Influence of Schneiderian Membrane Perforations on the Prognosis and Outcomes of Lateral Window Sinus Lift Operations: A Retrospective Case Series Study

Introduction: This study analyzed the influence of Schneiderian membrane perforations covered with collagen membranes on the success of augmentation and implantation as well as the influences of smoking, radiation and chemotherapy. Patients and Methods: 182 consecutive operated patients with a total of 298 augmented sinuses and 833 inserted implants were analyzed retrospectively. Success rates of sinus augmentations with perforated and unperforated Schneiderian membranes were compared. Results: Perforations of the Schneiderian membrane occurred in 23.2% (p< 0.001). Success rate decreased from 89.4% (p< 0,001) at unperforated sinuses to 80.0% (p=0.005) at perforated sinuses for the irradiated patients and from 95.6% (p< 0,001) at unperforated sinuses to 89.8% (p< 0.001) at perforated sinuses for patients not treated with radiation therapy. Similar results were found for the implant loss rate, which was highest for perforated sinuses at irradiated patients – 43.9% (p=0.023) – and lowest for unperforated sinuses at not irradiated patients – 4.5% (p< 0.001). Comparing membrane perforation to lost implants and failure rate a statistically significant difference could be detected (p=0,029). Conclusions: Although Schneiderian membrane was covered with collagen membranes in all cases, perforations still have a negative impact on success rates of augmentation and implant survival. Possible improvements of this method should be investigated in following studies. Keywords: Radiation therapy; Smoking; Chemotherapy; Sinus augmentation; Implant loss; Implant survival;
IMPACT OF PERCEIVED DESIRABILITY, PERCEIVED FEASIBILITY AND PERFORMANCE EXPECTANCY ON USE OF IT INNOVATION: TECHNOLOGY ADOPTION DECISIONS AND USE BEHAVIOUR

Theoretical perspectives from the field of entrepreneurship can be used to examine entrepreneurs’ intention to use IT innovations. This study collected 412 completed survey responses from entrepreneurs and used structural equation modelling to test the proposed technology acceptance decision model. The results showed the significant effect of perceived desirability, perceived feasibility and performance expectancy as the salient antecedents of intention to adopt and use IT innovation. This study examined the effect of external factors which prevent or facilitate the adoption and use of new technology. The moderating effect of the propensity to act is examined and the results indicated that when the individual propensity to act is high, taking action becomes more desirable and feasible. This study revealed that, in the current IS environment, individuals adopt and use a new system due to the attractiveness of the system and perceived feasibility, which are derived from intrinsic interest and affective beliefs.

THE CLASSIFICATION AND DISTRIBUTION OF THE SIMULIIDAE ( DIPTERA ) WITH PARTICULAR REFERENCE TO THE GENUS AUSTROSIMULIUM

The affinities and distribution of Austrosimulium Tonnoir are examined in relation to those of other genera in the Simuliidae, especially those represented in the Southern Hemisphere. It is concluded that Austrosimulium is not clearly derivable from or closely related to Gigantodax Enderlein but shows greater affinities with Simulium Latreille. The South American species, A. anthtacinum Bigot is distinctly separated from the Australian and New Zealand species and is doubtfully ascribable to Austrosimulium. The doubtfully disjunctive distribution, the affinities of Austrosimulium with Simulium, and the relationships between the Australian and New Zealand species-groups, suggest that the genus is of northern origin and route of entry into New Zealand, and probably into Australia also.
iDO: Compiler-Directed Failure Atomicity for Nonvolatile Memory

This paper presents iDO, a compiler-directed approach to failure atomicity with nonvolatile memory. Unlike most prior work, which instruments each store of persistent data for redo or undo logging, the iDO compiler identifies idempotent instruction sequences, whose re-execution is guaranteed to be side-effect-free, thereby eliminating the need to log every persistent store. Using an extension of prior work on JUSTDO logging, the compiler then arranges, during recovery from failure, to back up each thread to the beginning of the current idempotent region and re-execute to the end of the current failure-atomic section. This extension transforms JUSTDO logging from a technique of value only on hypothetical future machines with nonvolatile caches into a technique that also significantly outperforms state-of-the art lock-based persistence mechanisms on current hardware during normal execution, while preserving very fast recovery times.

