Intensive research on the effectiveness of chemoattractants has been widely explored to improve the feed qualities in expanding crustacean farming. Taste preferences in slipper lobster remained unknown despite their significant contribution to the lobster fisheries. Chemoattractants allow better performance in aquaculture species by increasing food attractiveness and palatability. Amino acids (AA) have been leading in previous research on crustacean feeding behavior. Given that slipper lobster possesses chemoreceptors to detect and orient towards food, this study investigated an approach to identify the AA with the most potent chemoattractant in eliciting a response from slipper lobster. Behavioral assays were performed to evaluate the responses of slipper lobster Thenus orientalis (carapace length, 52.34 ± 1.52 mm) on 15 crystalline AA and three derivatives of AA (DAA) at three concentrations between 10−1 and 10−3 M as test substances (TS). Meretrix sp. extract was used as a positive control and clean filtered seawater as a negative control. The behavioral responses of 14 T. orientalis were evaluated based on their antennular flicking rate, third maxillipeds activity, and substrate probing by the pereiopods. T. orientalis responded to the solutions of single AA down to a concentration of 10−3 M, excluding histidine and serine. The behavioral activity displayed by T. orientalis increased with the TS concentrations. L-glutamic acid monosodium salt monohydrate, betaine, and glycine solutions elicited the most behavioral responses, whereas histidine exhibited the lowest behavioral responses. Conclusively, L-glutamic acid monosodium salt monohydrate, betaine, and glycine can be potential chemoattractants for T. orientalis.

This paper investigates the relationship between a building's past energy consumption and the outdoor temperature and predicts the next day's energy consumption using a refined time series model. Maintaining optimal indoor temperatures relative to outdoor temperatures determines a building's HVAC demand and, thus, energy consumption. We want to determine how outdoor temperature and other factors determine this consumption. With increasing urbanization and energy demand, it is important to understand building energy consumption, especially in terms of its impact on the environment. Previous research has shown the link between electricity consumption and external environmental factors and highlighted energy optimization's importance in urban structures. As cities become large energy consumers, studies point to the need to understand energy use patterns on a regional and temporal scale.
For accurate energy forecasts, data becomes the linchpin. Time series—data points arranged in chronological intervals—are foundational in predictive modeling. Due to buildings' intricate electricity consumption patterns, traditional linear forecasting often falls short. Enter nonlinear regression models: These complex models are apt for mapping and predicting nonlinear data trends. Notwithstanding their advantages, they come with challenges, primarily the high-frequency data influx from smart meters and IoT devices. But their potential benefits - from cost savings to efficient energy management - are significant. In a world caught between urban expansion and ecological preservation, efficient energy management is crucial. Accurate energy forecasting, especially for buildings, combines technological advances, statistical acumen and environmental imperatives. Understanding building energy consumption using sophisticated nonlinear regression models is evolving from an academic goal to a global necessity.
Factors Contributing to the Failure of Women’ssmall-Scaled Enterprises in Dodoma City Council, Tanzania
Authors: Gamba Frank Biseko , Pesha John , Chaula Egidio 
Published: October 2023

Aims: This study presents the findings on the Factors Contributing to the Failure of Female Small-scale Enterprises in Dodoma City Council, Tanzania. The study was guided by three specific objectives: to identify structural factors contributing to the failure of women small-scale entrepreneurs, to find out social factors contributing to the failure of women small-scale entrepreneurs and to examine economic factors contributing to the failure of women small-scale entrepreneurs.
Methodology: The study adopted a cross-sectional research design where structured questionnaire with open and close-ended questions were used to collect primary information from a sample size of 70 respondents. The researcher used a mixed-research approach, that is, qualitative and quantitative. A qualitative approach was used in collecting respondents’ views during the interviews while the quantitative approach was used to collect information from respondents through questionnaires. Quantitative data analysis was done by using Statistical Product for Social Solution (SPSS) computer program version 25.0.
Results: The general findings indicated that government regulations like long license processing and unfavorable tax, scarcity of cash flow at the start-up, and operating and expanding their businesses served as the factors contributing to the failure of women small-scale enterprises in Dodoma City Council. It was further found that high interest rates from banks and other financial institutions affected the growth of enterprises; also, men’s perception that women’s responsibility is to take care of their families instead of working to increase their family income accelerated women to perform business as a part-time activity hence failure in business.
Conclusion: the study recommends that women’s small-scaled entrepreneurs must form groups to work together in cooperatives to reduce the business running costs such as tax, rent payable and interest rates from the financial institutions. In addition, the government should enforce laws to eradicate bureaucracy and corruption based on sex, place of origin, favoritism and infidelity from some government officials and credit officers during the compliance of business tax approximation and loan application processing.
Pharmaco-Invasive Therapy is a Critical Option in Nigerian Stemi Treatment: A Review
Authors: Edafe Emmanuel Auchi , Jumbo Johnbull 
Published: October 2023

