description: We have monitored the Cassiopeia dwarf galaxy (IC 10) in a series of 10 Chandra ACIS-S observations to capture its variable and transient X-ray source population, which is expected to be dominated by High Mass X-ray Binaries (HMXBs). We present a sample of 21 X-ray sources that are variable between observations at the 3 sigma level, from a catalog of 110 unique point sources. We find 4 transients (flux variability ratio greater than 10) and a further 8 objects with ratio > 5. The observations span years 2003 - 2010 and reach a limiting luminosity of >10$^{35}$ erg/s, providing sensitivity to X-ray binaries in IC 10 as well as flare stars in the foreground Milky Way. The nature of the variable sources is investigated from light-curves, X-ray spectra, energy quantiles, and optical counterparts. The purpose of this study is to discover the composition of the X-ray binary population in a young starburst environment. IC 10 provides a sharp contrast in stellar population age (<10 My) when compared to the Magellanic Clouds (40-200 My) where most of the known HMXBs reside. We find 10 strong HMXB candidates, 2 probable background Active Galactic Nuclei, 4 foreground flare-stars or active binaries, and 5 not yet classifiable sources. Complete classification of the sample requires optical spectroscopy for radial velocity analysis and deeper X-ray observations to obtain higher S/N spectra and search for pulsations. A catalog and supporting dataset are provided.

description: The graviton exchange effect on cosmological correlation functions is examined by employing the double-soft limit technique. A new relation among correlation functions that contain the effects due to graviton exchange diagrams in addition to those due to scalar-exchange and scalar-contact-interaction, is derived by using the background field method and independently by the method of Ward identities associated with dilatation symmetry. We compare these three terms, putting small values for the slow-roll parameters and $(1-n_{s}) = 0.042$, where $n_{s}$ is the scalar spectral index. It is argued that the graviton exchange effects are more dominant than the other two and could be observed in the trispectrum in the double-soft limit. Our observation strengthens the previous work by Seery, Sloth and Vernizzi, in which it has been argued that the graviton exchange dominates in the counter-collinear limit for single field slow-roll inflation.

description: The backside coronal mass ejection (CME) of 2012 July 23 had a short Sun to Earth shock transit time (18.5 hours). The associated solar energetic particle (SEP) event had a >10 MeV proton flux peaking at ~5000 pfu, and the energetic storm particle (ESP) event was an order of magnitude larger, making it the most intense event in the space era at these energies. By a detailed analysis of the CME, shock, and SEP characteristics, we find that the July 23 event is consistent with a high-energy SEP event (accelerating particles to GeV energies). The time of maximum and fluence spectra in the range 10-100 MeV were very hard, similar to those of ground level enhancement (GLE) events. We found a hierarchical relationship between the CME initial speeds and the fluence spectral indices: CMEs with low initial speeds had SEP events with the softest spectra, while those with highest initial speeds had SEP events with the hardest spectra. CMEs attaining intermediate speeds result in moderately hard spectra. The July 23 event was in the group of hard-spectrum events. During the July 23 event, the shock speed (>2000 km s^-1), the initial acceleration (~1.70 km s^-2), and the shock formation height (~1.5 solar radii) were all typical of GLE events. The associated type II burst had emission components from metric to kilometric wavelengths suggesting a strong shock. These observation confirm that the 2012 July 23 event is likely to be an extreme event in terms of the energetic particles it accelerated.

