Student Experience and Ethnic Diversity: The Experiences of Underrepresented Minority Students at a Veterinary University in the United Kingdom
Authors: Chung Grace H. , Armitage-Chan Elizabeth
Published: May 2021

Despite a lack of diversity, studies on the experience of ethnically diverse (ED) students have not focused on veterinary education. This study used focus groups to explore the experience of ED veterinary students, their challenges, and their sources of support in this setting. Focus groups were held using two formats: a traditional, in-person approach, and online, via a social media group. Recruitment was by invitation and focus group allocation according to participant preference. Conversations were transcribed or downloaded, anonymized, and analyzed using a two-part narrative analysis, the aim of which was to understand the experiences of ED veterinary students at an in-depth level. Students experienced identity conflicts at multiple levels (self, others, profession), which appeared to relate to their ethnicity. Conflict between self and others resulted in a feeling of otherness arising from a White student majority, both within the university and on external placements, and professional identity conflicts arose between students’ personal cultural values and their values as a veterinarian. Internal conflicts arose when students felt a wish to integrate but also perceived a need to segregate with similar others to obtain support and a sense of belonging to a group. These challenges have potential implications for mental well-being and career opportunities. For veterinary medicine to adapt to changing client demographics in an increasingly globalized world, a deeper understanding of the ED student experience may offer advantages in areas such as recruitment and profession retention, which will eventually support greater diversity within the professional population.

Published: May 2021

O processo de globalização auxiliou na internacionalização de alguns processos produtivos de empresas. Com isso, algumas organizações, como as concessionárias de automóveis, terceirizaram processos como a comercialização do seu produto final. A promoção de vendas é um componente do mix de marketing que auxilia na venda dos produtos finais no curto prazo. O objetivo deste trabalho é verificar quais as estratégias de promoção de vendas utilizadas pelas concessionárias autorizadas, e de quem é a autonomia para realizar essas ações. Para isto, foi realizado um estudo qualitativo, com a estratégia de estudo de caso e a utilização de entrevista semiestruturada. A amostra é composta por cinco concessionárias de automóveis de diferentes montadoras. Os resultados revelam que as concessionárias utilizam diferentes estratégias de promoção de vendas, cada uma com sua finalidade. A autonomia para realização das ações de promoção de vendas pode ser da montadora, da concessionária, ou de ambas. Este estudo desenvolve a literatura e as pesquisas empíricas sobre as cadeias globais de valor e auxilia na compreensão do funcionamento da cadeia da indústria automobilística.

Published: May 2021

Introduction : La simulation est un outil d’enseignement en médecine qui a montré un bénéfice entre autres pour l’apprentissage de la réanimation cardiopulmonaire (RCP). Cependant, la RCP simulée peut différer grandement de la RCP en conditions réelles. Le but de cette étude exploratoire était d’identifier des éléments perturbateurs susceptibles d’intervenir lors d’une RCP.

Méthodes : Il s’agit d’une étude transversale anonyme par questionnaire distribué par courrier électronique aux urgentistes de cinq services d’urgences à Paris. Le questionnaire comprenait des questions sur les éléments perturbateurs lors d’une RCP. D’autres questions ont exploré les différences perçues entre la RCP simulée et la RCP réelle. Les résultats sont exprimés sous forme de pourcentages et moyennes (± écart-type).

Résultats : Sur 100 médecins interrogés, 43 (43 %) réponses ont été analysées. Cinquante-trois pour cent étaient des femmes âgées en moyenne de 32 ± 3 ans. Les éléments perturbateurs de la RCP dans la vie réelle étaient principalement les interruptions de tâches provenant du personnel non médical (n = 16 ; 37 %), de la famille du patient (n = 5 ; 12 %), des autres spécialistes (n = 5 ; 12 %) et des appels téléphoniques (n = 2 ; 5 %). La saturation du flux patient des urgences (n = 12 ; 28 %) a également été mentionnée comme perturbateur. Les médecins ont aussi déclaré que certaines compétences techniques et non techniques étaient plus difficiles à réaliser dans la vie réelle que lors de simulations.

Conclusion : Cette étude exploratoire a permis d’identifier des éléments perturbateurs rencontrés dans des cas réels de RCP qui pourront être intégrés aux sessions de simulation afin d’en augmenter le réalisme.

