AbstractHydrogenation reactions are a major route of electron and proton flow on Earth. Interfacing geology and organic chemistry, hydrogenations occupy pivotal points in the Earth’s global geochemical cycles. Some examples of hydrogenation reactions on Earth today include the production and consumption of methane in both abiotic and biotic reactions, the reduction of protons in hydrothermal settings, and the biological synthesis and degradation of fatty acids. Hydrogenation reactions were likely important for prebiotic chemistry on the early Earth, and today serve as one of the fundamental reaction classes that enable cellular life to construct biomolecules. An understanding and awareness of hydrogenation reactions is helpful for comprehending the larger web of molecular and material inter-conversions on our planet. In this brief review we detail some important hydrogenation and dehydrogenation reactions as they relate to geology, biology, industry, and atmospheric chemistry. Such reactions have implications ranging from the suite of reactions on early Earth to industrial applications like the production of hydrocarbon fuel.

Purpose: to evaluate the efficiency of simultaneous topography-guided photorefractive keratectomy (PRK) with accelerated collagen cross-linking in the treatment of stage I keratoconus.Material and methods. 38 patients (49 eyes) aged 18 to 44 with stage I keratoconus were treated with simultaneous topography-guided PRK combined with accelerated corneal collagen crosslinking. Along with standard ophthalmological testing, patients underwent aberrometry, confocal microscopy, optical coherence tomography of the cornea, imaging of the anterior eye section on a Scheimpflug analyzer, and examination of the biomechanical properties of the cornea. The follow-up period was 2 years.Results. Two years after surgery, uncorrected visual acuity which originally was 0.23 ± 0.03 showed a statistically significant increase and reached 0.72 ± 0.02; best corrected visual acuity improved from 0.44 ± 0.03 to 0.89 ± 0.02; the refractive power of the cornea fell from 45.03 ± 0.28 to 42.55 ± 0.31 D; the spherical component of refraction reduced from -2.00 ± 0.19 to -0.73 ± 0.09 D; the cylinder component reduced from 2.46 ± 0.14 to 0.79 ± 0.07 mm, the thinnest point of the cornea reduced from 486.30 ± 4.78 to 406.80 ± 6.51 μm. The highest order aberrations showed the following results: Coma index reduced from 0.27 ± 0.12 to 0.08 ± 0.07, Tilt reduced from 0.53 ± 0.11 to 0.10 ± 0,09, and Trefoil reduced from 0.13 ± 0.04 to 0.05 ± 0.02.Conclusion. The analysis of clinical and functional results, biomechanical properties and structures of the cornea confirmed the efficacy and safety of the combined treatment of patients with stage I keratoconus.

Published: December 2019

AbstractIn this paper, an investigation on the temporal variability of seasonal and annual rainfall in the Calabria region (southern Italy) was carried out using a homogeneous and gap-filled monthly rainfall dataset of 129 rain gauges in the period 1951–2006. In particular, possible trends have been assessed by means of the Innovative Trend Analysis (ITA) technique, which allows the identification of a trend in the low, medium and high values of a series. Moreover, the results obtained with the ITA have been compared with the ones obtained with the Mann–Kendall test. These analyses have been performed in five rainfall zones (RZs) of the study area, characterized by different climatic conditions. As a result, both the methods evidenced a negative trend of the annual rainfall in the entire study area. On a seasonal scale, this negative tendency has been confirmed in autumn and winter although with some differences among the several RZs.

AbstractDespite many water, sanitation, hygiene (WASH) and other environmental health challenges in sub-Saharan Africa, little is known about interactions involving scientists, journalists and the public to aid public understanding of the relationship between WASH and health. Using purposive sampling, we conducted key informant interviews and focus group discussions with scientists, journalists and members of the public in Ghana and Uganda to identify issues associated with the promotion of public engagement with WASH and other environmental health issues. An inductive thematic analysis was used to explore the evidence, challenges and opportunities of public engagement. The effectiveness of public engagement was constrained by poor interactions between scientists and journalists and limited understanding among the public on WASH and other environmental health issues. Challenges identified included inadequate scientists–journalists collaborations, scientists' lack of time, pressure from media organizations and concerns about journalists' inadequate capacity to communicate environmental issues due to lack of training. Possible solutions included increased interactions, science communication training and using public information officers as knowledge brokers between scientists and journalists to boost public engagement with WASH and other environmental health issues. Our study contributes to the literature on the need to actively engage the public with WASH and other environmental health concerns.

Published: December 2019

ABSTRACT

Objectives
To test the null hypothesis that there is no difference in bone dehiscence formation before and after orthodontic tooth movement through an atrophic alveolar ridge.