description: We selected approximately 10,500 Narrow Angle Camera (NAC) and Wide-Angle Camera (WAC) stereo images obtained by the MESSENGER spacecraft during its orbital mission with average resolutions of 150 m/pixel to compute a Digital Terrain Model (DTM) for the so-called H6 quadrangle (Kuiper), extending between 22.5°S to 22.5°N and 288.0°E to 360.0°E. Among the images, we identified about 21,100 stereo image combinations with each combination consisting of at least 3 images. We applied sparse multi-image matching to derive approximately 250,000 tie-points representing 50,000 ground points. We used the tie-points to carry out a photogrammetric block adjustment, which improves the image pointing and the accuracy of (3D) ground points from about 850 m to approximately 55 m. Subsequently, we applied high density (pixel-by-pixel) multi-image matching to derive about 45 billion tie-points. Benefitting from improved image pointing data, we compute about 6.3 billion surface points. By interpolation, we generated a DEM with a lateral spacing of 221.7 m/pixel (192 pixels per degree) and a vertical accuracy of about 30 m. The comparison of the DEM with the Mercury Laser Altimeter (MLA) tracks obtained over 4 years of MESSENGER operation reveals that the DEM is geometrically very rigid. It may be used as a reference to identify MLA outliers (when MLA operating at ranging limit) or to map offsets of laser altimeter tracks, presumably caused by residual spacecraft orbit and attitude errors. After the relevant outlier removal and corrections, MLA profiles show excellent agreement with topographic profiles from H6 with root mean square height difference of only 88 m.

description: Determining elemental abundances of bulge stars can, via chemical evolution modeling, help to understand the formation and evolution of the bulge. Recently there have been claims both for and against the bulge having a different [$α$/Fe] vs. [Fe/H]-trend as compared to the local thick disk possibly meaning a faster, or at least different, formation time scale of the bulge as compared to the local thick disk. We aim to determine the abundances of oxygen, magnesium, calcium, and titanium in a sample of 46 bulge K-giants, 35 of which have been analyzed for oxygen and magnesium in previous works, and compare them to homogeneously determined elemental abundances of a local disk sample of 291 K-giants. We use spectral synthesis to determine both the stellar parameters as well as the elemental abundances of the bulge stars analyzed here. The method is exactly the same as was used for analyzing the comparison sample of 291 local K-giants in Paper I of this series. Compared to the previous analysis of the 35 stars in our sample, we find lower [Mg/Fe] for [Fe/H]>-0.5, and therefore contradict the conclusion about a declining [O/Mg] for increasing [Fe/H]. We instead see a constant [O/Mg] over all the observed [Fe/H] in the bulge. Furthermore, we find no evidence for a different behavior of the alpha-iron trends in the bulge as compared to the local thick disk from our two samples.

Assessment of Relationship between Infant Death and High Risk Fertility Behavior among Married Women of Afar. Zone Four
Creators: name: Alemu, Tesfu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2006

description: Background: - Pregnancy occurring too early too close to often or too late in life is associated with high risk related to health both to mother and child. It is also noted that infant mortality differential exists with regard to at least three variables related to fertility: length of interval between successive birth, birth order, and maternal age. All the studies note that infant mortality increases with birth order, and that it is higher when the mother is at the upper or lower end of the childbearing span or when the interval between two successive births is very short. A major improvement in the health of women and children can be achieved by ensuring that pregnancies are planned to occur at the right time in the life of women. Therefore, women can bear their children under optimal conditions of number, age and spacing. Objective:-The objectives of the study is therefore to asses the prevalence of high- risk fertility and its relationship with infant death and some cultural factor affecting fertility and infant death. Method: - The study is a comparative study which is cross sectional using both quantitative and qualitative method. Result: -A total of 1299 eligible women were included in the study. Among 1299 respondents more than 96% were illiterate and full time house wives. Early marriage is a common practice with mean age and standard deviation of 15 ± 2.2. As a child's value is high, large family sizes were highly preferred by the study women. There is no known traditional contraceptive method used in the community and more than half of the respondents were unaware of the existence of modern family planning methods. VI 72 Sixty seven percent of the study women were at risk of high parity followed by close birth spacing (34.9%) and too old (28.87%). High risk of infant death were associated with short birth interval (adjusted OR 1.6 95% CI 1.1 2.5), old age (adjusted OR 1.8 95% CI 1.14 2.8) and with low birth weight adjusted (OR 3.0 95% CI 2.0 – 4.7). Conclusion and Recommendation: - This study has shows that women in the study area are illiterate, socially burdened to produce as many children as possible and highly exposed to other high risk fertility behavior and higher child loss. Although, the study population is young, bio demographic risk like higher parity, frequent birth, old age has been prevailed. Infant mortality risk was found to be highly associated with low birth weight, frequent birth, and old age. Thus, Community sensitization and sustainable IEC related to high risk fertility and early marriage; improved Integrated maternal and child health service giving special emphasis to pregnant woman and family planning is recommended. Extension of the services to the community through TBA and front line health worker; and Encouragement of women's and girl's education and improvement of provision of pure water are strongly recommended

