The Effect of Corruption on International Trade: A Case Study of Indonesian Trade to Nine Countries
Authors: Atsir Danang Ibnu , Sunaryati Sunaryati
Published: October 2018

Corruption is a form of abuse of ethical authority by public officials, which is divided into two parts: bribery and forced collection. The effect of corruption like bribes and illegal levies is widespread in the public sector. One interesting investigation is the effect of corruption on international trade. Corruption becomes a barrier in international trade, where corruption plays a role in the access of trade goods and services from within and abroad. Using the gravity model, the focus of this research was the effect of corruption on international trade by taking a case study of Indonesia’s bilateral trade with its nine largest export destination countries. Using panel data, analysis tools used in this research were common effect, fixed effect, random effect and poisson pseudo maximum likelihood (PPML). In this research, it was found that geographical distance variable in its fixed units caused the omitted variable so that the error term correlated with independent variables. In order to overcome the problem, poisson pseudo maximum likelihood method was used in performing regression gravity model with linear log form, so the omitted variable issue on the geographical distance can be eliminated. The results of this research concluded that corruption played a role in international trade through bureaucratic mechanisms of trade and investment licensing and the effect of corruption was more detrimental to exporters.Keywords:   Gravity Model, Corruption, International Trade, Poisson Pseudo Maximum Likelihood (PPML).
Improvement of Filler-Matrix Interactions in Polypropylene/Montmorillonite Nanocomposites by Usıng Irradiated Polypropylene
Authors: Zengin Fatma , Çağlayan Tahsin , Ide Semra , Güven Olgun
Published: October 2018

In the preparation of polymer-clay nanocomposites the chemical incompatibility between the clay surface and polyolefins can be overcome by using clays organically modified with short chain organic cations. The compatibility can be further enhanced by using functionalized polymer that wets the clay surface while being miscible with the non-polar polymer matrix. In this work we tried to modify the host polymer polypropylene (PP) by irradiating it with gamma-rays in air knowing that it undergoes oxidation and chain scission simultaneously. Thus lower molecular weight PP with highly polar surface due to oxidation can be expected to play double role of clay modifier and functional compatibilizer. This has been observed to be the case. Finely ground PP granules were irradiated in air in a 60Co γ-irradiator at the dose rate of 0.08 kGy/h (low dose rate to enhance oxidation) to 5, 10, and 20 kGy total doses. The extent of oxidation and change in molecular weight were determined by ATR-FTIR and Melt Flow Rate measurements respectively. PP/MMT nanocomposites were prepared by using 20% γ-PP, 1-5 % MMT and pristine PP to make up the total 100 in a torque rheometer. Maleated PP was also used in similar quantities to compare the effectiveness of γ-PP as a compatibilizing agent. Nanocomposites prepared with 10 kGy irradiated PP was found to show optimum mechanical properties among all formulations, with 26% increase in E-modulus and 10% increase in tensile strength as compared to pristine PP. Ternary PP nanocomposites were characterized by XRD, SAXS and PALS studies.

Keyhole neurosurgery implies reaching a target area inside the brain through an entry point specified by the neurosurgeon. In order to avoid complications, a risk assessment procedure must be done to establish the minimum risk trajectory from the entry point to the target area. The neurosurgeon establishes the risk values for the brain structure according to the type of intervention. The preset brain structure risk value is used to assess the risk value for each voxel of the brain. This paper proposes an improved risk assessment methodology based on the sum of N maximum risk values for each voxel. Then, risk assessment for a trajectory is done by adding the risk of all voxels that are part of the path. The safest trajectory is defined as the trajectory with the lower risk. Our proposed search trajectory methodology includes a Genetic Algorithm (GA) for finding the safest trajectories. The use of a GA drastically reduces the number of trajectories to analyze, speeding up the planning procedure. The achieved results were qualified by expert neurosurgeons as satisfactory. Our proposed method allows neurosurgeons to calibrate the surgical planning system by allowing them to establish the risk brain structure and the risk value for each structure.
Phase Evolution and Textural Changes during the Direct Conversion and Storage of CO2 to Produce Calcium Carbonate from Calcium Hydroxide
Authors: Liu Meishen , Gadikota Greeshma
Published: October 2018

