Authors: Fan Yonghong , Zhang Jinyan , Han Daoping
Published: June 2023

Due to the harsh working environment and various types of faults in mine hoists, the implementation of conventional detection is relatively difficult. In order to improve the maintenance and fault detection efficiency of mine hoist, a portable vibration detection system is designed and applied in this paper, which can judge the type and characteristics of mechanical faults according to the different responses of vibration signals. According to the test conditions of the vibration system, the overall structure and functional composition of the hardware system are established. The key functional modules are designed, including signal conditioning module, main control module, vibration sensor and power management module. The main reasons that affect and produce the hoist fault and mechanical vibration are analyzed. The wavelet packet analysis method is proposed to realize the decomposition of low frequency and high frequency signals to improve the signal resolution of the whole frequency band in the frequency domain. The vibration test system has the function of real-time data transmission and control. The realization methods include WiFi and reserved RS485 communication interface, which can match the communication rate with the data sampling rate. The amplifying circuit of the electric signal is designed to effectively ensure that the output voltage of the charge amplifier is within the input range of the amplified ADC value. In order to verify the working effect of the system, the most common gearbox and bearing failures are taken as examples. The response signals of vibration test and diagnosis can be effectively obtained, and the fault types and characteristics can be accurately judged. Through confusion matrix analysis, the reliability of the system detection index is effectively verified. The research results show that the data of the vibration detection system is stable and reliable, and can achieve good troubleshooting effect. It also can be known that different fault types can excite different vibration responses, especially at resonance frequencies. According to the verification, the data of the vibration detection system is stable and reliable, and can achieve good troubleshooting effect.

Published: June 2023

Acid soils contain elevated concentrations of mobile aluminium (Al) ions which are toxic for plants. Plants form symbioses with the rhizosphere microorganisms stimulating plant growth and affecting Al availability. Here, for the first time the approach based on the ability to immobilize Al in soil was applied for initial selection of beneficial rhizosphere microorganisms. Al-Immobilizing yeast Rhodotorula sp. AL1 and 12 bacterial strains assigned to various genera and species were isolated from the rhizosphere of pea cultivated in acid soils. Immobilization of Al was related to the increased pH of the environment and the formation of insoluble Al phosphates in soil. The strains differed in possessing beneficial properties such as modulation of the nutrient element (Ca, Fe, K, Mg, Mn, P) concentrations in soil, production of phytohormones (auxins, abscisic and gibberellic acids, ethylene), utilization of 1-aminocyclopropane-1-carboxylic acid and organic components typical for root exudates, acetylene reduction and antifungal activities. Eight strains promoted root elongation of radish seedlings by 30÷50 % with a maximal effect exerted by Cupriavidus basilensis strain D39. Taking together, the selected microorganisms are promising models to study the mechanisms of plant-microbe interactions in the presence of toxic Al and improving Al tolerance of plants in acid soils.

Authors: Chaabna Naila , Naili Oumaima , Ziane Nafissa , Bensouici Chawki , Dahamna Saliha , Harzallah Daoud
Published: June 2023

Background:

Oxidative stress is implicated in many neurodegenerative disorders, such as
Alzheimer’s disease. As an alternative, Punica granatum peels are widely used in the treatment of several
ailments. To date, this is the first study on the anti-acetyl/butyrylcholinesterase effects of diethyl
ether extract from Algerian pomegranate peels.

Objective:

This research aimed to evaluate the content of total phenolics, flavonoids, flavonols, and tannins
in Punica granatum peel crude extract and its fraction diethyl ether, as well as to assess its antioxidant
and neuroprotective activities.

Methods:

The total phenolic, flavonoid, flavonol, and tannin contents in the extracts were evaluated using
spectrophotometric methods. The inhibitory effects on acetyl/butyrylcholinesterase were assessed
using the in vitro models. In addition, several methods were used to investigate the antioxidant capacity
of extracts, including 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-
6-sulfonate) (ABTS) free radicals scavenging, phenanthroline, reducing power and cupric ion reducing
antioxidant capacity (CUPRAC) assays.