Primary percutaneous coronary intervention (PCI) is the recommended reperfusion approach in patients with ST-segment elevation myocardial infarction (STEMI), When conducted in a timely and by skilled operators. This technique, however, has proven to have limitations in areas without PCI facilities and with long wait times between the initial medical contact and balloon because to logistical issues and a lack of skilled operators. In STEMI patients, pre-treatment with a fibrinolytic prior to PCI has the potential to give early pharmacologic reperfusion before definitive PCI. According to current evidence, assisted PCI has no advantage over main PCI. The role for pharmaco-invasive reperfusion, defined as pharmacological re-perfusion followed by rapid transfer for routine delayed coronary angiography and PCI may still be considered in centers without on-site PCI capability.
Patients presenting with STEMI in Nigeria have a lot of challenges which include delay in decision making, cost of revascularization, religious believes, ignorance and availability of cardiac catheterization and the skillful personnel for the operation. To meet with the demand and challenges of Myocardial infarction in Nigeria, we need the mode of treatment that is beneficial, cost effective and lifesaving. Hence, pharmaco-invasive is the way for Nigeria and other low-income countries of sub-Saharan Africa.

Published: October 2023

Aims: This study aimed to determine geomorphological characteristics of Kurumanpuzha sub-watershed for understanding its hydrological behaviour, erosion susceptibility and geological characteristics.
Study Design: Morphometric analysis of Kurumanpuzha sub-watershed was carried out using remote sensing and Geographic Information System (GIS) which is pivotal for sustainable resource management.
Place and Duration of Study: This study was conducted at Kelappaji College of Agricultural Engineering and Technology, Tavanur, Malappuram, Kerala during 2020-2021.
Methodology: The geomorphological characteristics of Kurumanpuzha sub-watershed were determined using GIS offering precise terrain insights to guide water resource planning, erosion control, infrastructure development and ecological conservation. Morphometric parameters were assessed based on linear, areal, and relief characteristics. USGS Earth Explorer platform was employed to download satellite images from multiple sources, including ISRO Resourcesat, Landsat, Sentinel, RADAR, and others. These images were then used to develop a Land Use Land Cover (LULC) map as well as other maps of the study area.
Results: The sub-watershed had a dendritic drainage pattern with a mean bifurcation ratio of 2.05, indicating easier flood management due to longer durations of low peak flows. The analysis revealed fine drainage, indicating a prevalence of soft rocks prone to erosion. The watershed had high relief and steep slopes, characterized by hills, breaks, and low mountains. The hypsometric curve indicated an equilibrium stage of geomorphic evolution. Morphometric parameters were grouped into three clusters at the sub-watershed level, demonstrating spatial variability. Forest/dense vegetation were the dominant land use, followed by rubber plantations and scrubland.
Conclusion: The findings of this study contribute to understanding of the hydrological behaviour, erosion susceptibility and geological characteristics of Kurumanpuzha sub-watershed. It is useful for effective watershed management, erosion control and informed decision-making in land use planning and engineering projects.
Nonparametric identification of Wiener system with a subclass of wide‐sense cyclostationary excitations
Authors: Mzyk Grzegorz , Maik Gabriel 
Published: October 2023

