Nonlinear autoregressive-moving average-L2 (NARMA-L2) controller for multivariable ball mill plant
Authors: Bustamante Rodrigo de A. , Bastos Beatriz S. M. , de Oliveira Juan S. , Santos Brunno F.
Published: August 2021

Mineral processing facilities concern an enormous amount of dynamically complex unit operations (due to nonlinearities), for instance ball mill system. Normally, these processes need multivariable controllers to smooth actions by designing for plant constraints such as deadtimes and dynamics interactions. The present work presents a comparison between a classical PI and nonlinear moving average autoregressive-linearization level 2 (NARMA-L2) controllers based on artificial neural network (ANN) for a ball mill system. The manipulated variables of this plant are the rotation velocity (Vr) and the feeding weight (Wf), while the controlled parameters are the hold up (HU) and the mass fraction under 45 μm (P45). The simulation was built in the MATLAB software (Simulink), comparing the actions of PI and NARMA-L2 controllers in the face of operational changes in specific regions (constraints). The performance of proposed controllers was verified by the integral of absolute error (IAE), integral of squared error (ISE), or the integral of time-weighted absolute error (ITAE). The results of simulation showed the validity of the model obtained and the control technique proposed in this paper, which contributes to studies of multivariate controller designs for ball mills with significant applications. Additionally, this paper brings a first hybrid approach (PI/NARMA-L2) with successful implementation described in the literature.

Objectives

We describe an approach for analyzing failures in diagnostic processes in a small, enriched cohort of general medicine patients who expired during hospitalization and experienced medical error. Our objective was to delineate a systematic strategy for identifying frequent and significant failures in the diagnostic process to inform strategies for preventing adverse events due to diagnostic error.

Methods

Two clinicians independently reviewed detailed records of purposively sampled cases identified from established institutional case review forums and assessed the likelihood of diagnostic error using the Safer Dx instrument. Each reviewer used the modified Diagnostic Error Evaluation and Research (DEER) taxonomy, revised for acute care (41 possible failure points across six process dimensions), to characterize the frequency of failure points (FPs) and significant FPs in the diagnostic process.

Results

Of 166 cases with medical error, 16 were sampled: 13 (81.3%) had one or more diagnostic error(s), and a total of 113 FPs and 30 significant FPs were identified. A majority of significant FPs (63.3%) occurred in “Diagnostic Information and Patient Follow-up” and “Patient and Provider Encounter and Initial Assessment” process dimensions. Fourteen (87.5%) cases had a significant FP in at least one of these dimensions.

Conclusions

Failures in the diagnostic process occurred across multiple dimensions in our purposively sampled cohort. A systematic analytic approach incorporating the modified DEER taxonomy, revised for acute care, offered critical insights into key failures in the diagnostic process that could serve as potential targets for preventative interventions.

Published: August 2021

A growing trend has been observed in recent research in wireless communication systems. However, several limitations still exist, such as packet loss, limited bandwidth and inefficient use of available bandwidth that needs further investigation and research. In light of the above limitations, this paper uses adaptive modulation under various parameters, such as signal to interference plus noise ratio (SINR), and communication channel’s distances. The primary goal is to minimize bit error rate (BER), improve throughput and utilize the available bandwidth efficiently. Additionally, the impact of Additive White Gaussian Noise (AWGN), Rayleigh and Rician fading channels on the performance of various modulation schemes are also studied. The simulation results demonstrate that our proposed technique optimally improves the BER and spectral efficiency in the long-range communication as compared to the fixed modulation schemes under the co-channel interference of surrounding base stations. The results indicate that the performance of fixed modulation schemes is suitable only either at high SINR and low distance or at low SINR and high distance values. Moreover, on the other hand, its performance was suboptimal in the entire wireless communication channel due to high distortion and attenuation. Lastly, we also noted that BER performance in the AWGN channel is better than Rayleigh and Rician channels with Rayleigh channel exhibiting poor performance than the Rician channel.
Experimental study on the behavior of MSE wall having full-height rigid facing and segmental panel-type wall facing
Authors: Won Myoung-Soo , Langcuyan Christine P. , Choi Gwan-Hee
Published: August 2021

