Drought is a disaster that has a bad impact, especially in the city of Banjarbaru. There are various ways to reduce the impact of drought in the future, one of which is by looking for information regarding the predicted drought index for the following year. The data used in this research to find the drought index value is Banjarbaru City rainfall data for 2007-2022. Seasonal Autoregressive Integrated Moving Average (SARIMA) method is a calculated method for predicting rainfall data and the data obtained is a forecast of rainfall in the city of Banjarbaru for the next 12 periods, namely SARIMA (0,2,3) (0,1,1)12. This model is a model that is suitable for use because it has fulfilled several tests, namely stationarity of variance and mean, significance test, white noise test and normality test with an AIC value of 1022,60 and an equation model obtained from SARIMA (0,2,3) (0,1,1)12 is (1-B)2 (1-B12) Zt=(1+1,77B-0,54B2+ 0,23B3 )(1-0,96B12 )εt. After obtaining forecast rainfall data for the next 12 periods. Rainfall data for 2007-2022 and forecast results for 2023 were used to find the drought index value using the Standardized Precipitation Index (SPI) method. It was found that the highest negative drought index value occurred in January, namely -1,774, including the dry category and the drought index had a positive value The highest occurred in June, namely 0,582, including the normal category. The calculation results of this drought index forecast are used to provide additional information to anticipate drought disasters in the future.

HIV is a virus that infects the immune system cells, thereby damaging the human immune system. AIDS is a collection of symptoms that arise due to the compromised immune system of the human body as a result of a positive infection by the HIV virus. HIV/AIDS remains a complex and significant global health issue. Despite advancements in treatment and prevention, the severity of HIV/AIDS remains a primary focus in healthcare management efforts. This study aims to determine the factors influencing the severity of HIV/AIDS patients at the Regional Hospital of Idaman Banjarbaru using ordinal logistic regression analysis. Ordinal logistic regression is employed to understand the relationship between the dependent variable (severity of the disease) and independent variables, where the dependent variable is ordinal in scale. The data used for this analysis is secondary data extracted from the inpatient medical records of the Idaman Banjarbaru Regional Hospital, comprising a total of 68 cases of HIV/AIDS. Assumed factors influencing the severity of patients include gender, age, duration of hospitalization, education, employment status, marital status, and place of residence. The analysis results indicate a significant relationship between the severity of HIV/AIDS patients and marital status. The highest likelihood of patients experiencing HIV/AIDS is in the divorced response category with a stage 3 category, where the probability value is 0.943. Individuals in the married and divorced categories are 1.53 times more likely to experience HIV/AIDS with a stage 4 status and complications ranging from 3 to 5.

ANALISIS PENGARUH INDUSTRI MIKRO DAN KECIL TERHADAP PERTUMBUHAN EKONOMI DI INDONESIA DENGAN PENDEKATAN EKONOMETRIKA REGRESI SPASIAL DATA PANEL
Authors: Winata Jonathan Adi 
Published: August 2024

AbstractOne indicator to assess the economic condition of a country is Gross Domestic Product (GDP) at the national level or Gross Regional Domestic Product (GRDP) at the regional level. The sector that contributes the most to Indonesia's GDP is the manufacturing industry. One of the most crucial components within the manufacturing sector is the micro and small-scale industry (MSI). The presence of MSIs significantly contributes to economic development, closely tied to the geographical location among regions, thereby exerting spatial influence on the GRDP of a region. Hence, an analysis of GRDP considering spatial aspects is necessary, investigating the impact of the Micro and Small-scale Industry (MSI) sector on economic growth in Indonesia using spatial panel data regression. The spatial models constructed in this study include the Spatial Autoregressive Model (SAR) and Spatial Error Model (SEM) involving fixed-effect influence. This research aims to describe and identify the factors within MSIs that influence economic growth in each province of Indonesia. The results indicate that the appropriate model used is the Spatial Autoregressive Model Fixed Effect (SAR-FE). Overall, there are two independent variables significantly affecting economic growth, namely the number of micro and small-scale industries (X1) and inflation (X6). The results show that an increase in the percentage of these two variables will decrease the economic growth rate.

