Anisotropic Mechanical Properties of ABS Parts Fabricated by Fused Deposition Modelling

Layered manufacturing (LM) methods have traditionally been used for rapid prototyping (RP) purposes, with the primary intention of fabricating models for visualization, design verification, and kinematic functionality testing of developing assemblies during the product realization process (Caulfield et al., 2007). Without any need for tooling or fixturing, LM allows for the computer-controlled fabrication of parts in a single setup directly from a computerized solid model. These characteristics have proven beneficial in regard to the objective of reducing the time needed to complete the product development cycle (Chua et al., 2005).
Evaluation of the regenerative effect of a 25% doxycycline-loaded biodegradable membrane for guided tissue regeneration.

BACKGROUND Biodegradable materials have been successfully utilized for guided tissue regeneration (GTR) and local delivery systems (LDS) because they are biocompatible, less cytotoxic, and do not require removal. Several studies have demonstrated that tetracyclines (TCs), when applied topically, stimulated osteogenesis in experimental bone defects. The purpose of this study was to evaluate the regenerative effect of a 25% doxycycline-loaded biodegradable GTR membrane (Doxy-M) in dogs. METHODS Doxy-M was made by coating the inner surface of a biodegradable membrane (BD-M) with 25% doxycycline. Five male mongrel dogs with 20 created osseous defects were enrolled. The plain BD-M was used as the control membrane. Either Doxy-M or BD-M was applied in 20 randomly selected defects (10 Doxy-M, 10 BD-M) for 12 weeks with the GTR technique. The histometric analysis was evaluated with the following parameters: defect height (DH), apical extension of junctional epithelium (AEJP), new cementum height (NCH), new bone height (NBH), and new bone area (NBA). RESULTS The Doxy-M-treated defects showed more pronounced new bone formation and less crestal bone resorption than the BD-M-treated defects. There were no statistically significant differences between the two groups in DH, AEJP, and NCH. Statistically significantly larger NBH (P <0.05) and NBA (P<0.005) were seen in the Doxy-M-treated defects. CONCLUSIONS The results strongly suggest that Doxy-M may have a beneficial effect on osteogenesis to favor periodontal regeneration.
Coeliac trunk and its branches: anatomical variations and clinical implications.

INTRODUCTION Knowledge of anatomical variations of the great vessels of the abdomen, including the coeliac trunk, is important for clinicians planning surgical intervention and radiological imaging. The present study aimed to record the prevalence of variations in the vascular pattern of branches of the coeliac trunk in cadavers. METHODS A total of 50 properly embalmed and formalin-fixed cadavers from the Indian population were selected for the study. Dissection included surgical incision, followed by mobilisation of the anatomical viscera, to observe and record the branching pattern of the coeliac trunk. RESULTS The left gastric, common hepatic and splenic arteries were found to arise from the coeliac trunk in 86% of cadavers. In 76% of cadavers, the origin of the gastric artery was proximal to the bifurcation of the coeliac trunk into the common hepatic and splenic arteries. In one case, all three branches arose directly from the abdominal aorta, and the origin of the splenic artery was 1 cm distal to the origin of the left gastric and common hepatic arteries. In another case, the common hepatic and left gastric arteries arose from the coeliac trunk, and the origin of the splenic artery was 1.5 cm distal to the abdominal aorta. CONCLUSION Vessel ligation and anastomosis are important in surgical procedures like liver transplantation, and background knowledge of the different vascular patterns of branches of the coeliac trunk is vital. The findings of our study could help to minimise complications related to abdominal surgery, including bleeding and necrosis, and facilitate better and more accurate radiological interpretations.
IPO Underpricing and Ownership Structure : A Comparison of Family Firms and Non-Family Firms

