Published: April 2023

The mechanical stresses in the thin-walled quasi-force-free winding of the solenoid, which arise when a strong pulsed magnetic field is produced, can be significantly reduced if the winding is inserted into the area between two magnets creating crossed fields. It is shown that with a rational choice of the amplitude and shape of the external fields pulses the stresses can be reduced to values less than one tenth of the magnetic pressure of the generated field.
Artificial Intelligence Applications for Assessment, Monitoring, and Management of Parkinson Disease Symptoms: Protocol for a Systematic Review
Authors: Bounsall Katie , Milne-Ives Madison , Hall Andrew , Carroll Camille , Meinert Edward
Published: April 2023

Background

Parkinson disease (PD) is the second most prevalent neurodegenerative disease, with around 10 million people with PD worldwide. Current assessments of PD symptoms are conducted by questionnaires and clinician assessments and have many limitations, including unreliable reporting of symptoms, little autonomy for patients over their disease management, and standard clinical review intervals regardless of disease status or clinical need. To address these limitations, digital technologies including wearable sensors, smartphone apps, and artificial intelligence (AI) methods have been implemented for this population. Many reviews have explored the use of AI in the diagnosis of PD and management of specific symptoms; however, there is limited research on the application of AI to the monitoring and management of the range of PD symptoms. A comprehensive review of the application of AI methods is necessary to address the gap of high-quality reviews and highlight the developments of the use of AI within PD care.

Objective

The purpose of this protocol is to guide a systematic review to identify and summarize the current applications of AI applied to the assessment, monitoring, and management of PD symptoms.

Methods

This review protocol was structured using the PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols) and the Population, Intervention, Comparator, Outcome, and Study (PICOS) frameworks. The following 5 databases will be systematically searched: PubMed, IEEE Xplore, Institute for Scientific Information’s Web of Science, Scopus, and the Cochrane Library. Title and abstract screening, full-text review, and data extraction will be conducted by 2 independent reviewers. Data will be extracted into a predetermined form, and any disagreements in screening or extraction will be discussed. Risk of bias will be assessed using the Cochrane Collaboration Risk of Bias 2 tool for randomized trials and the Mixed Methods Appraisal Tool for nonrandomized trials.

Results

As of April 2023, this systematic review has not yet been started. It is expected to begin in May 2023, with the aim to complete by September 2023.

Conclusions

The systematic review subsequently conducted as a product of this protocol will provide an overview of the AI methods being used for the assessment, monitoring, and management of PD symptoms. This will identify areas for further research in which AI methods can be applied to the assessment or management of PD symptoms and could support the future implementation of AI-based tools for the effective management of PD.

Four Lessons Learned From Career Pivots in Academic Medicine (Preprint)
Authors: Allen Jay-Sheree , Oxentenko Amy
Published: April 2023

UNSTRUCTURED

Women in the fields of medicine and science often consider career pivots to transition out or transition up; in this review, we offer 4 lessons learned to make those pivots maximally successful. These lessons emphasize the need to honor the feeling that it is time to pivot, especially if you develop a strong sense of restlessness indicating you are in a space that no longer serves you; they also emphasize the importance of seeking the guidance of a mentor, sponsor, or coach. Although flexibility is a substantial part of the transition, it is important to have a road map in the form of a career development plan, and it is of utmost importance to complete the transition professionally.

Published: April 2023

Mental health influences people’s productivity from individual-level to enterprise level. This important factor should be assessed and tackled by the primary care unit since healthy community is their ultimate goal. Sixty of two screening tools (self-rating questionnaire [SRQ20] and patient health questionnaire [PHQ9]) were randomly distributed by primary care unit through cadres at Kricak, Tegalrejo District to community which is attending the cadre launching. SRQ had an 83,33% response rate, whereas PHQ9 has only 41,7% response rate. By comparative distributive analysis, it was found that one person who fallen into moderately severe symptoms of depression in PHQ9 was had not fallen into the person who has mental problem based on SRQ20, and two persons who fall into the moderate symptom of depression in PHQ9 were had not fallen into person who has mental problem based on SRQ20. There was 20% inconsistency between the two tools of mental health assessment. Using two tools assessing mental health problem is fruitful since it will cover each other. This study proved that there could be divergent result from both questionnaires. A decision before continuity management care of depression should be taken carefully. There should be another step taken by primary care unit before they undergo management care for depression.

