Abstract
We present the discovery and the photometric and spectroscopic study of H-rich Type II supernova (SN) KSP-SN-2016kf (SN2017it) observed in the KMTNet Supernova Program in the outskirts of a small irregular galaxy at z ≃ 0.043 within a day of the explosion. Our high-cadence, multi-color (BVI) light curves of the SN show that it has a very long rise time (t
rise ≃ 20 days in the V band), a moderately luminous peak (M

V
≃ −17.6 mag), a notably luminous and flat plateau (M

V
≃ −17.4 mag and decay slope s ≃ 0.53 mag per 100 days), and an exceptionally bright radioactive tail. Using the color-dependent bolometric correction to the light curves, we estimate the 56Ni mass powering the observed radioactive tail to be 0.10 ± 0.01 M
☉, making it an H-rich Type II SN with one of the largest 56Ni masses observed to date. The results of our hydrodynamic simulations of the light curves constrain the mass and radius of the progenitor at the explosion to be ∼15 M
☉ (evolved from a star with an initial mass of ∼18.8 M
☉) and ∼1040 R
☉, respectively, with the SN explosion energy of ∼1.3 × 1051 erg. The above-average mass of the KSP-SN-2016kf progenitor, together with its low metallicity of

obtained from spectroscopic analysis, is indicative of a link between the explosion of high-mass red supergiants and their low-metallicity environment. The early part of the observed light curves shows the presence of excess emission above what is predicted in model calculations, suggesting there is interaction between the ejecta and circumstellar material. We further discuss the implications of the high initial mass of the progenitor and the low-metallicity environment of KSP-SN-2016kf for our understanding of the origin of Type II SNe.
Tendances et cycles de productivité par grande branche marchande pour l’économie française
Authors: Ducoudré Bruno 
Published: August 2019

Nous décomposons les demandes de travail par grande branche marchande (industrie, construction, services marchands) afin de mesurer les tendances de productivité sectorielles et leur évolution. Les estimations d’équations de demandes de facteur travail indiquent un ralentissement des gains de productivité tendanciels principalement dans l’industrie, cohérent avec la littérature existante. Conjugué à la baisse de la part de l’industrie dans l’emploi, cela explique 90 % de la baisse du taux de croissance de la productivité tendancielle depuis les années 1980. Sur la période récente, la tendance de productivité croîtrait à un rythme de 0,9 % par an (1,9 % par an dans l’industrie, 0,8 % dans les services et 0,1 % dans la construction).
Ten-Year Outcomes of Progressive Keratoconus Management With the Athens Protocol (Topography-Guided Partial-Refraction PRK Combined With CXL)
Authors: Kanellopoulos Anastasios John 
Published: August 2019

PURPOSE:
To report the safety and long-term efficacy of topography-guided partial-refraction PRK combined with corneal cross-linking (CXL) (the Athens Protocol), refractive, topographic, and pachymetric changes of keratoconic eyes treated were studied.

METHODS:
Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refraction, keratometry, qualitative and quantitative assessment of corneal keratometric, and pachymetric properties recorded by topography and tomography were evaluated for 10 years postoperatively.

RESULTS:

A total of 144 eyes were followed up for a mean 128 ± 4 months (range: 120 to 146 months). Mean UDVA markedly improved at 1 year (0.19 ± 0.17 to 0.53 ± 0.21 decimal) with further improvement to 0.55 ± 0.19 decimal at 10 years. CDVA increased from 0.59 ± 0.21 to 0.80 ± 0.17 decimal at 1 year and further to 0.81 ± 0.19 decimal at 10 years. Corneal thickness decreased from 468.74 ± 35.05 to 391.14 ± 40.07 μm at 1 year (
P
< .01) and up to 395.42 ± 32.21 μm at 10 years. Steep keratometry decreased from 50.57 ± 2.80 to 45.87 ± 2.70 diopters (D) (
P
< .01) at 1 year and to 44.00 ± 3.22 D at 10 years. Maximum keratometry decreased from 53.43 ± 2.97 to 46.17 ± 1.18 D at 1 year and 44.75 ± 2.14 D at 10 years (
P
< .01). A total of 94.4% demonstrated ectasia stabilization and 3.5% showed progressive “overcorrection” or “hyperopic” shift.

CONCLUSIONS:
The Athens Protocol confirms long-term safety and efficacy for corneal ectasia and visual function. Most parameters had little change after 1 year, through year 10.

