BACKGROUND: Concerns about the harmful effects of smartphone use on teenage development have been raised as the use of cell phones among adolescents has risen. OBJECTIVE: This study aimed to examine the associations of smartphone usage patterns with Body Image Distortion (BID) and weight loss behaviors among adolescent smartphone users in Saudi Arabia. METHODS: This population-based, cross-sectional study was conducted from July to October 2022. We assessed the mean daily length of smartphone use and classified it into quartiles using data from a self-reported survey and data on weekday and weekend use. Self-reported body weight and height were collected via an online survey. Out of the 11384 adolescents, the majority was females (65.7%) and was secondary school students (68.9%). RESULTS: The prolonged smartphone use (301 min/d) was found in 36.4% of adolescents, 181–300 min/d in 27.6% of respondents, 121–180 min/d in 22.4% of respondents, while the modest smartphone use (1–120 min/d) was found only in 13.6% of participants. The duration of smartphone use was significantly associated with BID (P= 0.000); students with middle perceived stress levels (51.4%) and no depressive symptoms (68.9%) used smartphones 121–180 min/d sparingly. However, prolonged smartphone use was significantly associated with the presence of depressive symptoms (42.6%) and high perceived stress levels (21.5%). Weight loss behaviors were significantly associated with smartphone use duration. Modest smartphone use was significantly found in students with normal weight (P= 0.00, 71.9%); however, aerobic physical activity weight loss strategy (P= 0.00, 30.9%) was correlated with prolonged smartphone use. CONCLUSION: Adequate parental advice is required to assist teenagers in developing healthy smartphone usage practices. Digital platform companies may increase their social responsibility for the information generated and delivered on their networks, boosting its beneficial effect.

BACKGROUND:

Preoperative prediction of cervical lymph node metastasis (CLNM) in patients with papillary thyroid carcinoma (PTC) is significant for surgical decision-making.

OBJECTIVE:

This study aims to develop a dual-modal radiomics (DMR) model based on grayscale ultrasound (GSUS) and dual-energy computed tomography (DECT) for non-invasive CLNM in PTC.

METHODS:

In this study, 348 patients with pathologically confirmed PTC at Jiangsu University Affiliated People’s Hospital who completed preoperative ultrasound (US) and DECT examinations were enrolled and randomly assigned to training ( n = 261) and test ( n = 87) cohorts. The enrolled patients were divided into two groups based on pathology findings namely, CLNM ( n = 179) and CLNM-Free ( n = 169). Radiomics features were extracted from GSUS images (464 features) and DECT images (960 features), respectively. Pearson correlation coefficient (PCC) and the least absolute shrinkage and selection operator (LASSO) regression with 10-fold cross-validation were then used to select CLNM-related features. Based on the selected features, GSUS, DECT, and GSUS combined DECT radiomics models were constructed by using a Support Vector Machine (SVM) classifier.

RESULTS:

Three predictive models based on GSUS, DECT, and a combination of GSUS and DECT, yielded performance of areas under the curve (AUC) = 0.700 [95% confidence interval (CI), 0.662–0.706], 0.721 [95% CI, 0.683–0.727], and 0.760 [95% CI, 0.728–0.762] in the training dataset, and AUC = 0.643 [95% CI, 0.582–0.734], 0.680 [95% CI, 0.623–0.772], and 0.744 [95% CI, 0.686–0.784] in the test dataset, respectively. It shows that the predictive model combined GSUS and DECT outperforms both models using GSUS and DECT only.

CONCLUSIONS:

The newly developed combined radiomics model could more accurately predict CLNM in PTC patients and aid in better surgical planning.