Carbon efficiency in Australian NGER reporting companies: what does the integration tell us?

Despite increasing calls for integration, economic performance and environmental performance, in this case with regard to carbon emissions, are often managed separately in business practice and examined separately in research. This study explores the carbon efficiency (integration of economic and environmental efficiency) of corporations registered under the Australian National Greenhouse and Energy Reporting (NGER) Act 2007. Both carbon emission data and key economic data for Australian NGER reporting companies during 2008-2010 were collected and integrated for the purpose. Economic value generated relative to carbon emissions generated was used as a measure for carbon efficiency. It was found that carbon efficiency results vary significantly between industries and scopes of emissions. Environmentally sensitive industries achieved relatively high efficiency results for Scope 2 carbon dioxide equivalent (CO2-e) emissions, but low efficiency performance for Scope 1 emissions and total energy consumption. A reverse pattern was found in non-environmentally sensitive industries where carbon efficiency outcomes for Scope 1 CO2-e emissions and energy consumption were relatively high but carbon efficiency for Scope 2 emissions was low. The comparison of carbon efficiency results in the 2008-09 and 2009-10 reporting years indicated almost no change in corporate carbon efficiency management since the mandatory disclosure requirements were introduced. While the finding of poor carbon efficiency for direct emissions in environmentally sensitive industries supports current government policies to encourage clean production and fuels, the unexpected poor carbon efficiency for indirect emissions in non-sensitive industries highlights the failure of policies to encourage efficiency improvements in such industries.
Quantum weights of dyons and of instantons with nontrivial holonomy

We calculate exactly functional determinants for quantum oscillations about periodic instantons with a nontrivial value of the Polyakov line at spatial infinity. Hence, we find the weight or the probability with which calorons with nontrivial holonomy occur in the Yang-Mills partition function. The weight depends on the value of the holonomy, the temperature, ${\ensuremath{\Lambda}}_{\mathrm{QCD}},$ and the separation between the BPS monopoles (or dyons) that constitute the periodic instanton. At large separation between constituent dyons, the quantum measure factorizes into a product of individual dyon measures, times a definite interaction energy. We present an argument that at temperatures below a critical one related to ${\ensuremath{\Lambda}}_{\mathrm{QCD}},$ trivial holonomy is unstable, and that calorons ``ionize'' into separate dyons.
The design and use of ‘alternate’ assessments of academic literacy as selection mechanisms in higher education

Abstract In a context where applicants to higher education study vary widely in terms of their prior educational, linguistic and socio-economic backgrounds, it becomes extremely important to assess the extent to which these applicants might be said to be ready to cope with the typical academic reading and writing demands of higher education study. This assessment becomes even more crucial in a country like South Africa, where issues of equity of access, selection and redress remain a central challenge. Put simply, the challenge is to identify academically talented students from educationally diverse backgrounds, especially in cases where the educational backgrounds of these applicants may have militated against them, fully demonstrating their talent in conventional (e.g. school-leaving) examinations. This article describes the theoretical basis for the development of tests of academic literacy that downplay the role of prior learning in the assessment of academic readiness. The uses of these tests as selection mechanisms complementary to conventional academic assessments are also outlined. Empirical data are presented that demonstrate associations between these tests and academic performance in higher education. Issues and challenges regarding the validity and reliability of these tests are presented, and the implications of major research findings on the tests debated and deliberated upon.
Introduced and native herbivores have different effects on plant composition in low productivity ecosystems

