Auschwitz and the struggle for survival in the novel "If this is a man" by Primo Levi?

U ovom radu biće razmatrana svakodnevna borba za život i način življenja u koncentracionom logoru Aušvic u delu Prima Levija "Zar je to čovek". Nastojimo sagledati uslove života u logoru, put do tog mesta, proces selekcije i borbu za opstanak, šta se dešavalo sa ljudima ukoliko se razbole. Takođe, u radu će se nalaziti scene koje su predstavljene u filmovima "Noć i magla" i "Šaulov sin". Celu knjigu prati pitanje da li život koji se proživljavao tada uopšte može da se nazove životom.In this paper, the daily struggle for life and the way of living in the Auschwitz concentration camp will be discussed in Primo Levi's work " If This Is a Man ". In Levi’s book, the main question is whether the life that was lived then can even be called a life. Our aim is to give an overview of living conditions in the camp, the transport to the camp, the selection process and the struggle for survival. Also, we shall include some scenes from the movies "Night and Fog" and "Son of Saul".Zbornik je rezultat istraživanja u okviru Studija Holokausta koje se pod pokrovitelјstvom Claims Conference (Conference on Jewish Material Claims Against Germany) izvode na Univerzitetu u Kragujevcu.The collection of papers is the result of research within Holocaust Studies, which are conducted at the University of Kragujevac under the support of the Claims Conference (Conference on Jewish Material Claims Against Germany)

Distal nerve transfers in reconstructive surgery of injuries and diseases of peripheral nerves

Povrede perifernih nerava imaju veliki socioekonomski značaj jer obično pogađaju najreproduktivniju populaciju, životne dobi između 20 i 50 godina, a dovode do značajnog smanjenja radne sposobnosti, kao i do redukcije mogućnosti učestvovanja i uživanja u svakodnevnim životnim aktivnostima...Injuries of the peripheral nerves have got great socioeconomic significance, as they usually affect most productive population, ages 20 to 50 years, lead to significant reduction in working ability, as well as to the reduction of capability for participation and enjoument in everyday life activities..

Permanent disposal of Cs ions in the form of dense pollucite ceramics having low thermal expansion coefficient

A promising method for removal of Cs ions from water and their incorporation into stable crystal structure ready for safe and permanent disposal was described. Cs-exchanged X zeolite was hot-pressed at temperature ranging from 800 to 950 °C to fabricate dense pollucite ceramics. It was found that the application of external pressure reduced the pollucite formation temperature. The effect of sintering temperature on density, phase composition and mechanical properties was investigated. The highest density of 92.5 %TD and the highest compressive strength of 79 MPa were measured in pollucite hot-pressed at 950 °C for 3 h. Heterogeneity of samples obtained at 950 °C was determined using scanning electron microscopy. The pollucite hot-pressed at 950 °C had low linear thermal expansion coefficient of ∼4.67 × 10−6 K−1 in the temperature range from 100 to 1000 °C. © 201

Compressive strength of green concretes with low cement and high filler content

It is estimated that by the end of the current decade, about 26% of clinker will be replaced by suitable alternative materials, among which limestone filler probably has the greatest potential due to its wide availability and relatively low price. Although codes allow as much as 35% of clinker to be replaced by limestone filler, the amounts used in practice are far less and average only 6-7% globally, with no growth trend over the past ten years. In order to use the great potential of fillers, it is necessary to know the key parameters that affect the properties of green concrete with low cement and high filler content in fresh and hardened state. For that purpose, a total of 18 concrete mixtures were designed, in order to analyse the effects of the percentage of cement replacement, water-cement ratio, but also the particle size of the applied filler. The results of experimental research show that at the same w/c ratio there is an increase in compressive strength with increasing percentage of cement replacement and that it is possible to make medium-strength concretes with a significantly reduced amount of cement (180 kg/m3) compared to traditional concretes. In this way, economic benefits can be achieved, but also the negative impact of the cement industry on the environment can be reduced. Unfortunately, the workability of such mixtures can be impaired to the extent that their practical application is prevented, so it is necessary to take further steps to solve this problem

Etiology and mechanisms of ulnar and median forearm nerve injuries

© 2015, Institut za Vojnomedicinske Naucne Informacije/Documentaciju. All rights reserved. Bacgraund/Aim. Most often injuries of brachial plexus and its branches disable the injured from using their arms and/or hands. The aim of this study was to investigate the etiology and mechanisms of median and ulnar forearm nerves injuries. Methods. This retrospective cohort study included 99 patients surgically treated in the Clinic of Neurosurgery, Clinical Center of Serbia, from January 1st, 2000 to December 31st, 2010. All data are obtained from the patients' histories. Results. The majority of the injured patients were male, 81 (81.8%), while only 18 (18.2%) were females, both mainly with nerve injuries of the distal forearm – 75 (75.6%). Two injury mechanisms were present, transection in 85 patients and traction and contusion in 14 of the patients. The most frequent etiological factor of nerve injuries was cutting, in 61 of the patients. Nerve injuries are often associated with other injuries. In the studied patients there were 22 vascular injuries, 33 muscle and tendon injuries and 20 bone fractures. Conclusion. The majority of those patients with peripheral nerve injuries are represented in the working age population, which is a major socioeconomic problem. In our study 66 out of 99 patients were between 17 and 40 years old, in the most productive age. The fact that the majority of patients had nerve injuries of the distal forearm and that they are operated within the first 6 months after injury, promises them good functional prognosis

