Published: July 2022

En este trabajo analizo información acerca de las publicaciones en México de estudios del venado cola blanca (Odocoileus virginianus), venado bura (O. hemionus), venado temazate rojo (Mazama americana) y venado temazate café (M. pandora). La finalidad fue conocer qué sabemos y qué nos falta conocer acerca de las especies y subespecies de estos cérvidos. Compilé 502 trabajos escritos entre 1850 y 2001. De este total, el 24% fueron publicados durante los primeros 130 años y 76% en los últimos 20 años. El 1% correspondió a libros, el 13% a artículos arbitrados y específicos sobre venados, el 12% a secciones o capítulos de libros, el 16% a artículos de listados taxonómicos donde se incluyen a los venados, el 7% a artículos de divulgación, el 11% a tesis y el 40% a trabajos de Simposios publicados como memorias en extenso. Los venados temazates y bura son las especies menos estudiadas, mientras que el venado cola blanca es la especie más estudiada con el 75% del total de trabajos. En particular, solo cinco de las 14 subespecies de venado cola blanca en el país han sido las más estudiadas: O. v. texanus, O. v. couesi, O. v. sinaloae, O. v. mexicanus y O. v. yucatanensis. Basado en este análisis, considero que trabajos de investigación y manejo futuros deberán considerar: 1) Incrementar el número de investigaciones con los venados bura y temazates. 2) Realizar estudios genéticos y de distribución para definir cuantas subespecies de venado cola blanca existen en el país. 3) Realizar estudios considerando el nivel de paisaje para incorporar el efecto de la fragmentación del hábitat sobre las metapoblaciones de venados. 4) Realizar estudios a largo plazo. 5) Vincular los resultados de las investigaciones a problemas concretos de manejo. 6) Rescatar el conocimiento etnozoológico que poseen los grupos indígenas acerca de los venados. 7) Conocer el papel que tienen los venados como agentes estructuradores de la vegetación en hábitats tropicales. 8) Buscar formas de manejo de las subespecies de venado cola blanca que habitan en bosques tropicales. 9) Clasificar al país en regiones o provincias de manejo del venado cola blanca. 10) Generar bases de datos con la información de venados en México.

Наблюдение атомной флуоресценции кальция в лазерно индуцированной плазме с высоким пространственным разрешением
Authors: Бегларян Б.Г. , Закускин А.С. , Лабутин Т.А.
Published: July 2022

Определены экспериментальные параметры, оптимальные для изучения распределения атомов кальция в лазерно индуцированной плазме при пониженном давлении (16 Torr) методом атомной флуоресценции. Для возбуждения и наблюдения флуоресценции была впервые предложена и реализована схема нерезонансной флуоресценции с использованием переходов между состояниями 4s4p(3Po)-4p2(3P) с длинами волн 428.30 и 430.25 nm соответственно. На основании анализа влияния прогорания мишени на интенсивность сигнала флуоресценции и сравнения кривых насыщения флуоресценции показано, что для наблюдения флуоресценции предпочтительно использовать мишень из чистого карбоната кальция. Существенное (в 62 раза) усиление сигнала при наблюдении флуоресценции в оптимальных условиях позволяет пренебречь вкладом спонтанной эмиссии в интенсивность линий. Также показано малое влияние температуры в пределах, наблюдаемых в диагностируемой лазерной плазме, на заселенность используемого для возбуждения флуоресценции уровня. После оптимизации параметров это позволило провести измерения с пространственным разрешением и установить характер распределения атомов кальция в плазме вдоль ее латеральной координаты. Ключевые слова: лазерно индуцированная плазма, лазерная атомно-флуоресцентная спектрометрия, пространственно-разрешенные исследования плазмы.
Comparing Pre- to Post-COVID-19 Health Disparities Between Black and White Female Connecticut Medicaid Beneficiaries in Behavioral Health Utilization (Preprint)
Authors: Coman Emil , Agresta Thomas , Frazier Willie , Powell Wizdom
Published: July 2022

BACKGROUND

Broad health disparities (HDs) persist in Connecticut and the United States between minority and White patients, especially in access to and the utilization of behavioral telehealth services.

OBJECTIVE

We aimed to determine the geographic distribution of HDs in Connecticut between Black female and White female adults in Medicaid behavioral telehealth utilization in 2019 and 2020.

