Stress-based non intrusive shape optimization for additive manufacturing parts

We live in a time where resources are scarce and tools are developed to control their use. One of the most powerful material-saving tools is shape optimization. This latter is a computational method in which the shape of a designed part is adapted by adding or removing material according to the environment in which this part will be used. This method produces complex shapes, difficult to manufacture using classical techniques. In such situations, additive manufacturing appears to be as an appealing approach. In this paper, a non intrusive average stress based shape optimization technique is presented. This technique is composed of a processing phase followed by a post processing smoothing phase. In the processing phase, the stresses in a certain part are calculated using finite elements analysis. Then the Von mises effective stresses are calculated and compared to the average stress in the part. The low stress elements are removed, and hence in each iteration the average stress is changing as well as the standards deviation. After several iterations, the algorithm converges and the part is ready for the post processing phase. In the next phase, the part has non smooth surface because of the element removal. Each node on the non smooth surface is detected and the concavity of the surface to which it belongs is found with respect to the topology of its environment, using a weighted Laplacian algorithm linking the selected node to its neighbors. The obtained concavity is then applied to each node. The process is repeated for several iterations until the surface is smooth as desired and the final shape is found and ready for printing. This technique has been tested on several load configurations and the obtained results were in agreement with other techniques from the open literature [1]. This method is attractive since it doesn’t need to re-mesh the domain at every iteration. In addition, it does not require a high processing power since the results were obtained during half an hour using a medium fine mesh on an i5 processor with a home made code. Furthermore, at the end of this algorithm the stress distribution in the part is quasi-homogeneous and it gives flexibility for the user to choose the desired stress criterion which suitable for the studied application.

Testing of Fama and French Factors in Indian Capital Market

We tests whether Fama and French factors explain the portfolio returns as envisaged in Fama and French (1995). We use National Stock Exchange continuously traded stocks, Nifty Index and other relevant data from July 1996 to June 2010. We have formed portfolios based on size and value which are regressed over factors portfolios-market, size and value. The results show that portfolio returns are not explained by factors portfolios with the exception of big stocks portfolios are explained to some extent. Further results show that portfolio returns of small stocks are not explained by factor portfolios.
High-Frequency Mapping of the IPv6 Internet Using Yarrp

Both the number of hosts using Internet Protocol version 6 (IPv6), and the volume of IPv6 traffic, has increased exponentially since 2012. With this adoption, the IPv6 routed infrastructure becomes an increasingly important component of global critical infrastructure and network policy. Unfortunately, the tools and techniques used to perform active network topology discovery were designed for Internet Protocol version 4 (IPv4), leading to a potentially opaque view of the IPv6 Internet. In this thesis, we extend nascent work on stateless high-speed IPv4 active topology probing to develop a new IPv6 traceroute method “Yelling At Random Routers Progressively version 6” (Yarrp6). Yarrp6 randomly permutes the set of IPv6 targets and hop counts to distribute load, thereby helping to avoid IPv6 response rate limiting. Further, we encode state in the IPv6 payload to permit Yarrp6 to both match responses with probes and use different probe transport protocols. Via active experimentation on the public IPv6 Internet, we compare the results obtained from Yarrp6 against the current state-of-the-art IPv6 topology mapping tool. We show that Yarrp6 can discover topology at more than an order of magnitude faster than previously possible. Finally, we conduct a study of the effect of transport layer protocol on forward Internet Protocol (IP) path inference to determine what protocol is best used for active IPv6 topology discovery.
Molecular allergen profiling of dual mite sensitization in severe allergic rhinitis.

