BACKGROUND: Direct implantation of metallic drug-eluting stents is recommended for lesions with high thrombotic burden; however, this can't be applied to bioresorbable scaffold for which adequate lesion preparation is recommended.
AIM: We aimed at assessing the feasibility and safety of direct scaffold implantation based only on angiographic assessment in patients presented with non-ST segment elevation acute coronary syndrome.
METHODS: The study was a retrospective two-centre study conducted over patients diagnosed with NSTE-ACS presented to cardiology department at Juan Ramon Hospital, Spain and critical care department, Cairo University in the period between February 2016 to May 2017. We included patients for whom we depend only on angiographic assessment for decision making whether to directly implant the scaffold or predilate the lesion and we excluded patients for whom intracoronary imaging was used at the index procedure either for pre or post-implantation. The primary outcome of interest was the device-oriented composite endpoints (DOCE) including cardiac death, and MI attributed to the target vessel and TLR. The secondary endpoints were the broader patient-oriented composite outcome (POCE) and scaffold/stent thrombosis. POCE includes all-cause mortality, any MI and any revascularisation (including TLR, TVR and revascularisation of non- target vessel)
RESULTS: Among 46 patients with NSTE-ACS treated with BVS, we did direct implantation in 20 patients (group A), and we used pre dilatation in 26 patients (group B). The two groups have similar demographics and clinical criteria. Procedural success was obtained in all study population. Mean follow up duration was 12 months. We have total of 10% device-oriented composite endpoints in group A versus 15% in group B (p-value = 0.684). We didn’t document any cardiac death in both groups. In group B we had one (3.8%) non-fatal MI while there was no MI in group A (P-value = 1). In group A we had 2 cases (10%) of TLR while in group B there were 3 cases (11.5%) TLR (P-value = 1). We have two cases (7.7%) of TVR in group B and one in group A p-value = 1. All cases were planned staged PCI. Scaffold thrombosis occurred in one case in group A (5%) and two cases in group B (7.7%) p-value = 1.
CONCLUSION: With proper lesion selection, direct BVS implantation in all-comers NSTE-ACS patients is feasible and safe even without the aid of intracoronary imaging.

Authors: Tripp Alice , Tollefson Nona
Published: September 2019

ABSTRACT

Differences in item difficulty between conventional and complex multiple-choice (M-C) items measuring objectives written at the six levels of the cognitive domain and three content areas within a basic health professions subject matter area were investigated. Conventional and complex M-C items were also compared in terms of item discrimination.

Five hundred fifteen senior baccalaureate nursing students randomly responded to one of two packages of 18 oneitem pharmacology achievement tests. Items in the two packages were matched in all respects except for the type of option.

A 2 × 3 × 6 repeated measures ANCOVA with method of pharmacology as the covariate showed a statistically significant (p < .01) interaction of option × content × cognitive level. Scheffé tests revealed that complex items were more difficult than conventional option items at the knowledge level only across all content areas investigated. No statistically significant differences were found between the two option types discriminating ability.

Results of this research question the validity of the assumption that complex items are more difficult and discriminating than conventional M-C items.

Published: September 2019

Background Panic disorder is a complex disease of unclear etiology but with an apparent genetic component. PDE4B gene product is involved in many cell processes owing to its function-regulation of the level of a second messenger cAMP. PDE4B gene polymorphism has been shown to be associated with some mental disorders including panic disorder.

Aims The goal of our study was to evaluate the role of 3 SNPs in the PDE4B gene in the development of panic disorder.

Methods 94 patients diagnosed with panic disorder according to the DSM-IV criteria were enrolled in the study. The population control group included 192 subjects. Genotyping was carried out by real-time PCR with TaqMan probes.

Results The investigated substitutions are not associated with panic disorder in general and in female/male cohorts (p > 0.05). The analysis of complex genotypes demonstrated two protective complex genotypes (rs1040716:A, T + rs10454453:A + rs502958:A and rs1040716:A, T + rs502958:A) associated with panic disorder in general regardless of the patient's gender (p < 0.05). These genotypes did not correlate with the patient's sex.

Conclusions We found two complex protective genotypes associated with panic disorder. This can be due to the fact that predisposition to the disease are associated with other genes, while PDE4B gene polymorphism reduces their effect.

