Authors: Mendonça José Carlos , Sales Renata Silva Barreto , Sales Dhiego da Silva 
Published: January 2023

De acordo com a ONU é crescente a tendência de urbanização sendo projetado um crescimento mundial em termos absolutos atingindo 665 em 2050. Utilizando imagens digitais orbitais e técnicas de sensoriamento remoto, este trabalho teve por objetivo avaliar o comportamento do balanço de energia da cidade de Campos dos Goytacazes, RJ contextualizando o estresse hídrico e correlacionando-o com a temperatura da superfície. Observou-se que o solo urbanizado em comparação com a área não construída apresentou os maiores fluxos de calor sensível e de calor no solo. Nas áreas urbanas foram encontrados os menores valores de saldo de radiação e fluxo de calor latente, gerando temperaturas mais elevadas no solo urbano e as áreas vegetadas apresentaram um maior fluxo de calor latente e menor fluxo de calor do solo. Observou-se ainda uma correlação de 96% entre o estresse hídrico e a temperatura, influenciando fortemente os fluxos da energia.Palavras-chaves: sensoriamento remoto, landsat 8, ilhas de calor, SEBAL Energy balance in the urban perimeter of Campos dos Goytacazes, RJ: A case study ABSTRACTAccording to the UN, the urbanization trend is growing, with a global growth projected in absolute terms reaching 665 in 2050. Using orbital digital images and remote sensing techniques, this work aimed to evaluate the behavior of the energy balance of the city of Campos dos Goytacazes, RJ contextualizing water stress and correlating it with surface temperature. It was observed that the urbanized land compared to the non-built-up area presented the highest fluxes of sensible heat and heat in the soil. In urban areas, the lowest values of radiation balance and latent heat flux were found, generating higher temperatures in the urban soil, and vegetated areas presented a greater latent heat flux and lower soil heat flux. There was also a correlation of 96% between water stress and temperature, strongly influencing energy flows, or for changes in the energy balance of the environment, further analyzes are proposed in different water conditions to compare with the results obtained with this work.Keywords: remote sensing, landsat 8, heat islands, SEBAL, temperature
Kirjallisuudentutkimus ja filologia
Authors: Parente-Čapková Viola 
Published: January 2023

Kirjallisuudentutkimuksella, ja varsinkin kirjallisuushistorialla on perinteisesti ollut iso rooli Suomessa ja kaikissa maissa, joissa kirjallisuus on osallistunut kansallisen identiteetin rakentamiseen. Onhan monesti osoitettu, miten moderni käsitys kirjallisuudesta kehittyi kansallisuusaatteen yhteydessä, ja miten vahvasti sekä kirjallisuus että kirjallisuushistoria ovat olleet mukana kansallisvaltioiden kulttuurien synnyssä. Kirjallisuuden ytimeksi on tuolloin nähty kieli.
Suomen kieltä on Suomessa pitkään opiskeltu kouluissa äidinkielenä ja Suomen kirjallisuutta yliopistoissa kotimaisena kirjallisuutena. Metaforisella tasolla kotimaisuus ja äidinkieli herättävät hyvin intiimejä mielikuvia. Muualta tuleva suomen kielen ja Suomen kirjallisuuden opiskelija tai tutkija voi kokea ne poissulkeviksi käsitteiksi – mitä jos ei puhu suomea äidinkielenään, mitä jos Suomi ei ole kotimaa? Voiko siitä huolimatta tuntea olonsa kotoisaksi suomen kielessä ja omistaa elämänsä Suomen kirjallisuuden lukemiselle, tulkitsemiselle ja tutkimiselle?

Published: January 2023

<p><strong>Abstract</strong><strong>: </strong>This research studied the recent implementation of sharia in the district of East Aceh by employing a qualitative approach with ethnographic methods. This research focused on sociological interpretations of the data gathered through the processes of observation of social interactions that reflected demographic patterns of daily intercourse, events, and traditions. The results showed that the implementation of sharia laws triggered pros and cons within society in East Aceh. Some people argued that the government did not put maximum effort into the implementation. Many other people, however, experienced positive changes in their life due to the implementation of sharia. There are still many challenges such as weakness of faith and social activities that are now forbidden there plus different understandings of sharia law still exist. Co-operation between the governments, scholars, and the people, in particular opinion leaders will be the key to continue successful implementation.</p><p><strong>Keywords</strong>: East Aceh, The Holy Qur’an and <em>al-</em><em>Hadîts</em>, People’s Perspectives, Islamic laws</p><p> </p><p><strong>Abstrak: </strong>Penelitian ini mengkaji implementasi pelaksanaan syariat Islam di Kabupaten Aceh Timur menggunakan pendekatan kualitatif dengan metode etnografi.