The increasing use of energy resources recovered from the subsurface environments and the resulting carbon imbalance in the environment has motivated the need to develop thermodynamically downhill pathways to convert and store CO2 as water insoluble calcium or magnesium carbonates. While previous studies extensively explored aqueous routes to produce calcium and magnesium carbonates from CO2, there has been a limited scientific understanding of the phase evolution and textural changes during the direct gas-solid conversion routes to produce calcium carbonate from calcium hydroxide, which is one of the abundant constituents of alkaline industrial residues. With increasing interest in developing integrated pathways for capturing, converting and storing CO2 from dilute flue gases, understanding the compositions of the product phases as they evolve is essential for evaluating the efficacy of a given processing route. Therefore, in this study, we investigate the phase evolution and the corresponding textural changes as calcium hydroxide is converted to calcium carbonate under the continuous flow of CO2 at an ambient pressure of 1 atm and on heating continuously from 30 °C to 500 °C using in-operando wide angle X-ray scattering (WAXS), small angle X-ray scattering (SAXS), and ultra-small angle X-ray scattering (USAXS) measurements.

Published: October 2018

Over the past decades, research has escalated on the use of polylactic acid (PLA) as replacement for petroleum-based polymers. This is due to its valuable properties, such as renewability, biodegradability, biocompatibility and good thermomechanical properties. Despite possessing good mechanical properties comparable to conventional petroleum-based polymers, PLA suffers from some shortcomings such as low thermal resistance, heat distortion temperature and rate of crystallization, thus different fillers have been used to overcome these limitations. In the frame work of environmentally friendly processes and products, there has been growing interest on the use of cellulose nanomaterials viz. cellulose nanocrystals (CNC) and nanofibers (CNF) as natural fillers for PLA towards advanced applications other than short-term packaging and biomedical. Cellulosic nanomaterials are renewable in nature, biodegradable, eco-friendless and they possess high strength and stiffness. In the case of eco-friendly processes, various conventional processing techniques, such as melt extrusion, melt-spinning, and compression moulding, have been used to produce PLA composites. This review addresses the critical factors in the manufacturing of PLA-cellulosic nanomaterials by using conventional techniques and recent advances needed to promote and improve the dispersion of the cellulosic nanomaterials. Different aspects, including morphology, mechanical behavior and thermal properties, as well as comparisons of CNC- and CNF reinforced PLA, are also discussed

Published: October 2018

The use of fluoride (F-) for decreasing the prevalence and incidence of tooth decay was the greatest worldwide preventive public health measure of the 20th century. There have been controversial reports about the benefits of the use of F-, because in small amounts it helps prevent dental caries, but in high concentrations it can be potentially toxic and harmful to dental and systemic health. Since the mid-20th century, F- has been studied by toxicologists, looking at its deleterious effects in human populations. During the last decade, the interest on the undesirable effects has resurfaced because of the knowledge that it interacts with the cellular system, even in low doses, with a very small safety margin. Acute ingestion of toxic amounts of fluoride can cause corrosive gastric mucosa injury. Also respiratory effects such as bleeding, pulmonary edema, tracheostomy and shortness of breath, have been observed in individuals who inhale hydrogen fluoride. Some researchers had shown that F- is an oxidizing agent and a well-known reversible enzymatic inhibitor that interferes with the enzyme activity of at least 80 proteins, can altered the intracellular redox equilibrium, lipid peroxidation, as well as, alteration in the gene expression and apoptosis induction. The primary purpose of this review is to examine findings of the action of inorganic F-, and an overview of hard and soft tissue disturbances, known as fluorosis. The goal of this review is to enhance understanding of the mechanisms by which F- affects cells with an emphasis on human tissue-specific events.

