The Development and Fragmentation of Kuwait's al-Jama'a al-Salafiyya: Purity over Pragmatism
Authors: Pall Zoltan
Published: May 2020

This article argues that the pragmatism displayed by Salafi politicians after the 2011 Arab uprisings might not apply to the larger networks of the movement. Such pragmatism contributed to organizational dysfunction in Kuwait's largest Salafi group, al-Jama'a al-Salafiyya. The ideological
foundations of the group stood at odds with its extensive institutional structures, impeding it from functioning effectively. To explain this, the article draws on a comparison with the Muslim Brotherhood in Kuwait, whose ideology and disciplinary practices facilitated the establishment of
tight-knit, highly efficient organizations.
How and Why Has the Muslim Brotherhood in Jordan Changed since 2011?
Authors: Rumman Mohammad Abu , Bondokji Neven
Published: May 2020

In the wake of the Arab Spring, many younger members of the Muslim Brotherhood in Jordan left the movement, especially after 2015, establishing new political parties due to ideological shifts over the nature of the state and questions of civil liberties. Four factors influenced this
transformation: identity crisis, the movement's organizational rigidity, members' personal experiences during and after the uprisings, and a growing desire to separate political campaigning from religious outreach.
Tunisia's Foiled Coup of 1987: The November 8th Group
Authors: Grewal Sharan
Published: May 2020

In 1987 Tunisian prime minister Zine al-'Abidine Ben 'Ali seized power from the ailing president, Habib Bourguiba. Less well-known is that Ben 'Ali's coup had preempted another coup plot planned for the following day. This article recounts the story of this latter plot, led by the November 8th Group, a coalition of about 200 individuals in the military, security forces, and the Islamic Tendency Movement (MTI). Drawing on memoirs and interviews, the article explores the plotters' motivations, post-takeover plans, and ultimate failure. It highlights how Bourguiba's coup-proofing strategies shaped the plot and its outcome, concluding with a discussion on the foiled coup's lasting impact on Tunisian civil-military relations.

Published: May 2020

Background: Among the various complications of diabetes, lower-extremity amputation due to diabetic foot is a common problem. In Pakistan, 6-7% of patients with diabetes suffer from diabetic foot ulceration.
Objectives: Our primary objective was to explore the frequency of diabetic foot amputations, and the secondary objective was to calculate the economic burden of these preventable surgeries on the health budget of the provincial government.
Materials & Methods: It was a retrospective cross-sectional observational study conducted after obtaining approval from the Ethical Review Committee of Allied hospital, Faisalabad Medical University. The data of diabetic foot patients who underwent amputations between July 2017 and December 2017 were retrieved from three Surgical Units (I, II & III), using a purposive sampling technique. All amputations carried out for reasons other than diabetic foot were excluded. The direct medical cost of one diabetic foot amputation was calculated via a local survey of the various private hospitals of Faisalabad. The indirect costs in terms of loss of productivity and disability costs, transport costs, rehabilitation costs were not included in this study. The data were evaluated by using SPSS Version 23.
Results: A total of 85 patients were included in our study. The male to female ratio was 2.7 to 1. The mean direct treatment cost for minor amputation was PKR 46926.00 ± 11730.90 ($382.35 ± 95.58), and the mean direct treatment cost for major amputation was PKR 53720.00 ± 12401.24 ($437.71 ± 101.40). Out of 85 amputations, 63 (74%) were major amputations, and the remaining 22 (26%) were minor amputations. The total cost for 63 major amputations was PKR 3,384,360 ($27568.91) and for 22 minor amputation was PKR 1,032,372 ($8409.67). The net cost came out to be PKR 4,416,732 ($35978.59) for all the 85 cases being reported in a tertiary care hospital of Faisalabad for six months.
Conclusion: Diabetic foot, a preventable complication of long-term diabetes mellitus, has an economic burden on the hospital budget, which, if adequately addressed via primary prevention programme, can yield not just economical but medical benefits as well.