Improving sustainability of structural concrete by application of limestone filler

Modern society has the moral obligation to manage energy wisely, in order to preserve the environment for future generations. The need for cement implies the extremely high use of relatively expensive energy, evident in all segments of production and application. The use of fossil fuels during cement production is the main problem for creating the greenhouse effect and climate change. Until the end of this decade, about 10% of total CO2 emissions of anthropogenic origin will be a consequence of cement production. In order to preserve the competitiveness of concrete as the most widely used building material, it is necessary to take appropriate actions to promote sustainable development. In that way, a cement replacement with a cheaper and cleaner product – filler could have a significant global contribution. The conducted analyses shown in this paper undoubtedly provide the great potential of green concretes with low cement and high filler content in structures

Application of FeAl-LDH@SiO2 for Phosphate Removal from Water

In present study FEAL-LDH@SIO2 were Used for removing phosphate from aqueous solutions. FeAl-LDH with molar ratio Fe/Al = 3/1 was synthesized by co- precipitation from aqueous solutions in the present of SIO2 PARTICLES. Silica obtained from rice husks were used as a substrate for the deposition of LDH particles. The prepared material was characterized by scanning electron microscope (FE-SEM), X-ray diffraction (XRD), N2 adsorption/desorption isotherms (BET method) and Fourier transform infrared spectroscopy (FTIR). XRD analysis showed that Fe-Al had formed LDH structure. SEM analysis revealed deposition of LDH particles on SIO2 SUBSTRATE. The adsorption characteristics for phosphate uptake of the obtained material were performed. Adsorption experiments were carried out as a function of LDHs dosage with three different mass ratios of LDH/silica = 1/1, 2/1, and 3/1 and different phosphate concentration AT INITIAL PH 4. Phosphate concentrations were determined using spectrophotometer. The results showed that the maximum sorption capacities of phosphates calculated based on Langmuir equation was 52.68 mg g-1.The book of abstract available at: [http://conf.univerzitetpim.com/wp-content/uploads/2022/06/Book-of-Abstracts_2022-1.pdf

Epidemiologija ozljeda živaca podlaktice – retrospektivna studija

The aim of this study was to investigate the mechanisms and etiologic factors of forearm nerve injuries. This retrospective survey included all patients treated surgically in Clinical Department of Neurosurgery, Clinical Center of Serbia, from January 1, 2000 to December 31, 2010. All relevant data were collected from medical records. Statistical procedures were done using the PASW 18 statistical package. Our study included 104 patients that underwent surgery after forearm nerve injury. The majority of admitted patients were male (n=84; 80.8%) and only 20 (19.2%) were female. Ulnar nerve injury predominated with 70 cases, followed by median nerve with 54 (51.9%) cases and radial nerve with only 5 cases. Transection was the dominant mechanism of injury and it occurred in 84.6% of cases. Injury by a sharp object was the most frequent etiologic factor and it occurred in 62 (59.6%) patients, while traffic accident and gunshot injuries were the least common etiologic factor of forearm nerve injury, occurring in 7 (6.7%) and 6 (5.8%) cases, respectively. Associated injuries of muscles and tendons, bones and blood vessels occurred in 20 (19.2%), 16 (15.4%) and 15 (14.4%) patients, respectively. The etiology and mechanism of peripheral nerve injury are of great importance when choosing the right course of treatment in each individual patient because timing and type of treatment are closely related to these factors.Cilj ovoga rada bio je procijeniti mehanizme i etiološke čimbenike ozljeda perifernih živaca podlaktice. Ova retrospektivna studija je obuhvatila sve bolesnike kirurški liječene u Klinici za neurokirurgiju Kliničkog centra Srbije u razdoblju od 1. siječnja 2000. do 31. prosinca 2010. godine. Svi relevantni podaci su dobiveni iz medicinske dokumentacije. Statistička obrada podataka je načinjena primjenom statističkog paketa PASW 18. U našoj studiji koja je uključivala 104 bolesnika operirana zbog povrede perifernog živca podlaktice većinu su činili muškarci (n=84; 80,8%), dok je bilo samo 20 (19,2%) žena. Najčešće ozlijeđeni živac bio je ulnarni živac u 70 slučajeva, potom medijani živac u 54 (51,9%) slučaja, dok je najrjeđe bio ozlijeđen radijalni živac i to u 5 slučajeva. Transekcija živca je bila dominantni mehanizam ozljede živca, a utvrđena je u 84,6% bolesnika. Lezija živca oštrim predmetom je bila najčešći etiološki čimbenik utvrđen kod 62 (59,6%) bolesnika, dok su prometni traumatizam i ozljeda vatrenim oružjem bili najrjeđi etiološki čimbenici ozljede perifernog živca podlaktice i javili su se u 7 (6,7%) odnosno 6 (5,8%) slučajeva. Udružene ozljede mišića i tetiva, kostiju i krvnih žila nađene su u 20 (19,2%), 16 (15,4%) odnosno 15 (14,4%) slučajeva. Etiologija i mehanizam ozljede perifernih živaca veoma su važni za odabir pravog načina liječenja kod svakog pojedinog bolesnika, jer su vrijeme i vrsta kirurške operacije usko vezani za ove čimbenike

