Determinants of Consumer Preferences for Imported and Domestic Wooden Furniture: Lessons from Addis Ababa, Ethiopia
Authors: Girma Gonche , Melka Yoseph , Belay Teferra 
Published: August 2024

Abstract
Currently, domestic wood product enterprises in Ethiopia are facing increasing competition from imports. Therefore, more needs to be done to address the evolving dynamics in public preference and taste while overcoming the pressure from the import market. However, the wooden furniture sector in Ethiopia is scarcely researched and documented to support the production and marketing system. This study investigated the determinants of consumer preferences for imported and domestic wooden furniture in Addis Ababa, Ethiopia. Multistage sampling was used to select a sample size of 385 consumers who had purchased wooden furniture. Data were collected using a structured questionnaire and analyzed through descriptive statistics, Kendall’s test, and the multivariate probit (MVP) model. The findings revealed that imported wooden furniture scored higher in terms of finishing, color, compatibility with other objects, and design, whereas domestic wooden furniture excelled in terms of durability, environmental friendliness, maintainability, and affordability. The MVP results indicated that wooden furniture preference was influenced by factors such as age, number of years in marriage, family size, number of years living in the city, occupation, and exposure to advertisements. The study recommends that domestic furniture companies enhance the finishing, design, color, and other desirable attributes of their products to attract and satisfy domestic demand, potentially reducing the need for imports. By focusing on improving multiple attributes, companies better cater to the preferences of consumers. Additionally, furniture companies should consider the diverse socioeconomic characteristics of consumers during the production of their furniture products to meet a range of needs.

Published: August 2024

Background
Metabolic dysfunction-associated fatty liver disease (MAFLD) is a rapidly growing global health problem. Despite its growing incidence and potential for significant repercussions, MAFLD is still widely misunderstood and underdiagnosed.

Aim
The purpose of this study was to investigate MAFLD-related knowledge, attitudes, and risk profiles among university students aged 17 to 26.

Methods
A cross-sectional study with 406 university students in Lebanon, equally distributed among males and females, was conducted using a questionnaire that includes demographics, medical information, dietary habits, physical activity, and MAFLD-related knowledge and attitudes.

Results
The findings demonstrated a significant lack of knowledge regarding MAFLD, with more than half of participants (54.7%) having no prior knowledge of the illness. Students exhibited unhealthy lifestyle behaviors such as smoking (68%), insufficient physical exercise (44.1%), and poor food habits (52.5%). Having a family history of heart disease, personal history of diabetes mellitus, a balanced diet and prior knowledge of the disease were associated with a higher knowledge score (p<0.05). A higher attitude score existed among those who have a personal or family history of chronic diseases and those who have a prior negative impression about the disease, prior knowledge of the disease, and those who are physically active (p<0.05).

Conclusion
Despite knowledge gaps, university students in Lebanon have, in general, an appropriate and positive attitude towards MAFLD. We recommend the introduction of focused educational interventions to address the necessity of lifestyle changes among university students and the community as a whole. Developing comprehensive MAFLD prevention methods requires future studies in different age groups and demographics

Published: August 2024

BACKGROUND: Vitamin D deficiency in secondary hyperparathyroidism (SHPT) against the background of chronic kidney disease (CKD) in patients with diabetes mellitus (DM) is one of the key factors in the deterioration of renal function. AIM. To assess the indicators of calcium-phosphorus metabolism in individuals with SHPT against the background of CKD, diabetes and without it to optimize treatment approaches. MATERIALS AND METHODS. A retrospective analysis of 416 medical records with diagnoses CKD3-C5 and SHPT was carried out, of which 112 had a history of diabetes, which were examined and treated in the nephrology department of the in the period from 01. 01. 2018 to 31. 12. 2022. Demographic and anthropometric data were studied, laboratory (total and ionized calcium, total protein, albumin, phosphorus, creatinine, parathyroid hormone, 25(OH)D, alkaline phosphatase) and instrumental (ECHO-CG, ultrasound of the abdominal organs and retroperitoneal space) research methods. RESULTS. Diabetes is the leading cause of CKD among all nosological forms. The level of 25(OH)D in patients without diabetes varied from 9.04 to 152 nmol/l, with diabetes from 8.3 to 77 nmol/l. The average level of 25(OH)D in patients without diabetes (41.7 ± 26.1 nmol/l) was significantly higher than in patients with type 1 diabetes (20.3 ± 14.9 nmol/l) and type 2 diabetes (27.6 ± 19.2 nmol/l) (p = 0.005 and p = 0.003, respectively). 25(OH)D deficiency and insufficiency were more often recorded in patients with diabetes compared with patients without carbohydrate disorders (89 % and 10 % versus 69 % and 19 % respectively), while the optimal level was more common in patients without diabetes (12 % and 1 %, respectively).
Scolochloa marchica Düvel, Ristow & H. Scholz – a German-Polish endemic species of the lowlands and the distribution of S. festucacea (Willd.) Lk. in Poland
Authors: Kruk Jerzy , Ristow Michael , Jedrzejczyk Iwona 
Published: August 2024