Published: August 2019

Abstract. For many years real-time climate monitoring for temperature over France has been performed using a national index built by averaging the daily mean temperatures of constant subset of 30 stations with long-term series. In order to derive climate indices at finer scales, a spatialization of extreme daily temperatures (called ANASTASIA) had been produced on a 1 km regular grid using a regression-kriging method. The production covers 1947 to present period. Cross-validation shows low biases after the 1960s. The temporal homogeneity of the product is satisfying at the national scale from the 1970s. However, a high impact of the network density has been found and the use of a too coarse observation network deteriorates the analysis creating temporal heterogeneities. Finally, the ANASTASIA analysis has been used for real-time monitoring over France and detection of heat and cold wave episodes. The new products based on ANASTASIA are consistent with the current operational ones at national scale while bringing added values at local scales.
Delirium Reduced With Intravenous Acetaminophen in Geriatric Hip Fracture Patients
Authors: Connolly Keith P. , Kleinman Rachel S. , Stevenson Kim L. , Neuman Mark D. , Mehta Samir N. 
Published: August 2019

Introduction:
Postoperative delirium is associated with opioid use in the elderly and is a common complication of geriatric hip fractures, with reported incidences from 16% to 70%. Intravenous (IV) acetaminophen is a safe and efficacious medication in elderly patients and has been shown to reduce use of opioids after hip fracture. At our institution, IV acetaminophen was implemented for the first 24 hours postoperatively as part of a multimodal pain control regimen for geriatric hip fracture patients.

Methods:
A retrospective review of 123 hip fragility fracture patients older than 60 years from January 2016 to December 2016 was performed. Delirium was identified using a validated chart–based review tool. The rate of delirium, as well as length of stay, pain scores, opioid administration, need for one-to-one supervision, and readmissions were analyzed.

Results:
Sixty-five patients (52.8%) received IV acetaminophen during this period. No notable differences were found in baseline characteristics between groups. Ten of 65 patients receiving IV acetaminophen postoperatively experienced delirium compared with 19 of 58 who did not receive the medication (15.4% versus 32.8%, P = 0.024). The IV acetaminophen group also required fewer doses of IV opioids on postoperative day 1 (0.37 versus 1.19 doses, P = 0.008), were less likely to require one-to-one supervision (9.2% versus 24.1%, P = 0.025), and had shorter lengths of hospital stay (6.37 versus 8.47 days, P = 0.037). Readmission rates and discharge dispositions did not vary with significance between the two groups.

Conclusion:
The inclusion of IV acetaminophen as part of a multimodal pain regimen led to fewer episodes of delirium in this study. The reduced use of opioids immediately after surgery may have been a large factor in this outcome. Lower delirium rates may reduce the utilization of inpatient resources for direct patient supervision and provide for shorter hospital stays.

Armoede onder kinderen: een pleidooi voor een kindgerichte aanpak van armoedebestrijding
Het aantal kinderen in Nederland dat in armoede leeft, is hoog en daalt al jarenlang nauwelijks. De bestrijding van deze problematiek blijkt complex. In dit artikel worden de knelpunten in het huidige beleid beschreven en wordt een andere aanpak bepleit waarbij niet het gezinsinkomen van de ouder(s)/verzorger(s) maar het kind centraal staat. Door voor die benadering te kiezen, menen de auteurs dat meer tegemoet zal worden gekomen aan de behoeften en belangen van kinderen. Dit artikel is in samenwerking met het Kinderrechtencollectief geschreven.

The Use of Private Maritime Security Contractors (PMSC) or Privately Contracted Armed Security Personnel (PCASP) on Board of Belgian and Dutch Merchant Ships – A Comparative Analysis of the Legislation of European Flag States
Until recently, Dutch merchant ships could not rely on privately contracted maritime security staff to protect themselves against pirates. On the one hand, the argument prevailed that the State had to retain the monopoly on the use of force and, on the other hand, one also feared for the escalation of violence or international incidents. Nowadays, however, more and more European countries allow for the use of privately contracted armed security personnel on board merchant ships. As a result, the Dutch Parliament has adopted a bill containing rules for the use of armed private security guards on board Dutch maritime merchant ships (Law to Protect Merchant Shipping 2019 (published in the Dutch official Gazette on June 7th, 2019)).The author addresses the question whether because of the new law a level playing field will emerge with the Merchant Navies from the neighboring Flag States of Belgium, the United Kingdom, Spain and Denmark, presenting a comparative analysis of their domestic legislation.The Dutch law clearly regulates the use of force and the master has the final responsibility for everything that happens under his authority. In principle, the security guards may only apply violence as the master has determined that it is necessary. Innovative is that there is a reporting obligation whereby every incident should be reported with images and sound recordings. It seems, however, that the law is especially made to protect and secure and not necessarily to provide a solution for situations in which pirates come on board.It is clear that the intention of the legislator is to leave the monopoly on the use of force in the hands of the State. However, the adoption of this law to protect merchant shipping could constitute a first step in enabling the use of force by other actors than the State, which in itself is groundbreaking. Before being able to go on this road, there are still countless political (mainly related to the sovereignty of a State) and legal challenges (mainly concerning the use of force and respect for human rights) to be addressed.