Published: October 2018

The chemical synthesis of silver nanoparticles (Ag-NPs) by using an environmentally friendly methodology for their preparation is presented. Thus, considering that plants possess components that can act as reducing agents and stabilizers in the nanoparticles production, in this work, the synthesis of Ag-NPs by using a solution of grape waste extract as reducing and capping agent is studied. First, the total polyphenols content and reducing sugars in extracts produced at different conditions are characterized. After that, Ag-NPs are synthesized regarding the interaction of Ag ions (from silver nitrate) and the grape waste extract. The effect of temperature, contact time, extract/metal solution volume ratio and pH solution in the synthesis of metal nanoparticles are studied too. Different sets of nanoparticle samples are fully characterized by means of Electron Microscopy coupled with Energy Dispersive X-Ray for qualitative chemical identification. Ag-NPs with an average diameter of 27.7 ± 0.6 nm are selected to proof their suitability for sensing purposes. Thus, screen-printed electrodes modified with Ag-NPs are tested for the simultaneous voltammetric stripping determination of Pb(II) and Cd(II). Results indicate good reproducibility, sensitivity and limits of detection around 2.7 µg L−1 for both metal ions.

Authors: Tolcha Mesay Alemu , Altenbach Holm
Published: October 2018

In the world industry plant, solid and solid metals are always in contact even their motions not independent. Modeling of rolling die contact with slab primarily needs to describe the Tribology of contact phenomena. Consideration of continuum theory of rolling contact how a contact region is formed between rolling die and slab, and how the tangential force is distributed over the contact area with coefficient of friction is important. The central concern of numerical model is used in this work to indicate a set of equations, derived from the contact principle, that transfer the physical event into the mathematical equations including the laws of nature, such as newton’s laws, boundary conditions, state of stresses and their derivatives at particular time and locations. In this paper the elasticity stress behavior of rolling die contact with slab for number of cyclic loads is modeled. The model is including new proposed constitutive equations for discontinuity of the velocity, pressure distribution in rolling contact from the enter side to exit side of the neutral point. To verify the model, finite element simulation and experimental data from the literature are considered. The results show good agreement with finite element simulation and experimental data.

Authors: Itapu Srikanth , Borra Vamsi , Mossayebi Faramarz
Published: October 2018

This paper presents computational study of non-stoichiometric nickel oxide in a 32-cell NiO system to model and validate localized heating effects due to nanosecond laser irradiation. Variation in Bandgap of NiO is studied as a function of varying concentrations of native defects ranging from 0 to 25%. It is observed that there is a slight increase in the bandgap from 3.8 eV for stiochiometric NiO to 3.86 eV for Ni-rich NiO and to 3.95 eV for O-rich NiO. It is hence deduced that the experimental laser irradiation leads to simultaneous reduction of Ni2+ ions and oxidation of NiO as the number of laser pulses increase. As well, a detailed study on the effects of doping nickel family elements, i.e. palladium (Pd) and platinum (Pt) in stoichiometric NiO is presented. A bandgap decrease from 3.8 eV for pure NiO to 2.5 eV for Pd-doping and 2 eV for Pt-doping for varying doping concentrations ranging from 0–25% Pd, Pt respectively is observed.

Published: October 2018

Diabetes mellitus, a disease arising by the deficiency of insulin hormone or its inability of usage, affects carbohydrate, lipid and protein metabolism, and destruct variety of the tissues. A strong antioxidant and anti-inflammatory agent; resveratrol has a high potential to prevent or treat the pathogenesis of diseases. This study was conducted to reveal the relationship between diabetes-induced oxidative stress and tissue inflammation with changes in antioxidant enzymes (cat, sod, gpx, and gst) and the components of insulin signaling pathway (insulin Rβ, irs-1, pi3k, akt, mtor) in kidney tissues. Additionally, the effects of resveratrol on these parameters were evaluated. Male Wistar rats were randomly divided into four groups; (1) control/vehicle; (2) control/20 mg/kg resveratrol; (3) diabetic/vehicle; (4) diabetic/20 mg/kg resveratrol. Results demonstrated down-regulation of antioxidant enzymes in the kidney tissues of diabetic rats and this situation was devoted partially to the reduced expression of nfκb. Moreover, the components of renal insulin signaling elements were up-regulated in diabetic rats, and resveratrol treatment decreased this sensitization towards the control state. In conclusion, resveratrol improved diabetes-induced renal oxidative stress and inflammation partly due to healing action on renal antioxidant enzymes and insulin signaling pathway components.