Effects and Quantıty Ranges of Some Auxıns on Embryogenıc Callus Inductıon From Upland Rıce Cultıvars: An Overview
Authors: MOHAMMED Sulaiman
Published: May 2020

Embryogenic callus induction from indica rice sub-species, upland cultivars has remain a challenging task, but PGRs have been found to play a vital role in enhancing the production. Hence, solving this tricky problem and achieving optimum embryogenic callus induction from this special type of rice is a welcome development as food security concern, while proper examination of the appropriate PGRs is the only solution. Here we reviewed on two auxins-PGRs that promote the embryogenic callus induction from upland rice, viz., 2,4-D and NAA with their recommendable quantity ranges. 2,4-D and NAA were the most commonly employed and discovered best growth hormones in PTC irrespective of explant in all cereal plants. They are found the most suitable hormones and positively upgrade the production of reproducible callus. Classical analyses implies that medium supplemented with such PGRs provides necessities for quality callus from upland rice. Evidences indicated that callus induction or somatic embryogenesis from matured seeds of upland rice is persuade by 2,4-D between 1.0 – 2.5 mg/L concentrations. Whereas for NAA, to obtain its desired effects on upland rice callus induction it must be fortified in concentrations ranging from 0.5 mg/L to 10 mg/L. But convincingly, 0.5 – 5.0 mg/L NAA with other PGR like 2,4-D would be more proper. Hence, extensive studies of these hormones and others will provide insights on their potentialities to embryogenic callus induction and probably identify more of their roles in PTC analysis.

Abstract:
Aim: To investigate the effect of gonadotrophin releasing hormone agonist (GnRH-a) addition to luteal phase support (LPS) in intracytoplasmic sperm injection-embryo transfer (ICSI-ET) cycles of GnRH-a long protocol and GnRH antagonist (GnRH-anta) protocol, on pregnancy rates and outcomes.
Materials and Method: One hundred and eight infertile couples treated with ICSI-ET were included in this prospective randomized study. Patients were randomly divided into two groups to undergo two different ovarian stimulation protocols. GnRH-a iong protocol was applied to group I and GnRH-anta protocol was applied to group II. Women to be treated by each of the two protocols were also randomly assigned to one of the two subgroups. Subgroups Ib and IIb received leuprolide acetate (0.5 mg s.c.) injections on the 5th and 10th days after ET in addition to routine LPS [90 mg/day of vaginal progesterone plus 4 mg of 17β Estradiol]. Only routine LPS was given to other two subgroups (groups la and IIa).
Results: The total number of retrieved oocytes and MII oocytes were significantly higher in group Ia than in group Ib. There were no differences between subgroups in groups I and II regarding clinical pregnancy, ovarian hyperstimulation syndrome (OHSS), multiple pregnancy, abortion, ongoing pregnancy and live birth rates.
Conclusion: Addition of GnRH-a to routine LPS in ICSI-ET cycles of GnRH-a long protocol and GnRH-anta protocol seems to have no effect on ongoing pregnancy, abortion, multiple pregnancy, OHSS, clinical pregnancy and live birth rates.
Early Results of ERAS (Enhanced Recovery After Surgery) Protocol in Orthopaedic Surgery
Authors: Shah Jaydeep , Singhal Keshav
Published: May 2020

Background: The concept of a fast track (Enhanced Recovery After Surgery, ERAS) was introduced to colorectal surgery in Denmark by Kehlet in 1999 which improved the quality of the care and reduced the length of hospital stay following major colorectal surgery. The same principles of ERAS have been applied to the orthopaedic surgery particularly the hip and knee replacement surgery and fracture neck of femur surgery. It is a relatively new approach in orthopaedics to the preoperative, intraoperative and postoperative care of the patients undergoing surgery.

 

Methods: We have compared the length of inpatient stay, day of mobilisation, postoperative blood transfusion and adverse outcome for the patients undergoing hip or knee replacement by a single surgeon (KS) between ERAS and NON ERAS patients.

 

Results: A total of 138 patients underwent hip or knee replacement, hip resurfacing arthroplasty or oxford unicompartmental arthroplasty between July 2011 and June 2012 with ERAS protocol. In the Non-ERAS group, 140 patients underwent hip or knee arthroplasty, resurfacing or oxford uni-compartmental knee replacement in the previous year (July 2010 to June 2011) by the same surgeon.

Average hospital inpatient stays for the ERAS patients was 4.12 days with 73.10% of the patients having an inpatient hospital stay of less than or equal to 5 days. The average hospital inpatient stays for the NON-ERAS patients was 8.34 days with only 24.08% of the patients being discharged in less than or equal to 5 days.

