تهدف الدراسة إلى إمكانية استخدام الرماد المتشكل من حرق الحطب و مخلفات التقليم المختلفة في إزالة قساوة المياه . تم في هذا البحث توصيف الرماد ( ناتج عن حرق مخلفات من شجرتي البلوط و السنديان ) لتحديد نسب المكونات الداخلة فيه باستخدام عدة تقانات منها XRD و مطيافية اللهب و المعايرات الحجمية و غيرها . حدد زمن خلط الطورين المثالي عبر وضع كمية محددة من الرماد إلى مياه شديدة القساوة حيث تم معايرة قساوة المياه خلال أزمنة مختلفة ( 0.5,1,2,3,4,5) ساعة و كان الزمن المثالي لخلط الطورين عند3ساعات . عينت نسب الإزالة و ذلك بتثبيت زمن خلط الطورين و بإضافة بشكل مباشر الكميات التالية من الرماد ( 0.5;1;2;3;5;7;10;15;20;25 ) غرام إلى 200 مل من مياه شديدة القساوة و تبين أن نسبة الإزالة تزداد بشكل طردي بازدياد كمية الرماد المضاف و بلغت نسبة الإزالة ما يقارب 50% عند استخدام واحد غرام من الرماد حتى الوصول إلى نسبة إزالة كاملة قدرها 100% عند استخدام 25 غرام من الرماد .
This study aims to use the ash formed from the burning of firewood and the different pruning residues to remove the hardness of water Soda ash was characterized using different techniques, including XRD,flame spectroscopy , volume titration and others. These methods aim to determine the composition of the ash and the components which are contributing to the removal process. The optimum mixing time was determined using certain amount of soda ash to the hard water and the water hardness was determined in the rang of time (0.5, 1, 2, 3, 4 and 5h) where the ideal time was 3 hours. The removal ratios were determined when the mixing time of the two phases was 3 h, and adding directly the following quantities of ash (0.5,1,2,3,5,7,10,15,20,25) g to 200 ml of highly hardened water. The removal rate was increased by increasing the amount of added ash. The removal rate was approximately 50% when 1 g of ash was used and the complete removal rate of 100% was achieved when the amount of ash was 25 g.

Ash toxicity of burning pruning residues of three plant species i.e. apple, grape and
olive was tested against adults of cowpea seed beetle Callosobruchus maculatus
(F.) (Coleoptera, Bruchidae) using the following concentrations: (5, 10, 20, 40
an
d 80) g/kg of cowpea seed. The study was carried out in incubator at fixed
temperature and humidity at Biotechnology Research Center, Al-baath University.
Readings were taken after (24, 48 and 72) h of treatment, and corrected mortality
rates were calculated and values of LC50, LC90, LT50 and LT90.

This research aims to study the effectiveness of each(ferric chloride , ash and coffee
dregs) to remove phosphorus from Lattakia Port Laboratories' waste water which is
assembled in a separate sewage pit by doing laboratory experiments on water con
taining
high concentrations of phosphorus, whether real wastewater or standard solutions of
phosphorus oxide. Where it has been experimenting with ferric chloride at doses as weight
average(FeCl3/P = (0-5)) to give effectiveness ratios(70- 80)% with determining the value
of the pH-compliant and it was noted re-releasing of phosphorus time after(10-12) hours of
the start of precipitation, beside that it has been experimenting with ash as adsorpted agent
at doses as weight average(Ash/P = (2-4.5)) to give effectiveness ratio which it had
reached to 98% where it was noted re-releasing of phosphorus after 11 hours with
determining the pH values of approval for that, As coffee dregs when added in
doses)Coffee dreg/P = 3-10) as weight average, it fulfilled proportion removal(40 - 99) %
and phosphorus re-released after 24 hours. The outcome of these experiments was to
propose the most appropriate economic solution in the case of study.
In the present work, batch electrocoagulation experiments were carried out
to evaluate the removal of polycyclic aromatic hydrocarbon (PAHs) from water
using aluminum electrodes. The effects of initial pH, current density,
electrolysis time, initi
al concentration of PAHs, electrolyte type, and electrolyte
concentration were investigated to achieve the optimal removal efficiency. The
results indicated that the electrocoagulation utilizing the aluminum, as anode
and cathode, was an efficient tool in the reduction of these contaminants. The
treatment process was found to be largely affected by the current density and
the initial composition of water. The removal rate was significantly increased
using NaCl as an electrolyte where indirect oxidation by hypochlorite forming
later during the treatment was occurred. The results demonstrated that the
technical feasibility of the electrocoagulation as a possible and reliable
technique for the treatment of PAHs contaminants in water.
This research aims to study the dimensions of honey harvesting in the poetry of Al-
Huthaliyeen who associate talking about honey harvesting by comparing the sweet taste of
honey to a woman's saliva taste. Thus , they demonstrate the pleasure of ac
hieving the
desiredgoalafter toil. In this context , we see them highlight the mixing of honey with pure
water and wine to signify the sublime life they seek to attain. In their poetry , we see them
explore the poor living conditions of the apiarist - his toil and experiencing dangers to get
honey. They explain that in his quest of honey under difficult conditions like the rugged
place , the apiarist offers an image of a poet who strives to accomplish his goal. The
dangers of getting honey are highlighted in Al- Huthaliyeenpoetry. Such dangers increase
the hardships of reaching the goal in which the prerequisites and permanence of life are
represented.
