Leukocytoclastic Vasculitis and Renal Cell Carcinoma

54 Cebeci et al., Leukocytoclastic Vasculitis and Renal Cell Carcinoma / doi: 10.14744/hnhj.2017. 87004 were detected in the left paraaortic area. A punch biopsy of the rash showed findings characteristic of leukocytoclastic vasculitis: fibrinoid deposits around the vessel wall with perivascular neutrophilic infiltrates in the cutaneous postcapillary venules, endothelial swelling, and erythrocyte extravasation (Fig 2a, b). The patient was diagnosed with LCV and treated with oral antihistamine and leg elevation. He was referred to a urology clinic for simple nephrectomy surgery, and pathological examination of the mass revealed RCC. The vasculitic skin lesions disappeared after surgical treatment, and the general health of the patient was good during a follow-up period of 3 years. The clinical course of vasculitides is variable, and etiologies or associated conditions are diverse. Some vasculitides can caused by allergy, drugs, rheumatic and/or autoimmune diseases, and infections. In some patients, vasculitis occurs during the course of or prior to malignancies, most often hematogenous malignancies such as leukemia and lymphoma rather than solid tumors [3]. Various mechanisms have been proposed for tumor-associated LCV, including antigen–antibody complexes that form in response to tumor antigens and are deposited in the vessel walls, resulting in inflammation [4]. Malignancy plays a role in 5% of patients with LCV [5]. In conclusion, LCV might be a marker for malignancy, especially in unexplained cases. Early recognition of LCV associated with underlying malignancy may lead to more timely diagnosis, more successful treatment, and increased survival. We believe that in apparently idiopathic LCV, screening examination should be performed to detect any underlying early-stage curable solid malignancy. Consequently, patients who present with vasculitis of unknown cause, especially in those aged ≥50 years, should be investigated for an associated hidden malignancy.

Understanding of state capacity in civil war onset, 1984-1999

Scholars have used multiple approaches to investigate civil war. Among various civil war studies, those examining civil war onset are important because onset is the first stage of war. In the early stage of civil war onset research, scholars focused on the motivation for rebellion. However, these studies overlooked the role of the state. Attempting to remedy this lack, this study investigates the role of the state as a main actor in the process of civil war onset, considering it in terms of state capacity with two indicators: bureaucratic quality and government stability. This study tests these indicators by examining the onset of two scales of civil wars: large and small. The results confirm that state capacity influences civil war onset. However, the impact of state capacity depends on the scale of civil wars.
Quantum Dot-sensitized Solar Cells: A Review

Quantum dot-sensitized solar cell (QDSSC) has an analogous structure and working principle to the dye sensitizer solar cell (DSSC). It has drawn great attention due to its unique features, like multiple exciton generation (MEG), simple fabrication and low cost. The power conversion efficiency (PCE) of QDSSC is lower than that of DSSC. To increase the PCE of QDSSC, it is required to develop new types of working electrodes, sensitizers, counter electrodes and electrolytes. This review highlights recent developments in QDSSCs and their key components, including the photoanode, sensitizer, electrolyte and counter electrode.
Attitudes and motivation of deaf and hard of hearing students for studying

The aim of this paper was to determine the attitudes and motivation for reading/writing and studying of deaf and hard of hearing (DHH) students and the relation of those attitudes and motivation to success at school. The sample included 47 DHH students, of both genders, 14 to 18 years of age. The Scale for examining interests and aspiration of students (Suzic, 2003) was used. The Scale consists of eight subscales with 20 statements/indicators of attitudes for activities: studying, sports, music, TV, entertainment, reading/ writing, love and dating, and social work. Ten statements refer to involvement in aforementioned activities and another ten refer to possibilities provided by those activities. Attitudes to reading/writing and studying were assessed and the correlation between those attitudes and the general school success was established. Data was processed by descriptive analysis, and Spearman's correlation coefcient was calculated. The result was a moderate correlation between DHH students' attitudes to reading/writing (ρ=0.61) and studying (ρ=0.55) and their general school success, and a moderately strong correlation between the perceived possibilities offered by these activities (reading/writing - ρ=0.46 and studying - ρ=0.36) and the general school success, at a significance level of p<0.05. According to survey results, it has been established that DHH students who understood the significance of reading, writing and studying better had more positive attitudes, were more involved in these activities, and thought they provided them with better possibilities. Furthermore, their motivation for studying was higher, as confirmed by their higher academic achievement.
Modeling terrestrial carbon and water dynamics: A critical appraisal and ways forward