METHODS

We used the following spatial Connecticut data: (1) behavioral health utilization from Medicaid claims, from the Connecticut Department of Social Services, for the third quarters of 2019 and 2020; (2) mental health and drug and alcohol treatment facilities and ZCTA (ZIP Code Tabulation Area)-level descriptors from PolicyMap; and (3) Connecticut ZIP-to-ZCTA crosswalk data. Data were joined spatially, merged, and analyzed using spatial autoregressive models in Stata 17 (with outcome, predictors, and errors spatial lags). We computed ZCTA-level HDs comparing Black and White adult female Medicaid beneficiaries’ rates of face-to-face and telehealth behavioral services utilization. Spatial regressions were used to test spatial effects, which are extensions of classic regressions, that add neighbors’ effects to covariates.

RESULTS

Distances to nearest treatment facility vary quite widely in Connecticut by ZCTAs, from 0.06 mile to 13.4 miles—3.5 miles on average. The overall White female versus Black female HDs in behavioral health care utilization were impacted by the distance to the nearest facility, such that ZCTAs farther away from the nearest facility display larger Black versus White HDs—nearly statistically significant effect in 2019 and significant effect in 2020. In 2020, in ZCTAs situated farther away from treatment facilities, both White female and Black female Medicaid patients had higher telebehavioral health utilization (spatial effects +1.3% points and +2.0% points, respectively, for 1 more mile farther away). The differential Black versus White female HDs in telebehavioral health care utilization were not impacted by distance to nearest facility, according to the total effect (direct and indirect through neighboring ZCTAs; P=.26).

CONCLUSIONS

Quantitative analyses indicate broad differences in Medicaid enrollment and the utilization of behavioral health services among Black and White female Medicaid recipients in Connecticut and that these differences were rather stable between 2019 and 2020. It appears that the expansion of telebehavioral health services in 2020 enhanced the access to treatment among residents who were located furthest away from providing facilities.

Patients' health data are routinely collected and stored in hospitals for care delivery. If the data is made available for researchers, it can be secondarily used for artificial intelligence research and development. Data sharing and reuse brought new ethical concerns to healthcare organizations and the medical and research communities alike. In this article, we discuss the main ethical aspects that underpin data sharing decisions: health data ownership, patient consentment, privacy, personal data anonymization, and the purpose of data reuse. Three pillars should guide organizations in data sharing decisions: regulations, ethics, and support for increasing patient engagement. Efforts should be undertaken to explain the risks, benefits, and opportunities of data sharing to patients and society at large. There is a concern that algorithms' outputs are biased, which may be a result of biased datasets. To prevent this, datasets must include a representative cross-section of the population so that discoveries and innovations are generalizable to all people. A deeper understanding of health data reuse by different stakeholders are decisive for elevating population health informatics research.
PANDEMIJA COVID-19 I GLOBALNI KAPITALIZAM
Authors: Suvakovic Uros
Published: July 2022

U radu se ukazuje na društvene efekte koje je proizvela pandemija COVID-19. Oni su takvog značaja da su u velikoj meri izmenili svakodnevni život ljudi na Planeti, dovele do produbljivanja socijalnog raslojavanja, bitno uticale na geopolitičke odnose u savremenom svetu, čak dovele u pitanje i nauku kao oblik ljudskog saznavanja sveta i njen autoritet, što se od nastanka racionalizma nije moglo ni zamisliti.
Polazi se od pretpostavke da je pandemija COVID-19 direktna posledice hiper ubrzanog procesa globalizacije, što je i omogućilo da u kratkom roku izazove velike društvene promene u čitavom svetu. Globalni kapitalizam, zasnovan na neoliberalizmu (globalizmu) kao svom idejnom temelju, je idealno okruženje ne samo za širenje pandemije izazvane novootkrivenim SARS-CoV2 virusom, već i za izazivanje čitavog niza društvenih posledica. Ipak sve te posledice i brojnost promena do kojih je došlo, nije (za sada) prouzrokovalo promenu sistema. Globalni kapitalizam i dalje ispunjava svoju osnovnu funkciju: uvećanje profita najbogatijih. Sve ovo zahteva značajno angažovanje društvenih nauka u istraživanja pandemije COVID-19, posebno sa sociološkog aspekta, te stoga i zasnivanje posebne sociološke discipline – Sociologije COVID-19.

