Groundwater Assessment for the NW of Auja Tamaseeh Basin in Tulkarem Area, West Bank  [PDF]
Nizar Samhan, Marwan Ghanem
Journal of Water Resource and Protection (JWARP) , 2012, DOI: 10.4236/jwarp.2012.46047
Abstract: The study aims to assess groundwater in Auja—Tamaseeh basin in Tulkarem area—West Bank. A steady state calibration flow model as well as solute transport model were built using the visual Modflow software. A stress period of 10 years (2005 - 2015) was assigned to study its tendency to contamination. The model results show that there is a pollution risk due to the human activities in the area. The groundwater situation will be harmful if there is no action done by the water-decision makers to preserve the aquifers from deterioration and contamination.
Feasibility of Protection Zones for Water Resources in Arid Areas: Case Study; Duyuk Nueimah Shosa Springs, Jericho, Palestine  [PDF]
Marwan Ghanem, Mahmoud Hammad
Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.62013
Abstract: Urbanization and different human-economic activities put increasing pressure on the ground water quality, which is considered as the main drinking water resources in Palestine. Protecting the spring water resources in Palestine is one major issue for the continuity of the availability of the water resources. An economic feasibility study was conducted for the Nuewimah-Shosha-Dyuk spring system in order to assess the economical factor for the induced methodology of the protection zones. The spring system has multiple users from different sectors (i.e., domestic, agriculture, commercial and public use) and multi-year cost benefit analysis technique used to show the feasibility of water protection zones on the long run. The study shows that even in arid areas in Palestine, small quantities are derived from springs-implementation of water protection zones is still feasible; the results of this study emphasize on importance and feasibility of water resources protection zones.
Spring Water Qualitative Assessment in Mountainous Areas, Case Study: Soreq Catchment/Ramallah/West Bank  [PDF]
Hassan Jebreen, Marwan Ghanem
Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.711069
Abstract: The hydrochemical characteristics of spring waters in the Soreq-Catchment were determined to identify pollutants in the springs. The ion concentrations were within the allowable WHO limits except two springs located within the center of the populated areas. The water of most of the springs is contaminated with fecal coliform and total coliform. The concentration of nitrate shows moderate values below the WHO limits. The springs in the study area show higher concentrations of heavy metals (Zn, Cd, Mn, As, Co, Cu, Ni, Pb, Al, Fe, and V) exceeding the permissible standards set by WHO (2007). Most springs in the study area are of water type (Ca-Mg-HCO3-). Piper’s classification ranges from normal earth alkaline water with prevailing bicarbonate and chloride in both seasons. Comparing the quality of spring water with standards for different uses proved that some springs are unsuitable for human drinking purposes.
Groundwater Pollution Due to Pesticides and Heavy Metals in North West Bank  [PDF]
Marwan Ghanem, Subhi Samhan, Erick Carlier, Wasim Ali
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.24049
Abstract: This study aims at determining the quantitative effect of pesticides including 2, 4-D dichlorphenoxy acetic acids, Paraquat, Atrazine (2-chloro-4-ethylamino-6-isopropylamino-striazine), and MCPP 2-(2-Methyl-4-chlorophenoxy) pro-panioic acid on groundwater quality due to agricultural in Jenin and Tulkarem, northern part of the West Bank. The concentrations of pesticides in Jenin was found to be higher than those in Tulkarem where the majority of the samples taken had concentration 10 µg/L. It is concluded that the contamination of the tested wells was due to pesticides and not wastewater disposal, since most of the samples were free from pathogenic indicators. Results revealed that using these wells for drinking purposes has a potentially high health risk. This is mainly due to the uncontrolled industrial and agricultural activity as well as the lack of monitoring. Concentrations of heavy metals including cadmium (Cd), lead (Pb), iron (Fe), zinc (Zn), chromium (Cr) and copper (Cu) were also quantitatively determined for the same period extending from April, 2004 to May, 2005. Concentrations of Pb and Cr in most of the tested wells in Tulkarem complied with the WHO guideline; while nitrate (NO3) and potassium (K) concentrations exceeded the permissible concentra-tions.

