Published: August 2024

Today, many institutions and individuals are paying attention to the development of technologies used in sustainable agriculture. One of the technologies is eco-enzyme that can be used as organic fertilizer. Several researchers have studied the use of eco-enzymes in agriculture, but studies on the nutrient content of eco-enzymes are still very limited. This research was conducted to investigate the nutrient content of two eco-enzyme preparations. The eco-enzymes were produced through the fermentation process of water, fruit peels, and molasses with a weight ratio of 10 : 3 : 1. Fruit peels used for Eco-enzyme A were banana, melon, watermelon, orange, and pineapple peels, while for Eco-enzyme B were banana, mango, watermelon, orange, and pineapple peels. The fermentation period for Eco-enzyme A was seven months, while for Eco-enzyme B was eight months. The results of the analysis showed that the two eco-enzymes contained various nutrients, both macro (C, N, P, K, Mg, Ca) and micro (Mn, Zn, B, Fe, Cu) ones, that were consistently higher in Eco-enzyme A. Both eco-enzymes were acidic, where the pH of Eco-enzyme A and B were 3.95 and 3.50, respectively. The data obtained were expected to be a basic reference for further research on eco-enzymes.

Published: August 2024

Kenaikan harga beras di Gorontalo diakibatkan stok beras di pasar semakin berkurang dapat menyebabkan ketidakoptimalan dalam rantai pasok beras untuk memenuhi permintaan konsumen, yang pada gilirannya akan berdampak pada kinerja keseluruhan rantai pasok beras. Tujuan penelitian untuk mengetahui struktur dan efisiensi rantai pasok beras di Gorontalo. Penelitian dilaksanakan dari bulan April-Juli 2023 Provinsi Gorontalo. Metode penelitian menggunakan metode survei. Pengambilan sampel dilakukan dengan metode multistage sampling dari 2 Kabupaten kemudian dari masing-masing kabupaten dipilih 2 kecamatan yang memiliki produksi padi tertinggi. Berdasarkan data dari petani, teridentifikasi aliran produk beras yang melibatkan berbagai lembaga lainnya yaitu 13 unit penggilingan, 7 orang pedagang besar, 10 orang pedagang pengecer, TTIC, BULOG dan 4 toko Alfamart. Struktur rantai pasok beras di Gorontalo dianalisis deskriptif kualitatif. Sedangkan efisiensi teknis setiap pelaku rantai pasok dianalisis dengan metode DEA (Data Envelopment Analysis). Hasil penelitian menunjukkan struktur rantai pasok komoditas beras di Gorontalo terbagi atas empat model rantai pasokan yang melibatkan petani, penggilingan padi, pedagang besar, pengecer, BULOG, TTIC dan Alfamart, dimana pelaku yang menjadi grower adalah petani, BULOG, TTIC dan Alfamart. Secara garis besar pelaku rantai pasok beras di Provinsi Gorontalo memiliki kinerja yang efisien, kecuali petani dan penggilingan yang berada di Kecamatan Tolangohula dimana metrik kinerja yang tidak efisien pada tingkat petani adalah semua faktor input kecuali cost, sedangkan pada tingkat penggilingan padi, metrik kinerja yang tidak efisien adalah siklus cash to cash dan cost. Efisiensi kinerja rantai pasokan bisa diatasi dengan meningkatkan kinerja rantai pasokan, dengan mengurangi input dan meningkatkan output.

Revisiting the Tertiary-induced Binary Black Hole Mergers: The Role of Superthermal Wide Tertiary Eccentricity Distributions
Authors: Su Yubo , Liu Bin , Xu Siyao 
Published: August 2024

