Tubular nanofiltration of highly concentrated C.I. Acid Black 210 dye
Authors: Zahrim A. Y. , Hilal N. , Tizaoui C.
Published: January 2013

Tubular nanofiltration membrane performance to treat water for reuse was carried out by choosing C.I. Acid Black 210 dye as a model dye. It has been shown that increasing pH causes reduction in irreversible fouling factor (IFF) and the dye removal is also affected by solution pH. The total organic carbon removal for pH 4, pH 7, pH 8 and pH 10 is 97.9, 92.3, 94.5 and 94.6%, respectively. The conductivity removal for pH 4, pH 7, pH 8 and pH 10 is 85.1, 88.3, 87.8 and 90.7% respectively. The increase in the initial dye concentration causes rapid increase in fouling until 100 mg/l. Then the fouling increases gradually as it reaches a maximum IFF around 13%. This study also shows that the colour of permeate changes from colourless to light greenish/yellowish (initial concentration of 2,000 and 4,000 mg/l) as the initial dye concentration increases. The conductivity removal was also reduced as the initial dye concentration increased due to screening of the Donnan effect with the presence of salt.

Published: January 2013

Background and objectives

There are conflicting research results about the survival differences between hemodialysis and peritoneal dialysis, especially during the first 2 years of dialysis treatment. Given the challenges of conducting randomized trials, differential rates of modality switch and transplantation, and time-varying confounding in cohort data during the first years of dialysis treatment, use of novel analytical techniques in observational cohorts can help examine the peritoneal dialysis versus hemodialysis survival discrepancy.

Design, setting, participants, & measurements

This study examined a cohort of incident dialysis patients who initiated dialysis in DaVita dialysis facilities between July of 2001 and June of 2004 and were followed for 24 months. This study used the causal modeling technique of marginal structural models to examine the survival differences between peritoneal dialysis and hemodialysis over the first 24 months, accounting for modality change, differential transplantation rates, and detailed time-varying laboratory measurements.

Results

On dialysis treatment day 90, there were 23,718 incident dialysis—22,360 hemodialysis and 1,358 peritoneal dialysis—patients. Incident peritoneal dialysis patients were younger, had fewer comorbidities, and were nine and three times more likely to switch dialysis modality and receive kidney transplantation over the 2-year period, respectively, compared with hemodialysis patients. In marginal structural models analyses, peritoneal dialysis was associated with persistently greater survival independent of the known confounders, including dialysis modality switch and transplant censorship (i.e., death hazard ratio of 0.52 [95% confidence limit 0.34–0.80]).

Conclusions

Peritoneal dialysis seems to be associated with 48% lower mortality than hemodialysis over the first 2 years of dialysis therapy independent of modality switches or differential transplantation rates.

Published: January 2013

Background and objectives

Previous reports of Fabry disease screening in dialysis patients indicate that α-galactosidase A activity alone cannot specifically and reliably identify appropriate candidates for genetic testing; a marker for secondary screening is required. Elevated plasma globotriaosylsphingosine is reported to be a hallmark of classic Fabry disease. The purpose of this study was to examine the usefulness of globotriaosylsphingosine as a secondary screening target for Fabry disease.

Design, setting, participants, & measurements

This study screened 1453 patients, comprising 50% of the male dialysis patients in Niigata Prefecture between July 1, 2010 and July 31, 2011. Screening for Fabry disease was performed by measuring the plasma α-galactosidase A enzyme activity and the globotriaosylsphingosine concentration, by high-performance liquid chromatography. Genetic testing and genetic counseling were provided.

Results

A low level of plasma α-galactosidase A activity (≤4.0 nmol/h per milliliter) was observed in 47 patients (3.2%). Of these, 3 (0.2%) had detectable globotriaosylsphingosine levels. These patients all had α-galactosidase A gene mutations: one was p.Y173X and two were the nonpathogenic p.E66Q. The patient with p.Y173X started enzyme replacement therapy. Subsequent screening of his family identified the same mutation in his elder sister and her children. Genetic testing for 33 of the other 44 patients detected 7 patients with p.E66Q. Thus, the plasma lyso-Gb3 screen identified Fabry disease with high sensitivity (100%) and specificity (94.3%).

Conclusions

Plasma globotriaosylsphingosine is a promising secondary screening target that was effective for selecting candidates for genetic counseling and testing and for uncovering unrecognized Fabry disease cases.