BACKGROUND Mites are the most prevalent source of indoor allergens. The aim of the present study is based on a component resolved diagnosis (CRD) model approach to investigate the mite specific IgE sensitization profile to Dermatophagoides pteronyssinus and Blomia tropicalis and the performance outcomes of commercially available CRDin subjects with severe allergic rhinitis (SAR). METHODS We selected 63 consecutive patients showing a dual sensitization to D. pteronyssinus and B. tropicalis with persistent severe rhinitis according to the ARIA Guidelines. Skin pricktest with standardized extracts and specific serum IgE to both mites along with serum specific IgE to Der p 1, Der p 2, Der p 23, Der p 10 and Blo t 5 was measured. RESULTS Fifty-eight and 59 patients showed a positive sIgE to the whole extracts of D. pteronyssinus and B. tropicalis, respectively. While 91.67% of patients were sensitized to specific IgE Der p 1, Der p 2 and/or Der p 23, specific IgE to Blo t 5 (≥0.3 ISU-E) was not detected in the majority (55%) of the serum samples. CONCLUSIONS Although the combination panel of the commercially available major allergens Der p 1, Der p 2 and Der p 23, identified more than 90% of the D. pteronyssinus allergic patients, Blo t 5 showed a very limited performance in those sensitized to B. tropicalis. Improvements in CRD and further research concerning the prevalence and clinical relevance of serodominant allergens are needed to achieve a genuine molecular diagnosis along with a patient-centred mite-allergy specific immunotherapy.
A review on potential underutilized medicinal fruit plant Bhela ( Semecarpus anacardium L . )

Bhela or bhallatak (Semecarpus anacardium Linn.) has been used for medicinal and non-medicinal purposes since ancient times. The toxicity of bhallatak precludes its mega scale production particularly as a medicine at the industrial level. The properties of this fruit used against various diseases after proper detoxification. However, traditional healers and physicians of Indian systems of medicine continue to use bhallatak in various forms in their clinical practice. Several experimental investigations have been undertaken in diverse in vitro and in vivo models. The major focus of these investigations reported in the current literature regarding on its historical background, botany, general uses with pharmacological activity, poisonous nature, antidotes and propagation to get a better insight and comprehend its narrow therapeutic margin. It is important to understand the significance of Ayurveda inspired investigation of this traditionally acclaimed medicinal plant.

The study points to an improvement of entrepreneurship education through customized offers dependent on the student’s level of EI and entrepreneurial self-efficacy. Originality/value. Moreover, this study has proven that the JCA is a useful method to analyse the relationship between EI and other related variables in an exploratory study.
Validation of the Communication Skills Attitude Scale (CSAS) Questionnaire in a Cohort of Malaysian Medical Students

Introduction: The Communication Skills Attitude Scale (CSAS) assesses medical students’ attitudes towards learning communication skills and had been widely utilised all over the world. This questionnaire has 26 items framed within two subscales. This study aimed to examine the validity and reliability of the CSAS among medical students in Universiti Teknologi MARA (UiTM). Methods: This was a cross sectional questionnaire validation study among 171 first year medical students from UiTM. The CSAS had undergone content and face validation, followed by psychometric analysis using principal component analysis to assess construct validity. Internal consistency was evaluated using Cronbach alpha. Results: Factor analysis confirmed the original two-subscale structure of the CSAS (positive attitude scale, PAS and negative attitude scale, NAS). A total of 4 items were removed due to poor factor loading (1 item from PAS and 3 items from NAS). The final validated CSAS consisted of 22 items, 14 and 8 items for the PAS and NAS respectively. Cronbach alphas calculated were 0.862 for the PAS and 0.565 for the NAS. Conclusion: This study produced a validated and reliable CSAS to measure the attitude of UiTM medical students towards learning communication skills. Given the low internal reliability of the NAS in this study, future studies should include translating and validating the CSAS into the Malay language to improve its psychometric properties. Future studies should also include medical students from the three major ethnic groups and other medical schools in Malaysia to improve the generalisability of the CSAS.
Chapter 12 Genome-Wide Analysis of Yeast Aging

In the past several decades the budding yeast Saccharomyces cerevisiae has emerged as a prominent model for aging research. The creation of a single-gene deletion collection covering the majority of open reading frames in the yeast genome and advances in genomic technologies have opened yeast research to genome-scale screens for a variety of phenotypes. A number of screens have been performed looking for genes that modify secondary age-associated phenotypes such as stress resistance or growth rate. More recently, moderate-throughput methods for measuring replicative life span and high-throughput methods for measuring chronological life span have allowed for the first unbiased screens aimed at directly identifying genes involved in determining yeast longevity. In this chapter we discuss large-scale life span studies performed in yeast and their implications for research related to the basic biology of aging.
Preservation of Right Gastroepiploic Vein to Lessen Left-Sided Portal Hypertension after Conversion Pancreaticoduodenectomy with Concomitant Vascular Resection after Chemotherapy for a Locally Advanced Pancreatic Cancer

