Authors: SoutoMaior JR , de Moraes SLD , Lemos CAA , Vasconcelos BC do E , Montes MAJR , Pellizzer EP
Published: June 2018

Objective:

A systematic review and meta-analyses were performed to evaluate the efficacy of tooth color change and sensitivity of teeth following in-office bleaching with and without light gel activation in adult patients.

Methods:

This review was registered at PROSPERO (CRD 42017060574) and is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Electronic systematic searches of PubMed/MEDLINE, Web of Science, and the Cochrane Library were conducted for published articles. Only randomized clinical trials among adults that compared in-office bleaching with and without light activation with the same bleaching gel concentrations were selected. The outcomes were tooth color change and tooth sensitivity prevalence and intensity.

Results:

Twenty-three articles from 1054 data sources met the eligibility criteria. After title and abstract screening, 39 studies remained. Sixteen studies were further excluded. Twenty-three studies remained for qualitative analyses and 20 for meta-analyses of primary and secondary outcomes. No significant differences in tooth color change or tooth sensitivity incidence were found between the compared groups; however, tooth sensitivity intensity decreased when light sources were applied.

Conclusion:

The use of light sources for in-office bleaching is not imperative to achieve esthetic clinical results.

Published: June 2018

This work analyzes the fluidic dynamics of the particle extraction function of a nozzle used for the detection of explosives in simulation studies. The nozzle shape with inlet and outlet gas connection is able to extract particles generated by the laser drilling process. Drilling dependent parameters such as the diameter of the generated particles, initial particle velocity, and drilling hole depth are investigated in terms of the residence time of these particles within the extraction nozzle. Besides these, the performance of an applied inlet and outlet gas flow is examined.
Study of microstructure and mechanical properties of narrow-gap multi-layer hybrid laser-arc welded 316L austenitic stainless steel
Authors: Zhang Xiong , Mi Gaoyang , Wang Chunming
Published: June 2018

Hybrid laser-arc welding is an emerging welding technology that has a promising prospect in large-scale equipment manufacturing. In this paper, the butt joint of 316L austenitic stainless steel with 40 mm was made by using the multi-layer hybrid laser-arc welding process. On this basis, microstructure and properties of the welded joint were further investigated using an optical microscope, scanning electron microscope, and other methodologies. The results showed that the base materials consist of massive polygonal austenitic with a small amount of ferrites distributed in the grain boundary. What is more, the 316L austenitic stainless steel was heated and solidified in an F-A mode. Thus, ferrites distributed in the grain boundary were coarsened in the heat affected zone and the fusion zone was also composed of massive austenite and ferrites, which were approximately perpendicular to the fusion line. Owing to the different thermal cycles of different layers, the microstructure of the upper layer was coarser than that of the lower layer, and this microstructural inhomogeneity led to the variation of the hardness within the welded joint: hardness value of the upper weld was slightly higher than that of the lower weld. In addition, all tensile specimens were failed at the fusion zone and showed an obvious characteristic of ductile fracture with massive dimples distributing on it. Consequently, this study will broaden the scope of the application for the thick-plate hybrid laser-arc welding technology.
Precision structuring and functionalization of ceramics with ultra-short laser pulses
Authors: Friedrich Maria , Seiler Michael , Waechter Sebastian , Bliedtner Jens , Bergmann Jean P.
Published: June 2018

High-performance ceramics have been firmly established for the manufacturing of tools and components in the modern electronics industry and mechatronics. Various components such as circuit boards, bearings, and sensors benefit from their specific characteristics, such as wear resistance, stiffness, and electrical neutrality. Apart from these advantages, the brittleness and hardness of ceramics turn the mechanical processing into a challenging and difficult task. Against this background, modern laser technologies have already been used to process ceramics for many years, enabling a contactless and wear-free machining. However, regarding high precision applications, for instance, the drilling of micro-holes or the fabrication of well-defined cavities and three-dimensional structures, conventional laser processes reach their limits. Especially due to thermal influences of the laser radiation, brittle edges, stresses, and redeposited layers emerge. Ultrashort pulse lasers enable completely new processing qualities in these fields. The extremely short pulse durations within the pico- and femtosecond range lead to nonlinear absorption mechanisms and an almost athermal material removal. Thereby, dielectric materials can be processed precisely and gently. In the course of a comprehensive process study, the beam–material interactions of ultrashort pulses with ceramics have been investigated. Besides the material properties, the ablation process is influenced by a multitude of laser parameters, such as wavelength, pulse overlap, and fluence. In order to reveal the most important variables, the experiments have been conducted by applying modern statistical methods. Using alumina (Al2O3) as an example, it is shown how different parameter regimes lead to disparate process qualities and efficiencies. The generated models have been used to optimize industrially interesting applications, from the separation of ceramic printed circuit boards to the realization of precise design structures.