The purpose of the work is to establish the patterns of structural formation of high-strength cast iron using the thermodynamic theory of phase transformations and to analyze state diagrams of the components of Fe-Si-Mg ligatures. The article presents the results of the analysis of patterns of structural formation of high-strength cast iron when using state diagrams of the "Fe-Si", "Mg-Si" and "Fe-Si-Mg" systems. The concept of graphite formation in high-strength cast iron is considered. The structure formation scheme of high-strength cast iron is presented. Disclosure of the mechanism of processes of formation of spherical and vermicular graphite opens wide opportunities for controlling the structure and properties of high-strength cast iron and contributes to the development of effective technological processes for obtaining cast products for various purposes. It has been established that during the modification of cast iron melt, as a result of a significant redistribution of all elements dissolved in it, purification of impurities (sulfur, phosphorus, etc.) takes place, which allows obtaining the structure of cast iron with nodular graphite with the use of modifiers. Diagrams of the "Fe-Si", "Mg-Si" and "Fe-Si-Mg" systems for the development of the composition of high-strength cast iron are given. After analyzing the data of the given state diagrams, it was concluded that in the composition of spheroidizing ligatures, all compounds of elements are low-melting (tpl < 1300 °С) in relation to the melting temperature of cast iron. During the crystallization of cast iron with the release of austenite, a direct microliquation of silicon with a distribution coefficient less than unity is characteristic, manganese is more evenly distributed in the metal, and carbide stabilizing elements are treated in the liquid phase. The regularities of structure formation of modified cast iron under different crystallization conditions have been established. The analysis of the study of the regularities of the process of the formation of spherical and vermicular graphite and the analysis of state diagrams of the "Fe-Si-Mg" liga-tur components were performed.
Modular-Parametric Principle of Design Development of Gear Hydraulic Machines
Authors:   Central Ukrainian National Technical University, Aparakin Аnton
Published: August 2023

The conventional system of design development of gear-type hydraulic machines and their implementation is not sufficiently perfect for a number of reasons. This system cannot be effective in the conditions of large-scale production. The purpose of the work is to create such a principle of designing a model range of gear hydraulic machines, which optimizes the conditions of production and marketing, with the subsequent reduction of the cost of production. To achieve the goal, the theory of "redundant connections" was used, and the design scheme of the hydraulic machine was analyzed. On the results of the conducted analysis, several possible schemes for the extraction of "redundant connections" were developed, and the calculation was carried out. From the proposed schemes, the most appropriate scheme for creating a gear-type hydraulic machine was determined - a scheme using the central load of the driving gear and a barrel-shaped profile of the longitudinal contour of the tooth of the driven gear. The paper also considers additional benefits arising from the removal of redundant connections. On the basis of the developed diagram of the action of forces in gear engagement, it is shown how deviations from the geometric accuracy of the gear affect the operation of the hydraulic machine and why the proposed scheme with a barrel-shaped profile of the longitudinal contour of the tooth is more appropriate. Among the important results of the research should be attributed the synthesized perspective scheme of design of a gear hydraulic machine. The use of the proposed scheme will allow the reduction of redundant connections (from 7 to 5, relative to the conventional scheme), which will contribute to the reduction of additional deformations and energy losses when working in the hydraulic motor mode and fluid losses when working in the hydraulic pump mode. And the implementation of one of the coupled gears with a barrel-shaped longitudinal profile of the teeth will ensure the stabilization of the displacement moment when the unit is operating in the hydraulic motor mode and will stabilize the hydraulic efficiency parameter when operating in the pump mode.

Published: August 2023

La pesquisa y derivación temprana del trastorno del espectro autista (TEA) son claves para potenciar el desarrollo de los niños afectados. Recientemente se promulgó una ley que indica realizar tamizaje de TEA en las prestaciones de salud. Esto representa un desafío para los profesionales de pediatría ambulatoria. El objetivo es revisar la utilidad en el tamizaje de TEA, de cuestionarios y escalas validadas en Chile para el screening del desarrollo psicomotor, desarrollo socio-emocional y cribado específico de TEA. El screening del desarrollo psicomotor evalúa el desempeño general desde edades tempranas, dando las primeras señales de retraso, con mayor probabilidad de que se trate de TEA si hay compromiso de los dominios social y lenguaje. Los cuestionarios socio-emocionales pueden ser aplicados precozmente, entre sus ítems se incorporaron preguntas de señales de TEA, pero no se usan rutinariamente en atención pediátrica. Las escalas específicas de screening de TEA validadas en Chile son Cuestionario Modificado de Detección del Autismo en Niños y Niñas Pequeños (M-CHAT), Quantitative Checklist for Autism in Toddlers Q-CHAT (Q-CHAT) y el Examen del Estado Mental para Autismo (AMSE), para lactantes mayores de 15/18 meses, con propiedades psicométricas prometedoras. Se recomienda complementar la observación clínica con pruebas generales para el tamizaje del desarrollo psicomotor, desarrollo socio-emocional y escalas específicas para el screening de TEA, en forma seriada en la infancia. La implementación de cuestionarios en línea permite optimiza su cobertura e interpretación. Independiente del dominio afectado, es importante realizar un seguimiento y comenzar con intervención temprana, mientras se realiza la confirmación diagnóstica.