Results:

Phytochemical analysis revealed that the diethyl ether extract recorded the highest content of
total phenolics, flavonoids, flavonols, and tannins with values of 643.3 ± 9.96 μgGAE/mg, 78.97 ± 9.97
μgQE/mg, 31.32 ± 1.79 μgQE/mg and 96.6 ± 13.65 μgTAE/mg, respectively. Moreover, the diethyl
ether extract exhibited the strongest activity in the DPPH scavenging assay (IC50=3.36 ± 0.11 μg/mL),
ABTS scavenging assay (IC50=1.46 ± 0.10 μg/mL), CUPRAC assay (CA0.5=3.62 ± 0.36 μg/mL), phenanthroline
assay (CA0.5=1.04 ± 0.10 μg/mL), reducing power assay (CA0.5=4.14 ± 0.32 μg/mL), antiacetylcholinesterase
assay (IC50=114.86 ± 13.66μg/mL), and anti-butyrylcholinesterase assay
(IC50=147.00 ± 10.41 μg/mL).

Conclusion:

The present study has shown the extracts from Punica granatum peel to be a rich source of
bioactive compounds, potent antioxidants, and cholinesterase inhibitors. They could be considered as
natural agents that can be used in anti-neurodegenerative pharmaceutical formulations.
Bioaugmentation for Pollutant Removal
Authors: Rashama Charles , Gorimbo Joshua , Ijoma Grace N. , Bhondayi Clayton , Matambo Tonderayi S.
Published: June 2023

Environmental pollution management through conventional methods in the
wake of new, recalcitrant, and increasing pollutant loads are no longer adequate or
sustainable. Bioaugmentation for pollutant removal is an environmental (water and
soil) decontamination approach alternative to the popular and traditional physico.chemical methods. Despite bioaugmentation’s attractiveness based on being greener
than the traditional methods, there are still several bottlenecks towards operating some
bioaugmented processes optimally. Most bioaugmentation problems arise during
upscaling successful lab-scale trials to industrial operations. In most cases, the
bioaugmented micro-organisms survive for just a short span of time before their
populations decrease prior to completion of the pollutant removal task. Research on
various aspects meant to address this and other bioaugmentation challenges has been
partly successful and such efforts are still ongoing. As part of evaluating and
optimising bioaugmentation processes, sustainability concepts should always be
considered at every stage of these activities. The application of bioaugmentation
techniques is also gaining popularity in other industries, such as biogas production.

Published: June 2023

The present study aims to investigate wastewater treatment of hormones by oak jaft and tea waste adsorbents. Various factors were used to evaluate the adsorption process, such as the initial pollutant concentration, adsorbent concentration, contact time, and pH. The results showed that both adsorbents, jaft, and tea waste, can adsorb 17β-estradiol. Maximum adsorption was 82.4% for jaft adsorbent and 81.5% for tea waste at 85 min, 7 g/L of adsorbent dose, and pH = 4.5, respectively. The adsorption equilibrium was performed using Langmuir, Freundlich, and Liu models, based on the results, Freundlich model with R2 values >0.97 demonstrated better agreement with the adsorption experimental data. To obtain information on adsorption velocity, three models of pseudo-first-order, pseudo-second-order, and Elovich were used. The findings revealed that the pseudo-second-order model with R2 > 0.98 is a better fit for the experimental data. Therefore, the jaft adsorbent and tea waste can be used as effective and economical adsorbents for the removal of organic pollutants in wastewater treatment plants.

Increasing developments on the application of copper complexes as dyes are due to their dual function in dye-sensitized solar cells (DSSCs) as redox mediators and dye sensitizers. The economical (abundance, low cost) and environmentally friendly properties of copper motivate researchers on the use of copper complexes for replacement of ruthenium-based dyes in solar cells. A novel [Cu(I)(2,9-dmp)(phen-dione)]PF6 (A2) bearing polypyridyl ligands, 1,10- phenanthroline-5,6-dione (phen-dione), 2,9-dimethyl-1,10-phenanthroline (dmp) was prepared by metal complexation reaction. The photofunctionality of A2 as a promising photosensitizer in DSSCs was studied. Interestingly, A2 exhibited two absorption peaks, one is detected in the ultraviolet region due to pi-pi* transition and the other is a metal-to-ligand charge transfer (MLCT) band at 405nm in the visible region. A2 was compared to the same complex with Cu(II) ion as the metal centre which only absorbed light in the ultraviolet region thereby implying limited use of Cu(II) complex in its light harvesting application. The photofunctionality of A2 was studied by employing it as an active material for photoelectric conversion by engaging it with ITO to create a photoanode. Upon light irradiation, an anodic current was observed. In conclusion, introduction of Cu(I), instead of Cu(II), in polypridyls ligands resulted in successful enhancement of photophysical properties of A2, making the photoanode of A2 suitable for light harvesting applications.