SummaryThe paper identifies a Wiener system, which is excited by a cyclostationary time series. To estimate the first subsystem's linear dynamic impulse response: this proposed algorithm first kernel‐windows the Wiener system's input measurements, then cross‐correlates with the output time series. To identify the second subsystem's static nonlinearity: this proposed algorithm first estimates the unobservable inter‐block internal signal (consistently in the statistical sense), and then kernel‐windows these estimates with the Wiener system output. This estimator provides the unusual capability to identify non‐invertible nonlinearities. This strategy removes any restrictive requirement for a Gaussian random excitation or a sinusoidal deterministic excitation. This paper further proves the estimator's asymptotic consistency and determines the kernel bandwidth for algorithmic convergence. The proposed algorithm's efficacy is verified in the context of two common applications: a servo mechanical system and a telecommunication channel.

AbstractA microstructural informed thermodynamic model is utilized to tailor the pseudoelastic performance of a series of Fe–Mn–Al–Ni shape‐memory alloys. Following this approach, the influence of the stability and the amount of the B2‐ordered precipitates on the stability of the austenitic state and the pseudoelastic response is revealed. This is assessed by a combination of complementary nanoindentation measurements and incremental‐strain tests under compressive loading. Based on these investigations, the applicability of the proposed models for the prediction of shape‐memory capabilities of Fe–Mn–Al–Ni alloys is confirmed. Eventually, these thermodynamic considerations enable the guided enhancement of functional properties in this alloy system through the direct design of alloy compositions. The procedure proposed renders a significant advancement in the field of shape‐memory alloys.

AbstractA multichannel/multicolor visible light communication (VLC) system using entirely organic components, including organic light emitting diodes (OLEDs) and organic photodiodes (OPDs), is developed to demonstrate indoor lighting applications where the integration of OLEDs and OPDs has significant potential. To achieve this, tricolor (Red/Green/Blue(R/G/B))‐selective OPD arrays for the receiver and tricolor OLED arrays for the emitter are developed. For (R/G/B)‐selective OPDs, a Fabry–Pérot electrode to enhance color selectivity and a thick junction structure to effectively accommodate a wide range of driving voltages are introduced. For tricolor OLEDs, fluorescent‐emitting materials are used to enhance the operating frequency in addition to introducing a cavity structure to achieve narrow emission. Utilizing these spectrally refined tricolor OPDs/OLEDs, a VLC system is designed for indoor lighting applications, and a systematic analysis of their signal‐to‐interference ratio dependence on the distance or angle between the transmitter and receiver is performed. The study's findings indicate the importance of emission angle‐dependent wavelength shift of the OLED and the luminosity function, which varies with wavelength, in the R/G/B mixed‐white‐light‐based VLC systems. Finally, the feasibility of VLC using tricolor OPDs/OLEDs in the real‐life context of indoor white‐color lighting is demonstrated, showing that the transmitted data patterns well‐matched the received data patterns.

AbstractMalnutrition due to macro‐ and micro‐nutrient deficiencies is one of the major global health concerns, especially in developing countries. Using genomics‐assisted breeding to enhance the nutritional value of important crops such as chickpea (Cicer arietinumL.) can help to address the problem. In this study, we conducted genome‐wide association studies to identify genes associated with protein, starch, oil, and fiber in chickpea to create resources to speed the breeding process. The USDA kabuli chickpea mini‐core of 88 accessions was genotyped using genotyped‐by‐sequencing, and 36,645 single nucleotide polymorphisms (SNPs) were identified across the eight chromosomes of the chickpea genome. A genome‐wide marker‐trait analysis using the FarmCPU model was conducted to identify SNP markers that can enable marker‐assisted breeding for seed protein, fiber, oil, and starch concentrations. The most significantly associated markers for seed protein concentration (p = 8.82E‐12), starch (p = 2.79E‐12), fiber (p = 7.65E‐12), and oil (p = 1.37E‐08) were found on chromosomes 1, 2, 6, and 7, controlling 11%, 12%, 20%, and 16% of the phenotypic variation, respectively. Validation of the SNP markers in a broader set of plant genetic resources and environments will be needed to determine their usefulness in breeding for end‐use characteristics.
High‐Energy Aqueous/Organic Hybrid Batteries Enabled by Cu2+ Redox Charge Carriers
Authors: Bi Songshan , Zhang Yanyu , Wang Huimin , Tian Jinlei , Niu Zhiqiang 
Published: October 2023