Underpricing in an Initial Public Offering (IPO) is often used as a means of retaining control of the company when going public. Therefore, first day returns post-IPO can be substantial for investors. Ownership structure is directly linked to IPOs where in particular family control is interesting due to the special link families have to their firms. Sweden has a great portion of family firms and is also the country that uses dual class share structures to the largest extent. With this study, we examine family control in terms of voting rights related to initial returns for IPOs. Additionally, we investigate this relation with regards to family firms and non-family firms and the usage of dual class share structures. This is conducted by using a hand-collected data set of 165 Swedish IPO firms between years 2000-2015. The results indicate that family firms use dual class share structures to a larger extent than non-family firms. In addition, it indicates that family firms use dual class share structures instead of underpricing the share in order to retain control of the company.
Secretin effects on cerebellar-dependent motor learning in schizophrenia.

OBJECTIVE Pervasive cognitive deficits in schizophrenia are a major cause of disability among individuals with the disorder. One such deficit is the loss of effective associative learning, which is readily assessed via eye-blink conditioning procedures. The authors examined the efficacy of secretin, a hormonal agonist for the prototype group B G-protein-coupled receptors, in ameliorating eye-blink conditioning deficits in schizophrenia patients. METHOD Immediately following a pretreatment delay eye-blink conditioning recording session, 25 individuals with schizophrenia received either secretin (RG1068; 20 microg/kg [N=15]) or a saline placebo (20 microg/kg [N=10]) subcutaneously in a double-blind fashion. Comparison groups were formed by yoking pairs of subjects on the basis of performance during the pretreatment baseline eye-blink conditioning recording session, and thus 20 subjects underwent further analysis. Secretin was selected because eye-blink conditioning depends on the release of Purkinje cell inhibition on deep nuclei of the cerebellum and recent findings indicate that secretin is endogenously released in the cerebellum, where it acts as a retrograde messenger and neuromodulator on basket and Purkinje cells. RESULTS Eye-blink conditioning was significantly improved at 2 and 24 hours after secretin administration but not after treatment with placebo. These results are consistent with evidence of intracellular signaling abnormalities in the pathophysiology of schizophrenia and indicate a possible role for secretin in modulating cerebellar-mediated classically conditioned learning. CONCLUSION If cerebellar abnormalities in individuals with schizophrenia are associated with fundamental mechanisms and symptoms of the disorder, as suggested by the cognitive dysmetria model, then cerebellar-targeted treatments may provide a novel approach to treatment for schizophrenia.
Short-term fate of rehabilitated orphan black bears released in New Hampshire

We evaluated the release of rehabilitated, orphan black bears (Ursus americanus) in northern New Hampshire. Eleven bears (9 males, 2 females; 40–45 kg) were outfi tted with GPS radio-collars and released during May and June of 2011 and 2012. Bears released in 2011 had higher apparent survival and were not observed or reported in any nuisance behavior, whereas no bears released in 2012 survived, and all were involved in minor nuisance behavior. Analysis of GPS locations indicated that bears in 2011 had access to and used abundant natural forages or habitat. Conversely, abundance of soft and hard mast was lower in 2012, suggesting that nuisance behavior, and consequently survival, was inversely related to availability of natural forage. Dispersal from the release site ranged from 3.4–73 km across both years, and no bear returned to the rehabilitation facility (117 km distance). Rehabilitation appears to be a valid method for addressing certain orphan bear issues in New Hampshire.
Predictors of Obstructive Sleep Apnea-Hypopnea Treatment Outcome

Oral appliance therapy is an alternative to continuous positive airway pressure (CPAP) for treating the obstructive sleep apnea-hypopnea syndrome. However, the ability to pre-select suitable candidates for either treatment is limited. The aim of this study was to assess the value of relevant variables that can predict the outcome of oral appliance and CPAP therapy. Fifty-one patients treated with oral appliance therapy and 52 patients treated with CPAP were included. Relevant clinical, polysomnographic, and cephalometric variables were determined at baseline. The predictive value of variables for treatment outcome was evaluated in univariate and multivariate analyses. The outcome of oral appliance therapy was favorable, especially in less obese patients with milder sleep apnea and with certain craniofacial characteristics (mandibular retrognathism in particular). Neither univariate nor multivariate analyses yielded variables that reliably predicted the outcome of CPAP. We conclude that the variables found in this study are valuable for pre-selecting suitable candidates for oral-appliance therapy.
Multidimensional Liquidity: Evidences from Indian Stock Market