 

Conclusions: Our study shows that the implementation of the ERAS protocol in hip and knee replacement surgery is associated with improved patient experience, faster recovery and shorter hospital inpatient stay with no increase in complication.
SHARPER EXISTENCE AND UNIQUENESS RESULTS FOR SOLUTIONS TO THIRD-ORDER BOUNDARY VALUE PROBLEMS
Authors: Almuthaybiri Saleh S. , Tisdell Christopher C.
Published: May 2020

The purpose of this note is to sharpen Smirnov’s recent work on existence and uniqueness of
solutions to third-order ordinary differential equations that are subjected to two- and three-point boundary conditions.
The advancement is achieved in the following ways. Firstly, we provide sharp and sharpened estimates for integrals
regarding various Green’s functions. Secondly, we apply these sharper estimates to problems in conjunction with Banach’s
fixed point theorem. Thirdly, we apply Rus’s contraction mapping theorem in a metric space, where two metrics are employed.
Our new results improve those of Smirnov by showing that a larger class of boundary value problems admit a unique solution.
Survival of Primordial Planetary Atmospheres: Photodissociation-driven Mass Loss
Authors: Howe Alex R. , Adams Fred C. , Meyer Michael R.
Published: May 2020

The most widely studied mechanism of mass loss from extrasolar planets is photoevaporation via X-ray and ultraviolet ionization, primarily in the context of highly irradiated planets. However, the extreme ultraviolet dissociation of hydrogen molecules can also theoretically drive atmospheric evaporation on low-mass planets. For temperate planets such as the early Earth, impact erosion is expected to dominate in the traditional planetesimal accretion model, but it would be greatly reduced in pebble accretion scenarios, allowing other mass-loss processes to be major contributors. We apply the same prescription for photoionization to this photodissociation mechanism and compare it to an analysis of other possible sources of mass loss in pebble accretion scenarios. We find that there is no clear path to evaporating the primordial atmosphere accreted by an early Earth analog in a pebble accretion scenario. Impact erosion could remove ∼2300 bars of hydrogen if 1% of the planet’s mass is accreted as planetesimals, while the combined photoevaporation processes could evaporate ∼750 bars of hydrogen. Photodissociation is likely a subdominant but significant component of mass loss. Similar results apply to super-Earths and mini-Neptunes. This mechanism could also preferentially remove hydrogen from a planet’s primordial atmosphere, thereby leaving a larger abundance of primordial water compared to standard dry formation models. We discuss the implications of these results for models of rocky planet formation, including Earth’s formation, and the possible application of this analysis to mass loss from observed exoplanets.
On the Ratios of Si IV Lines (λ1394/λ1403) in an Emerging Flux Region
Authors: Tripathi Durgesh , Nived V N , Isobe Hiroaki , Doyle G. Gerard
Published: May 2020

The resonance lines of Si iv formed at λ1394 and 1403 Å are the most critical for the diagnostics of the solar transition region in the observations of the Interface Region Imaging Spectrograph (IRIS). Studying the intensity ratios of these lines (1394 Å/1403 Å), which under optically thin conditions is predicted to be two, helps us to diagnose the optical thickness of the plasma being observed. Here we study the evolution of the distribution of intensity ratios in 31 IRIS rasters recorded for four days during the emergence of an active region. We found that during the early phase of the development, the majority of the pixels show intensity ratios smaller than two. However, as the active region evolves, more and more pixels show the ratios closer to two. Besides, there are a substantial number of pixels with ratio values larger than 2. At the evolved stage of the active region, the pixels with ratios smaller than two were located on the periphery, whereas those with values larger than 2 were in the core. However, for quiet Sun regions, the obtained intensity ratios were close to two irrespective of the location on the disk. Our findings suggest that the Si iv lines observed in active regions are affected by the opacity during the early phase of the flux emergence. The results obtained here could have important implications for the modeling of the solar atmosphere, including the initial stage of the emergence of an active region as well as the quiet Sun.

Green valley galaxies represent the population that is likely to transition from star-forming to quiescent phases. To investigate the role of the environment in quenching star formation, we use the wide-field data from the Hyper Suprime-Cam Strategic Subaru Proposal survey to quantify the frequency of green valley galaxies in different environments and their redshift evolution. We find that the green valley fraction, in general, is less than 20% in any redshift and environment. The green valley fraction, when normalized to the total population, is higher in the field than that in groups or clusters and decreases with decreasing redshift and increasing mass. The lower fraction of transitional galaxies in denser environments could be a consequence of the lack of star-forming galaxies, which could be the progenitors of green valley galaxies. To assess the effect of the environment on star formation quenching, we define the effective green valley fraction as the ratio of the number of green valley galaxies to that of nonquiescent galaxies only. The effective green valley fraction for field galaxies is lower than that for group or cluster galaxies, which reveals a strong positive mass dependence and mild redshift evolution. Moreover, the specific star formation rate is reduced by 0.1–0.3 dex in groups or clusters. Our results thus imply that an ongoing slow quenching process has been acting in the dense environment since z ∼ 1.
A Fully Time-dependent Ab Initio Cosmic-Ray Modulation Model Applied to Historical Cosmic-Ray Modulation
Authors: Moloto K. D. , Engelbrecht N. Eugene
Published: May 2020