BackgroundCellular therapy clinical applications require large-scale production of stem cells. Therefore, abundance, ease of isolation, and proliferative potential are the most important factors in choosing the appropriate source of cells for transplantation studies. Multipotent stem cells obtained from periodontal ligament (PDL) can be used in periodontal tissue regeneration. In this study, we aimed to evaluate and compare the characteristics of periodontal ligament stem cells (PDLSCs), extracted by either enzymatic digestion or explant methods, and expanded using two different serum types: fetal bovine serum (FBS) and xeno-free platelet lysate (PL).MethodsExpanded PDLSCs were assessed for their proliferation capacity, surface markers expression, colony formation, differentiation potential and ability to self-renewal. Most importantly, PDLSCs were evaluated for their ability to produce osteoblastsin vitro.ResultsPDLSCs isolated by explant method and expanded in PL serve as a promising source of stem cells for osteoblasts regeneration. These cells showed higher proliferation capacity, they retained their stemness characteristics throughout the passages and they revealed an increase in the expression level of osteogenic markers, without showing any karyotypic abnormalities after cell expansion.ConclusionsPDLSCs produced using explant extraction method and expanded in cell culture media supplemented with PL provide an excellent source of xeno-free cells for the generation of functional osteoblasts.

Front line demonstrations (FLDs) were conducted by pearl millet Research Station, JAU, Jamnagar on 313 farmers’ field in 125 hectares of different 98 villages of Gujarat state during summer season of 2015 to 2019. Prevailing farm practices were treated as control for comparison with recommended package i.e. improved variety (GHB 558, GHB 538, GHB 732), seed rate 4 kg/ha, timely sowing (15 Feb to 15 March), line sowing with spacing of 60 cm (R-R) and 10-12 cm (P-P), balanced use of fertilizers (NPK @120:60:0 kg/ha, thinning 15 days after sowing, weed management (pre emergence spray of Atrazin @ 0.5 kg/ha and one hand weeding), proper critical stage apply 8-10 irrigation, two foliar spray of profenophos 0.05 % at 20 and 40 days after germination to control shoot fly and stem borer pests infesting pearl millet, timely harvesting and threshing. The cumulative effect of technological intervention over five years, revealed average grain yield 4362 kg/ha and dry fodder yield 7365 kg/ha which is 6.17% and 12.76% higher over the farmers’ practices. The economics and cost benefit ratio of both farmers’ and improved practices was worked out. On an average net profit was obtained 6837 /ha due to adoption of improved package of practices. The average cost benefit ratio was 2.23 under improved demonstration practices, while it was 2.43 under farmers’ practices. By conducting the Front line demonstrations of proven technologies, yield potential and net income from pearl millet cultivation can be enhanced to a great extent with increase in the income level of the farming community.

Published: August 2019

Forest measurements, especially in natural forests are cumbersome and complex. 100% enumeration is costly and inefficient. This study sought to find out reliable, efficient and cost-effective sampling schemes for use in tropical rain forest (TRF), moist montane forest (MMF) and dry woodland forest (DWF) in Kenya. Forty-eight sampling schemes (each combining sampling intensity (5, 10, 20, 30%), plot size (25, 50, 100, 400 m2) and sampling technique (simple random sampling, systematic sampling along North-South and along East-West orientations) were generated for testing estimates of forest attributes such as regeneration through simulation using R-software. Sampling error and effort were used to measure efficiency of each sampling scheme in relation to actual values. Though forest sites differed in biophysical characteristics, cost of sampling increased with decreasing plot size regardless of the forest type and attribute. Accuracy of inventory increased with decreasing plot size. Plot sizes that captured inherent variability were 5mx5m for regeneration and trees ha-1 across forest types but varied between forest types for basal area. Different sampling schemes were ranked for relative efficiency through simulation techniques, using regeneration as an example. In many instances systematic sampling-based sampling schemes were most effective. Sub-sampling in one-hectare forest unit gave reliable results in TRF (e.g. SSV-5mx5m-30%) and DWF (e.g. SSV-10mx10m-30%) but not in MMF (5mx5m-100%). One-hectare-complete-inventory method was found inevitable for regeneration assessment in montane forest.

