A Finite Difference Method for Solving the Wave Equation with Fractional Damping
Authors: Cui Manruo , Ji Cui-Cui , Dai Weizhong
Published: December 2023

In this paper, we develop a finite difference method for solving the wave equation with fractional damping in 1D and 2D cases, where the fractional damping is given based on the Caputo fractional derivative. Firstly, based on the weighted method, we propose a new numerical approximation for the Caputo fractional derivative and apply it for the 1D case to obtain a time-stepping method. We then develop an alternating direction implicit (ADI) scheme for the 2D case. Using the discrete energy method, we prove that the proposed difference schemes are unconditionally stable and convergent in both 1D and 2D cases. Finally, several numerical examples are given to verify the theoretical results.

Published: December 2023

Background and Objectives: While systematic reviews highlight the advantages of laparoscopic nephrectomy over traditional open surgery, the impact of an assistant’s experience on surgical outcomes remains unclear. This study aims to evaluate whether the level of assistant expertise influences laparoscopic nephrectomy outcomes. Materials and Methods: Retrospective data from our institutional database were analyzed for patients who underwent laparoscopic nephrectomy between January 2018 and December 2022. Procedures were performed by a highly experienced surgeon, including postgraduate year (PGY)-3 to PGY-5 residents as assistants. Senior-level assistants had completed at least 10 procedures. Patient characteristics, surgical outcomes, and postoperative details were collected. Multivariable linear and logistic regression models were performed to test the effect of assistant experience (low vs. high) on estimated blood loss (EBL), length of stay (LOS), operative time (OT), and postoperative complications. Results: 105 patients were included, where 53% had highly experienced assistants and 47% had less experienced ones. Low assistant experience and higher BMI predicted longer operative time (OT), confirmed by multivariable regression (β = 40.5, confidence interval [CI] 18.7–62.3, p < 0.001). Assistant experience did not significantly affect EBL or LOS after adjusting for covariates (β = −14.2, CI −91.8–63.3, p = 0.7 and β = −0.83, CI −2.7–1.02, p = 0.4, respectively). There was no correlation between assistant experience and postoperative complications. Conclusions: Assistant experience does not significantly impact complications, EBL, and LOS in laparoscopic nephrectomy. Surgeries with less experienced assistants had longer OT, but the overall clinical impact seems limited. Trainee involvement remains safe, guided by experienced surgeons.

Published: December 2023

Background and Objectives: While suspension training devices are increasingly gaining popularity, there is limited evidence on their effects on balance, and no comprehensive assessment has been conducted. This study aimed to evaluate the effects of a 9-session suspension training program on dynamic and static balance, stability, and functional performance. Materials and Methods: A total of forty-eight healthy adults, aged between 18 and 30, participated in a 9-session suspension training program. The program included exercises targeting upper and lower body muscles as well as core muscles. Balance was comprehensively assessed using various dynamic balance tests, including the Y Balance Test (YBT) as the primary outcome, single-leg Emery test, and sideways jumping test. Static balance was evaluated through the monopedal and bipedal Romberg tests. Changes from baseline were analyzed using a one-way ANOVA test. Results: Thirty-nine participants (mean age: 21.8 years) completed the intervention. The intervention resulted in significant improvements in YBT, jumping sideways, Emery, and 30s-SST scores (p < 0.001). Platform measures indicated enhanced monopedal stability (p < 0.001) but did not show a significant effect on bipedal stability (p > 0.05). Conclusions: Suspension training is a safe and feasible method for improving dynamic balance and functional performance in healthy, untrained young adults. However, it does not appear to significantly impact the ability to maintain a static posture while standing.
Modeling the Market-Driven Composition of the Passenger Vehicle Market during the Transition to Electric Vehicles
Authors: Mittal Vikram , Shah Rajesh
Published: December 2023