Authors: Hristov S. , Maksimovic N. , Stankovic B. , Zujovic M. , Pantelic V. , Stanisic N. , Zlatanovic Z.
Published: January 2013

In this paper are described the most important stressors in intensive sheep
production on farms and pastures. Stressors on farms and pastures mostly
originate from adverse housing conditions, improper zootechnical procedures,
veterinary procedures (treatment, vaccinations, blood tests, surgery), animal
husbandry procedures (labeling, weaning, grouping, shearing, shortening the
tail, hoof care), unsuitable weather conditions (extreme heat and cold) and
insufficient nutrition. The paper puts out special emphasis on the
consideration of period of life in which sheep were subjected to additional
loads and susceptible to effects of these stressors, such as birth, juvenile
period, puberty, oestrus, advanced pregnancy, parturition and the puerperal
period.

Published: January 2013

Causes for cow culling in a tie stall system were investigated on a sample of
3060 cows culled in 2011, on seven large dairy farms in the Belgrade region.
The total level of culling was 34.58% of the average number of cows. The
number of cows culled decreased with lactation order (from 981 cows in the
first to 294 cows in the sixth and later lactations). The most dominant cause
for culling were diseases of the legs and hooves (28.4%), as was expected,
having in mind the tie stall system. If selection (low production) is
abstracted as the reason for culling, what stands out by importance are
metabolic diseases (15.7%) and problems of reproduction (reproductive
diseases - 8.6%, and difficult calvings and abortions 5.7%). With the
increase of duration of the lactation during which cows were culled,
reproductive diseases gained importance as the reason for culling, while the
importance of metabolic diseases and diseases of the legs and hooves in this
context decreased. When culled, on the average, cows were 5.2 years old,
having on the average spent 1112 days in production, of which 978 days in
milking. Their average milk production per day of milking was 22.00 kg, per
day of life 10.6 kg, and per day of production 19.8 kg.

Some phenotypic and genetic trends on growth traits of lambs are observed.
The research implicated lambs of two local breeds of sheep: Lipska (LP) and
Svrljig (SV). All lambs were weighed for the first time at birth (BWB), and
thereafter, regularly in two-week intervals. On the basis of the results
during weighing the body weight (BW) were adjusted to the average age: 30
(BW30), 60 (BW60) and 90 days (BW90). Results of the effect of genotype on
growth showed a significant effect on the growth traits. Sex of lambs had a
significant effect at birth and very significant effect at 30 days, but had
no significant effect on weight at 60 (BW60) and 90 (BW90) days. Birth type
had significant effect on the body weight from birth to weaning and the
highest body weights were recorded in singles. Phenotypic correlations were
positive and very highly significant between the growth traits. Genetic
correlations were significant, but not between all observed ages of lambs.
The development pattern of IGF-1 (insulin- like growth factor-1) protein expression in breast muscle of broiler chickens
Authors: Kanacki Z. , Stojanovic S. , Uscebrka G. , Zikic D.
Published: January 2013

It is proved that the protein expression of IGF-1 is detected in several
tissues including liver, brain, eye, lung, pancreas and muscle. This growth
factor exerts autocrine and paracrine effect during embryonic and postnatal
development and is involved in muscle development. The aim of this study was
to determine the level of protein expression of IGF-1 in breast muscle during
embryonic and postnatal development of broiler chickens. For the experiment
were used fertilized eggs and broiler chickens of heavy hybrid "Ross 308",
originating from parent flock at the age of 54 weeks. Samples of breast
muscle were taken from embryos during the 15th and 19th day of embryonic
development and 3rd and 21st day of postnatal development from 5 birds in
each age category. From all of the embryos and chickens the right side of the
brest muscles were individually sampled. The muscle tissue was macerated and
then homogenized in buffer with protease inhibitors. After that
immunoprecipitation, electrophoresis and transfer the Western blot analysis
were performed on all samples. For visualization of proteins the membranes
were incubated in chemiluminescent substrate. The results indicate
statistically significant increase in protein expression of IGF-1 in breast
muscle on the 19th day of embryonic development and 3rd of postnatal
development in compared to 15th day of embryonic development (p<0,05 compared
to 19th day of embryonic development and p<0,01 compared to the 3rd day of
postnatal development). After the 3rd day of postnatal development the
protein expression was at the same level until the 21st day of postnatal
development.

Published: January 2013

Carcass conformation is a very important parameter in assessing the overall
appearance and meatiness of broilers. This study evaluates the effect of
protease supplemented to reduced protein diets on production traits, dressed
carcass weight and conformation measures in fast-growing Cobb 500 and
slow-growing Master Gris broilers over a fattening period of 49 days. At
slaughter, the following measurements were taken: pre-slaughter body weight
(BW), conventionally dressed carcass weight and abdominal fat weight.
Following carcass dissection into primal cuts, absolute conformation values,
including metatarsus length (ML), keel length (KL), breast depth (BD), breast
angle (BA) and thigh girth (TG), were determined. For carcass conformation
evaluation purposes, index values of carcass conformation measures BW/ML,
BW/KL, BW/BD and BW/TG were identified. Genotype and sex had a significant
effect on dressed carcass weight and all conformation measures, whereas the
effect of different protein levels in protease-supplemented diets was
significant only in Master Gris, for metatarsus length and the following
indices: BW/ML, BW/KL and BW/TG.