Terrestrial carbon and water balances and their variability under changing climatic conditions and anthropogenic disturbances are topics of great societal and scientific importance. The role of vegetation in shaping carbon and water dynamics is of paramount significance. Many numerical models, reflecting different degrees of complexity and abstraction, have therefore been developed to mimic plant function. The aim of this thesis is to (i) shed light on how vegetation functioning is simulated in state-of-the-art terrestrial ecosystem models, (ii) provide a critical appraisal of model strengths and weaknesses, and (iii) present ways forward to remove some of the identified model limitations. The first part of the thesis provides a thorough evaluation of a state-of-the-art, process-based, dynamic vegetation model, LPJ-GUESS, by means of a global sensitivity analysis. The rationale is that since process-based models embed physical causalities, the sensitivity of the simulated processes should also reflect measurable and observed sensitivities. Having scrutinized the structural and parameterization issues underlying LPJ-GUESS, reflecting also that of other, structurally similar dynamic vegetation models, the subsequent parts of the thesis are devoted to two major model limitations, namely (1) the lack of spatial representation and simplified soil water hydrology, and (2) the lack of ecological realism due to simplified representation of plant trait variability. The former limitation is analyzed with a novel ecohydrological scheme, D-LPJ, which is based on an iterative coupling between a spatially explicit, processbased hydrological model (TOPKAPI-ETH) and a well-established dynamic vegetation model (LPJ). The advantages of D-LPJ over the original, aspatial approaches of LPJ and LPJ-GUESS are illustrated for a topographically-complex area located in the central Switzerland. The aggregation-induced biases due to smoothing of spatial heterogeneities through coarse-grained aspatial representations are also explicitly quantified. The second limitation is investigated with an innovative Monte Carlo approach that is applied to simulate the diversity of plant traits. This approach revises the broad vegetation categories, based on a discrete and static parameterization (named Plant Functional Types), often incorporated in terrestrial ecosystem models. Proxy plant species are generated using observed multivariate distributions of coordinated plant traits. Their performance is assessed with a mechanistic ecohydrological model (T&C) across continuous, naturally occurring, meteorological gradients in the European Alps. The significant importance of traitinduced variability in simulating water and carbon dynamics is quantified and
Bioleaching of low-grade copper ore using indigenous microorganisms

Investigations have been carried out on the iron oxidation rate of Acidithiobacillus ferrooxidans, the bacteria used in bioleaching process. It was observed that the regeneration time of the bacteria is reduced from 168 to 16 h by repeated subculturing, which in turn gave rise to higher iron oxidation rate thus increasing the kinetics of the process. This active strain was utilized for bioleaching of low-grade copper ore by varying two parameters namely, pH and pulp density. It was observed that around 30% of copper could be leached at an initial pH and pulp density of 2 and 20% (m/v) respectively.
IMPORTANCE OF LEADERSHIP AND ENTREPRENEURSHIP FOR THE PERFORMANCE OF THE POULTRY SECDTOR IN ARGENTINA

The Argentine “industrial aviculture” started by 1960. The great development of the poultry sector was during the 1990s as a consequence of the direct price transfer due to technological and organizational improvements achieved in the sector. The objective of this paper is to identify how leadership and entrepreneurship have been important elements in the development of the Argentine poultry sector. The poultry sector is one of the faster development in Argentina and one that offers higher quality. This was achieved only because of great coordination due to leadership and entrepreneurship both at micro and macro level.
Seasonal differences in diversity of macroinvertebrate and fish taxa in a Midwestern stream