Brain Drain in Africa: Issues and Challenges in the Context of Higher Learning in Cameroon
Authors: Fru Raymond Nkwenti
Published: May 2021

The so-called brain drain is a topical issue globally, and especially in Africa, where the phenomenon is multifaceted. Inspired by similar trends reported for Africa, this conceptual paper highlights the case of Cameroon by exploring the structure of academic staff recruitment by state universities, which is managed through a highly centralised bureaucratic public service system. The tendency to appoint people to key university positions, such as vice rectors, deans, and heads of departments, by presidential decree exacerbates the situation. In addition, the limitation of 45 years as the maximum entry age into the public service deprives universities of highly skilled professionals, who seek employment elsewhere although they have the potential to contribute to the development of the economy through involvement in the local higher education system. To mitigate this situation, it is imperative for governments to separate state universities from the broader public service system, and grant the universities autonomy to manage their own affairs, including recruitment based on their peculiar realities. Giving universities the authority to manage their own recruitment and promotion processes will encourage competition, boost output and reputation, and curb brain drain
UČENJE FRANCUSKOG JEZIKA (L2) I MEĐUJEZIK – STUDIJA SLUČAJA
Authors: Špadijer Sonja
Published: May 2021

Tokom procesa učenja L2, studenti stvaraju sistem apstraktnih jezičkih pravila koja omogućavaju razumijevanje i produkciju na L2. Taj sistem pravila smatra se mentalnom gramatikom (Elis 1997, 33) i nosi naziv međujezik (Interlanguage) (Selinker 1972; 1975). Međujezik predstavlja fazu u procesu učenja L2 koja pomaže učenicima da mentalno restrukturiraju nova znanja, nove oblike, strukture i funkcije koje upravo uče. Jezik kojim se služe studenti nije samo rezultat razlika između jezika koje već znaju i jezika koji uče, već je riječ o cjelovitom i potpunom jezičkom sistemu koji ima sopstvena pravila. Strukture koje nastaju u okviru međujezika nijesu proizvoljne. U ovom radu, moj cilj je da opišem karakteristike jezika (L2) kojim govore studenti prve i završne godine studija francuskog jezika i književnosti, da objasnim šta to govori o prirodi njihovog znanja i na koji način se njihov međujezik razlikuje od norme standardnog francuskog jezika. Da bih postigla zadati cilj, u okviru studije slučaja, proučavaću kako se kod studenata razvija sposobnost da produkuju određene gramatičke strukture. Opisaću uočene greške koje studenti prave, objasniću ih, procijeniti po metodologiji Teorije usvanja L2 – SLA (Elis 1997, 16–23). Na osnovu elemenata koji karakterišu međujezik studenata prve godine i međujezik studenata četvrte godine, ustanoviću kako su se razvijali. Rezultati istraživanja imaće primjenu u redefinisanju nastavnih ciljeva i aktivnosti
DEFORMATION OF A CULTURAL MODEL IN THE ANTI-WAR NOVEL
Authors: Labudović Tamara
Published: May 2021

In the novel Hero on a Donkey, Miodrag Bulatovic dealt with the theme of war according to the principle of Menippean satire, without epic sublimity, distancing himself and denying mythic value by creating an antihero. Such a radical critical attitude toward literary tradition is the result of the activation of the carnival and grotesque code. The war chronotope, which always appeared in Montenegrin literature as an extremely fruitful soil for emphasizing the moral purity and firmness, integrity and sacrifice of a Montenegrin woman, enabled Bulatovic to distort female characters under the prevalence of carnival imagination that does not know the limitations. The characters in this novel represent the utmost contradiction to traditional female characters. By carnivalizing the narrative reality, Bulatovic degraded and inverted both the traditional and the revolutionary axiological system, and thus established new orders of things that, in relation to the basis from which they originate, represent extremely opposed semantic strings. The collective as the imperative of existential and moral survival in the war chronotope is broken down by the complete suppression of any form of collective interest and during that process individuality is placed in the center of the diegesis. Working on the theme of the war under the influence of the process of carnivalization, the author creates a powerful antiwar novel, whose wicked, to the core diabolical narrative reality, desemanticizeall the categories that Montenegrin culture on the one hand, and the communist ideology, on the other hand, have placed on the top of the moral scale.