Published: September 2019

This study was carried out to investigate the regional variation and effects of shape and color of seeds and sprouts on the content of rutin and quercetin in Tartary buckwheat germplasm. A total of 44 foreign Tartary buckwheat germplasms were examined and compared their rutin and quercetin contents based on the collected countries, seed shape and seed color using high-performance liquid chromatography and spectrophotometry. The results revealed that rutin and quercetin content varied at different regions. Rutin content in seed (1326.5 mg/100 g) and sprouts (5440.4 mg/ 100 g) of the accession collected from Nepal area was higher than any accession collected from other regions. In seeds, the quercetin content showed the highest value (22.5 mg/100 g) from Pakistan whereas sprouts showed the highest quercetin content (392.0 mg/100 g) from China. However, the quercetin content in sprout was 4~90 times higher than that of seeds. Taken together, the present study suggests that sprouts could be used more effectively than seeds in the case of quercetin, and strains from Nepal, Bhutan, China, and Japan have a high potential material to use seed and sprouts for buckwheat industry in making functional food and medicine.Received: April 29, 2019; accepted: June 15, 2019Keywords: Tartary buckwheat; seed; sprout; germplasm; rutin; quercetin
The Gold Boom in Sudan
Authors: Chevrillon-Guibert Raphaëlle
Published: September 2019

The loss of oil revenues from South Sudan, which became independent in 2011, together with the global decline in oil prices, plunged Sudan into a dramatic economic crisis. In the 2000s, the concomitant increase in the prices of minerals, particularly of gold, led to a renewed interest in mining on the part of the Khartoum regime. This article details the strategies deployed by the Sudanese government to turn mining activities into a lifeline, in particular by encouraging the development of industrial production and reorganizing the gold trade sector. To highlight the implications of these new economic policies on power relations between State and society, as well as relationships between the different regions of the country, my study also analyses how different economic players have responded to the new opportunities and constraints created. It is based on fieldwork conducted in Khartoum and Nile Valley State in April 2014, June 2015, April and November 2016.
Risk Attitudes and Financial Profitability of Tomato Farmers - A Study in Bangladesh
Authors: Mitra S. , Sharmin S.
Published: September 2019

Purpose: Tomato production in the world has increased tremendously within last few decades. Nevertheless, tomato farmers are facing production, market, price and financial uncertainty. Management of these risks is greatly influenced by their attitudes towards risk. So, the objective of this study is to determine the risk attitude and profitability of tomato farmers in Bangladesh.Research Method: Sixty sample respondents of tomato farmers were selected from Mymensingh district. The Safety-First principle was used to estimate risk attitude coefficient while obit regression model was utilized to estimate the factors affecting risk attitudes of tomato farmers. In addition, financial profitability was analyzed from different points of view.Findings: Most of the tomato farmers were risk averse. Results find that only 18% of  farmers were risk preferring while 42% of farmers were risk averse. Risk preferences of farmers increase with training and education while risk preference decrease with age and experience. Training and education help to understand the importance of receiving newly introduced technology, timely application of seed, irrigation and fertilizer. Education assists to earn from diversified sources that make them risk preferred. The benefit cost ratio (BCR) of tomato farming was 2.31 indicating that tomato farming is profitable.Research Limitation: A small sample size was used for this study. Therefore, policy makers should be cautious to generalize the results to a wide context of tomato farmers in developing countries.Originality/ Value: Productivity and profitability of tomato farmers can be improved if farmers can manage different risks and uncertainty associated with production practices.

Published: September 2019

Ferritin, an iron-binding protein, is composed of two subunits, a heavy chain and a light chain. It regulates many biological functions, such as proliferation, angiogenesis, and immunosuppression. The objective of this study was to determine the expression and distribution of ferritin in the periodontal tissuesof primates.First, we assessed the expression of ferritin in primary cultured cells isolated from human periodontal tissues using the polymerase chain reaction and immunofluorescent staining. Second, we investigated the expression and distribution of ferritin in the periodontal tissues of Macaca fascicularis, human gingival tissues, and human gingival carcinoma tissues using immunohistochemistry.Both protein and mRNA of ferritin were constitutively present in human primary cultured cells, including those from the dental apical papilla, periodontal ligament, dental pulp, and gingival epithelium, as well as gingival fibroblasts. In M. fascicularistissues, the immunohistochemical staining was particularly strong in blood vessel and mineralizing areas of the dental pulp and periodontal ligament. Ferritin heavy chain exhibited specific immunopositivity in in the stratum basale of the epithelium in human gingival tissue and strong immunostaining was found in peripheral regions of gingival carcinoma sites. Ferritin is constitutivelypresent andwidelydistributed in the periodontal tissues of primates. Ferritin may play roles in epithelial proliferation, vascular angiogenesis, and mineralization in these tissues.
Cutaneous wound healing: Current concepts and advances in wound care
Authors: Klein Kenneth C , Guha Somes Chandra
Published: September 2019