Scalar versus fermionic top partner interpretations of $t\bar t + E_T^{\rm miss}$ searches at the LHC

description: We assess how different ATLAS and CMS searches for supersymmetry in the $t\bar t + E_T^{\rm miss}$ final state at Run 1 of the LHC constrain scenarios with a fermionic top partner and a dark matter candidate. We find that the efficiencies of these searches in all-hadronic, 1-lepton and 2-lepton channels are quite similar for scalar and fermionic top partners. Therefore, in general, efficiency maps for stop-neutralino simplified models can also be applied to fermionic top-partner models, provided the narrow width approximation holds in the latter. Owing to the much higher production cross-sections of heavy top quarks as compared to stops, masses up to $m_T\approx 850$ GeV can be excluded from the Run 1 stop searches. Since the simplified-model results published by ATLAS and CMS do not extend to such high masses, we provide our own efficiency maps obtained with CheckMATE and MadAnalysis 5 for these searches. Finally, we also discuss how generic gluino/squark searches in multi-jet final states constrain heavy top partner production.

description: We discuss heat transport in thermally-biased long Josephson tunnel junctions in the presence of an in-plane magnetic field. In full analogy with the Josephson critical current, the phase-dependent component of the heat current through the junction displays coherent diffraction. Thermal transport is analyzed as a function of both the length and the damping of the junction, highlighting deviations from the standard Fraunhofer pattern characteristic of short junctions. The heat current diffraction patterns show features strongly related to the formation and penetration of Josephson vortices, i.e. solitons. We show that a dynamical treatment of the system is crucial for the realistic description of the Josephson junction and it leads to peculiar results. In fact, hysteretic behaviors in the diffraction patterns when the field is swept up and down are observed, corresponding to the trapping of vortices in the junction.

description: We study the resonant tidal excitation of g modes in coalescing superfluid neutron star (NS) binaries and investigate how such tidal driving impacts the gravitational-wave (GW) signal of the inspiral. Previous studies of this type treated the NS core as a normal fluid and thus did not account for its expected superfluidity. The source of buoyancy that supports the g modes is fundamentally different in the two cases: in a normal fluid core the buoyancy is due to gradients in the proton-to-neutron fraction whereas in a superfluid core it is due to gradients in the muon-to-electron fraction. The latter yields a stronger stratification and a superfluid NS therefore has a denser spectrum of g modes with frequencies above 10 Hz. As a result, many more g modes undergo resonant tidal excitation as the binary sweeps through the bandwidth of GW detectors such as LIGO. We find that roughly 10 times more orbital energy is transferred into g mode oscillations if the NS has a superfluid core rather than a normal fluid core. However, because this energy is transferred later in the inspiral when the orbital decay is faster, the accumulated phase error in the gravitational waveform is comparable for a superfluid and a normal fluid NS (about 0.001-0.01 rad). A phase error of this magnitude is too small to be measured from a single event with the current generation of GW detectors.