Published: May 2021

The aim of this study is to evaluate the classification performances of land use/land cover (LULC) classification methods by comparing the results of pixel and object-based classification approaches on RapidEye satellite image. Pixel-based classification was carried out in ERDAS Imagine 10.4 using the Maximum Likelihood-supervised approach, whilst object-based classification was performed in e-Cognition Developer 64 using the nearest neighbour-supervised classification method. A LULC map of eight classes was created in both methods. While the accuracy for thematic LULC classes varied in both methods, the overall accuracy and kappa values of LULC maps for pixel and object-based classification methods were 58.39%-0.45 and 89.58%-0.86, respectively. Accuracy assessments and comparative results showed that object-based classification gives better results for thematic LULC classes as well as the overall accuracy of LULC maps. Even though pixel-based classification method was good at mapping many thematic classes, there were misclassifications between natural/semi-natural LULC classes. These results can be attributed to parameters set by users, such as the number of control points, etc. However, the capacity of object-based classification method to include auxiliary data (e.g. DEM, NDVI) increases the accuracy of LULC maps with high-resolution satellites.

Masyarakat Indonesia sangat gemar mengonsumsi sate, ayam/ bebek/ ikan bakar atau goreng karena sangat nikmat tetapi konsumen masih belum mengerti bahwa ada konsekuensi karsinogen heterocyclic aromatic amines (HAA) dan polycyclic aromatic hydrocarbons (PAH) yang berbahaya bagi kesehatan. Makalah ini bertujuan untuk mengupas tuntas HAA, PAH dan berbagai cara yang telah berhasil meminimalkan kadar mereka agar konsumen tetap dapat menikmati pangan tersebut dengan aman dan nyaman. Pemanasan daging adalah proses wajib untuk memastikan keamanan mikrobiologis, menghilangkan faktor antinutrisional, meningkatkan kecernaan dan bioavailabilitas nutrien, serta mengembangkan profil atribut warna, aroma dan citarasa daging yang kita inginkan. Namun, proses ini juga ternyata memunculkan karsinogen (pemicu kanker) HAA dan PAH yang berbahaya bagi kesehatan kita dalam jangka panjang. Pembentukkan HAA dan PAH sangat tergantung pada berbagai faktor seperti metode pemanasan, waktu pemanasan, suhu pemanasan, jenis daging, kadar lemak, kadar air, pH dan kadar kreatinin daging. Banyak penelitian menyimpulkan bahwa HAA dan PAH menyebabkan kanker pada manusia dan hewan. Hasil telaah pustaka ini memberikan informasi praktis yang bisa diterapkan oleh para produsen atau ibu rumah tangga untuk meminimalkan kadar HAA pada produk jadi, yakni memilih gula yang tepat untuk marinasi; penambahan antioksidan sintetis; penambahan antioksidan alami; dan praperlakuan menggunakan microwave.

Authors: Meimela Aida
Published: May 2021

One of the health issues listed in the Sustainable Development Goals (SDGs) is to end the tuberculosis epidemic in 2030. Indonesia is the country with the third-highest number of tuberculosis cases in the world after India and China in 2018. Aims of this study to model the number of tuberculosis cases in each province in Indonesia, depending on the characteristics of each region. Geographically Weighted Lasso (GWL) is a method used to overcome the local multicollinearity that appears in the Geographically Weighted Regression (GWR) model. By using this method, each region will have a different regression model according to its respective characteristics. There is local multicollinearity (VIF> 10) in each explanatory variable used. Banten, West Java, South Kalimantan, East Kalimantan, East Nusa Tenggara and Papua Province are provinces where all research variables affect the number of tuberculosis cases. The variable that has the most significant effect on the number of tuberculosis cases in each region in Indonesia is the number of health centers. Therefore, to end the number of tuberculosis cases, the government should increase the number of health centers and improve the health service.

Perdagangan merupakan bentuk kegiatan ekonomi yang memberikan pengaruh dalam meningkatkan perekonomian suatu daerah. Ketersediaan tempat, waktu, maupun barang tidak menjadi masalah dalam perdagangan, karena sentuhan teknologi menjadi salah satu solusinya. Teknologi dalam jual beli mempermudah penjual dan pembeli melakukan transaksi tanpa bertemu dan hanya berdasar pada asas iktikad baik. Mengenai permasalahan yang terjadi dalam proses penelitian beberapa responden mengaku masalah yang sering muncul berasal dari pihak pedagang. Karena pedagang sering telat dalam melakukan pembayaran. Masalah kecil yang sering timbul misalnya barangnya rusak atau tidak sesuai, kalau barangnya cacat, itu menjadi tanggung jawab penyuplai. Penggunaan perjanjian lisan dalam jual beli menjadi kebiasaan yang tidak bisa ditinggalkan oleh pedagang Pasar Klewer, walaupun mereka sadar bahwa posisi mereka lemah apabila terjadi permasalahan hukum dalam pelaksanaannya. Kesimpulan yang diperoleh bahwa perjanjian tidak tertulis yang dilakukan oleh Pedagang dengan Penyuplai barang di Pasar Klewer tetap sah dan mengikat kedua belah pihak, akan tetapi lemah dalam hal pembuktian apabila terjadi sengketa perdata. Di satu sisi lainnya kita mencoba meninjau dari penerapan asas iktikad baik dalam perjanjian lisan antara pedagang dengan penyuplai barang berdasarkan local wisdom.

