Authors: Sutrisno Eko , Nurhayati Anis , Apriyanto Mulono
Published: August 2024

Robusta coffee in the Rejosari Mojokerto Village is undertaken by the local community. However, to ensure the production of high-quality coffee and avoid the production of low-priced products, it is imperative for the community to possess a comprehensive understanding and knowledge of coffee post-harvest processing methods. This study aims to investigate the physicochemical properties of Robusta coffee under varying roasting temperatures and times. Several key variables were observed, including the number of beans per 100 grams of coffee, geometric diameter (GM), and average weight of coffee beans, which were employed to assess the physical properties of the coffee. Furthermore, the chemical composition of coffee was analyzed in terms of extract weight, ash content, caffeine, glucose, and coffee protein levels. The results indicate that 100 grams of Robusta coffee contain an average of 368 individual coffee beans, each weighing approximately 0.27 grams, with a geometric dimension (GM) of 10.3 mm. Moreover, the extract weight, caffeine, glucose, and protein content exhibit a decreasing trend during the roasting process. As the roasting time increases and the temperature rises, the percentage of coffee extract and caffeine content decreases. Notably, coffee roasted at 200°C for 20 minutes exhibits the highest ash percentage, reaching 4.16%. It was observed that higher roasting temperatures and longer roasting periods result in increased ash content. This study highlights the significant influence of varying roasting temperatures and times on the quality of the resulting coffee beverage.

Published: August 2024

There are several types of environmental pollution in rural areas in Glagah Subdistrict, Lamongan Regency, such as water, soil, and air pollution. Air pollution occurs because the Glagah Subdistrict is crossed by the inter-regency axis road, which is travelled by many vehicles. Meanwhile, water and soil pollution in this area occur due to fish farming and ponds. In addition, Glagah Subdistrict in Lamongan Regency is considered a flood-prone area due to high rainfall that causes the overflow of Bengawan Solo River. This study aims to determine the quality of the rural environment in Glagah Subdistrict. This study used survey and questionnaire methods. Data were analyzed quantitatively using statistical calculations and frequency tables supported by descriptive analysis. The research parameters observed were environmental quality, disaster-prone potential, and the existence of disaster response by the local village government. The results of this study show that villages in Glagah Subdistrict do not experience air or soil pollution, as they are located far from industrial areas. Instead, water pollution occurs every year, characterized by the proliferation of water hyacinth that covers the surface of the rivers, thus inhibiting the flow of river water. Potential disasters in Glagah Subdistrict are flooding and tornado. Flooding occurs in seven villages located near Bengawan Jero (a tributary of Bengawan Solo) and can be categorized as annual flooding. Villages that are annually affected by flooding do not have disaster mitigation plans, even though funds for such activities are available. Therefore, cross-sectoral cooperation is needed to overcome the annual flooding in Glagah Subdistrict.

Authors: S. Pushpavathi S , Ranjani Sri , Basapur Shravani
Published: August 2024

This study introduces an innovative approach to degrade hazardous dyes by leveraging eco-friendly nano photocatalysts and microbial consortia. The research assesses the effectiveness of this integrated system in dye degradation for wastewater treatment and environmental remediation. Utilizing a bacterial consortium isolated from drains in the textile dyeing industry, alongside a photocatalytic process (Metal oxide/UV), the study demonstrates significant results. When applied individually, both biological and photochemical methods displayed limited decolorization efficiency. However, after 5 days under specific conditions (37°C, pH 7, and 200 mg/L dye concentration), bacterial degradation achieved a noteworthy 72.38% decolorization rate. In comparison, UV photocatalytic treatment with zinc oxide nanoparticles alone yielded a modest 23.5% decolorization. The combined approach, integrating UV-metal oxide treatment with bacterial consortia, showcased the most promising outcome. Notably, the highest bacterial degradation rate of 83.8% was observed when the dye mix sample underwent pretreatment with zinc oxide nanoparticles synthesized using leaves of Parmentiera cereifera, followed by 77.46% with Hibiscus schizopetalus, and 73.9% with Combretum rotundifolium. These previously unexplored plants exhibit potential as sources for green-synthesized metal oxide nanoparticles for dye degradation applications. Further optimization of degradation parameters could unlock the full potential of these nanoparticles.
Spatial and Temporal Synergy: Advanced Autoregression Models for Global Agricultural Development Insights
Authors: Cheung Chris
Published: August 2024