Authors: Wijayadi Linda Julianti , Kelvin Kelvin
Published: April 2023

Melasma, known as a hyperpigmentation disorder, is more common in women of childbearing age with Fitzpatrick IV-VI skin types. Various factors of this disease, namely genetic factors, UV exposure, hormonal, thyroid disease, pregnancy, and drugs. The best treatment for melasma is with 2 – 4% hydroquinone, but because of the side effects, alternative treatments are mostly used for melasma. One of them is with essential oils. Essential oils have been investigated as depigmenting agents because of their anti-tyrosinase potential. In this literature, it is proven that the essential oils of sage (Salvia), hedgenettle / woundwort (Stachys), lavender (Lavandula), tea tree (Melaleuca alternifolia), cinnamon (Cinnamomum), mountain tea (Sideritis), pomelo (Citrus grandis ( L) Osbeck), and kaffir lime (Citrus hystrix DC) are effective against melasma. The purpose of this literature is to discuss the various effects of essential oils that can be used as depigmentation agents in the alternative treatment of melasma.

Among these Paenibacillus alvei showed the highest cellulase activity.
Conclusion: The findings of this study could pave the way for the use of cellulose as an inexpensive energy source for bacteria that are capable of producing valuable products.
Energy Management For Renewable Hybrid System Based On Artificial Neural Networks (ANN)
Authors: Babu M. Nagendra
Published: April 2023

Abstract: It has become necessary in recent years to use renewable energy sources, such as wind and solar energy, to meet the load demand. Because of their endless existence and environmentally friendly nature, they are useful for power generation. The management of energy in hybrid wind-solar power sources is the topic of this article. Using a common current source interface multiple-input DC-DC converter, the photovoltaic (PV) array, wind turbine, and battery storage are all connected. The power control between intermittent renewable energy generation, energy storage, and the grid is maintained by the artificial neural network (ANN) controller. For wind turbines to produce the most electricity, variable speed control can be used. For solar systems, the Maximum Power Point Tracking (MPPT) algorithm is used. By keeping the common DC voltage constant, the grid interface inverter sends the energy drawn from the PV array and wind turbine into the grid. Using MATLAB Simulink, the complete control strategy is subjected to a simulation study. The results of the simulation show the photovoltaic/wind hybrid system's dynamic behavior and control effectiveness

EFISIENSI RELATIF PEMUPUKAN METODE BENAM (POCKET) TERHADAP METODE TEBAR (BROADCAST) DI PERKEBUNAN KELAPA SAWIT
Authors: Ginting Eko Noviandi , Rahutomo Suroso , Sutarta Edy Sigit
Published: April 2023

Metode tebar (broadcast) dan metode benam (pocket) merupakan metode pemupukan yang umum digunakan di perkebunan kelapa sawit. Terdapat perbedaan pendapat di kalangan pekebun sawit mengenai metode yang lebih baik di antara kedua metode tersebut untuk diterapkan pada skala luas.  Sebagian pekebun lebih memilih metode benam dengan alasan untuk meminimalisir kehilangan pupuk melalui runoff dan penguapan. Di sisi lain, sebagian pekebun memilih metode tebar dengan alasan pupuk lebih terdistribusi merata di bidang cakupan akar sehingga serapan hara oleh tanaman lebih maksimal. Untuk mengkaji kedua pendapat tersebut telah dilakukan telaah terhadap penelitian-penelitian terdahulu guna menggali data besarnya kehilangan hara dari masing-masing metode pemupukan. Hasil telaah tersebut digunakan sebagai dasar untuk menghitung nilai efisiensi relatif pemupukan pada kedua metode. Hasil penghitungan menunjukkan bahwa efisiensi relatif aplikasi pupuk menggunakan metode benam terhadap metode tebar untuk hara N, P, K, dan Mg berturut-turut adalah sebesar 10,16%; 0,29%; 6,71%; dan 4,83%. Hal tersebut berarti jumlah hara N, P, K, dan Mg yang hilang dari pupuk yang diaplikasikan pada metode benam lebih kecil sekitar 22% dibanding hara yang hilang jika pemupukan dilakukan dengan metode tebar. Selanjutnya hasil simulasi menunjukkan bahwa biaya pemupukan menggunakan metode benam lebih rendah sekitar 10% dibanding biaya aplikasi pupuk metode tebar. Semakin tinggi potensi kehilangan hara, maka semakin efektif aplikasi pemupukan secara benam.