OPTIMAL IMAGE SIGNALS PROCESSING ON THE NOISE BACKGROUND IN THE INFORMATION SYSTEM WITH ADAPTIVE ANTENNA ARRAY
Authors:   Military Academy (Odesa), Tkachuk O. V.
Published: May 2021

The method to restore image signals against the arbitrary intensity noise background in the information radio engineering system with adaptive antenna array has been developed. In order to use methods developed for processing one-dimensional signals for image recovery in the information system with adaptive antenna array, the transition from the two-dimensional array to vector representation is carried out. Mathematical model of narrowband signal formed at input of antenna array elements in space-time sense is obtained. Correlation matrices of image carrier signals, interference and noise are considered and features of adaptive processing of image signals coming from several sources are observed. An expression was found for the likelihood function if the incoming vector process is a multivariate stationary Gaussian process with a non-zero mean. According to the maximum likelihood criterion, the expression for the system of optimal independent parametric weight vectors necessary for image signals restoring against the arbitrary intensity noise background coming from several independent sources in the information system with adaptive antenna array is obtained. In accordance to this system, a signal processing algorithm is built in the adaptive processor of N-dimensional adaptive antenna array. A simulation model of image signal restores coming from one source in the information system with adaptive antenna array against the arbitrary intensity noise background coming from several independent sources is built. It is shown that the use of weight coefficients calculated on the basis of the correlation matrix of observations, due to its properties, does not allow dividing the set of correlated image signals. The direction of further development of the obtained results in the class of invariant methods is determined.

Investigation of the Ceiling Fixtures Design Evolution and LED Light Bar Alternative Concept Design Formation
Authors: Lobanov Yevhenii , Petchenko Glib
Published: May 2021

The purpose of the work is to study the development of concepts and technologies for the manufacture of ceiling fixtures to light the interior of buildings – office, public and administrative ones, etc. It is known that fluorescent lamps have long been used for interior lighting. Massive diffusers made of matte polycarbonate sheets were used to smooth the light intensity curve of such luminaires and bring it to the cosine light distribution. Due to the matte coating of the diffuser, the luminous part of the light fixtures acquired, with a fairly good approximation, the properties of an equally bright surface. Such surfaces are known to have a cosine light distribution and are very convenient for lighting. In the early 2000s, the problem of energy saving worsened, which led to a significant reduction in the number of luminaires of this type. These changes have also affected the approaches to the design of indoor light fixtures. The major difference of the new modifications of fluorescent fixtures is the absence of a matte reflector, which is very uneconomical in terms of energy saving, since it significantly decreased the luminous flux. The refusal to use the diffuser led to the emergence of fluorescent fixtures with a specular reflection system and shutters, which limited the dazzling effect of such lamps. However, with the parallel development of LED technology, the concept of choosing a light source in indoor lighting fixtures began tochange. In grille fixtures, LEDs were gradually replacing fluorescent ones. Nowadays, manufacturers' websites offer a fairly wide selection of LED fixtures. They differ in the price, quality of LEDs used, design and technological solutions. Recently, the volume of production and range of LED light bars has been increasing. The article presents an attempt to consider which fixtures offered on the modern market are the most balanced in terms of engineering solution in the context of lighting, operational, pricing, technological and certification characteristics. Based on the analysis of fixtures of different types and modifications, the authors concluded that the most optimal engineering solution is ceiling LED light bars and developed a method of their design and certification.
Cyborg or Goddes?
Authors: Graham Elaine
Published: May 2021

This article works on the premise that critical posthumanism both exposes and calls into question the criteria by which Western modernity has defined the boundaries between nature, humanity, and technology. Yet the religious, cultural and epistemological developments of what is known as the ‘postsecular’ may signal a further blurring of another set of distinctions characteristic of modernity: between sacred and secular, belief and non-belief. Using Donna Haraway’s famous assertion that she would ‘rather be a cyborg than a goddess’, I consider whether critical posthumanism’s valorisation of cyborg identities is also capable of negotiating this ‘final frontier’ between immanence and transcendence, secular and sacred, humanity and divinity. In essence: is there space for a religious dimension to visions of the posthuman?
Interleukin 4 promotes phagocytosis of murine leukemia cells counteracted by CD47 upregulation
Authors: Peña-Martínez Pablo , Ramakrishnan Ramprasad , Högberg Carl , Jansson Caroline , Nord David Gisselsson , Järås Marcus
Published: May 2021