The article proposes an author's approach to defining the essence of an integrated quality management system and strategic management as a set of elements of the organizational structure, processes and resources necessary for the implementation of a continuous multidimensional process of active management influence on all elements that make up the system, aimed at improving the abilities and unique competencies that provide development in the direction indicated in the mission and goals, taking into account external factors leading to a long-term increase in the level of performance and efficiency of activities, focused on meeting the requirements of all stakeholders and continuous improvement of activities, taking into account regular adjustments to plans. Unlike existing definitions based on classical management methodology, the author's approach takes into account the trends in the integration of related management areas – quality management and strategic management – to achieve a synergistic effect. The development of the methodological position of the integrated quality management system and strategic management, including principles, approaches, methods, algorithm, will contribute to the creation of a multifunctional management system, with a single mission and policy, in which all key elements of activity work in a comprehensive manner, resources are optimally used, and the requirements of all interested parties are taken into account. sides. A system of element-byelement integration has been developed that allows taking into account the features of each process of strategic management and quality management and is focused on the principles and main provisions set forth in ISO 9001:2015 standards. The model links the main stages of strategic management and quality management processes to management functions (planning, organization, motivation and control), and takes into account the main organizational measures. A formalized approach to describing an integrated system creates a base in the form of an interconnected sequence of quality management and strategic management processes for further theoretical studies of integration (principles, features, conditions) and implementation practices (means, methods, tools).

This article examines the impact of digital platforms on the creation of innovative business models for SMEs. The aim is to identify intermediary mechanisms for reconfiguring the capabilities of digital platforms to foster innovative SME business models. The paper provides an analysis of various definitions of "digital platform" and argues that these platforms are based on algorithmic mechanisms, mutual benefit among stakeholders, a unified information environment, and the effect of reducing transaction costs. It interprets a digital platform for entrepreneurship as an information and communication system aimed at supporting entrepreneurial activities and providing diverse tools, services, and opportunities for entrepreneurs to facilitate the launch, management, and development of their businesses. The article explores the peculiarities of traditional business models (such as direct product sales, franchising, advertising-based models, etc.) and their potential transformation into modern business models (digital platforms, subscription economy model, content subscription model, etc.). The key characteristics of a digital platform for entrepreneurship are identified, including e-commerce, marketplaces, analytics and management tools, community and network utilization, and integration with other services. The study investigates intermediary mechanisms for reconfiguring SME business models, defining these processes as ways for digital platforms to coordinate interactions among various economic participants. It establishes that digital platforms can offer SMEs a range of intermediary mechanisms, including marketing, operational, financial, and informational mechanisms. Furthermore, the paper substantiates the possibilities of reconfiguring traditional SME business models and transforming them into contemporary ones through the reconfiguration of capabilities, value chain innovations, access to new markets, and process digitization.

The article analyzes the state of the tourist and hotel-restaurant business in the Ivano-Frankivsk region in the condition of the war. Considering the relative safety of the territory, Ivano-Frankivsk is a shelter for internally displaced persons, relocated businesses. Despite the difficult military situation in the country, there are relatively positive indicators of the development of the hotel and restaurant business. This is due to the fact that people fleeing the war from the occupied territories fled to safe regions of Ukraine, in particular, to Ivano-Frankivsk region. Accordingly, they rented housing and visited restaurants Tourism is one of the most vulnerable sectors of the economy, which suffered greatly from russia's war against Ukraine. At the same time, the hospitality industry is very flexible and has had to adapt quickly to all the challenges faced during the war. Ivano-Frankivsk region has a strong potential for the development of domestic tourism, which is now being particularly emphasize. Local accommodation and catering establishments have been supporting war victims since the first days of the war. But the fact remains that, as in the entire territory of Ukraine, the war had an extremely negative impact on the activities of travel firms specializing in international tourism. Tourism is an important component not only for supporting the economy of the country in the rear, but also very strong element of the psychological recovery of people in the conditions of the war. Despite the difficulties, steps are being taken in the development of tourism, tourist routes are being developed, and projects aimed at supporting small businesses in the field of hospitality are being implemented. A significant number of tourism activities are carried out to support internally displaced persons in order to help them adapt to a new place. These include excursions, fairs, tours of a patriotic nature and the organization of rest in recreational areas of the region. On today's difficult day, this is the only correct support for Ukraine to defeat the enemy. With proper organization and support of the hotel, restaurant and tourist business, Ivano-Frankivsk region will be able to represent Ukraine in the tourist arena after the victory.