Authors: Rizki Ilmi Fadhilah
Published: April 2023

Penggunaan pelarut organik saat ini telah menjadi salah satu masalah dalam pengembangan teknologi industri karena cenderung beracun, merusak lingkungan, dan juga menggunakan biaya produksi yang tinggi. Pelarut tersebut masih digunakan pada industri farmasi dan pangan, namun jika dikonsumsi diatas batas maksimal konsentrasinya akan memberikan pengaruh terhadap kesehatan manusia. Pelarut organik biasanya digunakan untuk mengeksktrak fitonutrien yang terdapat pada tanaman. Minyak kelapa sawit merupakan salah satu minyak nabati yang kaya akan berbagai fitonutrien yang dapat dikembangkan menjadi sebuah produk pangan, farmasi, dan kosmetik. Berdasarkan hal tersebut, pengembangan teknologi ramah lingkungan (green technology) sangat dibutuhkan untuk dapat meminimalkan pemakaian pelarut organik. Teknologi ramah lingkungan ini akan menerapkan penggunaan minimum pelarut yang berbahaya dengan mengembangkan pelarut yang ramah lingkungan (green solvent). Natural Deep Eutectic Solvent (NaDES) akan menjadi alternatif pengganti pelarut organik umum tersebut. NaDES tersusun dari komponen senyawa metabolit primer yang terdapat pada makhluk hidup, sehingga memiliki sifat yang mudah terurai, tidak beracun, tidak mudah menguap, aman dan murah untuk menghasilkan pelarut ramah lingkungan yang dapat digunakan pada industri pangan dan farmasi. Potensial yang dimiliki oleh NaDES ini akan terus dikembangkan dan digunakan untuk mengekstraksi fitonutrien yang terdapat pada minyak kelapa sawit dengan efektif dan selektif.

Normativism of Islamic Law in the Akkattere Hajj Ritual of South Sulawesi’s Ammatoa Community
Authors: Misbahuddin Misbahuddin , Ys Arba'iyah , Cahyani Andi Intan , Samsudin Titin , Fuad Iwan Zainul
Published: April 2023

The profound impact of cultural and religious modernity on various aspects of life has brought about significant changes in regional akkattere traditions in Ammatoa society. According to this hadith, the pilgrimage which is in harmony, the conditions and obligations are in accordance with Islamic law, and which must be performed at a certain time and place, can be completed easily through the akkattere ritual. This research is an empirical law using an anthropological approach to Islamic law. The purpose of this study is to examine the incorporation of customary values and Islamic law in the Akkattere tradition of the Ammatoa community in the region, and to evaluate its impact. Data was collected using interviews and literature studies. The research was conducted in Tanah Towa Village in Kajang District, Bulukumba Regency, South Sulawesi Province. The research concluded that the akkatere ritual obviated the need to wait in long lines or have the financial resources to perform the pilgrimage to the holy land of Mecca. Based on the findings of this study, anthropologically the akkattere traditional law is the result of a dialectic between Islam and local traditions and has resulted in new local pilgrimage practices, which is now a religious characteristic of the Ammatoa people. Nonetheless, the understanding of Hajj by the Ammatoa community has deviated substantially from the normatism of Islamic law, so that it fundamentally influences aspects of religious belief and ideology.
A koronavírus-járvány ábrázolása az amerikai kórházsorozatokban

A tanulmány témája a 2020–2022 között futó öt, főműsoridőben sugárzott amerikai kórházsorozat (A Grace klinika, A rezidens, Chicago Med, Doktor Murphy, New Amsterdam) koronavírus-járvány ábrázolása. A kórházsorozat-elemzések gyakori kerete a kultivációs elmélet; több kutatás vizsgálta már a műfaj edukációs értékét is. Ezekhez az irányvonalakhoz kapcsolódva, az elemzés célja a visszatérő történetelemek, narratívák azonosítása – kiemelt szempont a technológia, az információáramlás és a szakértők ábrázolása. A sorozatok három idősíkra tagolták a pandémia bemutatását: a fertőzöttek megjelenése; az első hullám alatt kialakuló krízis; a hullám lecsengését követő időszak. Elmondható, hogy kiálltak a járvánnyal kapcsolatos tudományos álláspontok és a biztonsági protokollok betartása mellett. A pandémia új klasszifikációs kategóriát hozott létre a műfajban: 2020 óta a kórházsorozatok az alapján is megkülönböztethetőek, hogy létező vagy lezárt problémaként ábrázolják a koronavírus-járványt. Ez a kérdés különösen fontos ennél a műfajnál, hiszen a kezdetektől fogva törekszik a hiteles információk átadására, valamint a nézők edukációjára.
Thermoregulatory strategies of songbird nestlings reveal limited capacity for cooling and high risk of dehydration
Authors: Diehl Jenna , Alton Lesley , White Craig , Peters Anne
Published: April 2023