Material and Methods
This longitudinal retrospective study evaluated pretreatment and posttreatment cone-beam computed tomography imaging of 15 adult patients. Twenty-five teeth were moved through the atrophic alveolar bone, whereas 25 teeth not subjected to translational movement were considered controls. The distances between the cementoenamel junction and the alveolar bone crest were assessed at the mesial, distal, buccal, and lingual surfaces of all of these teeth. Data were compared using the Wilcoxon test. The Spearman correlation test and multivariate linear regression analysis were also performed.

Results
In general, crestal bone height was reduced around 0.5 mm in all groups in every direction. Median buccal dehiscence increased significantly (+2.25 mm) (P &lt; .05) in teeth moved through the atrophic ridge. Control teeth also had buccal crest loss (+0.83 mm), but this was not statistically different from that of the experimental teeth. Lingual dehiscence increased significantly for the experimental (+0.17 mm) and control (+0.65 mm) groups. Mesial bone height decreased more in the control group (–0.44mm) than in the experimental group (–0.14mm). There was moderate correlation between amount of tooth movement and alveolar bone loss.

Conclusions
The null hypothesis was rejected as dehiscence increased after tooth movement through an atrophic alveolar ridge, mainly in the buccal plate.

Introduction. Studies on the effects of hyperbaric oxygenation have often been represented as animal model experiments. Currently, the number of studies on the use of hyperbaric oxygen therapy in the post-transplant period in humans is growing. The need in investigating the efficacy of hyperbaric oxygen therapy in the postoperative period in female transplant patient with tumors of the reproductive system is dictated by time.The aimof the study was to evaluate the efficacy of hyperbaric oxygen therapy in the complex treatment of transplant patients at an early stage of the postoperative period.Material and methods. We have studied the course of an early postoperative period in 8 female transplant patients with reproductive system tumors treated in N.V. Sklifosovsky Research Institute for Emergency Medicine, using hyperbaric oxygenation. The hyperbaric oxygen therapy sessions were provided in a single-patient hyperbaric chamber at 1.2–1.6 ATA for 40 minutes. The status of the redox homeostasis system was assessed based on the data of the platinum electrode open circuit potential measured in blood plasma by using the potentiometric method; and the blood plasma antioxidant activity was assessed by cyclic voltammetry.Results. The analysis of the results showed that there was a direct relationship indicating the positive effect of hyperbaric oxygen therapy on the balance status of the pro- and antioxidant systems of the body, and on the improvement of blood counts.Conclusion. The early inclusion of hyperbaric oxygen therapy in the complex treatment of transplant patients with tumors of the reproductive system contributes to a more rapid recovery of pro- and antioxidant systems of the body, blood counts.

Published: December 2019

Setiap yang bernyawa pasti akan mati, yang tidak diketahui waktu kedatangannya karena menjadi rahasia Ilahi. Karenanya setiap umat manusia dituntut untuk senantiasa mempersiapkan diri menghadapinya. Jika manusia sudah mati, maka jasadnya disebut dengan jenazah atau mayat. Di antara persiapannya adalah manusia harus mampu memandikan dan mengafaninya. Dari kenyataan yang terjadi akhir-akhir ini banyak manusia termasuk di antaranya mahasiswa pendidikan Guru Madrasah Ibtidaiyah UIN Suska Riau ditemukan banyak yang tidak mampu dalam memandikan dan mengafani jenazah, karena ketakutannya akan dibayang-bayangi oleh jenazah, bisa diupahkan kepada orang lain, dan persoalan lainnya yang menyebabkan mereka kurang atau tidak mampu memandikan dan mengafani jenazah. Kondisi itu bagaikan penyakit yang mewabah tidak hanya di masyarakat perkotaan tetapi juga di pedesaan. Padahal Islam menganjurkan bahwa dalam pelaksanaannya lebih afdhal dilaksanakan oleh anggota keluarga jenazah sendiri. Dengan adanya pelaksanaan pelatihan memandikan dan mengafani jenazah bagi mahasiswa PGMI UIN Suska Riau, diharapkan mereka mampu melaksanakannya sekaligus menjadi refleksi social mereka terhadap lingkungannya dimana mereka berada.

Abstract
This article focuses on jewellery made by the Kuchi people, which is still one of the marginalized topics. It presents the best-known types of Kuchi jewellery, the way it is worn, the most commonly used materials for its production and the most utilized jewellery techniques. With respect to the date of origin, the focus is mainly on the second half of the 20th century, but also on the present, with regard to the growing trade in these types of jewellery. For a more comprehensive illustration of design, material and jewellery techniques, a collection of jewellery from the 20th century and the present from the collections of the Náprstek Museum in Prague and a private collection was examined. The X-ray fluorescence (XRF) spectroscopy was used to find out the elemental composition of the materials used in the making of the jewellery.