Published: August 2024

In a context of increasing interest in the production of wine-based beverages with lower ethanol content, the present work explored the role of ethanol in the sensory properties of model wines (MW). Four sets of MWs (red and white) with alcohol contents ranging from 0.5 to 15 % (1st study) and from 12 to 15 % (2nd study), the non-volatile fraction of real wines and fixed aroma compositions were all prepared and characterised by sensory descriptive analysis. The results indicate that sensory effects were stronger in red MWs than in white MWs, and that alcohol levels below 10 % in reds and 7.5 % in whites cause the models to become unbalanced with excessive sourness. In whites, low-alcohol MWs also showed reduced levels of perceived bitterness, and only at high ethanol levels were body and alcoholic aroma more intense. In reds, the low alcohol MWs showed less positive aroma persistence (perceived retronasally) and less body; at 0.5 % ethanol the positive odour intensity (perceived orthonasally) was minimal and at higher ethanol levels, the models became sweeter and more alcoholic. Overall, although samples with similar alcoholic contents maintained some sensory similarity, there were relevant discontinuities caused a slight increase in ethanol (0,5 %) to have a dramatic sensory impact, with some sensory descriptors showing significant maxima or minima at these alcohol levels. In reds, sourness, alcohol and astringency perceptions were maximum at 13.5 % and 15 % and body at 13 % and 15 %; meanwhile, red fruit was minimum at 13 % and 15 %, peaking at 14.5 %. In whites, alcohol perception was also maximum at 13.5 % and 15 %, while sweetness was maximum at 13.5 % and 14.5 %. These results demonstrate that ethanol exerts profound effects on sensory properties, probably due to strong perceptual interactions with odour, taste and tactile properties.

Abstract
Strategy for Increasing Community and Regional Aspiration Proposals in National Development Planning. This study aims to investigate why proposals for community and regional aspirations in national development planning have not been optimal and how the strategy for increasing community and regional aspirations in national development planning can be improved. This research employs a qualitative approach with a descriptive approach. The interactive model Miles, Huberman, and Saldana were used to analyze the data (2014). The research findings indicate that the proposals for community and regional aspirations in national development planning are not yet optimal, among other reasons, because (1) the proposed system for community and regional aspirations is not yet optimally developed following the needs of members and the needs of the community; (2) no regulation regulates as a guideline for processing Community and Regional Aspirations; and (3) the available human resources are insufficient. For this reason, as a result, the Strategy for Enhancing Proposed Community and Regional Aspirations in Regional Development Planning must prioritize synchronization, coordination, and integration with national development planning because regional development goals must support national development goals.

Abstract

The Arctic Ocean (AO) is changing at an unprecedented rate, with ongoing sea ice loss, warming and freshening impacting the extent and duration of primary productivity over summer months. Surface microbial eukaryotes are vulnerable to such changes, but basic knowledge of the spatial variability of surface communities is not well understood. Here, we sampled microbial eukaryotes in surface waters of the Beaufort Sea from four contrasting environments: the Canada Basin (open ocean), the Mackenzie Trough (river-influenced), the Nuvuk region (coastal) and the under-ice system of the Canada Basin. Microbial community structure and composition varied significantly among the systems, with the most phylogenetically diverse communities being found in the more coastal systems. Further analysis of environmental factors showed potential vulnerability to change in the most specialised community, which was found in the samples taken in water immediately beneath the sea ice, and where the community was distinguished by rare species. In the context of ongoing sea ice loss, specialised ice-associated microbial assemblages may transition towards more generalist assemblages, with implications for the eventual loss of biodiversity and associated ecosystem function in the Arctic Ocean.

