Silicon Light Emissions from Boron Implant-Induced Extended Defects
Authors: Pan G. Z. , Ostroumov R. P. , Ren L. P. , Lian Y. G. , Wang K. L. 
Published: February 2013

AbstractWe studied the electroluminescence (EL) of boron-implanted p-n junction Si LEDs in correlation with the implant-induced extended defects of different types. By varying the post implant annealing conditions to tune the extended defects and by using plan-view transmission electron microscopy to identify them, we found that {113} defects along Si<110> are the ones that result in strong silicon light emission of the p-n junction Si LEDs other than {111} perfect prismatic and {111} faulted Frank dislocation loops. The EL peak intensity at about 1.1 eV of {113} defect-engineered Si LEDs is about twenty-five times higher than that of dislocation defect-engineered Si LEDs. The EL measured at temperatures from room temperature to 4 K indicated that the emissions related to the extended defects are from silicon band edge radiative recombination.

Authors: Luijsterburg Antonius J.M. , Rozendaal Anna M. , Vermeij-Keers Christi 
Published: February 2013

Objective Using the Dutch Oral Cleft Registration, which records the morphology and topography of common oral clefts, a new classification based on the (patho)embryology of the primary and secondary palates was tested. Design Prospective observational study. Setting The fifteen cleft palate teams in the Netherlands register patients to the national registry. Patients All unoperated patients with common oral clefts reported between 1997 and 2006 inclusive were included. Main Outcome Measures The classification is based on the pathoembryological events that ultimately result in various subphenotypes of common oral clefts. Patients within the three categories cleft lip/alveolus (CL/A), cleft lip/alveolus and palate (CL/AP), and cleft palate (CP) were divided into three subgroups: fusion defects, differentiation defects, and fusion and differentiation defects. A timetable was constructed to relate the type of clefting to the time of derailment during embryonic development. Results 3512 patients were included. Patients with CL/A showed 22% fusion defects, 75% differentiation defects, and 3% fusion and differentiation defects. CL/AP patients and CP patients mostly showed fusion defects (70% and 89%, respectively). We were able to relate almost all (over 90%) cleft subphenotypes to specific weeks in embryonic development. Conclusions This classification provides new cleft subgroups that may be used for clinical and fundamental research. The subphenotypes of these subgroups originate from different time frames during embryonic development and different cell biological mechanisms, thereby enabling more accurate data for, e.g., gene identification and/or environmental factors.

An Increase in Imported Goods, Imports Have Increased – The Role of Teaching Pronunciation in an Esp Classroom
Authors: Đurović Tatjana , Silaški Nadežda 
Published: February 2013

Abstract
The fact that English has become the major lingua franca of international business and economy has influenced the goal of teaching pronunciation in an ESP economics classroom: the nativelike speaking skill as the ultimate goal has been superseded by a more realistic and more reasonable goal - the adoption of intelligibility and communicability skills. We argue here, however, that pronunciation skills should be included in a university level ESP economics course syllabus. We point out common pronunciation errors made by economics students due to first-language transfer, exemplifying our points with various types of exercises aiming at overcoming their pronunciation problems.

Published: February 2013

Abstract
Climate change, regardless of the causes shaping its rate and direction, can have far-reaching environmental, economic and social impact. A major aspect that might be transformed as a result of climate change are water resources of a catchment. The article presents a possible method of predicting water resource changes by using a meteorological data generator and classical hydrological models. The assessment of water resources in a catchment for a time horizon of 30-50 years is based on an analysis of changes in annual runoff that might occur in changing meteorological conditions. The model used for runoff analysis was the hydrological rainfall-runoff NAM model. Daily meteorological data essential for running the hydrological model were generated by means of SWGEN model. Meteorological data generated for selected climate change scenarios (GISS, CCCM and GFDL) for the years 2030 and 2050 enabled analysing different variants of climate change and their potential effects. The presented results refer to potential changes in water resources of the Kaczawa catchment. It should be emphasized that the obtained results do not say which of the climate change scenarios is more likely, but they present the consequences of climate change described by these scenarios.
Possibilities of construction of multi-functional flood pools in the mountains of Podkarpacie region, Poland
Authors: Jaremski Jan 
Published: February 2013

Abstract
The proposed concept of building storage reservoirs in mountainous Podkarpacie area will decidedly influence flood situation of this region and will decrease the extent of losses caused by the arising of landslides. A suitable geological structure allows for cheap construction of reservoirs. Dislocations and fault fissures are filled with weathering materials because of their mineralogical structure, i.e., swelling minerals cause self-sealing of the bottom. A lack of water-bearing layers eliminates uncontrolled outlet of water to the ground.

