Published: November 2022

За последнее десятилетие значительно увеличилось число методов машинного обучения, а также областей их применения и подходов в связи с необходимостью разработки более точных и надежных моделей прогнозирования. Рассмотрен подход прогнозирования параметров электромагнитного поля на основе распределенной среды Apache Spark Streaming. Первоначально данные с различных датчиков электромагнитного поля в реальном времени обрабатываются до уровня структурированных данных, являющихся входными данными в модели прогнозирования, которая фокусируется на прогнозировании типа значения с учетом нескольких классов. Кроме того, для повышения эффективности прогнозирования был использован метод регуляризации для выбора признаков, чтобы уменьшить переобучение. Описанная архитектура представляет собой интеграцию Apache Kafka, Spark и Cassandra и рекомендуется к применению для прикладного мониторинга и прогнозирования состояния систем различного профиля. Экспериментальный анализ показывает, что использование метода регуляризации повышает эффективность рекуррентной нейронной сети при прогнозировании параметров электромагнитного поля. Предложенная модель способна эффективно использовать смешанные прикладные данные, уменьшает вероятность переобучения модели и снижает вычислительные затраты

Over the past decade, the number of machine learning methods, as well as their areas of application and approaches, has increased significantly due to the need to develop more accurate and reliable forecasting models. An approach to predicting the parameters of an electromagnetic field based on the Apache Spark Streaming distributed environment is considered. Initially, data from various real-time electromagnetic field sensors are processed to the level of structured data, which is the input to the prediction model, which focuses on predicting the type of value given several classes. In addition, in order to improve the prediction performance, a regularization method was used for feature selection to reduce overfitting. The described architecture is an integration of Apache Kafka, Spark and Cassandra and is recommended for application monitoring and predicting the state of systems of various profiles. Experimental analysis shows that the use of the regularization method increases the efficiency of the recurrent neural network in predicting the parameters of the electromagnetic field. The proposed model is able to effectively use mixed applied data, reduces the likelihood of model overfitting and reduces computational costs

Based on the analysis of the current state of existing agricultural cooperatives within the country and their features in Lviv region, main problems of development of this organizational and legal form have been identified. It is established that the functioning of agricultural cooperatives in Lviv region is still in its infancy due to imperfect institutional environment and their production and economic results do not have a significant impact on the overall economic condition of the agricultural sector and the welfare of the rural citizens.
Dynamics of registered cooperatives in Ukraine is compared with the actual ones. It is shown that the development of cooperative process is made due to changes to general socio-economic situation in the industry, which is facilitated by state authorities, as well as development of the latest forms and methods of organizing economic activity in rural areas, implemented on a project basis.
Conclusions are made that creation and functioning of cooperatives is the result of institutional changes, and cooperative organizational forms can be considered as a certain social capital. It is established that the main problems of agricultural cooperation development in Ukraine are: incomplete restructuring of the agricultural sector, weak material and technical base of cooperatives, especially in capital-intensive areas of agricultural production, unavailability of loans and weak financial support of agricultural cooperation by the state.
It is shown that the state policy should be aimed at creating conditions for the development of agricultural cooperatives, intensification of cooperatives, state support and legal protection of cooperatives, optimization of tax policy by differentiating tax rates and facilitating access to credit for agricultural cooperatives. rural households.
It is recommended in further research to pay attention to the elimination of identified obstacles, primarily of an institutional nature, in accelerating the development of agricultural cooperatives as an organizational and legal form that has significant potential for its development.

Published: November 2022

Most enterprises in the construction industry are characterized by inefficient use of anti-crisis potential. Therefore, the task of assessing the possibility of crises and the feasibility of rehabilitation of construction companies does not lose its relevance.
Key indicators have been identified that can be used to assess the feasibility of a set of measures to rehabilitate an enterprise (for example, a small construction contractor), the loss of economic stability of a small construction enterprise using discriminant analysis. The most important economic indicators were the factors that form four groups: liquidity ratios, profitability indicators, indicators of financial independence, indicators of business activity of the enterprise. An appropriate model has been created that allows to predict with sufficient accuracy the possibility of bankruptcy or liquidation of the enterprise. The main indicators for assessing the anti-crisis potential of a construction company are identified, the task of which is to reduce the likelihood of crisis situations, prevent loss of solvency and ensure the effective functioning of the enterprise. The main indicators that can serve to determine the possibility of measures to rehabilitate a construction company or determine its anti-crisis potential are the concentration of borrowed funds, profitability of operating activities, the ratio of increments of accounts payable and receivable, mobility and asset turnover. The use of the proposed approach to determining the anti-crisis potential, allows you to develop a set of recommended measures in the rehabilitation of construction companies aimed at improving their financial and economic condition, namely: financial, economic, social, organizational, technological, legal and other measures aimed primarily at improving the financial condition of the debtor, as well as satisfaction in full or in part of creditors' claims.
Key words: bankruptcy, sanitation, insolvency, economic stability, anti-crisis potential, small construction enterprises, construction enterprises, crisis forecasting, economic security of the enterprise.

