Authors: Yang Peng , Yang Jun Xiao , Chang Guan Jun
Published: February 2018

N-substituted crosslinking polybenzimidazole pyridine sulfone, as novel high performance functional polymers, was prepared by the coordination of N-substituted polybenzimidazole pyridine sulfone (Py-N-PBIS) ligand with varying content of metallic ion (Co2+, Ni2+, Zn2+). The structures of the polymers were characterized by means of FT-IR and 1H NMR spectroscopy, and the results showed a good agreement with the proposed structures. TGA measurements exhibited that the crosslinking polymers possessed good thermal stability with high thermal decomposition temperatures (thermally stable up to 405-510 °C). Additionally, the thermal stability of the coordination polymers was improved constantly with the increasing of the content of Co2+, Ni2+ or Zn2+. The metal coordination crosslinking N-substituted polybenzimidazole pyridine sulfone could be considered as a novel high performance thermoset.
Investigation on the Dealloying Process of Mn75-xNi25Alx (x=0, 5, 10, 15, 20 at. %) Alloy Ribbons
Authors: Chi Hao Yi , Bai Yan Wen , Wang Lu Yao , Zuo Min
Published: February 2018

The main purpose of this study is to investigate the impact of alloy composition and different dealloying condition on the microstructure of the nanoporous Ni. In this paper, Mn75-xNi25Alx(x=0, 5, 10, 15, 20 at. %) alloy ribbons were prepared by single roller rotary quenching system and then further investigated by X-ray Diffraction (XRD). Corrosion resistance was evaluated by means of Tafel polarization. The nanoporous nickel was synthesized by selective dissolution of Mn and Al, which is known as dealloying. The corrosion parameters of dealloying process have been studied in detail. The alloy ribbon developed into amorphous when the Al content reached 15 at.%. According to the Icorr, the corrosion resistance of Mn-Ni-Al alloy ribbons increases with the addition of Al. The addition of Al element, especially when Al content is over 15 at. %, will hinder the dealloying process resulting in the destruction of the nanoporous structure. The dealloying time is also critical to the microstructure of nanoporous nickel obtained. It was found in this work that, during dealloying process, 90 min is insufficient for complete selective dissolution of the active component (Mn and Al). However, the overextended dealloying time of 1440 min time will cause the coarsening destruction of inner porous due to the diffusion of noble element (Ni).

Authors: Chen Zhong Yi , Ma Kun , Zhou De Guo , Liu Yan , Zhang Yan Zong
Published: February 2018

A novel membrane electrode was fabricated by coating conductive slurry (K/Graphene composites as its important component) on copper foil. The membrane electrode, as anode of lithium ion battery, exhibited excellent columbic efficiency and specific capacity of 831 mAh g-1 after 1000 cycles. The K/Graphene composites presented a multi-layer nanostructure. It provided not only more intercalation space and intercalation sites for Li+ during the Li+ intercalation/extraction, but also alleviated the agglomeration of dispersed nanocrystals, as well as decreased the electrochemical impedance. The results suggest that the membrane electrode holds great potential as an anode material for LIBs.

Authors: Zhuan Run , Yang Guang , Zhang Guang Ming , Wang Wei
Published: February 2018

The treatment and disposal of excess sludge is a great challenge. Anaerobic digestion can achieve sludge reduction and harmless. However, its application is largely limited due to the low biogas production, low organic matters removal rate, odor gas production, corrosive gas destroying equipment. Sulfur is a key element resulting in these problems. In this research, potassium ferrate and ferric chloride were added to enhance anaerobic digestion. The research investigated the effects on biogas production, H2S content, microbial diversity with the addition of potassium ferrate and ferric chloride. We found that with 2.5 mg/g TS potassium ferrate, the enhancement was the highest, the total biogas production improved 18% compared with control group and organic removal rate reached 30.66%. Considering the effect of sulfur removal, 5 mg/g TS potassium ferrate resulted in the best effect, the content of H2S gas decreased 139.4%. With 2.5 mg/g TS ferric chloride, total biogas production improved 8% comparing with the control group, the content of H2S gas decreased 46%, no remarkable effect was found on the content of nitrogen and phosphorus in slurry.