Published: August 2024

Abstract

In breast cancer, triple negative (TN) breast cancer has most responses to immune checkpoint inhibitor (ICI) therapy. Lymphocyte infiltrate does not impact prognosis in Hormone receptor positive HER2 negative (HR + HER2-) breast tumors and few HR + HER2- tumors respond to ICI. We contrasted immune-associated gene expression between 119 TN and 475 HR + HER2- breast tumors from The Cancer Genome Atlas (TCGA) and confirmed our findings in 299 TN and 1369 HR + HER2- breast tumors in the METABRIC database. TN and HR + HER2- tumors grouped into immune-high or -low tumors, both subtypes were represented in the immune-high group. The largest difference between the immune-high TN and HR + HER2- tumors was TN tumors had more abundant Th1 and Th2 CD4+ T cells while HR + HER2- tumors had more abundant fibroblasts (log2FC > 0.3; p < 10X10− 10). This suggests an immune-high signature is not dictated by breast cancer subtype, but fibroblast subsets associated with worse outcome were higher in the immune-high HR + HER2- tumors.
Risk assessment and source apportionment for PAHs in wetland sediment and biomonitoring by Alternanthera ficoidea (L.) plant
Authors: Dhara Aparna , Dutta Ratna 
Published: August 2024

Abstract

The study focuses on monitoring of PAHs pollution in East Kolkata Wetland, a Ramsar site in India using biomonitoring potential of Alternanthera ficoidea (L.) plant. Root, shoot, leaves and rhizobium of the plant are checked with respect to PAHs accumulation and translocation. Measurement of total concentration of 16 priority PAHs in that wetland sediment (85.37±3.37 µg/g) along with Benzo[a]pyrene equivalent toxicity (21.252±0.96 µg/g) indicates high carcinogenic risk based on Canadian soil quality guidelines. The APTI value of Alternanthera ficoidea (22.25±0.12>17) recognizes it as tolerant species. SEM analysis of leaf sample shows stomatal blockage by particulate matter which implies PAHs storage in it. Different parts of the plant viz root, shoot, leaves and rhizobium show different uptake and distribution pattern of PAHs (∑ PAHsleaf : 420.23±0.60 µg/g, ∑ PAHsstem : 230.83±4.87 µg/g, ∑ PAHsroot 68.45±3.17µg/g and ∑ PAHsrhizobium (68.66±4.35 µg/g). Significance of the results is arbitrated based on one-way ANOVA (p (2.7×10-5<0.5)) and F (7.77) >Fcrit (2.49)). Determination of lipid content of leaf, root and stem reconfirms it as good bioaccumulator of PAHs. The study also highlights the LMW and HMW accumulation pattern in different parts of plants and translocation of PAHs from root is also described in connection. Source apportionment analysis based on some diagnostic ratios suggests that pyrogenic activities (more specifically vehicular emissions) are the potential contributor of PAHs sources in that wetland. Bioconcentration and translocation factors supports distributional pattern of PAHs in different parts of plants and moreover revealed that both air-to-leaf and sediment-to-root transfer pathways are contributor for bioaccumulation.

Published: August 2024

Abstract

This sub-analysis of the ePREDICE trial, investigated the prevalence and determinants of renal complications, specifically glomerular hyperfiltration, albuminuria, and reduced kidney function, in individuals with prediabetes (PD). The cohort consisted of 967 participants from diverse backgrounds across seven countries. The kidney function was evaluated using the MDRD-4 equation, and the influence of various clinical and demographic factors on renal involvement was assessed by multivariable regression models. Additionally, insulinogenic and disposition indices were examined. Overall, the prevalence of renal abnormalities in this PD cohort was 9.2% (n = 89). Key findings included the detection of hyperfiltration in 20 (2%) individuals, albuminuria in 45 (4.7%), and CKD stage G3a in 29 (3%). Hyperfiltration was inversely correlated with age and height, while albuminuria showed a significant direct association with the disposition index (DI). Age and waist circumference were significantly and directly associated with estimated glomerular filtration rate (eGFR). The ePREDICE study highlights critical factors that affect renal involvement in PD individuals, revealing complex interactions among various parameters. These findings further emphasize the necessity for the search of early kidney abnormalities in people with PD especially in those in older age groups and with a large waist circumference.
Coral larvae on demand: a novel method for an instant acquisition of healthy brooded larvae