Cosmogenic nuclide records can in principle allow for the estimation of the behavior of the heliospheric magnetic field (HMF) in the distant past. This requires careful modeling of cosmic-ray transport in a manner that is as realistic as possible, taking into account as many of the factors affecting the transport of cosmic-rays (CRs) as possible. The present study presents a 3D time-dependent ab initio CR modulation code that utilizes as inputs simple theoretically and observationally motivated temporal profiles to model large-scale (such as the tilt angle) and small-scale (such as the magnetic variance) parameters relevant to CR transport. Galactic CR proton differential intensities computed using this model for the period 1977–2001 are in reasonable to good agreement with spacecraft observations, reproducing the major salient features of the observed CR intensity temporal profile. To investigate pre-space-age cosmic-ray modulation, and to test conclusions previously drawn regarding the relative importance of drift effects on said modulation, historic estimates of the past HMF presented by McCracken & Beer were used as inputs for the model. The resulting CR temporal intensity profile displays clear evidence of drift effects, with a sharp peak in intensities during the Dalton Minimum.

Published: May 2020

BACKGROUND: The issue of the influence of psychics on somatic diseases, including cancer, becomes more and more relevant. In cases with cancer, patients face a vital threat, which, in its turn, is manifested as a range of biopsychosocial consequences.
AIM: The aim of the study was to reveal the factors of the formation of fear of cancer progression or recurrence in breast cancer patients.
METHODS: The sampling included patients from clinical hospitals of Moscow and Saint Petersburg (Russia). The study involved 690 patients aged 30â€“79 years old. The study was performed with specially selected diagnostic tools that allowed the authors to evaluate the intensity and reveal peculiarities of the development of fear of cancer progression. Statistical analysis was performed by the calculation of the mean arithmetic of the general sampling, the rate, and the ratio distribution by the intensity of fear of cancer progression, and Spearman correlation.
RESULTS: Statistically significant associations were revealed between the parameters of intensity and peculiarities of fear of cancer progression and such characteristics of personality as viability, integrated personality, and experiences in a close relationship.
CONCLUSION: The obtained results were used to develop methodical recommendations on the improvement of a psychoemotional condition of women diagnosed with breast cancer.

Authors: Al-Radeef Mohanad Y. , Abood Sattar J. , Abdulsahib Waleed K. , Hamad Salah O.
Published: May 2020

BACKGROUND: Post-operative nausea and vomiting (PONV) and pain are a common complications of adult patients undergoing anesthesia, but the incidence of these complications in patients go through laparoscopic cholecystectomy or open appendectomy is unknown.
AIM: We conduct this study for comparing the effect of dexamethasone administration with normal saline and with metoclopramide for reducing these undesirable effects.
DESIGN: This was a three-armed, parallel-group, double-blind, and randomized controlled clinical trial.
METHODS: Seventy-two patients of both genders underwent elective surgeries (laparoscopic cholecystectomy or open appendectomy), randomly assigned to three groups: A dexamethasone-treated (8 mg) group (Group 1) (n = 24), normal saline-treated (100 ml) group (Group 2) (n = 24), and metoclopramide-treated (10 mg) group (Group 3) (n = 24). All nausea, vomiting, and pain episodes were recorded during 24 h after anesthesia in three time periods: 0–4, 4–12, and 12–24 h post-anesthesia.
Results: Nausea and vomiting grading scale shows no significant difference when compare dexamethasone (Group 1) with normal saline (Group 2), significant difference when compare dexamethasone (Group 1) with metoclopramide (Group 3), and also significant difference when compare normal saline (Group 2) with metoclopramide (Group 3). Group 1 showed a lower pain score (p < 0.01 and p < 0.0001) compared with pain score recorded by patients of Groups 2 and 3, respectively. Besides that, Group 2 also showed a lower pain score (p < 0.0001) compared with pain score recorded by Group 3 patients.
CONCLUSION: Dexamethasone has unimportant effect when compare with normal saline, more effectiveness than metoclopramide in reducing PONV. However, dexamethasone more effective in reducing pain when comparing with normal saline and metoclopramide for patients they underwent laparoscopic cholecystectomy or open appendectomy surgery under general anesthesia.
Microhabitats of planted sea wall strips used by pollinators and Orthoptera
Authors: Gardiner Tim , Fargeaud Kimberley
Published: May 2020