Published: February 2018

The Mn-Ni/TiO2 catalyst was prepared by co-precipitation method and investigated for the low-temperature selective catalytic reduction (SCR) of NO with NH3 in this work, and Mn-Ni/TiO2 catalysts were prepared by different precipitants respectively such as sodium hydroxide, carbamide, ammonia or hydrogen peroxide. The microstructure and performance of catalysts were investigated. The activitiesof catalysts prepared by different precipitants were studied in the temperature range 90°C-350°C. The results show that Mn-Ni/TiO2catalyst prepared by CO(NH2)2-NH3·H2O-H2O2 compound precipitant has an extraordinary performance even at the low temperature of 120°C. H2-TPR results show the peak positions shift to lower temperatures, standing for the reduction potential of MnOx species is increased compared to those of Mn/TiO2 catalysts. The interaction of Ni and Mn atoms is beneficial to an enhancement of the oxygen mobility due to CO(NH2)2-NH3·H2O-H2O2 as precipitant. It is worth noting that the low temperature peak area increased by adding hydrogen peroxide as precipitant. NH3-TPD results illustrat that for the Mn/TiO2 and Mn-Ni/TiO2 catalysts which are attributed to NH3 desorbed by weak acid sites and Brønsted acid sites.

Published: February 2018

In order to investigate the effect of lanthanum on the electrochemical properties of CoB amorphous alloy, Co-Lax-B alloys (x = 0, 0.1, 0.5, and 1) were prepared by chemical reduction method. As negative electrodes in alkaline rechargeable batteries, Co-Lax-B alloys exhibit superior electrochemical properties. For Co-La0.1-B alloy, at the discharge current density of 100 mA/g, the initial discharge capacity is 830.6 mAh/g and the discharge capacity has remained around 317.3 mAh/g even after 100 cycles. Moreover, the high-rate discharge ability (HRD) of Co-La0.1-B alloy electrode at the discharge current density of 300 mA/g, 600 mA/g, and 900 mA/g is 98.16%, 95.17%, and 91.86%, respectively. The anodic polarization (AP) and the electrochemical impedance spectra (EIS) measurements indicate that the kinetics of electrochemical performance of the alloys is remarkably improved with the addition of lanthanum.

Infrared Emissivities and Microwave Absorption Properties of Perovskite La1-xCaxMnO3 (0≤x≤0.5)
Authors: Liu Jia Wei , Wang Jian Jiang , Gao Hai Tao
Published: February 2018

La1-xCaxMnO3(0≤x≤0.5) with perovskite-type structure has been successfully prepared by sol-gel method as a microwave and infrared multi-functional material. The effects of Ca incorporation on the stucture, electrical conductivity, infrared emissivity and microwave-absorbing properties were investigated in detail by XRD, 4-point probes resistivity measurement system,IR-2 infrared-emissivity analyzer and vector network analyzer. XRD results show that the perovskite structure of LaMnO3 is hardly changed when the doping concentration (x) of Ca2+ is less than or equal to 0.5. The incorporation of Ca in LaMnO3 leads to the decrease of electrical conductivity, while the infrared emissivities are decreased. Moreover, microwave-absorbing properties in the frequency range of 2-18 GHz are sensitive to Ca content. The optimal reflection loss calculated from the measured permittivity and permeability is 42 dB at 10.5 GHz with a thickness of 2.0 mm when the doping amount of Ca2+ is 0.1. It is possible to make Ca-doped lanthanum manganites achieve compatible camouflage capability for radar and infrared wave-band.
Capture of Time-Loss Overuse Soccer Injuries in the National Collegiate Athletic Association's Injury Surveillance System, 2005–2006 Through 2007–2008
Authors: Roos Karen , Kucera Kristen L. , Golightly Yvonne , Myers Joseph B. , Rosamond Wayne , Marshall Stephen W.
Published: February 2018

Context: 

Overuse injuries are reported to account for nearly 50% of sports injuries and, due to their progressive nature and the uncertainty regarding date of onset, are difficult to define and categorize. Comparing the capture rates of overuse injuries between injury-surveillance systems and medical records can clarify completeness and determinants of how overuse injuries are represented in injury-surveillance data.