Developing young are particularly sensitive to environmental challenges,
often with life-long consequences, but the risks of climate warming
during this period are not well understood. To quantify the
physiological effects of increasing temperatures for developing
endotherms, we measured metabolic rate, water loss, and heat dissipation
behaviours between 25-45°C in nestlings of a free-living songbird. The
thermoneutral zone ranged from 33.1–42.3°C – higher and narrower than
adults – and metabolic rate increased sharply above and below this
range. Water loss was constant below 33.5°C, above which it increased
sharply, when nestlings also drooped their wings to lose heat. Despite
nestlings initiating panting (p50) around 40°C, water loss was never
sufficient to dissipate metabolically produced heat, indicating poor
cooling capabilities. Our data show that while developing young appear
relatively tolerant to higher temperatures, they are at a high risk of
dehydration and hyperthermia, with limited ability to mitigate these
risks of increasing temperatures.
Primary Frequency Regulation for Multi-Infeed HVDC System Using Model Predictive Control and Local Estimation
Authors: Tian Guoliang , Du Zhengchun , Li Yujun
Published: April 2023

This paper proposes a novel primary frequency regulation (PFR) scheme
for Multi infeed HVDC (MIDC) system. First, a dynamic model for
frequency response (FR) in MIDC system is carried out to involve
LCC-HVDCs in frequency regulation. Then, a disturbance observer (DO) is
proposed to estimate both the power imbalance and the full order states
of the system. By combining a Kalman filter (KF), this DO gets an
accurate estimation quickly with local frequency measurement. On the
basis of the estimated disturbance and state variables, feedforward
control schemes can be concluded to fully utilize the fast adjustability
of LCC-HVDCs. In this paper, an model predictive control (MPC) based
scheme is designed to coordinate LCC-HVDCs under constraints of HVDC
capacity and frequency boundaries. As a result, the optimal
power-sharing property of LCC-HVDCs is achieved to enhance the PFR
dynamic performance of the AC main system. Further, the stability of the
proposed method is analyzed using Lyapunov method. Finally, numerical
simulations are concluded to verify the effectiveness and the merits of
the proposed method, by comparing it to typical droop controls.
An analytic model for Tropical cyclone outer winds
Authors: Cronin Timothy Wallace
Published: April 2023

The variation of Tropical cyclone azimuthal wind speed (V) with distance
from storm center (r) is a fundamental aspect of storm structure that
has important implications for risk and damages. The theoretical model
of Emanuel (2004), which applies well outside the rainy core of the
storm, matches radiatively-driven subsidence and Ekman suction rates at
the top of the boundary layer to obtain a nonlinear differential
equation for dV/dr. This model is particularly appealing because of its
strong physical foundation, but has no known analytic solution for V(r).
In this paper, I obtain an analytic solution to V(r) for the Emanuel
(2004) outer wind model. Following previous work, I then use this
solution to explore properties of merged wind models that combine the
outer model with an inner model that applies to the rainy core of a
storm.
Assessment of Relative Risk of Seawater Intrusion Mechanisms in the Coastal Plains of the Limpopo River Basin, Mozambique
Authors: Zuccolotto Gabriella , Kahler David Murray
Published: April 2023