A non-healing wound is defined as showing no measurable signs of healing for at least 30 consecutive treatments with standard wound care.[1] It is a snapshot of a patient’s total health as well as the ongoing battle between noxious factors and the restoration of optimal macro and micro circulation, oxygenation and nutrition. In practice, standard therapies for non-healing cutaneous wounds include application of appropriate dressings, periodic debridement and eliminating causative factors.[2] The vast majority of wounds would heal by such approach with variable degrees of residual morbidity, disability and even mortality. Globally, beyond the above therapies, newer tools of healing are selectively accessible to caregivers, for various logistical or financial reasons. Our review will focus on the use of hyperbaric oxygen therapy (HBOT), as used at our institution (CAMC), and some other modalities that are relatively accessible to patients. HBOT is a relatively safe and technologically simpler way to deliver care worldwide. However, the expense for including HBOT as standard of care for recognized indications per UHMS(Undersea and Hyperbaric Medical Society) may vary widely from country to country and payment system.[3] In the USA, CMS (Centers for Medicare and Medicaid Services) approved indications for HBOT vary from that of the UHMS for logistical reasons.[1] We shall also briefly look into other newer therapies per current clinical usage and general acceptance by the medical community. Admittedly, there would be other novel tools with variable success in wound healing worldwide, but it would be difficult to include all in this treatise.

Published: September 2019

Introduction: To optimize the functional and esthetic result of cranioplasty, it is necessary to choose appropriate materials and take steps to preserve and support tissue vitality. As far as materials are concerned, custom-made porous hydroxyapatite implants are biomimetic, and therefore, provide good biological interaction and biointegration. However, before it is fully integrated, this material has relatively low mechanical resistance. Therefore, to reduce the risk of postoperative implant fracture, it would be desirable to accelerate regeneration of the tissues around and within the graft. Objectives: The objective was to determine whether integrating growth-factor-rich platelet gel or supportive dermal matrix into hydroxyapatite implant cranioplasty can accelerate bone remodeling and promote soft tissue regeneration, respectively. Materials and Methods: The investigation was performed on cranioplasty patients fitted with hydroxyapatite cranial implants between 2004 and 2010. In 7 patients, platelet gel was applied to the bone/prosthesis interface during surgery, and in a further 5 patients, characterized by thin, hypotrophic skin coverage of the cranial lacuna, a sheet of dermal matrix was applied between the prosthesis and the overlying soft tissue. In several of the former groups, platelet gel mixed with hydroxyapatite granules was used to fill small gaps between the skull and the implant. To confirm osteointegration, cranial computed tomography (CT) scans were taken at 3-6 month intervals for 1-year, and magnetic resonance imaging (MRI) was used to confirm dermal integrity. Results: Clinical examination performed a few weeks after surgery revealed good dermal regeneration, with thicker, healthier skin, apparently with a better blood supply, which was confirmed by MRI at 3-6 months. Furthermore, at 3-6 months, CT showed good biomimetism of the porous hydroxyapatite scaffold. Locations at which platelet gel and hydroxyapatite granules were used to fill gaps between the implant and skull appeared to show more rapid integration of the implant than untreated areas. Results were stable at 1-year and remain so to date in cases where follow-up is still ongoing. Conclusions: Bone remodeling time could be reduced by platelet gel application during cranioplasty with porous hydroxyapatite implants. Likewise, layering dermal matrix over such implants appears to promote dermal tissue regeneration and the oshtemo mimetic process. Both of these strategies may, therefore, reduce the likelihood of postsurgical fracture by promoting mechanical resistance.