Abstract
Recent studies show that the eccentricity distribution of wide binaries (semimajor axis ≳103 au) observed by Gaia tends to favor large eccentricities more strongly than the canonical thermal distribution (P(e) ∝ e)—such distributions are termed “superthermal.” Motivated by this observation, we revisit the formation channel of black hole (BH) binary mergers in triple stellar systems and study the impact of superthermal eccentricity distributions in the outer binaries. We explore the persistence of the highly eccentric outer orbits after each component in a stellar triple has undergone mass loss due to supernova explosions. We find that the outer eccentricity distribution can remain significantly superthermal for modestly hierarchical BH triples satisfying a
in/a
out ≳ 0.005 (where a
in and a
out are the semimajor axes of the inner and outer orbits), and are otherwise shaped by mass-loss induced kicks and dynamical instability. We then study the impact of these different outer eccentricity distributions of the remaining BH triples on mergers via the tertiary-induced channel. Of interest, we find that mergers can sometimes be produced even when the initial stellar orbits are near alignment (not subject to the von-Zeipel–Lidov–Kozai effect; ZLK effect) as long as the system is sufficiently hierarchical. On the other hand, although the impact of the octupole-order ZLK effect is much greater when the outer binary is more eccentric, we find that the merger fraction only changes modestly for extreme outer eccentricity distributions because the largest eccentricities tend to lead to dynamical instability.
Perturbation Spectra of Warm Inflation in f(Q, T) Gravity
Authors: Shiravand Maryam , Farhoudi Mehrdad , Goodarzi Parviz 
Published: August 2024

Abstract
We investigate the warm inflationary scenario within the context of the linear version of f(Q, T) gravity, coupled with both the inflaton scalar field and the radiation field, under the conditions of the strong dissipation regime. First, we calculate the modified Friedmann equations and the modified slow-roll parameters. Subsequently, we apply the slow-roll approximations to derive the scalar power spectrum and the tensor power spectrum. Also, we develop formulations of the scalar and tensor perturbations for the f(Q, T) gravity with the warm inflation scenario. Furthermore, we scrutinize two different forms of the dissipation coefficient, a constant and a function of the inflaton field, to determine the scalar spectral index, the tensor-to-scalar ratio, and the temperature for the power-law potential case. By imposing some constraints on the free parameters of the model, we attain results in good agreement with both the Planck 2018 data and the joint Planck, BK15, and baryon acoustic oscillation data for the tensor-to-scalar ratio, and consistent results aligned with the Planck 2018 data for the scalar spectral index. In addition, the obtained results are within the range of observational data for the amplitude of the scalar power spectrum. Consequently, we are able to revive the power-law potential that was previously ruled out by observational data. Moreover, for both dissipation coefficients, the model leads to a scalar spectral index with the blue and red tilts in agreement with the Wilkinson Microwave Anisotropy Probe 3 yr data.

Abstract
Rings and gaps are among the most widely observed forms of substructure in protoplanetary disks. A gap–ring pair may be formed when a planet carves a gap in the disk, which produces a local pressure maximum following the gap that traps inwardly drifting dust grains and appears as a bright ring owing to the enhanced dust density. A dust-trapping ring would provide a promising environment for solid growth and possibly planetesimal production via the streaming instability. We present evidence of dust trapping in the bright ring of the planet-hosting disk Elias 2-24, from the analysis of 1.3 and 3 mm Atacama Large Millimeter/submillimeter Array observations at high spatial resolution (0.″029, 4.0 au). We leverage the high spatial resolution to demonstrate that larger grains are more efficiently trapped and place constraints on the local turbulence (8 × 10−4 < α
turb < 0.03) and the gas-to-dust ratio (Σ
g
/Σ
d
< 30) in the ring. Using a scattering-included marginal probability analysis, we measure a total dust disk mass of

. We also show that at the orbital radius of the proposed perturber the gap is cleared of material down to a flux contrast of 10−3 of the peak flux in the disk.
MULTI-OBJECTIVE OPTIMIZATION STUDY OF RESIDENTIAL ENERGY CONSUMPTION BASED ON EDH AND THE STOCHASTIC OPERATION OF AIR CONDITIONING
Authors: Dang Yichen , Yao Jian 
Published: August 2024

