Flexible multiferroic composite films are perspective materials for sensors, actuators and similar components of wearable and stretchable devices. Here we present the study of functional properties of flexible composites prepared by embedding nickel zinc ferrite and barium titanate powder into polyvinylidene fluoride (PVDF) polymer optimizing the ratio of polymer and fillers to get the best flexibility and functionality. ATR-FTIR analysis revealed that hot pressing of the flexible films caused a transformation of about 38% of the electro-inactive PVDF α phase into electrically active β and γ phases. Broadband dielectric spectroscopy revealed two relaxation processes responsible for PVDF and space charge relaxations. Activation energies of both processes and the freezing temperature of PVDF to the glass phase were estimated for all films. Ferroelectric measurements have shown unsaturated hysteresis loops for all samples, although the clear dependence of the amount of the electrically active phase on polarization values of composites is visible.

Authors: Martínez-Monedero Miguel , Vergara-Muñoz Jaime
Published: December 2022

La medina de Tetuán (Marruecos, Patrimonio de la humanidad de la UNESCO, 1997) mantiene en pie aproximadamente las dos terceras partes de sus murallas. Levantadas en origen en el s. XVI, fue en el s. XVIII cuando se dio forma definitiva a la estructura que, con ligeras modificaciones, ha llegado a nuestros días. En ella destacan, por su carácter monumental y defensivo, las siete puertas de acceso a la medina. Este artículo aporta un estudio constructivo y formal de estas últimas, desarrollado mediante el trabajo in situ con métodos habituales para el levantamiento gráfico y toma de datos arquitectónica. El objetivo es dar a conocer este valioso patrimonio, además de generar un material nuevo que pueda servir de base documental para futuras campañas de conservación. Se aportan los levantamientos en altura y las secciones de las siete puertas.

Published: December 2022

The 2019–2023 Masterplan for Kent County Parks includes the future development of acquired properties that have been designated as the Lowell Regional Greenspace (528 acres), occupying nearly the entirety of Section 22 of Lowell Charter Township in Kent County, Michigan. Four wetlands located in the same drainage basin along Karen Creek in the Lowell Regional Greenspace were inventoried for floristic quality assessments during the summers of 2016, 2018, 2019, and 2021. One of the wetlands was forested and determined to be a southern hardwood swamp community type. The other three wetlands are best classified as shrub-carr communities. In the southern hardwood swamp, we recorded 94 species, of which 87 (92%) are native. A total of 321 species were documented in the three shrub-carrs wetlands combined. The number of species in each shrub-carr site, ranging from 172 to 238, is roughly twice that for the southern hardwood swamp site. Two of the species documented are listed as Special Concern in Michigan, and two are new county records for Kent County, Michigan. A non-metric multidimensional scaling model (NMDS) was run to spatially compare similarities and differences among the sites. The Sørensen Index of Similarity, which was employed to further discern differences between pairs of individual sites, was also useful for assigning plant community types as described by the Michigan Natural Features Inventory (2016). The Floristic Quality Assessments indicate that all four of the wetlands are floristically important statewide; furthermore, the three shrub-carr communities have exceptional conservation value. We discovered that the three shrub-carr sites have a high degree of similarity in their species assemblages, whereas the southern hardwood swamp was markedly different. The high richness and significant floristic quality of the shrub-carr sites highlight the conservation value of these often-overlooked habitats. This study underscores the importance of preserving even small tracts of persisting remnant natural habitats. Our research should be of use to Kent County Parks as they approach development of the Lowell Regional Greenspace into a multiple-use recreational space, as well as to those interested in learning more about how to assess and compare habitat quality of remnant natural areas.
Low complexity hybrid layered tabu‐likelihood ascent search for large MIMO detection with perfect and estimated channel state information
Authors: Chakraborty Sourav , Sinha Nirmalendu Bikas , Mitra Monojit
Published: December 2022