More than 30% to 40% of all cases of pancreatic cancer are initially considered unresectable. Unresectable Locally Advanced Pancreatic Cancer (UR-LAPC) patients have a poor prognosis worldwide, and almost all these patients have extensive vascular involvement and perineural invasion at initial diagnosis that precludes surgical intervention. Recently, some reports have revealed that induction chemotherapy followed by conversion surgery for UR-LAPC may be more efficacious. In locally advanced pancreatic head and body cancer, Portal Vein (PV) and Superior Mesenteric Vein (SMV) is frequently involved because of the vein’s anatomical location. In Pancreaticoduodenectomy (PD) combined with vascular resection may cause secondary Left sided Portal Hypertension (LPH). We report a case of successful conversion surgery for an initial UR-LAPC after induction GEM + nab-PTX chemotherapy. In PD with resection of PV, SMV, Splenic Vein (SV), inferior mesenteric vein (IMV) and Left Gastric Vein (LGV) confluence may cause secondary LPH, but concomitant preservation of Right Gastroepiploic Vein (RGEPV) may attenuate secondary LPH.
MODELLING REALITY : THE NEED FOR BOTH INTERTEMPORAL OPTIMIZATION AND STICKINESS IN MODELS FOR POLICY-MAKING

This paper contributes to the ongoing debate on the usefulness of economic models for policy analysis. It argues that there is a need for models which incorporate both the modern inter-temporal approach to macroeconomics and short-run ad-hoc behaviour. This need cannot be met by the simple models that permeate the macroeconomics literature, but requires large-scale simulation models such as the MSG2 and G-Cubed multi-country models. It is shown that these models give insights into the adjustment process in a number of historical episodes which are not well explained by simple macroeconomic frameworks: Reaganomics in the 1980s; German reunification in the early 1990s; fiscal consolidation in Europe in the mid-1990s; the formation of NAFTA; the Asian Crisis; and the current productivity boom in the USA. The paper also argues that using a well-defined theoretical specification but introducing real-world rigidities can also help to explain the ‘six major puzzles in international macroeconomics’ highlighted in a recent paper by Obstfeld and Rogoff (2000).
Biosorption of Cadmium from Aqueous Solution by ULMUS Leaves and their Ash

The biosorption capability of Ulmus leaves and their ash for Cadmium ions removal from aqueous solutions has been investigated as a function of appropriate equilibrium time, concentration of adsorbate and pH using a batch system. The effect of metals such as Ca Mg Na and K on biosorption was studied. Studies showed that equilibrium time to biosorption of Cadmium was 60 minutes, optimum pH was 6 and initial concentration 2mg/Lfor both Ulmus Leaves and their ash respectively. Simultaneous adsorption of Cd (II) and Cr (VI) ions was studied using a medium that contained 2 mg/ L of each metal ion. The effect of these biosorbents on increasing COD in aqueous solution shows that 2g/L biosorbent cause increase 130 and 75 mg/L COD in deionized water at 60 minutes for Ulmus Leaves and their ashrespectively. The Cadmium biosorption obeyed both Longmuir and fraundlich isotherms but lungmuir isotherm was better by R=0.998 for ash and R=0.993 for Ulmus Leaves. The studies showed that Ulmus Leaves ash was more favorable than Ulmus Leaves in removing Cadmium and thus was a better biosorbent.

Trees It ́ s contagious : Calculation and analysis of xylem vulnerability to embolism by a mechanistic approach based on epidemic modeling