Adherence to Antiretroviral Therapy in Currently Changed Treatment Guideline on People living with HIV/AIDS at Bishofitu Hospital, East Shoa, 2011. Ethiopa
Creators: name: W/Tsadik, Asegid
Publisher: name: National Academic Digital Repository of Ethiopia

description: Background: Adherence to antiretroviral therapy (ART) is crucial to ensure viral suppression, decrease the risk of disease progression and drug resistance. Non-adherence to ART, likewise, is common in all groups of treated individuals & lack of strict adherence to ART is considered to be one of the key challenges to AIDS care worldwide. Objective: To assess adherence to ART on currently changed guideline and factors associated with it among People Living with HIV/AIDS (PLWHA) attending ART unit at Bishofitu Hospital. Method: A cross sectional survey of 317 clients attending for ART at Bishofitu Hospital was carried out using both quantitative & qualitative design method. Using a structured and pre-tested questionnaire, data on drug adherence and other variables was collected through in-depth interview, peer educators FGD, patient's self report (interview), pill count and by reviewing their clinical records. The nurse & ART Clinician who are working in the ART unit were involved in data collection after being trained. Ethical clearance was obtained from concerned bodies and consent was sought from the study subjects. Adherence is defined as the number of doses taken divided by the number of doses prescribed over a given period. It is considered as good if the patient took ≥ 95% of the prescribed doses correctly. Odds ratio was done to determine the strength of association for different variables. Major Findings The overall prevalence of HAART adherence was found to be, 398(95.4%) in this study. The highest proportion, 61 % of patients missed or delayed their doses due to simply forgetting & 47.4% due to being away from home & 29.4% being too busy. Independent positive predictors of HAART non adherence reported in this study comprise:-the participants who had: PLWHA's residency far from Bishofitu hospital (>47 KM.), depression feelings , ART eligibility knowledge, medication adverse effect, history active substance uses, no adequate social support & one or two children under their care in the final adjusted multivariate analysis. Conclusions & Recommendations: The prevalence of ART adherence among clients using currently changed single combined fixed dose in this study was found higher than most studies done in developed countries & even much higher than the findings of other studies in Ethiopia. From these, we can infer that single & simplified ART has reduced the pill burden & helped the clients to take it at ease & this has increased the level of adherence behavior of clients, therefore continuous effort should be made to increase clients' awareness to maintain the best level of adherence outcomes

description: Mixed-signal neuromorphic systems represent a promising solution for solving extreme-edge computing tasks without relying on external computing resources. Their spiking neural network circuits are optimized for processing sensory data on-line in continuous-time. However, their low precision and high variability can severely limit their performance. To address this issue and improve their robustness to inhomogeneities and noise in both their internal state variables and external input signals, we designed on-chip learning circuits with short-term analog dynamics and long-term tristate discretization mechanisms. An additional hysteretic stop-learning mechanism is included to improve stability and automatically disable weight updates when necessary, to enable continuous always-on learning. We designed a spiking neural network with these learning circuits in a prototype chip using a 180 nm CMOS technology. Simulation and silicon measurement results from the prototype chip are presented. These circuits enable the construction of large-scale spiking neural networks with online learning capabilities for real-world edge computing tasks.

description: User Experience (UX) professionals need to be able to analyze large amounts of usage data on their own to make evidence-based design decisions. However, the design process for In-Vehicle Information Systems (IVIS) lacks data-driven support and effective tools for visualizing and analyzing user interaction data. Therefore, we propose ICEBOAT, an interactive visualization tool tailored to the needs of automotive UX experts to effectively and efficiently evaluate driver interactions with IVISs. ICEBOAT visualizes telematics data collected from production line vehicles, allowing UX experts to perform task-specific analyses. Following a mixed methods User-centered design (UCD) approach, we conducted an interview study (N=4) to extract the domain specific information and interaction needs of automotive UX experts and used a co-design approach (N=4) to develop an interactive analysis tool. Our evaluation (N=12) shows that ICEBOAT enables UX experts to efficiently generate knowledge that facilitates data-driven design decisions.