Published: January 2013

In the present experiment, the presence of mycological agents in chickens
with skin lesions on foot pads was investigated, in order to improve the
health of broiler chickens. Foot-pad dermatitis (FPD) is described in the
literature as dermatitis caused by multifactor causes. The presence of
irritating chemical substances in the litter, genetic predispositions of
hybrids, immune suppressive diseases of chickens, as well as the composition
of commercial broiler diets that influence the occurrence of wet litter, are
proven factors that contribute to a more intensive incidence of foot-pad
dermatitis. Foot-pad dermatitis is a condition characterized by lesions on
metatarsal and digital ventral skin of poultry feet. It is type of contact
dermatitis which in severe cases shows slower weight gain, poor health
condition and welfare. Taking into consideration the literature data,
chickens reared in closed facilities where the bacterial and mycological
agents are present partly in the litter if not properly disinfected, but also
in the food or the chicken plumage, we wanted to investigate their presence
in the skin of foot pads. The study was focused on incidence of foot-pad
dermatitis in 500 one day old broiler chickens of Hubbard genotype, in two
feeding (standard/economical) programs for broilers available on our market.
Chopped straw was used as litter. At the end of fattening, all chickens were
examined for the presence of lesions on the skin of the feet. Total of 39
chickens were allocated to the intensity of the lesion on foot pads rated as
2 (mild) and 3 (severe). In the mycological examination of the 9 samples of
autoclaved chicken legs with lesions on the feet, we have isolated and
identified the presence of fungi /mould Aspergillus fumigatus. The
histopathology investigation, during which the tissue section from mild and
severe skin foot pads was collected and stained using Hematoxylin and eosin,
revealed the hyperkeratosis, panniculitis, ballooning degeneration and dermis
inflammation. No fungal elements were observed in the sections of pads
stained with Gomori methenamine silver. Birds are especially susceptible to
infection with Aspergillus fumigatus. That species of fungus is also
classified as allergenic factor.

Published: January 2013

In this study the mycological and mycotoxicological contamination of maize
silage samples collected from the bottom (BL), middle (ML) and top (TL) layer
in the silage trench silo was studied. Mycological testing of the silage
contamination showed the presence of five potential toxigenic fungi of the
genera, Aspergillus, Fusarium, Mucor, Penicillium and Rhizopus with their
total number ranging from 1 to 10 x 103 CFU g-1. Also, four mycotoxins were
detected as followed, aflatoxin B1 (AFB1), zearalenone (ZON), deoxynivalenol
(DON) and fumonisin B1 (FB1). Mycotoxins AFB1 and FB1 were detected as 100%
positive in all the samples tested. An average concentration of AFB1 was 2.31
?g kg-1, 2.51 ?g kg-1 and 2.81 ?g kg-1 in BL, ML and TL respectively, while
the concentration of FB1 was 1292.00 ?g kg-1, 1298.00 ?g kg-1 and 1902.00 ?g
kg-1 in BL, TL and ML respectively. Average concentration of toxin ZON in
positive samples was 15.69 ?g kg-1 in BL and 30.68 ?g kg-1 in ML, while its
presence in the samples taken from the top layer was not detected. An average
concentration of DON toxin in positive samples were in the range of 41.71 ?g
kg-1 for TL, 79.20 ?g kg-1 for ML, while it was 97.00 ?g kg-1 for BL. There
was no statistically significant correlation between moisture content and
total number of moulds and concentrations of certain mycotoxins. However,
statistically highly significant correlations between the total number of
moulds and AFB1 concentration (r = 1.0), ZON (r = 0.99) and FB1 (r = 0.91)
were established, while weak correlation was obtained in the case of DON and
total mould counts (r = 0.54).
Canonical correlation analysis of body measurements and carcass traits of cross bred rabbit population
Authors: Ogah D.M.
Published: January 2013

In this study, canonical correlation analysis was applied to estimate the
relationship between body measurements and carcass traits of 28 male cross
bred rabbits of about 12 weeks of age, reared under semi intensive system.
Four body measurements, pre-slaughter weight (PSW) , body length (BL), chest
circumference (CC), and ear length (EL) as predictor variable while dressing
percentage ( DP) , hot carcass weight (HCW) and cold carcass weight (CCW) as
criterion variables. Pre-slaughter weight and body length had significant
(P<0.001) simple correlation coefficients with the carcass traits except for
dressing percentage. The three canonical variate pairs ranged between .99 to
.42 and only the first pair was significant (P<0.001). From the analysis
pre-slaughter weight and body length can be regarded as the main factors as
live measurement traits, while dressing percentage did not have pronounced
effect on the emerged criterion variables.