As part of an Urban Buzz scheme, strips of teasel (Dipsacus fullonum) and greater knapweed (Centaurea scabiosa) have been established along a sea wall flood defense in the UK to provide a corridor of flower-rich habitat for pollinators such as bees and butterflies. The cutting of tall grassland and planting of dicotyledons also created a suitable short sward environment (c. 30 cm height) for Orthoptera nymphs in the establishment year (2018). However, by 2019, the grassland in the pollinator strips was taller (c. 75 cm) and suboptimal for grasshoppers; in contrast to Roesel’s bush-cricket (Roeseliana roeselii), which inhabited the taller vegetation in greater abundance. The progression to established grassland with flowering D. fullonum saw the pollinator strips attract significantly higher numbers of bees and butterflies than the floristically poor control strips. This small-scale study illustrates that pollinator strips can have multi-functional benefits for ecosystems beyond pollination, with Orthoptera of tall grassland (R. roeselii) likely to persist alongside planted wildflowers.
Consequences of advanced maternal age on reproductive investment by male offspring
Authors: Wilson Jacob D. , Anner Sophia C. , Murphy Shannon M. , Tinghitella Robin M.
Published: May 2020

Maternal age can have contrasting effects on a variety of offspring fitness traits. While the effects of maternal age on offspring traits that are not sex-specific, such as body size and growth rate, as well as on traits specific to females, have been well researched, traits that are specific to male offspring have been understudied. Across taxa, male reproductive investment is a particularly salient component of fitness, especially when females mate with several males. We tested whether maternal age affects the reproductive traits of their male offspring by comparing the investment made by male field crickets, Teleogryllus oceanicus, from ‘young’ and ‘old’ maternal age treatments. Female T. oceanicus mate with several males, and sperm competition is a fair lottery, so male reproductive investment is important for fitness in this system. After two generations of mating young and old females, we measured the testes mass, spermatophore mold mass, and sperm viability of their male offspring. Despite differences in maternal and grand-maternal age and the demonstrated effects of advanced maternal age on egg number and offspring immunocompetency in this system, the male offspring of young and old females did not differ in reproductive tissues and sperm viability. This study is one of the first to examine the effect of maternal age on fitness-related traits specific to male offspring, and we encourage future research that tests the effects of maternal age on male offspring in other species.
Influence of cold temperature and exposure time on egg overwintering survival in the white-whiskered grasshopper (Orthoptera: Acrididae)
Authors: Branson David H.
Published: May 2020

The effect of cold temperatures and exposure time on egg survival and hatching success were examined in the white-whiskered grasshopper, Ageneotettix deorum. Temperature treatments ranged from 4°C to -35°C, with treatment times ranging from 48 to 240 hours. Both decreasing temperatures and exposure time negatively affected egg survival, with a temperature below -25°C being lethal. Similar lethal temperatures are known for several North American grasshopper species. The relatively shallow location of A. deorum egg pods would result in increased vulnerability of eggs to cold temperatures in the absence of snow.
Clonal growth strategies of Reynoutria japonica in response to light, shade, and mowing, and perspectives for management
Authors: Martin François-Marie , Dommanget Fanny , Lavallée François , Evette André
Published: May 2020

Many of the most invasive plant species in the world can propagate clonally, suggesting clonality offers advantages that facilitate invasion. Gaining insights into the clonal growth dynamics of invasive plants should thus improve understanding of the mechanisms of their dominance, resilience and expansion. Belonging to the shortlist of the most problematic terrestrial invaders, Reynoutria japonica var. japonica Houtt. (Japanese knotweed) has colonized all five continents, likely facilitated by its impressive ability to propagate vegetatively. However, its clonal growth patterns are surprisingly understudied; we still do not know how individuals respond to key environmental conditions, including light availability and disturbance. To contribute to filling this knowledge gap, we designed a mesocosm experiment to observe the morphological variation inR. japonicagrowth in homogeneous or heterogeneous conditions of light stress (shade) and disturbance (mowing). Rhizome fragments were planted in the middle of large pots between two habitat patches that consisted of either one or a combination of the following three environmental conditions: full light without mowing, full light with frequent mowing, or shade without mowing. At the end of the experiment, biomass and traits related to clonal growth (spacer and rhizome lengths, number of rhizome branches, and number of ramets) were measured. After 14 months, all individuals had survived, even those frequently mowed or growing under heavy shade. We showed thatR. japonicaadopts a ‘phalanx’ growth form when growing in full light and a ‘guerrilla’ form when entirely shaded. The former is characteristic of a space-occupancy strategy while the latter is more associated with a foraging strategy. In heterogeneous conditions, we also showed that clones seemed to invest preferentially more in favorable habitat patches rather than in unfavorable ones (mowed or shaded), possibly exhibiting an escape strategy. These observations could improve the management of this species, specifically by illustrating how aggressive early control measures must be, by highlighting the importance of repeated mowing of entire stands, as this plant appears to compensate readily to partial mowing, and by informing on its potential responses towards the restoration of a cover of competitive native plants.
Do dense layers of invasive plants elevate the foraging intensity of small mammals in temperate deciduous forests? A case study from Pennsylvania, USA
Authors: Utz Ryan M. , Slater Alysha , Rosche Hannah R. , Carson Walter P.
Published: May 2020