Objective: 

To estimate the capture rate of time-loss medical-attention overuse injuries in men's and women's soccer in the National Collegiate Athletic Association Injury Surveillance System (NCAA ISS) compared with medical records maintained by certified athletic trainers and assess the differences in completeness of capture and factors contributing to those differences.

Design: 

Capture-recapture study.

Setting: 

Fifteen NCAA institutions provided NCAA ISS and medical record data from men's and women's soccer programs from 2005–2006 through 2007–2008.

Patients or Other Participants: 

National Collegiate Athletic Association men's and women's soccer players.

Main Outcome Measure(s): 

Time-loss medical-attention overuse injuries were defined as injuries with an overuse mechanism of injury in the NCAA ISS or medical records. Capture rates were calculated as the proportion of total overuse injuries classified as having overuse mechanisms in the NCAA ISS and the NCAA ISS and medical records combined.

Results: 

The NCAA ISS captured 63.7% of the total estimated overuse mechanisms of injury in men's and women's soccer players. The estimated proportion of overuse injury mechanisms captured by both the NCAA ISS and medical records was 37.1%. The NCAA ISS captured more overuse injury mechanisms in men's soccer than in women's soccer (79.2% versus 45.0%, χ2 = 9.60; P = .002) athletes.

Conclusions: 

From 2005–2006 through 2007–2008, the NCAA ISS captured only two thirds of time-loss medical-attention overuse mechanisms of injury in men's and women's soccer players. Future researchers should consider supplementing injury-surveillance data with a clinical record review to capture the burden of these injuries.

Published: February 2018

This study investigated the relative contributions of individual, institutional and system factors to utilisation of Research4Life databases by scientists in the National Agricultural Research Institutes (NARIs) in Nigeria. The study adopted the descriptive survey research design of the correlational type. Simple and stratified random sampling techniques were used to select 744 (62%) research scientists from a population of 1,205 in 13 NARIs. A validated and pre-tested questionnaire was the instrument adopted for this study and it consisted of 105 questions arranged in five sections A – E with 0.99 reliability coefficient based on Cronbach alpha method. Descriptive and inferential statistics - simple percentage, mean, correlation, multiple regression and analysis of variance were used to analyse the data. Result revealed that utilisation of Research4Life databases was low and the 22 individual, institutional and system factors significantly influenced utilisation of Research4Life databases in the NARIs. Individual, institutional and system factors showed varied levels of variances to utilisation of Research4Life databases in the NARIs. Out of the 22 factors investigated, five factors made significant relative contributions towards utilisation of Research4Life databases in the NARIs. System factors made significant relative contributions of three factors (perceived ease of use, database design features, local journal content), followed by one institutional (accessibility of databases) factor and one individual factor (computer anxiety). For increased utilisation of Research4Life databases in NARIs in Nigeria, individual, institutional and system factors have to be given utmost consideration.Keywords: individual factor, institutional factor, system factors, utilisation, Research4Life databases, Agricultural scientists
Naar zinvolle evaluatiemethoden voor community-projecten
Authors: Baerveldt Chris
Published: February 2018

