Kaolinite-to-Chlorite Conversion from Si,Al-Rich Fluid-Origin Veins/Fe-Rich Carboniferous Shale Interaction

The kaolinite-to-chlorite conversion is one of the chloritization processes that occurs in low temperature diagenetic and hydrothermal systems. The mechanism of this mineralogical transformation is still under discussion, since direct transformation, conversion via berthierine as intermediate phase or direct formation of berthierine/chlorite mix, either by dissolution-crystallization or by solid state transformation (or a combination of both), are all hypotheses put forward. In this context, each description of a kaolinite-to-chlorite conversion occurrence becomes an opportunity to shed new light and to renew this debate. Studying Carboniferous shale–crosscut by large quartz-kaolinite veins–from the mining basin of the North of France, we report therefore an uncommon kaolinite-Fe-rich chlorite assemblage. This assemblage appears as a chlorite fringe 20 µm wide along the interfaces between the shale and the quartz-kaolinite veins. All petrographical, mineralogical and chemical data suggest that the Fe-chlorite results from the interaction between the shale, providing the Fe,Mg supply, and the Si,Al-rich veins, leading to the chloritization of the kaolinite at a small scale via at least one dissolution-recrystallisation step. High-resolution observations highlight that neoformed Fe-rich chlorite contains some 7Å isochemical layers, as relict of berthierine. Therefore, we advance that the conversion takes place either through the precipitation of berthierine following by a second step involving solid state berthierine-chlorite conversion, or through the direct precipitation of a chlorite-rich/berthierine-poor mix driven by the Fe/(Fe + Mg) ratio, at low temperature and in reducing conditions. The comparison of our data with the recent literature allows to prefer the second hypothesis.
Disaster management and preventive conservation in cultural heritage: Konya Archaeology Museum case

ABSTRACT This study focuses on the first stage of the disaster management cycle in cultural heritage, including risk preparedness and preventive conservation. The main objective is to develop a systematic approach to evaluate and investigate old museum buildings in the pre-disaster stage. Konya Archaeology Museum was chosen as a case study to test the applicability of this systematic approach, mainly the RE-ORG model and Visual Pre-assessment Method: UNI EN 16096 (2012. Standard for Condition Survey and Report of Built Cultural Heritage. https://www.en-standard.eu/csn-en-16096-conservation-of-cultural-property-condition-survey-and-report-of-built-cultural-heritage) was used to develop preventive conservation measures against the risks before they turned into damage. Thus, the magnitude of risks was determined and their prioritization was done for building and components.
Association of serum ferritin with insulin resistance in women with polycystic ovarian syndrome

Background: Emerging scientific evidence has disclosed unsuspected influences between iron metabolism, insulin resistance and type 2 diabetes. Even mildly elevated body iron stores are associated with statistically significant increases in glucose homeostasis indices. But till now high serum ferritin associated with type 2 diabetes is not recognized as an entity in the current clinical guidelines for the management of type 2 diabetes.Methods: This was a Cross sectional study carried out from September 2016 to March, 2017 at PCO clinic of infertility outpatient department (OPD), department of obstetrics and gynecology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. The study population consisted of all the diagnosed PCOS patients. Purposive sampling Main outcome variable: serum ferritin level and insulin resistance index (Homeostatic model assessment of insulin resistance: HOMA-IR). Results: Most of the (90.9%) patients were aged 20-30 years having BMI >25 kg/m2, mostly overweight (52.53%) or obese (25.25%). Significant increase of serum ferritin level (72.89±34.97; p=0.001) was noted in PCOS patients with insulin resistance. Marked increase in serum ferritin (82.81±31.57, p<0.001), fasting serum insulin (16.39±7.1; p<0.001), HOMA-IR (3.51±1.55; p<0.001) and more cases with insulin resistance (78.3%; p<0.001) were found in women with high ferritin level (when ≥45.5 ng/ml). Statistically significant strong positive correlation between serum ferritin level and fasting insulin level (r=0.528; p<0.001) as well as HOMA-IR (r=0.492; p<0.001) were observed.Conclusions: These results demonstrated that elevated level of serum ferritin was associated with insulin resistance in PCOS women.
Tree characteristics, microhabitat and edge effect in plantations govern European Turtle-dove Streptopelia turtur nest habitat selection at the edge of Sahara: implications for conservation of a vulnerable species