The automotive market is currently shifting away from traditional vehicles reliant on internal combustion engines, favoring battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs). The widespread acceptance of these vehicles, especially without government subsidies, hinges on market dynamics, particularly customers opting for vehicles with the lowest overall cost of ownership. This paper aims to model the total cost of ownership for various powertrains, encompassing conventional vehicles, HEVs, PHEVs, and BEVs, focusing on both sedans and sports utility vehicles. The modeling uses vehicle dynamics to approximate the fuel and electricity consumption rates for each powertrain. Following this, the analysis estimates the purchase cost and the lifetime operational cost for each vehicle type, factoring in average daily mileage. As drivers consider vehicle replacements, their choice tends to lean towards the most economical option, especially when performance metrics (e.g., range, acceleration, and payload) are comparable across the choices. The analysis seeks to determine the percentage of drivers likely to choose each vehicle type based on their specific driving habits. Advances in battery technology will reduce the battery weight and cost; further, the cost of electricity will decrease as more renewable energy sources will be integrated into the grid. In turn, the total cost of ownership will decrease for the electrified vehicles. By following battery trends, this study is able to model the makeup of the automotive market over time as it transitions from fossil-fuel based vehicles to fully electric vehicles. The model finds until the cost of batteries and electricity is significantly reduced, the composition of the vehicle market is a mixture of all vehicle types.

Authors: Lee Youngseo , Lee Jihye , Lee Kang-Bong , Lee Won-Yong , Lee Yeonhee
Published: December 2023

Lacquer sap has been traditionally used in coatings and artwork. Suitable types of lacquer are required to preserve and restore artifacts. Recently, unsuitable cashew nut shell liquid (CNSL) has often been mixed with lacquer sap, so it is necessary to identify the characteristics of lacquer sap by the production area. However, research is still focused on urushiol and laccol. In this study, Myanmarese lacquer sap collected from Gluta usitata, which contains thitsiol as the main component, was analyzed by HPLC to quantify thitsiol using the standards 3-(10-phenyldecyl) benzene-1,2-diol (thitsiol 16) and 3-(8Z,11Z-pentadecadienyl)-benzenediol (urushiol 15:2) as markers, and calibration curves were plotted. The coefficients of determination (R2) for thitsiol 16 and urushiol 15:2 were 0.9985 and 0.9983, respectively. In addition, a blind test was conducted to confirm that accurate quantitative analysis was possible even when Myanmarese lacquer was mixed with lacquer from another production area, which contained urushiol as the main component, and CNSL, which contained cardol, a completely different catechol. Quantitative analysis of thitsiol 16 and urushiol 15:2 in Myanmarese lacquer using HPLC can be used to evaluate the quality of lacquer sap and for more sophisticated activities such as restoration by classifying differences in lacquer sap by the production area.

Published: December 2023

Photochromic compounds, whose key molecular properties can be effectively modulated by light irradiation, have attracted significant attention for their potential applications in various research fields. The restriction of photoisomerization coloration induced by ultraviolet light limits their applications in the biomedical field and some other fields. Negative photochromism, wherein a relatively stable colored isomer transforms to a colorless metastable isomer under low–energy light irradiation, offers advantages in applications within materials science and life science. This review provides a summary of negatively photochromic compounds based on different molecular skeletons. Their corresponding design strategies and photochromic properties are presented to provide practical guidelines for future investigations. Negatively photochromic compounds can effectively expand the range of photochromic switches for future applications, offering unique properties such as responsiveness to visible to near–infrared light.