Published: January 2013

The purpose of this study has been to determine the effect of storage on
grain quality of three oat cultivars selected in Serbia - Dunav, Vrbas and NS
Tara. Freshly harvested oats were stored at the temperature of 25?2?C for 12
and 20 months. There was a significant decrease in the volume mass (458.4 to
408.9 kg/m-3) and the absolute mass of grains (26.6 to 24.2%) during the
storage. The germination potential of the grains decreased over time
(96.2-94.1%). The changes in the acid degree values (3.77-3.99 ml 1(Na OH/100
g) are highly significant (p<0.01). Initially, the pH level of the fresh
samples was 6.2, and it decreased to 5.8 after 20 months. Genotypes and
volume mass have great effect on storage duration (?2=0.8130 ?2 =0.7621 and
?2=0.6780). The interaction between the studied factors did not show
statistically significant effects on the change in germination of oat grains
(p>0.05). What mostly affects an increase in the acid degree value of oat
grains is storage duration, followed by a genotype and the interaction
between these two factors. The studied oat genotypes show no significant
differences in glassiness (p>0.05).

Porcine stress syndrome (PSS) is one kind of molecular genetics defect which
will cause malignant hyperthermia syndrome in pigs. It was reported that
mutation of pig rynodine receptor (RYR1) gene is the main reason for PSS. The
aim of this study was to test the RYR1 genotype of 10 Mangalitsa pigs using a
polymerase chain reaction-restriction endonuclease fragment length
polymorphism (PCR-RFLP) technique, which is a reliable and simple method for
RYR1 gene testing. Extraction of DNA was done by using hair follicles. The
results showed that the RYR1 genotype of all the 10 porcine cases were
negative. These results suggested that Mangalitsa pig could be one of the
porcine breeds selectively bred for medical and clinically experiments.
Intercalation of urea into kaolinite for preparation of controlled release fertilizer
Authors: Mahdavi Fariba , Abdul Rashid , Khanif Yusop
Published: January 2013

In this study urea was intercalated between layers of kaolinite by dry
grinding technique to be used for preparing controlled release fertilizer.
X-ray powder diffraction (XRPD) patterns confirmed the intercalation of urea
into kaolinite by the significant expansion of the basal spacing of kaolinite
layers from 0.710 nm to 1.090 nm. Fourier transform infrared spectroscopy
(FT-IR) also confirmed the hydrogen bonding between urea and kaolinite. Based
on CHNS elemental analysis, 20% (wt.) urea was intercalated between
kaolinite layers. The urea-intercalated kaolinite was mixed with
hydroxypropyl methylcellulose (HPMC) binder and was granulated to prepare the
nitrogen-based controlled release fertilizer. To study the nitrogen release
behavior of granules, ultraviolet/visible (UV-Vis) spectroscopy was used
through the diacetyl monoxime (DAM) colorimetric method. The result of UV-Vis
spectroscopy showed that intercalation of urea into kaolinite decreased the
nitrogen release from 25.50 to 13.66 % after 24 hours and from 98.15 to
70.01% after 30 days incubation in water. According to the results, the
prepared controlled release fertilizer (CRF) behaved according to the
standard for CRFs.
Size of government and economic growth: A nonlinear analysis
Authors: Herath Shanaka
Published: January 2013

The new growth theory establishes, among other things, that government
expenditure can manipulate the economic growth of a country. This study
attempts to explain whether government expenditure increases or decreases
economic growth in the context of Sri Lanka. Results obtained employing a
productive output series and applying an analytical framework based on second
degree polynomial regression are generally consistent with previous findings:
government expenditure and economic growth are positively correlated;
excessive government expenditure is negatively correlated with economic
growth; and investment promotes growth. In a separate section, the article
examines Armey?s idea of a quadratic curve that explains the level of
government expenditure in an economy and the corresponding level of economic
growth [Armey, D. (1995). The Freedom Revolution. Washington, D.C.: Regnery
Publishing Co.]. The findings confirm the possibility of constructing the
Armey curve for Sri Lanka, and it estimates the optimal level of government
expenditure to be approximately 27%. This article adds to the literature
indicating that the Armey curve is a reality not only for developed
economies, but also for developing economies.

