Analysis of Development Patterns of Built Land and Spatial Structure in Bandung City Using Landsat 8 Image Data

The development of an urban area and the increasing totally of population growth greatly affect the need for land. To satisfy these needs, the land changes into built land which causes the density of an area. This study aims to analyze the development pattern of built land and the spatial structure of Bandung City. The data used are the 2015-2020 Landsat 8 time series imagery, the 2019 SPOT-6 imagery, and the administrative boundary map. The analytical methods used to identify and differentiate between built and non-built land classes are NDVI (Normalized Difference Vegetation Index) and the OTSU method with a threshold of 0.1. Based on the analysis, the results obtained are that the changes in the area of built and non-built land in 2015 amounted to 7,115.9 Ha and in 2017 it was 5,977.3 Ha and for 2 years the area decreased by 4%. Meanwhile, in 2017-2019 there was an increase of 2%, and in 2020 it decreased by 2% again. Based on the results of the analysis, the development pattern of land developed in the city of Bandung generally spreads from the city center to the suburbs, which are used as service / government centers, trade and service areas, and infrastructure. With this spreading pattern, the spatial structure is in the form of multiple nuclei or evenly distributed throughout the city of Bandung, where the City Center or CBD is used as a landmark for the surrounding areas. The high development pattern of built land has an impact on the surrounding environment, especially residential areas that have high building density causing the settlement area to become slum and reduce water catchment areas. The conclusion of this study is that the changes in the built-in land from 2015-2020 decreased by 3%, with the development pattern of the constructed land spreading out following the form of the road network, both arterial, collector and local roads.

Phosphorus Requirements of Mungbean (Vigna radiata L.) Wilczek in Selected Soils of South Eastern Nigeria using Sorption Isotherms

The phosphorus requirements of Mungbean (Vigna radiate) in soils derived from Ikom, basalt (BS), Akamkpa, basement complex (BC) and Umudike, Coastal Plain sands (CPS) in South-Eastern Nigeria were estimated using the P- Sorption Isotherms. Soil samples were collected at 0-15 cm depth and the processed method used involved equilibrating 3 g of soil in 30 ml of 0.01m CaCl2 containing 0,5,10,20 and 25 μgg -1 P at room temperature for 5 days. From the P sorption curves, the standard P requirement for the three soils was calibrated and phosphorus requirement of the soils for optimum growth and yield of Mungbean were found to be very low. Different phosphorus levels were calibrated from the sorption isotherm curves and used in fertilizing mungbean in a split-plot potted experiment in completely randomized design (CRD) with three replications. The soil types occupied the main plots while the P levels were assigned to the subplots. A significant response of the mungbean to the applied phosphorus in terms of modulation and grain yield at 5% probability level was observed. Solution concentration of 0.4 μgg -1 in Ikom gave the best nodulation, while Umudike gave the optimum grain yield. The mungbean performed best in Ikom with yield of 9.16 g per plant and least in Akamkpa with a yield of 0.53 g per plant. The use of P- isotherm technique for P fertilizer determination is therefore recommended for efficient P fertilization practice in soils of Southern Eastern Nigeria.
Retrospective Analysis of Patients with Isolated Hand Injuries Admitted to the Emergency Department

Background: Hand and wrist injuries account for approximately 10% of all emergency department admissions. Hand traumas, especially hand fractures, are associated with social deprivation except in very young and very old individuals. In this study, we aimed to evaluate the clinical characteristics, risk factors, and the effect of injury on the life of patients admitted to the emergency department for an isolated hand injury. Materials and Methods: Patients who were admitted to the emergency department due to an isolated hand injury between 1 November 2019 and 1 November 2020 were included in the study. Multivariate logistic regression analysis was used to determine the risk factors of permanent disability. Results: The study included 205 patients with a mean age of 28.05 ± 10.85 years, and 142 (69.3%) of them were male. The vast majority of patients (n = 149; 72.7%) were in the 18–35 years age group. The mechanism of injury was blunt trauma in 131 (63.9%) patients and penetrating trauma in 65 (31.7%) patients. Amputation was necessary in 25 (12.2%) patients, and 20 (9.8%) patients had a permanent disability. Results of the logistic regression analysis revealed that male sex and penetrating trauma were independent risk factors for permanent disability (p = 0.012 and p < 0.001, respectively). Conclusions: Evaluation of hand injuries and related factors in our region is important because the results can vary between regions due to differences in lifestyle and working conditions. We found that male sex and penetrating trauma are independent risk factors for permanent disability in patients with isolated hand injury. Preventive measures against such injuries could reduce the permanent disability and related mental and economic burden.
Conducting Polymer‐Based Granular Hydrogels for Injectable 3D Cell Scaffolds