Nowadays the guts malady is one amongst the foremost causes of death within the world. Thus it s early prediction and diagnosing is vital in medical field, which might facilitate in on time treatment, decreasing health prices and decreasing death caused by it. The treatment values the disease is not cheap by most of the patients and Clinical choices are usually raised supported by doctors‟ intuition and skill instead of on the knowledge-rich information hidden within the stored data. The model for prediction of heart disease using a classification techniques in data mining reduce medical errors, decreases unwanted exercise variation, enhance patient well-being and improves patient results. The model has been developed to support decision making in heart disease prediction based on data mining techniques. The experiments were performed using the model, based on the three techniques, and their accuracy in prediction noted. The decision tree, naïve Bayes, KNN (K-Nearest Neighbors) and WEKA API (Waikato Environment for Knowledge Analysis-application programming interface) were the various data mining methods that were used. The model predicts the likelihood of getting a heart disease using more input medical attributes. 13 attributes that is: blood pressure, sex, age, cholesterol, blood sugar among other factors such as genetic factors, sedentary behavior, socio-economic status and race has been use to predict the likelihood of patient getting a Heart disease until now. This study research added two more attributes that is: Obesity and Smoking.740 Record sets with medical attributes was obtained from a publicly available database for heart disease from machine learning repository with the help of the datasets, and the patterns significant to the heart attack prediction was extracted and divided into two data sets, one was used for training which consisted of 296 records & another for testing consisted of 444 records, and the fraction of accuracy of every data mining classification that was applied was used as standard for performance measure. The performance was compared by calculating the confusion matrix that assists to find the precision recall and accuracy. High performance and accuracy was provided by the complete system model. Comparison between the proposed techniques and the existing one in the prediction capability was presented. The model system assists clinicians in survival rate prediction of an individual patient and future medication is planned for. Consequently, the families, relatives, and their patients can plan for treatment preferences and plan for their budget consequently.

The brewing industry generates large amounts of wastewater which are released into surface water after treatment. The aim of this study is to evaluate the performance of the anaerobic treatment of brewery wastewaters in a UASB bioreactor containing activated sludge. After six-weeks operation, 30 samples were taken. Physicochemical analyzes were carried out on activated sludge (T, pH, VFA) and raw and treated waters (T, pH, AT, CAT, TSS, and COD). These analyzes showed that the conditions of the environment were favorable to an optimal growth of the bacteria: temperatures and pH were mostly mesophilic. the ionization of VFA was continuous and their concentration increased at the exit of the bioreactor thus revealing a significant conversion of organic materials by bacteria. The average values ​​of the physicochemical parameters of the raw and treated wastewaters respectively increased from 31.5°C to 35°C for the temperature, from 8.9 to 7.5 for the pH, to 5.54 mg/l at 0 for AT, from 12.35 mg/l to 3.45 mg/l for TAC, from 234.08 mg/l to 129.61 mg/l for TSS and from 1637 mg/l to 282, 46 mg/l for COD. The effectiveness of the treatment allowed a COD reduction ranging from 70 to 94%.

Published: August 2019

AbstractObjectiveThis paper presents the first study where a dynamic neck brace was used to characterize the head motion of ALS patients while concurrently recording the surface electromyography (EMG) of the neck muscles.MethodsEleven ALS patients and 10 age‐matched healthy controls consented and participated in an experiment. Each participant was asked to perform three single‐plane motions of the head‐neck that included flexion–extension in the sagittal plane, lateral bending in the coronal plane, and axial rotation in the transverse plane. Each motion was performed in a cycle and was repeated five times at self‐selected speeds.ResultsDuring single‐plane flexion–extension under gravity, compared to healthy peers, ALS patients showed a shorter duration to reach the maximum flexion and an earlier EMG onset in the neck extensors starting from the neutral. The brace measures in activation of the neck muscles in ALS patients were well correlated with clinically measured scores, such as the ALSFRS‐r and the FVC. The activation duration of sternocleidomastoid, used to rotate the head, correlated well with the ALSFRS‐r and FVC in ALS patients during axial rotation.InterpretationThe ability to synchronously activate a pair of muscles to execute single‐plane motions in ALS patients seems to have been compromised due to the disease and potentially results in head drop. The neck brace measures can be adapted in the clinic to complement self‐reporting in ALS patients and used to assess the head drop and progress of the disease.

Published: August 2019

AbstractWe report sleep phenotypes and polysomnographic findings in two siblings with a novel homozygous variant of the GLRA1 gene causing hereditary hyperekplexia (HH). Both sisters had startles during wakefulness and sleep, sleep terrors, and one had symptoms of REM sleep behavior disorder (RBD). Frequent startles were found in NREM sleep associated with NREM parasomnias in deep sleep. In REM sleep, both had motor behaviors and increased phasic/tonic muscle activities confirming RBD. Clonazepam improved startles, motor behaviors, and muscle activities in REM sleep. Impaired glycinergic transmission in human HH could be involved in the pathophysiology of RBD and NREM parasomnias.