In this work, we proposed a low‐complexity hybrid layered tabu‐likelihood ascent search (LTLAS) algorithm for large multiple‐input multiple‐output (MIMO) system. The conventional layered tabu search (LTS) approach involves many partial reactive tabu searches (RTSs), and each RTS requires an initialization and searching phase. In the proposed algorithm, we restricted the upper limit of the number of RTS operations. Once RTS operations exceed the limit, RTS will be replaced by low‐complexity likelihood ascent search (LAS) operations. The block‐based detection approach is considered to maintain a higher signal‐to‐noise ratio (SNR) detection performance. An efficient precomputation technique is derived, which can suppress redundant computations. The simulation results show that the bit error rate (BER) performance of the proposed detection method is close to the conventional LTS method. The complexity analysis shows that the proposed method has significantly lower computational complexity than conventional methods. Also, the proposed method can reduce almost 50% of real operations to achieve a BER of 10−3.
The Impact of Emerging Plasmodium knowlesi on Accurate Diagnosis by Light Microscopy: A Systematic Review and Modeling Analysis
Authors: Huber John H. , Elliott Margaret , Koepfli Cristian , Perkins T. Alex
Published: December 2022

The five major Plasmodium spp. that cause human malaria appear similar under light microscopy, which raises the possibility that misdiagnosis could routinely occur in clinical settings. Assessing the extent of misdiagnosis is of particular importance for monitoring P. knowlesi, which cocirculates with the other Plasmodium spp. We performed a systematic review and meta-analysis of studies comparing the performance of microscopy and polymerase chain reaction (PCR) for diagnosing malaria in settings with co-circulation of the five Plasmodium spp. We assessed the extent to which co-circulation of Plasmodium parasites affects diagnostic outcomes. We fit a Bayesian hierarchical latent class model to estimate variation in microscopy sensitivity and specificity measured against PCR as the gold standard. Mean sensitivity of microscopy was low, yet highly variable across Plasmodium spp., ranging from 65.7% (95% confidence interval: 48.1–80.3%) for P. falciparum to 0.525% (95% confidence interval 0.0210–3.11%) for P. ovale. Observed PCR prevalence was positively correlated with estimated microscopic sensitivity and negatively correlated with estimated microscopic specificity, though the strength of the associations varied by species. Our analysis suggests that cocirculation of Plasmodium spp. undermines the accuracy of microscopy. Sensitivity was considerably lower for P. knowlesi, P. malariae, and P. ovale. The negative association between specificity and prevalence imply that less frequently encountered species may be misdiagnosed as more frequently encountered species. Together, these results suggest that the burden of P. knowlesi, P. malariae, and P. ovale may be underappreciated in a clinical setting.

Meme kanseri, kadınlarda sık görülen ciddi bir kronik hastalık olarak tanımlanır. Meme kanseri, kanser kaygısı ve korkusunun yanı sıra kadınlar için önemli bir sembolik imajın kaybolmasına neden olabilir. Bu çalışma, mastektomi operasyonu geçiren kadınların hastalık sırasında ve sonrasında yaşadıkları duygusal deneyimlerini ortaya koymak ve fotoses yöntemi ile maktektominin benlik saygılarına etkisini değerlendirmek amacıyla yapılmıştır. Mastektomi geçiren bireylerin psikolojik, ruhsal, fiziksel ve sosyal sorunları, fotoğraf ve açıklamalarıyla birlikte analiz edilmiştir. Bu çalışmaya yaşları 42 ile 67 arasında değişen mastektomi operasyonu geçirmiş 14 kadın katılmış ve deneyimlerini anlatan 45 fotoğraf elde edilmiş, 23 fotoğraf yorum zenginliği ve maksimum çeşitlilik dikkate alınarak aşamalı olarak analiz edilerek değerlendirilmiştir. Tematik analiz kullanılarak katılımcılar tarafından çekilen fotoğraflar için bir kod listesi oluşturulmuş ve kodlar birleştirilerek temalar ortaya çıkarılmıştır. Yapılan analizler, mastektomi operasyonu ile birlikte kadınlığı temsil eden önemli bir organın kaybedilmesinin, kadınların toplum tarafından damgalanacağına olan inancını artırdığını ve benlik saygısının azalmasına bağlı olarak birçok psiko-sosyal sorunu beraberinde getirdiğini göstermiştir.
Felsefe ve Sûfî Perspektiften Mutluluk Bilgeliği
Authors: KIZILER Hamdi , ÖKSÜZOĞLU Şerife
Published: December 2022