Summary Tree characteristics, microhabitat, and human presence were measured around nest trees (n = 92) and non-nest trees (n = 92) to identify the best predictors of the European Turtle-dove Streptopelia turtur nest occurrence in date palm plantations of the Biskra region (Algeria). Nest occurrence was (i) positively influenced by the height of trees and that of the herbaceous layer, and (ii) quadratically affected by diameter at breast height (DBH), the cover of trees, the cover of the herbaceous vegetation, and the distance to the edge of date palm plantation. Variation partitioning analysis revealed that the pure effect of tree physical characteristics (tree height and DBH) was robust in explaining the occurrence of Turtle Dove nests (adj. R2 = 0.52, P = 0.001). For an efficient management of this Saharan population, special attention should be paid in the short term to keeping high date palm trees while ensuring, in the medium and long term, the presence of different-sized palm tree classes at each exploitation. There is no doubt that date palm plantations of Biskra are of paramount importance because they offer good opportunities for consolidating and improving the knowledge on this threatened species and other species at the Sahara edge.
Development of Multiple Injection Channels During a Sawtooth Substorm Event

Substorm injection boundary was proposed to explain the dispersion characteristics of particles during the substorm expansion phase. Sawtooth event, a peculiar quasi‐periodic type of substorms, is believed to have a very wide injection boundary around the geosynchronous orbit. In this study, we combine the numerical simulation of the Rice Convection Model with the IMAGE, LANL, and GOES data to investigate how the injection develops and couples with the ionosphere during a sawtooth substorm. We find the wide injection breaks up into multiple injection boundaries/channels with the local time separation of about 1–2 h. Using backward tracing of energetic particles in the self‐consistently computed electromagnetic field, we can infer the MLT locations of the channels, which are found to be nearly one‐to‐one co‐located with multiple finger‐like auroral structures. Our study provides strong evidence that the interchange instability plays a central role in the development of multiple injection channels.
Exchange and Communal Strengths’ Associations With Relational Characteristics and Forgiveness

Clark and Mills (2012) proposed that communal norms characterize “healthy marriages,” whereas exchange norms indicate “troubled” ones. Using the actor–partner interdependence model, we consider this proposal. Heterosexual married partners’ exchange and communal strength are examined with several relational features including trust, commitment, relational satisfaction, and control mutuality, as well as partner-specific tendencies toward forgiveness. The findings indicate that one’s communal strength is associated with positive relational features for both oneself and one’s spouse, as well as a greater propensity to forgive and lesser tendencies toward negative forgiveness (retaliation). Exchange strength was generally associated with negative forgiveness. However, the relationship between exchange strength and relational features is more complicated. Lesser communal strength was generally associated with lower levels of the relational characteristics. Yet, exchange and communal strength interacted, indicating exchange may play a protective function by buffering against the ill effects of a lack of communal strength for some relational characteristics.
Correlation of amniotic fluid index with fetomaternal outcome

Background: Amniotic fluid acts like a protective cover around the baby. Advances in ultrasound have increased early detection of abnormal amniotic fluid volumes. Any variation in the amniotic fluid volume warrants antenatal foetal surveillance.Methods: 300 pregnant women between 37 to 40 weeks of gestation were included in the study. A detailed history, examination and ultrasound was done. Pregnant women were divided into 3 groups’ i.e. normal liquor, oligohydramios and polyhydramnios. All the women were closely monitored during labour and puerperium. Follow-up was done till 7 days post-delivery. Maternal and neonatal data were collected.Results: 300 pregnant women were included in the study, out of which 221 had normal amniotic fluid index (AFI), 64 had oligohydramnios and 15 had polyhydramnios. All baseline characteristics were comparable between the groups except body mass index (BMI). Incidence of meconium stained liquor was significantly higher in oligohydramnios compared to normal AFI and polyhydramnios groups (34.4% versus 10.5% versus 13.3%; p=0.0001). Caesarean section rates were significantly higher in polyhydramnios and oligohydramnios compared to normal AFI group (73.3% versus 70.3% versus 19.9%; p=0.0001). Higher cases of low birth weight were recorded in oligohydramnios group compared to normal AFI and polyhydramnios group group (32.8% versus 18.6% versus 13.3%; p=0.011). Neonatal intensive care unit (NICU) admissions were higher in oligohydramnios (35.9%) and polyhydramnios (33.3%) compared to normal AFI group (35.9% versus 33.3% versus 12.7%; p=0.0001). Conclusions: Abnormal liquor volumes are associated with increased caesarean section rates, NICU admissions and neonatal mortality. Careful assessment of pregnant women is imperative for proper counselling and management.
Corporate social responsibility and firm performance: The moderation of investment horizon and corporate governance

