The correlation between certain facial and dental measurements that influence dental aesthetics “Cephalometric study”

The purpose of the present study was to assess and determine if the correlation between certain facial measurements was significant to recommend their use as reliable aesthetic factors for selection of suitable tooth moulds for anterior teeth restoration. The materials for this study included 50 cephalometric radiographs for selected undergraduate students of Dentistry Collage, Mosul University; 25 males and 25 females. The age ranged from 18–25 years old with normal occlusion. The data were analyzed by using Minitab system and the result confirmed that certain facial measurements considered directly to determine the outline form to restore anterior teeth such as tooth width at the incisor edge, incisor tooth length, intercanine distance, the ratio of incisor tooth length and tooth width at the incisor edge, bi–incisors width, and bi–orbital width, while the others, bi–zygomatic width, intermolar distance, anterior facial height, and the ratio of anterior facial height and bi–zygomatic width, were indirectly indicated. Also there was a significant difference between male and female groups with different facial measurements. The ratio of the anterior facial height to bi–zygomatic width for the total sample was 0.93 mm, while that for the tooth length to tooth width was 0.81 mm. It could be concluded that certain facial measurements recommended as reliable aesthetic factors for selection of suitable tooth moulds for anterior teeth restoration.
Topics in computational finance

This paper presents, compares and evaluates the strengths and weaknesses of four Value at Risk (VaR) approaches for measuring risk, namely the delta normal, delta gamma, Monte Carlo simulation and historical simulation. The analysis was based on an option (non-linear) and on a stock (linear) portfolio, computing the four approaches to one and five days’ time horizon with 95% and 99% of confidence level. It was concluded that the Monte Carlo Simulation provides the most accurate risk measure and delivers consistent results for both portfolios. Although delta gamma provided an accurate VaR for the option portfolio, it also showed to be complex, demanding a higher level of calculation which can be costly and also complicated. On the other hand, the conclusions from the historical simulation for the two portfolios were overestimated because this one is based on historical data. Additionally, the delta normal method proved to be a weak model because it doesn’t present proper accuracy even for the stock portfolio. This is due to the fact that the delta normal method is based on normal distributions and, in practice, fat tails are more frequent than what the model predicts. Additionally, this paper proved the improvement that portfolio diversification can have in the VaR measures, being the Monte Carlo simulation the one that presents the highest efficiency in the VaR measures. Lastly, this work suggests an approach to improve the VaR measures when dealing with extreme values in the sample, that is Extreme Value Theory (EVT).
When 'Me' Trumps 'We': Narcissistic Leaders and the Organizational Cultures They Create CHARLES A. O’REILLY III Graduate School of Business Stanford University coreilly@stanford.edu

Researchers have become increasingly interested in how narcissistic leaders influence people and organizations. Research in this domain had generated equivocal results, however, with some studies showing that narcissistic leaders positively influence their firms because people are drawn to their grandiose visions, self-confidence, and bold actions, and other studies painting a more negative picture, showing that narcissists’ low integrity, lack of empathy, and individualistic orientation can lead them to put the organizations they lead at risk. We attempt to clarify these conflicting findings by suggesting that narcissistic leaders, through their signature attributes, create organizational cultures that can have a long term influence on firm value. In two field studies and two scenario studies, we show that more narcissistic managers: (a) prefer cultures that are lower on integrity and collaboration; (b) lead organizations with cultures that place less emphasis on integrity and collaboration; (c) endorse policies and procedures that are associated with cultures with lower integrity and less collaboration; and (d) have followers who are less likely to make decisions that support integrity and collaboration. We discuss the potentially lasting impact of narcissistic leaders on the cultures they cultivate.
The Investment Justification Estimate and Techno-economic and Ecological Aspects Analysis of the University Campus Microgrid

The paper presents the plan and design of the idea of the microgrid at the Faculty of Technical Sciences in Novi Sad (FTN NS) in the university campus, which is based on the application of several different distributed energy sources.

