Published: June 2023

Plastic waste has become one of the biggest problems due to their excessive use. Decomposition of bioplastics is very difficult as a result its causes lot of negative impact to landfill and water pollution. The most possible solution to overcome this problem is to substitute synthetic polymeric materials with biodegradable materials suchas bioplastics. Food wastes can be transformed into environment friendly bioplastics, which will not only reduce environmental pollution due to natural fermentation of these wastes, but also generate National revenue besides generating employment potentials. These polymers can be degraded environmentally by microorganisms and water in compost piles. Application of Bioplastics has several advantages over conventional plastics such as lower carbon footprint and greenhouse gases (GHG) emissions, lower energy cost in manufacturing, reduction of permanent litter, and much safer to the environment. In food Industries, the need for high-standard storage features and the urge for packaging with high economic, low ecological impact, ease of customization, and low encumbrance can be answered by compostable or degradable bioplastics where kitchen waste may take essential role. Advancements in biomedical applications of bioplastics lead to the development of drug delivery systems and therapeutic devices for tissue engineering. Nanocellulose and its composites, which may be obtained from the processing of kitchen wastes, may result in potential and economical sources for green plastic studies about the fabrication of medical implants, either in dental, orthopedic, or biomedical fields.

Over the last two decades, numerous analytical methods for determining acrylamide concentration in a wide range of food products have been developed. Some studies focused on the methods of extracting acrylamide from complex food matrices. In the present study, solid Phase Extraction (SPE) and Gas Chromatography-Nitrogen Phosphorus Detector (GC-NPD) analysis were employed to develop a simple and cost-effective acrylamide determination method. Method validation and optimization steps were carried out and used to determine acrylamide concentrations in potato chips purchased from Yemeni markets. In the concentration range of 0.1- 5 ppm, the validated method demonstrated good sensitivity within a 0.012 ppm limit of detection (LOD) and an excellent linearity of 0.996 correlation coefficient. Eighteen samples of potato chips purchased from local markets in Sana'a, Yemen, were analyzed using this method. Three of the 18 samples of interest contained various acrylamide concentration levels of 879.4, 795.6, and 754.7 ppb. These were higher than the EU Commission's indicative value for the acrylamide in potato chips (750 ppb). As a result, the optimized GC-NPD protocol proved to be useful for the acrylamide analysis, paving the way for the development of an acrylamide quantification prescreening tool in the food industry.

Vegetables are renowned for their nutritional value, as they are rich sources of dietary fiber, minerals, and vitamins offering a wide range of health benefits. They also possess antioxidative properties that contribute to overall well-being. The aim of this study was to evaluate the contamination of heavy metals like Arsenic (As), Cadmium (Cd), Chromium (Cr), Copper (Cu), Iron (Fe), Manganese (Mn), Nickel (Ni), and Zinc (Zn) in the agriculture soil and most frequently consumed vegetables including; Sweet Potato (Ipomoea batatas), Turnip (Brassica rapa), Onion (Allium cepa), Carrot (Daucus Carota), Garlic (Allium sativum), Radish (Raphanus sativus), Lotus (Nelumbo nucifera), Potato (Solanum tuberosum), Beetroot (Beta vulgaris), and Ginger (Zingiber officinale) collected from various sites of District Ghotki, Sindh. The agriculture soil and vegetable samples were digested, and heavy metal levels were determined using Atomic Absorption Spectrophotometer (AAS). The Zn content was found higher in all vegetable samples. Cu, Fe, Mn, and Zn concentrations were found within the permissible levels of the Food and Agriculture Organization and World Health Organization (WHO/FAO). However, the concentrations of As, Cd, Cr, and Ni were found higher than the permissible limit suggested by WHO/FAO. Hazard index (HI), target hazard quotient (THQ), daily intake of metals (DIM), and estimated daily exposure to heavy metals (EDEM) were also measure. The hazard index (HI) values of As for all the vegetable samples were greater than 1, indicating potential health risks to those consuming these vegetables.

Published: June 2023

Innovation, the globalization of markets, changing living standards, and increasing average life expectancy are among the factors influencing work activity and impacting workers' performance. Within this context, the significance of time management (TM) is underscored as a critical means of rationalizing a limited and valuable resource, namely time. Effective time management is essential for achieving a balance between professional and family obligations while maintaining a high quality of life and achieving optimal outcomes. Although not a new phenomenon, the importance of time management has grown significantly in contemporary society. Motivated by the awareness of this issue, the present study aimed to validate a self-diagnostic tool for time management (TMST) that enables a quick assessment of an individual's time management skills and facilitates the development of personalized plans of action and improvement based on the identified profile. The results demonstrate a significant enhancement in all three sections of the TMST (time perspective, self-recognition, and time management) following the implementation of the recommended strategies. Furthermore, the conduction of interviews to evaluate and validate the TMST revealed that the tool adds value to time management, thereby contributing to both theoretical and practical advancements in this field.