The conventional protection schemes may lead towards the inadvertent operation of the protection devices with the increased penetration of renewable energy sources based distributed generation (RES-DG) in distribution networks (DN). The miscoordination and the malfunctioning of directional overcurrent relays (DOCR) may occur due to significant change in the fault current level (FCL) and the change in the network topology form the radial to ring topology caused by the RES-DG. Optimization algorithms (OA) and modification in relay characteristics were mostly used to tackle the DOCR miscoordination problem. However, in this paper, a fast and an accurate protection coordination scheme is proposed to eliminate the DOCR miscoordination and to reduce the overall operation time of DOCRs by employing an advance optimization algorithm along with an innovative modification in the relay characteristics. In the first step, time-current characteristics (TCC) of the conventional DOCR are modified to a hybrid time-current-voltage (TCV) characteristics by including the effect of the fault voltage in the relay characteristics equation. Thereafter, the performance of conventional Harris Hawk’s optimization (HHO) is enhanced with an improvement in the exploration strength of the HHO by an adaptive mutation-selection of the alpha hawks during each iteration named as alpha-HHO (α-HHO). The protection coordination problem is formulated as a non-linear constrained optimization problem. The proposed protection scheme is evaluated on the IEEE-8 bus meshed DN. The standard IEEE-8 bus test system is modified by integrating multiple squirrel cage induction generators and PV-based RES-DGs at optimal bus locations. Detailed numerical studies are carried out with the help of simulations to show the performance of the proposed scheme. The results are compared with the existing protection schemes reported in recent literature. The investigation results show that the highest reduction in overall relay operating time with zero mis-coordination is achieved with the proposed scheme.

Excess and shortage of some metal ions like Fe3+ ions in drinking water away from permissible levels can cause severe health threat. Similarly, chromium is found chiefly in a hexavalent form that also poses a threat to human health. Human beings and other living organisms are at greater risk of exposure to these toxic ions and other chemicals. Development of new, effective and fast sensors is the need of time. MOFs are nanoporous materials which have quite fast detection time and effective in sensing of various metal ions and hazardous chemicals. A Zn based two-dimensional is synthesized and applied for the sensing of Fe3+ and Cr2O72- ions. Due to the presence of free oxygen and nitrogen atoms, this MOF showed quite high sensitivity with Ksv value of 1.8×104 and 6.5×104 with a limit of detection (LOD) 2.5μM and 0.15μM for Fe3+ and Cr2O72-ions respectively. This study proved the two-dimensional MOF as excellent sensor for the detection of Fe3+ and Cr2O72- ions. This can be used as colorimetric sensor for these ions due to color changes visible to the naked eye.

Solar thermal collectors such as flat plate and evacuated tube collectors are used for maximum of 60-80 ℃ temperature and parabolic trough collectors are used for 700-900 ℃ temperature ranges. It is needed to develop and analyse solar collector, such as compound parabolic collectors (CPC) which can operate for intermediate temperature range from 50-300 ℃ for industrial and domestic applications. However, optical and thermal performance of CPC is strongly influenced by concentration ratio. The current study presents a comparative optical and thermal analysis of CPC with fixed (4.58) and variable (4.58 to 5.87) concentration ratio by using model-based transient simulation approach. Two profiles of compound parabolic collector are analysed with fixed and variable concentration ratio for the subtropical climate of Taxila, Pakistan. 2D profiles of both collectors are modelled and designed in MATLAB and are then analysed optically by using Monte Carlo ray tracing technique through TracePro. In addition, thermal analysis of both profiles is also performed through ANSYS. The resulted optical efficiency with fixed and variable concentration is 91 % and 96 %, respectively at a given tilt angle. Whereas maximum temperature achieved with both profiles is 5°C and 7°C, respectively. Thus, it is concluded that performance of CPC with variable concentration ratio is much better compared to fixed value.