The amount of the lateral displacements on the mechanically stabilized earth (MSE) wall depends on the reinforcement extensibility and length, reinforcement-to-facing connection, and the wall facing, among others. In this study, the deformation behavior of MSE wall models was focused considering two types of wall facing and three types of reinforcement. A series of small-scale model tests were undertaken on the MSE wall having a full-height rigid (FHR) facing and a segmental panel-type (SPT) wall facing. At the same time, the models were using discrete geogrids, geosynthetic strips, and steel rods as reinforcement. The results showed that the geogrids-reinforced MSE wall with FHR facing exhibited the highest load capacity with the least vertical displacements. The MSE wall models with steel reinforcements generally exhibited the least lateral displacements at wall facing than those with geosynthetics reinforcements. Finally, the results showed that MSE wall models with FHR facing have generally lesser lateral displacements at the wall facing compared to those with SPT wall facing.
Prediction of total landslide volume in watershed scale under rainfall events using a probability model
Authors: Wu Chun-Yi , Chou Po-Kai
Published: August 2021

This study established a probability model based on the landslide spatial and size probabilities to predict the possible volume and locations of landslides in watershed scale under rainfall events. First, we assessed the landslide spatial probability using a random forest landslide susceptibility model including intrinsic causative factors and extrinsic rainfall factors. Second, we calculated the landslide volume probability using the Pearson type V distribution. Lastly, these probabilities were joined to predict possible landslide volume and locations in the study area, the Taipei Water Source Domain, under rainfall events. The possible total landslide volume in the watershed changed from 1.7 million cubic meter under the event with 2-year recurrence interval to 18.2 million cubic meter under the event with 20-year recurrence interval. Approximately 62% of the total landslide volume triggered by the rainfall events was concentrated in 20% of the slope units. As the recurrence interval of the events increased, the slope units with large landslide volume tended to concentrate in the midstream of Nanshi River subwatershed. The results indicated the probability model posited can be used not only to predict total landslide volume in watershed scale, but also to determine the possible locations of the slope units with large landslide volume.
Characteristic and paleoenvironment significance of microbially induced sedimentary structures (MISS) in terrestrial facies across P-T boundary in Western Henan Province, North China

Published: August 2021

We report varied microbially induced sedimentary structures (MISS), and other sedimentary surface textures, from the Induan (Early Triassic) Sunjiagou Formation and Liujiagou Formation in the Xingyang, Dengfeng, Jiyuan and Yiyang areas, western Henan Province, North China. Microanalysis shows that these MISS are characterized by a U-shaped structure, thin clayey laminae, and discontinuous mica sheet that are arranged parallel to the bedding plane, as well as directionally oriented quartz grains floating in lamina, which are indicative of a biogenic origin. The MISS of the studied area were probably affected by four main factors, including the end-Permian mass extinction, the megamonsoon, the adapted sedimentary environment, and the sediment supply, and they possess significant stratigraphic correlation. Abundant microbial-related sedimentary structures from the study area indicate that continental ecosystems were severely devastated in the aftermath of the Permian-Triassic biocrisis. These sedimentary structure assemblages, including MISS, red beds, conglomerate layers, and calcareous concretions in the western Henan Province, show a specific, post-extinction continental ecosystem that was characterized by microflora dominance, monotonous and rare fossils, extreme hot climate, soil ecosystem devastation, and poor vegetation.
Self-deprecating humor and task persistence: the moderating role of self-defeating humor style
Authors: Cheng David
Published: August 2021

Over the past two decades a significant body of research has examined the effects of individual differences in humor style or humor occurrences (e.g. specific jokes, memes) on behavior. However, research examining whether these individual differences in humor styles influence the effects of humor occurrences on work behaviors has been scant. Drawing on Conservations of Resources (COR) theory, this paper seeks to fill this gap by examining one form of humor, self-deprecating humor, and its interaction with self-defeating humor style to influence task persistence behavior. Findings from an experimental study of 124 management students show that self-deprecating humor can bolster a person’s persistence at an assigned task. Findings also show that individual differences in self-defeating humor style influence the relationship between self-deprecating humor and persistence. Individuals low in self-defeating humor style show a significant increase in persistence while those high in self-defeating humor style did not show any significant increase.
Psychometric properties of the Comic Style Markers – Portuguese version: applying bifactor and hierarchical approaches to studying broad versus narrow styles of humor
Authors: Moreira Paulo A. S. , Inman Richard A.
Published: August 2021