Injectable 3D cell scaffolds possessing both electrical conductivity and native tissue‐level softness would provide a platform to leverage electric fields to manipulate stem cell behavior. Granular hydrogels, which combine jamming‐induced elasticity with repeatable injectability, are versatile materials to easily encapsulate cells to form injectable 3D niches. In this work, it is demonstrated that electrically conductive granular hydrogels can be fabricated via a simple method involving fragmentation of a bulk hydrogel made from the conducting polymer PEDOT:PSS. These granular conductors exhibit excellent shear‐thinning and self‐healing behavior, as well as record‐high electrical conductivity for an injectable 3D scaffold material (≈10 S m−1). Their granular microstructure also enables them to easily encapsulate induced pluripotent stem cell (iPSC)‐derived neural progenitor cells, which are viable for at least 5 d within the injectable gel matrices. Finally, gel biocompatibility is demonstrated with minimal observed inflammatory response when injected into a rodent brain.
Target tracking algorithms for multi-UAVs formation cooperative detection*

This paper considers the problem of the ground target positioning and tracking algorithm for multi UAVs formation cooperative detection, and a real time and fast algorithm is proposed based on UAV airborne electro optical sensors. One state estimation problem for nonlinear stochastic system is studied by means of the unscented Kalman filter algorithm from target tracking process. To extend the single target tracking to multiple target tracking, one improved unscented Kalman filter algorithm is advised based on iterative multiple models. Furthermore, to relax the strict condition on white noise in Kalman filtering, the target tracking or state estimation is reduced to derive the inner and outer ellipsoidal approximations for the state in case of unknown but bounded noise. Finally, one simulation example confirms our theoretical results.
The effects of exercise training on vascular function among overweight adults with obstructive sleep apnea

Obstructive sleep apnea (OSA) is associated with increased cardiovascular morbidity due, in part, to impaired vascular function. Exercise confers cardioprotection by improving vascular health. Yet, whether OSA severity affects the vascular improvements conferred with exercise training is not known. Overweight (body mass index (BMI) >27 kg/m2) adults were evaluated for OSA and enrolled in a 6‐week exercise intervention. Baseline assessments of brachial artery flow‐mediated dilation (BAFMD), central augmentation index (AIx), and pulse wave velocity (PWV) were repeated post‐training. Fifty‐one participants (25 men; 26 women) completed the study. Despite improved aerobic capacity (P = .0005) and total fat mass (P = .0005), no change in vascular function was observed. Participants were divided into two severity groups according to their baseline total apnea‐hypopnea index (AHI) as either 5 to 14.9 events per hour (n = 21; Age = 48 ± 7 years; BMI = 33.7 ± 4.6 kg•m−2) or ≥15 events per hour (n = 30; Age = 56 ± 13 years; BMI = 34.3 ± 4.2 kg•m−2). No effect of OSA group was observed for BAFMD (P = .82), AIx (P = .37) or PWV (P = .44), suggesting that OSA severity does not influence the effect of exercise on vascular function. The vascular effects of extended exercise programs of greater intensity in overweight OSA patients should be examined.
A performance predictor for implementation selection of parallelized static and temporal graph algorithms

Task‐based execution of graph workloads allows various ordered and unordered implementations, with tasks representing dependencies between graph vertices and edges. This work explores graph algorithms in the context of ordered and unordered task‐based implementations, that trade‐off work‐efficiency with parallelism. The monotonicity of convergent graph solutions is the reason behind the trade‐off between work‐efficiency and parallelism. This trade‐off results in variable performance‐based choices within and across different machines (CPUs and GPUs), graph algorithms, implementations (ordered, relaxed, and unordered). Input graphs also augment this choice space, with this work analyzing temporally changing graphs in addition to the static graphs explored by prior works. These algorithmic and architectural choices are first explored in this work, and it is seen that different graph workload‐input combinations perform optimally on diverse architectural configurations. The resulting choice space is analyzed and this work represents it in the form of characteristic variables that correlate with each choice space. Using these characteristic variables, this work proposes analytical and neural network models to correlate these choice spaces to find the best performing implementation. The variables and the prediction models proposed in this work are also integrated with a state‐of‐the‐art performance predictor on a multiaccelerator setup, and shows geometric performance gains of 54% on a CPU, 14% on a GPU, and 31.5% in a multiaccelerator setup over baseline implementations without performance prediction.
Degradation of Three Acetanilide Herbicides in Soil