İnsan, var olduğu ilk çağlardan bu yana kendisi için iyi bir yaşama ulaşmanın imkânını sorgulamıştır. Varoluşsal amacını bu “iyi” ile ilişkilendirmiş, iyiye ulaşmayı mutlu olmak hedefiyle birlikte değerlendirmiştir. Mutluluk insan temalı tüm disiplinlerde; eylem, bilgi ve ahlâk örüntüsünü takip eder şekilde tartışılmıştır. Bu bağlamda mutluluk, ontolojik olarak insanın temel hedefleri arasında yer almıştır. Ancak bu husus her zaman aynı bilinç ve anlayışla sürdürülememiştir. Nitekim son dönemlerde özellikle de modern zamanlarda insanın bu odak noktasını kaybettiği görülmekte, mutluluğun kavramsal tahlilinin yatay düzlemde ele alındığı ve öz anlamının daraltıldığı gözlemlenmektedir. Bu çalışmanın amacı, mutluluk anlayışında felsefe ve tasavvuf düşüncelerinin insan ve eylemleri ile ahlâk arasındaki bağlantısına dikkat çekmek, disiplinler arası benzerlik ve farkları ortaya koyarak insan yaşamının nihai amacı ve motivasyonu üzerine bir ufuk oluşturmaktır. Mutluluk gibi bir varoluşsal erdemin insanlık kadar uzun bir geçmişi ve genişliği olduğu dikkate alınarak konunun sınırlandırılması uygun görülmüştür. Bu sebeple insanlık ve düşünce tarihi açısından önemli birer değer kabul edilen filozof Aristoteles ve sûfî Mevlânâ’nın düşünceleri, çalışmanın temel unsurlarını oluşturmuştur. Düşünürlerin görüşleri içerik analizine tabi tutularak incelenmiş ve değerlendirilmiştir.

Amaç – Bu çalışmanın amacı, hizmetkâr liderliğin kurumsal kültür üzerindeki etkisini incelemektir.

Yöntem – Çalışmanın örneklemini özel bir belgelendirme firmasında çalışan 266 personel oluşturmaktadır. Anket verileri SPSS programı ile analiz edilmiştir.

Bulgular – Hizmetkâr liderliğin kurumsal kültürü pozitif yönde anlamlı etkilediği bulunmuştur. Sonuçlar, Hizmetkâr liderliğin affetme, hesap verebilirlik, otantiklik, geride durma ve cesaret boyutlarının kurumsal kültürü etkilemediğini göstermiştir.

Tartışma – Kurum kültürünü temel dinamikleri ve hizmetkâr liderlik üzerindeki etkisi incelenmiştir. Örgüt kültürü, ülke kültürü ve alt kültürler farklılık göstermektedir. Aynı kurumda bile satış görevlileri ayrı mühendisler ayrı bir kültürü paylaşmaktadır. Bu yüzden bir kurumun kültürünü tanımlamak ve nasıl algılandığını belirlemek oldukça zordur.

Machine Learning based Frame Size Optimization in WLAN Downlink MU-MIMO Channel with the Least Cost of Delay
Authors: Kassa Lemlem , Deng Jianhua , Davis Mark , Cai Jingye
Published: December 2022

The key enhancement in the medium access control (MAC) layer is frame aggregation introduced by the IEEE 802.11n/ac standard to accommodate the growing traffic demand in the WLAN by allowing multiple packets aggregated per transmission. Frame aggregation efficiently reduces control overhead in the MAC layer, such as the MAC header and thus it helps to enhance transmission efficiency and throughput performance of WLAN. However, heterogeneous traffic demand among streams in the WLAN downlink MU-MIMO channel creates a challenge to efficiently utilize the benefits of frame aggregation. Transmission efficiency is also compromised during frame size setting determination because when a frame size is larger, the impact of the overhead frame can be lower, but they are also more vulnerable to transmission errors. Thus, this trade-off between maximizing frame size and minimizing overhead frames should be addressed by employing an adaptive frame aggregation technique to derive the optimal frame size that would maximize the throughput in WLAN downlink MU-MIMO channel. Moreover, when frame aggregation approach is employed, more frames must wait before transmission in a buffer which causes a delay in the performance of WLAN. Thus, analysing the trade-off between maximizing throughput and minimizing delay is a critical issue that should also be addressed to enhance the performance of WLAN. However, the majority of the existing adaptive aggregation algorithms in the WLAN downlink MU-MIMO channel are focused to maximize the throughput or minimize the delay. The main contribution of this paper is to propose a machine learning-based frame size optimization algorithm by extending our earlier approach in considering the cost of delay to maximize the system throughput of WLAN. The effectiveness of the proposed scheme is evaluated over the FIFO Baseline Approach and earlier conventional approaches under the effects of various traffic patterns, channel conditions, and the number of STAs.
Efficient Scrambling-Substitution Image Security Scheme using Chaotic Arnold-Logistic Maps in the Discrete Cosine Transform
Authors: A. AlZain Mohammed
Published: December 2022