Published: August 2023

The key points of the financial activity of small business development are justified. It is noted that entrepreneurship in the field of small business is determined by the activity of business entities, which is characterized by both features that are characteristic of business structures in general, and specific features that determine the peculiarities of such functioning of business entities in the sphere of the implementation of business tasks and goals. It was determined that the success of small business is determined by the conditions of the environment in which business structures function. It is clarified that such conditions should include economic, legal, socio-cultural, demographic, technological, natural-geographic and organizational conditions. It has been proven that ensuring the existence of all enterprises depends on its financial resources. The sources of formation of financial resources are the main feature of their classification. In practice, own and involved groups of sources of formation are distinguished. FG "Iryna – O.T" was chosen to evaluate the structure of sources of small enterprises. This is a farm, the main activity of which is grain and technical crops. During the studied period, the amount of financial resources is increasing. Having evaluated the financial management of the FG "Iryna – O.T" using various indicators, we came to the conclusion that the FG under study is profitable and financially independent. Having evaluated the formation, placement and efficiency of the use of financial resources, they came to the conclusion that the FG "Iryna – O.T" had a good financial condition, as evidenced by the relevant indicators: the amount of net profit increased by 469.8 thousand hryvnias; liquidity indicators of the FG indicate the liquid balance of the enterprise; the state of the FG in 2020–2022 is characterized as financially stable; the financial independence of the FG is high, which indicates a good state of financial resources; profitability indicators of FG had positive values. In general, FG "Iryna – O.T" has positive indicators of filling financial resources, their volume increases over the years, however, the FG has become completely independent of obligations and avoids a crisis situation associated with a lack of funds to pay debts. Farms are an important component of the market of economic relations between the world and Ukraine. In the conditions of hostilities, farmers and private peasant farms provided food for the local population and internally displaced persons, thus proving the stability and possibility of ensuring the existence of small producers.

Published: August 2023

The author found out in the article that the hospitality industry is a collective concept due to the fact that it covers various forms of activity in the field of services, maintenance, tourism and transport business, recreation industry, etc. It is noted that most scientists define hospitality as a set of industries that provide services to travelers during their immediate stay outside their permanent residence. The author emphasized that the market of tourist services and entertainment is of particular importance for the development of the hospitality industry in the Dnipropetrovsk region because the attraction of foreign tourists to the industry segments of this region is a key factor in the development of this area. It was found that the Dnipropetrovsk region has almost the same number of two-, three- and four-star hotels, as well as a small number of high-class hotels. Moreover, the medium-level service segment is represented by a sufficient number of establishments. A special stage in the hospitality industry of Dnipropetrovsk region began in February 2022, when there was a complete reorientation of many entities to ensure the basic values and needs of refugees and people forced to evacuate from regions of active hostilities. The modern hospitality industry of the Dnipropetrovsk region has its own specifics and functions under the influence of various factors. Characteristic features of the hotel sphere of the region are the presence of harmonious relationships with other spheres of the tourism industry, the social nature of hotel activity, the complexity of the hotel product due to their modification for individual needs, the personification of customer service, the specific variety of types of hospitality, reception and service of tourists. The prospects for the development of the hotel sector of the Dnipropetrovsk region are associated with an increase in the number of certified hotel enterprises of the budget price category and the further introduction of information and communication technologies in the hotel and tourism spheres of the region, which will meet world standards for the development of advanced technologies, improve existing hotel and tourist services, and create new ones.

Authors: Saiful Fazad Adiela , Nasir Muhammad Amir , Noor Noramaliza Mohd  Noor
Published: August 2023

Blood irradiation is done to sterilize and cease donor T-lymphocytes functionality to avoid Transfusion Associated-Graft Versus Host Disease (TA-GVHD). Dose mapping is the primary means of ensuring that the irradiation process is being conducted correctly. The aim of this study is to measure the minimum, maximum and central absorbed gamma radiation dose delivered at the newly customized blood equivalent phantom using a Gafchromic EBT-XD film. A Gammacell 3000 Elan Blood Irradiator with Cesium-137 source was used. To obtain the dose calibration curves, the films were placed at the center of a phantom and irradiated with the dose range from 5 Gy to 35 Gy with one unirradiated film as a control. The dose calibration curve was plotted using red, green and blue channels. While, for the dose mapping measurement, the irradiation exposure of 9.03 minutes was used to deliver a central dose of 25 Gy to the film. The response of the film will be compared with the GC Dose Mapping Report 2022 which used a water equivalent medium as a phantom. For the calibration curve, the red channel of the film was utilized in this study as it had a higher signal than the other channel. The doses obtained at central, minimum and maximum using EBT-XD film with customized blood equivalent phantom were in agreement with that obtained from GC Dose Mapping Report 2022 to be within ±7.6%, ±8.51% and ±9.95% respectively. We concluded that the customized blood equivalent phantom together with EBT-XD film has a potential to map the dose in blood irradiator accurately. The doses obtained from EBT-XD film were in the range of doses needed to inhibit the proliferation of the T-lymphocytes with central, minimum and maximum doses were 26.9 Gy, 17.2 Gy and 35.7 Gy respectively.