Various dimensions of liquidity including breadth, depth, resiliency, tightness, immediacy are examined using BSE 500 and NIFTY 500 indices from Indian Equity market. Liquidity dynamics of the stock markets were examined using trading volume, trading probability, spread, Market Efficiency coefficient, and turnover rate as they gauge different dimensions of market liquidity. We provide evidences on the order of importance of these liquidity measures in Indian stock market using machine learning tools like Artificial Neural Network (ANN) and Random Forest (RF). Findings reveal that liquidity variables collectively explains the movements of stock markets. Both these machine learning tools performs satisfactorily in terms of mean absolute percentage error. We also evidenced lower level of liquidity in Bombay Stock Exchange (BSE) than National Stock Exchange (NSE) and findings supports the liquidity enhancement program recently initiated by BSE.
Personal Communities: Not Simply Families of ‘Fate’ or ‘Choice’

Starting from a simple model of personal relationships based on degrees of commitment and degrees of choice, the authors explore the relative importance of repertoires (the range of friendship types in which people engage), friendship modes (the way in which people make, retain or lose friends throughout the life course) and patterns of suffusion (the extent to which friends and family play overlapping or specialized roles), and these concepts form the basis of a typology of personal communities. Analysis of ‘suffusion’ between ‘friends’ and ‘family’ showed considerable blurring of boundaries. The authors challenge assumptions about familial and non-familial ties. Empirical findings demonstrate the diversity and significance of contemporary personal communities and rebut the postmodernist thesis that people are isolated, individualized and lacking in strong and enduring personal relationships.
Concentration of Ukraine’s Banking System: Myths and Facts

This article attempts to find answers to questions of current significance: How concentrated is Ukraine’s banking system from the viewpoint of the world’s best regulatory practices and in comparison with other countries? What has been the driving force behind the growing concentration in recent years and does this process pose a threat to competition in the banking system? What effect would mergers and acquisitions in the banking sector have on the concentration of the banking system? And finally, do public authorities have to stimulate consolidation in the banking system or, on the contrary, restrain potential bank mergers and acquisitions? The results of empirical analysis dispel the persisting myths about the risks of fast and excessive concentration resulting from continuing market consolidation and about the substantial impact of inequality on the growing concentration, and refute the perceived danger of mergers and acquisitions in the banking sector. Instead, it was discovered that concentration of banking assets in Ukraine is not substantial according to the Herfindahl–Hirschman Index (HHI), CRn concentration index and other ratios. At the same time, in the conditions of continuing consolidation of the banking system via mergers and acquisitions and a decreasing number of banks, upward trends are observed within moderate, average European levels. Therefore, these new conditions require closer attention on the part of banking regulators to assess possible consequences of concentration. This article provides recommendations to the National Bank of Ukraine (NBU) and the Antimonopoly Committee of Ukraine (AMCU) on how to improve monitoring of banking concentration processes and better regulate consolidation processes in bank mergers and acquisitions. A complex of preventive macroprudential measures was offered to offset the negative consequences of concentration and achieve an optimal degree of market consolidation.
THE EFFECT OF ENVIRONMENTAL PERFORMANCE ON FIRM’S PERFORMANCE – EVIDENCE FROM GHANA