The paper discusses the evaluation of two community-based intervention projects that were evaluated using a methodology that appears to differ strongly from traditional quasi-experimental designs. The main reason for this deviation is that traditional designs do not match the way community projects develop over time. Moreover, these designs do not provide enough information to improve these intervention projects in the future. It is argued that traditional designs can be partially tailored, but not sufficiently to address these needs. The evaluation methods that were actually used, also have drawbacks. It is argued that both the traditional and the here described evaluation methods do not provide enough information about what communities offer to children. Moreover, they do not account sufficiently for the democratic dynamics of community-based projects. A different direction is proposed, suggesting that not projects and interventions should be evaluated, but the children’s experience of (change of the) quality of the entire network of people and organizations in their community.
Selecting a climate model subset to optimise key ensemble properties
Authors: Herger Nadja , Abramowitz Gab , Knutti Reto , Angélil Oliver , Lehmann Karsten , Sanderson Benjamin M.
Published: February 2018

Abstract. End users studying impacts and risks caused by human-induced climate change
are often presented with large multi-model ensembles of climate projections
whose composition and size are arbitrarily determined. An efficient and
versatile method that finds a subset which maintains certain key properties
from the full ensemble is needed, but very little work has been done in this
area. Therefore, users typically make their own somewhat subjective subset
choices and commonly use the equally weighted model mean as a best estimate.
However, different climate model simulations cannot necessarily be regarded
as independent estimates due to the presence of duplicated code and shared
development history. Here, we present an efficient and flexible tool that makes better use of the
ensemble as a whole by finding a subset with improved mean performance
compared to the multi-model mean while at the same time maintaining the
spread and addressing the problem of model interdependence. Out-of-sample
skill and reliability are demonstrated using model-as-truth experiments. This
approach is illustrated with one set of optimisation criteria but we also
highlight the flexibility of cost functions, depending on the focus of
different users. The technique is useful for a range of applications that,
for example, minimise present-day bias to obtain an accurate ensemble mean,
reduce dependence in ensemble spread, maximise future spread, ensure good
performance of individual models in an ensemble, reduce the ensemble size
while maintaining important ensemble characteristics, or optimise several of
these at the same time. As in any calibration exercise, the final ensemble is
sensitive to the metric, observational product, and pre-processing steps used.
Extreme fluctuations of wind speed for a coastal/offshore climate: statistics and impact on wind turbine loads
Authors: Hannesdóttir Ásta , Kelly Mark , Dimitrov Nikolay
Published: February 2018

Abstract. For measurements taken over a decade at the coastal Danish site Høvsøre, we find the variance associated with wind speed events from the offshore direction to exceed the prescribed extreme turbulence model of the IEC 61400-1 Ed.3 standard for wind turbine safety. The variance of wind velocity fluctuations manifested during these events is not due to extreme turbulence; rather, it is primarily caused by ramp-like increases in wind speed associated with larger-scale meteorological processes. The measurements are both linearly detrended and high-pass filtered in order to investigate how these events – and such commonly-used filtering – affect the estimated 50-year return period of turbulence levels. The impact of the observed events on a wind turbine are investigated using aeroelastic simulations, that are driven by constrained turbulence simulation fields. Relevant wind turbine component loads from the simulations are compared with the extreme turbulence load case prescribed by the IEC standard. The loads from the event simulations are generally lower for all considered load components, with one exception: ramp-like events where the wind speed rises to exceed rated wind speed can lead to extreme tower base fore-aft loads that exceed DLC 1.3 of the IEC standard.

Authors: Sospeter Nyamagere G. , Nchimbi Mariam I.
Published: February 2018

This paper presents findings of the study that aimed at assessing the impact of business service providers (BDS) on growth of women owned MSMEs in Tanzania. Based on interviews conducted to five BDS providers and women owned micro and small enterprises (MSMEs) it was revealed that most women entrepreneurs were not aware of the existence of BDS providers and their services. For those who had used BDS, they were generally satisfied with their benefits and they continue using the services. Furthermore, the findings show that BDS assisted entrepreneurs in formalizing their businesses, increased business management and technology capacity, market coverage and contributed to business growth.Findings calls for the government, BDS providers and other key stakeholders to raise the level of awareness to women entrepreneurs on the availability and importance of using of BDSs. Government and donor community should advocate for business environment reforms that lowers the barriers to BDS providers for them to operate effectively and provide affordable services. BDS providers should focus on demand driven services in a more holistic and participatory way than they are currently doing in order to improve the quality, sustainability and development of the women owned MSMEs.