Complications Associated with Volar Locking Plate Fixation of Distal Radial Fractures
Authors: Alter Todd H. , Ilyas Asif M.
Published: October 2018

* Volar locked plating is the most frequently utilized method for internal fixation of distal radial fractures.

* The overall complication rate for volar plating of distal radial fractures appears to be relatively low compared with other operative fixation methods.

* Carpal tunnel syndrome is the most commonly reported complication. However, this may occur after a distal radial fracture regardless of treatment method, with reported rates ranging from 0% to 20% with conservative management and 0% to 14% with volar plating.

* Extensor tendon rupture has been reported at rates of 0% to 4% and is the most frequent complication requiring plate removal.

* Variable-angle volar locking plates may be associated with fewer implant-related complications as a result of their greater degree of screw placement customization compared with fixed-angle volar locking plates.

edilmesi, hastanın sosyo-demografik özellikleri gibi pek çok özelliğinin yanı
sıra sunulan hizmetin kalitesi ile ilişkilidir. Bu çalışma ile hastanenin
tekrar tercih edilmesinde hizmetin kalitesinin göstergesi olarak düşünülen
“doktor”, “fiziki olanak”, “yemek” ve “diğer personelden” duyulan memnuniyet
düzeylerinin ikametgah durumuna göre probit regresyon analizi ile açıklanması
hedeflenmiştir. Araştırmanın örneklemine Kırıkkale Üniversitesi Tıp Fakültesi
Hastanesi servislerinde yatan 397 hasta dahil edilmiştir. Hastalar tabakalı
rasgele örnekleme yöntemi ile belirlenmiştir. Yapılan probit regresyon analizinde
oluşturulan genel modelde; hastaların hastaneyi tekrar tercih etmesinde
“doktor” faktöründen duyulan memnuniyet istatistiksel olarak önemli bulunurken
“yemek”, “diğer personel” ve “fiziki olanak” faktörlerinden duyulan memnuniyet
istatistiksel olarak önemsiz bulunmuştur. Ancak bu faktörlerin tek başına
hastanenin tekrar tercihindeki etkisini görmek için elde edilen probit
modellerde yemek dışında diğer faktörlerin anlamlı olduğu sonucuna
ulaşılmıştır. Bu çalışmanın sonucunda, yatılı olarak tedavi gören hastaların
“doktor” faktöründen duydukları memnuniyet arttıkça hastaneyi tekrar tercih
etme eğiliminin arttığı görülmüştür. Ayrıca ikametgah durumuna göre ise il
merkezinde ikamet eden hastaların il merkezi dışında ikamet edenlere göre daha
yüksek olasılıkla hastaneyi tekrar tercih edebilecekleri belirlenmiştir.

Core Ideas

Removal of aboveground biomass may affect soil C and N under forage sorghum.

Effect of cover crop and N on soil C and N and sorghum biomass were examined.

Soil organic C, soil total N, and sorghum biomass were greater with vetch–rye than other cover crops.

Ammonium‐N was greater with rye and nitrate‐N greater with vetch and vetch–rye.

Vetch–rye can enhance soil C and N storage, N availability, and forage sorghum biomass.

Sustaining soil C and N under bioenergy forage sorghum (Sorghum vulgare Pers.) may require cover crop C and N inputs. We evaluated the effect of cover crop (hairy vetch [Vicia villosa Roth], rye [Secaele cereale L.], hairy vetch–rye mixture, and the control [no cover crop]) and N rate (0 and 90 kg N ha–1) to forage sorghum on soil C and N. Soil samples collected from the 0‐ to 30‐cm depth after sorghum harvest in the autumn were analyzed for soil organic C (SOC), total N (STN), NH4–N, and NO3–N contents from 2010 to 2014 in the southeastern United States. Cover crop biomass and C and N contents were 60% greater with vetch–rye than rye and the control in 2013 and 2014. Forage sorghum biomass was 23% greater with vetch–rye than rye and vetch in 2012 and 7% greater with 90 than 0 kg N ha–1. At 0 to 5 and 0 to 30 cm, SOC was 16% greater with vetch–rye than rye and vetch and STN 15% greater with vetch, rye, and vetch–rye than the control at 0 kg N ha–1. Compared with other cover crops, NH4–N content at 5 to 15 cm was 40% greater with vetch and rye and NO3–N content at 0 to 30 cm was 20% greater with vetch and vetch–rye in 2011 and 2012. Because of increased C and N inputs, hairy vetch–rye cover crop mixture can enhance soil C and N storage, optimize N availability, and sustain forage sorghum biomass compared with other cover crops.

