Effect of addition ZrO 2-Al 2 O 3 nanoparticles mixture on some properties and denture base adaptation of heat cured acrylic resin denture base material

Background: The PMMA polymer denture base materials are low mechanical properties, adaptation of the denture base to underlying tissue is important for retention and stability of denture. The aim of the study was toevaluate the effect of mixtureZrO2-Al2O3 nanoparticles on impact strength, transverse strength, hardness, roughness, denture base adaptation of heat cured acrylic resin denture base material. Materials and methods: One hundred (100) specimens were prepared, the specimens were divided into five groups (20 specimens to each) according to the test type, each group was subdivided in to two subgroups (control and experimental) each subgroup consist of 10 specimens, the experimental group included mixture of 2% (ZrO2Al2O3ratio2:1) by weight. Theimpact strength was measured by Charpy's impact testing machine, the transverse strength was measured by Instron testing machine while the hardness was measured byshore D durometer and roughness was measured by Profilometer. Denture base adaptation was measured by digital microscope and evaluated by computerized tomography (CT). Results: Highly significant increaseofimpact and transverse strength, non-significant increase ofhardness, significant increase ofroughness andreduction of denture base adaptation (measured at 3 point A, B and C) occurred in experimental groupwhen compared to control group. CT evaluation, gap between the denture base and master cast (control and experimental groups) increased from the anterior to posterior side of palate and from the alveolar ridge to the mid palatal line. Conclusion: The polymer nanocomposites had mechanical properties higher than neat PMMA at same time less denture base adaptation.
Critical Factors for Diffusion of Web Technologies for Supply Chain Management Functions: Malaysian Perspective

Good supply chain management is essential for a successful company. Supply chain management can reach beyond the boundaries of a single company to share that information between suppliers, manufacturers, distributors, and retailers. This is where the information technologies play an important role. Information technology (IT) facilitates companies to share of large amounts of information along the supply chain, and is often referred to as vital facilitator of supply chain management (SCM) functions. As a new medium of communication, the Internet has conquered the world with break taking speed, and it’s the worldwide penetration and high level of standardization contributes to increase globalization. With new web technologies, Internet based systems can deliver functionality and information to user a standard web browser, thereby eliminating requirement for traditional Electronic Data Interchange (EDI) or client based software and reducing information technology implementation and maintenance costs, cycles and burdens. The Internet offers the supply chain immense potential and entirely new ways for streamlining coordination between business partners and customers. Therefore, this study explores the use of use technologies for organizational SCM. Based on an extensive survey of Malaysian organizations, it investigates the diffusion of web technologies into supply chain functions. The findings suggested that top management support and Trialability play crucial role for diffusing web technologies in supply chain. This study provides a greater understanding of managers’ perception of web technologies diffusion in their organizations. Those interested in adopting web technologies in their supply chain activates may find these results helpful in guiding their effort.
Impact of Nurse-Led Telephone Follow-up on Heart Failure Readmissions

Heart failure readmissions are a common and costly issue. Poor transitions of care as patients move from one setting to another are thought to be a major contributor to this growing problem. For those patients discharged to skilled nursing facilities (SNFs), poor transitions can be especially problematic. Telephone follow-up by nurses is a cost effective intervention commonly used to improve communication and coordination of care, thought little is known about interventions directed at patients discharged to SNFs. The purpose of this review is to evaluate the evidence regarding nurse led telephone follow-up in the transition of care process and provide a foundation for future study of these interventions in the SNF population. Synthesis of evidence from an integrative review, four systematic reviews, and three clinical practice guidelines suggests telephone follow-up may aid in the reduction of readmissions but further study is needed to determine the most effective structure of a telephonic program.

The Use of a Medical Device Surrogate for Cooperative Product Development Learning of Engineering Design

Jeffrey T La Belle is currently an Assistant Professor in the School of Biological Health and Systems Engineering and the Biodesign Institute at Arizona State University. He holds adjunct status in the School of Energy and Matter Transport (Mechanical Engineering) as well as the College of Medicine at Mayo Clinic. He has a Ph.D. and Masters in Biomedical Engineering from ASU and a MS and BS in Electrical Engineering from Western New England University in Springfield Massachusetts. In the La Belle Group, we are currently developing electrochemical sensors for noninvasive glucose sensing, the novelty of our design is to obtain tear fluid for tear to blood glucose correlation in a noninvasive means to increase patient compliance. The next leap in technology for diabetes care is a multiplexed sensor that will add more depth of information for a self-monitoring blood glucose devices, here five accepted markers for DM care and management, including glucose, HbA1c, among others are simultaneously monitored on a single strip sensor. This technology we are developing could also allow for continuous and single use stress/trauma sensing technologies. Other applications of the sensing technologies include small molecule, DNA, protein, and whole cell detection to address changing climate in point-of-care technologies and medicine. On the activation side of our research, we are fabricating nitinol staggered muscle arrays that mimic skeletal muscle and we have recently demonstrated over 30% compression in our SMA’s similar to muscle bundles. Our approach to design is simple, following FDA guidelines and suggestions from the start, look at what the user needs and/or wants and apply a unique solution. We have a well-diversified group to tackle the challenges in health care today, staff and students come from biomedical engineering, electrical engineering, mechanical engineering, chemical engineering, computer science engineering, as well as biology and chemistry programs at ASU. BME at ASU teaches a 8 semester wide medical device design tract that initiates the students in design, regulations, standards, IP and other aspects from day 1. Dr. La Belle has develop and courses and taught at the freshman, junior, senior and graduate level on these topics.
Shift in seagrass food web structure over decades is linked to overfishing