A retrospective study of incidence of dystocia in crossbred dairy cows

A retrospective study of incidence of dystocia was conducted on sixty dystocia cases in dairy crossbred cows presented to the Teaching Veterinary Clinical Complex, Veterinary College, Hassan. Out of sixty cases 36.67 and 63.33 percent were maternal and fetal causes of dystocia, respectively. Among the fetal causes, maldisposition of the fetus (38.33 percent) was the commonest cause of dystocia. Incomplete cervical dilatation (18.33 percent) was the major maternal cause of dystocia. Other causes of dystocia with low incidence include fetal emphysema, fetal oversize, fetal dropsy, fetal monster, uterine torsion, narrow pelvis and uterine inertia. A higher incidence of dystocia was recorded in primiparous compared to pleuriparous cow and it also associated with a male fetus compared to female fetus. Most of the cases were relieved pervaginally by mutation technique; uterine torsion was relieved by adopting modified Schaffer’s method. Caesarean section was performed in cases where pervaginal delivery is not possible.
Deep Learning for Synchronization and Channel Estimation in NB-IoT Random Access Channel

The central challenge in supporting massive IoT connectivity is the uncoordinated, random access by sporadically active devices. The random access protocol and activity detection have been widely studied, while the auxiliary procedures, such as synchronization, channel estimation and equalization, have received much less attention. However, once the protocol is fixed, the access performance can only be improved by a more effective receiver, through more accurate execution of the auxiliary procedures. This motivates the pursuit of joint synchronization and channel estimation, rather than the traditional approach of handling them separately. The prohibitive complexity of the conventional analytical solutions leads us to employ the tools of deep learning in this paper. Specifically, the proposed method is applied to the random access protocol of Narrowband IoT (NB-IoT), preserving its standard preamble structure. We obtain excellent performance in estimating Time-of-Arrival (ToA), Carrier-Frequency Offset (CFO), channel gain and collision multiplicity from a received mixture of transmissions. The proposed estimator achieves a ToA Root-Mean-Square Error (RMSE) of 0.99 us and a CFO RMSE of 1.61 Hz at 10 dB Signal-to-Noise Ratio (SNR), whereas a conventional estimator using two cascaded stages have RMSEs of 15.85 us and 8.05 Hz, respectively.

RELATIONSHIPS BETWEEN TEMPORAL AND SPATIAL VARIATIONS OF WATER QUALITY AND WATER LEVEL CHANGES IN POYANG LAKE BASED ON 5 CONSECUTIVE YEARS’ MONITORING

Quarterly water quality monitoring data from 15 monitoring sites in Poyang Lake and the water level data from the Xingzi monitoring station in Poyang Lake from 2012 to 2016 were analyzed to determine (1) how the water quality changed both spatially and temporally and (2) how the changes of the water quality and eutrophication were related to variations in the water level. The results indicated that there were seasonal and interannual variations in the water quality of Poyang Lake. Dissolved Oxygen (DO) and Total Nitrogen (TN) reached maximum and minimum values in winter and summer, respectively. The maximum and minimum concentrations of Total Phosphorus (TP) were found in spring and summer, respectively. Chemical oxygen demand (COD) was slightly lower in spring and summer than in autumn and winter. Over the entire sampling period, the concentrations of ammonia nitrogen (NH4-N), TP, and TN were highest in 2015. COD concentrations varied little interannually. Chlorophyll a concentrations were relatively uniform and did not show obvious seasonal variation. There was little spatial variation in the NH4-N concentrations in spring and summer, but there was considerable variation between sites in autumn and winter; COD varied considerably between sites in spring and winter. COD and TP were not significantly correlated, but NH4-N, TN, and the degree of eutrophication were negatively correlated, with water level changes in Poyang Lake.
Antihyperlipidemic Effect of Sarabat (Diplazium polypodiodes Blume.) Aqueous Extract in Diet-Induced Hyperlipidemic Rats