Accurate crop production predictions are crucial for global food security and effective agricultural policymaking. Traditional predictive models often struggle to capture the complex spatiotemporal dynamics qualities in agricultural data. This research aims to improve crop production index predictions by integrating temporal agricultural data from 1990 to 2021 with geospatial information for 162 countries. Advanced time-related architectures, including autoregression (AR), vector autoregression (VAR), spatial temporal autoregressive (STAR), and spatial temporal vector autoregressive (STVAR) models are explored to address the limitations of traditional methods. The study also uses geospatial data to improve the spatial influences inside the models. By combining temporal data (number of years) with geospatial coordinates (longitude and latitude), the research develops predictive models that could better capture the underlying patterns affecting crop production. Various model training measurements are applied to optimize model performance. The outcomes demonstrated that incorporating temporal with spatial data significantly increases the precision of crop yield forecasts as compared to conventional models. The research highlights how the inclusion of both temporal and spatial variables in agricultural predictive modeling can provide useful information for policy makers, farmers and the rest of the actors in agriculture. By creating a platform for using advanced autoregression models and spatiotemporal data integration, it would help improve decision making in agriculture as well as resource management.

Treatment Approaches For Amyotrophic Lateral Sclerosis: Conventional Therapies And Innovative Solutions
Authors: Iyer Srishti , Ho Lananh
Published: August 2024

Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease that impairs motor neuron function, causing progressive muscle weakness and paralysis. ALS is extremely rare, affecting only around 30,000 people in the United States. However, it has a very low survival rate; only 10% of patients survive 10 years after disease onset. While the cause is typically unknown, 5-10% of ALS cases are caused by genetic mutations in the SOD1 and C9orf72 genes. Currently, several FDA-approved therapies for ALS exist. These drugs aim to partially correct the SOD1 mutation, or block cellular and neurological pathways related to motor neuron damage. In clinical studies to date, these drugs either unsuccessfully treat ALS, or are only able to prolong a patient's lifespan up to several months. Scientists are exploring novel therapies that target the root cause of ALS, whether it be damaged neurons, genetic factors, or muscle dysfunction. These therapies include gene therapy, monoclonal antibody therapy, and stem cell therapy. While further research is needed, current data show significant promise, as these treatments directly target the underlying mechanisms of ALS, rather than focusing on select symptoms like conventional approaches, ultimately making new approaches to ALS therapy more sustainable for the future. This paper will discuss and evaluate current FDA-approved therapies for ALS and explore the potential efficacy of novel treatments.

Authors:   Department of Vascular Surgery, Faculty of Medicine, Sana’a University, Sana’a City, Yemen, Y Almadwahi Nabeel , Z Al-Hodiafy Hamza
Published: August 2024

Introduction: The objectives of this study were to ascertain the results of early care and to pinpoint the risk variables linked to death and limb loss in cases of penetrating femoropopliteal vascular damage sustained during Yemeni warfare. Methods: From January 2020 to October 2023, a prospective study was carried out in the military referral center, 48 Model Hospital, located in Sana’a, Yemen. Patients with penetrating femoropopliteal vascular damage from trauma due to combat were the subject of this investigation. Excluded patients were those with primary traumatic amputation, acute trauma, and out-of-hospital treatment. During the preoperative phase and hospital stay, the study used a standardized questionnaire to gather information on patient demographics, damage patterns, surgical repair techniques, and early management outcomes. Results: We analyzed 65 cases of wartime femoropopliteal injuries and found that high-velocity gunshot wounds were the main cause (47.7%). Most patients were young males, with a median age of 25. Associated soft tissue injuries were present in 92.3% of cases, with severe crush injuries in 46.7%. Arterial injuries occurred in 90.8% of patients, predominantly affecting the popliteal artery (57.6%), while venous injuries occurred in 73.8% of patients, mostly involving partial transection of the popliteal vein. Nerve injuries were observed in 13.8% of cases and bone injuries in 21.5%. The primary arterial repair methods were reverse saphenous interposition graft (n=35) and primary reconstruction (n=18), whereas venorrhaphy and saphenous interposition graft were the most common venous repair methods. Intraoperative complications were seen in 7.7% of cases, and postoperative complications in 35.4%, with wound infection being the most frequent. The median hospital stay was 17 days, and secondary amputations were required in 4.6% of cases. The mortality rate was 3.4%. Limb salvage was achieved in 62 patients, with the majority (80%) achieving functional independence in ambulation. Predictors of secondary amputation included intraoperative complications, associated bone fracture injury, systolic blood pressure, hemodynamic instability, intraoperative ankle stiffness, and pulse rate. Predictors of mortality included systolic blood pressure, hemodynamic instability, postoperative ischemia-reperfusion injury, venous ligation, multiorgan failure, sepsis, and septic shock. Conclusion: It is difficult to penetrate femoropopliteal vascular damage in Yemen during hostilities. We stress the significance of shock, ankle rigidity, and IRI as critical risk factors for amputation and mortality, and we recommend for tailored treatment based on hemodynamic stability and muscle viability rather than ischemia duration alone.