Most biomonitoring projects focus on single species groups at time scales either too short or too coarse to detect intra‐annual oscillations in biodiversity. Using a multifaceted approach, we compared diversity indices of larval macroinvertebrate families and fish species in a Midwestern stream during spring and fall of 2009–2013 and discovered contrasting patterns in α and β diversities between the seasons for the two taxa groups. Compared with spring, both α and β diversities were significantly higher during fall for macroinvertebrates; on the contrary, only α diversity differed between the seasons for fishes. For both taxa, we partitioned the overall β diversity to identify contributions of temporal and spatial β diversities on the observed differences. The observed patterns for macroinvertebrates were likely the result of season acting as environmental filter, but stochastic dispersal and recruitment processes were likely more important in driving fish diversity patterns. In light of widespread conservation and restoration efforts in the Midwestern streams, it seems prudent to study community composition frequently so that baseline α and β diversities can be obtained for organisms at different taxonomic levels and during different seasons.
ASPECTS OF GEOMETRIC QUANTIZATION THEORY IN POISSON GEOMETRY

This is a survey exposition of the results of (14) on the relationship between the geometric quantization of a Poisson manifold, of its symplectic leaves and its symplectic realizations, and of the results of (13) on a certain kind of super-geometric quantization. A general formulation of the geometric quantization problem is given at the beginning. 1. The general setting. This is a report on results which I obtained in the subject during the last years (13), (14). But, I will start with a general formulation of the geometric quantization problem. A general algebraic formulation was developed by Huebschmann (4). In this exposition the manifolds and bundles will be nite dimensional, and everything will be of class C 1 . Let M be a manifold, and A ! M a Lie algebroid with the anchor a : A ! TM (12). A generalized, A-valued, Hamiltonian structure on M is a Lie algebra structure f ; g on C 1 (M), together with a Lie algebra morphism
Explaining the Willingness of Public Professionals to Implement Public Policies: Content, Context and Personality Characteristics

The willingness of public professionals to implement policy programmes is important for achieving policy performance. However, few scholars have developed and tested systematic frameworks to analyze this issue. In this study, we address this by building and testing an appropriate framework. The aims have been: (1) to build a three-factor model (policy content, organizational context, and personality characteristics) for explaining willingness to implement policies; and (2) to quantitatively test the model through a survey of Dutch professionals. The results show that policy content is the most important factor in explaining willingness. Nevertheless, organizational context and the personality characteristics of implementers also have a significant effect and should be considered when studying the attitudes of professionals towards policies. This research helps in understanding the willingness or resistance of professionals when it comes to implementing policies.

Fatty acids composition in South African freshwater fish as indicators of food quality

Lipid classes and fatty acid composition of three commercially important freshwater fish species Oreochromis mossambicus (Mozambique tilapia), Clarias gariepinus (African catfish) and Cyprinus carpio (carp) obtained from an aquaculture, different river systems and fish markets from different provinces in South Africa were investigated. Fatty acids were extracted from the fish fillets through the Folch extraction method (using chloroform: methanol at the ratio of 2:1). Generally, tilapia fish species was found to be the richest in fatty acid composition. In all fish species analysed, palmitic acid (16:0) was found to be the most abundant fatty acid ranging from 18.24 to 21.84%. Appreciable quantities of essential polyunsaturated fatty acid such as docosahexaenoic (DHA) (22:6 n-3, 3.92 to 6.16%), eicosapentaenoic acid (EPA) (20:5 n-3, 1.91 to 2.92%) and arachidonic acid (20:4 n-6, 7.19 to 8.50%) were also found. Observations show that fish species obtained from Gauteng Province are richer in fatty acids compared to those in Limpopo Province. The study points out that all fish species investigated contain appreciable levels of Omega-3 (n-3) polyunsaturated fatty acids (PUFA) and are therefore suitable for an unsaturated low-fat diet. This is important especially for poor communities who cannot afford to get a balanced diet, rich in some essential fatty acids.Therefore, it is important to determine the nutritional value of local fish, since it significantly contribute to a healthy diet in rural communities.
Capital Structure and Financing Choices in Australia