Authors: Faraj Nask Mohamad , A. Qadir Rebin
Published: June 2018

The root-knot nematode incited by Meloidogyne incognita is one of the top diseases affecting tomato production worldwide. Nematicides can be effectively used to control the disease, but is costly and harmful to human life and environmental pollution. Alternatively resistant cultivars can be used inexpensive and eco-friendly.  Resistance evaluation of five tomato cultivars (Red Rock, King Rock, Presto F1, Super Queen and Super Regina) were tested using randomized complete block design with five replications and three nematode inoculums (0, 500 and 1500 egg/second juvenile per pot). The statistical analysis gave significant differences among the genotypes, nematode densities level with their interactions. Among genotypes, Red Rock recorded significantly highest plant height (57.0) cm, Presto F1 (37.8) cm, King Rock (35.2) cm, Super Regina (30.1) cm and Super queen showed lowest (25.4) cm. As an alternative for managing the nematodes, further experiments are required in the field for applying plant resistances.

Evidence synthesis - The opioid crisis in Canada: a national perspective
Authors: Belzak Lisa , Halverson Jessica
Published: June 2018

Introduction

This review provides a national summary of what is currently known
about the Canadian opioid crisis with respect to opioid-related deaths and harms and
potential risk factors as of December 2017.

Methods

We reviewed all public-facing opioid-related surveillance or epidemiological
reports published by provincial and territorial ministries of health and chief coroners’ or
medical examiners’ offices. In addition, we reviewed publications from federal partners
and reports and articles published prior to December 2017. We synthesized the evidence
by comparing provincial and territorial opioid-related mortality and morbidity rates
with the national rates to look for regional trends.

Results

The opioid crisis has affected every region of the country, although some jurisdictions
have been impacted more than others. As of 2016, apparent opioid-related
deaths and hospitalization rates were highest in the western provinces of British
Columbia and Alberta and in both Yukon and the Northwest Territories. Nationally,
most apparent opioid-related deaths occurred among males; individuals between 30 and
39 years of age accounted for the greatest proportion. Current evidence suggests regional
age and sex differences with respect to health outcomes, especially when synthetic opioids
are involved. However, differences between data collection methods and reporting
requirements may impact the interpretation and comparability of reported data.

Conclusion

This report identifies gaps in evidence and areas for further investigation
to improve our understanding of the national opioid crisis. The Public Health Agency of
Canada will continue to work closely with the provinces, territories and national partners
to further refine and standardize national data collection, conduct special studies
and expand information-sharing to improve the evidence needed to inform public health
action and prevent opioid-related deaths and harms.

Published: June 2018

Nous avons quantifié la contribution des principales causes de décès et de surdose à
l’évolution de l’espérance de vie à la naissance et aux disparités en matière de sexe et de
situation socioéconomique en Colombie-Britannique. Entre 2014 et 2016, l’espérance de
vie à la naissance a diminué de 0,38 an et les décès par surdose (principalement liés aux
opioïdes) ont contribué à ce recul pour 0,12 an. L’analyse a également montré que le taux
plus élevé de mortalité par surdose constaté chez les hommes et les membres des catégories
socioéconomiques plus défavorisées a contribué à une diminution différentielle dans
ces deux groupes de l’espérance de vie à la naissance.

Canguilhem’s Concepts
Authors: Peña-Guzmán David Marcelo
Published: June 2018

In the 1950s, George Canguilhem became known in France as a vocal exponent of the philosophy of the concept, an approach to epistemology that treated science as the highest expression of human rationality and scientific concepts as the necessary preconditions for the manifestation of scientific truth. Philosophers of the concept, Canguilhem included, viewed concepts as the key to the study of science; and science, in turn, as the key to a substantive theory of reason. This article explains what concepts are for Canguilhem, how they are extracted from the history of the sciences, and why they continue to matter for contemporary debates in the History and Philosophy of Science (HPS).
When the Content to Be Taught Is a Norm
Authors: Xavier Roth
Published: June 2018

It has become customary since Foucault to present Canguilhem as a man whose work is voluntarily restricted to a particular domain of the history of science. Yet the current edition of his Complete Works reveals that Canguilhem has never considered himself a true historian of science. If he traced “the history of the formation, deformation and rectification of scientific concepts”, it is above all to nurture his profession of professor of philosophy with “unknown material”. On the assumption that Canguilhem subordinates the history of science to teaching, this article will try to make a further step and show that its inter-regional approach of knowledge can serve as a paradigm in educational sciences, when the knowledge to be transmitted is a-disciplinary and has a strong normative dimension.
Charting Links between Life, Science, and Technique

The article explores theoretical convergences between the work of Georges Canguilhem and Lucien Febvre on the theme of science and technique. In comparing the scholarship of both authors from the 1920s through 1940s, we endeavor to show that their critique of mechanistic determinism was rooted in the concept of the genres of life (not only human) and its creative interaction with the environment.