Published: August 2024

This article is a review of the academic productions about Social Enterprise (SE) through bibliometric indicators, such as most cited articles and authors, number of publications, institutions, countries, and keywords, to shed light on the concept of SE and find new research lines. The 50 most cited articles were structured into 4 categories: I) entrepreneurship, II) innovation, III) organization, and IV) impact measurement.
Objective: The bibliometric review aims to clarify the concept of SE in the literature through a variety of definitions, and to find new lines of research on the concept.
Methodology: The database of 3,113 publications between 2013-2023 was retrieved from Web of Science (WoS) and analyzed with the software VOSviewer.
Results: The analysis identified four research lines of SE, which allow the observation of the multidimensionality of the SE concept and that point to new research lines.
Limitations: Given its importance in the scholar world, Web of Science is the main source of information in this paper, besides Google Scholar. Further and in greater depth analysis of the SE concept is required using other databases such as Scopus. The same applies to the results of clustering.
Practical implications: The findings can reveal some useful knowledge and skills that universities and business schools, as innovation drivers, should transfer to social entrepreneurs as leaders of an SE.

Owing to the large losses in the conversion process of traditional polarization converters, there is an increasing demand for metasurfaces with excellent transmission performance. In this work, an efficient polarization conversion metasurface is proposed based on electromagnetically induced transparency-like (EIT-like) effect in the terahertz band. The multi-level bright mode paths are excited by an asymmetric structure to obtain orthogonal circular polarization conversion windows. The transmission window is generated by the mutual interference of two sets of bright modes with similar resonant frequencies. Then an asymmetric structure is constructed to achieve transmission window shift under TE polarization and TM polarization, thereby realizing dual-frequency polarization conversion. The metamaterial unit structure consists of four open metal resonant rings and four metal resonant strips. The working mechanism is explored by analyzing the surface current distribution, frequency response, and incident angle characteristics. The results show that electromagnetically induced transparency can be achieved under different polarizations. Furthermore, based on the EIT resonance between the two incident polarizations, the conversion from linear polarization to right-hand circular polarization is achieved at 0.692 THz, and the conversion from linear polarization to left-hand circular polarization is realized at 0.782 THz, transmission coefficients are 0.7 and 0.68 respectively. According to the Stokes parameters, the corresponding ellipticity η values are 96% and 98%, respectively. This EIT-based polarization conversion metasurface with low loss and ultra-thin characteristics has great potential applications in compact antennas, derived radar phased arrays, and military detectors.

The pre-Bötzinger complex is a crucial region for generating respiratory rhythms in mammals. Peripheral chemoreceptors have a significant influence on respiratory rhythm by monitoring changes in blood oxygen concentration and carbon dioxide concentration. This study introduces a closed-loop respiratory control model, which is driven by electromagnetic induction and based on the activation of pre-Bötzinger complex neurons. The model incorporates various factors including the motor pool, lung volume, lung oxygen, blood oxygen, and chemoreceptors. The response of the system subjected to the same hypoxic perturbation under different electromagnetic induction is studied, and the control effect of magnetic flux feedback coefficient on the recovery of mixed rhythms is investigated. Using bifurcation analysis and numerical simulations, it is found that the magnetic flux feedback coefficient has a significant influence on the ability to recover respiratory rhythm. The dynamic mechanism of the magnetic flux feedback coefficient on different hypoxic responses in closed-loop systems are revealed. Dynamic analysis indicates that under certain electromagnetic induction, the mixed bursting rhythm in the closed-loop system can autoresuscitate if the bifurcation structure before and after applying hypoxia perturbation are completely identical. However, when the bifurcation structure before and after applying hypoxia perturbation are different, the mixed bursting rhythm in the system cannot autoresuscitate. In addition, for the cases where automatic recovery is not achieved under mild electromagnetic induction, increasing the magnetic flux feedback coefficient appropriately can lead the system to autoresuscitate, which is closely related to the Hopf bifurcation and fold bifurcation of limit cycle. This study contributes to understanding the influence of the interaction between the central respiratory and peripheral chemoreceptive feedback on respiratory rhythm, as well as the control effect of external induction on the hypoxic response.