Empirical field studies in seagrass have revealed that overgrowth by filamentous algae which reduces seagrass growth can be explained by a top-down cascading effect caused by declines in top predators, which is enforced by eutrophication. On the Swedish west coast, 60% of the seagrass has disappeared since the 1980s. We hypothesised that overfishing, responsible for a > 90% decline in the cod stock, and the 4 to 8 times increase in nutrient load since the 1930s have altered the seagrass structure and function during recent decades. We used quantitative samples from the 1980s and 2000s and analysed the trends in abundance of the 4 feeding guilds: top predatory fish, intermediate predatory fish, crustacean omnivores and mesoherbivores. Since the 1980s, the commercial catch of gadoids on the Swedish west coast has decreased by >90%, and here we found that the biomass of top predators (gadoids and trout) that forage in seagrass has decreased by approximately 80%. In contrast, the biomass of intermediate predatory fish (gobids and sticklebacks) has increased 8 times during summer and 11 times during autumn, while meso- herbivores (idoteids and gammarids > 7 mm) have more or less disappeared from the seagrass bed. We thus found clear evidence that a shift in seagrass food web structure has taken place over the last 3 decades. Combining these findings with our recent empirical results from field cage exper- iments in the Skagerrak seagrass, where we manipulate top-down and bottom-up regulation, we conclude that lack of grazers in concert with eutrophication most likely contributed to the over- growth by filamentous algae and disappearance of the seagrass on the Swedish west coast.
Rearing of Burbot, Lota lota (Pisces, Teleostei), Larvae with Zooplankton and Formulated Microdiets

Different feeding methods were tested for burbot, Lota lota, larvae. In small scale experiments with 300 larvae per treatment grinded artemia flakes, enriched artemia flakes, artemia flakes supplemented with dried algae (Chlorella sp., Spirulina sp.) and formulated microdiets consisting of different combinations of fishmeal, fish oil, soybean lecithin, casein, dextran, and artemia flakes were fed over a period of 30 days. These foods were compared to live zooplankton food collected from the nature. After 30 days, only feeding with live zooplankton resulted in high survival rates > 80%. No survival was observed with artificial microdiets. The 15 d survival of larvae was significantly lowest with agar agar bound microparticles and with formulated diets containing > 7% soya lecithin and > 3 % fish oil. The live zooplankton feeding method was also tested in a large scale experiment with 25,000 larvae per tank for a period of 100 d. After 100 d the larvae survival rate was > 65 %, and the body length had increased for circa 6-fold.

Factors determining failure of intertrochanteric fracture fixation with a dynamic hip screw: a retrospective analysis

Background: The intertrochanteric fractures are extra capsular fractures of proximal femur in the trochanteric region. Different fixation techniques were tried for intertrochanteric fractures, with variety of implants but the dynamic hip screw fixation is most widely accepted treatment. However, several authors have concluded that sliding compression screws may be associated with several complications such as perforation of the femoral head, loss of reduction caused by excessive sliding of the lag screw, non-union, shortening of the affected limb and pain. This study was carried out to ascertain the factors that contributed to mechanical failure at our institute.Methods: We retrospectively reviewed 92 patients with unilateral intertrochanteric fracture treated with a sliding hip screw between July 2015 and April 2017. Postoperative radiographs were studied for any loss of reduction, which was defined as a varus deformity greater than 10°, perforation of the femoral head, extrusion of the lag screw of more than 20 mm, or metal failure. The Pearson chi-square test was used to assess the relationship between failure and osteoporosis. A p value of less than 0.05 was considered to be significant.Results: Results revealed a significant relationship between failure and osteoporosis. A possible relationship between the stability of the fracture on Evans’ classification and osteoporosis on Singh’s index was investigated which revealed a high positive correlation between the failure rates of unstable fractures with osteoporosis.Conclusions: An unstable fracture combined with osteoporosis, has higher percentage of fixation failure leading to other methods of treatment like hemiarthroplasty.
Traveling water waves along quartic bottom profile