Life insurance in the Republic of Macedonia has a short history, if we do not
count the experience of ZOIL Makedonija before the independence of Republic
of Macedonia. The recent history of life insurance covers the last seven
years and the segment of life insurance comprises about 6% of the total
insurance market in the Republic of Macedonia. In this paper we analyse the
development of life insurance in the Republic of Macedonia in recent history,
taking the gross premiums of two of the best companies that are working in
the segment of life insurance. Besides analysing the influence of the basic
determinants of the development of life insurance (GDP, monetary stability,
social insurance, etc.) we analyse the model of time series, with the purpose
of making a model and forecasting future values of the series.
Positive and negative affect in illusion of control
Authors: Novovic Zdenka , Kovac Aleksandra , Djuric Veljko , Biro Miklos
Published: January 2013

Research regarding the illusion of control was dominated by the studies
examining the effect of depressive affect on the overestimation of control
over uncontrollable events. However, the relative contributions of high
Negative Affect (NA) and low Positive Affect (PA), as underlying dimensions
of depressive states, has remained unclear. This study researched how both PA
and NA had affected the illusion of control. Two weeks before illusion
induction, trait PA and NA of 54 first-year university students were
assessed, and just before and after illusion induction task their state forms
were estimated. The induction consisted of solving unsolvable tasks and
obtaining positive feedback for all the answers. The illusion of control was
significantly correlated with all three PA scores, and none of the NA. After
controlling for trait measures, the PA after illusion induction remained the
only significant predictor of illusion. The relation of positive affect and
illusory judgement in maintaining mental health were discussed.
The effect of emotions on risk perception: Experimental evaluation of the affective tendencies framework
Authors: Drace Sasa , Ric François
Published: January 2013

The aim of this study was to assess the role of specific emotions on risk
perception providing a more stringent experimental test of the Appraisal
Tendencies Framework (ATF). Consistent with expectations, angry and happy
participants made more optimistic risk estimates than participants who were
made sad. As hypothesized by ATF, happiness and anger also led people to
somewhat higher certainty appraisals than sadness. However, this change in
perception did not mediate the impact of emotions on risk estimates. Taken
together, our results provide the evidence for causal role of specific
emotions in risk perception and contribute to literature showing that the
effects of emotion on judgment are not solely due to the valence of the
experienced emotion. However, they also suggest that the processes underlying
emotion effects remain in need for further specifications.
Accepting test-anxiety-related thoughts increases academic performance among undergraduate students
Authors: Senay Ibrahim , Cetinkaya Mustafa , Usak Muhammet
Published: January 2013

Given that unwanted thoughts are enhanced when suppressed, we tested among
college freshmen who were about to take an academic exam if an acceptance
strategy consisting of not suppressing intrusive thoughts will improve test
performance. This strategy proved superior to students? own default
strategies as much as a modified, alternative strategy, avoiding the
antecedents of intrusive thoughts. Moreover, the combination of the two
strategies counteracted a stronger, negative effect of test anxiety on test
performance as compared with each strategy used alone. The results suggest
that not only intrusive thoughts per se but also the suppression of these
thoughts can disrupt test performance, and hint that approaching such
thoughts with acceptance may not interfere with simultaneously working toward
avoiding the antecedents of these thoughts.

Authors: Simic Natasa , Savanovic Ljubomir , Jokic Tijana
Published: January 2013

Relationship between epistemological beliefs and motivational orientation of
high school students was studied and their relationship with school majoring,
GPA and gender. To estimate epistemological beliefs and motivational
orientation Schommer?s Epistemological Questionnaire (EQ) and Work Preference
Inventory (WPI) were used. Through factor analysis of EQ 5 factors were
extracted, that differ from those Schommer singled out. Negative correlation
between naive epistemological beliefs on one side, and intrinsic (-0.327,
p<0.01) and general motivation (-0.247, p<0.01) on the other, was determined.
Students majoring in social sciences have more mature epistemological beliefs
(F=11.278, df=1, p<0.01. Boys have more mature epistemological beliefs than
girls only on factor Avoiding relating, ambiguity and dependence on authority
(F=16.899, df=1, p<0.01). Correlation between epistemological beliefs and GPA
was not determined. Students majoring in social sciences have higher level of
motivation (F=6.626, df=1, p<0.05). Girls are more motivated by enjoying in
what they are doing (F=6.261, df=1, p<0.05).
Information value of multiple response questions
Authors: Verbic Srdjan
Published: January 2013

Answers to Multiple Response (MR) questions carry more information than we
usually utilize. Simple idea that all options of MR questions should be
scored as independent test items has two major difficulties: 1) false options
have item-response characteristics that are hard to model and use with other
items; and 2) responses to individual options within the same MR question
could be too dependent on each other. These difficulties lead to an
overestimation of item discrimination and test information function. A few
scoring methods that could increase information value obtained from MR
questions are proposed and evaluated in this paper.
Grave and power: A thanato-sociological analysis of the funerals of Tito, F. Tudjman and S. Milosevic
Authors: Kuljic Todor
Published: January 2013