Hussein Al-Rimmawi, Marwan Ghanem, Ibrahim Shalash
Journal of Water Resource and Protection (JWARP) , 2010, DOI: 10.4236/jwarp.2010.24040
Abstract: Linear regression and moving averages were used to analyze the patterns of rainfall in eight station in the district of Ramallah and Al-Bireh for the period from 1950’s to present. Data analysis showed that a ten years period variability of rainfall but with consistency. It also showed that rainfall in the studied area is not decreasing as mentioned in several previous studies. This area is mountainous and enjoys the Mediterranean climates.
Assessment of Artificial Recharge Test in Jeftlik – Faria Area, West Bank  [PDF]
Marwan Ghanem, Amer Marei, Heinz Hoetzl, Leif Wolf, Wasim Ali, Amjad Assi
Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.33024
Abstract: An artificial recharge test site was selected in the Jeftlik area of the foot prints of the Faria basin, in the Upper Jordan Rift Valley. The artificial pond infiltration type of 26 meters diameter and 2.85 meters depth was used. It is a hyperbolic form of 500 cubic meters volume. The integration parameters of hydrogeological settings, hydrochemical characteristics of allocated water bodies, geophysical investigations and the potentiality of the aquifer system in the area were used for the test area selection. The test site area lies within the shallow Pleistocene aquifer of 30-50 meters saturated thickness. One groundwater well of 19 m distance and two groundwater wells of 1 km far distance were used for the system monitoring. The filled water in the test system comes from the wadi water floods brought by 1.5 km of open canal. The sub-catchment is of 3 km2. The recharge rate within the Pleistocene aquifer was determined. This experiment is tested for the water quality type fillings of the first flushing water floods, the water flood in the middle of the winter season and the pumped water from other wells far away from the experiment.
Perceived Family and School Rejection and Adolescents’ Psychological States  [PDF]
Marwan Dwairy
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.26083
Abstract: This study deals with the perceived acceptance-rejection of male and female adolescents at home and at school and their association with the psychological states experienced by them. A sample of 350 female and 220 male 10th grade students filled out two questionnaires: Dwairy’s Rejection Scale, measuring acceptance-rejection by fathers, mothers, brothers, sisters, male teachers, female teachers, male classmates and female classmates, and the Psychological State Scale, measuring anxiety, depression, psychosomatic symptoms and conduct disorders. The results show that all perceived acceptance-rejection circuits are associated with and merged in three major factors of rejection: family, teachers, and classmates. All the factors were associated with psychological states experienced by the adolescents with a cross-gender effect. Experienced psychological states of male adolescents were associated with perceived acceptance-rejection circuits at home and at school, in particular when related to female figures, while psychological states of female adolescents were associated with male and female figures at home. The results highlight the need for a systemic approach in research.
Volumetric Overload Shocks: Why Is Starling’s Law for Capillary Interstitial Fluid Transfer Wrong? The Hydrodynamics of a Porous Orifice Tube as Alternative  [PDF]
Ahmed N. Ghanem, Salma A. Ghanem
Surgical Science (SS) , 2016, DOI: 10.4236/ss.2016.76035
Abstract: Based on clinical and experimental work two new types of volumetric overload shocks are reported: volumetric overload shock type one and type two depending on the type of fluid causing their induction. Volumetric overload shock type one is induced by sodium-free fluids such as glycine, glucose, mannitol and sorbitol and is characterized with acute dilutional hyponatraemia. Volumetric overload shock type 2 is induced with sodium-based fluids normal saline and plasma substitutes used for resuscitation of the critically ill and has no serological marker. It presents with the multiple vital organs dysfunction or failure syndrome or the adult respiratory distress syndrome. Hypertonic sodium is an effective treatment when given early adequately. The underlying pathophysiology is discussed. An alternative to Starling’s law for the capillary interstitial fluid transfer is given. Hydrodynamic of a porous orifice tube akin to capillary with a surrounding Chamber akin to the interstitial fluid space demonstrated a rapid dynamic magnetic field-like fluid circulation between the surrounding chamber and the lumen of the G tube that represent an adequate replacement for Starling’s law.

Case Study: Trends and Early Prediction of Rainfall in Jordan  [PDF]
Ali Ahmad Ghanem
American Journal of Climate Change (AJCC) , 2013, DOI: 10.4236/ajcc.2013.23021
Abstract:

Fourteen meteorological stations distributed over Jordan were selected. Data of annual and monthly rainfall amount of autumn (October and November) for a period more than 50 years were analyzed to show their relationships with the normal annual rainfall. An attempt was made to use the standard deviation values in order to have an early prediction for the annual rainfall (less or more than the normal) depending on the autumn rainfall amounts. It is found that the annual rainfall exceeded the normal when autumn rainfall amounts were more than 30 mm in Jurf El Daraweesh, Qatraneh, Safawi, and Wadi Musa, 50 mm in Mafraq, 60 mm in Amman, and 100 mm in Salt and Irbed. Regression analysis projected weak increasing trends in autumn and decreasing trends in the annual rainfall in the majority of Jordan.