QUESTIONS: Understanding how livestock grazing alters plant composition in low productivity environments is critical to managing livestock sustainably alongside native and introduced wild herbivore populations. We asked four questions: (1) does recent livestock and rabbit grazing reduce some plant attributes more strongly than others; (2) does grazing by introduced herbivores (i.e. livestock and rabbits) affect plants more strongly than native herbivores (i.e. kangaroos); (3) do the effects of recent livestock grazing differ from the legacy effects of livestock grazing; and (4) does the probability of occurrence of exotic plants increase with increasing net primary productivity (NPP)? LOCATION: South‐eastern Australia. METHODS: We measured the recent grazing activity of co‐occurring livestock (cattle, sheep, goats), rabbits and kangaroos by counting faecal pellets; historic grazing activity by measuring livestock tracks; and derived NPP from satellite imagery. We used a hierarchical GLMM to simultaneously model the presence or absence (i.e. probability of occurrence) of all plant species as a function of their attributes (growth form, lifespan and origin) to assess their average response to recent grazing, historic grazing and productivity in a broad‐scale regional study. RESULTS: Recent and historic livestock grazing, rabbit grazing and increasing NPP reduced the average probability of occurrence of plant species, although responses varied among plant attributes. Both recent and historic livestock grazing strongly reduced the average probability of occurrence of native species, and forbs and geophytes, but differed in their relative effects on other growth forms. Recent livestock grazing, rabbit grazing and NPP had similar effects, strongly reducing native species and forbs, geophytes, shrubs and sub‐shrubs. The overall effects of recent kangaroo grazing were relatively weak, with no clear trends for any given plant attribute. CONCLUSION: Our results highlight the complex nature of grazing by introduced herbivores compared with native herbivores on different plant attributes. Land managers need to be aware that domestic European livestock, rabbits and other free‐ranging introduced livestock such as goats have detrimental impacts on native plant communities. Our results also show that kangaroo grazing has a relatively benign effect on plant occurrence.
Development of an Occupational Risk Assessment Method; A Case Study of a Research Center in Morocco

: To reduce occupational accidents and diseases, as well as physical and financial losses associated to them, regulations in several countries require risk assessment. However, the difficulty of carrying out the risk assessment was reported by several companies. The present work proposes a method of risk assessment inspired by methods from the literature, and introduces staff competence as a parameter of risk assessment. It also presents the results from a case study of a scientific research center in Morocco. The chemical synthesis laboratory is identified as the laboratory with the highest risk score. Risks related to the handling of chemicals, fire risk and risks related to pressure equipment and fluids are successively risks whose scores are the highest in the whole center and are present in the chemical synthesis lab.
Growth of Cunninghamella elegans UCP 542 and production of chitin and chitosan using yam bean medium

Microbiological processes were used for chitin and chitosan productions by Cunninghamella elegans (UCP 542) grown in a new economic culture medium. The assay was carried out to evaluate the growth of C. elegans using yam bean ( Pachyrhizus erosus L. Urban) medium, in different times of growth (24, 48, 72 and 96 hrs), incubated at 28oC in an orbital shaker at 150 rpm. The lyophilized biomass was determined by gravimetry. The polysaccharides were extracted by alkali-acid treatment, and characterized by infrared spectroscopy, titration and viscosity. C. elegans grown in the yam bean medium and produced higher yields of biomass (24.3 g/ mL) in 96 hrs. The high level was chitosan (66 mg/g), and chitin (440 mg/g) were produced at 48 and 72 hrs of growth, respectively. The polysaccharides showed degree of deacetilation and viscosimetric molecular weight as: 6.2% and 3.25 x10 4 g/mol for chitin, and 85% and 2.72 x 10 4 g/mol for chitosan, respectively. The results obtained suggest high biotechnological potential of yam bean as an economic source to produce chitin and chitosan by C. elegans . In addition, the new medium using yam bean for production of the chitin and chitosan may be used for many purposes to reduce the cost price of fermentation processes.
The BPS domain of Grb 10 inhibits the catalytic activity of the insulin and IGF 1 receptors