Seawater inundation was reported in the Limpopo River near the mouth at
Xai-Xai, Mozambique. Local authorities identified a decrease in river
flow as the cause of seawater inundation. We examined the potential of
land subsidence in the relative risk of seawater inundation. Land
subsidence has been identified as a risk to urban centers; however, we
focused on the risk to the surrounding agricultural region. We used
Sentinel-1 interferometric synthetic aperture radar (InSAR) with small
baseline subset (SBAS) method to determine the rate of land subsidence
throughout the agricultural-rich river valley surrounding Xai-Xai,
Mozambique. InSAR presents a useful tool to assess land deformation;
however, the signal decorrelated in the wet season, which limited our
analysis to the dry season. Land subsidence may be due to groundwater
abstraction, erosion without sediment transport and replenishment or
other alteration of the surface, or tectonic movement. We estimated that
the coastal region, which is largely agricultural, has subsided at an
average rate of 13 mm/a from 2017 to 2022 and as much as 30 mm/a. This
suggests that land subsidence contributes to the relative risk of
seawater inundation on the same scale as the decrease in river
discharge. Seawater inundation presents a threat to economic growth and
food security in the region.
Financing Climate-Friendly Cooling at City Scale
Authors: Shen Bo , Zhou Yun , Zhou Jie
Published: April 2023

This paper explores how greener refrigeration and air-conditioning could be provided at city scale. Refrigeration and air-conditioning are major contributors to climate change, and demand for them is growing. Crucial obstacles to climate-friendly cooling solutions in developing countries in Asia are the lack of accessible and affordable financing and insufficient project scale. This paper discusses a variety of financing instruments and business models and presents an integrated model for financing city-scale green cooling. The model could help roll out green cooling solutions at a scale large enough to attract investors and to reduce transaction costs through standardized implementation.

The zeroth-order general Randic index, 0R?(G), of a connected graph G, is
defined as 0 P R?(G) = ni =1 d?i , where di is the degree of the vertex vi
of G and ? arbitrary real number. We consider linear combinations of the
0R?(G) of the form 0R?(G) ? (? + ?)0R??1(G) + ?? 0R??2(G) and 0R?(G) ? 2a
0R??1(G) + a2 0R??2(G), where a is an arbitrary real number, and determine
their bounds. As corollaries, various upper and lower bounds of 0R?(G) and
indices that represent some special cases of 0R?(G) are obtained.
On strategies for selection games related to countable dimension
Authors: Caruvana Christopher , Clontz Steven
Published: April 2023

Two selection games from the literature, Gc(O,O) and G1(Ozd,O), are known to
characterize countable dimension among certain spaces. This paper studies
their perfect- and limited-information strategies, and investigates issues
related to non-equivalent characterizations of zero-dimensionality for
spaces that are not both separable and metrizable. To relate results on
zero-dimensional and finite-dimensional spaces, a generalization of
Telg?rsky?s proof that the point-open and finite-open games are equivalent
is demonstrated.

Introduction. Ectopic cervical thymus (ECT) occurs as a result of incomplete migration of the thymic primordia during embryogenesis. In the majority of cases, ECT is asymptomatic; however, in 10% of patients, there are different kinds of symptoms. Case report. A four-month-old baby boy was referred to our clinic for an evaluation of a growing large mass on the right side of the neck, present since birth. Physical examination revealed a solid, painless, soft, moderately mobile mass of irregular round shape localized on the right side of the neck, in front of the sternocleidomastoid muscle, below the parotid gland, and above the carotid lodge. The skin above the mass was unchanged. The dimensions of the mass were 40 ? 32 ? 15 mm. Based on the clinical and ultrasonographic findings, as well as the findings of the magnetic resonance imaging, it was suspected that the mass was an ECT. The mass was removed by surgical excision. The pathohistology report confirmed the presence of an ECT, with Hassall?s corpuscles in the medulla. The postoperative course went smoothly, and the wound healed well. During the regular clinical, immunological, and ultrasound follow-ups over a period of six months, normal findings were registered. Conclusion. Congenital ECT is a rare congenital anomaly that must be, however, taken into account when considering the differential diagnosis of cervical tumor masses.

Published: April 2023

We examine whether auditors helped public clients obtain U.S. Paycheck Protection Program (PPP) loans to overcome the COVID-19-related economic crisis. Larger auditors had better access to resources to help their auditees with PPP applications. However, the Big 4 auditors were primarily focused on helping large banks process PPP loans, which constrained their ability to help their auditees. We predict and find that auditees of Second-Tier auditors are more likely than auditees of Big 4 auditors to obtain a PPP loan. In contrast to the Big 4 and Second-Tier auditors, many Small auditors faced significant financial challenges during the pandemic and had to avail of PPP loans. We find that auditees of Small auditors who availed (did not avail) of PPP loans were less (as) likely to obtain PPP loans than (as) auditees of Second-Tier auditors. Our findings demonstrate the value that non–Big 4 auditors can provide through nonaudit services.