Published: September 2019

Introduction: Mandibular fractures represent approximately two-thirds of all the maxillofacial fractures (nearly 70%) out of which fractures of mandibular angle represent for 26-35%. Aim of the Study: The aim of this study is to compare the transoral and extraoral (submandibular) approaches for fixation of mandibular angle fractures. Objectives of Study: The objectives of the following study are to evaluate ease of accessibility, time taken for the procedure, ease of anatomic reduction and complications. Materials and Methods: A prospective study was carried out in 30 patients reporting to the Department of Oral and Maxillofacial surgery, Narayana Dental College and Hospital, Nellore, Andhra Pradesh during the period of months from November 2011 to August 2013 who were randomly divided in two groups based on computer generated simple randomization chart. Group I patients underwent transoral reduction and fixation and Group II patients underwent extraoral reduction and fixation. The ease of accessibility was analysed by visual analogue scale by the operating surgeon, time taken from incision to closure with digital clock, difficulty level index of surgeon based on the time taken for the procedure and approach related complications. Results: The ease of accessibility in Group I was good in 53.3% while in Group II patients approached extraorally it was good in 86.7%. Group I patients approached transorally showed a mean of 49.7 min while that of Group II patients approached extraorally showed a mean of 73.4 min. Group I had a minimum difficulty level index in 60%, moderate difficulty level in 33.3% and severe difficulty level in 6.7% while Group II had a minimum and moderate difficulty level in 46.7% and severe difficulty level in 6.7%. There was 1 (6.7%) complication reported in each group. Conclusion: The statistical analysis of this study concludes that fracture line starting anterior to mandibular third molar and ending at anteroinferior border of the insertion of the masseter muscle or posterior body of mandible can be approached transorally. Fracture line starting posterior or distal to the third molar or posterior to the insertion of the masseter muscle to the angle of the mandible or fracture line extending high in the ramus, extraoral approach provides a better choice for reduction and fixation of the fractured segments with restoration of anatomical and functional occlusion.

Introduction: As intense pulsed light (IPL) is widely used to treat cutaneous vascular malformations and also used as non-ablative skin rejunuvation to remodel the skin collagen. A study has been undertaken to gauze the effect of IPL on immature burn scars with regard to vascularity, pliability and height. Materials and Methods: This study was conducted between June 2013 and May 2014, among patients with immature burn scars that healed conservatively within 2 months. Photographic evidence of appearance of scars and grading and rating was done with Vancouver Scar Scale parameters. Ratings were done for both case and control scar after the completion of four IPL treatment sessions and were compared. Results: Out of the 19 cases, vascularity, pliability and height improved significantly (P < 0.05) in 13, 14 and 11 scars respectively following IPL treatment. Conclusions: Intense pulsed light was well-tolerated by patients, caused good improvement in terms of vascularity, pliability, and height of immature burn scar.

Published: September 2019

In this single case study, the possible effect of low-level laser therapy (LLLT) was explored in the form of light emitting diodes on a chronic non-healing wound of 6 months duration in an 18-year-old male patient suffering from thalassemia intermedia. After irradiation, with LLLT dosage of 17.3 J/cm 2 for 8 min for 2 weeks duration followed by proliferative dosage of 8.65-4.33 J/cm 2 for 4 min from 3 rd week to 6 th week for 2 min along with antibiotics vancomycin (15 mg/kg) and a combination of amoxicillin and clavulanic acid (1 g). Proliferation of healthy granulation tissue was observed with decrease in score of pressure ulcer scale with complete re-epithelialization eventually LLLT irradiation could be a novel method of treatment for chronic non-healing wound in a thalassemia intermedia patient and an useful adjunct to standard care of treatment of pressure ulcers. It is postulated that LED irradiation augments wound healing with an early closure and no recurrence at the irradiated site even after follow up of 6 months.

Published: September 2019

We present a rare complication of abdominal liposuction: bowel perforation and necrotizing fasciitis. Because of bilateral lumbar hernia, a 56-year-old woman had caecum and descending colon perforation during lipoplasty. She had septic shock syndrome at her admission. The authors treated this complex wound with several debridement, omental flap, NPWT and split-thickness skin graft. The incidence of abdominal wall perforation with visceral injury is 14 in 100,000 liposuctions performed. There are only 12 cases of bowel perforation in literature but this complication is probably underestimated. Prompt surgical debridement is absolutely mandatory in this life threatening scenario. Lumbar hernia is very rare and should be ruled out before every abdominal liposuction clinically or with imaging modalities.