The paper offers a thanato-sociological analysis of the funerals of Tito, F.
Tudjman and S. Milosevic, documenting various ideological contents and various
political roles of the funerals of heads of state. Tito?s charisma was
class-based, supranational and Yugoslav, while the other two were national
authorities. Tito?s funeral was a symbol of peace, Tudjman?s of national
liberation, and Milosevic?s a symbol resistance to imperialism. In the paper
group symbols at the funerals are analyzed, along with the content of
laudatio funebris, dimensions of authority of the deceased, key rhetorical
figures, the structure of the funeral accompaniment and the appearance of the
grave.
Sentenced “For ideological and political reasons”? The rehabilitation of Dragoljub “Draza” Mihailovic in Serbia
Authors: Dulic Tomislav
Published: January 2013

The author analyses the current process pertaining to the legal
rehabilitation of Dragoljub ?Draza? Mihailovic, the leader of the Yugoslav
Army in the Fatherland, by first placing the process in relation to
European-wide trends of coming to terms with the past. He then moves to a
discussion of the Serbian law on rehabilitation, where he points to a number
of contradictions and inconsistencies, particularly with regard to the issue
of whether war criminals can be rehabilitated. The author then turns to a
historical analysis of Mihailovic?s wartime activities, with particular
emphasis on the issues of treason and war crimes. It is the author?s main
argument that Mihailovic became embroiled in various forms of collusion with
the enemy, although these varied considerably over time. More importantly,
however, Mihailovic violated a number of legal principles of international
humanitarian law, which means that he would have been sentenced today by any
court applying the highest international standards of due process. While this
would make him ineligible for rehabilitation according to recent political
statements and the law of 2011, complications might arise due to the fact
that Mihailovic?s case will be heard in accordance with a previous law from
2006.
Ageing in the Danube gorges population (9500-5500 BC): Tooth cementum annulation method
Authors: Radovic Marija
Published: January 2013

Tooth cementum annulation, the microscopic method for the determination of an
individual?s age, gives results that are highly correlated with the
chronological age of an individual. Nevertheless, this method is still rarely
used for age estimation in archaeological populations. In this study, using
the tooth cementum annulation method, teeth of 21 individuals of the Djerdap
anthropological series, dated to a period from the 10th to the 6th millennium
BC, were analysed. The obtained data are important for overcoming some
methodological issues in anthropology of the Danube Gorges, as well as with
the precise age estimation of old individuals and with the assessment of age
in cases where the skeletal material has been very poorly preserved. The only
obstacle to the full application of the tooth cementum annulation method is
the taphonomy changes of tooth cementum which were detected on several teeth
in this study.

Some observations on lead figurines of the goddess Venus in the area between Sirmium and Viminacium
Authors: Pop-Lazic Stefan
Published: January 2013

This paper deals with the occurrence of lead figurines of the goddess Venus
in the area between the two cities of Sirmium and Viminacium. A
classification into five types, based on stylistic and iconographic features,
has been proposed. Although these types show features in common with products
of other workshops in the Danubian basin, it has been observed that such
products were not exchanged among the centres in the area. This paper puts
forward the hypothesis that there were two centres of worship of the goddess
Venus, in Sirmium and Viminacium, where these figurines could have been
manufactured.
The new epigraphic monument of Otilovici near Pljevlja
Authors: Cvijetic Jelena
Published: January 2013

The remains of an early Christian church were discovered, by chance, during
the leveling of the terrain in Otilovici near Pljevlja where there were two
monuments, or pyramidal cipi. At the same time, the older Roman necropolis
was totally destroyed, so that only the bottoms of tomb holes filled with
soot could be seen in the terrain. Following the protected archaeological
excavation, the aforementioned church and a small arched tomb by its northern
wall were uncovered in full. Another Roman tombstone was found on this
occasion, a stela which was used as a stairway from pronaos to naos in the
church. The stela belongs to a very large group of tombstones from this part
of the province and its compositional schema is a unique example in the area
of Pljevlja. From the epigraph we collected the names of four deceased
persons (Pletor, Maximina, Victorinus and Statia Fuscina). The name Pletor,
which was seen for the first time in the area of Pljevlja on this epigraph,
can be added to a large group of Illyrian names that were acknowledged in
Municipium S. The name of the deceased female Fuscina, whose nomen was
Statia, and whose names appeared on more than one epigraph in Komini and
Kolovrat, represents inhabitants who probably came from the coastal region of
Risinium. Their migration from the coast to Municipium S. could have taken
place at the end of the second or the beginning of the 3rd century when many
respectable families, due to economic crises, looked for shelter inside the
province which was wealthy with natural resources, especially ore. In fact,
this was a time of rapid growth and economic prosperity for Municipium S. The
necropolis at Otilovici points to the existence of a villa rustica or an
estate which developed into an important communications link between the
estates in Komini and Kolovrat, and which was acknowledged at the end of the
19th century by mileposts from Otilovici and Cicija.
The Haban pottery from the Belgrade fortress: Archaeological contexts, chronology, decorative designs
Authors: Bikic Vesna
Published: January 2013