Core Ideas

More information is needed to improve late‐season bermudagrass control strategies in the Central Plains region of the United States.

A single autumn application of glyphosate reduces bermudagrass cover the following spring.

Bermudagrass control with a single autumn application of glyphosate was not improved by adding fluazifop, mesotrione, or both.

Multiple summer applications of glyphosate (N‐(phosphonomethyl)glycine) are commonly recommended for bermudagrass (Cynodon spp.) control. However, this regime results in an extended period of displeasing and nonfunctional turfgrass, and is not ideal for spring establishment. An autumn glyphosate application prior to winter dormancy can control bermudagrass and may benefit spring establishment projects. However, research is needed to more precisely define the parameters of efficacious late‐season herbicide applications for bermudagrass control as it transitions into dormancy. Therefore, our objective was to examine late‐season bermudagrass removal using combinations of glyphosate, fluazifop‐p‐butyl (fluazifop) (Butyl (R)‐2‐[4[[5‐(trifluoromethyl)‐2‐pyridinyl]oxy]phenoxy]propanoate), and mesotrione (2‐(4‐methylsulfonyl‐2‐nitrobenzoyl)‐1,3‐cyclohexanedione). Experiments were initiated in October 2013 at the Rocky Ford Turfgrass Research Center in Manhattan, KS, on mature ‘Midlawn’ hybrid bermudagrass [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt‐Davy], and at Stagg Hill Golf Course in Manhattan, KS, on mature common bermudagrass [C. dactylon (L.) Pers.]. Seven herbicide treatments containing combinations of glyphosate, fluazifop, and mesotrione were evaluated. Green bermudagrass cover (0–100%) was visually estimated when treatments were applied and every 14 d after application. Only treatments containing glyphosate reduced the green cover of bermudagrass at each site the following year. Across all ratings dates and locations, adding mesotrione, fluazifop, or both to glyphosate did not further reduce green bermudagrass cover. Overall, results indicate that a single autumn application of glyphosate prior to bermudagrass dormancy reduces bermudagrass cover the following spring. The significant reduction at spring green‐up may allow turf managers to make additional applications in the spring for increased control before spring establishment.
The Effect of Fallow Tillage Management on Aeolian Soil Losses in Semiarid Central Anatolia, Turkey
Authors: Nouri Amin , Youssef Feras , Basaran Mustafa , Lee Jaehoon , Saxton Arnold M. , Erpul Gunay
Published: October 2018

Core Ideas

Eliminating fallow tillage increased the natural plant cover at the soil surface.

Increased natural plant cover did not significantly decrease the aeolian soil losses.

Event‐based vertical distribution of soil losses were related to the upwind plant characteristics.

Accounting for plant configuration improved the prediction of vertical soil flux distribution.

In semiarid Central Anatolia Turkey, winter wheat (Triticum aestivum L.) planted under a conservation tillage system undergoes a no‐till fallow phase to reduce aeolian soil losses by maintaining the natural plant cover. This research was conducted to investigate the effectiveness of natural vegetation cover in relation to tillage‐induced soil surface properties in reducing the wind erosion during the fallow periods. Climatic parameters at experimental plots subjected to no fallow tillage (NFT) and conventional fallow tillage (CFT) (disk) managements were measured and friction velocity (u*) and aerodynamic roughness (z0) over four high wind events (wind velocities >5.7 ms−1 at 2 m high) were determined. Sediment fluxes at each management were measured using 20 sampling posts each holding five vertically placed sediment traps. Spatial dynamics of soil fluxes were related to the soil surface properties and the vegetation characteristics (coverage and configuration). Spatial variations in upwind vegetation characteristics were significantly (p < 0.05) related to the mass fluxes up to 40 cm above the soil surface. However, greater vegetation cover in NFT did not result in significant reductions in mass transport rate compared with CFT. This can be explained by substantially greater (>360%) loose material in NFT due to the dissipation of wheat residue during the early fallow period (23% in late March) and longer transport distance due to a lower surface roughness. These results corroborate that the elimination of fallow tillage alone may not generate sufficient natural vegetation cover to effectively reduce aeolian soil losses in fallow periods of winter wheat cropping systems.

