CaZrO3 is a material for thermally sprayed ceramic coatings to which so far only a little attention was paid. This material has a high melting point, good thermal stability and a coefficient of thermal expansion close to that of steel. In this paper water stabilized plasma spraying (WSPR) and atmospheric plasma spraying (APS) were used to prepare CaZrO3 coatings. The spraying feedstock was prepared from fine CaZrO3 powder by agglomeration (spray drying) and sintering. Powders with three different particle sizes (- 45 + 20 µm, - 63 + 45 µm and -90+63 µm) were used in the experiments. The coarse fractions were used for WSP spraying, while the fine one was sprayed with the APS process. Plasma sprayed materials were studied from the point of view of phase changes and influence of the powder size on structure of coatings. The changes of phase composition were studied by X-ray diffraction on coatings as well as on free flight particles. Formation of a cubic phase with a reduced content of CaO in comparison to CaZrO3 was observed. Its formation is probably connected with evaporation of CaO during spraying. This cubic phase is similar to the phase obtained by spraying of ZrO2+5%CaO. Plasma sprayed coatings were characterized by light and scanning electron microscopy (SEM) and by density and porosity. Coefficients of thermal expansion of plasma sprayed layers from CaZrO3 were measured.

Published: September 2022

The life and thermal properties of plasma sprayed TBC – widely used in gas turbine engines – are closely related to the microstructure of the ceramic top coating. Especially, the thermal conductivity of this ceramic coating is induced by the void shapes and networks which are in turn determined by both the spraying conditions and the feedstock material. This study has been performed to optimize the ceramic coating microstructure. First, a hollow zirconia powder was elaborated in the laboratory and compared with a commercial hollow powder. Then, the Taguchi method was performed on thermal spray operating factors to optimize their beneficial effects on the Thermal Barrier Coating (TBC). A new hollow powder with small grains was elaborated using spray drying process. That spray dried powder based on yttria partially stabilized zirconia was optimized using drying simulation tests. It was shown that the formulation and the state of dispersion of the slurry allow to control the powder morphology (from dense to hollow shape). Moreover, for hollow powder, it is possible to vary the thickness of the shell. According to these results, a hollow powder (size ranging from 36 to 130 µm and an 11 µm shell thickness) was elaborated as an original feedstock to produce plasma sprayed TBC. The agglomerated powder was consolidated in an oven and then was compared to a commercial hollow yttria zirconia powder during thermal spray tests. Coating experiments were based on a limited number of operating factors, which have an influence on the deposit microstructure. The seven selected spraying factors concerned the plasma (primary and secondary gas flow rates, arc current), the cooling and the powder deposition (spraying distance, spraying angle, traverse speed). Experiments based on these factors were carried out to elaborate a Taguchi fractional-factorial L16 design. The resulting as sprayed coatings characteristics were quantified with respect to deposition efficiency, roughness (Ra) and porosity (image analysis technique). Through statistical calculation, the parameters that have relevant influence on the coating properties were identified, and their relative importance and some of their interactions were studied. The final aim is to produce an effective thermal barrier coating with a reduced thermal conductivity.
A New Environmental Barrier Coating System on Carbon-Fiber Reinforced Silicon Carbide Composites
Authors: Latzel S. , Vaßen R. , Stöver D.
Published: September 2022

Carbon-fiber-reinforced silicon carbide composites (C/SiC) are promising materials for high temperature light weight structural components. However, a protective coating is necessary to prevent the oxidation of the carbon, especially at temperatures above 400 °C. Also the silica scale, which often forms on top of the C/SiC, must be protected from water vapor contact as the silica scale is not stable under these conditions. Hence, a protective coating, an Environmental Barrier Coating (EBC), is needed to shelter the material from the environmental influences of oxygen and water vapor. Current EBC systems employ multiple layers, each serving unique requirements. However, any mismatch in the coefficients of thermal expansion (CTE) leads to internal stress and results in crack formation. In this case, oxygen and water vapor penetrate through the EBC, reducing the lifetime of the component. Mullite (Al6Si2O13) is used in many known EBC systems on silicon-based ceramics either as an EBC itself or as a bondcoat. Due to its low CTE and its sufficient thermal cycling behaviour, mullite was chosen in this investigation as a first layer. As mullite suffers loss of SiO2 when exposed to water vapor at high temperatures, an additional protective top coat is needed to complete the EBC system. Different oxides were evaluated to serve as top coat, especially high temperature oxides with low coefficients of thermal expansion (LCTE). An Environmental Barrier Coating containing mullite as bondcoat and a LCTE oxide as a top coat is proposed. Both layers were applied via atmospheric plasma spraying. Results on the influence of processing conditions on the microstructure of single mullite and LCTE oxide layers and also mullite / LCTE oxide systems will be presented. Special emphasis was directed towards the crystallinity of the mullite layer, and in the top layer towards low porosity and reduced crack density.
Ceramic / Fluoropolymer Composite Coatings by Thermal Spraying : Effects of Parameters
Authors: Mateus C. , Costil S. , Coddet C.
Published: September 2022