Abstract The current study proposes an integrated theoretical frame work, to explain the moderating role of institutional investors, their investment horizon and corporate governance mechanism in the sustainability of corporate social responsibility (CSR) and firm’s performance nexus. The proposed model explains how, the positive association between CSR and firm performance relationship, established on the basis of the stakeholder and corporate citizenship theories, can be further strengthened (effective monitoring hypothesis) or weakened (myopic institutions theory) by the presence of institutional investors in the firm’s ownership structure and corporate governance mechanism (agency theory). The study tested the proposed model on the unbalanced sample of 327 non-financial firms listed on the Pakistan stock exchange (PSX). The study concludes that, based on the agency theory, institutional investors (as a homogeneous group) positively moderates the CSR and firm performance relationship. However, agency theory failed to explain the negative moderation of short term investment horizon institutional investors and firm performance. The study further confirms the agency role of effective corporate governance mechanism in the sustainable CSR and firm performance relationship. The current study explored some of the major theoretical contradictions in the field of corporate finance literature, which are puzzling for the practitioners and scholars.
Fused Filament Fabrication Three-Dimensional Printing Multi-Functional of Polylactic Acid/Carbon Black Nanocomposites

Conductive Polymer Composites (CPCs) have recently gained an extensive scientific interest as feedstock materials in Fused Filament Fabrication (FFF) Three-dimensional (3D) printing. Polylactic Acid (PLA), widely used in FFF 3D printing, as well as its Carbon Black (CB) nanocomposites at different weight percentage (wt.%) filler loadings (0.5, 1.0, 2.5 and 5.0 wt.%), were prepared via a melt mixing filament extrusion process in this study and utilized to manufacture FFF 3D printed specimens. The nanocomposites were examined for their electrical conductivity. The highest loaded 3D printed CPC (5.0 wt.%) was tested as an electrothermal Joule heating device. Static tensile, flexural, Charpy’s impact and Vickers microhardness mechanical properties were investigated for the neat and PLA/CB 3D printed nanocomposites. Dynamic Mechanical Analysis (DMA) revealed a stiffening mechanism for the PLA/CB nanocomposites. Scanning Electron Microscopy (SEM) elucidated the samples’ internal and external microstructural characteristics. The PLA/CB 5.0 wt. % nanocomposite demonstrated also antibacterial properties, when examined with a screening process, against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). It can be envisaged that the 3D printed PLA/CB CPCs exhibited a multi-functional performance, and could open new avenues towards low-cost personalized biomedical objects with complex geometry, amongst others, i.e., surgery tools, splints, wearables, etc.

Avalanche danger level characteristics from field observations of snow instability

Abstract. Avalanche danger levels are described in qualitative terms that mostly are not amenable to measurements or observations. However, estimating and improving forecast consistency and accuracy require descriptors that can be observed or measured. Therefore, we aim to characterize the avalanche danger levels based on expert field observations of snow instability. We analyzed 589 field observations by experienced researchers and forecasters recorded mostly in the region of Davos (Switzerland) during 18 winter seasons (2001–2002 to 2018–2019). The data include a snow profile with a stability test (rutschblock, RB) and observations on snow surface quality, drifting snow, signs of instability and avalanche activity. In addition, observers provided their estimate of the local avalanche danger level. A snow stability class (very poor, poor, fair, good, very good) was assigned to each profile based on RB score, RB release type and snowpack characteristics. First, we describe some of the key snowpack characteristics of the data set. In most cases, the failure layer included persistent grain types even after a recent snowfall. We then related snow instability data to the local avalanche danger level. For the danger levels 1–Low to 4–High, we derived typical stability distributions. The proportions of profiles rated poor and very poor clearly increased with increasing danger level. For our data set, the proportions were 5 %, 13 %, 49 % and 63 % for the danger levels 1–Low to 4–High, respectively. Furthermore, we related the local avalanche danger level to the occurrence of signs of instability such as whumpfs, shooting cracks and recent avalanches. The absence of signs of instability was most closely related to 1–Low and the presence of them to 3–Considerable. Adding the snow stability class and the 3 d sum of new snow depth improved the discrimination between the lower three danger levels. Still, 2–Moderate was not well described. Nevertheless, we propose some typical situations that approximately characterize each of the danger levels. Obviously, there is no single easily observable set of parameters that would allow us to fully characterize the avalanche danger levels. One reason for this shortcoming is the fact that the snow instability data we analyzed usually lack information on spatial frequency, which is needed to reliably assess the danger level.
Pseudomonas aeruginosa 1244 Piliation: Environmental Signals and Regulation