Authors: Du Chenguang , DeGuisto Kara , Albright Jordan , Alrehaili Sara
Published: February 2018

Bullying has been one of the most common forms of school violence in the world. Being the victim of bullying has been shown by many studies to suffer from serious mental and physical issues. In the current study, the relationship among the victimization, peer support, and depression symptoms was assessed, using the published data from the 2009–2010 Health Behavior in School-Aged Children Survey (N = 12,642) collected from 314 publics, Catholic, and other private schools in the United States and enrolled in students from grades 5, 6, 7, 8, 9, and 10 or their equivalent in the 50 states and the District of Columbia. The results indicated: (1) The bullied victim is positively associated with the depression symptoms, with higher victimization reporting to have higher depression symptoms. (2) The bullied victim is negatively associated with peer support, with higher victimization reporting to have lower peer support. (3) The peer support was negatively related to depression symptoms. (4) The peer support partially mediates the relationship between the victimization and depression symptoms among bullied students. This empirical study underscores the important role of peer support in mitigating the negative effect of bullying on the victim’s depression symptoms. The current results also have meaningful implication to the bullying intervention program.

Leading principles for administrative innovation: towards a robust frame of reference

In administrative practice as well as in administrative science administrative innovation is a much desired good. In this article the author makes an attempt to describe the good, or the better, that can be pursued with administrative innovation, much sharper than has been done in the past. The result is a substantive framework for qualifying and evaluating administrative innovations. The article arises from a special interaction research, that started with a question from administrative practice (about the leading principles for administrative innovation in the Dutch municipality of Breda) and ended in a confrontation between desiderata from administrative practice on the one hand and foundations from administrative science on the other hand. Finally, these six leading principles emerged out of the investigation: responsiveness, productivity, involvement, counter-pressure, creativity, and good governance. The author also discusses how the resulting framework can be used and understood. The framework is robust because it not only is theoretically (the literature on governance and democratic innovation) inspired and founded, but also recognizable and manageable for administrative practice.

Filosofie in de rechtszaal

Naar aanleiding van het optreden van Paul Cliteur in het Wilders II-proces rijst de vraag hoe de inzet van een rechtsgang zich verhoudt tot de eigen aard van de filosofie. Aan de ene kant vertolkt filosofie precies dat register van waarheid dat in het recht aan de orde is. Aan de andere kant is die vertolking zo oneindig open dat ze strijdt met het gesloten karakter van het recht als een proces dat conflicten moet beëindigen door gezagvolle beslissingen. Socrates’ optreden in zijn eigen proces toont aan: de slechtste dienst die de filosofie het recht kan bewijzen, is het verlengstuk te worden van het positieve recht en zich bij voorbaat beschikbaar te stellen als een vindplaats van argumenten wanneer de juridische argumenten op zijn. De slotparagraaf argumenteert dat Cliteur deze socratische les terzijde legt. Als gevolg daarvan geeft hij een geforceerde lezing van het Felter-arrest en mist hij de kern van het begrip ‘onverdraagzaamheid’.

The influence of air pollution on human reproduction
Authors: Wdowiak Artur , Wdowiak Edyta , Bojar Iwona , Bakalczuk Grzegorz
Published: February 2018