ABSTRACT
Current requirements for residential energy-efficient design solutions in China are relatively homogeneous, requiring only improvements in overall building energy performance, often ignoring the energy differences between different residential housing units. This paper proposes a multi-objective research framework based on an occupant behavior model of air conditioning and a Non-dominated Sorting Genetic Algorithm-II (NSGA-II) to study energy-efficient design solutions for residential envelopes. The optimal energy-saving design scheme has a 22.56% and 35.34% reduction in energy consumption difference between residential units and overall building energy consumption, respectively, both of which have been optimized substantially. Moreover, the overall energy performance of the building can be improved when the “energy performance difference between housing units” (EDH) is reduced, which verifies that EDH is an important criterion for improving the energy performance of residential housing units.
QUANTIFICATION OF CARBON POTENTIAL OF CONSTRUCTION WASTE TREATMENT: A CASE STUDY OF GUANGZHOU, CHINA
Authors: Liu Jingkuang , Tan Xiaomin , Zheng Jiaxi , Wang Zhenshuang 
Published: August 2024

ABSTRACT
Emission reduction in the construction sector is essential for China to achieve its carbon peaking and carbon neutrality goals. Construction waste recycling represents an important step in reducing the construction industry’s carbon emissions; however, construction waste recycling potential has received little attention from the industry to date. This paper adopts the Life Cycle Assessment method, constructs a carbon potential quantification formula for different construction waste treatment modes, and evaluates the economic benefit of these methods. The study’s main results are as follows. (1) For each unit (t) of construction waste disposal, the carbon potential of close-range off-site recycling is the lowest, that of public landfill is the highest, and that of recycling is intermediate. (2) The economic benefit evaluation shows that under the same conditions, the lowest total disposal cost for construction waste per unit (t) is via recycling and resourcing, indicating that this approach combines economic benefits, environmental friendliness, and sustainability. (3) Eco-friendly bricks produced by construction waste recycling have reduced carbon potential requirements compared to traditional bricks; thus, the construction waste treatment process plays a successful role in reducing carbon potential. This study’s conclusions enrich and improve the theory of construction waste resource management and can be used as a reference basis for the government to formulate emission reduction strategies for the construction industry and provide guidance for enterprises related to construction waste recycling.
Waist-based anthropometric measures and central adiposity-related comorbidities in children
Authors: Gomwe Howard , Phiri Lesego , Marange Chioneso S. 
Published: August 2024

Background: Waist-related measures are commonly used to classify central adiposity and related comorbidities. This classification may be essential among children, as it may identify the risk of future non-communicable diseases.Methods: A cross-sectional study was conducted in the Eastern Cape province, South Africa, among 459 primary school learners aged 9–14 years. Height, weight and waist circumference (WC) were measured using standardised techniques recommended by World Health Organization (WHO). The anthropometric measurements, including body mass index (BMI), WC, waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) were computed and evaluated.Results: Most participants were girls (57.70%) with an average age of 11.20 ± 1.60 years. The average weight was 38.81 kg ± 10.49 kg with an average height of 144.16 (standard deviation [s.d.] = 10.37) cm. The sample had a BMI of 18.41 kg/m2 (s.d. = 3.19). The results showed, on average, WC of 62.10 cm ± 8.12 cm, WHR of 0.82 ± 0.15 and WHtR of 0.44 ± 0.05. Girls reported significantly higher BMI, WC and WHtR. Based on WHtR, the results showed the acceptable ability to classify children according to abdominal obesity, thus identifying their risk for comorbidities.Conclusion: Overall body fat indicated by BMI and central obesity shown by waist-related anthropometric measures can play a significant role in classifying children in terms of their risk of comorbidities.Contribution: To prevent the risks of metabolic diseases in childhood, it is necessary to detect abdominal obesity early using WC-based anthropometric measurements, especially WHtR, to identify those at risk.
A behind-the-scenes role of BDNF in the survival and differentiation of spermatogonia

Abstract
Mouse spermatogenesis entails the maintenance and self-renewal of spermatogonial stem cells (SSCs), which require a complex web-like signaling network transduced by various cytokines. Although brain-derived neurotrophic factor (BDNF) is expressed in Sertoli cells in the testis, and its receptor tropomyosin receptor kinase B (TrkB) is expressed in the spermatogonial population containing SSCs, potential functions of BDNF for spermatogenesis have not been uncovered. Here, we generate BDNF conditional knockout mice and find that BDNF is dispensable for in vivo spermatogenesis and fertility. However, in vitro, we reveal that BDNF-deficient germline stem cells (GSCs) exhibit growth potential not only in the absence of glial cell line-derived neurotrophic factor (GDNF), a master regulator for GSC proliferation, but also in the absence of other factors, including epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), and insulin. GSCs grown without these factors are prone to differentiation, yet they maintain expression of promyelocytic leukemia zinc finger (Plzf), an undifferentiated spermatogonial marker. Inhibition of phosphoinositide 3-kinase (PI3K), mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK), and Src pathways all interfere with the growth of BDNF-deficient GSCs. Thus, our findings suggest a role for BDNF in maintaining the undifferentiated state of spermatogonia, particularly in situations where there is a shortage of growth factors.