The persistence of alachlor [2-chloro-2′,6′-diethyl-N-(methoxymethyl) acetanilide], metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide], and propachlor (2-chloro-N-isopropylacetanilide) in soil was examined under laboratory and field conditions using sorghum (Sorghum vulgare Pers. ‘NB280S′) or annual ryegrass (Lolium multiflorum Lam.) as bioassay species. In laboratory studies, degradation rate of alachlor and propachlor was greater at 50 and 80% than at 20% field capacity at 20 C. Degradation of metolachlor was greater at 80 than at 20% field capacity. Degradation rate of alachlor and metolachlor at 50% field capacity was greater at higher temperatures. Propachlor degradation rate varied with temperature. Under irrigated, cropped field conditions, the order of persistence was metolachlor > alachlor > > propachlor.
Selection of industrial and organisational psychology master’s students: Exploring the predictive validity of a person–job fit approach

Orientation: Valid selection of master’s students is essential to the training and development of competent Industrial and Organisational Psychologists. Research purpose: To validate a person-job fit data aggregation approach based on an integration of psychometric results in the selection of Industrial and Organisational Psychology master’s students. Motivation for the study: The Employment Equity Act requires psychological assessment to be valid, reliable, culturally fair and based on the inherent requirements of the job. This mandates context-specific validation research, such as the current study. Research approach/design and method: A non-experimental design was applied to secondary data ( N = 133) derived from the Occupational Personality Questionnaire, Verify Ability Tests and academic success results of 5 student cohorts registered in the years 2012 to 2016. Data was analysed by means of descriptive and correlation statistics. Main findings: The overall Person Job Match score did not show a statistically significant relationship with academic success. A significant relationship was observed between cognitive ability and academic success. Specific Person Job Match competencies presenting a significant relationship with academic success, contained scores from both personality and cognitive measures. Practical implication: Ability tests should be weighted more strongly in selecting master’s students. A review of the master’s students’ competency profile may be needed to align with future world of work demands, and to improve its predictive role in academic success. Contribution/value added: This study contributes to the predictive validity of the selection criteria for Industrial and Organisational Psychology master’s students.
Seasonal variation in atmospheric pollutants transport in central Chile: dynamics and consequences

Abstract. Central Chile faces atmospheric pollution issues all year long as a result of elevated concentrations of fine particulate matter during the cold months and tropospheric ozone during the warm season. In addition to public health issues, environmental problems regarding vegetation growth and water supply, as well as meteorological feedback, are at stake. Sharp spatial gradients in regional emissions, along with a complex geographical situation, make for variable and heterogeneous dynamics in the localization and long-range transport of pollutants, with seasonal differences. Based on chemistry–transport modeling with Weather Research Forecasting (WRF)–CHIMERE, this work studies the following for one winter period and one summer period: (i) the contribution of emissions from the city of Santiago to air pollution in central Chile, and (ii) the reciprocal contribution of regional pollutants transported into the Santiago basin. The underlying 3-dimensional advection patterns are investigated. We find that, on average for the winter period, 5 to 10 µg m−3 of fine particulate matter in Santiago come from regional transport, corresponding to between 13 % and 15 % of average concentrations. In turn, emissions from Santiago contribute between 5 % and 10 % of fine particulate matter pollution as far as 500 km to the north and 500 km to the south. Wintertime transport occurs mostly close to the surface. In summertime, exported precursors from Santiago, in combination with mountain–valley circulation dynamics, are found to account for most of the ozone formation in the adjacent Andes cordillera and to create a persistent plume of ozone of more than 50 ppb (parts per billion), extending along 80 km horizontally and 1.5 km vertically, and located slightly north of Santiago, several hundred meters above the ground. This work constitutes the first description of the mechanism underlying the latter phenomenon. Emissions of precursors from the capital city also affect daily maxima of surface ozone hundreds of kilometers away. In parallel, cutting emissions of precursors in the Santiago basin results in an increase in surface ozone mixing ratios in its western area.
Teneurs en phénols totaux, activités antioxydantes des macérés et décocté des feuilles de Uvaria chamae P. Beauv. (Annonaceae)

