Published: June 2021

Al Mukarromah Mosque in Kampung Bandan, North Jakarta, Indonesia, is a religious tourism destination. The Mosque housed tombs of Islamic propagators, Habib Mohammad Bin Umar Al-Qudsi, Habib Ali Bin Abdurrahman Ba’alawi, and Habib Abdurrahman bin Alwi As-Syatiri. Pilgrims come to the Mosque to pray, due to its history. Tourism activity causes physical changes in the building of the mosque and the houses around it. Since the surrounding settlement is high-density, the changes in settlement need to be watched to ensure the sustainability of Al Mukarromah Mosque and the settlement. This article aims to observe the physical changes in housing as a result of the existence of the Al Mukarromah Mosque, which developed due to tourism activities. Data collection was carried out through interviews and literature studies. Data collected then translated into house plans before and after transformation. The data obtained were analysed using descriptive interpretative methods. Three aspects to analyse are building area, function, and material. The results show that only adjacent houses to Al Mukarromah Mosque benefit directly from religious tourism. Other parts of Kampung Bandan still maintain the characteristics of kampung or high-density settlement. Kampung Bandan lacks the necessary facilities such as public space to support religious tourism.

Bus rapid transit system as a potent agent for transit-oriented development: A study of Transjakarta passengers’ mode shift
Authors: Prayogi L , Hanton D
Published: June 2021

Recently there has been discussions on the role of bus rapid (BRT) transit in transit-oriented development (TOD). This article explores a feature of bus rapid transit within the framework of TOD’s principle of developing built environment and transit systems that trigger its citizens to shift from using private motorised vehicle to using transit system for daily mobility. This article explores Transjakarta BRT’s ability to trigger mode shift from doing other way of travelling to using Transjakarta. This article was written through a descriptive-qualitative research using inductive reasoning. Mode shift data was collected through indirect interview using online questionnaire. Other way of travelling prior to using Transjakarta was asked to Transjakarta passengers. Detailed information regarding the passengers’ background and the type of trips the passengers are doing was also gathered. The data was processed using simple statistical analysis and Bartlett’s test for distribution variance. This article finds that Transjakarta is able to trigger mode shift among its passengers. Furthermore, Transjakarta is even able to trigger mode shift from using private motorised vehicle to using Transjakarta. The ability to trigger mode shift is relatively homogenous across all groups of Transjakarta passengers. This article proposes an alternate approach in evaluating a rapid transit system within the framework of TOD, that is evaluating its ability in triggering mode shift.

Research on experimental machine-tractor aggregates equipped with pneumatic hydraulic planetary clutch at road works
Authors: Nekhoroshev D D , Nekhoroshev D A , Konovalov P V , Popov A Yu
Published: June 2021

The use of modern energy-rich equipment in agricultural production led to the increase in the operating speeds of machine-tractor aggregates (MTA), and, accordingly, to the further increase in dynamic loads in the engine-transmission unit. This also influenced the increase in hook load fluctuations relative to the average value up to 30 … 35%, which led to the occurrence of negative phenomena in the tractor running system interaction with the road. The installation of elastically damping elements in the tractor structure is one of the ways to reduce hook load fluctuations in the tractor transmission during road works [3, 6]. The presence of the elastic element in the tractor structure reduces the transmission shafts stiffness by 5 … 10 times. In this case, dynamic loads in transient modes are reduced by 1.1 … 1.28 times, and with the clutch sharp engagement - by 1.6 times.

Published: June 2021

One of the wheeled tractors use effectiveness essential indicators in agricultural production is the indicator of their traction and grip qualities, due primarily to the interaction of the driving wheels with the rolling surface on different soil backgrounds and the slip coefficient. As the result of the wheel propellers interaction with the soil, the latter one is compacted and intensively destroyed. Uneven soil density increases traction resistance and increases the energy consumption for the machine-tractor unit movement (MTU). The possibility of the most effective reduction of hook load fluctuations corresponding to an intensive increase in slipping is provided by the elastic pneumohydraulic element, which has the ability to regulate optimal parameters in a wide range of elastic properties.