An 83-year-old man presented with an unusually severe case of rhinophyma. Giant rhinopyhma is very rare in literature. The giant lesion was widely excised using sharp surgical incision and coblation assisted surgery. Using direct coblation to the nasal dorsum may cause edema in the surrounding tissue. There was minimal edema in surrounding tissue using this technique. A full thickness-skin graft was applied after excision. Cosmetic and functional postoperative results were satisfactory.
Pedicle streaking: A novel and simple aid in pedicle positioning in free tissue transfer
Authors: Aggarwal Aditya , Singh Hardeep , Mahendru Sanjay , Brajesh Vimalendu , Singh Sukhdeep , Khare Ashish , Kothari Umang , Khazanchi Rakesh Kumar
Published: September 2019

Introduction: The pedicle positioning in free tissue transfer is critical to its success. Long thin pedicles are especially prone to this complication where even a slight twist in the perforator can result in flap loss. Pedicles passing through the long tunnels are similarly at risk. Streaking the pedicle with methylene blue is a simple and safe method which increases the safety of free tissue transfer. Materials and Methods: Once the flap is islanded on the pedicle and the vascularity of the flap is confirmed, the pedicle is streaked with methylene blue dye at a distance of 6-7 mm. The streaking starts from the origin of the vessels and continued distally on to the under surface of flap to mark the complete course of the pedicle in alignment. The presence of streaking in some parts and not in rest indicates twist in the pedicle. Observation and Results: Four hundred and sixty five free flaps have been done at our centre in the last 5 years. The overall success rate of free flaps is 95.3% (22 free flap failures). There has not been a single case of pedicle twist leading to flap congestion and failure. Conclusion: This simple and novel method is very reliable for pedicle positioning avoiding any twist necessary for successful free tissue transfer.
A report of 2 patients with transient blindness following Le Fort I osteotomy and a review of past reported cases
Authors: Mathew Philip , Adenwalla Hirji Sorab , Narayanan Puthucode V , Nyamu Emily
Published: September 2019

Blindness following a LeFort I osteotomy is a rare but extremely serious complication. Ten cases have been reported to date. None of these patients recovered vision. Optic neuropathy is believed to be the cause but the exact mechanism has not been settled. We report the first, and the only two, documented cases of complete loss of vision that recovered subsequently. The first patient was a 19-year-old male with repaired bilateral cleft lip and palate. He developed loss of vision in the right eye on the second postoperative day. The second patient was a 22-year-old male with repaired unilateral cleft lip and palate. He developed complete loss of vision in the left eye on the day of surgery. Both these patients underwent ongoing studies, which did not show any abnormalities. Both were treated with methylprednisolone. Both the patients gradually showed improvement in their vision. The first patient recovered normal vision several months postoperatively. The second patient’s vision improved to 4/60 by 4 months postoperatively. We discuss the probable mechanisms of optic nerve injury and also the possible reasons why sight was restored in these patients. This is a rare but serious complication following a fairly common procedure. Through this article we wish to create an awareness of this complication and also a possible way of avoiding such a disaster.
A simple external tissue expansion technique based on viscoelastic properties of skin to attain direct closure of a large scalp defect: A case report
Authors: Ratnam Bandikatla Venkata
Published: September 2019

Background: Direct closure of large scalp defects is not an easy task. Complicated flap designs or staged surgeries over a period of 6 months are often required. A case of a large scalp defect that was closed directly in 3 months by applying a simple external tissue expansion technique is presented in this report. Patient Profile: A 28-year-old male patient presented with a painful swelling of about 13 cm × 14 cm, on frontoparietal scalp. A biopsy done elsewhere reported it to be a neurofibroma. He sought tumour excision and scalp defect coverage by hair-bearing scalp in a period of less than 5 months. Materials and Methods: The tumour was excised and the adjacent scalp was gradually expanded with the help of an external fixator. The patient had immediate pain relief after excision. The goal of repairing scalp defect and replacing it with hairy scalp was achieved in 3 months. Conclusion: The mechanical device required for this technique is relatively easily accessible. It is not difficult to achieve desirable outcomes, and the same can be applied to large wounds on other areas.

