Evidence is accumulating to challenge the paradigm that biogenic methanogenesis, considered a strictly anaerobic process, exclusive archaea. We demonstrate cyanobacteria living in marine, freshwater, and terrestrial environments produce methane at substantial rates under light, dark, oxic, anoxic conditions, linking production with light-driven primary productivity globally relevant ancient group of photoautotrophs. Methane production, attributed using stable isotope labeling techniques, was...

The meteorological data such as rainfall and temperatures, covering the period between 1979 2008, has been analyzed. were simulated using geographic information systems (GIS) computer software "MATLAB". output results converted into geographical maps. Three parameters analyzed: annual mean maximum temperature, minimum during (1979–2008). analyzed also used to forecast for (2009–2018).

The objective of this study was to evaluate the extent Pseudomonas aeruginosa contamination Dental Unit Water (DUW) at a Teaching Center in Jordan.Water samples were collected from 30 dental units, 10 each three teaching clinics, namely conservative dentistry, periodontology, and prosthodontics. Samples outlet air/water syringe, high-speed handpiece water cup filler, beginning working day (before use), after 2 min flushing, midday.P. detected 86.7% (26/30) units day, 73.3% (22/30) flushing...

The thermal springs of Zerka Ma'in, with waters emerging at temperatures up to 63 degrees C, have been interest biologists already from the beginning 19th century. These waters, springing out below ground and flowing into hypersaline Dead Sea, form an isolated environment a biogeographic point view. We investigated molecular diversity cyanobacteria in springs. discovered was large, defining operational taxonomic units (OTUs) by cutoff 97% similarity; 10 major OTUs were found, including as...

Several Arab countries face numerous environmental problems in addition to climate change, desertification, and water crisis. Multiple issues related energy need be resolved. In this paper, we examine the most important topics studied, research conducted elucidate importance of problem region, including gap between increased demand a lack resources. Water include leakage, pollution, depletion We also focus on change role young people, software, educational institutions, training centers...

A process improvement in a tablet manufacturing within pharmaceutical industry was carried out based on an eco-efficiency approach. As it is one of the most energy consuming processes production line, considered. It has highest volume with complicated and long product life cycle. Data were collected inputs emissions data for stages powder direct mixing, particle size reduction, tableting. straightforward approach then used to analyze environmental impacts terms GHG emissions. Non- added...

This study examined the potential of water-food-energy nexus in Jordan, as there are strong connections between these pillars that will help to ensure a sustainable future. The focus was on dual relationship three sectors, namely water and energy, food, energy food. Currently several processes arising from problems associated with sectors ought be addressed avoid negative consequences. Increased demand, shortage supply, climate change, economic aspects, population growth among numerous...

Abstract: Objective: This study aimed to evaluate the extent of Legionella pneumophila contamination in a dental unit water line (DUWL) at Dental Teaching Centre Jordan. Methods: Ten units were sampled from each teaching clinic, namely conservative dentistry, periodontology and prosthodontics. Samples collected air/water syringe, high‐speed hand piece cup filler. Sampling time was beginning working day (before used), after 2 min flushing, midday. Results: counts ranged between 0 8.35 × 10 3...

Treated wastewater is an important component of the water resource in Jordan. As Samra treatment plant—the largest plant Jordan—discharges ~110 MCM per year secondary treated municipal to Zarqa River, and eventually Jordan Valley. This research aims at assessing impact reuse on hydrology environment most vulnerable areas within Amman-Zarqa Basin, specifically from Jerash Bridge. Historical data collected, field survey performed, chemical biological analyses are performed eleven selected...

This work suggests a solution for preventing/eliminating the predicted Sea Level Rise (SLR) by seawater desalination and storage through large number of plants distributed worldwide; it also comprises that desalinated can resolve global water scarcity complete coverage demand. level rise be prevented desalinating additional accumulated into oceans annually human consumption, while excess amount stored in dams lakes. It is SLR plants. The chosen study were Multi-Effect Desalination (MED)...

The freshwater thermal springs of Zerka Ma'in, located in Jordan the mountains Moab east Dead Sea, are densely inhabited by cyanobacteria up to highest temperature 63°C. We have investigated cyanobacterial diversity these and their outflow channels microscopic examination, culture-dependent culture-independent phylogenetic analysis, physiological studies selected isolates special interest. Both unicellular filamentous types present, we identified morphological such as Thermosynechococcus,...

In order to get on the path of sustainable development as a society whole, great transformation is required. Universities are embedded in and networked with it through various forms interaction; they influence social discourses often have decisive them. As educational institutions, universities take critical stance state our earth actively fulfill their responsibility. The German Jordanian University (GJU), like any other university, produces solid hazardous waste. A waste audit was done...

Scientific exploration of the algal and cyanobacterial flora Dead Sea its surroundings started in 1930s. The unicellular green alga Dunaliella parva is sole primary producer water column Sea. dynamics population interrelationships between physical chemical parameters lake are now well understood. Although cyanobacteria have occasionally been encountered as well, they not known to contribute significantly microbial activities lake. Dense growth found various freshwater saline, cold warm...

Bakery waste (BW) is much cheaper than barley (20 to 40% the price of barley).Bakery and grain have similar chemical composition; they contain 99 97% organic matter (OM), 1.1 1.8% fat, 18 15% neutral detergent fibre (NDF) 14.0 14.5% crude protein (CP), respectively (DM basis).The objectives this study were determine effect substituting BW for in high concentrate fattening diets lambs on nutrient intake, growth carcass characteristics.Forty Awassi (21.75±1 kg) weaned at age 65 days assigned...

Abstract Evidence is accumulating to challenge the paradigm that biogenic methanogenesis, traditionally considered a strictly anerobic process, exclusive Archaea . Here we demonstrate Cyanobacteria living in marine, freshwater and terrestrial environments produce methane at substantial rates under light dark oxic anoxic conditions, forming link between driven primary productivity production globally relevant group of phototrophs. Biogenic was enhanced during oxygenic photosynthesis directly...

The area of the Dead Sea, bordering Jordan and Israel, contains many springs with different physical chemical properties. Hot are found on eastern shore lake: Zara (the ancient Callirrhoe) tem- peratures up to 59 °C those Zerka Ma'in, 5 km inland. latter springs, mentioned by Josephus (1st century C.E.), yield fresh water a low sulfide content, near-neutral pH temperatures 63 °C. Although growth green microorganisms was already noted in 1807 German explorer ulrich Jasper seetzen, microflora...