Published: December 2023

This study investigates the potential of two algae species from different genera, namely the recently isolated Scenedesmus obliquus BGP and Porphyridium cruentum, from the perspective of their integral sustainable transformation to valuable substances. Conventional Soxhlet and environmentally friendly supercritical fluid extraction were applied to recover oils from the species. The extracts were characterized through analytical techniques, such as GC-Fid and LC-MS/MS, which allowed their qualitative and quantitative differentiation. Thus, P. cruentum oils contained up to 43% C20:4 and C20:5 fatty acids, while those of S. obliquus BGP had only residual amounts. The LC-MS/MS analysis of phenolic compounds in the S. obliquus BGP and P. cruentum extracts showed higher content of 3-OH-4-methoxybenzoic acid and kaempferol 3-O-glycoside in the former and higher amounts of ferulic acid in the latter. Total phenolic content and antioxidant activity of the oils were also determined and compared. The compositional analysis of the oil extracts revealed significant differences and varying potentialities based on their genera and method of extraction. To the best of our knowledge our work is unique in providing such detailed information about the transformation prospects of the two algae species to high-value chemicals and bioproducts.

Published: December 2023

Several foods are used in both the nutraceutical and health sectors; vegetable oils, for example, can prevent the onset of numerous diseases. The properties of these oils are related to their chemical composition and primarily to the presence of fatty acids. The present work aimed to determine the chemical profiles of Argania spinosa, Pinus halepensis, and Pistacia altantica oils, used in traditional Tunisian foods, and to evaluate some biological properties. We evaluated their antioxidant, anti-enzymatic, antimicrobial, and anti-inflammatory properties. Linoleic acid was the main component of the three oils. P. atlantica oil showed more significant inhibitory activity against the enzymes studied than A. spinosa and P. halepensis. All three oils showed similar antioxidant and anti-inflammatory activity. Furthermore, A. spinosa and P. halepensis oils showed antibiofilm activity against P. aeruginosa, with 30–40% inhibition. These results focus on the possible use of these oils in the nutraceutical and healthcare sectors.

Published: December 2023

A synthetic pathway to a novel 4-aryl-3,4-dihydro-2H-1,4-benzoxazine scaffold was developed and a series of compounds based on the scaffold were synthesised as potential anticancer agents. The 4-aryl-substituted compounds were prepared via Buchwald–Hartwig cross-coupling between substituted bromobenzenes and various 1,4-benzoxazines, which in turn were generated from a cascade hydrogenation and reductive amination one-pot reaction. These analogues exhibited moderate to good potency against various cancer cell lines. Structure–activity relationship analysis indicated that the inclusion of hydroxyl groups on ring A and ring B was beneficial to biological activity, while having a para-amino group on ring C significantly enhanced potency. Molecule 14f displayed the most potent anticancer activity (IC50 = 7.84–16.2 µM against PC-3, NHDF, MDA-MB-231, MIA PaCa-2, and U-87 MG cancer cell lines), indicating its potential as a lead compound for further structural optimisation. All the synthesised compounds were fully characterised with NMR, HMRS, and IR. The novel benzoxazine scaffold described in this study holds promise and deserves further in-depth studies.

Published: December 2023

The food sector’s interest in sustainability and the demand for novel bioactive compounds are increasing. Many fruits are wasted every year before ripening due to various climatic conditions and harsh weather. Unripe mangoes, grapes, and black lemons could be rich sources of phenolic compounds that need to be fully elucidated. Using fruit waste as a source of bioactive chemicals has grown increasingly appealing as it may have significant economic benefits. Polyphenols are beneficial for human health to inhibit or minimize oxidative stress and can be used to develop functional and nutraceutical food products. In this context, this study aimed to characterize and screen unripe mangoes, grapes, and black lemons for phenolic compounds using LC-ESI-QTOF-MS/MS and their antioxidant activities. Unripe mangoes were quantified with higher total phenolic content (TPC, 58.01 ± 6.37 mg GAE/g) compared to black lemon (23.08 ± 2.28 mg GAE/g) and unripe grapes (19.42 ± 1.16 mg GAE/g). Furthermore, unripe mangoes were also measured with higher antioxidant potential than unripe grapes and black lemons. A total of 85 phenolic compounds (70 in black lemons, 49 in unripe grapes, and 68 in unripe mango) were identified, and 23 phenolic compounds were quantified using LC-MS/MS. Procyanidin B2, gallic acid, epicatechin, caffeic acid, quercetin, and chlorogenic acid were measured with higher concentration in these selected unripe fruits. A positive correlation was found between phenolic contents and the antioxidant activities of unripe fruits. Furthermore, chemometric analysis was conducted to validate the results. This study will explore the utilization of these unripe fruits to develop functional and therapeutic foods.
Crystallinity, Rheology, and Mechanical Properties of Low-/High-Molecular-Weight PLA Blended Systems
Authors: Yang Hongwei , Du Jianghua
Published: December 2023