Monospecific stands of invasive plants can dramatically restructure habitat for fauna, thereby elevating population densities or promoting foraging of consumer species who benefit in the altered habitat. For example, dense stands of invasive plants may protect small mammals from predators, which in turn could increase foraging pressure on seeds that small mammals feed upon. We used a before-after, control-impact experimental design to test whether small mammal capture rates were higher and giving-up densities (GUDs) lower beneath dense stands of Berberis thunbergii, an invasive shrub with a rapidly expanding range throughout eastern North America. Our experimental design included three plot categories: 1) plots heavily invaded by B. thunbergii, 2) control plots lacking invasive shrub cover, and 3) invaded plots where we eradicated B. thunbergii midway through the study. Although our overall small mammal capture rate was low, small mammal captures were 65% higher in B. thunbergii invaded habitat relative to control plots and eradication lowered capture rates by 77%. GUDs were also 26% higher within B. thunbergii relative to control plots and eradication decreased GUDs by 65%. Our findings suggest that small mammals perceive dense stands of B. thunbergii as relatively safe foraging habitat. Prior surveys within our study locations revealed dramatically depressed tree seedling densities under B. thunbergii, thus invasive plants may promote intensive foraging by small mammals and reduce recruitment for species with foraged seeds or seedlings.

¿Una feria de cambios a la valenciana? Debate financiero y energía emprendedora en el siglo XVII
Authors: San Ruperto Albert Josep
Published: May 2020

En 1619 Felipe IV dio a la estampa una Real Pragmática con la finalidad de regular los cambios realizados entre Valencia y Medina del Campo, llevados a cabo por las familias de negocios en Valencia para percibir intereses por sus préstamos, sin ser acusados de usura. En 1622, la Repú­blica de Génova inauguraba las ferias cambiarias de Novi Ligure, conso­lidando su posición internacional en el mercado del crédito. Estos dos hechos, aparentemente independientes entre sí, conforman un episodio importante para el conocimiento financiero internacional y las transfor­maciones del mercado del crédito mediterráneo durante el siglo XVII. El estudio de las innovaciones financieras en el Mediterráneo puede ofrecer luz sobre la adaptación a un mundo cada vez más global. Es por ello que en este artículo se analizará el sistema de préstamos y cambios en la Edad Moderna, destacando la centralidad de las ferias de Medina del Campo en la Península Ibérica. Posteriormente se estudiará de forma compara­tiva cómo los valencianos usaron las ferias de Medina al igual que los genoveses las de Novi Ligure e, incluso, se prestará atención a la pro­puesta de creación de una institución de cambios propia. Por último, se mostrará cómo Valencia albergó una energía emprendedora durante el seiscientos.

Published: May 2020

Spent catalyst is listed as one of the hazardous wastes. Based on the toxicity characteristic shows that spent catalyst contains some heavy metals at concentration above the regulations limits. This situattion becomes an important issue in nowadays. In this research, fungus Aspergillus niger was investigated to produce weak organic acid (citric acid). Batch experiments were performed to compare the leaching efficiency from spent catalyst of pulp density (2% and 4%) and particle size (212 µm, 150 µm and 75 µm). Result showed that after direct bioleaching process, maximum recovery of valuable metal 24.94%, 7.42%, 1.09%, 3.51%, 4.87% and 1.66% were achieved for aluminum, calcium, iron, copper, silver and platinum respectively at 2% pulp density. Overall data shows that metal recovery at pulp density 2% are higher than 4% pulp density. The maximum recovery based on particle size shows that the smaller particle (75 µm) the higher metal recovery (Al, Ag and Pt) and for some metals was different such as Fe, Cu and Ca.

