    A study to assess the levels of various threats and awareness among wildlife health professionals was carried out using a self administered questionnaire that focused on personal health details, the extent of exposure to various hazards, safety measures practiced and awareness level. Fifty four (46.9%) veterinarians responded to the questionnaire. The study suggests that animal related injuries (bites, wounds, scratches, fractures) were the major hazard (41%). Other health related problems and illness among professionals were backache (29.6%), hypertension (21.2%), lumbar spondylitis and anxiety (15.6% each), allergies/wheezing (11%), diabetes (10.5%), cervical spondylitis (9.4%), enteric disorders (8.9%), hypotension (5.9%), hypercholesterolemia (4.5%) and dermatitis (2.3%). Though 69% of the respondents handled hazardous chemicals during wildlife practice, none reported any mishap. Response to the presence of zoonotic diseases revealed a low level (3.7%) among the wildlife health professionals. The study revealed that despite near optimal awareness of various hazards, preventive measures are minimally practiced. It may be concluded that wildlife health professionals are exposed to a variety of hazardous situations during wildlife practice and need to remain diligent to ensure their own continued good health and that of the staff working under their supervision.Provedeno je istraživanje s ciljem procjene stupnja različitih opasnosti i osviještenosti o tim opasnostima u specijalista za zaštitu zdravlja divljih životinja. Pripremljen je upitnik s pitanjima usmjerenima na podatke o osobnom zdravlju, opsegu izloženosti različitim opasnostima, primijenjenim mjerama zaštite i stupnju osviještenosti o opasnostima. Na upitnik su odgovorila 54 (46,9%) veterinara. Istraživanje je pokazalo da je glavna opasnost (41%) ozljeda do koje dolazi u radu sa životinjama (ugrizi, rane, ogrebotine, lomovi). Drugi poremećaji zdravlja odnosili su se na bol u leđima (29,6%), povišeni krvni tlak (21,2%), lumbalni spondilitis i anksioznost (svaki po 15,6%), alergije i otežano disanje (11%), šećernu bolest (10,5%), cervikalni spondilitis (9,4%), probavne poremećaje (8,9%), sniženi krvni tlak (5,9%), povišeni kolesterol (4,5%) i upala kože (2,3%). Iako se 69% ispitanika služilo opasnim kemikalijama tijekom rada s divljim životinjama, nije bilo odgovora o nesretnim slučajevima vezanima uz to. Odgovori o potvrđenim zoonozama bili su rijetki (3,7%). Istraživanje je pokazalo da se usprkos gotovo optimalnoj osviještenosti o različitim opasnostima, preventivne mjere malo primijenjuju. Može se zaključiti da su stručnjaci koji nadziru zdravlje divljih životinja izloženi različitim opasnostima tijekom obavljanja prakse i zbog toga trebaju ustrajati u održavanju svojeg zdravlja te dobrog zdravlja osoblja koje radi pod njihovim nadzorom

    Efficiency of size-dependent particle separation by pinched flow fractionation

    Full text link
    Pinched flow fractionation is shown to be an efficient and selective way to quickly separate particles by size in a very polydisperse semi-concentrated suspension. In an effort to optimize the method, we discuss the quantitative influence of the pinching intensity in the balance between the requirements of selectivity and minimal dilution.Comment: 5 pages, 3 figures, accepted in Microfluidics and Nanofluidic

    Equilibration of Quantum hall edges in symmetry broken bilayer graphene

    Full text link
    Equilibration of quantum Hall edges is studied in a high quality dual gated bilayer graphene device in both unipolar and bipolar regime when all the degeneracies of the zero energy Landau level are completely lifted. We find that in the unipolar regime when the filling factor under the top gate region is higher than the back gate filling factor, the equilibration is partial based on their spin polarization. However, the complete mixing of the edge states is observed in the bipolar regime irrespective of their spin configurations due to the Landau level collapsing at the sharp pn junction in our thin hBN (~ 15 nm) encapsulated device, in consistent with the existing theory