A LITHOPEDION – AN UNUSUAL CALCIFIED ABDOMINAL PREGNANCY: A CASE REPORT
Authors: Ike Sulistiyowati  , Siswidiyati  , Setyawan Agung , Arifah
Published: June 2023

Introduction: Lithopedion is an ectopic pregnancy that progresses to fetal mortality and calcification, as described in the introduction. It is uncommon, with a reported incidence of 1.5% to 2% of all ectopic pregnancies. The fetus expires and is not absorbed by the mother's body, but it evades maternal immunity by surrounding itself with a calcified shell. Lithopedion can be diagnosed through abdominal X-rays, ultrasonography, and CT imaging.
Case presentation: A 73-year-old female complaining of abdominal mass for over three decades and radiating pain to the right hip for a month. The patient is multipara with a history of habitual abortion. There was an immobile abdominopelvic mass in palpation. The ultrasound showed a large calcified mass in the pelvic cavity. Abdominal and pelvic CT revealed a mummified fetus, depicting great detail of the fetal anatomy surrounded by a calcified membrane. The uterus was normal. Our case is suitable with lithokelyphopedion.
Conclusion: Lithopedion is a seroius condition associated with high maternal and perinatal mortality rates. The condition was not identified during prenatal visits. A thorough history and physical examination are as important as imaging investigations in this setting.
Keywords: lithopedion, lithokelyphopedion, calcified abdominal mass

Published: June 2023

In the past three years, covid-19 viruses have spread rapidly worldwide, while low and middle-income countries were affected mostly so far. Emergency limits were imposed due to the rapid infection and significant mortality rates. Only emergency medical treatments are available during these shutdowns and lockdowns in India. All non-emergency treatments, such as Breast Cancer Screening Program (BCSP), have been temporarily halted due to the huge number of deaths caused by coronavirus. However, the ability of BC screening programs to improve survival rates while lowering mortality rates has been well demonstrated. Suspension may result in poorer outcomes for patients with BC. In this regard, early detection and treatment are critical for increased survival and long-term quality of life. Thus, we have taken breast cancer patients' data for the last six years i.e. from 2016 to 2021 in India to properly evaluate and analyze for our research. Assessing recent results for various features from, modeled evaluations can aid pandemic responses. Besides that, we proposed a novel method that implements the EDA technique to graphically represent BC patients' data. This experiment was done using Python programming language on Jupyter 6.4.3 platform. We found the sudden rise of BC patients from lakhs to millions in 2019. This signifies the deadly coronavirus has greatly affected people during the pandemic days when people are more serious about this virus rather than screening their breasts.

INFLUENCE OF REGIONAL TRANSPORT ACCESSIBILITY ON DEVELOPMENT OF SETTLEMENTS: A CASE OF VISAKHAPATNAM REGION
Authors: Jain Jagrati , V Sai Sesidhar , Gupta Naina
Published: June 2023