The problem of transmission of wave energy in strongly inhomogeneous media is discussed with application to long water waves propagating in a basin with a quartic bottom profile. Using the linear shallow-water theory it is shown that the wave component of the flow disturbance is described by a travelling wave solution with an amplitude and phase that vary with distance. This means that the kinetic part of the wave energy propagates over large distances without reflection. Conditions for wave breaking in the nearshore are found from the asymptotic solution of the nonlinear shallow-water theory. Wave runup on a vertical wall is also studied for a quartic bottom profile.
CATCH ME IF YOU LEARN: DEVELOPMENT-SPECIFIC EDUCATION AND ECONOMIC GROWTH

This paper presents a theoretical and empirical investigation of the relationship between human capital composition and economic growth. In the theoretical analysis, we allow for nonconstant returns to scale in technological activities. Differently from previous literature, our results show that, under broad and plausible model parameterizations, the marginal growth effect of skilled workers is increasing with the distance to the frontier for sufficiently poor countries while it is decreasing (in agreement with the existing literature) only for countries close to the technological frontier. Our empirical analysis provides robust evidence for this theoretical prediction by using a 10-year panel of 85 countries for the years in between 1960 and 2000, as well as by using the System Generalized Methods of Moments (GMM) technique to address the problem of endogeneity. Results are robust to different proxies of human capital and different specifications.
Problems related to the taxonomic placement of incompletely preserved amber fossils: transfer of the Paleogene liverwort Cylindrocolea dimorpha (Cephaloziellaceae) to the extant Odontoschisma sect. Iwatsukia (Cephaloziaceae)

Abstract. A revision of the Baltic and Bitterfeld amber fossils assigned to Cylindrocolea dimorpha (Cephaloziellaceae) has yielded evidence of the presence of multicellular, bifid underleaves, which have not previously been reported for this species and conflict with the current circumscription of the family. We transfer the fossil species to Odontoschisma (sect. Iwatsukia) and propose the new combination O. dimorpha of the Cephaloziaceae. Characteristics of the fossil include an overall small size of the plant, entire-margined, bifid leaves and underleaves, more or less equally thickened leaf cell walls, ventral branching that includes stoloniform branches with reduced leaves, and the lack of a stem hyalodermis and gemmae. Placement of the fossil in Cephaloziaceae profoundly affects divergence time estimates for liverworts based on DNA sequence variation with integrated information from the fossil record. Our reclassification concurs with hypotheses on the divergence times of Cephaloziaceae derived from DNA sequence data that provide evidence of a late Early Cretaceous to early Eocene age of the Odontoschisma crown group and an origin of O. sect. Iwatsukia in the Late Cretaceous to Oligocene.
Linguistic practices in Cyprus and the emergence of Cypriot Standard Greek

In Cyprus today systematic changes affecting all levels of linguistic analysis are observed in the use of Standard Greek, giving rise to a distinct linguistic variety which can be called Cypriot Standard Greek. The changes can be attributed to the influence of English and Cypriot Greek (the local linguistic variety), and to the increasing use of the Standard in semi-formal occasions. Equally important is the reluctance to recognize the diglossic situation on the island (in which Standard Greek is the H variety and Cypriot Greek the L), for political and ideological reasons. This in turn means that the attention of the Cypriot speakers is not drawn to the differences between Standard Greek as spoken in Greece and their usage of it; thus the differences become gradually consolidated, while the users remain unaware of them.
Food plants in home gardens of the Middle Magdalena basin of Colombia

Home gardens are important reservoirs of agricultural diversity essential to support food security in rural communities. In this paper, we describe the richness and composition of species and varieties of plants used for food in home gardens of the municipality of San Pablo in the Middle Magdalena Basin of Colombia, and discuss its possible relations with a set of socio-economic and structural variables. A survey was conducted in 20 home gardens where semi structured questionnaires were administered to the head of each household, and all plants used as food were recorded. The physical characteristics of the home gardens varied widely. Farmers’ ages varied between 28-90 years and the most frequent level of schooling was primary education. In total, 75 species represented by 162 varieties were found. Plantains ( Musa x paradisiaca ), mangos ( Mangifera indica ), guavas ( Psidium guajava ) and cassavas ( Manihot esculenta ) were the most diverse and frequent crops across gardens. The mean number of species per home garden was 17.5 (SD = 7.1), ranging from 6 to 33. On average 48% of the species recorded were fruits, followed by spices (17%), roots and tubers (12%) and vegetables (9%). Significant correlations were found between food plant richness and farmers’ ages ( r s = 0.461, p = 0.04) and food plant richness and number of family members ( r s = -0.487, p = 0.03). Home gardens of San Pablo are important regional agrobiodiversity reservoirs that support families’ nutrition.
From Material Level to Structural Use of Mineral-Based Composites—An Overview