Photosensitizing properties of hydrochlorothiazide may increase skin cancer risk. To date, study findings on the association between hydrochlorothiazide use and skin cancer risk are inconsistent, notably regarding confounding and dose-response. The aim of this study was to investigate the association between hydrochlorothiazide use and incidence of skin cancer in a cohort of unselected Caucasian adults, taking dosing into account. As part of the PharmLines Initiative, which links data from the Lifelines Cohort Study and prescription database IADB.nl, patients aged ≥ 40 years were included from Lifelines, a prospective population-based cohort study in the north of the Netherlands. Skin cancer incidence was compared between subjects starting hydrochlorothiazide treatment (n = 608), subjects starting treatment with other antihypertensives (n = 508), and non-antihypertensive long-term medication users (n = 1,710). Cox regression analyses were performed to obtain hazard ratios, adjusted for potential confounders. The risk of any skin cancer, keratinocyte carcinoma, basal cell carcinoma and squamous cell carcinoma was not significantly increased in general hydrochlorothiazide users. A clear association was observed between high cumulative hydrochlorothiazide use (≥ 5,000 defined daily dose; ≥ 125,000 mg) and the risk of any skin cancer (adjusted hazard ratio 5.32, 95% confidence interval (95% CI) 2.40–11.81), keratinocyte carcinoma (adjusted hazard ratio 7.31, 95% CI 3.12–17.13), basal cell carcinoma (adjusted hazard ratio 7.72, 95% CI 3.11–19.16) and squamous cell carcinoma (adjusted hazard ratio 19.63, 95% CI 3.12–123.56). These findings should lead to awareness with high use of hydrochlorothiazide in Caucasian adults.

Proposed Strategy to Improve Profitability at PT. Kurita Indonesia
Authors: Kahfi Azhari
Published: April 2023

During its operation in Indonesia, PT. Kurita Indonesia as a water treatment company has recorded considerably low profitability and the revenue growth has not been optimal based on year-on-year comparison. Some of the factors that cause the problems are the increasingly tight price competition and the high prices of raw materials for commodity products. To achieve better profitability and gain more market share, research was conducted to understand the market of water treatment in Indonesia, to identify what is needed by its customers and be able to differentiate the company from its competitors, thus the company can determine its competitive advantage and implement it for a new strategy. The research was conducted by qualitative method with data were collected from interview with respondents and direct observation to the internal company and its customers. The result of research shows that water treatment customers in industries tend to choose water treatment supplier who can provide added value to their companies, especially from environmental standpoint and cost saving of the total operating cost. Hence, PT. Kurita Indonesia should create a strategy that focuses on value creation to customers and utilize its unique products that can be relied upon to provide value to customers. The company should also implement a value-focused marketing strategy to adapt and respond to future challenges.
The impacts of innovative and competitive abilities of SMEs on their different financial risk concerns: System approach
Authors: Civelek Mehmet , Krajčík Vladimír , Fialova Vendula
Published: April 2023

Research background: The lack of financial resources of small and medium enterprises (SMEs) make them face high financial risk. Their entrepreneurial abilities that belong to Resource-based View (RBV), such as innovativeness and competitiveness, might reduce SMEs? financial risk because those entrepreneurial abilities increase the financial performance of businesses.
Purpose of the article: This paper aims to investigate the effects of the innovativeness and competitiveness of SMEs on their financial concerns based on financial risk, including bankruptcy, financial performance, and financial risk management.
Methods: The authors use a method of data analysis and synthesis, including advanced knowledge and digital processing of background studies. This paper examines 1221 SMEs from the Czech Republic, Slovakia, and Hungary. Those firms are chosen by random sampling method from Cribis and the Budapest Chamber of Commerce databases. Then the researchers directed an online questionnaire to collect the research data from the randomly selected firms. The researchers use Ordinal Logistic Regression Test for analysis purposes.
Findings & value added: This paper's results indicate that SMEs' competitiveness does not impact SMEs? bankruptcy prediction, financial performance, or financial risk management. On the other hand, while more innovative SMEs are less likely to face bankruptcy issues than less innovative SMEs, less innovative SMEs indicate better financial performance than their more innovative counterparts. Since this paper focuses on the influences of intangible assets of SMEs (such as characteristics based on RBV and Entrepreneurial Orientation) on their tangible assets (financial performance etc.) and puts emphasis on this fact from an International perspective, this paper makes a significant contribution to the literature. Furthermore, analyzing multiple relationships between SMEs? different entrepreneurial characteristics and various financial risk concerns is another important fact that might draw prospective readers? attention.
First Crystal Structures of alpha,delta-Peptidic Foldamers and Solution State NMR Show an Unusual 13/11 Helix: Rational Design and Application as a Minimalist Aldolase Mimic