Published: September 2019

Purpose The purpose of this study was to determine the rate and outcomes of pregnancies subsequent to breast cancer in Korea, and the effect of such pregnancies on the prognosis of women who survived breast cancer and subsequently conceived. Materials and Methods We followed a total of 31,761 Korean women 45 years of age or younger who were treated for primary breast cancer from 2002 to 2010. We also included follow-up surveys that were conducted through December 2011. We identified recurrence and mortality from breast cancer using data linked to the Korea National Health Insurance database. We used propensity score matching of the study cohort to analyze the risks of recurrence and mortality from breast cancer depending on pregnancy. Results Within our sample, 992 women (3.1%) became pregnant after receiving treatment for breast cancer. Of those, 622 (67.5%) successfully delivered; the remaining 370 (32.5%) failed to deliver. After propensity score matching, we found that the women who became pregnant after breast cancer did not have a different risk of recurrence (hazard ratio [HR], 0.503; 95% confidence interval [CI], 0.434 to 0.584) and death (HR, 0.520; 95% CI, 0.397 to 0.681), compared with those who did not conceive after breast cancer treatment. Conclusion Our study is the first to report outcomes for Korean women who survived breast cancer and subsequently conceived. Women who survived breast cancer and subsequently became pregnant did not show a poorer survival outcome, compared with those who did not become pregnant.
Polynomials from Combinatorial -theory
Authors: Monical Cara , Pechenik Oliver , Searles Dominic
Published: September 2019

We introduce two new bases of the ring of polynomials and study their relations to known bases. The first basis is the quasi-Lascoux basis, which is simultaneously both a $K$-theoretic deformation of the quasi-key basis and also a lift of the $K$-analogue of the quasi-Schur basis from quasi-symmetric polynomials to general polynomials. We give positive expansions of this quasi-Lascoux basis into the glide and Lascoux atom bases, as well as a positive expansion of the Lascoux basis into the quasi-Lascoux basis. As a special case, these expansions give the first proof that the $K$-analogues of quasi-Schur polynomials expand positively in multifundamental quasi-symmetric polynomials of T. Lam and P. Pylyavskyy.

The second new basis is the kaon basis, a $K$-theoretic deformation of the fundamental particle basis. We give positive expansions of the glide and Lascoux atom bases into this kaon basis.

Throughout, we explore how the relationships among these $K$-analogues mirror the relationships among their cohomological counterparts. We make several “alternating sum” conjectures that are suggestive of Euler characteristic calculations.

This bookmark gauges the depths of the human: how poetry can help to personalise climate change
Authors: Illingworth Sam
Published: September 2019

Abstract. By conducting a qualitative content analysis of 72 poems written about climate change by poets from across the world, this study demonstrates how these poets have interpreted the, at times, esoteric principles of climate change. The results of this study indicate that these interpretations highlight the need to re-position humans in the epicentre of the debate so that a meaningful dialogue around the subject might be established, especially amongst non-specialists.
Improved tropospheric and stratospheric sulfur cycle in the aerosol–chemistry–climate model SOCOL-AERv2
Authors: Feinberg Aryeh , Sukhodolov Timofei , Luo Bei-Ping , Rozanov Eugene , Winkel Lenny H. E. , Peter Thomas , Stenke Andrea
Published: September 2019

Abstract. SOCOL-AERv1 was developed as an aerosol–chemistry–climate model
to study the stratospheric sulfur cycle and its influence on climate and the ozone layer. It includes a sectional aerosol model that tracks the sulfate particle size distribution in 40 size bins, between 0.39 nm and 3.2 µm. Sheng et al. (2015) showed that SOCOL-AERv1 successfully matched observable quantities related to stratospheric aerosol. In the meantime, SOCOL-AER has undergone significant improvements and more observational datasets have become available. In producing SOCOL-AERv2 we have implemented several updates to the model: adding interactive deposition schemes, improving the sulfate mass and particle number conservation, and expanding the tropospheric chemistry scheme. We compare the two versions of the model with background stratospheric sulfate aerosol observations, stratospheric aerosol evolution after Pinatubo, and ground-based sulfur deposition networks. SOCOL-AERv2 shows similar levels of agreement as SOCOL-AERv1 with satellite-measured extinctions and in situ optical particle counter (OPC) balloon flights. The volcanically quiescent total stratospheric aerosol burden simulated in SOCOL-AERv2 has increased from 109 Gg of sulfur (S) to 160 Gg S, matching the newly available satellite estimate of 165 Gg S. However, SOCOL-AERv2 simulates too high cross-tropopause transport of tropospheric SO2 and/or sulfate aerosol, leading to an overestimation of lower stratospheric aerosol. Due to the current lack of upper tropospheric SO2 measurements and the neglect of organic aerosol in the model, the lower stratospheric bias of SOCOL-AERv2 was not further improved. Model performance under volcanically perturbed conditions has also undergone some changes, resulting in a slightly shorter volcanic aerosol lifetime after the Pinatubo eruption. With the improved deposition schemes of SOCOL-AERv2, simulated sulfur wet deposition fluxes are within a factor of 2 of measured deposition fluxes at 78 % of the measurement stations globally, an agreement which is on par with previous model intercomparison studies. Because of these improvements, SOCOL-AERv2 will be better suited to studying changes in atmospheric sulfur deposition due to variations in climate and emissions.