This paper introduces an efficient scrambling-substitution image security scheme using chaotic Arnold and Logistic (Arnold-Logistic) maps in the discrete cosine transform (DCT). The Arnold map is employed as a scrambling stage while the Logistic map is employed as a substitution stage. The hybrid Arnold-Logistic mapping is performed in the DCT. The encipherment phase of the introduced DCT-based Arnold-Logistic security scheme begins by applying the DCT to the plainimage and the resulted DCT coefficient of the plainimage are scrambled for m iterations using the Arnold transformation. Then, the Arnold-based transformed DCT coefficients are substituted for n iterations using the Logistic map and the inverse of DCT (IDCT) is employed to produce the cipherimage. The decipherment phase of the introduced DCTbased Arnold-Logistic security scheme is the inverse of the encryption stage and begins by applying the DCT to the cipherimage. The resulted DCT coefficient of the cipherimage is inversely substituted for n iterations using the inverse Logistic map. Then, the inverse Logistic-based transformed DCT coefficients are inversely scrambled for m iterations using the inverse Arnold map and the IDCT is employed to produce the decrypted image. A series of test experiments are applied to investigate the introduced DCTbased Arnold-Logistic security scheme. The outcome results demonstrated the superiority of the introduced DCT-based Arnold-Logistic security scheme from the security point of view.

Published: December 2022

Este estudio transversal tuvo como objetivo identificar los perfiles de adicción a las redes sociales y si existe relación con las necesidades psicológicas básicas, el autoconcepto y la intención de ser físicamente activo. Participaron 276 estudiantes (115 hombres y 161 mujeres, Medad= 28,47; DT= 8,65) de 10 universidades españolas en un muestreo intencional. Se encontraron dos perfiles, uno caracterizado por puntuaciones altas en síntomas de adicción, uso social, uso friki y nomofobia, y otro caracterizado por puntuaciones extremadamente altas en síntomas de adicción, uso social, uso friki y nomofobia. Los resultados revelaron diferencias significativas en: autonomía, competencia y autoconcepto emocional. El segundo perfil mostró puntuaciones más bajas en todas esas medidas y tenían menor edad (M= 25,69; DT= 6,93) que los del primer perfil (M= 30,10; DT= 9,15). La presencia de niveles importantes de síntomas de adicción en ambos perfiles de la muestra sugiere crear intervenciones para prevenir los resultados desadaptativos de las adicciones en las redes sociales.