As semi-crystalline polyester (lactic acid) (PLA) is combined with other reinforcing materials, challenges such as phase separation, environmental pollution, and manufacturing difficulties could hinder the benefits of PLA, including complete biodegradability and strong mechanical properties. In the present investigation, melt blending is utilized to establish a mixture of low- and high-molecular-weight polylactic acids (LPLA and HPLA). The crystallinity, rheology, and mechanical properties of the combination were analyzed using rotational rheometry, differential scanning calorimetry, X-ray diffraction, polarized optical microscopy, scanning electron microscopy, and universal testing equipment. The results demonstrate compatibility between LPLA and HPLA. Moreover, an increase in LPLA concentration leads to a decrease in the crystallization rate, spherulite size, fractional crystallinity, and XRD peak intensity during isothermal crystallization. LPLA acts as a diluent during isothermal crystallization, whereas HPLA functions as a nucleating agent in the non-isothermal crystallization process, promoting the growth of LPLA crystals and leading to co-crystallization. The blended system with a 5% LPLA mass fraction exhibits the highest tensile strength and enhances rheological characteristics. By effectively leveraging the relationship between various molecular weights of PLA’s mechanical, rheological, and crystallization behavior, this scrutiny improves the physical and mechanical characteristics of the material, opening up new opportunities.

Authors: Di Matteo Paola , Petrucci Rita , Curulli Antonella
Published: December 2023

Two-dimensional (2D) nanomaterials (e.g., graphene) have attracted growing attention in the (bio)sensing area and, in particular, for biomedical applications because of their unique mechanical and physicochemical properties, such as their high thermal and electrical conductivity, biocompatibility, and large surface area. Graphene (G) and its derivatives represent the most common 2D nanomaterials applied to electrochemical (bio)sensors for healthcare applications. This review will pay particular attention to other 2D nanomaterials, such as transition metal dichalcogenides (TMDs), metal–organic frameworks (MOFs), covalent organic frameworks (COFs), and MXenes, applied to the electrochemical biomedical (bio)sensing area, considering the literature of the last five years (2018–2022). An overview of 2D nanostructures focusing on the synthetic approach, the integration with electrodic materials, including other nanomaterials, and with different biorecognition elements such as antibodies, nucleic acids, enzymes, and aptamers, will be provided. Next, significant examples of applications in the clinical field will be reported and discussed together with the role of nanomaterials, the type of (bio)sensor, and the adopted electrochemical technique. Finally, challenges related to future developments of these nanomaterials to design portable sensing systems will be shortly discussed.

Published: December 2023

To improve the adsorption efficiency of pollutants by biochar, preparing graphene-like biochar (GBC) or nitrogen-doped biochar are two commonly used methods. However, the difference in the nitrogen doping (N-doping) effects upon the adsorption of pollutants by pristine biochar (PBC) and GBC, as well as the underlying mechanisms, are still unclear. Take the tetracycline (TC) as an example, the present study analyzed the characteristics of the adsorption of TCs on biochars (PBC, GBC, N-PBC, N-GBC), and significant differences in the effects of N-doping on the adsorption of TCs by PBC and GBC were consistently observed at different solution properties. Specifically, N-doping had varied effects on the adsorption performance of PBC, whereas it uniformly improved the adsorption performance of GBC. To interpret the phenomenon, the N-doping upon the adsorption was revealed by the QSAR model, which indicated that the pore filling (VM) and the interactions between TCs with biochars (Ead-v) were found to be the most important two factors. Furthermore, the density functional theory (DFT) results demonstrated that N-doping slightly affects biochar’s chemical reactivity. The van der Waals (vdWs) and electrostatic interactions are the main forces for TCs-biochars interactions. Moreover, N-doping mostly strengthened the electrostatic interactions of TCs-biochars, but the vdWs interactions of most samples remained largely unaffected. Overall, the revealed mechanism of N-doping on TCs adsorption by biochars will enhance our knowledge of antibiotic pollution remediation.