Abstract. Mapping the suitability of groundwater-dependent vegetation in semi-arid
Mediterranean areas is fundamental for the sustainable management of
groundwater resources and groundwater-dependent ecosystems (GDEs) under the
risks of climate change scenarios. For the present study the distribution of deep-rooted woody species in southern Portugal was modeled using climatic, hydrological and topographic environmental variables. To do so, Quercus suber, Quercus ilex and Pinus pinea were
used as proxy species to represent the groundwater-dependent vegetation (GDV). Model fitting was performed between the proxy species Kernel density and the selected environmental predictors using (1) a simple linear model and (2) a geographically weighted regression (GWR) to account for autocorrelation of the spatial data and residuals. When comparing the
results of both models, the GWR modeling results showed improved goodness
of fit as opposed to the simple linear model. Climatic indices were the main drivers of GDV density, followed by a much lower influence by
groundwater depth, drainage density and slope. Groundwater depth did not
appear to be as pertinent in the model as initially expected, accounting
only for about 7 % of the total variation compared to 88 % for climate
drivers. The relative proportion of model predictor coefficients was used as
weighting factors for multicriteria analysis to create a suitability map for the GDV in southern Portugal showing where the vegetation most likely relies on groundwater to cope with aridity. A validation of the resulting map was performed using independent data of the normalized difference water index (NDWI), a satellite-derived vegetation index. June, July and August of 2005 NDWI anomalies, for the years 1999–2009, were calculated to assess the response of active woody species in the region after an extreme drought. The results from the NDWI anomalies provided an overall good agreement with the suitability to host GDV. The model was considered to be reliable for predicting the distribution of the studied vegetation. The methodology developed to map GDVs will allow for the prediction of the evolution
of the distribution of GDV according to climate change and aid stakeholder
decision-making concerning priority areas of water resource management.
The Political-Military Foundations of China’s Global Ascendency
Authors: Major Aaron , Luo Zhifan
Published: September 2019

In recent years China has positioned itself as a global economic leader, working through its “Belt and Road” initiative (BRI) and Asian Infrastructure Investment Bank (AIIB), to not only expand its global economic reach, but to organize and lead global economic relations. China’s rise is largely understood in economic terms, but the history of global power dynamics suggests that such leadership is built on both economic and political-military foundations. This paper explores the structural relationship between China’s economic and political-military relationships with other states over the period 1993 to 2015. Drawing on a wide variety of data sources, we present a multi-dimensional analysis that measures the changing size of China’s economic and political-military networks, their shifting regional distribution, and the degree of coupling, or decoupling of economic ties from political-military ties. In describing these patterns, we conduct a similar analysis for the United States. This allows us to situate Chinese trends in the context of the structures of U.S. global power. Our analysis points to ways in which China’s global rise has been shaped through navigating U.S. global power. Our analysis also shows that China’s growing leadership in the global economy builds upon a set of existing political-military relationships that, while their scope and form are quite different from those that the United States built to support its hegemonic ascendency, are nevertheless critical for understanding the mechanisms by which Chinese power and influence has grown in the global political economy.

Climate Justice and Sustained Transnational Mobilization
Authors: Almeida Paul
Published: September 2019

Samir Amin’s final essay called for the creation of a new international organization of progressive social forces. This essay provides evidence from twenty-first century transnational movements on the likelihood of the emergence of such an international organization and the issues and sectors most likely to facilitate coalitional unity.  More specifically, the ecological crises identified by Amin in the form of global warming and climate change create an unprecedented global environmental threat capable of unifying diverse social strata across the planet.  The climate justice movement has already established a global infrastructure and template to coordinate a new international organization to confront neoliberal forms of globalization.  Pre-existing movement organizing around environmental racism, climate justice in the global South, and recent intersectional mobilizations serve as promising models essential to building an enduring international organization representing subaltern groups.
On Samir Amin’s Call for a Fifth International
Authors: Moghadam Valentine M.
Published: September 2019