Authors: Maksimovic Marijana
Published: July 2022

Kriza izazvana pandemijom KOVID 19 buknula je u martu 2020. godine, donela je vreme neizvesnosti kako za pojedince, tako i za privredu i preduzeća . U prvim mesecima krize, nastala je i najveća materijalna šteta za preduzeća, ali i gubitak radnih mesta za određen broj zaposlenih lica.
Predmet ovoga rada je ponašanja razvijenih zemalja i analiza tržišta rada tokom pandemije. Cilj istraživanja je da se pokaže šteta izazvana pandemijom KOVID 19 i kakve su posledice koje su dovele do velikih promena. U radu je korišćen teorijsko-metodološki pristup koji se ogleda u opisno-analitičkoj metodi. Dobijeni rezultati ukazuju na velike negativne efekte po ekonomije zemalja koje su najviše pogođene ovom pandemijom. Došlo je i do promene u međunarodnim odnosima na primer, odnosu SAD i Kine. Zaključak je da je tokom pandemije došlo do poremećaja komunikacije i istaknuta je socijalna distanca. Iz tih razloga je korišćen digitalni marketing kako bi nadomestio komunikaciju proizvođača sa zaposlenima i potrošačima.
Prethodna svetska ekonomska kriza iz 2008. godine, ali i ova iz 2020. godine, doprinele su da se neformalni rad kao oblik rada još više razvije. U potpuno nepovoljnom položaju našli su se ženska radna populacija i mladi koji traže zaposlenje, slabije obrazovani, kao i teško zapošljive kategorije kao što su na primer invalidi rada.

Published: July 2022

Abstract: The use of high volume baryte concrete fits in very well with sustainable development. High performance concrete is being widely used all over the world. High volume baryte concrete mixtures contain lower quantities of cement and higher volume of baryte (up to 40%). The use of baryte concrete at proportions ranging from 0 to 40% of total cementations binder has been studied extensively over the last twenty years and the properties of blended concrete are well documented. The replacement of baryte as a cement component in concrete depends upon the design strength, water demand and relative cost of ash compared to cement. The specific gravity and chemical properties of baryte cement, coarse and fine aggregate were determined. Cubes and the cylinder cubes werecured for 7 and 28 days respectively. The cubes and cylinder cubes were subjected to compressive strength tests after densitydetermination at 7 and 28 days respectively. The slump of different baryte percentage are compared
Efficient Crime Analysis Based on Hybrid Approach by Combining Dynamic Time Wrapping Algorithm with K-Means Clustering Approach.
Authors: Gendre Vinod
Published: July 2022

Abstract: Crime is a preeminent issue where the main concern has been worried by individual, the local area and government. Wrongdoing forecast utilizes past information and in the wake of investigating information, anticipate the future wrongdoing with area and time. In present days sequential criminal cases quickly happen so it is a provoking assignment to anticipate future wrongdoing precisely with better execution. Clustering different time series into similar groups is a challenging clustering task because each data point is an ordered sequence. The most common approach to time series clustering is to flatten the time series into a table, with a column for each time index (or aggregation of the series) and directly apply standard clustering algorithms like k-means. But this doesn’t always work well on Time Series Data. The paper focuses on combining the features of K-Means Clustering algorithm with Dynamic Time Wrapping Algorithm for efficient Crime prediction and analysis

Wrinkling Defect in Sheet Metal Process using Finite Element Analysis
Authors: Nizam Maruf
Published: July 2022

Abstract: Deep drawing is popular sheet metal forming process. Deep drawing process is the most common metal forming process frequently used in automobile industry, the packaging industry and the house hold appliances industry to manufacture products with more complicated shapes and curvatures. Any metal that can be processed into sheet form by a rolling process should be sufficiently ductile to be capable of deep drawing. Both hot and cold rolled sheet products are used in deep drawing processes. The basic theories governing the deep drawing are based on application of theory of plasticity to the deep drawing process. It is very difficult to apply these theories and arrive at a general solution which can handle any arbitrary geometry. The idea of finite element analysis is to find the solution of complicated problem in relatively easy way. The finite element analysis has been a powerful tool for the numerical solution of a wide range of engineering problem. There are some possible failures likely occur during the process, like wrinkling, necking, scratching and surface defects. As thinner materials tend to be used in automotive industry, wrinkling has become the most important problem among the other defects. The study also aims to investigate wrinkling and its prevention. For this purpose, the commercial finite element analysis code Explicit Dynamic FEM model will be used