Carbon Cryogel Magnetite Composites-Effective Adsorbents for the Phosphate and Phenol Removal from Water

Carbon cryogel (CC) was impregnated with magnetite to produce a multifunctional magnetic adsorbent capable of removing phenoles and phosphates from water. Adsorbents were prepared via co-precipitation of Fe2+ and Fe3+ ions in aqueous solution in the presence of CC. Non-treated or acid-activated CC was used. The CC: Fe3O4 ratios of 1:1 and 3:1 were applied. The addition of HCl in the synthesis process was also investigated. XRD confirmed the formation of nanocrystalline magnetite. BET analysis showed that the pre-treatment diminished the CC porous structure, reducing also specific surface area (Sp). Formation of magnetite decreases Sp and total volume of micro and meso pores, but their distribution remained unchanged. FTIR spectra revealed that magnetite was attached to the surface of the acid activated CC via C═O bond. DTA-TGA and SEM indicated that acid treatment and presence of HCl were beneficial for homogeneous nucleation and distribution of magnetite, increasing adsorption properties of composite. Batch adsorption proved that the maximum adsorption capacity for phenoles was accomplished with 3:1 ratio with non-treated CC. Samples synthesized with pre- treated CC, under 1:1 ratio, gave the best results for phosphate removal. The CC/magnetite composite was found as promising adsorbent for the simultaneous removal of both polutants.The book of abstract available at: [http://conf.univerzitetpim.com/wp-content/uploads/2022/06/Book-of-Abstracts_2022-1.pdf

Divovska kavernozna malformacija s neuobičajeno agresivnim kliničkim tijekom: prikaz slučaja

Giant cavernomas (GC) are rare lesions, with less than 50 cases reported so far. Clinical presentation usually involves epileptic seizures and less typically focal neurological deficit, due to repeated hemorrhages and GC mass effect and consequentially increased intracranial pressure. Although individual cases have been reported, due to the rarity and variable imaging appearance, GCs are usually not considered in the differential diagnosis of large hemorrhagic lesions, especially when significant mass effect is present. A 17-year-old boy presented due to severe headache, right-sided weakness, and slurred speech. Symptoms started three days before with occasional headaches, which intensified gradually. Emergency computed tomography revealed a left frontal massive heterogeneous lesion. Soon after, right-sided hemiparesis and speech impairment progressed, and the patient became drowsy with the slightly dilated left pupil. Emergency surgery was performed, and the lobed grayish lesion was entirely removed. Based on the macroscopic appearance, the surgeon assumed it was a metastasis of melanoma. Histopathologic analysis result was cavernoma. GC should be considered as an option in hemorrhagic lesions, especially in the young age population. Emergency surgery for mass lesions is not uncommon in neurosurgery; however, bleeding cavernomas are usually planned for elective surgery due to the specific approach and complications.Divovski kavernomi (DK) su rijetke lezije s manje od 50 dosad opisanih slučajeva. Uobičajena simptomatologija su epileptični napadaji, a rjeđe se manifestiraju žarišnim neurološkim deficitom koji je uzrokovan ponavljanim hemoragijama i posljedičnim povećanjem intrakranijskog tlaka. Iako su objavljeni pojedini slučajevi, zbog rijetke pojavnosti i raznovrsne radiološke prezentacije DK se obično ne razmatraju u diferencijalnoj dijagnostici velikih hemoragičnih ekspanzivnih lezija, pogotovo kada je prisutan značajan kompresivni učinak. Sedamnaestogodišnji dječak se javio liječniku zbog jake glavobolje, blaže desnostrane slabosti i nerazgovijetnog govora. Simtpomi su se javili 3 dana ranije u vidu blagih glavobolja koje su se postupno pojačavale. Hitna kompjutorizirana tomografija je pokazala masivnu hemoragičnu leziju frontalno lijevo. Nedugo zatim desnostrana slabost i nerazgovijetan govor su se pogoršali i bolesnik je postao pospan s blago proširenom lijevom zjenicom. Učinjena je hitna operacija, kružna sivkasta lezija je u cijelosti uklonjena. Na osnovi makroskopskog izgleda kirurg je pomislio da se radi o metastazi melanoma. Histopatološka analiza je pokazala da se radi o kavernomu. DK bi trebalo razmatrati kao mogućnost kod hemoragičnih lezija, pogotovo kod mlađih bolesnika. Hitna operacija kod kompresivnih lezija nije rijetkost u neurokirurgiji, međutim, krvareći kavernomi se obično planiraju za elektivnu operaciju zbog specifičnog pristupa i mogućih komplikacija