Harald Heppner’s science has also found its applicability in the various academic positions he has occupied throughout his life: President (1994-2001), then Vice-President of the Austrian Society for Eighteenth Century Studies (2008-2012) Director of the Department of History at the University of Graz (2011-2013), Chairman of the History Committee of the Austrian Defence Ministry (2005), General Coordinator of the Thirteenth International Congress of Eighteenth Century Studies. He is an honorary member of the historical department of the Romanian Academy (Iași Branch).
Harald Heppner was the initiator of the MA programme in Southeast European History, which he organized together with the University of Ljubljana and the Babeş-Bolyai University of Cluj-Napoca. The students of the university in Cluj have been the beneficiaries of mobilities that have allowed them to complete their training during the semesters they spent in Graz under the supervision of Harald Heppner.
Does Molinism Reconcile Freedom and Foreknowledge?
Authors: Mooney Justin
Published: June 2018

John Martin Fischer has argued that Molinism does not constitute a response to the argument that divine foreknowledge is incompatible with human freedom. I argue that T. Ryan Byerly’s recent work on the mechanics of foreknowledge sheds light on this issue. It shows that Fischer’s claim is ambiguous, and that it may turn out to be false on at least one reading, but only if the Molinist can explain how God knows true counterfactuals of freedom.

The spread and prediction of Ebola virus
Authors: Chen Yingyou , Wen Mingzhe , Geng Minghao
Published: June 2018

Ebola virus is a potent infectious disease virus that can cause Ebola haemorrhagic fever caused by human and primate. It has high mortality and easy infectivity to form a great obstacle to the steady development of human society. The profound understanding of the virus is particularly important harm. In this paper, a number of mathematical models are established to solve this problem. The software is used to analyze and predict the propagation of Ebola virus. The residual analysis is used to test the model. Finally, the effects of various control measures on controlling the epidemic are analyzed. In order to solve the problem, we will establish the infectious disease model to dynamically describe the spread of the virus in the 'virtual orangutan population'. Considering that the latent population is analyzed in this question, we will improve the model. Join the latent group (), and the migrants are divided into self-healing () and the dead (), to establish a suitable solution to this problem model. According to the relevant data given in the title, differential equations were established. For the second question, this question involves the one-way transmission of the virus across the species, so we can improve the model, on the basis of human contact with orangutans infected groups, the establishment of a one-way model to solve this problem. On the basis of the problem one, the differential equation is established, the model is predicted and tested. In the case of question 3, the number of human susceptible groups is much higher than that of the orangutan infection group by comparing the relevant data with the increase of the cure rate to 80% after the intervention of the outside experts. Therefore, the original data of human populations from experts can be ignored. Since then the virus spreads within a single species, the differential equation can be established according to the model in question 1 and the data values in the virtual human population are predicted. For question 4, the effect of the measures such as the strict enforcement of the various epidemic control measures and the improvement of the drug effect on the control of the epidemic are analyzed by comparing the above-mentioned models with the control measures.
Effects of enhanced UV-B radiation on the content of flavonoids in mesophyll cells of wheat
Authors: Ou Shilong , Lu Shengqian , Yang Shenning
Published: June 2018

The content of flavonoids in mesophyll cells of wheat was studied under the condition of enhanced UV-B radiation intensity. In this experiment, four groups of six days of control were treated with He-Ne laser group (L), enhanced UV-B radiation group (B), He-Ne laser and UV-B combined treatment group (B + L ), Normal light group (CK). Since the flavonoids carry some unsubstituted hydroxyl or glycosyl groups, it is a polar compound. By the 'similar compatibility' principle, they have some level of solubility in polar solvents, such as methanol, ethanol, n-butanol, propanol, and water. In this experiment, 70% ethanol was used to extract flavonoids. Finally, the total content of flavonoids in mesophyll cells was determined by visible spectrophotometry. The OD value of flavonoids was determined by rutin reagent 'The standard curves because rutin is a representative of flavonoids, it scavenging the role of free radicals significantly. The results showed that when the UV-B UV radiation intensity was enhanced, the content of flavonoids in wheat mesophyll cells increased, that is, the content of flavonoids in wheat leaves was higher than that in UV-B Strength was positively correlated. The results showed that the content of flavonoids in the mesophyll cells of the four control groups was the same as that of the B group> BL group> CK group> L group. With the prolonging of the treatment time of wheat, the content of flavonoids in wheat leaves at jointing-booting stage was significantly higher than that in seedling stage and panicle stage. This means that flavonoids are a protective substance that absorbs UV-B in plants, that is, the absorption of UV-B by flavonoids reduces the damage of UV-B to organs in plants [8] [10]; UV-B The smaller the damage, the less the content of flavonoids; laser damage caused by UV-B have a certain role in the repair. In this study, we further studied the eﬀect of enhanced UV-B radiation on the content of flavonoids in mesophyll cells of wheat. The eﬀects of UV-B radiation on the content of flavonoids in wheat were studied. Whether it has a very important significance for wheat has become a stress [5].