AbstractLithium||sulfur (Li||S) batteries are considered as one of the promising next‐generation batteries due to the high theoretical capacity and low cost of S cathodes, as well as the low redox potential of Li metal anodes (−3.04 V vs. standard hydrogen electrode). However, the S reduction reaction from S to Li2S leads to limited discharge voltage and capacity, largely hindering the energy density of Li||S batteries. Herein, high‐energy Li||S hybrid batteries were designed via an electrolyte decoupling strategy. In cathodes, S electrodes undergo the solid‐solid conversion reaction from S to Cu2S with four‐electron transfer in a Cu2+‐based aqueous electrolyte. Such an energy storage mechanism contributes to enhanced electrochemical performance of S electrodes, including high discharge potential and capacity, superior rate performance and stable cycling behavior. As a result, the assembled Li||S hybrid batteries exhibit a high discharge voltage of 3.4 V and satisfactory capacity of 2.3 Ah g−1, contributing to incredible energy density. This work provides an opportunity for the construction of high‐energy Li||S batteries.

Published: October 2023

AbstractA tandem three‐component C−H bond addition involving the activation of an inert C(sp3)−H bond is reported. The process enables the direct regioselective synthesis of 1,2‐difunctionalized arenes with the formation of C(sp3)− and C(sp2)−C(arene) bonds. 2‐Iodobenzoic acid derivatives behave as masked bifunctional reagent (BFR) and react with 2‐pyridyl‐methyl sulfoximine (MPyS) protected aliphatic acids bearing α,α‐disubstituted groups, and alkenes to produce β‐aryl‐δ‐alkenyl amide derivatives in a single operation. The transformation involves Pd(II)/Pd(IV) and Pd(II)/Pd(0) catalytic systems. Detailed mechanistic studies, including density functional theory (DFT) calculations, reveal the formation of large T‐shaped palladacycles and the onset of a 1,2‐palladium migration via decarboxylation.
Kinetik der thermischen Zersetzung und Bildung von Stickoxyd. I. Teil
Authors: Veiter Klaus 
Published: October 2023

AbstractEs wird die Reaktionsgeschwindigkeit der thermischen Zersetzung von Stickoxyd im Temperaturbereich von 1180° bis 1912° abs. in Abwesenheit von Katalysatoren nach einer Strömungsmethode gemessen. Die Reaktion wird nicht, wie bisher angenommen, von der 2. Ordnung in bezug auf NO gefunden. Sie ist daher nicht als bimolekulare Reaktion NO+NO → N2 + O2 zu deuten. Ein Einfluß von O2 und N2 auf die Reaktionsgeschwindigkeit wird gefunden und untersucht. Es ergibt sich, daß O2 die Reaktionsgeschwindigkeit vergrößert, und daß die Reaktionsgeschwindigkeitskonstante 2. Ordnung noch von dem Konzentrationsverhältnis [NO]/[O2] abhängt.Die Anwendung verschiedener Berechnungsarten, die aus der Annahme von Mischung oder Nichtmischung der Reaktionsgase im Reaktionsgefäß folgen, wird behandelt und ihr Einfluß auf das Ergebnis untersucht.Die experimentellen Ergebnisse werden durch ein Reaktionsschema gedeutet, dessen Einzelreaktionen Atom‐reaktionen sind, in denen O‐ bzw. N‐Atome gebildet oder verbraucht werden, und die darauffolgend in kurzen Reaktionsketten weiterreagieren. Auf Grund dieses Reaktionsmechanismus wird eine Gleichung für die Reaktionsgeschwindigkeit hergeleitet, die in guter Übereinstimmung mit den gefundenen Geschwindigkeitswerten steht und einen Ausdruck für die Gleichgewichtskonstante liefert.