Air pollution is the main reason for global environmental hazards and human population. It is caused by different chemical compounds emitted by industry, vehicles and households. When inhaled with air, such substances get into the blood and they penetrate almost all the tissues, disturbing thus their physiology. Their detrimental effect is caused by the generation zanieczyszof
oxidative stress, which results in the peroxidation of cell membranes and disturbance of
basic cell functions. The latest worldwide research has proven the relationship between the
exposure to air pollution and an increased mortality rate due to cardiovascular and respiratory
diseases. Recently, it has been confirmed in numerous publications that air pollution also has
an adverse effect on the human reproductive potential.
It is the objective of the present article to analyze the current knowledge about the relationship
between hazardous substances present in the air and human fertility function.
Numerous research studies have shown that air pollution negatively affects men’s semen
parameters, especially the morphological structure of sperm. However, the available research
results present the inconsistent hierarchy of the impact that the individual chemical
substances have on a given sperm’s parameter. Air pollution is also responsible for the epigenetic
changes in sperm, which may result in genetic mutations of future generations. The
relationship between the exposure to air pollution and reduced female fertility, as well as the
risk of miscarriage and genetic disorders (e.g. Down syndrome), teratogenic effects (congenital
heart defects, neural tube defects, cleft palate) and the low birth weight of fetus, has been
already confirmed. The adverse impact of air pollution on the operating efficiency of an IVF
laboratory has been also proven. Thus, all of the above creates the need for further research
on that issue and organization of the existing knowledge.
Creative concepts as an idea to synthesize old and new architecture
Authors: Shipitsyna Olga , Zakharchuk Anzhela
Published: February 2018

An article discusses a necessity of combination of historical and contemporary architectural concepts in the process of selection of strategy for sustainable
urban development. Working out a dynamic balance between this two concepts provides sustainability of area development, which is required
for incorporation of new architectural objects in existing structure of a city. At that, usage of historical architectural concepts will allow to preserve
cultural identity of developed city, while usage of modern architects’ concepts would promote quick reaction on continuously changing social,
technical and ecological conditions of formation. An expressed hypothesis in the article regarding a necessity of such dynamic balance is illustrated
with interaction of historical concept of ensemble development of urban space with modern architects’ concepts based on combination of elements
of live and inanimate nature. Interaction of these concepts occurs after assessment of an ensemble potential state or potential of ensemble self-development
of a particular urban space. This helps to determine probable directions of urban space development in line with already incorporated genetic
program (peculiarities) of formation of an examined territory. Considering determined ensemble potential the following options of usage of modern
architectural concepts which are based on combination of live and inanimate nature elements are suggested: for regeneration of at one time destroyed or
degrading districts by means of inclusion of new unique buildings and complexes; for increase of importance of reorganized urban spaces at incorporation
of architectural and city developments objects as well as engineering infrastructure objects; for enrichment of city environment by employing natural
structures and materials, imitations of relief, landscape, natural texture in developed objects and complexes. Foregoing the above, combination of historical
and modern concepts discussed in the article would provide maintenance of urban spaces in the state of sustainable development.

O presente artigo analisa as contribuições do pensamento freireano para a formação humana integral na modalidade da Educação de Jovens e Adultos (EJA). Com essa finalidade investigativa, o estudo tem caráter bibliográfico, refletindo as ideias de Paulo Freire, sobre a formação humana integral nas obras Educação como Prática da Liberdade, Pedagogia do Oprimido e Pedagogia da Indignação. Nessa abordagem, destaca-se o sentido freireano, que entende a educação como prática de liberdade que só pode alcançar efetividade e eficácia na medida da participação livre e crítica dos educandos. A educação como prática de liberdade contrapõe-se à educação bancária cuja lógica é que a educação se torna um ato de depositar, em que os educandos são os depositários e o educador o depositante. Traz para o conceito de educação o sentimento de completude do ser humano como sujeito em constante formação, que se ressignifica a partir das experiências educacionais escolares e não escolares vivenciadas em uma dinâmica dialógica. É nessa dinâmica dialógica que Freire entende a educação de jovens e adultos como mecanismo da promoção da formação humana integral dos seus sujeitos, cujas experiências refletidas promovem mais que uma adaptação do homem ao meio, atribuindo a ele a capacidade de modificar a sua realidade. Assim, este trabalho conclui afirmando que não se pode pensar em formação na educação de jovens e adultos desarticulada das concepções freireanas de formar pessoas críticas num modelo de educação que se constitui mais eficaz quanto mais se distanciar do modelo bancário, entendendo o sujeito educando em toda a sua completude.

