Bujar H. Abstract Trihalomethanes THMs as the main disinfection by-products DBPs during the last four decades have concerned the public and scientific opinion for the possible carcinogenic effect on human health. The purpose of this paper is to investigate the disinfection of drinking water, types of DBPs and the formation of THMs. The formation of THMs during the chlorination process represents a serious health problem, as they significantly increase the possibility of the risk of several types of cancers. In this article we are discuss the health risk imposed by THMs, considered toxic and possible carcinogenic as well as mutagenic to the human body. Thus, their elimination and regular monitoring is imperative.

Abstarct: In this paper are determinate some physicals, physical-chemical and chemical parameters of river water Shkumbini Pena to determinate the rrate level of pollution.
The parameters are measure in four samples-places in the period The parameters are measure in four samples-places in the period january-june and conclude about influence of pollution in the water Ecosystem such as about precaution stimate for his protectingly.
From results we can summarize that the river water is of first class for lot of parameters, which for moment present satisfactory ecologycal situation of the river water, that may be use for economical activity, for irrigation, for recreation and for swimming. River Water Quality. Save to Library. The region of The region of concentrations clearer solutions were found and also where the solid phase is presented is determined.
Solid phase is analyzed by means of elementary chemical analysis, IR spectroscopy and x-ray diffraction. Chemical equilibrium. This paper presents the comparative aspects of the efficiency of three different teaching approaches on the acquisition of students' knowledge and skills.
The research was carried out with students in total in the second year of The research was carried out with students in total in the second year of secondary schools from three different cities in Macedonia in relation to the topic pH and Indicators. In one of the groups Control group , the traditional teaching approach was used; in the second, simulation experiments were carried out Sim group ; and in the third group, real experiments were performed Real group.
After accomplishment of the topic, a test of knowledge was implemented. The statistical analysis of the results showed that the Real and Sim groups showed better results than the Control group. Some of the questions concerning the understanding of the processes on a molecular level were better answered in Sim groups; however, in general, it was concluded that the real experiments approach was the most effective. Chemistry Education. The purpose of this study was to investigate the effects of computer simulations and real experiments on understanding the concepts of acids and bases.
New teaching methods were focused on gaining conceptual knowledge. The investigation The investigation was performed on a sample consisted of two hundred and eleven students. The research was carried out with experimental groups and control group. In aim to measure the gained knowledge, a conceptual test of knowledge was performed, and the test results were statistically processed.
The results indicated that the students in the experimental groups, showed significantly greater achievement in comparison with the students in the control group. This shows that the implementation of computer simulations and real experiments produced better results in understanding of this concepts and removing the misconceptions.
Antithrombotic Therapy During Pregnancy more. Antithrombotic therapy is the main therapy for acute deep vein thrombosis. The objectives of anticoagulant therapy in the initial treatment are to prevent thrombus extension and early and late recurrences of deep vein thrombosis and The objectives of anticoagulant therapy in the initial treatment are to prevent thrombus extension and early and late recurrences of deep vein thrombosis and pulmonary embolism. The main objective of our study is to analyze the usage of low molecular weight heparins in women, during the period of pregnancy.
Our study, represents a retrospective study, which was undertaken during 01 July — 31 December , in the Department of Gynecology and Obstetrics, at Clinical Hospital in Tetova.
Among of pregnant women, of them received anticoagulant therapy, respectively Low Molecular Weight Heparins. Clinical Pharmacy. Water is the most essential product that is consumed by humans, which must be prevented from deterioration in quality. The quality of drinking water becomes even more important as water borne diseases spread through water.
For this For this purpose, we assess the quality of drinking water in the city of Kumanova with some physico-chemical parameters, which have a significant role in determining the potability of drinking water. In this research, parameters such as temperature, turbidity, RC, pH, EC, TRAE, TDS, COD, nitrites, nitrates, ammonia and chlorides were found to be within the permissible limits, while residual chlorine in one case were found to be below lower than the recommended limit.
We recommend that the relevant municipal authorities make regular and proper amount disinfection of drinking water, as there is no compromise that can be made when it comes to the drinking water.
Physico Chemical Analysis of Drinking Water. Fletore pune nga Kimia 7 more. In this paper are shown results of the physical-chemical and mineralogical-petrographic examinations of trepel from Brod-Gneotino, Bitola region, Republic of Macedonia. According to the scanning electronic microscopy SEM , the infra-red According to the scanning electronic microscopy SEM , the infra-red IR and powder X-ray XRPD examinations, it was determined that examined trepel is composed mainly of opal of biogenetic origin as well as quartz, illite — hydromicas, feldspars plagioclases, feldspars , and chlorites of minor importance.
With these examinations it is concluded presence of organic matter in the sample. As result of these examinations it can be concluded that this raw material trepel, natural mixture of diatomite and clay minerals can be used as raw material for production of ceramic products based on classical and hydrothermal technology , for synthesis of zeolites, as absorbent for cleaning of raw industrial waters.

It has been found that drinking water in the a The formation of carcinogenic trihalomethanes THMs in the process of water disinfection by chlorine has raised concerns in the scientific community as well as in the public opinion.
This study aims to determine the concentration of THMs The results indicate that the seasonal variation is below the critical values stipulated in the state, EU and WHO regulations seasonal average In conclusion, it can be inferred that the concentration of THMs in the drinking water of Tetova is not hazardous to human health. Environmental Engineering and Chemical Engineering. The research was carried out with The research was carried out with pupils of the second year of the gymnasium secondary schools in Macedonia.
In one of the groups, the traditional teaching method was used; in the second, there was a lecture in which virtual experiments were carried out; and in the third group, real experiments were executed. In order to verify the necessary pre-knowledge level of pupils in terms of acquiring the new lesson, there was a pre-test performed.
The results from the acquired knowledge after the accomplishment of the three teaching methods were again verified by a post-test.