Published: August 2024

Abstract

Access to coral larvae is crucial for research on early life stages of corals, yet traditional methods for obtaining brooded larvae are labor-intensive and time-consuming. We present a novel method to efficiently collect viable brooded larvae within minutes from colonies of five different scleractinian coral species (Leptastrea purpurea, Leptastrea transversa, Tubastraea faulkneri, Pocillopora acuta, Favia fragum). By immersing the colonies in seawater containing 5–10 g/L potassium chloride for 5–7 minutes, we induced instant larval release. This method yielded a similar quantity of larvae compared to traditional methods. The larvae remained viable, surviving storage for several weeks and settling successfully. Our method is both faster and easier than traditional methods, suitable for application with aquarium-cultured corals or in field stations. The potassium chloride technique was effective for all tested coral species that tolerate elevated potassium ion concentrations without harm. However, it should not be applied to potassium-sensitive corals like Euphyllia. Coral reproduction, larval release, planulation, brooder, spawning, settlement cues

Abstract

Accurate prediction of Particulate Matter (\({PM}_{10}\)) levels, an indicator of natural pollutants such as those resulting from dust storms, is crucial for public health and environmental planning. This study aims to provide accurate forecasts of \({PM}_{10}\) over Morocco for five days. The Analog Ensemble (AnEn) and the Bias Correction (AnEnBc) techniques were employed to post-process \({PM}_{10}\) forecasts produced by the Copernicus Atmosphere Monitoring Service (CAMS) global atmospheric composition forecasts, using CAMS reanalysis data as a reference. The results show substantial prediction improvements: the Root Mean Square Error (RMSE) decreased from 63.83 \(\mu g/{m}^{3}\) in the original forecasts to 44.73 \(\mu g/{m}^{3}\) with AnEn and AnEnBc, while the Mean Absolute Error (MAE) reduced from 36.70 \(\mu g/{m}^{3}\) to 24.30 \(\mu g/{m}^{3}\). Additionally, the coefficient of determination (\({R}^{2}\)) increased more than twofold from 29.11–65.18%, and the Pearson correlation coefficient increased from 0.61 to 0.82. This is the first use of this approach for Morocco and the Middle East and North Africa and has the potential for translation into early and more accurate warnings of \({PM}_{10}\) pollution events. The application of such approaches in environmental policies and public health decision making can minimize air pollution health impacts.

Abstract

This paper reports a process for obtaining superhydrophobic clays from Tagan bentonite to produce anhydrous drilling fluids from superhydrophobic organo-clays. Various cationic surfactants were used as superhydrophobisers. An organophilic (superhydrophobic) clay with a contact angle of 170° was obtained in the presence of tetrakis(decyl)ammonium bromide (TKAB). Placing a water drop on the surface of the resulting superhydrophobic clay powders and measuring the contact angle of the water drop on the powder are challenging because the water drop runs off quickly, similar to a mercury drop. The distribution and stability of organophilic clay particles in diesel fuel fluid obtained by TKAB were determined optically. The organophilic clay particles based on TKAB formed a stable suspension in diesel fuel and did not mix with the water phase. In the water phase, the TKAB-based organophilic clay could remain on the surface of the water phase for more than 365 days. Thermo-gravimetric analysis and differential scanning calorimetry were performed on Tagan clay and organo-clay obtained by TKAB because drilling melts can be subjected to high underground temperatures. A methodology for obtaining drilling fluid was proposed based on these data. The resulting drilling fluid belongs to the type of drilling fluids based on organo-clay in the presence of anhydrous petroleum products with thixotropic properties. This drilling fluid was prepared according to the characteristics of Kumkol oil. The formulation of the resulting anhydrous drilling fluids and their technical characteristics are presented.