The biggest problem faced by the world these days is pure drinkable water, and in a few years, pure drinkable water will not be easily available, as it is becoming brackish and saline due to pollution. By using solar energy, a solar still can produce pure water which can be used for drinking, cooking, and also for industrial purposes. In this research, a solar still based on clean technology using solar energy to drive the system is used that can be operated easily and with an approximately negligible maintenance cost. A pyramid solar water desalination unit with modification of the solar electric water heater (used to increase water temperature) is developed to increase the water yield per day. A theoretical model of the solar still unit is developed and performance is evaluated. Based on this theoretical design, fabrication is carried out and experiments are performed to predict the overall output. It is observed that the output distilled water has a total dissolved salts value much lower than the total dissolved salts of groundwater. Additionally, the average output of a solar water desalination unit with an electric water heater is found to be enhanced compared with the unit without an electric water heater.

Technological advancements in solar power systems necessitate highly reliable power inverters with high efficiency and small size. An LLC resonant converter-based pseudo-Direct Current (DC) link inverters offer these qualities to some extent. The resonant circuits of conventional pseudo-DC link inverters cannot attain a zero gain and cannot handle variable frequency control which in turn requires very large filters to produce pure sinusoidal output voltages for the grid. The usage of these filters consequences in the enhanced price and size of inverters; moreover, the reliability of inverters is also reduced. We propose a novel topology for a pseudo-DC link inverter based on an LLCLC resonant converter. The proposed inverter does not require large filters, because it generates rectified sinusoidal output voltages. An additional parallel LC component is added in series to the resonant circuit, which makes it able to attain a zero gain through an infinite circuit impedance. The 400 W pseudo-DC link inverter with a 40 V input and a 400 V output is designed and simulated on OrCAD PSpice software. The results showed that there is a significant improvement in achieving a zero gain. The possible lowest gain achieved is approximately 0.125. The proposed technique claimed to be more efficient than those formerly used, subsequently contributing to satisfying outcomes.

Authors: Rawat Ramu , Tirkey Noli Nivedita
Published: November 2022

Female genital mutilation (FGM) practice is unhygienic and unhealthy traditional practices which have affected girls and women’s health adversely for all-time, and such practice is prevalent in many African countries. This study intended to examine factors associated with the FGM prevalence, attitudes toward the discontinuation of the practice, and consequences of FGM practice on reproductive health in terms of sexual transmitted infections/symptoms (STIs/STSs) among women of reproductive ages in Senegal. To fulfill the study objective on factors associated the prevalence of FGM and attitudes toward the continuation of FGM practice, the 2019 Senegal Demographic Health Survey (DHS) data sets were used based on binary logit and multinomial logit regression models. The results show that rural areas, married women, women of Muslim religion, Poular women, women of lower education and lower wealth, and women who were never exposed to social media reported a higher prevalence rate of FGM and were more likely to support continuation of FGM practice. To fulfill the research goal on consequences of FGM practice on STIs/STSs, the 2010 – 2011 DHS was employed because the 2019 DHS did not collect data on STIs/STSs. FGM practice was associated with lower knowledge about STIs/STSs and higher prevalence of STIs/STSs. Our findings suggest that education promotion, poverty reduction, rural development, and dissemination of the adverse consequences of FGM practice could help reduce FGM practices. These findings could have important implications for achieving the sustainable development goals.