AbstractDie Anderung des Rückstandes bzw, des Destillates im Verlaufe der Rektifikation eines Dreistoffsystems ohne Mischungslücke läßt sich durch die Rektifikationslinien bzw. Destillatlinien darstellen. Diese werden in Zusammenhang gebracht mit den analogen Linien, die man bei der einfachen Destillation zeichnen kann. So ist es möglich, vorliegende Rektifikationsuntersuchungen an komplizierten Dreistoffsystemen zu deuten und unter einheitlichen Gesichtspunkten zu ordnen.
Die Thermodiffusion vom Standpunkt der Thermodynamik irreversibler Prozesse
Authors: Haase Rolf 
Published: October 2023

AbstractDer Gültigkeitsbereich der modernen thermodynamischen Theorie der irreversiblen Prozesse ist nach Untersuchungen von Prigogine – wenigstens für Case–weitgehend präzisierbar. Die Methodik der Theorie läßt sich auf ein einfaches Schema bringen (Meixner, Prigogine).Für die Phänomene der Thermodiffusion, des Diffusionsthermoefektes und der Druckdiffusion sind generelle Zusammenhänge herleitbar, die für beliebige Flüssigkeits‐ und Gasgemische gelten und daher die bisher aufgestellten Beziehungen (Onsager, Meixner, Prigogine) als Sonderfälle enthalten. In der vorliegenden Arbeit werden über folgende Probleme für binäre Gemische allgemeine Aussagen gewonnen: Beziehung der Druckdiffusion zur gewöhnlichen Diffusion, Zusammenhang zwischen der Wärmeleitfähigkeit bei verschwindendem Druck‐ und Konzentrationsgefälle und derjenigen im stationären Zustand, Beziehung zwischen Thermodiffusion und Diffusionsthermoeffekt, Ungleichung für den Thermodiffusionsfaktor, Vorzeichen des Druckdiffusionskoeffizienten, thermodynamischer Wirkungsgrad der Thermodiffusion, Änderung der lokalen Entropieerzeugung während eines Thermodiffusionsprozesses. In allen Fällen, in denen kinetische Rechnungen durchführbar sind, ergibt sich Übereinstimmung zwischen der kinetischen und der thermodynamisch‐phänomenologischen Theorie.

Published: October 2023

AbstractEs wird der Einfluß von Salzen auf das Potential massiver Wismutstäbe bzw. von Graphitelektroden, die elektrolytisch mit Wismut überzogen waren, im pH‐Bereich 3–14 untersucht. Eine pH‐Verschiebung wird nur im sauren Bereich beobachtet. Wismutionen sind ohne Einfluß auf das Potential. Oxydierende und reduzierende Stoffe beeinflussen das Potential nur, wenn ihr rH‐Wert kleiner als 18 oder größer als 40 ist. Das Potentialverhalten wird auf der Grundlage des Vorganges Bi + 3OH′ ⇋ Bi (OH)3 + 3 Θ diskutiert.
Über den Einbau von Schwefel bei der elektrolytischen Abscheidung von Kupfer aus Kupfersulfatlösung und die Messung des Ionenradius bei der Bildung monomolekularer Oberflächenschichten
Authors: Houtermans F. G. , Vincent D. , Wagner G. 
Published: October 2023

AbstractMit S35 als Indikator wird der Einbau von Schwefel bei der elektrolytischen Abscheidung von Kupfer untersucht. Dabei stellt sich heraus, daß 1. sowohl auf der Kathode als auf der Anode eine stark aktive Oberflächenschicht ausgebildet wird, deren Aktivität sich quantitativ durch Annahme einer monomolekularen Schicht von SO4‐Ionen erklären läßt, die die Oberfläche vollkommen bedeckt. Der sich hierbei unter Annahme dichtester Kreispackung ergebende Ionenradius des SO4‐Ions stimmt gut mit dem von Eucken und Wolf gegebenen überein. 2. In das kathodisch abgeschiedene Cu wird, je nach dem Verlauf der Elektrolyse 10−8 bis 10−5 g S/gCu eingebaut. Der Einbau scheint durch die Bildung von Cu2O begünstigt zu werden.
