This article reports on an investigation into the ability of SiO2–Ta2O5 as a new sorbent for simultaneous preconcentration of Cd(ii), Co(ii), Cr(iii), Cu(ii), Fe(iii), Mn(ii), Ni(ii) and Pb(ii) ions from water by the column method and the parameters involved in this process.

A 78-year old man with a medical history of smoking, hyperlipidemia and hypertension was admitted to our department with ruptured abdominal aortic aneurysm (AAA) diagnosed by ultrasonography of the abdomen. The blood pressure was 60/20 mm Hg. An emergent computed tomography scan of the abdomen revealed a rupture of a giant infrarenal AAA of 16 cm in diameter with extensive intraluminal thrombus, evidence of rupture and large intraabdominal hematoma. The patient underwent a successful open surgical repair with placement of a Dacron tube graft 18 mm. The patient was transferred to the intensive care unit following successful surgical repair. Patient was transferred to the Department of cardiovascular surgery on postoperative day 2. Postoperative recovery resulted in hospital discharge at postoperative day 12.

We report a case of chronic total occlusion of the aorta with critical limb ischemia (CLI) of the lower limbs due to chronic total occlusion (CTO) of infrarenal aorta and extensive bilateral iliac disease. This case was treated by open surgical revascularization, after unsuccessful attempt of percutaneous endovascular stenting treatment. *Correspondence to: Dragan Piljic, M.D., Ph.D, Department of Cardiovascular Surgery, University Clinical Center Tuzla, Bosnia and Herzegovina, Tel: +38735303202; E-mail: dragan.piljic@dr.com Received: November 11, 2019; Accepted: November 25, 2019; Published: November 28, 2019 Case presentation A 46-year-old male, with a history of hypertension and peripheral vascular disease (including previous unsuccessful attempt endovascular stenting) was referred to our hospital for conventional open surgical treatment. The patient underwent a computed tomographic angiography, which showed complete occlusion of the infrarenal abdominal aorta, as well as both common and external iliac artery (Figure 1). He was a heavy smoker (60 cigarettes/day) and had an untreated hyperlipidemia. The operation was performed using the transperitoneal approach with limited thrombectomy through infrarenal aortotomy without transecting the aorta. The patient underwent aortic bifemoral revascularisation, with placement of a Dacron bifurcation graft of 12/6 mm. The Piljic – method was used (restricted intraoperative and postoperative fluid regime and mini-laparotomy, including surgical approach trough 8 to 10 cm paraumbilical incision. The small and large bowels were retracted to the side without being elevated out of the abdominal cavity) [1]. The patient was transfered to the intensive care unit following successful surgical repair. The patient was transfered to the department of cardiovascular surgery on the postoperative day one. Uneventful postoperative recovery resulted in hospital discharge on postoperative day four. Postoperative CTA with contrast showed a neat flow (Figure 2). Patient postoperative period has been followed up for 12 months, which ended with satisfactory general clinical and local state of both legs. Discussion In patients presenting with aortoiliac occlusive disease (AIOD), the total occlusion of the infrarenal aorta has been seen in 3 to 8.5% of cases [2]. Common causes of chronic infrarenal aortic occlusion (CIAO) include: a) atherosclerotic occlusive disease; b) middle aortic syndrome; c) Takayasu arteritis; d) fibromuscular dysplasia; e) neurofibromatosis; and f) coral reef aorta [2]. Although standardized infrarenal aortobifemoral bypass (AoBFB) remains the surgical procedure of choice for CIAO, operative decisions may proceed beyond AoBFB in complicated cases. Different therapeutic strategies include axillo-(bi) femoral bypass (AxBFB), aortoiliac endarterectomy (AIE), or hybrid procedures. AxBFB grafting usually refers to patients of high risk for aortic clamping, or patients with many comorbidities that prohibit an extensive transperitoneal procedure [3]. Surgical management Figure 1. Computed tomographic angiography showed complete occlusion of the infrarenal abdominal aorta and both common and external iliac arteries.

: The low degradability of waste materials containing lignocellulosic material is one of the factors that hinder the production of biogas. The increased need for advanced techniques in the anaerobic digestion process has led to the use of different pretreatment raw materials prior to the anaerobic digestion process in order to increase the yield of biogas. In order to maximize the yield of biogas from cattle manure in a mixture with waste sludge, the anaerobic digestion process was performed at mesophilic conditions for 54 days. As pretreatment, the thermal treatment of cattle manure at temperatures of 55 and 70 °C was applied. The highest biogas production was obtained in the sample of cattle manure, previously treated at 70 °C (M70), while the lowest was recorded in the control sample M. The specific biogas production in relation to the input quantity of volatile organic matter had the highest value in sample M70 and the lowest in the control sample. Overall results have shown that the thermal treatment of cattle manure before the anaerobic digestion process can increase both yield

Microsatellites (MS) have been, for the last two decades, widely used for parentage analysis in all types of livestock, including pigs. Conservation efforts on Banija spotted pigs included genetic characterization of the breed with MS markers. Since recent comparison of pedigree and MS data revealed some inconsistencies, the aim of this study was to develop a set of highly polymorphic and heterozygous MS markers, which could be used for parentage analysis and to prevent pedigree errors. 12 MS markers with the polymorphic information content (PIC) above 0.62 were chosen and combined into a single multiplex polymerase chain reaction (PCR). The combined non-exclusion probability for one candidate parent (NE-1P) was 0.00246149, the combined NE-1P given the genotype of a known parent of the opposite sex (NE-2P) was 0.00003739 and combined non-exclusion probability for a candidate parent pair (NE-PP) was 0.00000003. Due to a high information content of selected MS markers it was possible to obtain high accuracy in parentage assignment, which was confirmed by analyzing actual data with known genetic relationships

U ovom radu fokusirali smo se na istraživanje odnosa između koncentrisanosti bankarskog sistema Bosne i Hercegovine i Srbije, te uticaj na zaposlenost/nezaposlenosti u obe posmatrane zemlje. Osnovni zadaci i ciljevi istraživanja se odnose na determinisanje uticaja internih faktora banaka na zaposlenost/nezaposlenost, te prepoznavanje efekata unutrašnjih faktora na stopu nezaposlenosti. Kao zavisnu varijablu u ovom istraživanju koristili smo stopu nezaposlenosti, dok su kao nezavisne varijable poslužile sledeće: HHI indeks koncentracije, stopa rasta ukupne bankarske aktive, stopa rasta likvidne aktive prema ukupnoj aktivi. U cilju proučavanja kointegracije varijabli korišćena je metoda automatske regresijske raspodele, kao i metoda korelacije i regresije. Period istraživanja obuhvata period od 2008q1 do 2018q4. Rezultati istraživanja su pokazali da najsignifikantniji značaj na smanjenje nezaposlenosti mogu imati sledeće nezavisne varijable: stopa rasta ukupnih kredita, stopa rasta bankarske aktive, koncentracija kredita i depozita (posebno slučaj banaka u BiH). S druge strane, preveliki obim likvidnih sredstava prema ukupnim sredstvima iznad zakonskog minimum može uticati negativno na privredni rast i zaposlenost.

This paper discusses the situation of older people in Serbia – development and current state of art, their marginalization and ageism in the society. Stereotypes and media are in the focus, since many researches show that their impact on the adult population is huge, and they act as a ‘massive’ adult educator in the public space. An educational measure and its impact are shown in the paper, and the results of the project are presented, where several adult education organisations took part, aiming at change of the image of elderly in the society.