Grb7, Grb10 and Grb14 comprise a family of adaptor proteins that interact with numerous receptor tyrosine kinases upon receptor activation. Between the pleckstrin homology (PH) domain and the Src homology 2 (SH2) domain of these proteins is a region of approximately 50 residues known as the BPS (between PH and SH2) domain. Here we show, using purified recombinant proteins, that the BPS domain of Grb10 directly inhibits substrate phosphorylation by the activated tyrosine kinase domains of the insulin receptor and the insulin-like growth factor 1 (IGF1) receptor. Although inhibition by the BPS domain is dependent on tyrosine phosphorylation of the kinase activation loop, peptide competition experiments indicate that the BPS domain does not bind directly to phosphotyrosine. These studies provide a molecular mechanism by which Grb10 functions as a negative regulator of insulinand/or IGF1-mediated signaling. ß 2001 Published by Elsevier Science B.V. on behalf of the Federation of European Biochemical Societies.
Genetic polymorphism of blood proteins in Yugoslav shepherd dog

The present study is aimed to provide the first insight into the genetic constitution of Yugoslav shepherd dog based upon analysis of blood proteins and enzyme polymorphism. A total of 60 Yugoslav shepherd dogs were included in the study and polymorphism of hemoglobin (Hb), acid phosphatase (Acp) superoxide dismutase (Sod), albumin (Al), and transferrine (If) was electrophoretically analysed. Hb system did not show polymorphism. FS and SS phenotypes of Acp were established with Acps allelic gene displaying significantly higher frequency (0.82) than AcpF (0.18). The analysis of Sod polymorphism showed SodAA and SodAB phenotypes controlled by SodA (0.74) and SodB (0.26) with clear predominance of SodA allele. Both Al allelic genes At (0.30) and Als(0.70), and all three possible phenotypes (F, FS, and S) were detected. Seven Tf phenotypes controlled by five allelic genes 77* Tf8, Tf, 77°, and Tf-were revealed which makes the Yugoslav shepherd dog the only dog breed displaying all five Tf genes. The associated gene frequencies were (0.13, 0.35, 0.06, 0.41 i 0.05), respectively. According to the calculated values of homogeneity index, Al and Tf were identified as highly polymorphic protein markers which is a result of importance for future genetic characterization of the Yugoslav shepherd dog. Significant deviations from Hardy-Weinberg equilibrium were detected at Sod and Tf loci these being primarily attributed to genetic drift, although crossbreeding should not be disregarded as a factor of possible importance as well.
PSO BASED DG SIZING FOR IMPROVEMENT OF VOLTAGE STABILITY INDEX IN RADIAL DISTRIBUTION SYSTEMS

Many power system operators and planners are facing serious challenges as DG penetration increases into the distribution networks. The situation is even more critical if the DG is not properly sited as such can lead to an increased power losses and instability of the network. Most objectives have centered on minimization of only real power loss for the system. In this paper optimal sizing of DG considers not only the losses but also voltage stability index value (VSI) so that voltage stability of the network is improved as well. The study also takes into account all the necessary constraints. The objective functions are handled as single multi-objective function, and was subsequently optimized using the proposed Particle swarm optimization (PSO) algorithm. The effectiveness of the algorithm was tested on IEEE 33-Bus test system and result obtained shows that the proposed method gives better DGs outputs and use of VSI values in the optimization has greatly improved the minimum VSI values of the network when compared to situation without it and the power losses did not increase appreciably. The study has also indicated that optimal DG placement has greatly improved voltage profile and voltage stability of the network as well.
Probiotics: History and Evolution

Probiotics are viable microbial species, which are ingested for the purpose of altering the gastrointestinal flora in a manner, which confers health benefits. Currently available probiotic products include a wide array of bacterial and fungal species which are consumed in a variety of preparations. The use of microbials originated (unintentionally) centuries ago when people first noted the beneficial health effects of eating fermented foods. Modern probiotic-containing foods and products are the direct derivatives of these early fermented foods. The use of fermented milk and yogurt are the part of human history and their role has been with humanity, to date, between legends and historical data [1]. The present review outlines the origins of probioticcontaining foods and our subsequent refinement of these biologic agents.
What Do Global Metrics Tell Us about the World?