Given the relevance of humor for psychosocial assessment and promoting positive functioning, it is important to understand the relationship between humor and personality. A recent framework for describing individual differences in humor posits eight comic styles that can be measured using the Comic Style Markers (CSM). In total, 665 Portuguese adults (Mage = 32.1 years) completed the CSM and Cloninger’s Temperament and Character Inventory. CFAs supported modeling the CSM as a bifactor model. Bifactor indices suggested a general humor factor could be interpreted as a unidimensional construct, but that CSM items are multidimensional. A hierarchical analysis showed the styles could be represented at several levels of abstraction. A SEM analysis suggested certain styles had distinct associations with personality dimensions. These findings suggest that the use of certain styles (namely wit, sarcasm, and cynicism) was related to individual differences in temperament and character beyond a person’s overall humor potential.

Published: August 2021

Less vascular resistance, higher vascular permeability and improved cardiac output include anatomical and physiological changes related to pregnancy. These are needed to accommodate an increase in plasma volume and ensure significant organ infusion. Nevertheless, increases in oestrogen levels may lead to an increase in the risk of coagulation and thrombosis. Increased levels of progesterone increase the risk of thrombosis due to vasodilation, vascular stasis and edoema in these situations. The increased resistance in preeclampsia maternal systemic blood arteries can create high blood pressure that can interfere with blood flow in numerous organs (including liver, kidneys, brain and placenta). The risk of issues such as pulmonary edoema, placental abruption, pneumonia of aspiration, renal failure, hepatic failure and stroke in pregnant women is increased by Preeclampsia and eclampsia. Some peripheral neuropathies (carpal tunnel syndrome, peripheral facial palsy) and central neurological conditions (seizure, migraine, stroke, epilepsy) may become more common during pregnancy because of the exacerbation of the pre-existing neurologic condition or the onset of neurological disturbance caused by pregnancy physiological changes (such as headache or vascular disorders). During the three trimesters of pregnancy, neurological disorders are both peripheral and central. Therefore, an early and correct diagnosis is required to improve pregnancy care, treatment and perinatal outcomes. The aims of this paper are to identify, define and manage the most prevalent peripheral and centrally occurring neurological disorders in the pregnancy.

Authors: Zehravi Mehrukh , Maqbool Mudasir , Ara Irfat
Published: August 2021

Polycystic ovarian syndrome (PCOS) is the most frequent endocrine disorder among women of reproductive age. Some of the indications and symptoms of PCOS include amenorrhoea, hirsutism, infertility, obesity, acne vulgaris and androgenic alopecia. PCOS is a crippling condition that affects a woman’s identity, mental health and overall quality of life (QOL). In persons with PCOS, anxiety and sadness are assumed to be multifactorial. According to some specialists, physical symptoms like acne, hirsutism and obesity have been linked to psychiatric morbidities. Many aspects of it remain unknown, including its cause, progression throughout life, symptom spectrum and level of morbidity. PCOS is a complex disease that has an impact on many aspects of a person’s health, including their mental health. Anxiety and depression are three times as common in PCOS patients as in non-PCOS people. Anxiety and depression symptoms are also more common and more intense in those with PCOS. There isn’t enough research on the prevalence of anxiety and depression in patients with PCOS. It’s unclear what causes persons with PCOS to be more anxious and depressed. It could be the result of PCOS symptoms, hormonal changes, or a combination of factors that are currently unclear. Our review article will help to highlight the most recent research on anxiety and depression in PCOS women.