Rubber compound supplies are very important in supporting the outsole production process, in order to obtain good results and increase production efficiency. However, the rubber outsole company at west java used excessive rubber material for producing outsole. Furthermore, the situation is identified as the company has an inefficient distribution system of the rubber compound. Therefore, there is an abundant solid waste of rubber compound in the outsole pressing process. This research aims to reduce the waste of rubber compounds by regulating the rubber compound distribution using Material Requirement Planning (MRP) with a fixed order quantity lot-sizing technique. The using of MRP will lead to the consumption of the rubber compound can be controlled properly. Moreover, by reducing the utilization of rubber material, the company can minimize solid waste. The result shows that the company can reduce 38.75 kg/day rubber material for production line 1, while 3.69 kg/day for production line 2. Therefore, in one year the company can cut the consumption of the rubber material about 23.57 tons. By reducing the utilization of rubber material, the result indicates that the method can reduce the loss of production worth Rp. 5,240,000/day. Furthermore, this paper also recommends incorporating demand uncertainty of the outsole product in future research.

The implementation of the waste management technology in Integrated Waste Management Site, in Bahasa: Tempat Pengolahan Sampah Terpadu (TPST) Piyungan of the Special Region of Yogyakarta Indonesia has not been optimal and it has negative impact, especially on environment and surrounding community. TPST Piyungan has both positive impact of opening employment for waste pickers as well as negative impact of pollution in surrounding environment. Increasing of solid waste input is not balanced with the processing rate. Concerning with the aforementioned background the study aimed at studying the people perception of waste management in the TPST Piyungan and formulating a new paradigm for solid waste management in TPST Piyungan by proposing a waste-to-energy technology that able to solve the existing problems and become a business-centered activity instead of cost-centered, or in short term waste-entrepreneurship (wastepreneurship). The study was conducted in TPST Piyungan and surroundings villages as samples. The study used quantitative analysis method. People perception were collected using questionnaires distributed to 30 respondents in nearby villages. Proposed technology was selected using Green Quality Function Deployment (GQFD) and Less Objective Criteria (LOC). Economic evaluation parameters are Net Present Value (NPV), Internal Rate of Return (IRR) and Payback Period. The results of the study showed that 70% of the villagers accepted the presence of the advanced waste management in the TPST Piyungan. The results of GQFD and LOC showed that incinerator was the selected technology. The results of economic showed that incinerator was economically feasible with the NPV of IDR 86.09 billion, the IRR of 13.35%, and the net profit margin in the range of 6.89 – 18.79% in the operational period of 18 years, and the static payback period of 7 years. Therefore, the implementation of wastepreneurship in form of social, economic, technical and environment is highly potential.
Androgen downregulation of miR-760 promotes prostate cancer cell growth by regulating IL6

Published: May 2020

Prostate cancer (PCa) is one of the most common malignancies in Western countries. Studies have shown that androgen contributes to the progression of PCa, but how androgen promotes PCa remains largely unknown. Here, we demonstrated that androgen suppressed the expression of miR-760 depending on the interaction between androgen and androgen receptor (AR). miR-760 was downregulated in prostate cancer tissues compared with normal tissues. Functional experiments showed that miR-760 downregulation promoted the proliferation and growth of LNCaP and 22rv1 cells. In contrast, miR-760 ectopic expression inhibited the proliferation of LNCaP and 22rv1 cells. DNA synthesis was suppressed by miR-760. Mechanistically, miR-760 bound to the 3'UTR of interleukin 6 (IL6). A mutation in the binding site disrupted their interaction. In addition, silencing of IL6 suppressed the proliferation of LNCaP and 22rv1 cells. IL6 was upregulated in PCa tissues. Our study reveals that androgen downregulates miR-760 to promote the growth of PCa cells by regulating IL6.
Hecke operators in $KK$-theory and the $K$-homology of Bianchi groups

Let

\Gamma

be a torsion-free arithmetic group acting on its associated global symmetric space

X

. Assume that

X

is of non-compact type and let

\Gamma

act on the geodesic boundary

\partial X

of

X

. Via general constructions in

KK

-theory, we endow the

K

-groups of the arithmetic manifold

X / \Gamma

, of the reduced group

C^*

-algebra

C^*_r(\Gamma)

and of the boundary crossed product algebra

C(\partial X) \rtimes\Gamma

with Hecke operators. In the case when

\Gamma

is a group of real hyperbolic isometries, the

K

-theory and

K

-homology groups of these

C^{*}

-algebras are related by a Gysin six-term exact sequence and we prove that this Gysin sequence is Hecke equivariant. Finally, when

\Gamma

is a Bianchi group, we assign explicit unbounded Fredholm modules (i.e. spectral triples) to (co)homology classes, inducing Hecke-equivariant isomorphisms between the integral cohomology of

\Gamma

and each of these

K

-groups. Our methods apply to case

\Gamma \subset \mathbf {PSL}(\mathbf Z)

as well.