Authors: Cho Homin , Jung Yunho , Lee Seongjoo
Published: December 2023

This paper addresses the challenge of enhancing range precision in radar sensors through supervised learning. However, when the range precision surpasses the range resolution, it leads to a rapid increase in the number of labels, resulting in elevated learning costs. The removal of background noise in indoor environments is also crucial. In response, this study proposes a methodology aiming to increase range precision while mitigating the issue of a growing number of labels in supervised learning. Neural networks learned for a specific section are reused to minimize learning costs and maximize computational efficiency. Formulas and experiments confirmed that identical fractional multiple patterns in the frequency domain can be applied to analyze patterns in other FFT bin positions (representing different target positions). In conclusion, the results suggest that neural networks trained with the same data can be repurposed, enabling efficient hardware implementation.

Published: December 2023

Wireless sensor networks (WSNs) have gained a positive popularity for structural health monitoring (SHM) applications. The underlying reason for using WSNs is the vast number of devices supporting wireless networks available these days. However, some of these devices are expensive. The main objective of this paper is to develop a cost-effective WSN based on low power consumption and long-range radios, which can perform real-time, real-scale acceleration data analyses. Since a detection system for vibration propagation is proposed in this paper, the synchronized monitoring of acceleration data is necessary. To meet this need, a Pulse Per Second (PPS) synchronization method is proposed with the help of GPS (Global Positioning System) receivers, representing an addition to the synchronization method based on real-time clock (RTC). As a result, RTC+PPS is the term used when referring to this method in this paper. In summary, the experiments presented in this research consist in performing specific and synchronized measurements on a full-scale steel I-beam. Finally, it is possible to perform measurements with a synchronization success of 100% in a total of 30 samples, thereby obtaining the propagation of vibrations in the structure under consideration by implementing the RTS+PPS method.

Published: December 2023

Nerve agents have recently been used in battlefield operations, espionage wars, and terrorist attacks. These compounds, like some pesticides, cause organophosphate poisoning. The rapid, noncontact detection of a sarin simulant in the liquid phase has been demonstrated at the Diagnostics and Metrology Laboratory of the Italian National Agency for New Technologies, Energy and Sustainable Economic Development using laser photoacoustic spectroscopy, an infrared absorption technology. The first measurements, carried out with an experimental system based on a quantum cascade laser and developed for the assessment of food authenticity in the “fingerprint region”, show that a detection limit of one nanolitre is within the reach of the instrument when chemometric analysis is applied.

Published: December 2023

Listening to music has been found to influence postural balance in both healthy participants and certain patients, whereas no study investigates such effects among healthy middle-aged women. Thus, this study aimed to investigate the effect of music on postural balance in middle-aged women. Twenty-six healthy women aged between 50 and 55 years participated in this study. A stabilometric platform was used to assess their postural balance by recording the mean center of pressure velocity (VmCOP) in the eyes-opened (OE) and -closed (EC) conditions on both firm and foam surfaces. Our results showed that listening to an excerpt of Mozart’s Jupiter significantly decreased the VmCOP values in two sensory conditions (firm surface/EO: (p < 0.01; 95% CI: 0.27 to 2.22); foam surface/EC: (p < 0.001; 95% CI: 0.48 to 2.44)), but not in the other two conditions (firm surface/EC and foam surface/EO). We concluded that listening to Mozart’s symphony improved postural performance in middle-aged women, even in challenged postural conditions. These enhancements could offer great potential for everyday functioning.
UAV-Assisted Cluster-Based Task Allocation for Mobile Crowdsensing in a Space–Air–Ground–Sea Integrated Network
Authors: Liu Yang , Li Yong , Cheng Wei , Wang Weiguang , Yang Junhua
Published: December 2023