The results of observations and studies of autochthonous Don varieties in 2022 at the Don ampelographic collection named after Ya.I. Potapenko (Novocherkassk, Rostov region). Varieties were studied in grafted, covered culture. The object of research were 20 grapevine varieties of different directions of use and maturation. Most of the studied varieties (80 %) had more than 60 % bud break. The percentage of fruit bearing shoots varied over a wide range, from 26.8 % (Krestovsky) to 93.1 % (Durman). The highest average bunch weight had varieties − Krestovsky (456 g) and Kumshatsky Belyj (429 g). The yield varied from 1.9 kg/bush (Krestovsky) to 11.4−11.6 kg/bush (Silnyak and Shilohvosty). Most of the studied varieties (11 out of 20) had a high or very high calculated yield (from 130 c/ha and more). Very high sugar content in berry juice had 3 varieties (Krasnostop Zolotovsky, Shampanchik Tsimlyansky and Varyushkin), 5 varieties had high sugar content, 9 − medium, 2 − low and 1 had very low. One variety − Shampanchik-2 had a very high titratable acidity (15.8 g/dm3). High titratable acidity was noted in 4 varieties, the majority of varieties (55 %) had an average titratable acidity (from 7 to 9 g/dm3). According to the results of the studies, it can be tentatively identified that technical and universal varieties with white berries: Bessergenevsky-10, Kosorotovsky, Durman, Kumshatsky Belyj, Sibirkovyj, and variety with colored berries – Varyushkin are promising in terms of yield and quality of grapes for winemaking. These varieties are of early-middle and medium-late ripening, which is very important for the zone of the northern industrial viticulture of the Russian Federation. Research in this direction will be continued.

The article presents the research results on the degree of favorability of agro-ecological conditions of Sevastopol for grapevine cultivation. The analysis according to the available multi-year data of weather stations of the Crimean peninsula is given. The following climatic indices characterizing vegetation period and grape ripening period were calculated: sum of temperatures above 20°C, ratio of sum of temperatures above 20 °C to sum of temperatures above 10 °C, Huglin and Winkler indices, average temperature of vegetation period, Selyaninov hydrothermal coefficient, sum of precipitation per year and vegetation period. Besides, the main agro-ecological factors limiting the possibility and efficiency of grapevine cultivation were considered: average of absolute minima of air temperature and sum of active temperatures above 10 °С. A digital complex map of the spatial distribution of these indices on the analyzed territory was constructed by means of geoinformation modeling. The distribution of Sevastopol territories that are not suitable for vineyards establishment was analyzed: with unfavorable soil conditions, with a height of more than 600 m above sea level, with a slope of over 20 degrees, as well as lands of forest and reserve funds. As a result of a comprehensive analysis of agro-ecological conditions in the territory of Sevastopol 9 ampeloecotopes were identified. According to the results of the comparison of agro-ecological conditions of the selected ampeloecotopes with the requirements of grapevine varieties to growing conditions, taking into account the dependence of the quality indicators of viticulture and winemaking products on agro-ecological factors, recommendations for agroecological optimization of the varietal composition and terroir specialization of the viticulture and winemaking industry in the territory of the city of federal significance − Sevastopol were developed.

The results of the technological assessment of white Dagestan native technical grapevine varieties growing on the institute's ampelographic collection are presented: Gok Isum, Ghara Bakhin Tsibil, Latsu Kere, Hotsa Tsibil, from which natural table wine samples were prepared using classical technology. The studies were carried out in the laboratory of ampelography and technological evaluation of grapevine varieties in microwinemaking conditions. The mass of each batch of grapes was 10−20 kg. The main physical and chemical indicators of grapes, as well as glucoacidometric indicator and indicator of technical maturity, were determined. In the prepared samples of wines, chemical indicators were determined; an organoleptic assessment was carried out. Italian Riesling was taken as a control variety, which is included in the State Register of Breeding achievments approved for use in the Russian Federation. Based on the results of three years testing, conclusions were made about the feasibility of using varieties: Gok raisin, Ghara bakhin tsibil, Latsu kere, Hotsa tsibil in the production of dry high-quality white wines (tasting score 8.6−8.7 points)
Beyond the Ballot Box: Sexual Harassment and Legislative Accountability in Canadian Politics
Authors: Raney Tracey , McGregor R. Michael
Published: August 2023