In particular we employ the unbounded Kasparov product to push the Dirac operator an embedded surface in the Borel–Serre compactification of

\mathbf H/\Gamma

to a spectral triple on the purely infinite geodesic boundary crossed product algebra

C(\partial \mathbf H) \rtimes\Gamma

Universal regularity of higher-dimensional disorder and density of states under non-local interactions. I. Infinite smoothness and localization
Authors: Chulaevsky Victor
Published: May 2020

It is shown that in a large class of disordered systems with singular alloy-type disorder and non-local media-particle interactions, the marginal measures of the induced random potential and the finite-volume integrated density of states (IDS) are infinitely differentiable in higher dimensions.

The proposed approach complements the classical Wegner estimate which says that the IDS in the short-range models is at least as regular as the marginal distribution of the disorder. In the models with non-local interaction the finite-volume IDS is much more regular than the underlying disorder. In turn, smoothness of the finite-volume IDS is responsible for a mechanism complementing the Lifshitz tails phenomenon.

The new eigenvalue concentration estimates give rise to relatively simple proofs of Anderson localization in several classes of discrete and continuous long-range models with arbitrarily singular disorder. The present paper addresses the model with power-law decay of the potential.

Water Temperature Increasing Caused Mastigias Papua Disappeared in Marine Lake Lenmakana Misool Raja Ampat Regency, West Papua
Authors: Purba Gandi YS
Published: May 2020

Mastigias papua is a jellyfish that is trademark of marine lakes. Ongeim’l Tketau Lake in Palau, Hang Du I Lake in Vietnam, Kakaban Lake in Kalimantan, and Lenmakana Lake in Raja Ampat Papua are exotic tourist destinations because of presence of these biota in the lake. Water temperature is very influential on the life of a jellyfish because of its mutual symbiosis with brown algae zooxanthellae. Mastigias has totally disappeared in several places due to water temperature increasing, including Lenmakana Lake in the West Monsoon 2017/2018 and 2018/2019. The absence of Mastigias in this lake will be explained by recorded logger data installed in the lake and at sea. Secondary data from NOAA and BMKG will be used to explain the condition of absence of jellyfish. Water lake temperature data showed an increase to 2.5oC when the Mastigias disappeared. Temperature increasing occur due to seasonal cycle patterns of lake water temperatures and weather cycles which change in time, the dry season occurs faster and the rainy season occurs slower. Conversely, in the West Monsoon 2019/2020, Mastigias still found in the lake. The rainy season which is 20 days faster than normal condition helps reduce the heat in West Monsoon.
Índios e militares no século XX: a invisibilidade do caos humano nas fronteiras.
Authors: Moreira Maria Geralda Almeida
Published: May 2020

A política indigenista adotada durante a Ditadura Militar visava, dentre outros objetivos, à ocupação da Amazônia por meio da construção de estradas, de hidrelétricas e do incentivo à migração para regiões consideradas, até então, como “vazios demográficos”. Essa política foi responsável pelo genocídio de etnias inteiras e pelo processo que buscava a transformação de índios em “não-índios”, a desindianização. Tais práticas mantiveram-se nos subterrâneos, não conseguiram extrapolar as fronteiras étnicas e permaneceram na memória dos sobreviventes desses massacres indígenas. O objetivo aqui consiste, por um lado, em analisar as ações empreendidas pelo Estado contra os indígenas, por considerá-los “subversivos”, e, por outro, em evidenciar a ação de resistência realizada pelos indígenas frente a essa política genocida. A pesquisa foi realizada, primordialmente, com base na documentação produzida pelo Comitê Estadual da Verdade do Amazonas e pela Comissão Nacional da Verdade.

Authors: Gomes Vera Lucia , Eleotério Valdênia Fernandes
Published: May 2020

Essa pesquisa teve como objetivo geral verificar como a educação do campo está organizada para atender as necessidades dos estudantes. A pesquisa foi realizada com três professores e três alunos de uma instituição universitária da zona rural de Aquidauana – MS. Observamos que a instituição organizou seu currículo para oferecer formação adequada de acordo com os cursos que oferece, entretanto falta apoio do poder público para melhor aproveitamento de todos os espaços e recursos do campus. Percebemos ainda, que os professores têm consciência da utilização de práticas pedagógicas diferenciadas mas ainda existe a necessidade do uso de recursos mais atualizados, como a tecnologia. O que incentivou os alunos a buscar os cursos oferecidos pela instituição foi a perspectiva de adquirir uma profissão, aumentar a produtividade e consequentemente sua remuneração.
