Formation of alkyne-bridged ferrocenophanes using ring-closing alkyne metathesis on 1,1’-diacetylenic ferrocenes
Authors: Bittner Celine , Bockfeld Dirk , Tamm Matthias 
Published: July 2019

Novel alkyne-bridged ferrocenophanes [fc{CO2(CH2)nC≡}2] (2a: n = 2; 2b: n = 3) were synthesized from the corresponding terminal diacetylenic ferrocenes [fc{CO2(CH2)nC≡CH}2] (1a: n = 2; 1b: n = 3) through ring-closing alkyne metathesis (RCAM) utilizing the highly effective molybdenum catalyst [MesC≡Mo{OC(CF3)2CH3}3] (MoF6; Mes = 2,4,6-trimethylphenyl). The metathesis reaction occurs in short time with high yields whilst giving full conversion of the terminal alkynes. Furthermore, the solvent dependant reactivity of 2a towards Ag(SbF6) is investigated, leading to oxidation and formation of the ferrocenium hexafluoroantimonate 4 in dichloromethane, whereas the silver(I) coordination polymer 5 was isolated from THF solution.
Small Planets in the Galactic Context: Host Star Kinematics, Iron, and Alpha-element Enhancement
Authors: Bashi Dolev , Zucker Shay 
Published: July 2019

Abstract
We explored the occurrence rate of small close-in planets among Kepler target stars as a function of the iron abundance and the stellar total velocity

. We estimated the occurrence rate of those planets by combining information from the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) and the California-Kepler Survey and found that iron-poor stars exhibit an increase in the occurrence with

from f < 0.2 planets per star at

< 30

to f ∼ 1.2 at

> 90

. We suggest this planetary profusion may be a result of a higher abundance of α elements associated with iron-poor, high-velocity stars. Furthermore, we have identified an increase in small-planet occurrence with iron abundance, particularly for the slower stars (

< 30

), where the occurrence increased to f ∼ 1.1 planets per star in the iron-rich domain. Our results suggest there are two regions in the ([Fe/H], [α/Fe]) plane in which stars tend to form and maintain small planets. We argue that analysis of the effect of overall metal content on planet occurrence is incomplete without including information on both iron and α-element enhancement.
The Evolution of the Interstellar Medium in Post-starburst Galaxies

Published: July 2019

Abstract
We derive dust masses (M
dust) from the spectral energy distributions of 58 post-starburst galaxies (PSBs). There is an anticorrelation between specific dust mass (M
dust/M
⋆) and the time elapsed since the starburst ended, indicating that dust was either destroyed, expelled, or rendered undetectable over the ∼1 Gyr after the burst. The M
dust/M
⋆ depletion timescale,

, is consistent with that of the CO-traced

, suggesting that dust and gas are altered via the same process. Extrapolating these trends leads to the M
dust/M
⋆ and

values of early-type galaxies (ETGs) within 1–2 Gyr, a timescale consistent with the evolution of other PSB properties into ETGs. Comparing M
dust and

for PSBs yields a calibration, log

, that allows us to place 33 PSBs on the Kennicutt–Schmidt (KS) plane,

. Over the first ∼200–300 Myr, the PSBs evolve down and off of the KS relation, as their star formation rate (SFR) decreases more rapidly than

. Afterwards,

continues to decline whereas the SFR levels off. These trends suggest that the star formation efficiency bottoms out at 10−11 yr−1 and will rise to ETG levels within 0.5–1.1 Gyr afterwards. The SFR decline after the burst is likely due to the absence of gas denser than the CO-traced H2. The mechanism of the M
dust/M
⋆ and

decline, whose timescale suggests active galactic nucleus/low-ionization nuclear emission-line region feedback, may also be preventing the large CO-traced molecular gas reservoirs from collapsing and forming denser star-forming clouds.

Introduction: Antibiotic-loaded bone cements of poly(methyl methacrylate) are considered as very useful biomaterials for the management of corporal deep osseous infections. However, the high prevalence of resistant germs and polymicrobial infections makes it necessary to search for new formulations of bone cements containing antibiotics for local antibacterial therapy. In this work, bone cements loaded with drugs with different mechanism of action were evaluated to determine its antibacterial effectiveness on Pseudomonas aeruginosa.
Methodology: Poly(methyl methacrylate) cements loaded with 10 wt.% of Oleozon®, mixtures of Ciprofloxacin/Meropenem and Ciprofloxacin/Meropenem/Oleozon® were prepared. The in vitro drugs release in water was followed by UV-Vis spectroscopy, and their antibacterial activity against Pseudomonas aeruginosa was evaluated for 11 days using the microdilution method.
Results: All the extracts demonstrated an inhibitory effect on the growth of the strain during the whole trial period. Extracts from cement with Oleozon® only presented a total antibacterial inhibitory effect during 20 hours for the extracts taken at day 1 while the extracts from the cements loaded with mixtures of Ciprofloxacin/Meropenem and Ciprofloxacin/Meropenem/Oleozon® showed complete inhibition of the growth of the microorganism, even at 11 days. At the end of the trial period, some of the drugs remained inside the matrices, indicating that they can be released for a longer time in treatments.
Conclusions: The results indicated a positive antibacterial effect by the combined used of the two or the three drugs tested against the Gram-negative bacilli Pseudomonas aeruginosa, so these proposal may be a valid alternative to be considered by surgeons.
En Corée, des migrants bons à marier