Hyperlipidemia remains an important modifiable risk factor in cardiovascular diseases. The aim of the present study was to investigate the potential role of the aqueous decoction of Sarabat (Diplazium polypodiodes Blume) in lowering plasma lipid profile in albino rats fed a high fat diet (HFD). Thirty Wistar albino rats were randomly divided into five groups of six rats and for 42 days were administered plain water and standard pellets (negative controls), lard and cholesterol (hypercholesterolemic animals), low and high dose Sarabat decoction (1and 2 g/100ml water respectively and Simvastatin as positive control. The effects of D. polypodiodes Bl. (Sarabat) decoction on rat lipid profiles was assessed by measuring the plasma Total cholesterol (TC),triglyceride (TG),Low density Liporprotein (LDL), High Density Lipoprotein (HDL) and Very Low Density Lipoprotein (VLDL) . Administration of lard and cholesterol showed a significant elevation (p<0.006) of cholesterol during the third data gathering (week 4) and similarly for the other lipid parameters with an increasing lipid profile after a two-week metabolic adjustment period. Concurrent administration of Sarabat (D.polypodiodes Bl.) decoction showed a promising decrease in cholesterol serum concentration(p<0.006) , an increase in High Density Lipoprotein (HDL) was notable although not statistically significant. These findings suggest the cholesterol and lipid buffering effects of saponin rich Sarabat as potentially useful in the management of hyperlipidemia as part of diet
Gordon Dry Gin (Moringa Citrus Blend) Induce Adenomatous Hyperplasia in Female Sprague Dawley Rats

Objectives: This study aim to investigate the histopathological effects of binge consumed Gordon’s dry gin moringa citrus blend on the uterus of adult female dawley Sprague rats. Materials: Fifty female rats (weighing range; 120±2.6 g - 250±3.5 g) were divided into four groups (A, B and C & D). Group A, B, C (15 animals each) were orally administered with Gordon’s dry gin moringa citrus blend, 43% ethanol, and 200 mg/kg moringa extract, respectively, while Group D (5 animals) did not receive any treatment and was used as negative control. In groups A, B, and C, five animals were sacrificed on the 7th, 14th and 21st day of administration, whereas animals of group D were sacrificed on day 21. The uterus of each rat was harvested, processed and stained with haematoxylin and eosin solution for histological analysis. Results: Results of the study revealed histological alterations in the uterus of treated animals. Such alterations include adenomatous hyperplasia and cystic hyperplasia. Conclusion: The oral administration of gordon’s dry gin moringa citrus and moringa extract at 200 mg/kg induced cystic and adenomatous hyperplasia in rat uterus, inferring that both gordon dry gin and moringa might yield antifertility activity.
Equine sarcoids - part 1: clinical presentation and epidemiology

Equine sarcoids are the most common skin tumors in horses and other equids. In their pathogenesis, the bovine papillomavirus (BPV) plays a major role. Many clinical manifestations have been described, ranging from small single lesions to multiple aggressively growing masses. Histopathologically, it is considered as a biphasic tumor with epidermal hyperplasia and subepidermal proliferation of transformed fibroblasts. The diagnosis can be made clinically, histopathologically and/or by detection of BPV DNA. Sarcoids can appear on any part of the body, but they are mostly localized on the ventral abdomen, the paragenital region, head and limbs. Sarcoids occur independent of breed, coat color, sex or age, but they develop more commonly in young adults and certain families and breeds are more vulnerable than others. Transmission of BPV is supposed to happen from cattle to horse or from horse to horse, possibly via insects.
REDUCED FILE HASH FOOT PRINTS FOR OPTIMIZED DEDUPLICATION IN CLOUD PLATFORMS

Cloud Data Storages decreases colossal burden on clients as for their neighborhood stockpiles yet acquaints new issues with deference with information copies in the cloud. Albeit some prior methodologies managed the issue of actualizing a way to deal with handles cloud security and execution as for de-duplication by appropriately characterizing the concerned gatherings in the cloud and summoning document signature distinguishing proof procedure utilizing customary hash message validation code (HMAC). Because of these hash code calculations like SHA-1 and MD5 the document trustworthiness qualities are colossal prompting idleness variable at the de-duplication estimation. Because of this above issue the capacity exhibit obliges earlier trustworthiness hash codes prompting execution issues. In this paper, we propose a Genetic Programming way to deal with record deduplication that joins a couple of unmistakable bits of affirmation removed from the information substance to discover a deduplication limit that has the limit perceive whether two sections in a store are duplicates or not. As appeared by our trials, our methodology beats a current cutting edge technique found in the writing. Additionally, the proposed capacities are computationally less requesting since they utilize less confirmation. Furthermore, our hereditary programming methodology is prepared to do consequently adjusting these capacities to a given settled copy ID limit, liberating the client from the weight of choosing and tune this parameter.
Temporal Strategies of Student Educational Activeness: Strategic Capital or Basic Resource?