Published: December 2022

Abstract. Compound-specific hydrogen isotopes are increasingly used as a powerful proxy for investigating biogeochemical cycle and climate change over the past two decades. Understanding the hydrogen isotope in extant organisms is fundamental for us to interpret such isotope signals preserved in natural environmental samples. Here, we studied the controls on hydrogen isotope fractionation between fatty acids and growth water by a Fe-reducing heterotrophic marine bacterium Shewanella piezotolerans WP3 growing on different organic substrates, including N-acetyl-D-glucosamine (GlcNac), glucose, acetate, pyruvate, L-alanine and L-glutamate. Meanwhile, we also evaluated the impact of growth temperature on the hydrogen isotope composition of fatty acids using GlcNac as sole organic substrate. Our results show that the abundance-weighted mean fatty acids/water fractionations (εFA/Water) display considerable variations for cultures grown on different substrates. Specifically, WP3 yielded the most 2H-enriched fatty acids growing on L-glutamate and pyruvate with εFA/Water of 52 ± 14 ‰ and 44 ± 4 ‰ respectively, and exhibited 2H-depleted using GlcNac (-76 ± 1 ‰) and glucose (-67 ± 35 ‰) as sole carbon sources, relatively small fractionations on acetate (23 ± 3 ‰) and L-alanine (-4 ± 9 ‰). Combined with metabolic model analysis, our results indicate that the central metabolic pathways exert a fundamental effect on the hydrogen isotope composition of fatty acids in heterotrophs. Temperature also has obvious influence on the δ2H values of fatty acids, with strongly 2H-depleted at optimal growth temperature (15 and 20 °C) and relatively small fractionations at non-optimal temperatures (4, 10, and 25 °C). We hypothesized that it is most likely controlled by the temperature effects on the activity of associated enzymes for NADPH production. This study helps understanding the controlling factors of hydrogen isotope fractionation by marine bacteria, lays the foundation for further interpreting the hydrogen isotope signatures of lipids as an important proxy to decode the biogeochemical cycles and ecological changes in marine sediments.
Updated Isoprene and Terpene Emission Factors for the Interactive BVOC Emission Scheme (iBVOC) in the United Kingdom Earth System Model (UKESM1.0)
Authors: Weber James , King James A. , Sindelarova Katerina , Val Martin Maria
Published: December 2022

Abstract. Emissions of biogenic volatile organic compounds (BVOCs) influence atmospheric composition and climate and will be influenced by future changes in land use and land cover (LULC) and change. Climate and Earth System Models typically calculate emissions using parameterisations involving surface temperature, photosynthetic activity, CO2 and the type of vegetation present. The influence of vegetation is described by assigning emission factors (EF) to different types of vegetation simulated in the model. We detail calculations of new EF for the Interactive BVOC Emission Scheme (iBVOC) used in the United Kingdom Earth System Model (UKESM). These EFs are based on those used by the Model of Emissions of Gases and Aerosols from Nature (MEGAN) v2.1 scheme. We present these EFs as alternatives to the current EFs used in iBVOC which are derived from older versions of MEGAN and the Organizing Carbon and Hydrology in Dynamic Ecosystem (ORCHIDEE) emission scheme. The EFs currently used by iBVOC include an oversimplification which incorporates the EF of shrubs (high isoprene emitters) into the EFs for C3 and C4 grasses (low isoprene emitters) despite UKESM1 treating grasses and shrubs separately. Thus, the current approach significantly overestimates the isoprene emissions from grasses, particularly C4 grass which is responsible for 40 % of total simulated isoprene emissions in the present day, much higher than other estimates of ~0.3–10 %. The new isoprene EF calculated in this work substantially reduce the amount of isoprene emitted by C4 grassland, in line with observational studies and other modelling approaches, while also increasing the emissions from known sources such as tropical broadleaf trees. Similar results are found from the change to terpene EF. The total global isoprene and terpene emissions with the new EF are in the range suggested by literature. The existing model biases in isoprene column are slightly exacerbated with the new EFs although other drivers of this bias are also noted. The disaggregation of shrub and grass EFs should lead to a more faithful description of the contribution to BVOC emissions from different vegetation types, critical for understanding BVOC emissions in the pre-industrial and under different future LULC scenarios such as those including wide scale reforestation or deforestation.

Eagle's syndrome or styalgia is characterised by the anatomical bone deformity of the styloid process, as identified by Wat W. Eagle in 19491. An aggregate of symptoms caused by the elongation and severe calcification of the temporal bone's styloid process, as well as calcification of the ligaments attached to this process, including the styloid and stylomandibular ligaments, have been identified2. The styloid process is typically 20 to 30 mm in length, and patients with elongated styloid processes of 40 mm or longer have clinical distress 1,3 . This styloid process elongation could be unilateral or bilateral 4. It affects around 4% of the general population, with 3:1 female predominance, however only 4% of these people experience associated symptoms 3. Eagle mainly characterized two syndromes: “classic styloid syndrome” following tonsillectomy, and “stylocarotid syndrome” unrelated to tonsillectomy6. The “styloidogenic jugular compression syndrome”, a third variation of Eagle syndrome, was recently identified, in which the jugular vein is squeezed, resulting in cerebral venous hypertension and, most commonly, headaches1.

