcutaneously at two separate sites in the abdominal wall was measured in 10 patients. One injection was given with ...

Performance based methodologies are becoming increasingly common in fire safety due to the inability of prescriptive codes to account for every architectural feature. Fire Sprinkler suppression systems have long been used to provide property protection and enhance life safety. However, very few methodologies exist to account for the impact of sprinkler sprays on fire scenarios. Current methods ...

The occurence of corrosion is a potentially major problem for all sprinkler systems. It could cause a problem for the operational reliability as well as for the performance reliablity. It is of course negative for the operational reliability if corrosion causes plugged piping, clogging of control valves or simply non-opening sprinkler heads. All of which may well be the effect of uncontrolled c...