Yerli nəqliyyatın və qarşıdan gələn avtomobillərin maneçiliyi olmayan, uzaq məsafələrə böyük sürətlə intensiv sərnişin və yük daşımaları üçün nəzərdə tutulan yollara avtomobil magistralları (avtoban) deyilir.
İlk avtoban (avtomagistral) 21sentyabr 1924-cü ildə tikilmiş, İtaliyanın Milan və Vareze şəhərlərini birləşdirən,Avropada ümumi istifadəli ilk sürətli yol hesab edilir.Yolun uzunluğu 43km, eni 11-14m, maksimum uzunluq mailliyi 30‰ təşkil edirdi, gündə 1000 avtomobilin hərəkətinə hesablanmışdı.İlk illərdə yol səhər saat 6-dan gecə saat 1-ə qədər açıq olurdu.
Uzunluğu 20 km olan ilk alman avtobanı (Köln-Bonn magistralı) 1932-ci ildə inşa edilibdir. 1933-cü ildə avtoban tikintisi Almaniyada dövlət proqramı elan edilmişdi.
İkinci Dünya müharibəsindən sonra Fransada və Böyük Britaniyada avtomagistralların kütləvi tikintisinə başlanıldı.
XXəsrin ortalarında ABŞ-da avtomagistralların(highway)aktiv tikintisinə başlanıldı. XXIəsrin başlanğıcında Çin Xalq Respublikası avtomagistralların tikilməsi tempinə və uzunluqlarına görə digər ölkələri arxada qoydu və 2021-ci ildə dünyada birinci yeri tutdu.
İlk sovet “avtobanının”(Moskva-Minsk) layihəsi 1935-ci ildə işlənildi.Yolun tikilməsində QULAQ məhbuslarından istifadənin və yerli sakinlərin işə pulsuz cəlb olunmasının nəticəsində iişin smeta dəyərini xeyli azaltmaq mümkün oldu. 1936-cı ildə ilk iki sovet avtomagistralının (Moskva-Minsk və Moskva- Kiyev) tikintisinin başlanmasına əmr verildi.
Ulu öndər Heydər Əliyevin təşəbbüsü ilə 1998-ci ilin sentyabrında Bakıda “Tarixi İpək yolu”nun bərpasına dair beynəlxalq TRASEKA konfransın proqramı çərçivəsində ölkəmizdə yol infrastrukturunun inkişafında mühüm işlər görülməyə başlanıldı.Müasir zamanda ölkəmizin yol şəbəkəsində mühüm yer tutan 8 magistral avtomobil yolunun (M1-M8) ümumi uzunluğu 1774 km təşkil edir. Bu yolların bəzilərinin istiqaməti Böyük İpək yolunun istiqamətinə uyğundur.
Magistral avtomobil yollarının layihələndirilməsində və tikilməsində həllini gözləyən bir çox problemli məsələlər mövcuddur.

Geoloji modelləşdirmə əsasən geoloji cismin həndəsi modelinin səpələnmiş geoloji məlumatlar əsasında necə çıxarıldığını öyrənir. Nümunələrdən götürülmüş geoloji məlumatlar 3 əsas xarakteristikaya malikdir: çox mənbəli, səpələnmiş və qeyri-bərabər. Naməlum bölgələrdə bir modelin paylanma trendini çıxarmaq və proqnozlaşdırmaq üçün məhdud sayda nümunələrin məlumatlarından istifadə etmək böyük bir problemdir və müvafiq modelləşdirmə nəticələri də daha çox qeyri-müəyyənliyə malikdir. Etibarlı üçölçülü geoloji modelin (xüsusilə süxur hissəcikləri modeli) yaradılması mineral ehtiyatların, palçıq vulkan və rezervlərin hesablanması və mədən işlərinin layihələndirilməsi üçün mühüm əhəmiyyət kəsb edir.

Published: November 2022

The paper is devoted to design of 3D model of the study area by use of attribute analysis of 3D seismic data applied to study the geology of Naftalan oil field in more detail. The field is located in Naftalan-North Naftalan area of Ganja Oil and Gas Province, Yevlakh-Aghjabadi depression.
The paper expounds the data on Naftalan field considered an ancient brachianticline type of field in Azerbaijan. The history of study of the field using geological and geophysical techniques has been briefly given. Geological evaluation of the cube derived by processing of 3D seismic data acquired in Naftalan area in 2012 made it possible to outline a confidently traced interval reflecting the foot of Horizon I of Maykop.
Through selection of areas featured by variation of wavefield characteristics, we have calculated several attributes in this interval and analyzed the acquired results gaining more accurate seismic data and confident tracing of seismic horizons. To avoid repetition, some poorly informative attributes or attributes providing similar results have not been applied in further studies.
Our study aims to define attributes (RMS amplitude (Root mean square), Variance/Edge method, Relative Acoustic Impedance) that are more effective for outlining disjunctive dislocations of various amplitude and can be applied for 3D model design of the geology of study area. Processing results of all 3D data have been given in form of cubes of seismic attributes. Further analysis of these attribute cubes enables us to study the geological setting of the foot of Horizon I of Maykop and select the most effective attributes. As a result, the 3D model of the study area for seismic horizon reflecting the foot of Horizon I of Maykop has been designed.