La'bo 'Village is one of the villages in North Toraja Regency. It is located about 8 km from the city of Rantepao. The people live as farmers. In addition, generally every household raises livestock in a pen at the back of the house. Manure from each livestock pen is disposed of freely, causing an unhealthy odor around the house. To solve the pollution problem, a training was conducted for the La'bo 'community to build a biogas installation as a tool to properly process livestock manure and provide added value to the community. To build a biogas installation, training is carried out using the on-job training method. The community is invited to work directly to build the installation together so that they can receive the knowledge and skills from this waste treatment technology. The training to build a biogas installation was carried out in collaboration with the Marante Tampang Allo Farmer Group and the Biang Farmer Group. From this training, the community has gained knowledge and skills to build and manage livestock waste into biogas. The result of this collaboration with farmer groups has succeeded in building 2 units of biogas installations with a capacity of 4 m3 of the fixed dome type. With the construction of the biogas installation, the air pollution around the house becomes healthier and the demand for LPG for each household has been replaced by biogas produced from the biogas installation

Published: December 2022

Organik çay tarımı tüm üretim sezonu boyunca kimyasal ilaç ve gübre kullanılmayan, işleme sürecinde ise çayın organik yapısında bozulmaya sebebiyet verecek işlemlere tabii tutulmayan ve hiçbir surette sentetik katkı maddesi içermeyen organik tarım mevzuatına uygun üretilen ve işlenen çay olarak tanımlanmaktadır.

Türkiye’de çay tarımında organik tarım faaliyetleri ÇAYKUR tarafından 2003 yılında başlanmıştır. Bu tarihte Rize ili Çamlıhemşin ve Hemşin, Artvin ili Borçka ilçelerinde organik çay havzası seçilen alanda 135 üretici ile organik çay tarımı sözleşmeleri imzalanarak 378 dekarlık çaylıkta organik çay projesi başlatılmıştır. 2009 yılında Rize ili Hemşin ilçesinde ilk organik çay fabrikası kurulmuş organik tarım sözleşmesine uygun olarak üretilen çaylar işleme alınmıştır.

Türkiye, dünyada en fazla çay tüketen ülkeler sıralamasında açık ara farkla birinci sırayı almaktadır. Ekosistemde meydana gelen kirlenmeler ve bilinçsiz sentetik gübreleme ve ilaçlama yapılan konvansiyonel tarım alanlarında yetişen ürün içeriklerinde meydana gelen kalıntı miktarındaki artış sebebiyle organik ürünlere talep artmıştır. Bu artışa ve bilinçlenmeye binaen birçok organik üründe olduğu gibi çayda da organik ürüne eğilimi artmaya başlamıştır.

Bu çalışma, ülkemizde çayın organik olarak yetiştiriciliğinin başlamasından günümüze kadar olan süreçte üretim, işleme ve pazarlama durumu hakkında bilgi vermektedir.

Published: December 2022

The aim of this study is to analyze and compare the effects of trust in top management on turnover intention and affective commitment of airline personnel in Turkey and Europe and to test whether trust in top management has a mediating effect on the relationship between top management communication and turnover intention and between top management communication and affective commitment of airline employees. Another aim of this study is to test whether trust in top management has a moderating effect on the relationship between perceived job stress and turnover intention. Based on the data obtained from a sample of 729 airline personnel working in Turkey and Europe, the findings reveal that trust in top management has a full mediating effect on the relationship between top management communication and turnover intention and between top management communication and affective commitment. Moreover, the results reveal that trust in top management moderates the relationship between perceived job stress and turnover intention for the Turkish sample. Based on the findings of this study, managerial and practical implications are provided.

Maps and Crime. Literary Maps and the Meaning of Places in Crime Series for Children

In literature, and especially in crime fiction, the site of the action and the crime itself are often as crucial an element for the story as the main characters. Most theoretical approaches to crime literature have been primarily concerned with discussing genre typologies on the basis of the plot, the investigator and the investigation. Less attention has been paid to the landscape of crime fiction in both theory and analysis. In this article, I will discuss two series: Bjørn Sortland’s Art Detective Series and Martin Widmark and Helena Willis’ Whodunit Detective Agency Series. These very popular series have been chosen as examples because all the books in the series provide the readers with a map of the location of the action. In addition, both series are classified as chapter and young reader books. This means that the maps may provide strategic reading support for young and often inexperienced readers.