We use a modified pecking order framework to analyse financing choices for Australian firms. The traditional pecking order model has been extended to allow a non-linear relationship between a firm’s requirements for external capital (the financial deficit) and the amount of external debt used to meet these requirements. The pecking order theory predicts that firms will follow a defined hierarchy of financing choices with internal funds being used first, followed by external debt and as a last resort the issuance of external equity. Our main finding is that Australian firm’s do not follow the pecking order as closely as in other markets as the model explains less of the variation in debt issuance. Importantly, we find that this is not related to debt capacity constraints, which has been hypothesized by other researchers as a legitimate reason why firms, small firms in particular, would not appear to be following the pecking order theory. We use Altman’s Z-Score, which is a commonly used measure of financial distress, to identify firms that are relatively unconstrained in terms of debt capacity. We also find that while controlling for debt capacity does improve the explanatory power of our model, the improvement is only marginal. We do find evidence against the static trade-off theory of capital structure. In particular firms that are unconstrained in terms of debt capacity and not facing significant capital expenditure do not increase leverage towards an optimal capital structure in the manner predicted by the static trade-off theory. We hypothesize that at least part of the reason for these findings is due to taxation differences, with the imputation credit system in Australia effectively removing the tax advantage of debt for domestic investors. Another important factor that could explain the lower explanatory power of the pecking order model could be the more accepted use of warrants and rights issues to raise equity, which have been argued to have lower asymmetric information costs than issuing straight equity.
Vessel Detecting using Restrict Single Shot Multibox Detector for Intravascular Ultrasounds

Intravascular ultrasounds (IVUS) is a technique in scanning coronary artery, which is extensively used in interventional therapy and it can provide valuable clues in detecting coronary plaques. Nevertheless, up to now, most of the image frames of IVUS are manually examined by physicians. In this paper we designed a restrict single shot multibox detector(R-SSD) method to automatically locate the regions of interests, e.g. vessel, for computer-aided IVUS examination, by changing the initial feature extraction network and restricting the range of prior box of original SSD method dedicated for object recognition. The accuracy on locating vessel can achieve 95.4% using the proposed R-SSD.
Development of new approaches for assessing miscibility and the solid state structure of olanzapine dispersions in polymeric carriers

Drug-polymer dispersions are a well-established formulation strategy, with many commercial products utilising this technology to either increase bioavailability of poorly water soluble compounds or produce controlled release systems. The main limitation of these formulations is their long-term physical stability since these systems are often unstable supersaturated molecular dispersions. This instability can lead to recrystallisation of the drug, potentially affecting the dissolution performance. In this work, new analytical methods were applied to provide understanding into the crystallisation behaviour of a model drug, olanzapine, in several polymer dispersions. The intention was to develop new insights into the physical drivers for crystallisation, the means by which it can be detected and predicted, and the possibility of utilising this knowledge to manipulate the crystal form. Olanzapine-loaded poly(lactic-co-glycolic acid) (PLGA) microparticles were initially produced. The physical stability of this system was assessed through drug-polymer solubility measurements. Several de-mixing approaches were compared in which supersaturated dispersions were recrystallised to achieve the equilibrium solubility level of the drug in the polymer phase. During this work a quasi-isothermal modulated temperature differential scanning calorimetry (QiMTDSC) protocol was developed and applied to study crystallisation in these systems. Drug-polymer solubility was successfully measured using this approach and drug crystallisation could also be monitored, allowing investigation of the conditions under which the solubility equilibrium could be achieved. Olanzapine is a polymorphic molecule and the study of its recrystallisation in PLGA dispersions highlighted that standard techniques could not determine which form was crystallising. Thus, a new simultaneous differential scanning calorimetry-powder X-ray diffraction (DSC-PXRD) method was applied to characterise olanzapine crystallisation in several polymer dispersions. Interestingly, drug crystallisation was influenced by the different polymers present. A new polymorph, olanzapine form IV, was discovered which indicated that this crystallisation approach can be used as an alternative method for polymorph screening. A process was developed to extract form IV crystals from the polymer matrix, providing the proof-of-concept that this approach can be used to generate and isolate new polymorphic forms.
The Relation between Firm-Level Corporate Governance and Market Value: A Study of India

Relatively little is known about the corporate governance practice of firms in emerging markets. We provide a detailed overview of the practices of publicly traded firms in India, and identify areas where governance practices are relatively strong or weak. We also find cross-sectional evidence of a positive relationship between firm market value and an overall governance index, as well as a subindex covering shareholder rights. The association is stronger for more profitable firms and firms with stronger growth opportunities.