Authors: Ahmad Jamal Sarah Alia , Saiful Bahar Afiqah Aisyah
Published: June 2023

Similar physical features of two traditional Chinese musical instruments, Guqin and Guzheng, have mistakenly led the general public to discern them as complementary duos. Contrary to this belief, both instruments have different historical backgrounds and purposes. Therefore, this research is conducted to (i) identify the identity of the two instruments and (ii) signify the representations of each instrument. This qualitative research adapted the descriptive comparative research design and used individualizing as an analysis method. In conclusion, despite the similarities in shape and playing techniques, these two instruments depict different messages, leading to other representations and purposes.

Authors: Mohd Fateh Mohd Ashraf , Arshad Ruslan Affendy , Ahmad Marzuki Siti Maryam , Yusof Mohd Reeza
Published: June 2023

Effective communication is becoming increasingly important in project construction because of the growing demands of the projects. Fundamental to the successful delivery of projects in the construction industry is high-quality communications.  The objectives of this paper were to investigate communication methods commonly used in construction projects, to identify factors contributing to communication breakdown, and to suggest actions to minimise communication breakdown during the construction phase between consultants and contractors. Through a comprehensive literature review the communication channels, modes and mediums were recognised. The contributing factors were categorised into project characteristics, personal attitude, communication method, communication management, communication barrier and external aspect. While, the actions to minimise communication breakdown were extracted from previous studies and classified into communication development, communication management and communication method. A quantitative method (questionnaire survey) with a close-ended questionnaire with experienced industry practitioners from a large population of 135 respondents comprising consultants, contractors and developers was used for the data collection. It produced results that generalise, compare and summarise all collected data. The study identified personal attitude as the highest contributor to communication breakdown and communication management was the most effective element to minimise the communication breakdown. It would take a combined effort on the part of all construction parties from consultants, contractors and subcontractors to the project owner to minimise communication breakdown. The findings might help to achieve project success through the improvement of communication between consultants and contractors during the construction phase.

Published: June 2023

Route accessibility is essential infrastructure, facilitating more convenient transit for individuals. Nonetheless, the seasonal monsoon can lead to flooding and impair the accessibility of local transportation, especially in hilly-lowland areas. This study aims to investigate an alternative route access for safe travel from Kota Marudu to Kota Kinabalu, Sabah, during the floods with GIS path analysis and MCDA method. The slope, rainfall, land cover /land use (LULC), distance from the river and river density were utilized to construct the flood susceptibility map using Analytic Hierarchy Process (AHP), while path analysis was applied to find the accessible and safe routes. There are two other routes in the study region, one of which may be utilized as a suitable route. A new route should be considered to create roads in the higher area. The alternate route map suggested in the study is a beneficial tool as caution during the rainy season. As the flood's extent is simply an estimate, it is only possible to forecast the event, and sometimes can result in unexpected tragedy.
Development and generalization of the method of reflections in problems of electrostatics and thermal conductivity of plane-layered media
Authors: Petrin A. B.
Published: June 2023

The method of mirror reflections of electrostatics for a point charge located next to a plane-layered medium consisting of a single film on a dielectric half-space is formulated. The method is generalized to the case of an arbitrary system of charges. The proposed approach is applied to mathematically similar problems of electrostatics and stationary heat conduction of plane-layered media. In particular, the problems of finding distributions of the electrostatic potential around a conducting sphere, an ellipsoid of revolution and a drop-shaped body located near the dielectric film on the dielectric half-space. It is shown how to apply the results obtained for electrostatic problems to similar problems of finding the temperature distribution of uniformly heated bodies of the same geometry located near a heat-conducting film in a heat-conducting half-space. Keywords: plane-layered medium, mirror reflection method, electrostatics, thermal conductivity.
On a paradox" in the scattering theory
Authors: L.A.Apresyan
Published: June 2023

The solution of the "paradox" in scattering theory is considered, according to which the extinction cross section is expressed in terms of the forward scattering amplitude (the so-called "optical theorem"), whereas for a point source, and as a consequence, for any emitter located at a finite distance from the scatterer, a similar ratio is often written through a scattered field near the emitter, i.e. determined by "backscattering". A clear picture of the formation of radiation losses during the transition of energy from the source to the scatterer is presented. It is shown that although the field backscattered to the source determines the change in its radiation characteristics (the Purcell effect), the optical theorem includes an extinction factor which is generally related to the work of the incident wave on the currents induced in the scatterer. This factor passes into the forward scattering amplitude in the limiting case of a plane incident wave. Keywords: optical theorem, energy conservation, radiation losses, Purcell effect, point source of radiation.