In his prodigious output, from works on capitalist development to analyses of Islamist movements to involvement in the World Social Forum, Samir Amin’s was a consistent voice for struggle against capitalism’s domination of the world and its peoples.  In this brief essay I address his call for a shift from movement to organization, indeed, toward a kind of Fifth International (Amin 2018a) and explain why I endorse it.
Capital has an Internationale and it is Going Fascist: Time for an International of the Global Popular Classes
Authors: Robinson William I.
Published: September 2019

Robinson concurs with Amin’s centering of the problem of extreme concentration of capital and the centralization of power worldwide. However, he critiques Amin’s “tenacious nation-state/interstate framework,” arguing for an approach that transcends state-centrism to identify class and social dynamics that have enabled both the rise of the fascist right and create openings for emancipatory left formations.

Fugitive Literati: Black Girls’ Writing as a Tool of Kinship and Power at the Howard School
Authors: Owens Tammy C.
Published: September 2019

Teaching black children how to survive on their own was one of the primary goals of the Howard Orphanage and Industrial School (1868–1918) in New York. One skill, penmanship, proved to be particularly important for orphaned girls. “Fugitive Literati” examines an incident involving one of the institution’s former residents, a sixteen-year-old black girl domestic, who used her writing to resist being forced to marry a man who may have sexually assaulted her. Using black feminist thought to read the loud silences in the Howard Orphanage and Industrial School’s letters, I argue that the girl’s case shows how orphaned black girls used the “written word” to navigate power relations in the workplace and actively construct their desired kinship networks for survival. Further, I contend that the silences around the girl’s case in the archive tell of a strategy of dissemblance or the unique family-like veil of privacy within the institution.
Metacognitive Knowledge and Its Effect on Second Language Writing: Students' Perceptions of Writing Task
Authors: Saffari Narges
Published: September 2019

Metacognitive knowledge is a comparatively constant information show how human beings learn and process information in general and individual. It is also considered as a significant element in learners’ achievement inside and outside the classroom. The purpose of this paper is to understand the knowledge and beliefs L2 learners bring to writing tasks, and how the metacognitive knowledge they possess influences their approach to L2 writing. 50 undergraduate students were asked to fill the questionnaire and express their opinion on this matter. Findings of response data from questionnaires indicate that ESL writing is positively related to attention on the macro-level structure and negatively related to micro-level concerns.

Published: September 2019

The objective of this study is the production and the characterization of rice husk biosorbent. In fact, the biosorbent has been obtained by phosphoric acid treatment; its physicochemicals characteristics such as point of zero charge, specific surface, iodine number and chemicals functions have been determined. The analysis indicaded that, the point of zero charge is 8.7; for the pH value less than 8.7, the biosorbent surface is posotively charged and for pH value higher than 8.7, the biosorbent surface is negatively charged. The biosorbent iodine number is 1560.87±1 mg/g, it means that, the biosorbent is constituted in majority of microspores. Furthermore, the specific surface of biosorbent is 104.45±1m2/g, it is five times as big than untreated rice husk obtained by Dada and al., (2012). Acid treatment improve the porosity of biosorbent. Infrarouge spectrum present ether and aromatic functions.
An inverse problem for the second-order integro-differential pencil
Authors: Bondarenko Natalia  P.
Published: September 2019

We consider the second-order (Sturm-Liouville) integro-differential pencil with polynomial dependence on the spectral parameter in a boundary condition. The inverse problem is solved, which consists in reconstruction of the convolution kernel and one of the polynomials in the boundary condition by using the eigenvalues and the two other polynomials. We prove uniqueness of solution, develop a constructive algorithm for solving the inverse problem, and obtain necessary and sufficient conditions for its solvability.
A jednak osobowość! Dobry nauczyciel języka obcego w świetle wypowiedzi polskich uczniów i studentów
Authors: Mihułka Krystyna , Chojnacka-Gärtner Joanna
Published: September 2019

The aim of this article is to present a portrait of the so-called good foreign language teacher, which has been created on the basis of the comments made by about 850 Polish students of modern languages, and students representing various types of schools (from primary schools, through middle schools, to secondary schools). In this picture, teacher personality traits, the majority of which are regarded as values not only in professional life (e.g. in the teaching profession), but also in personal life, have ranked the highest. Personality traits have overshadowed the other two groups of qualities which foreign language teachers are also equipped with, i.e. didactic and glottodidactic ones. The presentation of the research results has been preceded by a theoretical part where teacher personality and its role in (language) education have been briefly discussed.