Since the #MeToo movement, several countries have taken steps to address sexual harassment in politics (for example, the United States, United Kingdom and Canada). While researchers have evaluated the electability of candidates accused of sexual harassment, less is known about what the public thinks should happen when elected officials engage in this behaviour. Utilizing an innovative module from the 2019 Canadian Election Study, we assess the steps voters believe legislatures should take when an MP sexually harasses someone. Our results demonstrate that a vast majority of the public believes that MPs should face consequences when they commit sexual harassment, including potential removal from office. We also find that women are more likely than men to believe MPs should be punished when they are accused of sexual harassment. These findings have relevance for legislatures globally, revealing the importance of transparent, independent processes to address harassment and violence in the political sphere.
Democracy During #MeToo: Taking Stock of Violence Against Women in Canadian Politics

One hundred years after some Canadian women were given the federal franchise, women remain significantly underrepresented in every legislature across Canada. Indigenous, racialized, and young women face additional barriers to participation and are underrepresented far beyond their numbers in the population. While barriers to participation are broad and pervasive, sexual harassment and violence against women in politics - whether in the form of direct threats, implied threats, violent symbolic images, and physical violence - play a significant role in limiting women’s political participation.

This report presents non-partisan, evidence-based research on how governments, legislatures, civil society, and non-governmental organizations have addressed the problem of violence against women in politics both within and beyond Canada. The data included in the report draw from extensive Canadian and global research and a select number of interviews with current and former women politicians from across the political spectrum who have bravely spoken out about their experiences of sexual harassment and violence in Canadian politics.

The report’s goals are to: (1) enhance public policy discussions on how to combat gender-based violence in Canadian politics and (2) raise awareness about this issue amongst decision-makers and the Canadian public.

Current strategies, policies, and legislation from eight countries and eight civil society organizations are included here. These include the world’s first law explicitly and specifically criminalizing violence against women in politics (Bolivia, with similar models adopted in Costa Rica and Mexico). The recently adopted (July 2018) Grievance Scheme in the United Kingdom and the new law adopted (December 2018) by the United States Congress to address sexual harassment are also included, as are recent discussions and changes within the United Nations and European Parliament.

Although Canada had taken some steps to address this issue in the past, in the #MeToo era equal and full participation in the democratic process demand further concrete action to solve the problem of violence against women in Canadian politics once and for all. This report offers 12 recommendations for governments, legislatures, political parties, and media, all of which, we believe, have a role to play in combatting this fundamental issue for Canadian democracy and gender equity in politics.

This study aims at assessing the quality of sachet water sold in Gashua, Bade L.G.A. of Yobe State, Nigeria. Sachet water were obtained from five different factories, named: A, B, C, D and E. Heavy metals’ concentrations were analysed using Atomic Absorption Spectrophotometry and standard analytical procedures were used to assay for the physicochemical parameters. The results obtained from this study revealed that the concentrations of lead (0.12± 0.01, 0.12± 0.01, 0.18± 0.01, 0.05± 0.01 and 0.13± 0.01), cadmium (0.01±0.01, 0.02±0.01, 0.02±0.01, 0.03±0.01, 0.03±0.01) and arsenic (0.11±0.00, 0.14±0.01, 0.22±0.00, 0.09±0.01, 0.13±0.01) for samples A, B, C, D and E were significantly higher than the WHO permissible values of 0.02+0.00, 0.003+0.00 and 0.01±0.00 respectively. Zinc was not detected in any of the samples but iron was detected at significantly lower value of 0.002±0.00, 0.03±0.01, 0.05±0.01, 0.03±0.00 and 0.03±0.00 for samples of A, B, C, D and E respectively, when compared with the WHO standard value of 3.00±0.00. Chromium showed higher concentration in samples A, C and E but samples B and C fall within the WHO permissible limit of 0.05±0.00. Conductivity, TDS and sulphate for samples A, B, C, D and E were seen to be significantly lower than the WHO standard value. Turbidity and total suspended solids were found to be above the WHO limit. In conclusion, the results of this study have shown that some metals of the various branded sachet water do not meet the recommended standard due to high concentration of heavy metals and physicochemical parameters beyond...