Video Consultations in Primary Care Outside Office Hours
Authors: Nebsbjerg Mette Amalie , Bomholt Katrine Bjørnshave , Vetsergaard Claus Høstrup , Christensen Morten Bondo , Huibers Linda
Published: June 2023

Background

Out-of-hours primary care (OOH-PC) is facing increasing demands and workload with many negative consequences, including longer waiting time and increased risk of treatment delay and safety incidents. During the COVID-19 pandemic, video consultation (VC) was introduced as an alternative to face-to-face contact. We hypothesize that VC contributes to sustainable OOH-PC by changing patient flows, decreasing workload, and reducing waiting time.

Objective

This study aims to evaluate the use of video in telephone triage in OOH-PC by studying user rate, the effect on contact patterns, and patient characteristics related to receiving a VC.

Methods

We conducted a register-based study of VC use in OOH-PC, including all Danish residents contacting OOH-PC in the regions of Central Denmark, Southern Denmark, Northern Denmark, and Zealand. The study population will be followed from birth, immigration, or March 1, 2020 (whichever came last), until death, emigration, or December 31, 2021 (whichever comes first). We will use national registers, linking data with the unique personal identification number. We plan to conduct descriptive analyses, calculating the proportion of VC of all teletriage consultations per month during the study period. We plan to use regression models to measure the association between VC and triage outcome and the association between VC and patient characteristics, calculating risk ratios and 95% CIs. Both crude and mutual adjusted risk ratios for patient characteristics will be presented.

Results

Data analyses started in May 2022.

Conclusions

A preliminary conclusion will be presented at the conference.

Manufacturing of an effective, eco-friendly nano insecticide with aiding of green alga Chlorella vulgaris in contrast with the traditional insecticide.
Authors: Shafeeq Maan Abdul Azeez
Published: June 2023

This study aims to establish an aqueous extract of Chlorella vulgaris as a green factory to manufacture titanium nanoparticles and to apply these nanoparticles to control the house flies (Musca domestica). Since the crystallite size of prepared titanium nanoparticles was 27.39 nm. Furthermore, the observed size for bulk particles ranged (from 92.33-249.6) nm through SEM.  While for nanocrystalline the size ranged (from 9.395- 206) nm. Several phytochemicals were detected within algal extracts such as phenols, tannins, alkaloids, flavonoids, resins, and saponins. All these active compounds participated in nano-synthesis by acting as reducing and stabilizing agents. finally, titanium nanoparticles were used as a controlling agent against house flies (Musca domestica) and compared with traditional insecticides (Imidacloprid). High mortality percentages reached 100% against 1st larval stage, 70% against 3rd larval stage, and 93.3% in adult flies. These fatalities were higher after using Imidacloprid for all tested stages. Many phenotypic distortions were also caught in houseflies treated with TiO2 NPs prepared by Chlorella, such as; failure in pupal emergence and maturity, incomplete development in the head, legs, and wings, and disappearance in genital organs. It has shown that Chlorella Vulgaris is a good candidate for nanomanufacturing and a rich naturally derived Nanopesticide.
Techno-economy of lithic raw materials in Piedmont (north-western Italy): A first life-like scenario
Authors: Daffara Sara , Berruti Gabriele Luigi Francesco , Caracausi Sandro , García-Rojas Maite , Arzarello Marta
Published: June 2023

Data about Palaeolithic peopling, settlement dynamics and techno-economy of the south-western margin of the Alpine region are sketchy. In this area, the lack of systematic research and the scarcity of lithic raw materials, spread the idea that Piedmont was not inhabited during Palaeolithic. In 2009, the re-starting of the excavations at the Ciota Ciara cave, gave rise to new questions and to the development of research projects at a regional scale.
The Ciota Ciara cave is the only Middle Palaeolithic site object of multidisciplinary and systematic investigations. Its lithic assemblage, analysed through a techno-economic approach, allows to understand in detail the technological choices and the land mobility of the Neanderthal groups on a local and sub-regional scale. Other Middle Palaeolithic assemblages are known in the region and are all issued from surface collections. They come from the northern part of the region, from Vaude Canavesane, Trino, Baragge biellesi and Colline Novaresi. The technological study of these assemblages led to the identification of strong similarities in the technological choices of the Middle Palaeolithic human groups: they based their technology on the exploitation of vein quartz, a rock diffused all over the regional territory, from time to time accompanied by other local (spongolite, rhyolite, metamorphic rocks, jasper) and allochthonous (radiolarite and flint) lithic resources, with technological adaptation to their quality and mechanical properties both when it comes to predetermined methods (Levallois and discoid) and when expedient reduction sequences are used. Concerning Upper Palaeolithic, the only lithic assemblage issued from an archaeological excavation (and therefore with a clear stratigraphic context) is that from the Epigravettian site of Castelletto Ticino. Other lithic artefacts referable on a techno-typological basis to Upper Palaeolithic are from Trino and Colline Novaresi. As for Middle Palaeolithic, the techno-economic approach used in the analysis of these lithic assemblages, allow to have, for the first time, reliable data at a regional scale.
In this work we present the data obtained after about ten years of research in Piedmont: they outline a scenario where, even in the limits of analysis mostly based on materials issued from surface collections, we can see both clear differences between the Middle and the Upper Palaeolithic technological behaviours and hypothesise the land mobility of the hunter-gatherers’ groups that inhabited the region.
Cal Sitjo: A new Mesolithic to Neolithic sequence in a chert-rich region (Sant Martí de Tous, NE Iberia)