ABSTRACT This paper looks at the effect of environmental performance on firm’s performance of mining companies in Ghana. The study looked at total cash cost and capital expenditure as measures of firm’s performance of selected mining company. The study used recent econometric approach: Fully Modified Ordinary Least Square (FMOLS) to find the long run relationship between the environmental performances and firm’s performance. The approach of the study is case study of a selected mining company listed at Ghana Stock Exchange for the study period 2007-2015. The study findings are that water consumption has a negative and significant impact on the financial performance of mining companies in Ghana. Hence, our study concludes that companies make environmental performance disclosures as means of meeting industrial regulations and policies and also to make the community see that they are doing something to mitigate the negative effect of their activities in the community.
Substantially Higher and Earlier Occurrence of Anti‐Tuberculosis Drug‐Related Adverse Reactions in HIV Coinfected Tuberculosis Patients: A Matched‐Cohort Study

Abstract Little information exists on the frequency, severity, and timing of first‐line anti‐tuberculosis drug‐related adverse events (TB‐AEs) in HIV‐tuberculosis coinfected (HIV‐TB) patients in the antiretroviral therapy (ART) era. This matched‐cohort study included HIV‐TB patients as cases and HIV‐uninfected tuberculosis (non‐HIV‐TB) patients as controls. Tuberculosis was culture‐confirmed in both groups. Cases were matched to controls in a 1:4 ratio on age, sex, and year of diagnosis. TB‐AEs were defined as Grade 2 or higher requiring drug discontinuation/regimen change. From 2003 to 2015, 94 cases and 376 controls were analyzed (95% men, 98% Asians). Standard four‐drug combination therapy was initiated in 91% of cases and 89% of controls (p = 0.45). Cases had a higher frequency of TB‐AE [51% (48/94) vs. 10% (39/376), p < 0.001]. Their major TB‐AEs were fever (19%), rash (11%), and neutropenia (11%). TB‐AEs were more severe in cases [Grade 3 or higher: cases (71%, 34/48) vs. controls (49%, 19/39), p < 0.001]. The time from treatment initiation to TB‐AE was shorter in cases [median 18 (interquartile range 12‐28) vs. 27 (15‐57) days, p = 0.027], and 73% of TB‐AEs in cases occurred within 4 weeks of starting anti‐tuberculosis treatment. HIV infection was an independent risk factor for TB‐AEs in the multivariate Cox analysis [adjusted HR (aHR): 6.96; 95% confidence interval: 3.93‐12.3]. TB‐AEs occurred more frequently in HIV‐TB than in non‐HIV‐TB patients, and were more severe. The majority of TB‐AEs occurred within 4 weeks of initiating anti‐tuberculosis treatment. Because TB‐AEs may delay ART initiation, careful monitoring during this period is warranted in coinfected patients.

Implementation of Values on Family Company Succession in Bali Province, Indonesia

The main purpose of the research is to investigate the implementation of values on family company successions in Bali. This descriptive research was conducted in family business in Bali which have done successions to, at least, their second generation. The data was analyzed qualitatively and quantitatively by using Likert scale. Meanwhile, to discover the implementation of values towards successors' performance, PLS (Partial Least Square) analysis was carried out. The research elaborates that (1) values are positive and significant effect on the characteristics of successor, (2) values did not affect the succession planning, (3) strong values which were emphasized by the owners did not affect the succession planning, (4) values did not affect the successors' performance, and (5) values which were transferred by predecessors did not have any impacts on the successors' performance. The strongest indicator of values to enhance the performance of successors was innovation.
Actual and intended growth in family firms and non-family-owned firms: are they different?