Published: August 2021

In the current scenario treatment of industrial waste water is big challenge especially waste water that contain high organic load. Hydrogen peroxide assisted electrocoagulation (EC) process provides better result to treat highly polluted wastewater as compared to EC alone. However, hydrogen peroxide is well known as a strong oxidant, which cast a potential threat to human health. To overcome this problem hydrogen peroxide has been used here for treatment of wastewater in small quantity, and that consume during the process. Therefore the harmful effect of hydrogen peroxide in human and aquatic life could be minimized. This work is an attempt to treat biodigester effluent (BDE) using H2O2 assisted EC processes with respect to chemical oxygen demand (COD) and color reductions. To perform this experiment both iron and aluminum electrodes are used as an electrode material in the presence of H2O2. In case of iron electrode the maximum COD and color reduction efficiency of 98.3 and 83.6% was achieved at the cost of 1.5 Wh/dm3 energy consumption while maximum COD and color removal efficiency of 96.8 and 77.1% with 1.7 Wh/dm3 of energy consumption was observed in the aluminum electrode based EC process. A part from this conventional biological process (i.e., activated sludge treatment, ponds, and lagoon etc.) and physiochemical treatment process (i.e., coagulation, adsorption) provided treatment efficiency of 40–80% hence hydrogen peroxide assisted EC process should a better choice to treat distillery effluent. Furthermore, hybrid EC process was also performed with iron used as anode and aluminum as cathode in the presence of H2O2. Iron electrode based peroxi-EC process provided better result at optimum operating conditions; current density of 114 A/m2, initial COD concentration of 12,000 mg/dm3, initial pH of 7.3, H2O2 concentration of 120 mg/dm3, stirring speed of 120 rpm and electrolysis time of 90 min. The cost estimated for operation is 1.56 US $/m3. Finally, sludge analysis and cost optimization are also incorporated in this article.

Authors: Li MeiYu , Bilige Sudao , Zhang Run-Fa , Han Lihui
Published: August 2021

The (3 + 1)-dimensional Kadomtsev–Petviashvili–Boussinesq-like equation has certain advantages in solving engineering problems. In this paper, based on the generalized bilinear form, we successfully derived the diversity of exact solutions under certain constraints by using the symbolic computation Maple. These solutions have interaction wave solitons, cross-kink wave solitons, and bright-dark solitons. To ensure the accuracy of these solutions, we made a special selection of the parameters involved and made a three-dimensional graph, density graph, and contour graph to illustrate the dynamics of the solutions. The resulting solutions can be used for the study of certain phenomena in physics.

Published: August 2021

In this paper, we study a type of nonlinear hybrid Δ-difference equations of fractional-order. The main objective is to establish some stability criteria including the Ulam–Hyers stability, generalized Ulam–Hyers stability together with the Mittag-Leffler–Ulam–Hyers stability for the addressed problem. Prior to the stabilization processes, solvability criteria for the existence and uniqueness of solutions are considered. For this purpose, a hybrid fixed point theorem for triple operators and the Banach contraction mapping principle are applied, respectively. For the sake of illustrating the practical impact of the proposed theoretical criteria, we finish the paper with particular examples.
The use of blocking and inhibition training in processing instruction
Authors: Henry Nick
Published: August 2021

Previous research has suggested that L2 learners often use non-target processing strategies to understand sentences, but that these strategies can be changed through targeted instruction that directs their attention to different linguistic forms or structures. The present study explores the effects of pretraining ‘blocking’ practice—a novel type of training designed to help learners inhibit the application of a strict word-order based processing strategy—prior to receiving a traditional Structured Input (SI) training focused on OVS word order and accusative case markers in German. The study compares three groups of third-semester German learners who completed three different activities in one training session: (1) SI with blocking practice (+BP), (2) SI preceded by explicit information (+EI), and (3) SI without EI or blocking practice (−EI). The effects of training were measured by sentence-level interpretation and production tasks administered as a pretest, posttest, and four-week delayed posttest. Learner performance was also assessed during training. Results in all assessment measures indicated that EI was most effective, but that blocking practice lent a slight advantage over −EI groups during and after training. These results are discussed in the context of studies on processing instruction and learned attention.
Efficacy and tolerability of Lavandula angustifolia in treating patients with the diagnosis of depression: a systematic review of randomized controlled trials
Authors: Shamabadi Ahmad , Akhondzadeh Shahin
Published: August 2021

Pharmacotherapy is the conventional treatment for depression, with only half of the patients responding to the first trial of monotherapy with first-line medicines. One way to overcome this resistance is to use complementary and alternative medicine. The antidepressant effects of Lavandula angustifolia, which is commonly called lavender, have been investigated in previous studies. This study aims to provide the first systematic review of lavender in treating patients with depression diagnosis. ISI Web of Science, Scopus, PubMed, Embase, PsycINFO, Google Scholar, and three trial registries were searched until May 2020 to find randomized controlled trials on lavender for depressed patients. The primary outcome was difference between the intervention and control groups in changing depression scores from baseline to endpoint. The included studies were assessed for effect size and methodological quality. Seven clinical trials were identified, in which 852 patients were studied. In six trials, the effectiveness of lavender in treating depression was reported, as being more pronounced adjunct to a typical antidepressant in one study. Significant reported side effects include headaches and eructation. Lavender is beneficial, tolerable, and safe in treating depression. Despite obtaining promising results, they are not enough to recommend prescribing lavender to depressed patients. Further high-quality, large-scale studies for rectifying the shortcomings of existing studies are recommended.