The evolution of road development started with the idea of connecting metropolitan cities with the surrounding region. “All roads lead to Rome” which also shows us that, urban development attracts transport infrastructure. But eventually, settlements started to evolve in close proximity to the roads, which shows that development is followed by a transportation network. This has led to a common debate on what should come first, Opportunities/Settlement or Transport Infrastructure. In view of the existing literature, the interdependency of Regional Development and Transport Infrastructure can be classified under three categories which are 1. Transport system (Infrastructure) follows regional development, 2. Infrastructure development as an inductor of regional development and 3. Equality in development emphasizes balanced economic growth and infrastructure in a region. (Botrić, Šišinački and Škuflić, 2006). This study is an attempt to understand the development of the Visakhapatnam district in a regional context and its relation to the regional transportation network. The relationship between the accessibility of regional transport at the nodal level and the development of major settlements has been studied for the same. After analyzing various indicators of development and transportation infrastructure, an impact assessment of two indicators has been done. One of the indicators to study development is the growth rate in terms of the population of the Visakhapatnam region and the indicator to study transport accessibility is Shimbel’s index of major nodes in the regional network. The Geographic Information System has been used as a tool to develop the Road network and to generate the initial connectivity matrix for calculating the Shimbel Index. After obtaining the data related to the indicators of regional development and transportation accessibility, regression analysis has been performed which shows the relationship between the development of major settlements and accessibility.
SOCIAL HOUSING ALLOCATION IN SCOTLAND: THE ADVERSE SELECTION ISSUES
Authors: Mahamood Nur Medeena , MacGregor Bryan , Schulz Rainer , Ab Majid Rohayu , Wan Rodi Wan Norhishamuddin
Published: June 2023

Since the social housing in Scotland is delivered through the public purse, ideally, the social landlords should allocate their stock efficiently to the right recipients. However, a social landlord may occasionally be subjected to adverse selection situations when applicants withhold certain information during the social housing application. Within the information theory spectrum, adverse selection stems from the belief that humans tend to act opportunistically by putting their self-interest first above others’ interest. While there is ample evidence of vast adaptation of the information theory in different fields and sectors, there is still a remaining gap in the information theory application in understanding the actors’ interaction in the social housing sector. By utilising semi- structured interviews with the housing officers from one case study, ten (10) housing officers from the case study in Aberdeen participated to share their views and experience during the pre-allocation stage. Three (3) broad themes were discovered which consist of withholding information, exploiting the loophole in the system and finally, lack of ways in verifying the information. Data has been analysed through a combination of thematic and content analysis. The thematic analysis primarily aims to establish common themes across settings. The content analysis is employed to support the thematic analysis by conducting a textual investigation and subsequently establishing the frequencies of the event shared by the housing officers. The findings yielded some noteworthy results that signified the matters commonly manipulated by the applicants, leading to adverse selection situations during the pre-allocation stage. It produces critical insights on the issues that the social landlord should thoroughly assess during the pre-allocation stage in improving their allocation practice. Predominantly, helping them to meet the right target recipients in the social housing allocation.

The economic and social developments in Malaysia have encouraged internal migration of locals from rural to urban areas, in response to this migration, the government initiates high-rise developments for housing to fulfil these movements. Maintenance work practices aims to benefit the building’s operational age. Maintenance includes all building elements including the façade, flooring, plumbing, electrical and structural maintenance. The aim of this study is to identify the most common maintenance issue that occurred and reported within selected strata schemes. The objective is to identify maintenance issues as reported and observed by strata management bodies and which have the highest cost impact according to the management bodies. A survey involving 50 strata management bodies within the Klang Valley amongst low and medium low-cost strata schemes were conducted and analysed. The result shows that the top three most common maintenance issues are clogged plumbing roofing structure, leakage, and sewer pipe maintenance whilst maintenance with highest cost impacts are relating to general repair, maintenance works and general electrical supply maintenance. Other problems include small but repetitive repairs such as corridor lightings, drainage clogging, leakages and other works that generally affect the residents’ use and enjoyment of the common properties.

Authors: Fedoseev V. B.
Published: June 2023

Size effects during phase transformations change the composition of coexisting phases in ternary mixtures. The consequence is a change in the distribution coefficients of the components, which is of interest for microextraction. The concentration dependence of the degree of extraction for separable mixtures (aniline-methylcyclopentane-hexane and water-phenol-toluene) in submicron drops was simulated by the methods of equilibrium chemical thermodynamics. The concentration dependence of the degree of extraction during microextraction for submicron droplets is constructed. Keywords: phase equilibria, microextraction, thermodynamic modeling, size effect, ternary system.