In recent years, polymers have grown successfully in industrial applications such as protection against corrosion, chemical or wear resistance. However, the use of these materials is often limited because of their poor abrasion resistance. For example, PTFE is certainly a polymer that has the most attractive properties such as low coefficient of friction but it is characterized by a very low scratch resistance. These restrictions can be overcome by use of composite structure. This way, mechanical resistance can be then provided by ceramic materials. As a result, this study is devoted to feasibility of ceramic – fluoropolymer composite coatings by plasma spraying. Two types of organic powder (PTFE and PFA) and that of alumina powder were chosen. Blends of these compounds were then sprayed. Owing to thermal properties of both materials, specific spray parameters must be optimized. Two varied parameters were picked up (spraying distance and plasma gas mixture) and their effects on the coating quality were estimated by several types of characterization (morphology, polymer rate, roughness…).

A middle aged male with history of Fallot type Double outlet right ventricle and coarctation of aorta who underwent multiple surgeries since childhood. With RV to pulmonary artery conduit and end to end coarctation repair initially, followed by aortic valve, pulmonary valve and RV-PA conduit replacements later. He subsequently developed significant flow through a fistula between a previously coiled aortic pseudoaneurysm and LVOT. This was percutaneously closed with a vascular plug and additionally a PFO, detected, was closed with a device.
Patient returned to the clinic with decompensated heart failure. Updated imaging demonstrated that the plug had migrated and together with the coil, which was impinging on the AVR, resulting in severe supra-valvar AS and continuous significant persistent residual flow across the Aorta- LVOT fistula via false aneurysm.
Our case highlights the importance of using multimodality imaging for complex congenital heart diseases. In view of high surgical risks associated with previous multiple sternotomies and patient’s preference, percutaneous approaches were adopted initially: however, it was unfortunate to see the migration of vascular plug. After successful deployment of AVP, migration or recanalization is rare, but should not be completely discounted.

The air infiltration through building envelope mainly depends on the doors and windows tightness considered by means of the corresponding effective leakage areas and the pressure difference between the building exterior and interior. Although the standards provide simple methods to estimate the parameters that control the air movement, significant differences in the volumetric flow of fresh air are observed between the standardized and the most accurate traditional methods. Our aim is to evaluate the infiltration in a two-storey building with a large central atrium during the typical day in January by considering all the relevant parameters. The analytical result is incorporated to the numerical simulation with EnergyPlus to determine the internal temperature evolution that is sensitive to the air intake. Simulation results are compared with in-situ measurements. It is found that the air infiltration rate calculated from the standardized procedure only enables the internal temperature evolution to be reproduced with a substantial adjustment of the design air infiltration rate. The methodology developed is useful to calculate the infiltration in buildings under actual use conditions and assess the air leakage when measurements are not available.

The relevance of this study is conditioned upon the need to establish the possibility of using artificial lighting to increase the productivity of cows with tethered maintenance. This paper is aimed at identifying the effect of adjustable lighting of the feed table with LED lamps on the dairy productivity of cows. The cowshed lighting was provided by the SmartAC (LRC) automatic control system. The research method was to analyse the dynamics of cow milk yield under controlled photoperiod conditions and the level of illumination of the room. Two groups of cows were formed: experimental cows were kept in an experimental cowshed with natural illumination of the feed table of 101±20.2 lx and artificial illumination of 202±19.9 lx, the control group was kept in a typical 2-row room for 100 heads, in which natural illumination feed table was 139±22.8 lx, artificial – 26±3.2 lx. The duration of the photoperiod was 16 hours, and the ratio between natural and artificial lighting depended on the astronomical length of the day. Milk productivity of cows was assessed according to the method of control milking. Milk yields were recorded one month before the installation of the experimental lighting system (in February) and for the next four months (from March to June). Before the installation of the experimental lighting system, the difference in milk yield of cows was not statistically significant. In the future, despite fluctuations in the amount of milk yield caused by feeding, the experimental group of cows exceeded the control group in terms of milk productivity. The advantage of the cows of the experimental group in terms of daily milk yield was from 2.3 kg in March to 5.8 kg (p<0.01) in May. During the period of maximum daylight hours (June), the effect of artificial lighting on the dairy productivity of cows was insignificant. It was noted that the increase in the preference of experimental cows for milk yield occurs over several months, and the positive impact of improved lighting of the feed table increases along with an increase in milk productivity on the farm. That is, the higher the feeding level, the greater the effect of lighting control. The obtained results were confirmed after the analysis of the productivity of analogue cows by age and lactation phase, selected from the experimental and control groups. The results of the study are of practical value for the improvement of lighting in cowsheds with tethered housing