There are now a wide variety of global indicators that measure different economic, political and social attributes of countries in the world. This paper seeks to answer two questions. First, what is the degree of overlap between these different measures? Are they, in fact, measuring the same underlying dimension? To answer this question, we employ a principal component analysis (PCA) to 15 indices across 145 countries. The results demonstrate that there is one underlying dimension that combines economic development and social progress with state stability. Second, how do countries score on this dimension? The results of the PCA allow us to produce categorical divisions of the world. The threefold division identifies a world composed of what we describe and map as rich, poor and middle countries. A five-group classification provided a more nuanced categorization described as: The very rich, free and stable; affluent and free; upper middle; lower middle; poor and not free.
Evolution of galaxy size–stellar mass relation from the Kilo-Degree Survey

We have obtained structural parameters of about 340,000 galaxies from the Kilo Degree Survey (KiDS) in 153 square degrees of data release 1, 2 and 3. We have performed a seeing convolved 2D single S\'ersic fit to the galaxy images in the 4 photometric bands (u, g, r, i) observed by KiDS, by selecting high signal-to-noise ratio (S/N > 50) systems in every bands. We have classified galaxies as spheroids and disc-dominated by combining their spectral energy distribution properties and their S\'ersic index. Using photometric redshifts derived from a machine learning technique, we have determined the evolution of the effective radius, \Re\ and stellar mass, \mst, versus redshift, for both mass complete samples of spheroids and disc-dominated galaxies up to z ~ 0.6. Our results show a significant evolution of the structural quantities at intermediate redshift for the massive spheroids ($\mbox{Log}\ M_*/M_\odot>11$, Chabrier IMF), while almost no evolution has found for less massive ones ($\mbox{Log}\ M_*/M_\odot <11$). On the other hand, disc dominated systems show a milder evolution in the less massive systems ($\mbox{Log}\ M_*/M_\odot <11$) and possibly no evolution of the more massive systems. These trends are generally consistent with predictions from hydrodynamical simulations and independent datasets out to redshift z ~ 0.6, although in some cases the scatter of the data is large to drive final conclusions. These results, based on 1/10 of the expected KiDS area, reinforce precedent finding based on smaller statistical samples and show the route toward more accurate results, expected with the the next survey releases.
STUDENTS' PERCEPTIONS OF MATHEMATICS CLASSROOM ENVIRONMENT AND MATHEMATICS ACHIEVEMENT: A STUDY IN SIPITANG, SABAH, MALAYSIA.

Mathematics classroom environment and mathematics achievement are some of the important mathematical constructs in teaching and learning of Mathematics in the classroom. This study compared such constructs between genders of schools students in Sipitang, Sabah. This study also focused on determining the relationship between these two constructs. All the secondary schools with sample sizes of 235 were selected to participate in this study. Two research instruments were used in this study. A 76-item mathematics classroom environment questionnaire based on “What is Happening in This Classroom” (WIHIS) and the Constructivist Learning Environment Survey (CLES) were used to determine the mathematics classroom environment. The students’ mathematics achievement was determined using a test comprising of 20 multiple choice questions and 5 subjective questions based on the first five chapters in Mathematics Form 4 syllabus. Data from the study was analyzed with SPSS 17.0 using both descriptive and inferential statistical analyses. Findings showed the students had a moderate perception of their mathematics classroom environment. Mathematics achievement was low, with female students achieving better than males in their mathematics assessment. There was no significant difference in perception of mathematic learning environment based on gender. Significant of weak correlations were found between mathematics classroom learning Environment and mathematics achievement. The research findings bring some meaningful implications to the teaching and learning of mathematics at secondary school as well as the training of mathematics teachers in Malaysia.