Published: July 2019

Programme gouvernemental, le « multiculturalisme » tel qu’il est conçu en Corée du Sud relève davantage d’une simple coexistence entre les Coréens et les étrangers que d’un pluralisme culturel reposant sur la reconnaissance des différences. Officialisée en 2006, cette politique vise principalement l’assimilation des femmes immigrées par le mariage avec des Coréens. Pour le gouvernement, cette politique offre l’avantage de maintenir l’homogénéité culturelle du pays tout en apportant des solutions aux problèmes démographiques du pays.

Published: July 2019

After cardiac surgery operation, severe complications may occur in patients due to hypertension. To decrease the chances of complication it is necessary to reduce elevated mean arterial pressure (MAP) as soon as possible. Continuous infusion of vasodilator drugs, such as sodium nitroprusside (Nipride), it is used to reduce MAP quickly in most patients. For maintaining the desired blood pressure, a constant monitoring of arterial blood pressure is required and a frequently adjust on drug infusion rate. The manual control of arterial blood pressure by clinical professionals it is very demanding and time consuming, usually leading to a poor control quality of the hypertension. The objective of the study is to develop an automated control procedure of mean arterial pressure (MAP), during acute hypotension, for any patient, without changing the controller. So, a multi-model adaptive predictive methodology was developed and, for each model, a Predictive Controller can be a priori designed (MMSPGPC). In this paper, a sensitivity analysis was performed and the simulation results showed the importance of weighting factor (Ï†), which controls the initial drug infusion rate, to prevent hypotension and thus preserve patient's health. Simulation results, for 51 different patients, showed that the MMSPGPC provides a fast control with mean settling time of 04:46 min, undershoots less than 10 mmHg and steady-state error less than ± 5 % from the MAP setpoint.
Parfum de bonté et odeur de sainteté
Authors: Wicky Érika 
Published: July 2019

Émanations invisibles et impalpables, les odeurs sont au cœur des liens étroitement noués au xixe siècle entre hygiène corporelle et moralité. Comme l’a bien montré Alain Corbin, les conceptions de l’olfaction renforcent l’articulation entre le corps et l’esprit, instaurant entre senteurs et vertus un rapport de causalité. Ainsi, l’odeur sous-tend souvent la dénonciation et l’opprobre des prostituées, mais elle joue aussi un rôle essentiel dans l’éducation des jeunes filles à laquelle est apporté, durant la seconde moitié du xixe siècle, un soin tout particulier.
Effects of tebufenozide on the assemblage of moths (Lepidoptera) in an operational spruce budworm (Lepidoptera: Tortricidae) suppression programme

Published: July 2019

AbstractTebufenozide (Mimic) kills Lepidoptera larvae that ingest it. Aerial applications of tebufenozide were made against spruce budworm (Choristoneura fumiferana(Clemens)) (Lepidoptera: Tortricidae) in boreal forest in Manitoba, Canada, in 1999 and 2000. In 2000 and 2001, moths in sprayed and unsprayed plots were sampled with light traps; trapping was supplemented by foliage sampling. Relative to unsprayed plots, catches of spruce budworm moths in plots sprayed in 1999 and 2000 were depressed in 2000, but not in 2001. Host tree defoliation was reduced in 2000 by 1999 and 2000 applications; the 2000 application reduced numbers of spruce budworm larvae in 2000 and 2001. Multivariate analysis revealed negative effects of tebufenozide application on two species of non-target moths in 2000 and no negative effects in 2001. Negatively affected species have larvae feeding in the tree canopy at the time of spray application. Higher catches of non-target species in sprayed treatments were observed for three species in 2000 and two species in 2001. We conclude that tebufenozide can depress the numbers of spruce budworm larvae and provide foliage protection during the year of application and the following year, and that negative effects on non-target species are detectable for about 15 months after application.