The presence of Pseudomonas aeruginosa 1244 pili on the bacterial surface is dependent upon the growth environment. Quantitative western immunoblot analysis showed that an agar plate promoted surface expression of pili, whereas bacterial cells grown in liquid broth lacked similar appendages. Hyperexpression of the pilA gene increased piliation in broth cells but not to the extent of plate cells. Real-time RT-PCR indicated that the pilA gene has the potential to be regulated posttranscriptionally, regardless of the growth environment. The P. aeruginosa 1244 pilin glycan and lipopolysaccharide O-antigen are synthesized via the same biosynthetic pathway. Rabbits immunized with LPS-free pili produced antibodies that recognized both pili and LPS. Serum from these animals was analyzed using ELISA assays, and the pilin glycan was found to be an important immunogenic epitope directing strong responses against both the glycan and O-antigen. This could prove useful in P. aeruginosa vaccine generation.
Interactions Sol-Plante dans un contexte de phytomanagement de sols pollués par des métaux : application à Miscanthus x giganteus

Alentours de l'ancienne fonderie de Pb Metaleurop Nord, Miscanthus x giganteus a accumule peu de Pb et Cd dans ses organes aeriens. Les experiences ont ete menees pour evaluer la capacite de la plante a ameliorer la fonctionnalite des sols contamines, etudier les impacts a long terme des debris de feuilles massives sur le systeme sol-plante et determiner les impacts des contaminants sur la sante de la plante en premiere et deuxieme annees de culture. Cinq sols ete echantillonnes a differentes distances de la fonderie. Le plus loin est situe a 75 km. Trois cultivars ete utilises. Les resultats ont confirme la tolerance des plantes aux metaux, et montre des effets positifs de la culture sur les activites biologiques du sol. Une tendance favorable ete notee pour la teneur en carbone organique et la capacite d'echange de cations. L'incorporation de debris a conduit une evolution favorable de certains parametres physicochimiques et biologiques. Sur une periode de trois a six mois apres l'addition, aucun effet n'a ete observe sur l'extrabilite, la phytodisponiblite de Cd et Pb et la sante d'une culture modele (raygrass). En outre, les resultats des biomarqueurs du stress de la premiere recolte demontre l'existence d'un stress oxydatif aux miscanthus cultives sur le sol avec plus de 500 mg Pb kg-1. A la fin de la deuxieme annee, le stress oxydatif etait plus present et apparaissait sur les plantes dans le sol avec plus de 200 mg Pb kg-1. Cela s'explique par les contraintes des conditions experimentales (la culture dans les conteneurs souligner les interactions entre les metaux et le systeme racinaire). Enfin, aucune difference n'a ete observee entre les cultivars etudies.
[Intraepithelial capillary hemangioma?].

INTRODUCTION Histological examination of a biopsy of a lesion of the glans penis revealed blood capillaries within the malpighian epithelium. CASE REPORT A 66 year-old man exhibited two circumscribed red plaques of the glans penis following posthectomy. Their histological examination revealed blood capillaries within the epithelium without basal membrane and pericytes between the endothelial cells and keratinocytes. Further evolution was towards lichen planus of the genital mucous membranes. In spite of a verrucous carcinoma which had been surgically removed, the evolution within a follow-up time of 6 years was favorable. DISCUSSION Blood capillaries ascending in the epithelium of the genital mucous membranes have been observed in a special variant of Zoon's balanitis, the lichenoid, telangiectatic and purpuric balanitis described by Jonquières in 1971. In our patient exhibiting a lichen planus of the glans penis, the occurrence of blood vessels in the malpighian layer of the epithelium may be interpreted as the consequence of an unusual epithelial and vascular regeneration of an erosive lichenoid lesion. It may also be interpreted as an original neoplasia, and could therefore be considered as a genital intraepithelial capillary hemangioma.
Predicting repeat usage intention towards O2O food delivery: extending UTAUT2 with user gratifications and bandwagoning

ABSTRACT This study examines the antecedents to repeat usage intentions (RUI) of online-to-offline (O2O) food delivery (OFD) services using an integrated framework of Uses and Gratification Theory (UGT) and Unified Theory of Adoption and Usage of Technology 2 (UTAUT 2). Considering the increasing influence of online review(s) (ORVs) and online rating(s) (ORTs) in e-commerce, their moderation effect on the satisfied consumers’ RUI has also been examined. Partial Least Squares-Structural Equation Modeling (PLS-SEM) has been applied to assess the hypotheses and structural model. The analysis of the data collected through an online survey of 532 respondents from two tier-II cities revealed that delivery experience (DE) and time-saving orientation (TSO) are the gratifications critical to OFD usage intentions (UI). While performance expectancy (PE), effort expectancy (EE), facilitating conditions (FC), and hedonic motivations (HM) affected e-satisfaction (e-SAT), the e-SAT and UI significantly affected RUI. The negative moderation impact of bandwagoning on satisfied consumers’ RUI reflects discrepancies in posted ORTs/ORVs and personal experience. Relevant managerial inferences will help OFD service providers adjust strategies to make OFD services more sustainable and consumer-centric. This study makes several theoretical contributions as well.