Published: January 2023

Naturies Indonesia is one of the UMKM for spice drinks in Macanan, Klaten, Central Java which is developing. As one of the growing UMKM, Naturies Indonesia is experiencing problems related to the distribution of its products. Naturies Indonesia has incurred transportation costs of Rp.442,100.00 per week in distributing its products to 5 distributors (Kudus, Jakarta, Shopee, Bandung, and offline). Due to human resource constraints, Naturies Indonesia does not yet have a thorough plan to reduce shipping costs in allocating products from production sites to customers or distributors. Through this applied research, this research aims to find the optimization of product delivery costs. Data were collected through interviews and documentation, then analyzed using the Northwest Corner and Vogel's Approximation methods. Analysis using the Northwest Corner method found a shipping cost of IDR 431,600.00, while the Vogel's Approximation method found a shipping cost of IDR 427,900.00. The shipping costs found were actually lower than the financing that had been issued so far.

High Rate Deposition in Cold Spray
Authors: Ozdemir Ozan C. , Muftu Sinan , Randaccio Lauren , Nardi Aaron T. , Champagne Victor K. , Widener Christian A. 
Published: January 2023

Abstract
Industrialization of cold spray brings along the questions of cost and time efficiency of various spray procedures. In this work, high rate deposition of tantalum was studied by producing coating specimens where the powder to helium mass flow rate varied from 5% to 14%. Quasi-1D fluid simulations predict a minimal effect of increased powder stream loading on particle impact velocity and temperature over those ranges, but the cost varies substantially. The experimental specimens, examined by using optical micrographs, porosity measurements, and hardness tests, show no discernable differences in the deposited samples. The increased stream loading rate, however, helped reduce the time required for processing the same amount of tantalum by a factor of three using identical helium spray conditions.

Published: January 2023

Abstract
This study investigates the in-flight behavior of particles during cold spraying by means of high-speed shadowgraph photography using a laser imaging system. It also characterizes the particle jet outside the nozzle for different powder sizes (&lt;10 µm to 155 µm) and densities (copper, aluminum). Observations of the jet reveal two low-pressure cold spray flow regimes, one stable, the other unstable, the effect and control of which are discussed.
Interfacial Strength of Plasma-Sprayed Hydroxyapatite Coatings
Authors: Ohki Motofumi 
Published: January 2023

Abstract
Tensile and shear adhesion strength tests were carried out to evaluate interfacial strength between hydroxyapatite (HA) coatings and titanium alloy substrates that that had been anodized or pre or post heat treated. Tensile and shear adhesion strength were both found to be influenced by pre and post heat treating, but not by anodization. The findings suggest that it is possible to estimate tensile adhesion strength from shear adhesion test results and that the interfacial strength of coatings must be measured directly, without using an adhesive.
Gearing Up Solution Precursor Plasma Spray for YAG TBCs for Production
Authors: Jordan Eric H. , Gell Maurice , Kumar Rishi , Jiang Chen 
Published: January 2023

Abstract
Yttrium aluminum garnet (YAG) has desirable properties for a thermal barrier coating (TBC), although there are two production challenges. One, YAG has a relatively low thermal expansion coefficient which leads to large thermal mismatch stresses, and two, amorphous phases are produced by atmospheric plasma spraying. Solution precursor plasma spraying (SPPS) has to potential to solve both problems. First off, it produces no amorphous phases. Secondly, it can produce a cracked microstructure that mitigates the CTE mismatch issue. To judge the adequacy of the properties of SPPS YAG, a summary of the properties of common TBCs is presented. It is shown that the properties of SPPS YAG fall within desirable or usable ranges. Current efforts described in this paper focus on improving the efficiency and rate of deposition.
Influence of Feedstock Pre-Treatment of Dynamic Flowability of HVOF Powders
Authors: Tillmann W. , Brinkhoff A. 
Published: January 2023

Abstract
This study investigates the effect of preheating on the dynamic flowability of HVOF powders, including conventional WC-Co, nano WC-Co, WC-FeCrAl, and Cr3C2-NiCr. The results show that the flowability of WC-Co powders can be significantly improved with a two-hour preheat at 200 °C. One explanation for the improvement is that moisture absorbed by the powder is released during pretreatment, but further study is required as it was found that dynamic density influences flow behavior as well.

Published: January 2023

Abstract
Due to the nonsymmetric distribution of the particle plume in conventional plasma spraying, significant influence of the gun scanning pattern can appear in the structure of the coatings obtained. In this study, three scanning patterns are used to deposit YSZ powder by means of air plasma spraying. Cross-sections of the coatings are examined and interfacial fracture toughness and hot corrosion tests are conducted. Improvements in coating adhesion and corrosion resistance were obtained by modifying the scanning pattern of the gun to decrease the possibility of horizontal weak bonding between spray passes.
The Microstructure and Properties of Plasma Sprayed Nanostructured 5 wt% and 8 wt% Yttria Stabilized Zirconia Coatings
Authors: Li Zheng , Gao Yang 
Published: January 2023