Authors: Novikov A E , Filimonov M I , Khadzhidi A E , Dugin E A
Published: June 2021

One of the main reasons for the increase in the ecological tension of aquatic ecosystems remains the discharge into water bodies of domestic wastewater containing toxic substances and pathogenic microorganisms. This is due to the imperfection of water treatment technologies, including due to wear and tear of utility networks and violations in the technological process, accompanied by salvo emissions. Reducing the anthropogenic load on water bodies is possible by retechnologizing various stages of wastewater treatment. The paper describes the design of a sedimentation tank with aeration elements for clarification of urban wastewater, providing an increase in the efficiency of sedimentation of suspended solids. Spraying fine air bubbles contributes to the collision and enlargement of aggregate-unstable elements without the use of coagulants and flocculants. The paper presents a mathematical algorithm for calculating the required deposition surface, taking into account the wastewater flow rate, the nominal diameter of the dispersed phase particles and the required degree of purification. Numerical experiments have shown that for a settlement with a population of 100,000 people, a treatment plant with a standard sedimentation tank is required, the area of which is 130 m2. The use of a sedimentation tank with aeration elements in similar conditions allows reducing the required clarification surface to 120.9 m2 without reducing the clarification efficiency. It has been proven that the spraying of finely dispersed air bubbles helps to reduce the required settling area of the sump by 8%.

Authors: Hoseini Seyed Mohammad Javad , Ghayour Hamid , Salemi Golazani Ali , Kasiri Asgarani Masoud , Ebrahimzadeh Iman
Published: June 2021

In this study, the effect of alteration in the direction of forming during the shear spinning of C11000 copper metal on mechanical properties, microstructure, texture, and anisotropy was investigated. Shear spinning causes the grains stretching along the axial direction besides increasing the grain length in the circumferential direction. Strain-path change in the shear spinning specimens has somewhat resulted in finer grains, more grain refinement, and a higher percentage of high-angle boundaries. More change of strain direction in the shear spinning specimens resulted in approximately 9% to 11% reduction in strength, from 1% to 9% decrease in hardness, and increased elongation from 7% to 37% more than in the specimen without path change. Shear spinning specimens in different paths had different orientations and texture intensities. In the specimen without strain-path change, most of the texture is related to {123}〈412〉 orientation and copper texture with {112}〈111〉 orientation. In the shear spinning specimens in other paths, textures with {001}〈100〉, {011}〈011〉, and {211}〈011〉 orientations and brass texture with {110}〈112〉 orientation were strengthened. Due to the change in texture and mechanical properties, the strain-path change in the shear spinning process reduced the anisotropy in the C11000 copper metal.

BACKGROUND

Blood pressure variability (BPV) is associated with adverse events (AEs) independently of hypertension. It has been suggested that calcium channel blockers (CCBs) may reduce BPV, and thus be particularly valuable in hypertensives with high BPV. We sought to investigate how CCB affect BPV progression and whether long-term adverse effects of BPV differ after CCB treatment than after treatment with other antihypertensives.

METHODS

We retrospectively analyzed 25,268 US veterans who had been followed for 3 years without hypertensive therapy, started on a single class of antihypertensive agents (thiazides, CCBs, ACE inhibitors, or beta blockers [BBs]), treated for 6 years, and then followed for 3 additional years. BPV was calculated as SD of systolic or diastolic blood pressures from at least 10 measurements over each 3-year period. A combined AE endpoint included hospitalization, coronary artery bypass grafting, carotid endarterectomy, angioplasty, amputation, arteriovenous fistula creation, and mortality was assessed in years 9–12.

RESULTS

Post-medication high BPV and BB or thiazide use were associated with increased AE risk. Medication type also affected mean post-medication BPV. The effects of medications except for BBs on AE and mortality was independent of the patient BPV.

CONCLUSIONS

The possible deleterious effects of thiazides should be considered within the context of the study population, who were mostly male and received only a single class of hypertensives. While CCB may ameliorate BPV over time, this study does not support choosing CCB over other agents specifically to lessen BPV-associated risk.
Spatio-temporal differences in leaf physiology are associated with fire, not drought, in a clonally integrated shrub