Abstract: Vulnerability of xylem to embolism is expressed by vulnerability curves (VC) depicting accumulating loss of hydraulic conductivity (PLC) against mounting pressure stress. VC ́s are obtained experimentally by curve fitting, providing important benchmark data on vulnerability of a species, organ or other specific xylem categories. Since embolism spread by air seeding represents principally an epidemic process, a method based on epidemic modeling is introduced in this contribution which allows rapid and efficient calculation of continuous VC directly from mechanistic equations. The approach is based on the classic SIR model which considers the population to be divided into susceptibles S (functional), infectives I (embolized) and “removed” R individuals (embolized conduits which have exhausted their capacity to pass gas to their neighbors). It is also possible to consider xylem which is composed of different conduit groups (differing in interconnectivity and/or conduit vulnerability). The approach is able to reconstruct all sorts of VC shapes on the basis of two key parameters of embolism, conduit vulnerability and interconnectivity, and the amount of native embolism (initial proportion of I and R conduits). The effect of I and R conduits on VC is different. High initial I leads to non-sigmoidal VC whereas high initial R promotes sigmoidal VC. Heterogeneous conduit populations being composed of conduit groups of different sizes, interconnectivities and conduit vulnerabilities can also lead to non-sigmoidal VC with complex shapes.
EUI Working Papers

This paper studies the welfare effects of international competition in the market for innovations, and analyzes how competition affects the costs and the benefits of cooperative and non-cooperative R&D subsidies. I set up a two-country quality-ladder growth model where the leader, the home country, has R&D firms innovating in all sectors of the economy, and the follower, the foreign country, shows innovating firms only in a subset of industries. The measure of the set of sectors where R&D workers from both countries compete for innovation determines the scale of international Schumpeterian competition. Both governments engage in a strategic R&D subsidy game and respond optimally to changes in competition. For a given level of subsidies, increases in foreign competition raise the quality of goods available (growth effect) and lowers domestic profits (business-stealing effect); the overall effect of competition on domestic welfare depends on the relative strength of these two counteracting forces. When governments play a strategic subsidy game, increases in foreign competition trigger a defensive innovation policy mechanism that raises the optimal domestic R&D subsidy. Cooperation in subsidies leads both countries to set higher subsidies. Finally, while cooperation is beneficial for the global economy, there exists a threshold level of competition below which the home country experiences welfare losses under cooperation.
Drosophila melanogaster protein kinase CK2 interacts with and phosphorylates the neurogenic repressor m8 resulting in the production of a novel eye phenotype

Drosophila melanogaster Protein Kinase CK2 Interacts with and Phosphorylates the Neurogenic Repressor m8 Resulting in the Production of a Novel Eye Phenotype Regina L. Trott Protein kinase CK2 is a serine/threonine protein kinase ubiquitously expressed in eukaryotic organisms. The enzyme is composed of 2 α (catalytic) subunits and 2 β (regulatory) subunits. The minimum consensus site for CK2 phosphorylation is S/TXXD/E, where “X” is any non-basic amino acid. Substrates so far identified include proteins associated with cell cycle regulation and development. In Drosophila melanogaster, the Notch pathway activates members of the Enhancer-of-split Complex [E(spl)-C]. m8, which is a member of the E(spl)-C, was found to interact with and be phosphorylated by CK2. The physiological affects of CK2 phosphorylation were studied in vivo through the Gal4-UAS system. Flies with a reduced eye phenotype were identified in a cross between scaGal4 and the transgenic line m8SD. Two-hybrid analysis indicated m8SD interacted significantly stronger with the proneural bHLH protein Atonal than either m8 or m8SA. These results are the first indication that phosphorylation plays a role in the regulation of E(spl)-C proteins and also the first implication of a role for CK2 during neurogenesis.
Cultural Meaning of Childbearing among Women of a Rural Community in Nigeria

Childbearing generally refers to the normal but complex physiological process that occurs in the lives of mature female species through which offspring are reproduced. This process seems to attract additional meanings in various cultures and these could be of clinical importance. This study aimed to explore the meaning of childbearing among women in a rural community in Nigeria. Phenomenology design was used and data were generated through in-depth personal interviews of twenty-seven childbearing-aged and menopausal women in a rural community in southern Nigeria. Subsequent to thematic data analysis, meanings attached to childbearing emerged which included the following themes: attainment of full womanhood; fulfilment of religious obligation; same sex children means partial fulfilment of parental joy; childbearing strengthens marital relationship; motivation for maternal reward; means of provision of future parental security; inevitable sacrifice as well as childlessness is an unacceptable phenomenon. Conclusion is that although childbearing is a generic physiological process to produce offspring, it connotes other meanings derived from the cultural background of the woman. The findings of this study are of clinical relevance as they provide a clue to provision of culture-sensitive and standard care to women of childbearing age throughout the reproductive cycle.