Haban pottery, named after its makers, members of the Anabaptist reform
movement, flourished in Central-European countries from the end of the 16th
until the 19th century. It is tin-glazed earthenware marked by distinctive
decorative expression dominated by floral patterns. Archaeological
excavations within the area of the Belgrade Fortress have recovered some
eighty pieces of Haban pottery from well-defined and precisely dated
contexts. The pottery occurred in two separate phases of Austrian rule over
Belgrade. The earlier lasted for only two years, 1688-90, while the later
began with the Austrian capture of the city in 1717 and lasted for over two
decades, until 1739. These finds make it possible to establish the chronology
and repertoire of Haban pottery in Belgrade, contributing to our better
knowledge of this distinctive category of earthenware.
Three views on epistemological status of geometry
Authors: Jovanovic Radmila
Published: January 2013

The subject of this paper is the epistemological status of geometry. This
problem appeared in the beginning of XIX century, after the birth of
non-euclidean geometries. This scientific discovery had a big influence on
philosophy of science. We will deal with different systems of geometry,
interpreted by means of physics. We will discuss several positions regarding
their epistemological status. The key question is about the nature of
geometry as a science- is there one real geometry of our world and which one?
Both euclidean and non-euclidean geometries can be seen as to be in
accordance with our experience by introduction of a different lows of physics
but the question is if the couple P + G (physics + geometry) can be
empirically tested. We will expose three different positions about these
problems : Kant's apriorism, empiricism and conventionalism.

Plato’s Protagoras myth on origin and genesis of humans
Authors: Deretic Irina
Published: January 2013

The main claim of the paper is that, according to Plato's Protagoras myth,
humana are multidimensional beings with various dispositions, which have been
gradually developed through time. In my opinion, after the creation of
humankind had been finished, some human dispositions were further developed
and differentiated through time. In this myth four stages are described, out
of which third and fourth are to be understood as the temporal phases. I will
endeavor to show that each of them can be better accounted for by using the
different hermeneutical models, or finding out which theory underlines each
of these four stages.
On impossibility to thinking despair by all its limits
Authors: Stojanovic Milan
Published: January 2013

The purpose of this essay is a discussion on relationship between virtue and
(personal) happiness in Kant?s practical philosophy, regarding his concept of
the greatest good, and postulate of God as an attempt of conciliation of
their contradiction. And, against the Vukovic?s claim that Kant in his
transcendental philosophy conveyed attributes of God to man, it would be
highlighted Kant?s need of postulating God and returning again in the game;
against contrary A. Kozev, the concept of Transcendent, being-in-itself, will
again be interpreted as the result of Kant?s transcendental position, not as
its religious relict. The purpose of all of this is to show that when we put
the question of personal faith in the field of transcendental ethics, which
is for Kant equivalently to postulate of God (the greatest good), it comes to
sort of break through of existentialism into Kant?s transcendental
philosophy.

Causes of eye removal: Analysis of 586 eyes
Authors: Knezevic Miroslav , Paovic Jelena , Paovic Predrag , Sredojevic Vojislav
Published: January 2013

Background/Aim. Eye enucleation is one of the oldest surgical procedures. The
aim of the study was to determine the causes of enucleation as seen in a
major reference eye center in Serbia. Methods. Retrospective case series
involving a review of all enucleation procedures performed in the period
between January 2000 and December 2008 at the Institute for Eye Diseases,
Clinical Center of Serbia, Belgrade. The collected information included the
basic demographic data and diagnosis of the affected eye. The diagnosis was
made based on history, clinical and histological examinations. Clinical
indications for enucleation were categorized as tumors, glaucoma, trauma,
infections and other diseases. A statistical analysis was made using the
Student's t-test. Results. There were 586 patients, 315 male and 271 female
in our series. The mean age was 57.81, ranging from 3 months to 96 years. The
most common cause of enucleations was tumor (76.11%), (p < 0.05). Choroid
melanoma was the most common etiology leading to enucleation (81.18%),
followed by retinoblastoma (12.34%). A total of 8.02% of enucleations were
performed due to glaucoma that was primarily neovascular in 42.55% of cases
or caused by trauma in 38.8% of cases. Trauma was the third common etiology
of enucleation, and it was acute in 56.26% of cases or resulted in phthisis
bulbi in 31.25% of cases. Enucleation caused by inflammation was performed in
2.90% of cases, out of which 52.94% of enucleations occurred after
perforation of the cornea. In the group of other diseases the most common
cause of enucleation was atrophy of the eye ball. Conclusion. Neoplasm,
neovascular glaucoma, acute eye injury and atrophy of the eye ball are the
most common causes of enucleation.