Published: July 2022

Improving the technical and economic indicators of machine building is possible by increasing their production, reducing their dimensions and masses, reducing energy consumption and reducing their reliability, which ultimately will correspond to the norm for reducing construction time (putting objects into regulatory significant ones), the labor intensity of construction and installation works and increase in capital costs for temporary buildings and structures. A separate and specific type of machines for construction are drilling machines based on industrial tractors of the T10 type. As a rule, this uses a hydraulic volumetric drive of the main working bodies. The traditional design consequence of the drilling string drive of the machine is the use of a low-torque hydraulic motor with a gearbox. At the same time, high-torque hydraulic motors have grown in domestic industrial resistance, making it possible to provide the necessary torque on the drilling rig without using a gearbox. This solution allows you to simplify the light, reduce production costs and increase the reliability of the drive in operation. This article provides a comparative analysis of some of the advantages and disadvantages of the geared and gearless variants of the drilling string drive, in relation to the mass-produced machine BTS-150.

The issues of optimizing the parameters of a hydraulic hammer on the basis of differentiating a complex impulse system into subsystems by drawing up differential equations for all bodies participating in motion and using the theorem on changing the kinetic energy and momentum are considered. It has been established that the force of fluid pressure is the main source of friction in the sealing unit, the value of which depends on the pressure of the working medium, the coefficient of friction of the cuff material and the size of the contact surface of the seal. The research results can be used in the development of a method for calculating the optimal parameters when designing a hydraulic hammer, and the obtained expressions can be used to establish the influence of some parameters on the efficiency of the energy conversion process as a whole, as well as for other schemes and tasks.

In modern geopolitical conditions, the transportation of energy resources and, in particular, liquefied natural gas to the Kaliningrad region has acquired key importance. The existing infrastructure facilities and technical devices, in particular the underground gas storage «Kaliningrad» and the floating Storage Regasification Unit «Marshal Vasilevskiy», make it possible to overcome the current crisis in many ways. At the same time, it should underline that the implemented method of liquified natural gas transportation to the Kaliningrad region and its regasification has different drawbacks, as a result of natural losses and imperfections of technological solutions, part of the liquefied gas may be lost. The article presents the results of a study of the causes and preliminary projected volumes of losses of liquefied natural gas during its transportation by the floating Storage Regasification Unit «Marshal Vasilevskiy» from the port of Ust-Luga to the Romanovo underground gas storage with subsequent regasification and injection into underground reservoirs. The analysis of possible technical and technological solutions allowing to reduce the volume of losses and save the transported liquefied natural gas for subsequent use is carried out.

Spirituality is one of the essential aspects of one’s life. It offers a broader perspective towards a meaningful life while undergoing trials such as caring for children with cancers. Cancer caregivers commonly experience physical, emotional, social, and spiritual challenges. Spiritual issues such as lost hope and associating negative meanings with cancer prognosis may reduce the caregiver’s quality of life. However, this caregiving burden can be a great source of post-traumatic growth. Therefore, the objective of this study is to explore spiritual change, a significant domain in post-traumatic growth among 24 caregivers of children with cancer at one of the teaching hospitals in Kuala Lumpur. Following in-depth interviews, the result of the thematic analysis demonstrated two themes; main religious and mindfulness practices, a significant caregiver’s spiritual development. The majority of caregivers reported increasing spiritual awareness levels, feeling closer to God, and focused on religious practices as caregivers coping mechanisms and patients’ complementary therapy. Hence, spiritual concerns among families of children with cancer need to be addressed during cancer treatment. This study suggests the development of an appropriate quick reference on spiritual aspects for caregivers which would be useful during the cancer trajectory and improve the whole family’s quality of life.

This includes al-Khawarizmi lunar crescent visibility criterion in 8th century until al-Lathiqi lunar crescent visibility criterion in 17th century. Numbers of review on mathematics and astronomy during the Middle Age, however the number of review that specifically written for Middle Age lunar crescent visibility criterion limited, with majority of review is written to study the historical of Middle Age science, astronomy, mathematics and geography as a whole, and not converge on lunar crescent visibility criterion. . Therefore, this article aimed to provide a review on Middle Age lunar crescent visibility criterion. The review is conducted using literature analysis, snowball literature search and specific inclusion and exclusion criteria. The review is performed based on 13 works on lunar crescent visibility criterion that pass the selection criteria. The review found out that most of the lunar crescent visibility criterion is based on al-Khawarizmi arc of separation and solar longitude, lunar crescent visibility criterion, with exception on Ibn Tariq, Ibn Qurra and Ibnu Yunus lunar crescent visibility criterion that adopt angular distance or elongation. The review suggest that a new outlook on Middle Age lunar crescent visibility criterion study can be done, by conducting an assessment on new data of moonsighting, and comparing with modern lunar crescent visibility criterion research.