Maps are not an uncommon peritextual phenomenon in books for children, and the maps in the series discussed here are therefore initially considered in the context of other maps in children’s literature. The article goes on to discuss how the maps and the places function as important tension-reinforcing elements in crime novels, and also as an expression of the mystery genre and the society the series represents.
Comparative Assessment of Solar Energy Based Transcritical CO2 Rankine Cycles for Different Layouts
Authors: ÇELİK TOKER Serpil , KIZILKAN Önder
Published: December 2022

In this study, different transcritical CO2 Rankine (tCO2-RC) cycles with vacuum tube solar collectors are examined. In this context, the transcritical CO2 Rankine cycle in different configurations, such as simple, regenerator, reheat, regenerator, and reheat, which is widely used in the literature, has been chosen. First, the energy and exergy efficiencies of the cycles were founded by performing thermodynamic analyzes of four various tCO2-RCs under certain operating parameters. Moreover, parametric studies were carried out according to the factors affecting the system performance, like turbine input temperature and input pressure of the turbine. Both analyzes and parametric studies were conducted utilizing the Engineering Equation Solver (EES) computer program. As outcomes of analyzes, the highest thermal efficiency was founded for the tCO2-RC with reheat and regenerator by 11.8%, and the lowest energy efficiency was calculated for the simple tCO2-RC and tCO2-RC with reheat by approximately 6.6%. While all tCO2-RCs' energy and exergy efficiencies increased with the rise of the turbine’s input pressure, the energy and exergy efficiency of all tCO2-RCs decreased with the rise of the pump’s input pressure.

Classical swine fever (CSF) is an economically important pig disease affecting rural pig farming and vaccines are not freely available for control. In the present study an Indian isolate of CSF virus was passaged 75 times in PK-15 cells. At different passages, presence of virus was confirmed by Fluorescent Antibody Virus Neutralization (FAVN) test and Reverse Transcription-Polymerase Chain Reaction (RTPCR) for NS5B, E2 and 5-UTR genes. TCID50 titers were found to range between 4.00 and 8.97 at 10th and 75th passages respectively. Back passage and pathogenicity studies in susceptible pigs, the natural host, indicated that the virus was found to be attenuated following PK-15 passages and did not produce any clinical signs after 45th and 75th passages.
In vitro evaluation of kinnow waste as substitute of cereal grains in the concentrate mixture and empty pea pods as that of berseem hay in total mixed ration for livestock

This study was taken up to assess the extent to which kinnow mandarin (Citrus reticulata) waste (KW) could substitute cereal grains in the concentrate mixture and empty pea (Pisum sativum) pods (EPPs) as that of berseem (Trifolium alexandrium) hay in total mixed ration (TMR) for livestock. In the first experiment, sundried finely ground kinnow waste replaced barley grains on N basis at 0, 25, 50, 75 and 100% levels in concentrate mixtures. The comparable N-content indicated that the concentrate mixtures were iso-nitrogenous. The EE and cell wall constituents (CWC) increased linearly with the increase in level of KW. The replacement of barley with KW did not affect net gas production (NGP), true OM digestibility and ME availability up to 50% level of replacement. Total and individual volatile fatty acids (VFAs) and microbial biomass production improved up to 50% level of replacement but declined thereafter. In the second experiment, sundried finely ground EPPs replaced berseem hay on N basis at 0, 25, 50, 75 and 100% levels in TMR. The EE and CWCs content was not affected up to 50% level but thereafter EE content decreased, whereas CWCs content increased. The NGP, digestibility of true DM and OM, VFAs production, ME availability and microbial biomass synthesis improved up to 50% level of replacement of berseem hay with EPPs, thereafter it declined. The hydrogen recovery, hydrogen consumption and fermentation efficiency were not affected upto 50% level of EPPs but at higher levels these parameters were depressed. Therefore, KW could replace barley grains in concentrate mixture while EPPs could replace berseem hay in TMR up to 50% level without affecting nutrient utilization, VFA production, ME availability and microbial biomass production under in vitro conditions.