Mobile crowdsensing (MCS), which is a grassroots sensing paradigm that utilizes the idea of crowdsourcing, has attracted the attention of academics. More and more researchers have devoted themselves to adopting MCS in space–air–ground–sea integrated networks (SAGSINs). Given the dynamics of the environmental conditions in SAGSINs and the uncertainty of the sensing capabilities of mobile people, the quality and coverage of the sensed data change periodically. To address this issue, we propose a novel UAV-assisted cluster-based task allocation (UCTA) algorithm for MCS in SAGSINs in a two-stage process. We first introduce the edge nodes and establish a three-layer hierarchical system with UAV-assistance, called “Platform–Edge Cluster–Participants”. Moreover, an edge-aided attribute-based cluster algorithm is designed, aiming at organizing tasks into clusters, which significantly diminishes both the communication overhead and computational complexity while enhancing the efficiency of task allocation. Subsequently, a greedy selection algorithm is proposed to select the final combination that performs the sensing task in each cluster. Extensive simulations are conducted comparing the developed algorithm with the other three benchmark algorithms, and the experimental results unequivocally endorse the superiority of our proposed UCTA algorithm.
mid-DeepLabv3+: A Novel Approach for Image Semantic Segmentation Applied to African Food Dietary Assessments
Authors: Baban A Erep Thierry Roland , Chaari Lotfi
Published: December 2023

Recent decades have witnessed the development of vision-based dietary assessment (VBDA) systems. These systems generally consist of three main stages: food image analysis, portion estimation, and nutrient derivation. The effectiveness of the initial step is highly dependent on the use of accurate segmentation and image recognition models and the availability of high-quality training datasets. Food image segmentation still faces various challenges, and most existing research focuses mainly on Asian and Western food images. For this reason, this study is based on food images from sub-Saharan Africa, which pose their own problems, such as inter-class similarity and dishes with mixed-class food. This work focuses on the first stage of VBDAs, where we introduce two notable contributions. Firstly, we propose mid-DeepLabv3+, an enhanced food image segmentation model based on DeepLabv3+ with a ResNet50 backbone. Our approach involves adding a middle layer in the decoder path and SimAM after each extracted backbone feature layer. Secondly, we present CamerFood10, the first food image dataset specifically designed for sub-Saharan African food segmentation. It includes 10 classes of the most consumed food items in Cameroon. On our dataset, mid-DeepLabv3+ outperforms benchmark convolutional neural network models for semantic image segmentation, with an mIoU (mean Intersection over Union) of 65.20%, representing a +10.74% improvement over DeepLabv3+ with the same backbone.

Published: December 2023

With the continuous development of electric vehicle (EV) technology, there is an increasing need to analyze the factors influencing customers’ purchase intentions. According to the data of customers’ vehicle experience evaluation and personal information, this paper develops the analysis models of influencing factors using the analysis of variance algorithm (ANOVA) and Kruskal–Wallis algorithm. Then, the purchase intention model for EVs is proposed using the random forest method. Finally, the optimization model for the EV sales plan was built. The results show that the main factors influencing customers’ purchases are different for different vehicle brands. However, the customer’s evaluation of the vehicle experience has a greater influence on the customer’s purchase. Compared to other prediction models, the random forest model has the highest accuracy. For 3 EV brands, the prediction accuracies are 97.8%, 98.9%, and 97.6%. In addition, this paper predicts the purchase intentions of 15 customers. By optimizing the sales plans for 3 EV brands, the predicted purchase rate of 15 customers increased from 40% to 53%. The research work contributes to the sales of electric vehicles, the accurate positioning of customers, and the identification of more potential customers.