Published: September 2022

Вступ. Вирощування зерна, зокрема пше­ниці, має давні традиції, є широко розви­не­ним і важливим для забезпечення добробуту населення, задоволення продовольчих потреб, створення робочих місць, одержання фінансового прибутку, у т. ч. внаслідок експорт­них операцій. Особливу загрозу для забезпе­чення продовольчої безпеки на глобальному рівні становить війна, розпочата РФ на тери­торії України, яка традиційно є постачаль­ником пшениці для багатьох держав. Проблема. З огляду на значний запла­но­ваний обсяг експорту продовольчої пше­ниці, високий попит на неї на внутрішньому ринку, цінову різницю у порівнянні з фураж­ною, не­рівномірність якості через погодні умови віро­гідним є підвищення цін на про­дукти її пере­робки на національному рівні, зниження їхньої споживної якості. Війсь­кова агресія РФ, бойові дії, що ведуться на знач­ній території України, ставлять під загрозу посівну кампанію 2022 р. і, як результат, про­довольчу безпеку. Мета статті – комплексний аналіз стану світового ринку зерна пшениці та визна­чення основних тенденцій і перспектив його подальшого розвитку, зокрема в умовах воєн­них дій в Україні. Методи. Застосовано загальнонаукові мето­ди аналізу та синтезу, порівняння, виокрем­лення, узагальнення й результуючої систе­матизації дослідженого матеріалу. Результати дослідження. Досліджено ди­на­міку та структуру виробництва зернових культур, на основі чого встановлено, що пше­ниця є однією з найбільш поширених серед них. Визначено основні держави-експортери та імпортери на світовому ринку, проана­лізо­вано головні тенденції розвитку. У 2022/2023 МР внаслідок бойових дій в Україні забез­печення потреб багатьох країн, що імпор­тують пше­ницю, опинилося під суттєвою загро­зою та потребує пошуку додаткових поста­чальників цієї культури. Проведено аналіз її урожайності в Україні впродовж 5 останніх років, визначено області – лідери з вироб­ництва у поточному маркетинговому році.Черезвійну в Україні прогнозується зни­ження врожаю пшениці. Висновки. Основними тенденціями роз­витку світового ринку пшениці є зміна біль­шості міжнародних транспортних сполучень її постачання, підвищення попиту на цю куль­туру в порівнянні з готовим борошном, вве­дення багатьма державами торговельних квот на неї. Вітчизняний урожай пшениці у 2021/ 2022 МР став рекордним (32.8 млн т). Незважаючи на своєчасний початок посів­ної кампанії зернових у 2022 р., через бойові дії у багатьох регіонах України прогно­зується зниження обсягу майбутнього врожаю. Для забезпечення внутрішніх національних потреб обґрунтованим є подальше встанов­лення експортних обмежень на пшеницю.

Influence des facteurs individuels et dyadiques sur l’ajustement sexuel des couples lors d’un cancer du côlon
Authors: Stulz A. , Favez N. , Flahault C.
Published: September 2022

Contexte : Le cancer du côlon est le troisième cancer le plus diagnostiqué au monde et a un impact sur tous les aspects de la vie des patients et de leur partenaire. Jusqu’à présent, peu d’études ont étudié l’ajustement sexuel des patients et aucune n’a analysé les interactions entre les partenaires.

Objectif : Décrire les facteurs individuels et dyadiques liés à l’ajustement sexuel des couples.

Méthode : Treize couples ont répondu à un ensemble de questionnaires portant sur le soutien social, la communication et les stratégies de coping dyadique et la satisfaction sexuelle. Des analyses non paramétriques ont été réalisées sur les données quantitatives.

Résultats : Le soutien social, la communication et les stratégies d’adaptation dyadique jouent un rôle dans l’ajustement sexuel des couples. La satisfaction ressentie par les patients et leurs partenaires quant au soutien conjugal est corrélée positivement à l’ajustement sexuel du patient. La qualité de la communication des patients quant au stress engendré par la maladie est liée à la satisfaction sexuelle des partenaires. Le coping dyadique de soutien comme la gestion commune du stress favorisent l’ajustement sexuel des patients et des partenaires. Ces stratégies démontrent l’importance de l’unité au sein du couple, le cancer étant abordé comme une « maladie du couple ». Cet engagement mutuel semble favoriser la satisfaction sexuelle des couples.