Abstract
Yttria stabilized zirconia with a composition of ZrO2-8wt%Y2O2 typically serves as the topcoat in thermal barrier coating systems. It has been reported, however, that YSZ with lower yttria content is more resistant to thermal shock and the effects of high-temperature sintering. To investigate these reports, nano-agglomerated 5YSZ and 8YSZ powders were deposited on FeCrAl substrates by atmospheric plasma spraying and the coatings were heat treated at 1400 °C for 1, 5, and 20 h. The nanostructure content in the 5YSZ samples was found to be about 20% higher, the microhardness 11% lower, and the size of unmelted particles about 27% smaller, which shows that bimodal structured 5YSZ has higher sintering resistance than traditionally used 8YSZ.
Numerical Design of an Adaptive-Pressure Plasma Coating Process
Authors: Ivchenko Dmitrii , Mariaux Gilles , Vardelle Armelle , Goutier Simon , Itina Tatiana E. 
Published: January 2023

Abstract
Thermal barrier coatings are generally produced one of two ways, depending on the thermomechanical loading expected. This study assesses an alternative approach in which the output of an air plasma torch is directed through two chambers connected by an expansion nozzle. In the first chamber, the particles evaporate under high pressure and temperature conditions. The vapor then passes through a supersonic nozzle into a low-pressure chamber where it condenses on the target substrate. A number of models are developed and used in order to assess the effects of process geometry and operating conditions on gas flows, powder vaporization efficiency, and nucleation and growth kinetics. Numerical simulations also informed various design decisions such as the length of the high-pressure chamber and the diameter of the expansion nozzle.

Published: January 2023

Abstract
Dense, nanostructured bismuth vanadate thin films were successfully deposited by aerosol deposition at room temperature. Aerosol deposition offers an alternative route for fabrication of photoactive metal oxide coatings as no binders or sintering processes are employed. A micron-sized bismuth vanadate powder was used to spray photoactive films (&lt; 1 µm) on conductive fluor-doped tin oxide layers on glass and titanium substrates. The thin films are photocatalytically active under solar light due to the band gap energies of bismuth vanadate, and their nanosized structure increases surface area and catalytic activity. The coatings obtained were assessed based on microstructure, layer thickness, mechanical integrity, and photoelectrochemical activity.

Abstract
This study assesses the mechanical performance of cold-sprayed aluminum 6061 coatings heat treated using focused IR radiation. The heat treatment was performed in-process with the aim of improving the ductility and strength of the coatings. The properties of the heat-treated samples are compared to those achieved using traditional annealing and as measured in as-sprayed samples. It was found that the rapid IR heat treatment increased the ultimate tensile strength of the coatings by 52% and elongation at failure by 43%.

Published: January 2023

Abstract
This study investigates the effect of heat treatment on the microstructure and tribological properties of TiB2-reinforced AlSi10Mg composite coatings produced by cold spraying. SEM and XRD analysis showed that the microstructure of the feedstock powder was well preserved in the as-sprayed material with uniformly distributed TiB2 nanoparticles, some aggregated clusters, and a cellular-like network of fine eutectic Si particles embedded in an aluminum matrix. With increasing heat treatment temperature, the Si particles grew larger in size, but significantly fewer in number and a reduction in microhardness was observed due mainly to the elimination of the work hardening effect and coarsening of the Si particles.
Quantification and Assessment of the Mechanical Strength of Low-Pressure Cold-Sprayed Tungsten Carbide-Nickel Metal Matrix Composite Coatings
Authors: Munday Guriqbal Singh , Hogan James David , McDonald André 
Published: January 2023

Abstract
WC-Ni metal-matrix composite coatings were deposited by low-pressure cold spraying using feedstock powders with different amounts of carbide. Uniaxial quasi-static tensile testing was conducted on the as-sprayed coatings to investigate the effect of porosity, particle size, and mean free path on mechanical properties. The evolving strain fields were measured via digital image correlation and image analysis was used to characterize coating microstructure. The coatings with higher carbide content exhibited better tensile properties, which is attributed to significant consolidation of the matrix, increased interfacial area, smaller average carbide size, and reduced mean free path between carbide particles.
Armor W-Cr Coatings for Plasma-Facing Components in Tokamaks by Cold Spray and RF-ICP

Published: January 2023

Abstract
Tungsten and its alloys are promising candidates for protecting plasma-facing components in fusion reactors such as tokamaks. However, processing is complicated by tungsten’s brittleness, CTE mismatch with copper and steel, susceptibility to grain growth and oxidation above 500 °C, and poor weldability. Given these factors, attention is shifting from conventional methods to powder and additive techniques. In this work, two technologies are employed for consolidation of W and WCr layers: cold kinetic spraying and inductively-coupled plasma spraying. Both methods overcome production challenges by depositing plasma-facing layers directly on structural parts, without the need for joining and the risk of oxidation. The properties of W and WCr coatings obtained by both methods are assessed by means of SEM, XRD, and mechanical and thermal analysis.