Authors: Bansal Poornima , Kannarpady Janardan Sujatha , Shetty Prashanth
Published: August 2021

Objectives

Hypertension (HTN) is considered as chronic medical condition. Because of the increased complications associated with the conventional medicine, the effects of naturopathic modalities were emphasized to prevent and minimize those adverse effects. This study was done to assess the immediate effect of neutral spinal compress on heart rate variability and blood pressure and thereby to substantiate the clinical understanding of its effect in hypertensive individuals.

Methods

Hundred hypertensive individuals were recruited for the study. Subjects were assessed for blood pressure (BP) and Heart Rate Variability (HRV) before and immediately after the intervention of 20 min.

Results

Result shows significant reduction in mean heart rate (HR) (p<0.001), low frequency (LF) (p<0.001), low frequency/high frequency (LF/HF) (p<0.001), systolic blood pressure (SBP) (p<0.001) and diastolic blood pressure (DBP) (p<0.001) and significant increase in mean R-R interval (Mean RR) (p<0.001) and high frequency (HF) (p<0.001) components of Heart Rate Variability after neutral spinal compress intervention.

Conclusions

The results of the study reported that full neutral spinal compress reduces the sympathetic tone and shifts the Sympatho-vagal balance in favor of parasympathetic dominance and hence it can be concluded that neutral spinal compress can be effectively used in the management of hypertension.

FBMC OQAM: novel variant of OFDM
Authors: Tiwari Shiv Om , Paulus Rajeev
Published: August 2021

Orthogonal frequency division multiplexing (OFDM) revolutionizes the transmission technologies, including, optical as well as wireless communication. In OFDM the orthogonal nature of carriers makes it very good technique for data transfer. Still the out-of-band (OOB) radiation in OFDM leads to inter symbol interference (ISI) and bit error rate (BER) goes down. Moreover amplitude variations of the subcarriers lead to power variations and peak-to-average power ratio (PAPR) problem. To overcome these issues a novel filter bank multicarrier (FBMC) scheme is proposed, where each carrier is allowed to pass through to a separate filter and orthogonality among subcarriers is relaxed. Thus FBMC has better OOB and PAPR performance. In this work, we also have evaluated the PAPR performance by the simulation results. For the improvement of PAPR nonlinear companding scheme along with clipping is presented. The hybrid technique (clipping + companding) parameters are set in such a way that PAPR is reduced while signal power remains constant. Results are also compared with recent methods and it has been found that the proposed technique preforms better than other chosen techniques.
Performance analysis of a hybrid FSO–FO link with smart decision making system under adverse weather conditions
Authors: Mohapatra Pradyut , Singh Garima , Singh Anjali , Kaur Gurjit
Published: August 2021

Optical wireless communication systems employing free-space optical (FSO) links utilize modulated lasers to transmit information. FSO–fiber optic (FO) link provides an alternative possible way in scenarios where infrastructures employing optical fibers are widely destroyed due to disasters or when difficulties are faced during the installation of FO links. Furthermore, the link is integrated with decision-making ability. To encounter the distortions in the received signal carrier-suppressed return-to-zero modulation format has been used. FSO–FO hybrid link has been compared with simple FSO channel. The terrestrial links depend strongly on weather conditions as optical beams propagate through the atmosphere. Atmospheric attenuation could affect the FSO channel and has been considered to analyze the performance of the designed system.

A TANULMÁNY CÉLJA

Az aktív sportolás mögött húzódó motivációk feltérképezésének fontos szerepe van a sportfogyasztás minél pontosabb megértésében. Kutatásunk célja egy olyan sportolási motivációkat mérő skála kialakítása volt, amivel átfogóan fel tudjuk mérni a magyar lakosság rendszeresen sportoló hányadának sportolási motivációit. Ez a megközelítés újdonságot jelent más sportmotivációs skálakutatásokhoz képest, mivel nem versenysportolókra, hanem az átlagemberek sportolási motivációira fókuszál.