The relevance of this article lies in the understanding of strategic guidelines by students. In today's world, when social time is accelerating every year, it is becoming increasingly difficult to navigate in personal and public time. Solving life problems , it is necessary to pay attention to planning and proper allocation of time, as years later there is a great risk to consider the pa st years lost. Timely realization of the opportunities and potential is important when the person has both forces, and time, and it is the period of youth. The aim of the study is to analyze the temporal strategies of personality in the field of educational activeness. The article studies the features of educational activeness of students. Cognitive, emotional and behavioral aspect s of students' temporal strategies are analyzed. The novelty and originality of the study lies in the fact that the features of educational activeness of students are studied. It is shown that the majority of students in training focuses on obtaining a diploma and subsequent employment. It is revealed that some students believe that they need education for the sake of self -realization and knowledge. It is established that students have the most common professional and cognitive goals. Cognitive aspects of s tudents' temporality are investigated. It is revealed that students perceive time in quite similar categories as the reserve of a resource that is all ocated to them and which they can dispose of as a limited reserve that they dispose of during their lives. It is established that some students see the possibility of time control. It is shown that time for a significant part of students is not a strategic capital that implements life plans. The data obtained in the work can be used in labor psychology, age psychology, social psychology, pedagogy, sociology, as well as for further theoretical development of this issue.

Shrinkage of muscular layer as well as ulceration was prominent. Ulceration and compression of muscular fibres was observed in a number of sections. It is the first report on intestinal tissue damage caused by acanthocephalan Polymorphus mohiuddini Rahman et al., 2008 in owl.
Assessing Legislative Alignment – An Ontological Approach Work in progress

An ontology provides the agreed definitions and describes how the terms in a subject area or domain, are related. It is a model that can be read by humans and coded for use by computers. Across the globe, governments are using ontologies in innovative ways to solve long-standing government problems. The problem is that there is no single approach used by government agencies to assess whether their systems are aligned to the legislation. In a social welfare setting, if there is any misalignment between the legislation and the systems, then, it may result in an unintentional disadvantage to those most in need. This paper outlines the research design using a case study to detect and to compare the ontological patterns existing in legislation and an online claim form relating to a family tax benefit in Australia. Keywords-Ontology; Ontology alignment; Legislation; Government claim forms; Online claim forms.
Uncoupling Protein 2 (UCP2) and p53 Expression in Invasive Ductal Carcinoma of Breast

Background : Uncoupling protein 2 (UCP2) is a recently identified mitochondrial inner membrane anion carrier and a negative regulator of reactive oxygen species production. In this study, we evaluated the characteristics and relationships of UCP2 and p53 expression in breast cancer tissues. Methods : Tissue microarray slides from 107 cases of invasive ductal carcinoma of the breast were constructed, UCP2 and p53 immunohistochemical staining was conducted, and clinicopathological correlations were investigated. Results : UCP2 expression in invasive ductal carcinoma was high in 53 cases (49.5%), while p53 expression in invasive ductal carcinoma was high in 37 cases (34.6%). UCP2 expression was correlated significantly with histological grade (p = 0.038) and mitotic count (p = 0.050). UCP2 expression was correlated significantly with p53 expression in invasive ductal carcinoma of the breast (p = 0.045). UCP2 expression (p = 0.8308) and p53 expression (p = 0.3292) showed no significant difference for the overall survival rate in patients with invasive ductal carcinoma. Conclusions : UCP2 expression in invasive ductal carcinoma increased proportionally with histological grade and mitotic count. High UCP2 expression in invasive ductal carcinoma was observed in conjunction with high p53 expression.