In the current era, electromagnetic radiation is everywhere. Every day electromagnetic radiation and static electricity caused by a variety of hazards. So, anti-electromagnetic radiation and anti-static awareness gradually enjoys popular support, more attention are gained by people on the anti-electromagnetic radiation and anti-static. This caused radiation protection and anti-static clothing industry’s rise by the day. Radiation protection and anti-static clothing will enter various households to provide a certain amount of protection to the people's health. We discuss two parts in this paper, specifically from the eﬀects of the electromagnetic radiation and electrostatic eﬀects which started on radiation clothing and anti-static clothing. The main contents of this paper are as follows: The first part of the definition of electromagnetic radiation and its brief introduction, while explaining the types of electromagnetic radiation and electromagnetic radiation sources in daily lives, followed by the emphasis of serious harms on electromagnetic radiation on human health It is precisely because of electromagnetic radiation on people's lives have serious threat, that makes the development of radiation protection. This follows the basic introduction of the radiation suit and the development of radiation protection clothings. The development of radiation protection suits is an established industry. Materials made of radiation protection are constantly changing, but their basic working principle has not changed. Followed by the introduction of the basic principles of radiation protection clothings, we theoretically present specific analysis and demonstration. However, the theoretical analysis and practice is often consists a certain gap, so we highlight a few actual situations on the impact of radiation protection clothings. Finally, we present a simple discussion on wide range of applications of radiation protection clothings.

Silane coatings are suitable for various applications of metal surfaces, such as forming a corrosion protection layer or as a primer for subsequent coating. In this work, bis-1,2- (triethoxy) ethane (BTSE) was used as a precursor on a 99.99% aluminum substrate for deposition of the coating, with three diﬀ erent techniques: dipping (water-based solution ), Vacuum plasma and atmospheric plasma. (IRRAS), X-ray photoelectron spectroscopy (XPS) and fi eld emission gun scanning electron microscopy (FE-SEM) were used to characterize the structure, composition and surface morphology of silane coating. The purpose of this study is to compare the surface and body properties of membranes prepared by three different methods to obtain information on how BTSE molecules are modified by deposition techniques. The results show that in addition to the more traditional wet dip coating, the film can also be vacuum and atmospheric plasma deposition. The vacuum plasma deposition layer can be considered as an organic and inorganic mixture, which can be obtained by dipping as well as the silane layer. However, atmospheric plasma treatment leads to the formation of more inorganic fi lms containing Si-O. Photon spectroscopy and infrared spectroscopy showed the presence of Si-O-Si bonds, while IRRAS measurements showed Si-O-Si, Si-O-C, Si-O and Si-CH3 absorption bands.

Objective Autosomal recessive polycystic kidney disease (ARPKD) is a rare inherited renal cystic disease involving multiple organs. It is caused by mutations in the PKHD1 gene. Here, we investigate the gene mutations in a family affected by ARPKD. Methods Genomic DNA was extracted from peripheral blood leukocytes obtained from the subjects, by means of targeted gene capture and next generation sequencing technologies for mutation screening, and were confirmed by Sanger sequencing. Results Two heterozygous mutations of PKHD1, c.6890T>C (p.Ile2297Thr) and c.11215C>T (p.Arg3739Trp), located in exons 43 and 62, respectively, were identified in the patient. Furthermore, the father and mother were revealed to be carriers of heterozygous c.6890T>C (p.Ile2297Thr) and c.11215C>T (p.Arg3739Trp) mutations, respectively. Mutation of c.11215C>T (p.Arg3739Trp) has been found in the ARPKD Mutation Database (http://www.humgen.rwth-aachen.de) but mutation of c.6890T>C (p.Ile2297Thr) has not been reported. Conclusions Compound heterozygous PKHD1 mutations were elucidated to be the molecular basis of ARPKD in this patient. The newly identified c.6890T>C (p.Ile2297Thr) mutation in the patient expands the mutation spectrum of the PKHD1 gene. Targeted gene capture and next generation sequencing are suitable for genetic diagnosis of single-gene inherited diseases like ARPKD, in which the pathogenic gene is large.