Peripheral sensory neurons regenerate their axons after injury to regain function, but this ability declines with age. The mechanisms behind this decline are not fully understood. While excessive production of endothelin 1 (ET-1), a potent vasoconstrictor, is linked to many diseases that increase with age, the role of ET-1 and its receptors in axon regeneration is unknown. Using a single cell RNAseq approach, we reveal that in dorsal root ganglia (DRG), satellite glial cells (SGCs), which completely envelop the sensory neuron soma, express the endothelin B receptor (ETBR), while ET-1 is expressed by endothelial cells. Inhibition of ETBR
ex-vivo
in DRG explant cultures improves axon growth in both adult and aged conditions
. In vivo,
treatment with the FDA- approved compound, Bosentan, improves axon regeneration and reverses the age-dependent decrease in axonal regenerative capacity. Bosentan treatment also enhances the expression of connexin 43 in SGCs after injury in adult and aged mice. These results reveal that inhibiting ETBR function enhances axon regeneration and rescues the age-dependent decrease in axonal regenerative capacity, providing a potential avenue for future therapies.

Transient Receptor Potential Mucolipin 1 (TRPML1) is a lysosomal cation channel whose loss-of-function mutations directly cause the lysosomal storage disorder mucolipidosis type IV (MLIV). TRPML1 can be allosterically regulated by various ligands including natural lipids and small synthetic molecules and the channel undergoes a global movement propagated from ligand-induced local conformational changes upon activation. In this study, we identified a functionally critical residue, Tyr404, at the C-terminus of the S4 helix, whose mutations to tryptophan and alanine yield gain- and loss-of-function channels, respectively. These allosteric mutations mimic the ligand activation or inhibition of the TRPML1 channel without interfering with ligand binding and both mutant channels are susceptible to agonist or antagonist modulation, making them better targets for screening potent TRPML1 activators and inhibitors. We also determined the high-resolution structure of TRPML1 in complex with the PI(4,5)P2 inhibitor, revealing the structural basis underlying this lipid inhibition. In addition, an endogenous phospholipid likely from sphingomyelin is identified in the PI(4,5)P2-bound TRPML1 structure at the same hotspot for agonists and antagonists, providing a plausible structural explanation for the inhibitory effect of sphingomyelin on agonist activation.

MYC family oncoproteins regulate the expression of a large number of genes and broadly stimulate elongation by RNA polymerase II (RNAPII). While the factors that control the chromatin association of MYC proteins are well understood, much less is known about how interacting proteins mediate MYC’s effects on transcription. Here, we show that TFIIIC, an architectural protein complex that controls the three-dimensional chromatin organisation at its target sites, binds directly to the amino-terminal transcriptional regulatory domain of MYCN. Surprisingly, TFIIIC has no discernible role in MYCN-dependent gene expression and transcription elongation. Instead, MYCN and TFIIIC preferentially bind to promoters with paused RNAPII and globally limit the accumulation of non-phosphorylated RNAPII at promoters. Consistent with its ubiquitous role in transcription, MYCN broadly participates in hubs of active promoters. Depletion of TFIIIC further increases MYCN localisation to these hubs. This increase correlates with a failure of the nuclear exosome and BRCA1, both of which are involved in nascent RNA degradation, to localise to active promoters. Our data suggest that MYCN and TFIIIC exert an censoring function in early transcription that limits promoter accumulation of inactive RNAPII and facilitates promoter-proximal degradation of nascent RNA.