Despite a boxed warning, postmarketing reports of deferasirox-associated hepatic injury in patients with chronic transfusions are not well described. Hepatic impairment, including failure, has been reported to occur more frequently in patients older than 55 years and in those with significant comorbidities, including liver cirrhosis and multiorgan failure. In this case report, we describe significant hyperbilirubinemia and acute hepatocellular jaundice related to deferasirox in a 7-year-old female being treated for iron overload secondary to chronic transfusions. This report outlines a unique case without preexisting risk factors in which other causes of liver injury are excluded as defined by the Roussel Uclaf Causality Assessment Method, which indicates a probable score of deferasirox causing the injury.

Zapaljenje vimena ili mastitis kod krava je akutno ili hronično zapaljenje izvodnihkanala, parenhima ili intersticijuma jedne ili više četvrti vimena krava. Mastitisse definiše kao odgovor mlečne žlezde na prisustvo mikroorganizama. Mastitisipredstavljaju veliki zdravstveni i ekonomski problem u zapatima visokomlečnihkrava, a mogu se javiti u kliničkoj formi (klinički mastitis) sa raširenošću 1–3% i usubkliničkoj formi (subklinički mastitis) sa raširenošću više od 30%. Staphylococcusaureus izaziva teške akutne mastitise veoma često sa promenom opšteg stanja, ali isubkliničke forme mastitisa. Terapija ovog mastitisa ne daje uvek zadovoljavajućerezultate, pa je vakcinacija jedan od mogućih pristupa u rešavanju ovog problema.Stafilokoke su veoma slabi antigeni, što dodatno onemogućava i otežava pronalazakefikasne vakcine. U literaturi su opisani različiti pristupi pripreme vakcine protivmastitisa izazvanog S. aureusom. Vakcina može da sadrži inaktivisane bakterijeS. aureus, alfa i beta toksoide, proteina A i fibronectin-binding protein kao mogućeantigene u aktivaciji aktivnog imunološkog odgovora. Imunizovanje mlečne žlezdegde se kao antigen koristi inkorporisan lizat S. aureus u biodegradabilne parikule kojeimaju funkciju stimulacije produkcije i opsonizacije antitela, još je jedan od načinapripreme vakcine. Vakcina pripremljena od ekstracelularne komponente S. aureusSA2H (slime associated antigen complex SAAC) pokazala je zadovoljavajuće rezultate.Noviji pristupi pripremi vakcine ukazuju da se kao antigen može koristiti clampingfaktor A (ClfA) Staphylococcus aureusa, kao i deo membrane površinskog proteina kojise zove rTRAP (rekombinantni Target RNAIII Activating Protein) koji je sastavni deoproteina 167 AA patogenih sojeva stafilokoka. Imunoprofilaksa omogućava moderanpristup u rešavanju mastitisa izazvanih sa S. aureus, smanjenu upotrebu antibiotika uterapiji, a samim tim i smanjeno odbacivanje mleka zbog rezidua antibiotika.