Abstract
A bismuth oxide based multi-component glass system, xH3BO3-yBi2O3-(1-x-y-δ)MO-δ·REO with MO=TiO2, BaO, ZnO, Fe2O3, etc., and lanthanum series based rare earth oxides (REO), for making downhole high-pressure and high-temperature (HPHT) electrical feedthrough package, has been developed using high-temperature melt-quenching and sintering technologies. By properly controlling phase structures in the material manufacturing processes, the obtained sealing materials have shown moisture-resistant properties in their monoclinic and tetragonal mixed phase structures, but strongly hydrophobic properties in their covalent bond tetragonal phase. The sealed electrical feedthrough packages have been evaluated under boiling water immersion and 200°C/30,000PSI water-fluid simulated downhole harsh environments. The post measurement has demonstrated to be greater than 1.0×1014 Ω electrical resistance. This paper will show that such a high-bonding-strength and high-insulation-strength sealing material could be used to seal electrical feedthroughs and connectors for 300°C/30,000PSI downhole and subsea wireline, logging while drilling (LWD), and measurement while drilling (MWD) tools' signal, data, and electrical power transmissions.
Bonding strength of Cu/Cu joints using sintering process of micro-sized Cu particles for high-temperature application
Authors: Nishikawa Hiroshi , Liu Xiangdong 
Published: July 2019

Abstract
Recently the new SiC power device provides the possibility to develop the next-generation power conversion circuit with high efficiency and high power density. The SiC power device can operate with significant lower power loss and higher operating temperature, which contributes to miniaturization and higher performance of power modules. To assemble these power modules, the high temperature packaging technology such as die attach process is needed. As a die attach process, we have proposed a simple oxidation-reduction bonding (ORB) process to achieve good Cu-to-Cu joints using micro-sized Cu particles. In this study, the effect of the oxidation-reduction process on the surface morphology of Cu particles was evaluated by SEM observation, and the shear strength of the Cu-to-Cu joints was investigated. As a result, the bonding using micro-sized Cu particles was successfully achieved and the shear test results showed that the joints by ORB process had a shear strength of more than 20 MPa.

Authors: Braun Sebastian , Kordas Norbert , Utz Alexander , Kappert Holger , Kokozinski Rainer 
Published: July 2019

Abstract
In this paper we present an integrated circuit for inductive proximity switches which requires very few external components and can operate under ambient temperatures up to 250 °C. The sensor system is realized in the Fraunhofer IMS H035 technology which was specifically developed for high temperature operation. The core of the circuit is built of an oscillator which is equipped with a peak detector and readout electronics for threshold detection, references and voltage regulators to provide the necessary internal voltages as well as extensive trimming capabilities to compensate for temperature effects. The circuit can be operated from a single dc-voltage supply from 12 to 35 Volts. Calibration data can be stored in an internal EEPROM. Switching distance and hysteresis are programmable for adapting the circuit to a wide range of different detector coils and sensor geometries. Two output signals are provided that can be independently set to function as push/pull or single ended switches with programmable polarity. The only external components required are blocking capacitors for supply voltage stabilization and the LC resonator circuitry. Reverse polarity protection and special high temperature ESD and clamping structures are also fully integrated on the silicon die.

Published: July 2019

Background & objectives:
In contrast to Caucasians of European origin, the aetiology of diabetes mellitus (DM) in young adults in other ethnic groups, including Indians is likely to be heterogeneous and difficult to determine. This study was undertaken to determine the aetiology of diabetes in young Indian adults using a protocol-based set of simple clinical and investigation tools.

Methods:
In this prospective study, 105 Indian young adults with diabetes (age at onset 18-35 yr; duration <2 yr) were studied for a period of 1-3 years. Pancreatic imaging, fasting C-peptide, islet antibodies (against glutamic acid decarboxylase, tyrosine phosphatase and zinc transporter-8) and mitochondrial A3243G mutational analysis were performed in all patients. Four patients were screened for maturity-onset diabetes of the young (MODY) using next-generation sequencing.

Results:
Type 1 and type 2 diabetes mellitus (T1DM and T2DM) were equally frequent (40% each), followed by fibrocalculous pancreatic diabetes (FCPD, 15%). Less common aetiologies included MODY (2%), mitochondrial diabetes (1%) and Flatbush diabetes (2%). There was considerable phenotypic overlap between the main aetiological subtypes. Elevated islet antibodies were noted in 62 per cent of T1DM patients [positive predictive value (PPV) 84%; negative predictive value (NPV) 78%] while low plasma C-peptide (<250 pmol/l) was present in 56 per cent of T1DM patients [PPV 96% (after excluding FCPD), NPV 72%]. Using these tests and observing the clinical course over one year, a final diagnosis was made in 103 (99%) patients, while the diagnosis at recruitment changed in 23 per cent of patients.