Published: April 2023

We report the first structures of an unusual 13/11-helix (alternating i,i+1 {NH--O=C} and i,i+3 {C=O--H—N} H-bonds) formed by a heteromeric 1:1 se-quence of alpha- and delta-amino acids, using both XRD and NMR. Whilst intramolecular hydrogen bonds (IMHBs) are the clear driver of helix formation, we also observe an apolar interaction between the ethyl residue of one delta-amino acid and the cyclohexyl group of the next delta-residue in the sequence that seems to stabilize one type of helix over another. Using this structural information, we have inserted two ornithine residues within the helix to install bis-amine functionality. The resulting foldamer acts as a minimalistic aldolase mimic.

preservation process with chitosan-based coating with tannin and vinegar
Authors: Loi N.V. , Binh P.T. , Sam V.K.
Published: April 2023

The objective of this study was to determine the change in physicochemical and
biochemical parameters of Phuc Trach pomelo during preservation by coating. From
there, it forms the basis for building a preservation process. Preservative coating
preparations are formed by mixing ingredients according to the ratio: 1.92% chitosan,
0.24% tannin, 1.92% vinegar, and 95.92% water. One kg of this preparation will be
enough to cover about 19 kg of pomelo. Set up four experimental formulas to preserve
Phuc Trach pomelo: CT1: preserved in the natural environment, no preservative coating is
used, the content of coating-forming preparations is 0%; CT2, CT3, CT4 used coatingforming preparations with the content of 1.0%, 1.5% and 2.0%, respectively. The results
showed that Phuc Trach pomelo preserved in formula CT3 with the composition of 1.5%
was effective in limiting the change of physico-chemical and biochemical indicators more
effectively than other experimental formulas. After 7 weeks of storage, the colour changed
from 0.96 to 8.16, hardness changed from 15.16 to 10.23 (kg/cm2
); respiratory intensity
from 35.68 to 18.95 (mL CO2/kg.h); soluble solids content from 10.04 to 11.46oBx; total
sugar content from 8.99 to 5.06%; vitamin C content from 0.84 to 0.42mg/g; total protein
content from 0.79 to 0.38%; total organic acid content from 0.62 to 0.17%. Meanwhile,
Phuc Trach pomelos preserved in other recipes until the 5th and 6th week were completely
rotten. Therefore, the formula CT3 was selected with a preservative composition of 1.5%
to develop the process of preserving Phuc Trach pomelo.
Information Technology Factors Impacting Educators before and during COVID-19: A Study of Developing Countries
Authors: Keevy Monique
Published: April 2023

Purpose: The purpose of the paper is to explore the negative impact of information technology (IT) factors prior to and during COVID-19 from the perspectives of developing country educators, to obtain context to the higher education environment to aid future teaching practices.

Design/methodology/approach: The study employs a mixed method approach comprising a questionnaire and interviews with educators situated in two African developing countries from the South African Development Community (SADC).

Findings: This paper found that the IT factors that most adversely impacted educators’ delivery of the academic programme, was the student element (students’ internet access, students’ access to IT equipment, students’ proficiency with technology and data costs for students). The IT factors negative impact was mostly also intensified amid the pandemic.

Implications/Originality/Value: Far from being just a disruption, the pandemic is an indication of the urgent need to build sustainable higher education institutions to ensure that educators deliver quality academic programmes to all. The research obtained an understanding of IT factors (past and present) that may hinder educators’ orientations towards the future. Bringing to the fore the IT hindrances, educators can act by means of their environment, to enable teaching to continue under all conditions.