In the current study, an extensive worldwide herbarium search, including over 1500 herbarium sheets of Scolochloa festucacea (Willd.) Lk., was performed to find specimens of S. marchica Düvel, Ristow & H. Scholz. The latter is a recently described new species, whose primary distribution was found to be limited to the Brandenburg region in Germany and the Wolin Island in Poland. As a result of the query, S. marchica was not identified in any regions other than those previously known. This indicates that it is a German-Polish endemic species, with a limited distribution range. Taking advantage of flow cytometry, we analysed for the first time the nuclear DNA content of both Scolochloa species and the obtained 2C values correlated exactly with their chromosome numbers. These data allowed us to put forward a hypothesis of evolution of S. marchica from S. festucacea. The new results, together with those previously published, confirmed that we deal with a distinct species. Taking into account recent records of this endemic species, it is currently known from 9 extant and 6 historical localities in Germany. Field search for the species in its only historical locality in Poland, on the Wolin Island, was unsuccessful. The critical revision of herbarium and literature records of S. festucacea from the territory of Poland allowed us to generate an updated distribution map of this declining species, which deserves special protection.
Monetary Policy Transmission in Canada – A High Frequency Identification Approach
Authors: Soosalu Matt 
Published: August 2024

Abstract
I study the effects of monetary policy shocks in Canada on economic and financial variables. With a narrow window around a policy announcement, I create a new set of intraday level, high-frequency monetary policy surprises using the three-month Canadian Bankers’ acceptance rate futures. I use this measure to identify monetary policy shocks as an external instrument in a monthly VAR. Following a 25 basis point contractionary policy shock, I find that the decline in output is more powerful and peaks earlier than previous empirical works show, with a peak decline of 0.5 % points after 18 months. Price level declines are similarly more powerful and earlier, reaching a decline of 0.3 % points after 24 months. In addition, increases in the credit and mortgage spreads indicate the presence of a domestic credit channel of monetary policy transmission for Canada. Finally, I show that the surprise measure is robust to information effects.

An investigation on explicit exact non-traveling wave solutions of the (3+1)-dimensional potential Yu–Toda–Sasa–Fukuyama equation
Authors: Guo Qianqian , Peng Xiaoming 
Published: August 2024

Abstract
This paper is devoted to investigating new non-traveling wave solutions for the (3 + 1)-dimensional potential Yu–Toda–Sasa–Fukuyama (YTSF) equation. By using the generalized variable separation method and extended three-wave approach, the process of solving the (3 + 1)-dimensional potential-YTSF equation is simplified and the interactions of multiple waves are revealed. With the aid of Maple, we derive thirty-six types new exact explicit non-traveling wave solutions with a like-parabolic tail. The main characteristic of these solutions is that they contain three arbitrary functions, which greatly enrich the diversity of solutions. This characteristic shows the novelty of our work. In particular, selecting suitable arbitrary functions, we can obtain traveling solutions, such as kink-wave solutions, solitary-wave solutions, kinky breather-wave solutions, singular solutions and periodic solutions. Then, some dynamical phenomena are exhibited by 3D representation, providing the complicated structure of the non-traveling wave solutions for the (3 + 1) dimensional potential-YTSF equation and their physical interpretation. In addition, our findings improve and extend the existing literature on related topics.

Published: August 2024

Abstract
Integrated miniature spectrometers have impacts in industry, agriculture, and aerospace applications due to their unique advantages in portability and energy consumption. Although existing on-chip spectrometers have achieved breakthroughs in key performance metrics, such as, a high resolution and a large bandwidth, their scanning speed and energy consumption still hinder practical applications of such devices. Here, a stationary Fourier transform spectrometer is introduced based on a Mach–Zehnder interferometer structure on thin-film lithium niobate. Long and low-loss spiral waveguides with electro-optic tuning are adopted as the optical path scanning elements with a half-wave voltage of 0.14 V. A high resolution of 2.1 nm and a spectral recovery with a bandwidth of 100 nm is demonstrated under a high-speed and high-voltage scanning in the range of −100 V to +100 V at up to 100 KHz. A low energy consumption in the μJ scale per scan is also achieved.
Enhanced Drug Dissolution of Nitrofurantoin Using a Solid Dispersion Technique
Authors: Bhosale D. S. , Kalshetti M. S. 
Published: August 2024

Abstract

Background: Nitrofurantoin is a BCS II drug with a low solubility and dissolution rate. Therefore, the pharmaceutical applications of nitrofurantoin are limited. The purpose of the current study was to enhance the solubility, dissolution, and bioavailability of nitrofurantoin by formulating a solid dispersion (SD).