In highly disturbed environments, clonality facilitates plant survival via resprouting after disturbance, resource sharing among interconnected stems and vegetative reproduction. These traits likely contribute to the encroachment of deep-rooted clonal shrubs in tallgrass prairie. Clonal shrubs have access to deep soil water and are typically thought of as relatively insensitive to environmental variability. However, how leaf physiological traits differ among stems within individual clonal shrubs (hereafter ‘intra-clonal’) in response to extreme environmental variation (i.e. drought or fire) is unclear. Accounting for intra-clonal differences among stems in response to disturbance is needed to more accurately parameterize models that predict the effects of shrub encroachment on ecosystem processes. We assessed intra-clonal leaf-level physiology of the most dominant encroaching shrub in Kansas tallgrass prairie, Cornus drummondii, in response to precipitation and fire. We compared leaf gas exchange rates from the periphery to centre within shrub clones during a wet (2015) and extremely dry (2018) year. We also compared leaf physiology between recently burned shrubs (resprouts) with unburned shrubs in 2018. Resprouts had higher gas exchange rates and leaf nitrogen content than unburned shrubs, suggesting increased rates of carbon gain can contribute to recovery after fire. In areas recently burned, resprouts had higher gas exchange rates in the centre of the shrub than the periphery. In unburned areas, leaf physiology remained constant across the growing season within clonal shrubs (2015 and 2018). Results suggest single measurements within a shrub are likely sufficient to parameterize models to understand the effects of shrub encroachment on ecosystem carbon and water cycles, but model parameterization may require additional complexity in the context of fire.

Drug–target interaction prediction is important for drug development and drug repurposing. Many computational methods have been proposed for drug–target interaction prediction due to their potential to the time and cost reduction. In this review, we introduce the molecular docking and machine learning-based methods, which have been widely applied to drug–target interaction prediction. Particularly, machine learning-based methods are divided into different types according to the data processing form and task type. For each type of method, we provide a specific description and propose some solutions to improve its capability. The knowledge of heterogeneous network and learning to rank are also summarized in this review. As far as we know, this is the first comprehensive review that summarizes the knowledge of heterogeneous network and learning to rank in the drug–target interaction prediction. Moreover, we propose three aspects that can be explored in depth for future research.

Background

No well validated and contemporaneous tools for personalized prognostication of gastric adenocarcinoma exist. This study aimed to derive and validate a prognostic model for overall survival after surgery for gastric adenocarcinoma using a large national dataset.

Methods

National audit data from England and Wales were used to identify patients who underwent a potentially curative gastrectomy for adenocarcinoma of the stomach. A total of 2931 patients were included and 29 clinical and pathological variables were considered for their impact on survival. A non-linear random survival forest methodology was then trained and validated internally using bootstrapping with calibration and discrimination (time-dependent area under the receiver operator curve (tAUC)) assessed.

Results

The median survival of the cohort was 69 months, with a 5-year survival of 53.2 per cent. Ten variables were found to influence survival significantly and were included in the final model, with the most important being lymph node positivity, pT stage and achieving an R0 resection. Patient characteristics including ASA grade and age were also influential. On validation the model achieved excellent performance with a 5-year tAUC of 0.80 (95 per cent c.i. 0.78 to 0.82) and good agreement between observed and predicted survival probabilities. A wide spread of predictions for 3-year (14.8–98.3 (i.q.r. 43.2–84.4) per cent) and 5-year (9.4–96.1 (i.q.r. 31.7–73.8) per cent) survival were seen.

Conclusions

A prognostic model for survival after a potentially curative resection for gastric adenocarcinoma was derived and exhibited excellent discrimination and calibration of predictions.
(De/Re)Constructing LGBT Characters in Latin America: The Implications of Mexican Dubbing for Translating Marginalized Identities
Authors: Bernabo Laurena
Published: June 2021

This article responds to calls for more detailed analyses of localization around the world (E. Castelló, 2009; E. Levine, 2009; S. Waisbord & S. Jalfin, 2009) by examining a Mexican dubbing company and its translation of lesbian, gay, bisexual, and transgender (LGBT) characters for Latin American audiences. Gay, lesbian, and transgender characters’ identities are alternately maintained and mitigated because of industrial norms and technical constraints. While LGBT content has been censored in other national contexts, the current study demonstrates the confluence of factors that result in non-censorial manipulation of these marginalized identities in Latin America. This grounded analysis pulls from ethnographic research at the Mexican dubbing studio New Art Dub and discusses dubbing in terms of industrial practices and decision-making processes to articulate the ways local and global elements intersect. Dubbing professionals offer a point of entry to understand localization dynamics by highlighting to role of cultural mediators whose decisions can reinforce or challenge cultural expectations of LGBT people.