Purpose Drawing on the motivation theory and family business literature, the purpose of this paper is to investigate the influence of family effect in growth behaviour of small-and-medium-sized enterprises (SMEs) in the UK. Design/methodology/approach The authors first compare the actual and expected growth of family and non-family-owned SMEs. The authors then compare the growth behaviour of small family firms managed by owner-directors and small family businesses co-managed by family and non-family directors with the non-family-owned SMEs. Findings The authors find a negative effect of family ownership on actual and intended small business growth behaviours. In addition, the findings also suggest that small family firms co-managed by non-family and family directors are no different from non-family-owned firms, in terms of reporting past actual growth in employment size and turnover as well as expecting growth in workforce size and turnover. The authors also observe a significant difference in anticipating sales growth between family-controlled and non-family-controlled firms. However, this difference is not explained by the heterogeneity of a top management team. Practical implications The study has important implications for managerial practice to family firms and on policies that improve the growth of SMEs. Specifically, the competence of managers and decision makers matters considerably in evaluating the efficient operation of the business and maximising the economic growth in SMEs. Originality/value The study makes two important theoretical contributions to small business growth literature. First, the findings underline a negative family effect in the actual and expected growth behaviour of SMEs. Second, the mode of family ownership alone may not sufficiently capture family effect and offer a thorough understanding of growth behaviour in SMEs.
Cell salvage and donor blood transfusion during cesarean section: A pragmatic, multicentre randomised controlled trial (SALVO)

Background Excessive haemorrhage at cesarean section requires donor (allogeneic) blood transfusion. Cell salvage may reduce this requirement. Methods and findings We conducted a pragmatic randomised controlled trial (at 26 obstetric units; participants recruited from 4 June 2013 to 17 April 2016) of routine cell salvage use (intervention) versus current standard of care without routine salvage use (control) in cesarean section among women at risk of haemorrhage. Randomisation was stratified, using random permuted blocks of variable sizes. In an intention-to-treat analysis, we used multivariable models, adjusting for stratification variables and prognostic factors identified a priori, to compare rates of donor blood transfusion (primary outcome) and fetomaternal haemorrhage ≥2 ml in RhD-negative women with RhD-positive babies (a secondary outcome) between groups. Among 3,028 women randomised (2,990 analysed), 95.6% of 1,498 assigned to intervention had cell salvage deployed (50.8% had salvaged blood returned; mean 259.9 ml) versus 3.9% of 1,492 assigned to control. Donor blood transfusion rate was 3.5% in the control group versus 2.5% in the intervention group (adjusted odds ratio [OR] 0.65, 95% confidence interval [CI] 0.42 to 1.01, p = 0.056; adjusted risk difference −1.03, 95% CI −2.13 to 0.06). In a planned subgroup analysis, the transfusion rate was 4.6% in women assigned to control versus 3.0% in the intervention group among emergency cesareans (adjusted OR 0.58, 95% CI 0.34 to 0.99), whereas it was 2.2% versus 1.8% among elective cesareans (adjusted OR 0.83, 95% CI 0.38 to 1.83) (interaction p = 0.46). No case of amniotic fluid embolism was observed. The rate of fetomaternal haemorrhage was higher with the intervention (10.5% in the control group versus 25.6% in the intervention group, adjusted OR 5.63, 95% CI 1.43 to 22.14, p = 0.013). We are unable to comment on long-term antibody sensitisation effects. Conclusions The overall reduction observed in donor blood transfusion associated with the routine use of cell salvage during cesarean section was not statistically significant. Trial registration This trial was prospectively registered on ISRCTN as trial number 66118656 and can be viewed on http://www.isrctn. com/ISRCTN66118656.
Centralized Volt–Var Optimization Strategy Considering Malicious Attack on Distributed Energy Resources Control

The adoption of information and communication technology based centralized volt–var control (VVC) leads to an optimal operation of a distribution feeder. However, it also poses a challenge that an adversary can tamper with the metered data and, thus, can render the VVC action ineffective. Distribution system state estimation (DSSE) acts as a backbone of centralized VVC. Distributed energy resources (DER) injection measurements constitute leverage measurements from a DSSE point of view. This paper proposes two solutions as a volt–var optimization DSSE malicious attack mitigating strategy when the DER injection measurements are compromised. The first solution is based on local voltage regulation controller set-points. The other solution effectively employs historical data or forecast information. The concept is based on a cumulant-based probabilistic optimal power flow with the objective of minimizing the expectation of total power losses. The effectiveness of the approach is performed on the 95-bus U.K. generic distribution system and validated against Monte Carlo simulations.