Eight species were not previously known from this area. Information on the hosts, abundance, and habitat preferences at the localities is given, and an updated map of the distribution in the Małopolska Upland is included. The taxonomic position of O. elatior s.str. and O.k ochii, diagnostic features to differentiate between them, and a revised map of distribution of both species in Poland are also presented.
Higher order reversal curves in some hysteresis models
Authors: Chwastek Krzysztof 
Published: February 2013

Abstract
Some physical concepts important for a hysteresis model (effective field, anhysteretic magnetization) are discussed on the example of Jiles-Atherton model. The Jiles-Atherton model reveals some drawbacks, which make this model more difficult to be applied in electrical engineering. In particular, it does not describe accurately the magnetization curves after a reversal, moreover complex magnetization cycles are poorly represented. On the other hand, the phenomenological description proposed by Takács seems to be a valuable alternative to the Jiles-Atherton formalism. The concept of effective field may be easily incorporated in the description.
Effect of Storage on Microbiological Quality of Honey
Authors: Różańska Hanna , Osek Jacek 
Published: February 2013

Abstract
One hundred and nine samples of honey representing different botanical types were microbiologically retested for the total number of aerobic bacteria per 1 g, the presence of anaerobic bacteria in 0.1 g, and number of yeasts and moulds per 1 g after one year of storage. The samples displayed different levels of microbiological contamination. The mean of total number of aerobic bacteria varied from 1.9 x 101 CFU/g to 4.6 x 103 CFU/g depending on the type of honey. This value, in comparison with year 2010 was lower in the case of 75 samples (68.8%), higher in 14 samples (12.8%), and stable in the remaining 20 samples (18.4%). The mean number of moulds and yeasts was 9.8 x 101 CFU/g and it was lower in 46 samples (42.2%). In 46 samples no changes were noted. The presence of anaerobic spore forming bacteria was noted in 18 samples. The presence of these microorganisms in 73 honey samples (67.0%) did not change since 2010.

Abstract
High plasma urea nitrogen concentration has been proposed as an important factor contributing to the decline in reproductive parameters of domestic animals. The aim of this study was to evaluate the effect of urea on the development of preimplantation embryos in a mouse model. During in vivo tests, acute renal failure (ARF) accompanied by hyper-uraemia was induced by intramuscular administration of glycerol (50%) into hind limbs of fertilised dams. During in vitro tests, embryos collected from healthy dams were cultured in a medium with the addition of various concentrations of urea from the 4-cell stage to the blastocyst stage. Stereomicroscopic evaluation and fluorescence staining of embryos obtained from dams with ARF showed that high blood urea is connected with an increase in the number blastocysts containing at least one apoptotic cell and in the incidences of dead cells per blastocyst, but it did not affect their ability to reach the blastocyst stage. In vitro tests showed that culture of embryos with urea at concentration of 10 mM negatively affected the quality of obtained blastocysts. Blastocysts showed significantly lower numbers of cells and increased incidence of dead cells. An increase in apoptosis incidence was observed even in blastocysts obtained from cultures with 5 mM urea. Urea at concentrations 50 mM and higher negatively affected the ability of embryos to reach the blastocyst stage and the highest used concentrations (from 500 mM) caused overall developmental arrest of embryos at the 4- or 5- cell stage. These results show that elevated levels of urea may cause changes in the microenvironment of developing preimplantation embryos, which can negatively affect their quality. Embryo growth remains un-affected up to very high concentrations of urea.