Conclusion : Gérer la maladie et le stress lié aux traitements en tant que couple et percevoir son partenaire comme une source de soutien satisfaisante est particulièrement bénéfique pour la satisfaction sexuelle des couples dont un membre est atteint d’un cancer du côlon.

Published: September 2022

This study explores whether Pakistan's current account deficit-acted as a mediator in the linkage between the devaluation of the currency and the expansion of the economy from 1972 to 2016. All the variables have been shown to have a heterogeneous order of integration by using the Augmented Ducky Fuller (ADF), Phillips-Perron (PP), and Ng-Parron unit root tests. As shown in this article, the Auto regressive Distributive Lag Model (ARDL) is used to figure out how the variables are linked. The results clearly demonstrate that the current account balance fully mediates the relationship between devaluation of the currency and economic growth with a coefficient value of -0.12. Findings show that devaluation of the currency negatively affects the current account balance and economic growth. Moreover, through an indirect channel,the devaluation negatively affects the current account balance, which hampers economic growth.

Karachi is the world's fastest expanding metropolis, and it ranks among the world's largest cities. The disparity between public and private transportation utilization in Karachi is growing by the day. To address this imbalance, private automobile users must change to more environmentally friendly modes of transportation. A travel behavior study is required to shift people's mode of transportation from private to public transportation. As a result, the emphasis of this study is on the impact of socioeconomic determinants on employee mode choice in Karachi. A survey was done using a self-administrative quantitative questionnaire to acquire information on travel habits. To examine the data, descriptive-analytic tests were used in SPSS. The study's findings leaned more toward the use of private transportation. There is no such thing as a beneficial influence of socioeconomic characteristics on public transit use. This study might provide helpful information to stakeholders for future planning and development of sustain able transportation techniques in Karachi. The research findings will aid policy making and serve as the foundation for future research on the mode choice model for P and RS.

Teachers having effective follower ship styles are considered crucial for school success.However, school leaders are frequently observed complaining about the reluctant behavior of many teachers in fulfillment of their professional responsibilities, which indicates the lack of teachers having an effective follower ship style. Therefore, the study investigated the proportion of teachers in terms of their follower-ship styles, i.e. exemplary, conformist, pragmatic, passive, and alienated. A survey was conducted to obtain data from 1209 teachers selected through the two-stage random sampling technique. Data was collected using a self-developed scale to assess the teachers' follower-ship. Results revealed that pragmatic followers are highest in number and alienated are the lowest. However, teachers having exemplary follower-ship styles are at the fourth number with less than the desired proportion.Hence, authorities of teachers' recruitment and professional development may sufficiently focus on effective follower ship styles among the teachers.

Introduction: Chronic suppurative otitis media (CSOM) is middle ear infection, perforation and inflammation usually with purulent middle ear discharge. Different immune markers such as IgE and interferon were proved to be elevated in CSOM. Aim/Objective: The aim of the study is to evaluate of these inflammatory biomarkers (IL6, IL8 and TNF gamma) in patient of CSOM to suggest future therapy of chronic infections with inflammations. Methodology: This is a case-control study conducted in ENT ward in a tertiary care hospital in Jinnah Post Medical centre, Karachi during November 2017 to May 2018. Patients or healthy volunteers were divided into two groups as G1 (without any disease) and G2 (CSOM patients without treatment), G3 (CSOM patients treated with co-amoxicillin) and G4 (CSOM patients treated with ciprofloxacin). The serum was subjected for the quantitative measurement of IL6, IL8 and TNF Gamma by ELISA Kit method via antibody-antigen-enzyme complex formation and measured at 450 nm. Result: Study shows that IL6, IL8 and TNF gamma concentration was significantly high in G2 (positive control), G3 (ciprofloxacin) and G4 (co-amoxicillin) in contrast with G1 (negative control). Moreover, IL6 concentration was significantly low in G3 (ciprofloxacin) and G4 (co-amoxicillin) as compare to G2 (positive control). Conclusion: Elevated levels of IL6, IL8 and TNF gamma in CSOM showed alteration of immune response in chronic suppurative otitis media. Moreover, anti-inflammatory role of ciprofloxacin and co-amoxicillin in CSOM may provide additional benefit beside attenuation of infection.