Book Review: "When Religion Hurts You" by Laura E. Anderson
Authors: Vaughn Marsha
Published: December 2023

Licensed psychotherapist, podcast host, and religious trauma survivor, Dr. Laura Anderson, has contributed a volume drawing from both her own experiences and trauma studies scholarship. Anderson avoids harsh and direct condemnation of high-control religions (HCRs) but, rather, describes the human experiences and biological explanations of lives immersed in fear, shame, and mistrust. Her book, When Religion Hurts You, will likely connect most with religious trauma survivors who have already left an HCR (or are on the way out) and with professionals unfamiliar with the specific biological and relational theories of trauma. Anderson provides cautious optimism, noting the time and effort needed to “live in healing bodies.”

Исследован спектр жирных кислот (ЖК) молока (245 образцов) коров генофондной красной горбатовской породы. В структуре компонентов жирнокислотного состава молока преобладали насыщенные ЖК — до 62% (С16:0 — 0,794 г/100 г молока). В группе мононенасыщенных ЖК обнаружено высокое содержание олеиновой (С18:1) ЖК — 1,126 г/100 г молока. В зависимости от длины углеродной цепи в весенне-летний период в молоке коров преобладают средне- и длинноцепочечные ЖК — 1,165 и 1,433 г/100 г молока соответственно. Доля трансизомеров жирных кислот в молоке составила почти 2% (Сv — 90%). Между собой жирные кислоты, независимо от насыщенности и длины цепи, имеют положительную корреляцию более 0,7. Выявлены общие кластеры на BTA 9 и 22 — для пальмитиновой и миристиновой ЖК; на BTA 20 — для пальмитиновой, миристиновой и олеиновой ЖК; на BTA 25 — для пальмитиновой, миристиновой, стеариновой и олеиновой ЖК.

Published: December 2023

Petani mengalokasikan waktu untuk empat aktivitas, yaitu aktivitas produktif, domestik, pribadidan menikmati waktu luang. Penelitian dilakukan dengan metode survei di Desa Tegalgiri, KecamatanNogosari, Kabupaten Boyolali pada bulan November 2020–Februari 2021. Penelitian bertujuan untukmengetahui karakteristik petani dan rumah tangga petani, distribusi penggunaan waktu dan faktor-faktor yang memengaruhi waktu luang petani. Data dianalisis deskriptif menggunakan nilai rerata dan regresi linear berganda. Hasil analisis menunjukkan bahwa aset lahan sawah tadah hujan rata-rata petani hanya 0,23 ha, dengan waktu yang digunakan untuk kegiatan produktif sebesar 7,43 jam per hari (30,96 persen). Berdasarkan persentase, waktu untuk kegiatan produktif lebih besar daripada kegiatan non produktif (rumah tangga+pribadi+mengisi waktu luang). Besar kecilnya waktu luang petani dipengaruhi oleh jumlah anggota keluarga, pendapatan dan produksi padi. Ketiga faktor tersebut berpengaruh nyata dan positif, sementara jumlah anggota keluarga berpengaruh nyata dan negatif. Karena itu peningkatan waktu luang dapat dilakukan dengan meningkatkan pendapatan rumah tangga petani melalui peningkatan produksi maupun peningkatan kapabilitas sumber daya pertanian lahan sawah tadah hujan dengan melakukan bimbingan dan pendampingan penerapan inovasi teknologi.