Published: February 2013

Abstract
This study describes preparation of test samples composed of freeze-dried strain of S. aureus and powdered milk as a matrix. In the first part of the study, the number of S. aureus cells freeze-dried in skim milk or horse serum were compared at two levels of contamination (104 and 105 cfu g-1). The analysis of the samples was performed three times within a week. The preliminary results showed that the samples composed of S. aureus freeze-dried in horse serum were more stable and homogeneous than those prepared with skim milk. These results were further confirmed after analysing a higher number of such samples. Therefore, this procedure was then chosen for preparation of the samples for proficiency tests (PTs). Homogeneity and stability of these samples were checked according to ISO 13528. The results obtained showed that the samples met the criteria of stability and homogeneity required for PTs and were used in PT for enumeration of S. aureus in powdered milk.

Abstract
Chronic graft-versus-host disease (GVHD) is a frequent complication after allogeneic hematopoietic stem cell transplantation (HSCT). Approximately 10% of patients with GVHD develop sclerodermatous changes, which can cause significant morbidity and are often refractory to standard systemic immunosuppression. We present two cases of sclerodermatous GVHD. The first is a 39-year-old man, who had a matched sibling, undergoing allogeneic HSCT for severe aplastic anemia. The second patient is a 7-year-old boy, who had an allogeneic HSCT from his HLA-identical mother for acute myeloid leukemia (AML). Both patients presented with widespread sclerotic changes, resulting in joint contractures and significant functional difficulties. Studies have shown UVA1 phototherapy to be a promising and well tolerated treatment modality in patients with sclerotic skin diseases. Both of our patients were treated with UVA1, which resulted in a significant skin softening, improvement in joint mobility and quality of life. UVA1 appears to be an effective treatment for refractory sclerodermatous GVHD; however, long-term clinical studies in larger groups are needed to accurately evaluate its efficacy and safety.
Treatment of acne vulgaris: a literature review / Lečenje običnih akni (acne vulgaris) – pregled literature
Authors: Subotić Milica , Đuran Verica 
Published: February 2013

Abstract
Acne vulgaris is a common skin disease, which affects individuals of all races and ages. In Caucasians, almost 85% of individuals between 12 and 25 years, as well as 25% of adults, are affected with some forms of acne. The pathophysiology of acne is multifactorial, and thus, the treatment must cover all the possible causes of acne. For this reason, acne therapy is mostly a combination therapy, with the main goal to achieve clinical improvement, without scarring and residuals, as much as possible. The treatment should be planned individually, depending on the clinical appearance, severity and psychological profile of the patient. The treatment usually takes time and requires dedication and patience of both the patient and the physician.
Bullous lichen planus in childhood – A case report / Bulozni lichen planus u dečijem uzrastu
Authors: Arsov Biljana , Popadić Svetlana , Nikolić Miloš 
Published: February 2013

Abstract
In Europe, only 1% of all patients with lichen planus are children. We report a case of lichen planus in a 5-year-old boy with blisters developing on papules. There was no history of Hepatitis B virus vaccination in the past 12 months. Routine laboratory analyses showed no abnormalities. Hepatitis B surface antigen and anti-Hepatitis C virus antibodies were negative. Our patient had disseminated and coalesced papules on the trunk and extremities with vesicles and bullae on the hands and feet. Histopathology confirmed the diagnosis of lichen planus and bullous lichen planus. Negative direct immunofluorscence test excluded lichen planus pemphigoides. The boy was treated with prednisone 1 mg/kg/ day (the dose was gradually tapered and discontinued over the next 1.5 month), ultraviolet B phototherapy, fluocinolon acetonide, and topical pimecrolimus 1% cream till complete remission after 2.5 months. Bullous form of lichen planus is seen in 1-16% of all children with lichen planus. Two months upon the completion of therapy, there were no signs of relapse. In our case, short course of systemic corticosteroids and ultraviolet B phototherapy have been safe and effective. This was the only pediatric case of bullous lichen planus treated in our Clinic in the last 20 years. Long-term prognosis of childhood lichen planus is not predictable, and there is no consensus regarding the treatment of childhood lichen planus.
History of Dermatology and Venereology in Serbia - Part I: Medieval Dermatovenereology / Istorija Dermatovenerologije U Srbiji - I Deo: Srednjovekovna Dermatovenerologija