The present study was conducted in a sewage treatment plant, called "El Kouwaer", located in the department of Mascara, North-West of Algeria. Mainly, the objective of this investigation is to evaluate the relevant settling and pollution parameters and to assess the proliferation level of filamentous microbial communities during the dysfunction period to further the effectiveness of the operative treatment. Sludge parameter values were estimated such us Settling Test, Diluted Sludge Volume Index (DSVI), and Total Suspended Solids (TSS) content to set up the sludge classification, the performance analysis of treatment was conducted by computing pollution indicators and removal efficiencies of organic pollution, as well as the Principal Component Analysis (PCA) of dysfunction parameters. The results showed that in aeration tanks 65% of samples represented a maximum Filament Index (FI) of 6. Diluted Sludge Volume Index (DSVI) was greater than 300 mg/L in 23% of samples. A high level of filamentous bacteria biodiversity was also noted during the assessment of the (FI) including Microthrix parvicella, Bogiotae, and Sphaerotilus natans. The effluent in the biological unit was characterized by BOD5/COD ratio of 0.17 and COD removal efficiency of 53.32%. Those results demonstrated that the sewage treatment plant is frequently affected by bulking problems. This study had confirmed the importance of continuous monitoring of different process parameters like Wastewater Biodegradability Index, Dissolved Oxygen, filamentous flora, and Dilute Sludge Volume Index (DSVI) to avoid irreversible damage at the level of a wastewater treatment plant.

In this study the aim was to evaluate alternative crops able to tolerate thefuture rise in salinity, likely to occur in the East Mediterranean coastal areas. For this, two genotypes of pearl millet (Tall and IP13) were submitted to saline conditions (4, 8, 12 dS.m-1 and 2 dS.m-1 as control) in a field trial. Water consumption using neutron probe technique, physiological response and the production were studied. The neutron probe technique showed that 96% of consumed water originated in the upper 0.45 m. As salinity increased, water consumption became shallower, suggesting a different root distribution. Physiological aspects related to plant height, foliar potassium and uptake of nitrogen were investigated. Tallest plants were found in 4 dS.m-1 in Tall, and in 2 dS.m-1 in IP13. Foliar potassium was similar in Tall variety, while IP13 excluded the potassium, in order to reduce cellular ions. In Tall the 15N technique showed that 40-50% of plant N originated from the fertilizers, irrespective of saline conditions. Fresh weight was not different between 4 and 8 dS.m-1, in three cuts out of five in 2016 and 2017. Tall produced higher dry matter, especially under saline conditions. Best water use efficiency was in 4 dS.m-1 (10.4 kg.m-3 in Tall; 8.8 kg.m-3 in IP13). The plotting of dry matter production against salinity gave quadratic equations, with a peak at 5.6 dS.m-1 for IP13 and 7.1 dS.m-1 for Tall. Tall can be used for phytoremediation of soils in coastal areas, and as a forage crop.

This paper presents a 3D non-linear numerical model, developed to predict the mechanical behaviour of simply supported steel-concrete composite beams under three-point bending stress. Using on Abaqus software a 3D model is created, which takes into account all the elements of the steel-concrete composite beam. The concrete slab, steel beam, and studs are modeled using solid elements, reinforcing bars are neglected. The geometrical and mechanical characteristics are based on beams tested in previous studies. The non-linear behaviour of steel-concrete materials is considered and the interaction between the different surfaces is taken into account. The deflection and slip results at the interface of slab and steel sections showed good agreement with experimental and analytical results. The maximum load value is close to that obtained by a plastic analysis of the composite section according to the Eurocode (1994) rules, with a relative deviation of 10%. Furthermore, the behaviour of increasing the reinforcing plate thickness on the composite beam gives an increase in maximum load and a decrease in the slip at the steel-concrete interface.