description: Quasiparticle properties of quantum magnets with long-range interactions are investigated by high-order linked-cluster expansions in the thermodynamic limit. It is established that perturbative continuous unitary transformations on white graphs are a promising and flexible approach to treat long-range interactions in quantum many-body systems. We exemplify this scheme for the one-dimensional transverse-field Ising chain with long-range interactions. For this model the elementary Quasiparticle gap is determined allowing to access the quantum-critical regime including critical exponents and multiplicative logarithmic corrections for the ferro- and antiferromagnetic case.

description: Ischemia and reperfusion (I/R) leads to oxidative stress with free radical formation. With respect to liver surgery and transplantation this can lead to deleterious clinical effects. Protection of the liver against I/R injury is of major concern. Thus, in this study, we examined the effect of an antioxidant vitamin solution (vitamin E, C and ß-carotene) on warm I/R injury. Twelve pigs of the German landrace (7 animals in the vitamin group and 5 untreated controls) were examined in this animal model. Twenty-four hours before laparotomy, the vitamin group was initiated with a single intravenous infusion of the vitamin cocktail. The duration of complete warm ischemia of the liver was 4 hours. Serum liver enzyme levels (AST and ALT) and with thiobarbituric acid reacting substances (TBARS) in liver tissue were measured. Furthermore, immunohistochemical staining of oxidative products (oxidized proteins and 4-hydroxy-nonenal = 4-HNE) in liver tissue was made. The maximum accumulation of oxidized proteins was seen six days postoperatively in the controls whereas in the vitamin group only small amounts were seen. 4-HNE showed a marked accumulation in the controls but was almost not detectable in the vitamin group. TBARS were lower in the vitamin group compared to controls. Although the emulsifier necessary for the vitamin solution leads to increased liver enzyme levels in the vitamin group, the values returned to normal more rapidly. Antioxidant vitamins are able to improve warm I/R liver injury. Oxidative stress is directly verifiable at the tissue level. Future animal experiments as well as clinical trials are necessary to explore the optimization of the combination of antioxidative vitamins for the maximum protection from I/R injury.

description: Σκοπός της μεταπτυχιακής διπλωματικής εργασίας ήταν η καταγραφή του αντιχολινεργικού φορτίου σε άτομα με ψυχικές διαταραχές και γνωστική έκπτωση. Πρόκειται για μία αναδρομική μελέτη παρατήρησης που διενεργήθηκε στην ψυχιατρική κλινική ενηλίκων του Γ.Ν.Θ. Γ.Παπανικολάου. Στη μελέτη συμπεριλήφθηκαν άτομα με ψυχικές διαταραχές που ανήκουν στο φάσμα των ψυχωσικών, διπολικών, καταθλιπτικών και ανοϊκών διαταραχών. Οι διαταραχές αυτές συνοδεύονται συχνά από γνωστική έκπτωση που επιμένει και στα διαστήματα μεταξύ των επεισοδίων της νόσου. Το υψηλό αντιχολινεργικό φορτίο έχει συσχετιστεί μεταξύ άλλων με έκπτωση των γνωστικών λειτουργιών. Υπολογίστηκε το αντιχολινεργικό φορτίο των ασθενών αυτών με βάση τη φαρμακευτική αγωγή εισόδου στην κλινική και την ACB scale. Τα αποτελέσματα που βρέθηκαν σχετικά με την αντιχολινεργική επιβάρυνση των ασθενών αυτών, τα φάρμακα τα οποία λάμβαναν (αντιψυχωσικά, βενζοδιαζεπίνες), τη διάρκεια χορήγησης των φαρμάκων (μακροχρόνια λήψη βενζοδιαζεπινών και μακροχρόνια αντιχολινεργική επιβάρυνση), και τη συμμόρφωση ή μη με τη φαρμακευτική αγωγή, συγκρίθηκαν με τα αποτελέσματα που βρέθηκαν από τη βιβλιογραφική αναζήτηση και με τις κατευθυντήριες οδηγίες για τη θεραπευτική προσέγγιση των διαταραχών αυτών
description: The purpose of this thesis was to record the anticholinergic burden of patients with psychiatric disorders and cognitive impairment. This was a retrospective observational study that was conducted at the psychiatric clinic of the general hospital of Thessaloniki G.Papanikolaou. The patients included in the study suffered from disorders that belong in the spectrum of psychotic, bipolar, depressive and dementia disorders. These disorders are often related with cognitive impairment that persists in times of remission. High anticholinergic burden is also related with cognitive impairment among other clinical outcomes. The anticholinergic burden was estimated using the ACB scale and the medicines that the patients were using at the time of the admission to the clinic. The results found regarding the anticholinergic burden, the medicines the patients were using (antipsychotics, benzodiazepines), the duration of treatment (long term use of bezodiazepines, high anticholinergic burden for more than three years), and the compliance with the treatment, were compared with the published literature and with the prescribing guidelines for those disorders.