The features of the formation of an intermetallic Ni3Al coating by cold spraying of a Ni-Al powder mixture mechanically processed in a planetary mill and prepared in a V-shaped mixer are presented. It is shown that the powder deposition efficiency is 1.5 times higher when coatings are obtained from a mechanically treated powder mixture of Ni and Al components. Subsequent high-temperature treatment in the furnace chamber creates a condition for the formation of an intermetallic compound of the Ni-Al system of various stoichiometric proportions. Keywords: cold spray, composite material, high-energy planetary mill, nickel, aluminium, titanium nitride, X-ray analysis.

Numerical modeling of the cooling of a vapor-gas mixture by evaporating water drops has been carried out. An expression is proposed using the characteristic temperature, which determines the dependence of the cooling time on the initial temperature of the mixture. A technique for determining the characteristic temperature based on the results of numerical simulation is presented. An estimate of the error in the results of using the obtained expressions is made. Keywords: vapor-gas mixture, thermal relaxation, numerical simulation, heating and evaporation of droplets, vapor-gas mixture cooling time, characteristic temperature.

Background

Multimorbidity and frailty are characteristics of aging that need individualized evaluation, and there is a 2-way causal relationship between them. Thus, considering frailty in analyses of multimorbidity is important for tailoring social and health care to the specific needs of older people.

Objective

This study aimed to assess how the inclusion of frailty contributes to identifying and characterizing multimorbidity patterns in people aged 65 years or older.

Methods

Longitudinal data were drawn from electronic health records through the SIDIAP (Sistema d’Informació pel Desenvolupament de la Investigació a l’Atenció Primària) primary care database for the population aged 65 years or older from 2010 to 2019 in Catalonia, Spain. Frailty and multimorbidity were measured annually using validated tools (eFRAGICAP, a cumulative deficit model; and Swedish National Study of Aging and Care in Kungsholmen [SNAC-K], respectively). Two sets of 11 multimorbidity patterns were obtained using fuzzy c-means. Both considered the chronic conditions of the participants. In addition, one set included age, and the other included frailty. Cox models were used to test their associations with death, nursing home admission, and home care need. Trajectories were defined as the evolution of the patterns over the follow-up period.

Results

The study included 1,456,052 unique participants (mean follow-up of 7.0 years). Most patterns were similar in both sets in terms of the most prevalent conditions. However, the patterns that considered frailty were better for identifying the population whose main conditions imposed limitations on daily life, with a higher prevalence of frail individuals in patterns like chronic ulcers &peripheral vascular. This set also included a dementia-specific pattern and showed a better fit with the risk of nursing home admission and home care need. On the other hand, the risk of death had a better fit with the set of patterns that did not include frailty. The change in patterns when considering frailty also led to a change in trajectories. On average, participants were in 1.8 patterns during their follow-up, while 45.1% (656,778/1,456,052) remained in the same pattern.

Conclusions

Our results suggest that frailty should be considered in addition to chronic diseases when studying multimorbidity patterns in older adults. Multimorbidity patterns and trajectories can help to identify patients with specific needs. The patterns that considered frailty were better for identifying the risk of certain age-related outcomes, such as nursing home admission or home care need, while those considering age were better for identifying the risk of death. Clinical and social intervention guidelines and resource planning can be tailored based on the prevalence of these patterns and trajectories.

Dendrobium is the second largest genus in the Orchidaceae family. Dendrobium section Spatulata is widely cultivated in Indonesia due to its ease of cultivation, high economic value and adaptability, and extended flower shelf life. In this study, we have conducted a breeding program for developing new cultivar of Dendrobium section Spatulata through interspecific hybridization. This study is aimed to investigate the genetic variation and genomic constitution of the eight hybrids and their corresponding parental lines resulted from interspecific hybridization using SRAP markers. Dendrobium section Spatulata hybrids produced by interspecific hybridization are genuine hybrids with substantial genetic variability based on flower morphology, including labellum shapes and color intensities, as well as curly horn shapes and color intensities. The SRAP marker, which was utilized to genotype the hybrid and parental lines, exhibited a significant degree of polymorphism, and may be used to distinguish each accession. The UPGMA dendrogram and PCoA biplot showed that all the hybrids were grouped with their corresponding parental lines based on their genetic background and genomic constitution. These findings are critical for genetic improvement of the Spatulata orchid to develop novel varieties.