Laboratoriya fəaliyyətində ən əsas prioritet məsələ pasiyent təhlükəsizliyi üçün keyfiyyət idarəetmə sisteminin təkmilləşdirilməsidir. Səhiyyənin keyfiyyəti mövcud bilik və texniki inkişaf səviyyəsi ilə bağlı göstərilən səhiyyə xidmətinin mükəmməllik həddi ilə sıx bağlıdır. Akkreditasiya laboratoriyanın səriştəsini nümayiş etdirməyin effektiv üsuludur. Laboratoriyaları ölkə və dünya miqyasında tanınması, keyfiyyətin saxlanılması və təkmilləşdirilməsinin stimullaşdırılması üçün ən ideal vasitədir. Beynəlxalq Kliniki Kimya və Tibbi Laboratoriya Federasiyası (IFCC) və Avropa Kliniki Kimya və Tibbi Laboratoriya Federasoyası (EFLM) ISO standartlarına əsaslanan laboratoriyaların akkreditasiyasına diqqət yetirmək və Avropa Akkreditasiya və milli akkreditasiya orqanları ilə əməkdaşlıq daxildir.
Məqalənin yazılmasında məqsəd tibbi laboratoriyaların akkreditasiyasının əhəmiyyətini aktuallaşdırmaq və daha çox tibbi laboratoriyaların akkreditasiyaya cəlb edilməsini təmin etməkdir. Hal-hazırda Azərbaycanda fəaliyyət göstərən akkreditasiyadan keçmiş tibbi laboratoriyalar azlıq təşkil edir. Odur ki, laboratoriyaların beynəlxalq standartların tələblərinə uyğun olaraq fəaliyyət göstərməsi onların işinin yaxşılaşdırılması, xidmət sahələrində keyfiyyətin maksimum dərəcədə artırılmasına birbaşa təsir edəcəkdir.
Tibbi laboratoriya xidmətləri bütün xəstələrin və bu xəstələrin qayğısına qalmaq üçün məsul olan bütün klinik personalın ehtiyac və gözləntilərinə cavab verir. Tibbi laboratoriya tədqiqatlarında təhlükəsizliklə bağlı və təhlillərlə yanaşı, istəklərin formalaşdırılması, xəstənin hazırlanması və açıqlanması, klinik nümunələrin toplanması, daşınması, saxlanması, emalı və təhlili, habelə validasiya, şərh, hesabat, və tövsiyələri özündə cəmləşdirir.
Milli qaydalarla icazə verilməsi tələb olunsa da, tibbi laboratoriya xidmətləri çərçivəsində konsultasiya hallarında xəstələrin müalicəsi, diaqnoz və xəstənin idarə edilməsi ilə yanaşı xəstəliyin qarşısının alınmasında effektiv iştirakı da tələb olunur. Hər bir laboratoriya həm də onunla işləyən peşəkar komandaya lazımi təlim və elmi imkanlar verilməlidir. Dünyada standart halına gələn yanaşmaların yaradılması və sənədləşdirilməsi, bu yanaşmaların bir-biri ilə ahəngdar şəkildə həyata keçirilməsi, fasiləsiz məlumat ötürülməsinin, izlənilməsinin təmin edilməsi və müqayisələrin aparılması üçün tibbi, sınaq və kalibrləmə laboratoriyalarının akkreditasiya işləri əhəmiyyət kəsb etmişdir.
Aparılan araşdırmalarla gəlinən nəticə tibbi laboratoriyaların önümüzdəki illərdə yaranan tələblər və rəqabət mühitində ISO 15189 standartının tətbiqinə daha çox cəlb olunmasıdır. Tibbi laboratoriyalarda bu standartın tətbiqi insan həyatı ilə birbaşa bağlı olan bu sahənin əhəmiyyəti ilə bağlıdır.