Published: June 2023

Cal Sitjo is a new archaeological sequence located in a chert-rich region of the NE Iberian Peninsula, in the town of Sant Martí de Tous (Anoia, Barcelona). The area has undergone significant anthropisation and several archaeological sites (e.g., Vilars de Tous), quarries and workshops for the exploitation of chert (e.g., La Guinardera) have been documented, corresponding to different periods. The abundance of chert made this region an almost obligatory passageway for hunter-gatherer communities such as those occupying the nearby cliffs of Cinglera del Capelló (Capellades), located at a direct distance of 15 km, as well as an ideal settlement for later farming communities.
Discovered in 2019, the first excavation campaign was carried out in the fall of 2020. Dates have been obtained from a known sequence of around 8 m, providing a chronological framework that ranges from the Mesolithic to the Middle Neolithic. The preliminary results of this excavation have brought to light lithics, ceramics and charcoals from the Neolithic levels (Levels 3 and 4), and faunal, lithic and charcoal remains from the Mesolithic levels (cleaning section).
Our preliminary results confirm that this sequence is an ideal location for a diachronic study of the evolution from the last hunter-gatherers to the first farmers, from a paleoenvironmental and technological perspective, as well as in terms of chert management and distribution in a territory with a great abundance of this raw material.

Abstract: Agriculture is the most important sector among all, as it supplies food to people. As the food demand is increasing in our daily life and the population is increasing there is need of increasingin the food production also. The main issue nowadays is that diseases that are causing the food production to reduce. So our main aim is identification of the disease of the plants in early stage so that we can do the early diagnosis and protect crops from the harmful diseases. By doing this we can avoid the damage of crops and also can reduce the loses that farmers suffer from damage of crops. Here we are using image processing technique to identify the disease of the crops so that we can cure the diseases of the crops in early stage. Here we are using Deep learning algorithms like Convolutional neural networks (CNN) for our project that is leaf disease detection. CNN is the best algorithm for image processing as it greatly increases the performance of our model. Nowadays deep learning is the current trend as it solves the most complicated problems easily and can get the highest accuracy.

Abstract: Soil stabilization is a mechanical or chemical alteration of one or more soil properties to create an improved soil material possessing the desired engineering properties. 'e aim of this article was to review bio enzyme-based soil stabilization techniques with an emphasis onBio-enzymes production, mechanism of soil stabilization and future challenges, and opportunities of the sector. Soils are stabilized to increase strength and durability or to prevent erosion and dust generation. Cost-effective soil stabilization technology has been a fundamental part of any construction and is very important for economic growth in any country. In some cases, construction has been challenged due to the high cost of soil stabilization processes. Besides, methods of stabilizations using common stabilizing agents are getting costly. Currently, there is a growing interest to identify new and green technology to improve construction techniques and to expand the road network. Ere fore, the search for new materials and improved techniques to process the local materials has received an increased focus. For developing countries, bio enzymes are now creating an opportunity to improve soil stability with tremendous effectiveness in the overall process of soil stabilization. In the world, bioenzymes have been used in different projects for several years and are generally proprietary products, often of patented formulation that needs intensive field tests. Currently, the use and production of bio enzymes is becoming the most promising key for the advancement of a country by saving time, energy, and finance. It also reduces environmental pollution due to carbon emission by the conventional stabilizers. 'us, a better understanding of this emerging technology is of utmost importance to exploit any improvement it can offer to soil stability. With little research and practice, it is possible to produce soil stabilizing bio enzymes using local raw materials. Due to this, production of low cost, easily and widely applicable, and environmentally friendly enzymatic formulations from locally available raw materials should be the interest of research and academic institutes of any country. system is applied to several major cities across the globe to demonstrate its use and usefulness.

Abstract: Tackling isolation is much more complex than bringing people's private space physically closer. Bullying and harassment among peers, adult abuse and neglect of children, and suicide as a kind of self-abuse are the primary cause of social isolation. To improve the overall well-being of human beings, mental health should be kept in the first place for that. Since mental illness is sometimes stigmatized, sufferers may feel humiliated or embarrassed about needing treatment. Even worse, mental health facilities are stigmatized as depressing, institutional places where no one wants to spend time. So, the study of alternate method of treatment is required which include architectural interventions.