ALKALMAZOTT MÓDSZERTAN

Kutatásunk során saját skálát fejlesztettünk, amit az EFOP-3.6.2-16-2017-00003: „Sport- Rekreációs- és Egészséggazdasági Kooperációs Kutatóhálózat létrehozása” című projekt keretében végzett magyar lakossági sportfogyasztási felméréseken teszteltük. Alapjául egy 2000 fős mintán végezett személyes megkérdezés szolgált, ami reprezentatívnak tekinthető a 15-74 éves magyar lakosságra nem, korcsoportok (10 éves intervallumok) és a lakóhely régiója alapján. A keletkező adatokon a skála mérési dimenzióinak kialakításához faktorelemzést alkalmaztunk, majd meggyőződtünk a keletkező faktorok megfelelő belső megbízhatóságáról. Utolsó lépésben a mintánkon klaszterelemzést végeztünk, hogy meggyőződhessünk skálánk gyakorlati használhatóságáról a magyar lakosság sportmotivációs mintázatainak megállapításához.

LEGFONTOSABB EREDMÉNYEK

Skálánk alkalmasnak bizonyult a hétköznapi emberek sportolása mögötti motivációk mérésére három különböző dimenzió mentén is. Segítségével a magyar lakosság körében sikerült feltárnunk hat különböző sportolási motivációkkal rendelkező csoportot, akik a relaxálók, az elkötelezett testedzők, a közösségi sportolók, az átlagos sportfogyasztók, az önmaguknak megfelelni akarók és a magányos testformálók. Skálánk gyakorlati alkalmazhatóságát bizonyítja, hogy az elkülönített csoportok sportfogyasztása több szempont szerint is jelentős eltéréseket mutat.

GYAKORLATI JAVASLATOK

A kutatásunk során kifejlesztett sportmotivációs skála segítségével a sporthoz kapcsolódó vállalatok pontosabban tudnak szegmentálni és célcsoportokat meghatározni, ami megteremtheti a jobb pozícionálás lehetőségét is. A számos szereplő és a kiélezett verseny miatt ez kulcskérdést jelenhet adott sportvállalat sikeressége szempontjából. Alkalmas azonban a társadalmi célú üzenetek célzott eljuttatásának segítésére is.

Por ello, en este estudio se determinó la eficiencia técnica (ET) de las universidades públicas peruanas mediante el análisis envolvente de datos (DEA) y, además, se analizaron las relaciones entre la experiencia y calidad de las instituciones, y la ET. El estudio abarcó las 42 universidades públicas registradas para el año 2016, a la cuales se les midieron un insumo y dos productos. Se concluyó que las universidades públicas peruanas presentan funciones de producción de rendimientos constantes a escala (ETG promedio= 56.8%), lo que sirvió de base para clasificar a las instituciones en cuatro categorías según sus orientaciones estratégicas (alta o baja) hacia la investigación o masificación educativa; asimismo, se comprobó que la ET no se relaciona con la experiencia o la calidad de la institución educativa.
Are esports bettors a new generation of harmed gamblers? A comparison with sports bettors on gambling involvement, problems, and harm
Authors: Greer Nancy , Rockloff Matthew J , Russell Alex M T , Lole Lisa
Published: August 2021

Background and aims

Esports betting is expanding in popularity, yet little is known about who participates in this niche gambling activity. This study aimed to determine whether esports bettors are more vulnerable to harms and problems than gamblers engaged in traditional sports betting.

Methods

Data were collected from 298 regular esports bettors and 300 sports bettors (who regularly bet on traditional sports, but not esports). These groups were compared on demographics, gambling involvement, problem gambling, and gambling-related harms.

Results

Compared to sports bettors, esports bettors were more likely to be younger, university-educated, employed (lower income earners), and speak a non-English language at home. Esports bettors gambled on fewer traditional gambling activities in the last 12 months, but compared to sports bettors, gambled more frequently on some activities, were more likely to meet problem gambler criteria (64.8.% vs 17.3%), and experience at least one gambling-related harm (81.9% vs 45.3%). Being an esports bettor significantly predicted greater problem gambling severity and gambling-related harms. More frequent esports skin betting and skin gambling (on games of chance) were significant predictors of gambling problems amongst esports bettors.