This paper surveys different material combinations and applications in the field of mineral-based strengthening of concrete structures. Focus is placed on mechanical behaviour on material and component levels in different cementitious composites; with the intention of systematically maping the applicable materials and material combinations for mineral-based strengthening. A comprehensive description of a particular strengthening system developed in Sweden and Denmark, denominated as Mineral-based Composites (MBCs), together with tests from composite material properties to structural elements is given. From tests and survey it can be concluded that the use of mineral-based strengthening system can be effectively used to increase the load bearing capacity of the strengthened structure. The paper concludes with suggestions on further development in the field of mineral-based strengthening.
Validation of a whole blood serology test for diagnosing helicobacter pylori in Chinese patients

VALIDATION OF A WHOLE BLOOD SEROLOGY TEST FOR DIAGNOSING HELICOBACTER PYLORI IN CHINESE PATIENTS. Matthew S. Falk and Joseph J. Y. Sung. Department of Medicine and Therapeutics, Prince of Wales Hospital, Chinese University of Hong Kong, Shatin, Hong Kong. (Sponsored by Matthew E. Cohen, Department of Internal Medicine, Yale University School of Medicine). Purpose To assess the accuracy of the FlexPack HP (Abbott Laboratory), a rapid whole blood mimunochromatographic serology test, for diagnosing Helicobacter pylori infection in Hong Kong Chinese patients. Methods Consecutive patients with dyspepsia presenting for endoscopic examination were recruited for FlexPack HP testing. Those having received previous anti-// pylori therapy or those currently taking antibiotics or acid-suppressive drugs were excluded. In addition to having the FlexPack HP test, all patients were tested for H. pylori using histology, rapid urease test and a [13C] urea breath test. Patients were considered to be infected with H. pylori when two or more of these three reference tests were positive. Results One hundred patients were studied. The average age was 51 +/15 years (range 21-90 years), 55% of whom were female. Endoscopy revealed gastric ulcers in 5%, duodenal ulcers in 6%, gastric erosions in 7%, gastric erythema in 20% and no apparent disease in 62%. Fifty-four (54%) of the patients had H. pylori infection based on study definitions. FlexPack HP test characteristics were: sensitivity 82% (95% CI: 73 88%), specificity 85% (95% CL 74 92%), positive predictive value 86% (95% CI: 77 93%) and negative predictive value 80% (95% CI: 70 86%). A faint line, interpreted as positive, was seen in 15 (15%) of the FlexPack HP results. No invalid tests occurred as assessed by the control panel integral to the FlexPack HP test. Conclusion FlexPack HP was quick, convenient and accurate when used in a secondary care setting in Hong Kong Chinese patients. This test may be useful for in-office H. pylori testing. Table of
Spore morphology of Selaginella (Selaginellaceae) from China and its systematic significance

Using light microscope (LM) and scanning electron microscope (SEM), the megaspores and microspores of 77 samples representing ca. 70 species of Selaginella from China are observed. Combing previous studies, the spore morphology of nearly all documented Selaginella species from China were reviewed. Based on the morphological characteristics in megaspores and/or microspores, we divided the spores of Chinese species into 15 types and three types are further divided into various subtypes. Each type and subtype are described in detail and a key to the types and subtypes of spores is given. For the first time, the systematic significance of microspores of Selaginella are discussed, and the results indicate that microspores of Selaginella are significant in the systematics of Selaginella . Some important morphological characteristics in spores (e.g., color, micro-sculpture, size, etc.), often been neglected in previous studies, are introduced. Some spore-morphological synapomorphies of the clades and subclades, identified by recent molecular work (Zhou et al. 2015a), are well established. Using the spore morphology, the delimitation of some taxonomically difficult species in Selaginella is assessed.
Candidate genes in the field of exercise genomics

Skeletal muscle is extremely adaptable to various stresses which can be placed upon it. In spite of importance of skeletal muscles, little is known about genetic factors which demonstrate high influence to muscle size, function, strength and adaptation to various environmental factors. Because endurance performance is a multifactorial trait, the list of candidate genes which could account for human variation in related phenotypes is extensive. One of the first characterized and most frequently studied genetic variant is a polymorphism in the angiotensin converting enzyme I gene. The ACTN3 gene is the first structural skeletal muscle gene with a relation between its genotype and elite sprinter’ performance. Nevertheless, current genetic testing cannot provide an extra advantage over existing testing methods in determining sports selection in young athletes. The main challenge still remains to identify other, complex polygenetic variants and their interactions with environmental factors which could provide benefit in the sports selection and existing talent identification.
