In this paper the ability of three natural zeolites from different localities (Vranjska banja-VB, Igros-I and Baia Mare-BM deposits) to remove copper has been investigated. These three zeolites were subjected to the elementary analysis as well as XRDP and DTA/TG analysis due to complete characterization. Cation exchange capacity of VB, I and BM zeolites were 150.1, 169.2, and 176.5 meq/100g. The maximum adsorption capacity for the copper adsorption on VB, I and BM-zeolites were 7.75, 8.51, and 11.18 mg/g. Based on the obtained results the mathematical expression that describes correlation between the CEC and copper adsorption capacity has been developed. This linear dependance has been tested with the vast variety of experimental results. According to this expression it is possible to predict the copper adsorption capacity for different zeolites based only on their CEC value.

Rezime U slučaju austenitnih nerđajućih čelika, azot se može smatrati legirajućim elementom. Jedan od razloga je to što azot, kao intersticijski rastvoren u kristalnoj rešeci železa, doprinosi poboljšanju zateznih karakteristika, prvenstveno napona tečenja. Dodatno, zahvaljujući svom jakom austenitotvornom delovanju doprinosi povećanju stabilnosti austenita, čime je omogućena delimična supstitucija skupog i deficitarnog nikla. Legiranjem metala šava austenitnih nerđajućih čelika azotom moguće je uticati na njegove osobine. Kod postupaka zavarivanja sa gasnom zaštitom, metal šava se može legirati i putem dodavanja azota u zaštitni gas. U ovom radu su razmotreni neki od efekata dodavanja azota u argon zaštitni gas kod TIG zavarivanja austenitnog nerđajućeg čelika X5 CrNi 18 10. Abstract In the case of austenitic stainless steels, nitrogen can be considered as alloying element. One reason is that the nitrogen, interstitially dissolved in the crystal lattice of iron contributes to improved tensile properties, primarily of the yield point. In addition, thanks to its strong austenite forming action contributes to increasing the stability of austenite, thereby enabling partial substitution of expensive and scarce nickel. Alloying of the weld metal of austenitic stainless steels with nitrogen can affect its properties. In welding processes with gas protection, weld metal can also be alloyed through the addition of nitrogen in the shielding gas. This paper discusses some of the effects of the addition of nitrogen in argon shielding gas at TIG welding of austenitic stainless steel X5 CrNi 18 10.

Istražena je povezanost prevalencije i etiologije supklinickog mastitisa s pojavnoscu klinickog artritisa u 543 francuske alpske koze seroloski pozitivne na virus artritisa-encefalitisa (AEK) iz proizvodnih farmi sa sjeverozapada Hrvatske. Cilj je bio odrediti je li seroloska pozitivnost na AEK povezana s pojavnoscu supklinickog mastitisa bakterijske etiologije i istražiti je li AEK glavni uzrok pojavnosti klinickog artritisa u pretraženih koza. Sve su koze bile pregledane na pojavu klinickog artritisa. Uzorci krvi iz jugularne vene bili su testirani na AEK imunoenzimnim testom. Uzorci mlijeka, uzeti iz svake polovine vimena zasebno, pretraženi su na prisutnost bakterijskih uzrocnika mastitisa. Svi prikupljeni podatci unakrsno su klasificirani u kontingencijskim tablicama. Od ukupnog broja koza, AEK je seroloski potvrđen u 50, 8%. Supklinicki mastitis je potvrđen u 52, 3% koza. Istodobna pojava supklinickog mastitisa i AEK zabilježena je u 30% od ukupnog broja, dok je 21, 9% koza s klinickim artritisom bilo seroloski pozitivna na AEK. Statisticke su analize potvrdile pozitivnu povezanost pojave supklinickog mastitisa i AEK seropozitivnosti. Slicni su rezultati dobiveni i za povezanost pojavnosti klinickog artritisa i AEK seropozitivnosti. Također je zabilježena slaba pozitivna povezanost između supklinickog mastitisa i klinickog artritisa. Rezultati upucuju na to da bi AEK mogao utjecati na ucestalost supklinickog mastitisa. Rezultati također nalažu dodatno istraživanje AEK infekcije kao glavnog uzroka pojave klinickog artritisa u istraženim stadima.

A prospective study, which lasted from September 2014 to October 2016, covered the subjects who were examined for various benign tumor changes on the skin. The examinees were divided into 2 groups. The first group A (92 examinees) was composed of the examinees who inhabited a rural area. The second group B (98 examinees) was consisted of examinees who lived in an urban environment. The analyzed examinees gravitate towards rural and urban areas of Banja Luka, Gradiska, Stanari, Prijedor and Teslic in Bosnia and Herzegovina. The aim of this study is to analyze the attitude of examinees from rural and urban areas towards skin tumors. Parameters that were used for comparison of results are: personal attitude to skin tumors and previous skin examinations. There was no statistically significant difference in terms of prejudices among the respondents: that there is no risk of skin cancer, if a person is not exposed to the sun, and/or if changes in the skin are innate, as well as in the number of examinees who said they were not afraid of a skin tumor. In group A the number of examinees that have no opinion about skin tumors is three times higher, while in group B the number of examinees who said that they had a phobia of skin cancer is three times higher. It turned out that regular self-examination of the skin in group A is performed only by 7 (7.6%) examinees, while in group B it is done by 21 (21.5%) examinees, which proved to be statistically significantly different. Occasionally skin examination by a specialist family doctor (and/or a dermatologist) has been performed by 3 (3.3%) examinees of group A and 10 (10.3%) from group B. 4 (4.1%) examinees from group B and no one from group A perform dermoscopic examination occasionally. It was found that regular dermoscopy inspections or skin examinations by a specialist family doctor and/or dermatologist have not been done by any examinees from both analyzed groups. Attitude toward skin tumors of group A is more leisurely (less responsible), so for that group there is a possibility of higher risk degree for late diagnosis of malignant skin tumors.

Introduction: Lung cancer is often a malignant disease and one of the leading causes of death. It hes been the most common malignant disease in male population for years and has also become more frequent in fe male population. Health care and emotional support to these patients is of considerable inportance. If one of the family members is diagnosed with this disease, the family often experience problems overcomeing and understanding their own reactions in that situation. The aim of this study was to investigate to which extend the patients are informed about their disease.the awareness of patients about their disease, as well as to examine how wich family members are willing to support a sick member of their family. Methods: The study included patients suffering from lung cancer who were admitted to the Oncology Department of the University Clinical Centre in Foca for chemotherapy. After the end of the treatment patients were discharged to home health care treatment. During the home visits, patients and familiy members were interviewed. The sample consisted of N = 18 patients, and N = 18 their family members who cared for the patient at home. Patients were interviewed by means of anonymous questionnaire, and the results are displayed graphically. Results: The results showed that the respondents were quite well informed about their disease, although it sometimes happened that they did not sufficiently understand well enough given information. Half of the respondents (50% of them) were not adequately informed about the side effects of chemotherapy. Two-thirds (78%) of the family members were willing to support a sick family member, and even up to 34% of them where reluctant to seek help from health professionals. Conclusion: It is believed that knowledge and information on the character and severity of the disease significantly contribute to easier acceptance of the diagnosis and encourage the patient to active participation in their own treatment. Since the health care of lung cancer sufferers is complex , nurses should be educated enough keeping pace with technological development (diagnostics, therapy, emotional support, health education, work integration and reintegration of the patient in the corresponding group and environment).