Discussion and conclusion

The results provide preliminary evidence that esports bettors are more likely to experience gambling problems compared to their sports betting counterparts, potentially stemming from their involvement in emerging video-game related gambling products.

Due to their low-noise installation and relatively large axial capacity, screw piles have been proposed as an alternative foundation solution in dense sand for offshore renewable energy applications in deeper water. For this to occur, significant upscaling of onshore dimensions is required. Furthermore, the effects of certain geometric features on installation requirements are still not well understood. In this work, using the three-dimensional discrete-element method, the effects of base geometry, shaft diameter and helix pitch were investigated by simulating the full installation process prior to conducting axial compression and tension tests. The results of the investigation showed it is possible to optimise the geometry of the screw pile to reduce installation requirements, in terms of both vertical installation force (up to 61%) and installation torque (up to 39%), without reducing the axial capacity of the pile significantly.

Destinasyon pazarlamasında marka değeri ve ağızdan ağıza pazarlama, turist davranışlarını etkileyen en önemli pazarlama araçları olarak görülmektedir. Bu bağlamda, çalışmanın amacı turistler tarafından algılanan Tüketici Temelli Destinasyon Marka Değeri’nin (TTDMD) Ağızdan Ağıza Pazarlama’ya (AAP) etkilerini incelemektir. Bu amaç doğrultusunda; TTDMD boyutları (destinasyon farkındalığı, destinasyon imajı, algılanan kalite, destinasyon memnuniyeti ve destinasyon sadakati) ile AAP boyutları (negatif ve pozitif AAP) arasındaki etkileşimleri kapsayan teorik model önerilmiştir. Model, Fethiye destinasyonuna tatil yapmak amacıyla gelen 201 adet yerli turist üzerinden elde edilen verilerin analizi ile test edilmiştir. Verilerin elde edilmesinde anket tekniğinden yararlanılmıştır. Araştırma modelinde yer alan ölçüm modellerinin geçerliliği ve güvenilirliği sağlandıktan sonra AMOS 22.0 paket programından yararlanılarak hipotezler analiz edilmiştir. Yol analiz sonuçları önerilen modeli doğrulamakla beraber algılanan destinasyon kalitesi ve destinasyon sadakatinin pozitif AAP üzerinde güçlü bir etkisinin olduğunu ortaya koymuştur. Diğer taraftan negatif AAP’nin algılanan destinasyon kalitesinden olumsuz yönde etkilendiği de tespit edilmiştir.
Positioning Human Microbiome DTC Tests On the Search for Health, Data and Alternatives Amid the Financialisation of Life
Authors: Widmer Alexandra
Published: August 2021

Early during my fieldwork on the social life of the microbiome in Toronto, I was asked ‘Do you believe in microbiome testing?’ This question invited me to evaluate the science of the direct-to-consumer (DTC) test. In this Position Piece, I consider this question in a more expansive manner so as to position the test in its social and economic context. The distribution and public uptake of such a DTC test require scientific expertise but also marketing, capital investments, and clinical labour. This test requires consumers to do the work of stool collection and the reproductive labour of diet changes in their domestic spaces. I have learned that the microbiome is part of the quest for alternative ways of living and being healthy. Broadening the question to consider more than just the science expands the frame from one of scientific efficacy and individual consumption to one that considers the financialisation of health and the politics and environments of post-Pasteurian and post-industrial contexts.
Selection of optimal therapeutic modality for early-stage extranodal natural killer/T-cell lymphoma patients under the guidance of single-nucleotide polymorphism signature

The therapeutic modalities of early-stage and advanced extranodal natural killer/T-cell lymphoma (NKTCL) patients are completely different. The former is mainly radiotherapy with or without chemotherapy, while the latter relies on chemotherapy-based systemic treatment.1,2 According to Ann Arbor staging system, approximately 70% of the NKTCL patients are classified as early-stage cases who are promising to be cured.3 Considering NKTCL is sensitive to radiation but may be resistant to chemotherapy, the radiotherapy is considered to be the most important treatment for some early-stage patients with a satisfactory local control rate and could be used alone.4 However, systemic recurrence after radiotherapy in a portion of NKTCL patients seriously affects their long-term survival, and the first-line treatment combined with radiotherapy and chemotherapy is considered necessary. Therefore, the use of radiotherapy alone in early-stage NKTCL is still a controversial issue.5,6