Published: January 2013

Background. Renal onkocytoma is a distinctive benign tumor derived from
epithelial cells of the distal renal tubules. These tumors are often
clinically asymptomatic, diagnosed accidentally and difficult to distinguish
from renal cell carcinoma. Case report. We presented a giant renal onkocytoma
in a man aged 64, without any signs or symptoms of the urogenital system
disorder. The preoperative diagnosis described the tumor mass of the right
kidney, size 16 x 14 cm, and indicated a malignant tumor of kidney. The
patient underwent radical nephrectomy. The tumor was encapsulated at the
intersection with the characteristic central hyaline scar. Microscopically,
it was built of uniform polygonal cells with abundant eosinophilic cytoplasm.
Immunohystochemiclly, tumor cells were immunoreactive to CK AE1/AE3 and CD
117, but showed negative immunoreactivity to CK 7, RCC marker and Vimentin.
Conclusion. Giant renal oncocytomas are rare tumors with benign clinical
course. As a rule, they are discovered by accident. Clinical differentiation
from malignant tumors of the kidney is not possible. They are treated
surgically, mainly by radical nephrectomy. A definitive diagnosis is made
only by histopathological examination of tumors using immunohistochemical
marker panels.
Biter theorem
Authors: Parsev Petrovic
Published: January 2013

The article discusses the problem of investment attraction of Russian economy
in the period of transition to the market conditions of economy. The author
emphasizes that the attraction is hard to achieve because of natural
conditions (primarily climatic) and that this should not be connected with
political and other factors because this is an economic problem. After
indicating that competition cannot be directly connected with the quality of
goods, the author stresses the key hypothesis which states that in the
conditions of the free world market the level of production cost of almost
every Russian company is higher than average, which is why it is not
attractive for investments. He terms this claim the ?bitter theorem? and
proves is through the acts of natural, primarily climatic factors.
Is the eurozone rescue strategy tantamount to the rearangement of deckchairs on the Titanic?
Authors: Jovanovic Miroslav , Ljumovic Isidora
Published: January 2013

The Eurozone is the crown jewel in the process of European integration. Since
this monetary integration is a predominantly political process, it neglected
certain economic fundamentals for the long term durability (federal-type
intra-group transfer of funds). The internal troubles of the Eurozone (lack
of respect of rules) were amplified by the global credit crunch. There are
worries about the promises given to the citizens about the stability of the
Eurozone and economic progress when the zone was introduced. So much
political and economic capital has been invested in the Eurozone that its
demise is unconceivable for the time being. If the participants believe that
it is a beneficial deal it will continue its existence, but several
federal-type amendments are necessary. Otherwise, it may join a series of
monetary zones in Europe that disintegrated. Even though the Eurozone burdens
some of its member countries with high costs, the break-up of or from the
Eurozone would be even worse.
Xerophilic moulds isolated from spices used in meat industry as potential producers of mycotoxins
Authors: Skrinjar Marija , Veskovic-Moracanin Slavica , Jankovic Vesna , Vukojevic Jelena
Published: January 2013

Spices are often considered as one of the possible sources of meat products
contamination with toxigenic moulds. Genera Aspergillus, Eurotium and
Penicillium are most frequent xerophilic storage moulds that contaminate
spices. Because spices are possible source of contamination of the final
product and potential producers of mycotoxins, it is necessary to estimate
the degree of moulds contamination and their ability to produce secondary
metabolites - mycotoxins. Mycological analysis was carried out on five
samples of oregano and clove respectively. Presence of moulds was determined
by parallel usage of Sabouraud maltose agar (SMA) and the medium that
stimulates the growth of xerophilic species: malt - yeast extract agar with
50% of glucose (MY50G). Isolated moulds were classified into five genera
(Aspergillus, Alternaria, Cladosporium, Rhizopus and Penicillium) and 9
species. Mycotoxins determination was carried out using ELISA test
(commercial kits Tecna, Italy) for the presence of aflatoxin B1, ochratoxin,
A and zearalenone. The results showed the presence of aflatoxin B1,
ochratoxin A, and zearalenone in almost all samples, except one sample of
oregano and one clove sample. We can conclude that it is necessary to
introduce mandatory mycotoxins determination (aflatoxin B1, ochratoxin A), in
raw material for meat industry, especially spices. These secondary
metabolites are known as extremely toxic and are classified in group I of
human carcinogens.