description: The interaction of a quantum system, which is not accessible by direct measurement, with an external probe can be exploited to infer specific features of the system itself. We introduce a probing scheme based on the emergence of spontaneous quantum synchronization between an out-of-equilibrium qubit, in contact with an external environment, and a probe qubit. Tuning the frequency of the probe leads to a transition between synchronization in phase and antiphase. The sharp transition between these two regimes is locally accessible by monitoring the probe dynamics alone and allows one to reconstruct the shape of the spectral density of the environment.

description: Could tidal dissipation within Enceladus' subsurface ocean account for the observed heat flow? Earthlike models of dynamical tides give no definitive answer because they neglect the influence of the crust. I propose here the first model of dissipative tides in a subsurface ocean, by combining the Laplace Tidal Equations with the membrane approach. For the first time, it is possible to compute tidal dissipation rates within the crust, ocean, and mantle in one go. I show that oceanic dissipation is strongly reduced by the crustal constraint, and thus contributes little to Enceladus' present heat budget. Tidal resonances could have played a role in a forming or freezing ocean less than 100 m deep. The model is general: it applies to all icy satellites with a thin crust and a shallow ocean. Scaling rules relate the resonances and dissipation rate of a subsurface ocean to the ones of a surface ocean. If the ocean has low viscosity, the westward obliquity tide does not move the crust. Therefore, crustal dissipation due to dynamical obliquity tides can differ from the static prediction by up to a factor of two.

description: Acquired Immunodeficiency Syndrome (AIDS) has become a number one killer disease in Africa. The problem is believed to be so grave among government employees in general and teachers in particular; however, there are little hard data that substantiate the severity of the problem in these population groups . This cross-sectional study was aimed at assessing HIV/AIDS related mortality among primary and secondary school teachers. A total of 88 schools (66 primary and 22 secondary) were randomly selected for the survey and 193 deaths were identified. Complete data were obtained for 169 cases using verbal autopsy questionnaire. Verbal autopsies were reviewed by three physicians to determine the underlining cause of death. EPI-info version 6 and SPSS version 10 statistical packages were used to enter and analyze data. Proportions and rates were calculated to define the problem. Results showed that HIV/AIDS related illnesses were the leading cause of death accounted for 47.9% of all deaths. Tuberculosis was the major opportunistic infection in persons with HIV/AIDS, contributed for 88.9% of HIV related deaths. Mean age of death was 43.6 with SD 6.7. Most HIV related deaths (53.7%) were occurred in the age group 20-49 years (P= 0.015). Peak age of death was 35-39 years among males and 30-34 years among females for the year 2003. This shows that females have been dying at an earlier age compared to males. The likelihood of dying of HIV related illnesses was higher among widowed and divorced compared to the other groups (OR=4.74, 95% CI 1.14, 19.7). Most HIV related deaths (74%) had taken place at home, whereas 76% non-HIV related deaths were taken place in health institutions (P=0.009). ix In general HIV/AIDS was a cause for the majority of deaths and associated problems in both primary and secondary school teachers. Most teachers had died of the epidemic in their most productive age. Therefore it is advisable to make the teaching staff aware that they are being negatively affected by the epidemic. Further study with a more representative sample size is advisable since this study had limitation to get adequate sample size.