EN MASSE BEHAVIOUR OF GRANULAR MATERIALS IN SILO LOAD CALCULATIONS
Authors: L.O. Gumbe
Published: November 2022

Calculations of silo structure design problems, such as the evaluation of the interaction between theloads imposed on thin walled storage structures by grains and deformation of the storage structure wallor the evaluation of loads imposed on confining structures by particulate media during flow, would begreatly enhanced by accurate description of the load-deformation behaviour of stored particulate mediaen-masse. Early models represent situations which are extremely idealized versions of rea lifecounterparts. The solutions are those for various simple stress distributions of linearly elastic isotropichomogeneous media on the one hand, and certain results derived from the upper bound methods ofideally plastic analysis on the other hand. This paper discusses mechanical properties of granularmaterials and their impact on load distribution in silos.

Published: November 2022

Desorption isotherms of beef were determined by the standard static gravimetric technique, based on theuse of saturated salt solutions with water activities from 0.05 to 0.9. Equilibrium moisture content ofeach sample at different temperatures and water activities were determined. The stable moisture contentfor meat during drying was also established. The GAB, BET and Oswin models were used to fit theexperimental sorption data. Non-linear regression analysis was performed to estimate model parametersand fitting quality evaluated using the Coefficient of determination (R2) and the standard error ofestimate (SEE). The equilibrium moisture content decreased with increase in temperature at constantwater activity and increased with increase in water activity at constant temperature. The criticalmoisture was 10-20 % (d.b). The high values of R2 and low values of SEE for the GAB and Oswinmodels indicated that these models gave the best fit for the desorption data of beef
ESTIMATION OF SOIL EVAPORATION BY SOIL HYDRAULIC FACTOR FROM BARE DUNE SAND MULCH

Published: November 2022

A method is presented that employs soil moisture measurements and lysimetric reference evapotranspiration data to estimate a soil hydraulic factor for estimating soil evaporation. Soil evaporation is a complicated process. The soil evaporation process has two main stages. In this study, soil hydraulic factor was used to estimate soil evaporation under dune sand mulch. The soil hydraulic factor was derived from small pan evaporation data and soil evaporation data from dune sand soil columns. Dune sand soil columns were saturated and gravitational water was drained. The dune sand soil columns were then covered by dry Tottori dune sand soil of 0 cm, 2 cm and 5 cm thickness. Soil evaporation from these columns was measured gravimetrically. Potential evaporation was determined from small evaporation pans placed alongside the dune sand soil columns. Water was applied to three weighing lysimeters (for measuring actual soil evaporation) in a glasshouse to the field capacity of the dune sand soil. The weighing lysimeters were also covered by the dune sand soil of 0 cm, 2 cm and 5 cm thickness and that was dried naturally. Cumulative soil evaporation from dune sand soil columns and cumulative potential evaporation from small evaporation pans was used to determine the soil hydraulic factor under the three dune sand mulch treatments. The soil hydraulic factor was then used to estimate soil evaporation under natural drying conditions in the glasshouse. Estimated cumulative soil evaporation was compared with measured cumulative soil evaporation. The soil hydraulic factor overestimated cumulative soil evaporation during the falling rate stage of soil evaporation under 0 cm and 2 cm sand mulch. Adjusting the estimation by subtracting the difference between the estimated and the measured cumulative soil evaporation at the point where the square root of cumulative potential evaporation was equal to the soil hydraulic factor from the estimates moved the values closer to the actual measured. The soil hydraulic factor overestimated cumulative soil evaporation during the whole drying period under 5 cm dune sand soil mulch. The adjustment of the estimates did not move the values as close to the actual measured as in the 2 cm mulch. Using the soil hydraulic factor gave better estimates of cumulative soil evaporation during the constant rate stage under 0 cm and 2 cm sand mulch than under 5 cm sand mulch.

Published: November 2022

A compression molding machine was developed to produce bio-composite polymers using rice and coffeehusks as reinforcing filler (5% weight) with high density polyethylene (95% weight) as the base polymer.Rice and coffee husks are typically disposed by open burning in fields. Their use as reinforcing fillerstherefore reduces on the negative impacts of their disposal. The developed compression molding machinewas constructed using mainly mild steel and stainless steel. It consisted of heating chamber, mold base,compression shaft and observation window. A temperature controller was incorporated to regulate thetemperature in the heating chamber. Elongation, tensile strength and water absorption tests were carried outon the developed bio-composite polymers. Results indicated that inclusion of rice husks (5%) reduced thetensile strength and percentage elongation of the developed bio-composite polymer. Similar results wereobserved with coffee husk. Highest water absorption rates of 8% were observed for bio-composite polymersdeveloped with Arabica coffee husks.