Authors: Astawan Made
Published: December 2023

A typical Indonesian food, tempe, is made by fermenting soybeans by the mold Rhizopus spp. Oneeffort to develop products and diversify food is to use tempe as the main ingredient in making tempe drink powder (TDP). Processing tempe into drink powder will increase tempe consumption and meet people’s protein needs. Over time, the quality of food products will decrease. Therefore, to ensure that the product remains fit for consumption, it is essential to know about changes in its physicochemical and microbiological properties. This research aimed to determine changes in physicochemical and microbiological properties of TDP products during storage at various temperatures. The physicochemical characteristics tested were proximate value, aw, pH, antioxidant activity, and whiteness. Microbiological characteristics included total mold and total plate count. The water content value increased at storage temperatures of 35 °C and 45 °C, but tended to decrease at 55 °C. During storage, the protein and fat content tended to be stable. Antioxidant activity increased at 25, 35, and 45 °C and decreased at 55 °C. Ash content, aw, pH, whiteness, and total plate decreased at each storage temperature.

Published: December 2023

The application of tourism health, such as food safety, is an important matter to pay attention to. Based on the annual report (BPOM, 2019), there are 373 cases of food poisoning in Bali, so Bali ranks fourth with the highest cases of food poisoning in Indonesia. The type of research used is observational. This research was conducted by testing samples to determine microbial contamination on pork satay as well as observing and recording food safety scores where pork satay is sold. The design used was cross-sectional because all research subjects were observed at one time. Food safety scores were tested, and TPC, MPN, and E. coli were tested so that 9 samples (56.25%) were categorized as vulnerable to safe consumption. 16 samples of pork satay met the minimum requirements for microbial contamination, ranging from 20/g to 60,000/g. 1 sample of pork satay (6.25%) with the amount of coliform contamination exceeding the standard, namely 438/gr. There were 6 samples of pork satay (37.5%) positive for E. coli. Based on the results of the Kruskal-Wallis test for total microbial contamination based on the food safety score, the results showed that there was a difference in the results of the microbial contamination test and E. coli with a food safety score. Coliform bacteria contamination based on the food safety score showed that there was no difference from the results of the MPN test with the food safety score based on the Asymp.sig value 0.05. Even so, there are still many traders who have not implemented personal hygiene, so it is necessary to carry out food safety training, monitoring, and developing food quality on a regular basis.

La violencia bestial y sub-humana de los griegos en la Alejandra de Licofrón
Authors: Crossio Rizzi Melina
Published: December 2023

El uso de metáforas animales en la Alejandra de Licofrón ha sido objeto de estudio de varios críticos. En este artículo se analizará la construcción de la figura de los griegos a partir de su animalización. Este proceso incluye tanto el uso de metáforas y comparaciones animales, como el léxico utilizado en la descripción de estados y acciones de los personajes. En este sentido, se desplegará la asimilación de los griegos a los animales y, por lo tanto, su degradación a criaturas barbáricas y sub-humanas.

Articulaciones del poder y la cultura en la Ferrara “teatral” de los Este (siglos XV y XVI).
Authors: Sforza Nora
Published: December 2023

A mediados del siglo XV, la ciudad de Ferrara brillaba en la península italiana como un importante centro de estudios, al cual accedían no solo aspirantes de ciudades vecinas, sino también de otras regiones de Europa, allende los Alpes. En efecto, la transformación de la ciudad de sede del poder de una familia feudal a centro de producción y de irradiación de cultura humanista se verificará justamente en estos años (Tateo, 2004, p.16), gracias también al constante apoyo financiero de la corte estense. En este sentido, uno de los mayores exponentes del florecimiento cultural ferrarés fue, sin duda, Ludovico Ariosto (Reggio Emilia, 1474 - Ferrara, 1533), familiar de la familia de los Este y uno de los más grandes poetas de la tradición occidental. El objetivo del presente artículo es observar las implicancias de la obra dramática del autor del Orlando furioso en el contexto de la política cultural trazada por la familia Estense en los albores de la Modernidad clásica, mostrando aspectos de su producción dramática donde es posible detectar las tensiones existentes con el poder político ferrarés. En un ámbito diferente del de la mera lectura, Ariosto propondrá textos escénicos desde donde podrá crear un nuevo espacio para la crítica a ciertos aspectos de la cultura oficial a la cual, sin embargo, él mismo pertenecía.