Interpretation & conclusions:
The aetiology of diabetes in young adults was heterogeneous, with T1DM and T2DM being equally common. FCPD was also frequent, warranting its screening in Indian patients. Testing for islet antibodies and C-peptide in this age group had good PPV for diagnosis of T1DM.

Published: July 2019

Background & objectives:
Substance use disorders are a major public health concern in Punjab. However, reliable estimates of prevalence of substance use disorders are not available for the State. The present study reports estimates of prevalence of substance use disorders in Punjab, conducted as part of National Mental Health Survey, India.

Methods:
Using multistage stratified random cluster sampling, 2895 individuals from 719 households of 60 clusters (from 4 districts of Punjab) were interviewed. Mini International Neuropsychiatric Interview and Fagerstrom nicotine dependence scale were used to assess substance use disorders.

Results:
The sample comprised almost equal numbers of males and females. Nearly 80 per cent had less than or equal to high school education, and 70 per cent were married. The weighted prevalence of alcohol and other substance use disorders was 7.9 and 2.48 per cent, respectively. The prevalence of tobacco dependence was 5.5 per cent; 35 per cent households had one person with substance use disorder. The prevalence was highest in the productive age group (30-39 yr), urban metro and less educated persons. The prevalence of alcohol and other substance use disorders was much higher in Punjab as compared to other States where survey was done. Tobacco dependence was lowest in Punjab. Majority (87%) of the persons with substance use disorders did not suffer from any other mental disorder. Treatment gap was 80 per cent.

Interpretation & conclusions:
Punjab has a high burden of substance use disorders. The estimates will help clinicians and policymakers to plan the strategies against the menace of substance use disorders effectively.

Published: July 2019

Background & objectives:
There is a paucity of literature on the cognitive profiles of vascular dementia (VaD) in India. The current study was undertaken to investigate the pattern of cognitive deficits in patients with VaD.

Methods:
Fifty patients fulfilling the Diagnostic and Statistical Manual of Mental Disorders-IV criteria of dementia and National Institute of Neurological Disorders and Stroke - Association Internationale pour la Recherche et l'Enseignement en Neurosciences criteria for VaD were assessed using Mini Mental State Examination, Kolkata Cognitive Screening Battery and other relevant tests including magnetic resonance imaging of brain.

Results:
Twenty patients had small vessel dementia, whereas the least common was haemorrhagic dementia in four patients. In patients with small vessel dementia, apart from memory, all patients had problem in attention and executive function, whereas 12 patients had visuoconstructional deficit and eight patients had language problem. In a total of 12 patients with large vessel dementia, apart from memory, executive dysfunction and visuoconstructional deficit were noted in 10 patients, whereas attention deficit was noted in eight patients. Attention was found to be more involved in small-vessel dementia than large-vessel dementia though all had memory impairment (P<0.01).

Interpretation & conclusions:
Small vessel dementia was the commonest subtype of VaD in our study. Memory, attention and executive functions were predominantly affected in patients with VaD. Attention was significantly more involved in small vessel dementia than large vessel dementia. Further studies with large sample size need to be done in different regions of the country.

Authors: Nongmaithem Onila , Shantikumar T. , Dutta Sudip 
Published: July 2019

Background & objectives:
Different coproculture techniques have been developed for culturing the hookworm (HW) larvae for morphological identification in the resource-limited settings. The objective of this study was to compare the performances of Harada-Mori culture (HMC), agar plate culture (APC) and modified APC (MAPC) of HW positive stool specimens for identification of HW species in East Sikkim.

Methods:
This prospective study was done in East Sikkim from May 2015 to May 2016. Stool and blood samples were collected from paediatric patients with gastrointestinal symptoms. The HW positive stool specimens by microscopy were subjected to HMC, APC and MAPC techniques to harvest HW larvae. Stoll's dilution egg count for determining egg intensity and blood parameters were performed in all the 12 HW-positive patients.

Results:
Twelve of the 180 samples were found positive for HW by microscopy and predominance of Necator americanus (75%) over Ancylostoma duodenale (25%) was observed. Blood parameters results showed high pack cell volume (PCV) values in 78.6 per cent, anaemia in 75 per cent and high eosinophil count in most patients. Stoll's dilution egg count showed moderate infection in 66.6 per cent, light and heavy infections in 16.7 per cent each.

Interpretation & conclusions:
Our results showed that APC yielded 100 per cent results and was easier to perform in the laboratory compared to MAPC and HMC techniques.