The Lebanese economy primarily relies on the service sector, and tourism is one of the most important economic service sectors in Lebanon, for it constitutes 20% of Lebanon’s national income. One particularly interesting aspect of tourism is rural tourism, which could represent a significant economic opportunity for Lebanon, especially after the outbreak of COVID-19 pandemic and amongst the Lebanese economic crisis. This article focuses on nine main factors that are believed to have an influence on the decision-making process of tourists visiting rural destination in Lebanon. These factors include tourist attraction, tourist transportation, accommodation, tourist entertainment, natural environment, hospitality environment, tourist information, marketing and safety and security. The aim of this study is to analyze the perception of Lebanese tourism stakeholders towards the mentioned nine factors that could affect the decisions of tourists, thereby aiding those stakeholders to create appropriate tourism strategies that match the needs of tourists more accurately. The main research question addressed is stated as follows: “What are the factors that have the most impact on the decision-making process of tourists visiting rural tourism destinations in Lebanon?” Tourism stakeholders targeted in this article include tourists visiting Lebanon, tour operators, the Lebanese government and local authorities such as municipalities, local residents of tourism destinations, the private sector, NGOs and others. As for the research methodology, a quantitative research approach based on a self-designed survey was applied. Primary data was collected from several rural Lebanese villages randomly selecting 354 respondents of varied profiles. These respondents were also interviewed face-to-face. Data obtained were analyzed using the SPSS 20.0; The Chi Square test (two-way contingency table) and a correlation analysis were used to analyze data and check the validity of the proposed hypotheses. Results of the study revealed that (i) transportation facilities, (ii) the natural environment, and (iii) the safety and security of a tourism destination were the most impactful factors that affected decisions of tourists. It is recommended that tourism stakeholders carefully study their target market in order to meet the corresponding tourism demands. Nevertheless, stakeholders such as the government should cooperate with other stakeholders and enroll them in tourism planning in order to optimize tourism capacity and achieve sustainable tourism development in the future. A future perspective of the subject could highlight foreign currency exchange rate and COVID-19 vaccination as additional factors that could have a remarkable impact on the decision-making process of tourists considering Lebanese rural tourism destinations.

Crimean-Congo haemorrhagic fever (CCHF) is an emerging tick-borne human
disease in Spain. Understanding the spatiotemporal dynamics and exposure
risk determinants of CCHF virus (CCHFV) in animal models is essential to
predict the time and areas of highest transmission risk. With this goal,
we designed a longitudinal survey in two wild ungulate species, the red
deer ( Cervus elaphus) and the Eurasian wild boar ( Sus
scrofa), in Doñana National Park, a protected Mediterranean
biodiversity hotspot with high ungulate and CCHFV vector abundance, and
which is also one of the main stopover sites for migratory birds between
Africa and western Europe. Both ungulates are hosts to the main CCHFV
vector in Spain, Hyalomma lusitanicum. We sampled wild ungulates
annually from 2005 to 2020 and analysed the frequency of exposure to
CCHFV by a double-antigen ELISA. The annual exposure risk was modelled
as a function of environmental traits in an approach to understand
exposure risk determinants that allow us to predict the most likely
places and years for CCHFV transmission. The main findings show that
H. lusitanicum abundance is a major driver of the fine-scale
spatial CCHFV transmission risk, while inter-annual variations in the
risk are conditioned by virus/vector hosts, by host community structure
and by weather variations. The most relevant conclusion of the study is
that the emergence of CCHF in Spain might have been associated with
recent wild ungulate population changes promoting higher vector
abundance. Decreasing wild ungulate population densities could reduce
vector abundance and thus virus prevalence and the risk of CCHFV
transmission to humans.

Functionally graded materials are important in laboratory and industry. These materials have opened a new area of research. These functionally graded materials can be produced as a result of composite material by the adding more materials to get desired properties to make it perfect for suitable applications. In this paper, the focus is on the modelling of functionally graded material that is developed to resist wear by any friction or erosion by any liquid. Cemented Carbide (WC) was selected as a composite material that is commonly used in industrial or lab. Before developing the model of functionally graded material (FGM), a detailed study has been carried out on the composite material using the finite element method to find a numerical solution and compared it to the exact one. The analytical solution was obtained by using MATLAB and numerical solution by ANSYS. Besides these software’s SolidWorks and SkyCIV programs were utilized for analysis and plotting purposes. At the end of the project, one layer titanium carbonitride (TiCN) was added to one face and the same layer was added to the four faces to make the comparison between the two cases to select the best model using the results of a total of deformation.