Published: February 2013

Abstract
Medieval medicine in Serbia used to be the scientific medicine of that time. It included dermatology and venereology, which developed into an independent discipline in the second half of the 19th century. The most relevant sources for studying dermatology and venereology are Serbian medieval medical and therapeutic codices. The terms used in the manuscripts report about the diseases people in Serbia suffered from and were treated for in the Middle Ages. The following diseases were reported: scabies, leprosy, fungal scalp infections, as well as psoriasis, crusts (pyococcal ulcers), granulation, baldness, excessive body hair, leg wounds and old wounds, facial spots, unspecified skin diseases, urethritis and syphilis. Special attention was also given to cosmetics. Topical remedies were applied - various herbs, sulphur, mercury, tar, pyrethrum, plasters, ground glass, auripigment - in the form of a powder, liniment, ointment or plaster.
Th e 2nd Congress of the Pan-Slavic Association of Dermatovenereologists, belgrade 1931
Authors: Lalević-Vasić Bosiljka M. 
Published: February 2013

Abstract
The Pan-Slavic Association of Dermatovenereologists (PSADVs) was founded in May 1928, and it included dermatologic associations of Bulgaria, Czechoslovakia, Poland and Yugoslavia. Its president was Prof. Krzysztalowicz from Poland. The 1st Congress of this association was held in Warsaw in 1929, and the 2nd Congress was organized by the Association of Dermatovenereologists of Yugoslavia (ADVY), in Belgrade in 1931. The president of the Organizing Committee was Prof. Đorđe Đorđevic, and the secretary Assoc. Prof. Milan Kićevac from the Clinic of Dermatovenereology in Belgrade. The Congress was attended by representatives of Slavic national associations, as well as by representatives of French, Romanian, Greek and Turkish dermatology. The number of participants amounted to 160 physicians and 60 members of their families.
According to the report of Ilić S., 104 papers had been presented: 48 from Yugoslavia (37 from Serbia, 3 from Croatia, 3 from Macedonia, and 5 from Bosnia), 23 from Czechoslovakia, 18 from Poland, 8 from France, 5 from Romania, 1 from Turkey, and 1 from Greece.
Most papers were from the area of sexually transmitted diseases: 43 papers (41.35% of the total number). Out of these, 27 papers were on syphilis, followed by gonorrhea with 9 papers. There were both research and experimental papers. The authors insisted on assessing diagnostic and therapeutic issues, as well as disease prevention.
The second most frequent group of diseases accounted for eczema. The problem included the defi nition and pathogenesis of the disease. The third group of diseases was tuberculosis. The results of experiments on animals were studied pointing out the need for reclassifi cation of skin tuberculosis in relation to internal tuberculosis.
A small number of papers were on other infections of the skin and genitals, as well as individual cases of various dermatoses. During the Congress, social events were also organized, as well as a banquet on the ship Alexander I cruising on the Danube and Sava. Optional travel tours to all parts of Yugoslavia were also offered.
Soon after the Congress, foreign journals published reports on its high professional level and the entire organization.
Exposure-Dependent Variations in Air Temperature and Humidity on the Moraine of the Aavatsmark Glacier (Nw Spitsbergen) in the Summer Season of 2010
Authors: Araźny Andrzej , Przybylak Rajmund 
Published: February 2013

Abstract
The article presents results of research on the development of air temperature and relative humidity at a height of 5 cm above the active surface of the terminal lateral moraine of the Aavatsmark Glacier, relative to its exposure in the summer season of 2010. Variations in the two conditions were analysed for five measurement sites situated on northerly (SN), easterly (SE), southerly (SS) and westerly (SW) slopes, as well as on the flat top surface of the moraine (STop), in different weather conditions. The article also includes a temperature and humidity stratification in the near surface air layer (5-200 cm) above the moraine. The issues were investigated for mean values from the whole period of research, as well as for individual days demonstrating distinct degrees of cloudiness and wind speed.