Labudovi su divlje ptice vodenih staništa i pripadaju familiji Anatidae, roduAnseriformes. S obzirom na stanište, način života i ishranu, labudovi predstavljajuznačajnu bioindikatorsku vrstu za monitoring zagađivača u prirodi. Hrane seuglavnom vodenim biljkama i zelenim algama koje predstavljaju direktan pokazateljzagađenja životne sredine i vodenih staništa. Poznato je da se pasticidi kao i toksičnielementi akumuliraju i perzistiraju u vodenim ekosistemima i vodenim organizmima(alge, ribe, beskičmenjaci itd.) i preko lanca ishrane dospevaju i u kopnene biljke,životinje i čoveka. Cilj ovog rada je bio utvrđivanje stepena ugroženosti labudovakao zaštićene vrste, usled štetnog dejstva pesticida i toksičnih elemenata. Pripremauzoraka za određivanje pesticida je urađena u skladu sa multirezidualnom metodomQuEChERS. Ova metoda pripreme se zasniva na ekstrakciji sa acetonitrilom u prisustvusoli. Za kvantifikaciju rezidua pesticida korišćen je gasni hromatograf sa masenimdetektorom, Agilent Technology GCMSD 7890B/5977A sa elektronskom jonizacijomi kvadropolnim detektorom. Uzorci za merenje toksičnih elemenata pripremljeni sumetodom mikrotalasne digestije u sistemu Ethos, Microwave Labstation, Milestone,a određivanje je izvršeno tehnikom Inductively Coupled Plasma Mass Spectrometryna instrumentu Agilent ICP-MS 7700 preko izotopa: 75As, 111Cd, 201Hg, 208Pb, 56Fe, 63Cu i66Zn. Rezultati ispitivanja pesticida pokazuju da je u svim analiziranim uzorcima njihovsadržaj veoma nizak i nalazi se ispod granice kvantifikacije upotrebljene metode. Naosnovu izmerenih vrednosti toksičnih elemenata, može se zaključiti, da se njihovsadržaj kretao u intervalu, i to: za arsen 0.004 – 0.027 mg/kg; za kadmijum 0.023 –0.473 mg/kg; za živu 0.007 – 0.188 mg/kg; za olovo 0.108 – 0.248 mg/kg; za bakar 81– 810 mg/kg; za gvožđe 362 – 3288 mg/kg i za cink 21 – 127 mg/kg. Dobijeni rezultatiispitivanja ukazuju da je lokalitet prirodnog rezervata „Koviljsko-petrovaradinski rit“nezagađen pesticidima ali da treba u daljim ispitivanjima, na većem broju uzoraka,utvrditi uzroke značajno povećanog sadržaja nekih toksičnih elemenata (Cd, Hg, Cu,Fe) u ispitivanim uzorcima jetre labudova.

Пас релативно често долази у ситуацију да прогута или аспирира страно тије-ло, које може да проузрокује повреду органа или ткива и да се задржи у њима.Сви предмети чврстог агрегатног стања, а који нису храна, додатак исхрани илинека друга сварљива компонента, називају се страним тијелом. Најчешћа стра-на тијела која доспију у дигестивни систем пса су: кости, каменчићи, играчке одгуме и пластике, разне врсте лоптица, платнених и пластичних пантљика иливрпце и сл. У нашем раду описали смо и дали приједлог за лијечење проблемастраних тијела у дигестивном систему. Међутим, страна тијела могу доспјети иу дисајне путеве, спољашњи ушни канал, око, гениталне органе, интердигитал-ну, подпазушну и препонску регију. Свако од набројаних мјеста налажења стра-них тијела код паса у нашој амбуланти и пракси посебно је објашњено у раду.Из нашег искуства закључујемо да је најбитније: АСА категоризација пацијента,лоцирање страног тела и трауматизоване регије, степен оштећења ткива илиоргана, као и избор оперативне технике елиминације страног тијела. Сматрамода резултати нашег рада могу бити допринос у побољшању квалитета пружањаздравствене заштите паса, а и малих животиња уопште.

U ovom radu je opisan slučaj hronične infektivne anemije kopitara – IAK kodradnog konja na teritoriji opštine Kneževo. Sumnja na IAK je postavljena na osnovuanamneze, opšteg kliničkog pregleda, hematološkog i biohemijskih ispitivanja krvioboljele životinje. Osnovni klinički simptomi su bili: depresija, inapetenca, kaheksija,pad kondicije, blago bledilo vidljivih sluznica, tahipnoja i tahikardija. Hematološkiparametri su ukazivali na blagu anemiju: pad broja eritrocita, pad vrijednostihematokrita i hemoglobina. Biohemijskim ispitivanjem krvnog seruma utvrđena jehiperproteinemija i hipoalbuminemija. IAK je potvrđenа laboratorijskim nalazom– AGID test. Nakon konačne dijagnoze, životinja je uklonjena sa gazdinstva, što je uskladu sa važećim Pravilnikom.