description: Η παρούσα μεταπτυχιακή διατριβή πραγματεύεται και παρουσιάζει τα τοπογραφικά όργανα και μέσα από τα οποία καθίσταται εφικτή η εξακρίβωση των χρήσεων γης. Δεν εμμένει μόνο στα παραδοσιακά τοπογραφικά μέσα, αλλά παρουσιάζονται και σύγχρονες μέθοδοι αποτύπωσης της γης. Τονίζεται τόσο η σημασία των χρήσεων γης αλλά όσο και η γνώση των χρήσεων γης επι συγκεκριμένης επιφάνειας. Η γνώση αυτή σαφώς και είναι σημαντική για την διαχείριση των οικοσυστημάτων προς μελέτη. Επίσης η εξακρίβωση διαδραματίζει σημαντικό ρόλο στην αποσαφήνιση πολλών ιδιοκτησιακών θεμάτων που προκύπτουν στην επικράτεια της χώρας μας. Επισημαίνεται ο ρόλος της φωτοερμηνείας και της τηλεπισκόπησης στην διαδικασία της εξακρίβωσης των χρήσεων γης. Τέλος, επιχειρείται και μια διερεύνηση του ρόλου που μπορούν να παίξουν τα μη επανδρωμένα ιπτάμενα οχήματα (drones) στην εργασία του δασολόγου της πράξης και στο τι μπορούν να προσφέρουν επιπλέον σε σχέση με τα παραδοσιακά μέσα εξακρίβωσης γης. Η εξέλιξη της τεχνολογίας μας παρέχει εργαλεία απαραίτητα για την βελτίωση της εργασίας μας, φέρνοντας και ταχύτερα αποτελέσματα.
description: This postgraduate dissertation deals with and presents the topographic instruments and through which it is possible to verify land uses. It not only insists on traditional topographic means, but also presents modern methods of mapping the land. The importance of land uses is emphasized, as well as the knowledge of land uses on a specific surface. This knowledge is clearly important for the management of the ecosystems to be studied. Verification also plays an important role in clarifying many property issues that arise in the territory of our country. The role of photo interpretation and remote sensing in the process of land use verification is pointed out. Finally, an investigation is attempted into the role that unmanned aerial vehicles (drones) can play in the work of the forester of the practice and what they can offer in addition to traditional land verification tools. The evolution of technology provides us with tools necessary to improve our work, bringing faster results.

description: Bisphenol A (BPA) is widely used in manufacturing industries. It is commonly detected in the environment and was reported to exert oestrogenic effects which may be harmful to the reproductive system. The present study was carried out to observe the effects of oral administration of BPA on the development of the reproductive organs and plasma sex hormone levels in prepubertal male Sprague-Dawley (SD) rats. Prepubertal male SD rats (n=8 in each group) were administered BPA in the doses of 1, 5, 10 and 100 mg/kg BW (body weight) via oral gavage for a period of 6 weeks. The control animals received the vehicle for BPA (Tween 80 in distilled water). Following 6 weeks of BPA exposure, the rats exhibited less evidence of spermatogenesis. There was seminiferous epithelial damage which included disruption of intercellular junctions and sloughing of germ cells into the seminiferous tubular lumen. Furthermore, the lumina of the seminiferous tubules and the epididymis of these animals were filled with immature germ cells and cellular debris. This damage may lead to the significant reduction in the seminiferous tubular diameter in BPA-treated animals. These findings were associated with the significant lower plasma testosterone and 17β-oestradiol levels. There was no significant difference between the body weight gain, the absolute as well as relative testis weight or epididymal weight of BPA-treated animals when compared to the control animals. The findings provided further evidence of the detrimental effects of BPA on the male reproductive system.