Abstract
Depression currently affects about 280 million people worldwide and its prevalence has been increasing dramatically, especially among the young and people of reproductive age, which consequently leads to an increase in antidepressant consumption. Antidepressants are associated with sexual dysfunction in both men and women; however, their role in male fertility has been scarcely studied. Fluoxetine and sertraline, two serotonin reuptake inhibitors (SSRIs), are among the most prescribed antidepressants worldwide. To determine their possible effects, human sperm cells were exposed to either sertraline or fluoxetine at concentrations previously found in blood and seminal fluid of patients undergoing treatment. Spermatozoa were incubated for up to 24 h at 37°C and 5% CO2, and important functional parameters such as sperm motility, viability, mitochondrial membrane potential, cellular reactive oxygen species (ROS) production, chromatin/DNA integrity, acrosome status, and tyrosine phosphorylation were assessed. At low levels, fluoxetine consistently decreased progressive motility throughout time while promoting fluctuations in ROS levels and sperm capacitation. Nevertheless, it did not affect viability, mitochondrial membrane potential, acrosome reaction nor chromatin/DNA integrity. Sertraline, on the other hand, had little to nonsignificant impact at low doses, but affected almost all tested parameters at supratherapeutic concentrations. Altogether, our results suggest that both antidepressants may impair sperm function, possibly through different mechanisms of action, but fluoxetine is the only exhibiting mild negative effects at doses found in vivo.

ABSTRACT

Objective:
This retrospective study aimed to determine the effect of liraglutide on weight and HbA1c levels in patients with type 2 diabetes mellitus (T2DM) in Saudi Arabia. The present investigation was carried out at a medical facility located in the Kingdom of Saudi Arabia.

Materials and Methods:
A retrospective analysis was conducted on the clinical records of 290 patients who were diagnosed with T2DM and were above 18 years of age. These patients were administered liraglutide for a minimum of 6 months. The dataset comprised various parameters such as the duration of diabetes, duration of liraglutide therapy, weight, and multiple biochemical markers such as HbA1c and low-density lipoprotein cholesterol levels. These parameters were measured both before and after the administration of liraglutide therapy.

Results:
The primary metrics evaluated in this study were alterations in body weight and levels of glycated hemoglobin (HbA1c). Over the 24-month observational period, significant reductions in body mass index (38.6 kg/m2 to 37 kg/m2), body weight (99.3 kg to 96 kg), and HbA1c levels (8.9% to 7.8%) (all P < 0.01) were seen.

Conclusion:
Liraglutide reduced HbA1c levels and weight and affected multiple metabolic markers in patients with T2DM in a real-world setting in Saudi Arabia.
Business manager training and employee support
Authors: Desgré Mathieu , Gaymard Sandrine 
Published: August 2024

The world is changing, and with it the way we work and how we relate to our work. Businesses face many challenges to which they must adapt if they hope to remain competitive. In addition to the question of an ecological transition, respect for human rights and working conditions is essential. Today, faced with recruitment difficulties and turnover issues, well-being and the quality of life in the workplace have become priorities for companies that wish to maintain their attractiveness and keep their current employees; in this context, motivation is an essential variable. As such, it is necessary to look into current managerial practices and skills and their underlying factors. In this context, we are interested in the impact of managerial practices on employees. The two principal means of becoming a manager are to be promoted “internally” or recruited externally; these two manager profiles differ in training, professional experience and organizational culture. Stemming from the theoretical field of social psychology, notably the “Five core social motives” model (Fiske, 2003), we reflect upon the issue of managerial practices in the context of a France-based business.