Core Ideas

Establish a common threshold in P saturation across a geographic diversity of soils.

Predict water‐soluble P from soil P storage capacity to guide fertilizer strategies.

Relate runoff P concentration with soil P storage capacity.

Loss of legacy soil phosphorus (P) due to historical over‐application of fertilizers and manures can result in eutrophication of water bodies. The soil P storage capacity (SPSC) has been proposed as a tool to estimate the capacity of humid region soils to act as either sinks or sources of P to runoff or leaching. The SPSC is based on a threshold molar ratio of extractable P/(Al+Fe), called the soil P saturation ratio (PSR), above which water‐soluble P abruptly increases. Objectives were to (i) document consistency of the threshold PSR for a wide geographic range of acid soils, (ii) determine applicability of a SPSC vs. water‐soluble P predictive equation to soils from various regions, and (iii) relate SPSC with water quality parameters. Surface samples were collected from acidic, humid‐region soils encompassing multiple physiographic provinces of the United States. Water quality data, including dissolved reactive P and total P, were obtained from various study sites. Phosphorus, Fe, and Al in Mehlich 3 solutions were determined, and PSR and SPSC calculated. The threshold PSR based on 186 samples is 0.1, indicating a common threshold across the geographic range of this study. Phosphorus concentrations in runoff related closely with SPSC, PSR, and M3‐P values of soils that were the source of the runoff. However, SPSC has the additional potential of estimating extent of legacy P loss at excessive concentrations for soils of eastern and central United States. Results support general applicability of PSR and SPSC for acid soils.
Working hours reduction, financial constraints, and employment: evidence from Korean firms
Authors: Ahn Ji-Young
Published: October 2018

This study analyzes the effect of reducing working time to a 40-hour week standard on employment, using the data of 1,961 publicly traded firms in Korea. The objective of the study is to empirically estimate the economy-wide effect of this working hours reduction on employment in Korea. This paper also attempts to uncover the effect of financial constraints, defined as the degree of accessibility to finance, on employment stability or sustainability. Some economic theories suggest that financial constraints have mixed or conflicting effects on employment. Building on labor and finance literature such as Garmaise (2007), easing financial constraints helps firms to optimally substitute capital for labor, thereby decreasing employment. Likewise, financially constrained firms are limited by the availability of internal funds, and a decrease in the external financing cost will increase firm-level human resource investment, such as employment. Using a longitudinal data on publicly listed companies in Korea, the author examines variations in the timing of implementing the working hours reduction in terms of establishment size to see if the effect of working hours reduction on employment differs with the degree of financial constraints of firms. This paper finds that the economy-wide effect on employment of work-hours reduction is positive, approximately 3.5% increase in employment. The results, however, show that there is no effect of the working hours reduction on employment in less financially constrained firms or larger corporations, whereas a substantial positive effect on employment is in smaller firms or financially constrained firms, supporting the Garmaise’s prediction.
Hypertrophic cardiomyopathy: Sudden cardiac death risk stratification in adults
Authors: Jordà Paloma , García-Álvarez Ana
Published: October 2018

[first paragraph of article]Sudden cardiac death (SCD) is a devastating and often unpredictable complication of hypertrophic cardiomyopathy (HCM) that may occur as the initial disease presentation, frequently in asymptomatic or mildly symptomatic young people. Until 2000, only small series of patients examining predictors of SCD had been published, with a selection bias towards severe disease. Subsequently, larger series that are more representative of the HCM spectrum have shown that the annual SCD rate is less than 1%, and that there are subgroups of patients with a clearly higher risk.