Uvaria chamae is a plant of the Ivorian biodiversity used in traditional medicine. Despite the biological and therapeutic virtues of this plant, little information on the total phenol content and antioxidant activity exist. The objective of this study was to evaluate the total phenol content, antioxidant activity of aqueous macerate, B. BAMBA et al. / Int. J. Biol. Chem. Sci. 15(1): 54-67, 2021 55 ethanolic macerate and aqueous decocate of Uvaria chamae leaves. The total phenol content was determined by the Folin-Ciocalteu method. Antioxidant activity was evaluated by the DPPH (2,2-diphenyl-1-picrylhydrazyl) and ORAC (Oxygen Radical Absorbance Capacity) scavenging method. The total phenol content was 110.51 ± 7.18 μg GAE/mg extract, 86.34 ± 1.38 μg GAE/mg extract and 65.80 ± 0.13 μg GAE/mg extract for ethanolic macerate, aqueous decocate and aqueous macerate of Uvaria chamae, respectively. The different macerated and decocted products presented an activity of scavenging of the two free radicals. Concerning the DPPH radical, the ethanolic macerate of U. chamae exerts a significant antiradical activity with an IC50 of the order of 0.08 ± 0.02 mg/ml. With the ORAC method, the ethanolic macerate of U. chamae (3.51 ± 0.15 μmol TE/μg extract) and the aqueous decocate of U. chamae (3.36 ± 0.18 μmol TE/μg extract) show significant antioxidant activity values. On the other hand, the antioxidant activity values of the aqueous macerate of U. chamae (3.04 ± 0.20 μmol TE/μg extract) and the positive control: ethanolic extract of R. officinalis (2.54 ± 0.06 μmol TE/μg extract) are not significantly different (P ˃ 0.05). These results show the existence of a good linear correlation between the total phenol content and the antioxidant power of the different macerated and decocted phenols of this plant. This Ivorian plant could thus be considered as a source of natural antioxidant for medicinal purposes. © 2021 International Formulae Group. All rights reserved.
Brixenbach research catchment: Quantification of runoff process proportions in a small Alpine catchment depending on soil moisture states and precipitation characteristics

The Brixenbach valley is a small Alpine torrent catchment (9.2 km2, 820–1950 m a.s.l., 47.45°, 12.26°) in Tyrol, Austria. Intensive hydrological research in the catchment since more than 12 years, including a hydrogeological survey, pedological and land use mapping, measurements of precipitation, runoff, soil moisture and infiltration as well as the conduction of rainfall simulations, has contributed to understand the hydrological response of the catchment, its subcatchments and specific sites. The paper presents a synthesis of the research in form of runoff process maps for different soil moisture states and precipitation characteristics, derived with the aid of a newly developed Soil‐hydrological model. These maps clearly visualize the differing runoff reaction of different subcatchments. The pasture dominated areas produce high surface flow rates during short precipitation events (1 h, 86 mm) with high rainfall intensity, whilst the forested areas often develop shallow subsurface flow. Dry preconditions lead to a slight reduction of surface flow, long rainfall events (24 h, 170 mm) to a dominance of deep subsurface flow and percolation.

Current treatment approaches for breast cancer patients with HER2-positive disease in the adjuvant, and neo-adjuvant setting

Breast cancer (BC) is the second most common cancer and the leading cause of mortality among women globally. Approximately 20% to 25% of BC patients have amplification of the human epidermal growth factor receptor 2 (HER2) genes, a marker of poor prognosis. However, the introduction of anti-HER2therapies (trastuzumab, followed closely by lapatinib, pertuzumab, and T-DM 1) has changed the natural history of HER2-positive BC and improved the prognosis and survival in HER2-positive BC patients. The approval of trastuzumab and pertuzumab linked with a taxane as a first-line treatment and follow-up treatment with the antibody-drug conjugate T-DM1 has undeniably contributed to attaining these outcomes. The Tyrosine Kinase Inhibitor lapatinib is another commonly used treatment in combination with capecitabine, approved on the basis of an improvement in progression-free survival. The superiority of combination anti-HER2 therapy to achieve more complete inhibition of the various HER receptor dimers has been demonstrated in clinical studies. Nonetheless, studies have also suggested that some HER2-amplified tumors may benefit from anti-HER2 therapy combined with only a single chemotherapy agent or in the absence of any chemotherapy. However, despite therapeutic advances, tumors expressing estrogen receptor (ER) have poorer responses to targeted therapy and are more likely to relapse. A better understanding of resistance to existing anti-HER2 agents, along with the role played by the microenvironment and of interconnected signaling pathways, can permit tailor-made therapeutic options for each patient. The aim of this review is to evaluate treatment approaches for BC patients with HER2-positive disease in the adjuvant, and neoadjuvant setting.