Mesenchymal stem cells (MSC) represent a heterogeneous population with the capacity to self-renew and differentiate into different cell types. At the middle of the last century these cells initially were described in bone marrow (BM), thence this tissue has become the gold standard for obtaining and characterization of MSC. It is known that these cells are housed in specific areas called niches distributed throughout all body, where they contribute to tissue regeneration processes of self-tissue were they are located. However, finding an alternative source of CTM with the same characteristics that have showed in MO, but its obtention no represent a risk since the donor is essential to their use for therapeutic purposes. In this study we isolated mesenchymal stem cells from bone marrow, adipose tissue and Wharton’s jelly and they were compared in their characteristics in according to the standards of the International Society for Cellular Therapy (ISCT). The results showed that the morphology as well as adipogenic and osteogenic differentiation and also the expression of surface antigens (CD90, CD73, and CD105) from all tissues accomplished the standards, although Wharton’s jelly represented the best option.

Background. Schistosomiasis has been a community health problem in endemic areas. In Indonesia, it is caused by trematode Schistosoma japonicum, with snail Oncomelania hupensis lindoensis as its intermediate host. This disease is only found in three endemic areas in Central Sulawesi Province: Napu and Bada highlands, Poso Regency, and Lindu highland in Sigi Regency. Various schistosomiasis control efforts were accomplished for more than the last twenty years. However, the schistosomiasis prevalence in Indonesia still fluctuates. The study aimed to determine the effectiveness of the Peda’ team in the research area. Method. One strategy of schistosomiasis control by community empowerment, namely the Bada Model, was implemented in Bada highland, Poso Regency, Central Sulawesi Province, from May to November 2019. One of the model’s elements is the formation of the schistosomiasis control village team (namely Peda’ Team), which was trained about schistosomiasis control. After the training, they were assigned several duties, including schistosomiasis socialization to the village community, stool sample collection, snail habitat control, snail and rats survey, and assisting the mass drug administration. The evaluation was conducted in stool sample coverage and the snail habitat area. Results. The results showed an increase in stool sample collection coverage in the community, becoming more than 80% in almost all endemic villages. We found the decrease from 26 become three focus areas because of the active effort to control the schistosomiasis intermediate snail focus area. Based on the results can be concluded that the Peda team formation can support schistosomiasis control more useful in the research area Keywords: Schistosomiasis, Bada Model, Community Empowerment
TRANSFORMING THE HEALTHCARE SYSTEM: THE PUBLIC-PRIVATE HEALTHCARE DICHOTOMY IN INDIA IN THE ERA OF DIGITAL HEALTH
Authors:   The National University of Advanced Legal Studies (NUALS), Kerala, India, Samuel Liji
Published: August 2021

Digital health initiatives have become popular in all jurisdictions across the globe. The digital health move, though it is envisioned as a cost-effective way to ensure the availability of health care services especially for the people who live in rural areas, its success depends on the response of the health care system and the state control and regulation. India lacks a comprehensive statesponsored or state-regulated health care system and more than 70 percent of people utilise the private sector medical services. In this backdrop, the implementation of the National Digital Health Mission (NDHM), announced by the Government of India very recently, will be critical. Thus, this research paper strives to bring out the public-private disjunction in the availability and utilisation of public and private health care facilities, issues of health care financing and legal regulation of clinical establishments in the public and private sector. This study uses the doctrinal method and analyses the Five-Year Plans, National Sample Survey Reports, National Health Profile, National Health Accounts Estimates for India and other Government Reports and independent studies to detail the public-private dichotomy. However, this study finds limitations in presenting the current position of private health care service providers due to the unavailability of updated authoritative government reports/ studies/ surveys. On reviewing the currents trends in the public and private health care sector, the study finds that the private sector has surpassed the public sector in all means, including health provisioning, utilisation, and financing. The NDHM is a laudable initiative to ensure affordable health care to millions of people in India. However, any move to implement it, leaving the fundamental issue of deep-rooted public-private dichotomy existing in the healthcare sector will be detrimental. It will result in a digital divide in the public and private healthcare sector and gross violation of patients’ rights and mismanagement of health information.