Methods: The SD was developed using 32 factorial designs considering poloxamer 188 and the trituration time as independent variables, and solubility and drug release as dependent variables. The developed SD was characterized for solubility, FTIR, DSC, XRD, in vitro dissolution, and pharmacokinetic studies in rats.

Results: Nitrofurantoin:poloxamer 188 at a 1:1 ratio had higher solubility than nitrofurantoin. The solubility of nitrofurantoin was directly related to the amount of poloxamer 188 and trituration time. In addition, poloxamer 188 concentration was directly related to the DR45 (%), while the rate of stirring was inversely related to the DR45 (%). An FTIR study revealed excellent drug excipient compatibility. The crystallinity of the drug was decreased, which indicated a more amorphous nature of the drug in XRD and DSC studies. Compared to pure drug dispersion, the optimized formulation exhibited a 3.88-fold improvement in the bioavailability of nitrofurantoin, whereas compared to the marketed formulation, a 1.77-fold enhancement in bioavailability was noted.

Conclusion: This study indicated that SD could be a potential carrier system to enhance the solubility, dissolution, and bioavailability of nitrofurantoin.
PENGARUH LEVERAGE, LIKUIDITAS, DAN PROFITABILITAS TERHADAP FINANCIAL DISTRESS DENGAN UKURAN PERUSAHAAN SEBAGAI VARIABEL MODERASI PADA PERUSAHAAN SUBSEKTOR TRANSPORTASI YANG TERDAFTAR DI BURSA EFEK INDONESIA

Like companies in general, transportation sub-sector companies must maintain the company's financial condition so that they do not experience financial distress or the stage of decline in financial condition that occurs before bankruptcy or liquidation occurs. Financial distress is a situation where a company experiences poor financial performance which is characterized by the company experiencing losses for at least two consecutive years. Financial distress occurs before the company experiences bankruptcy. Financial distress can be measured through financial reports by analyzing financial ratios. This research was conducted to test and analyze financial ratios in predicting financial distress. This research is a type of quantitative research to analyze whether leverage, liquidity and profitability can influence financial distress. The population in this research is all transportation companies in 2020-2022 with a total of 25 companies. The sample selection technique used purposive sampling, so that 75 units were obtained and significance analysis was carried out. Data is collected first using documentation techniques. The data analysis tool used is panel data regression using the Eviews 12 program. The research results show that leverage and liquidity show a negative influence on financial distress, while profitability has no effect on financial distress. Company size is able to moderate variable leverage and financial distress. However, company size is not able to moderate the influence of liquidity and profitability on financial distress. Based on this research, investors are expected to be able to make decisions to invest by considering the financial health condition of transportation subsector companies by knowing the risk level of the possibility of the company experiencing financial distress. The government's role is important in supporting companies that are experiencing financial distress, both from a financial and non financialperspective, by providing relaxation in existing policies. And for further research you can add other independent variables such as the amount of institutional ownership, good corporate government (GCG) or those that influence financial distress. Apart from that, we can add differences in the company's financial distress conditions before, during and after the Covid-19 pandemic.

Authors: Joevivek V. , Chandrasekar N. , Saravanan S. 
Published: August 2024

ABSTRACT
The study of heavy minerals in coastal areas provides insights into placer deposition mechanisms, economic mineral enrichment, and the origin of placer deposits. This study describes the distribution and characteristics of heavy mineral placer deposits between Thirukadaiyur in the north and Velankanni in the south along the central coast of Tamil Nadu, India. Sediment samples were collected at 5 km intervals throughout the berm region and brought to the laboratory for heavy mineral separation and quantitative analysis. Single crystal X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray technology (EDX) were used to analyze the structure and composition of heavy minerals. Quantitative results show that magnetite, ilmenite, garnet, zircon and rutile are the dominant heavy minerals in beach sand. The presence of heavy minerals was confirmed by microscopic and XRD analysis, and SEM and EDX results confirmed their properties and origin. Overall, mineralogical and petrological studies have revealed the transport mechanism and variables affecting the process of placer enrichment along the coast.