Cytokines are key regulators of tumor immune surveillance by controlling immune cell activity. Here, we investigated whether interleukin 4 (IL4) has antileukemic activity via immune-mediated mechanisms in an in vivo murine model of acute myeloid leukemia driven by the MLL–AF9 fusion gene. Although IL4 strongly inhibited leukemia development in immunocompetent mice, the effect was diminished in immune-deficient recipient mice, demonstrating that the antileukemic effect of IL4 in vivo is dependent on the host immune system. Using flow cytometric analysis and immunohistochemistry, we revealed that the antileukemic effect of IL4 coincided with an expansion of F4/80+ macrophages in the bone marrow and spleen. To elucidate whether this macrophage expansion was responsible for the antileukemic effect, we depleted macrophages in vivo with clodronate liposomes. Macrophage depletion eliminated the antileukemic effect of IL4, showing that macrophages mediated the IL4-induced killing of leukemia cells. In addition, IL4 enhanced murine macrophage-mediated phagocytosis of leukemia cells in vitro. Global transcriptomic analysis of macrophages revealed an enrichment of signatures associated with alternatively activated macrophages and increased phagocytosis upon IL4 stimulation. Notably, IL4 concurrently induced Stat6-dependent upregulation of CD47 on leukemia cells, which suppressed macrophage activity. Consistent with this finding, combining CD47 blockade with IL4 stimulation enhanced macrophage-mediated phagocytosis of leukemia cells. Thus, IL4 has two counteracting roles in regulating phagocytosis in mice; enhancing macrophage-mediated killing of leukemia cells, but also inducing CD47 expression that protects target cells from excessive phagocytosis. Taken together, our data suggest that combined strategies that activate macrophages and block CD47 have therapeutic potential in acute myeloid leukemia.

Background: To foster family planning activities by postpartum IUCD insertion, side effects and complications of PPIUCD insertion need to be characterized. The study was conducted to find out the outcomes of postpartum intrauterine contraceptive device insertion among women attending a tertiary level hospital.

Methods: A cross sectional study was conducted among 130 women. Data were collected by face-to-face interview and reviewing medical records with semi- structured questionnaire and checklist. The subjects were purposively selected following specific selection criteria and maintaining ethical issues. The study was conducted during the period from October 2016- March 2017 in a tertiary hospital: Shaheed Suhrawardy Medical College Hospital (ShSMCH), Dhaka.

Results: The study revealed that majority (53.1%) of women were 25-30 years and the mean (±SD) age was 26.40±4.273 years. Around 26.2% had secondary education and most of them i.e. 60.8% were housewife. Study revealed that average monthly family income was Tk. 20815.38 ± 9097.904. Majority (90%) of women choose PPIUD because it is convenient. Most of the respondents were inserted immediately after delivery within 10 minutes. Intracaesarean and manual insertion of PPIUCD was practiced in majority i.e. 79(60.8%) of the respondents. The study revealed that three fourth of the respondents had no side effect while common side effects of PPIUCD included vaginal discharge (12.3%), thread coming out (14.6%), missing thread (13.8%), lower abdominal pain (16.2%), expulsion (6.2%) and coital discomfort (10.8%). Only 18.5% respondents had abnormal uterine bleeding and 6.2% had PID. The results show expulsion rate was more in vaginal route (11.8%) than intra-caesarean route (2.5%) and this difference was statistically significant (p<0.05). All complications like abnormal uterine bleeding (15.7%) and PID (20.3%) were seen more in vaginal insertions as compared to insertion during caesarean section and was statistically significant (p<0.05).

Conclusion: To reduce the unwanted pregnancy in postpartum period and maternal and child mortality and morbidity, PPIUCD insertion along its continuation by overcoming side effects and complications is an earnest need in a densely populated country like Bangladesh.

Published: May 2021

Background: The incidence of gestational trophoblastic disease varies dramatically in different regions of the world. While there are some geographical and racial variations, perhaps a higher incidence in Africa and Asia. The high incidence of molar pregnancy in some populations have been attributed to nutritional and socioeconomic factors. Some maternal biological factors also associated with molar pregnancy. This study aims to explore the various maternal risk factors associated with molar pregnancy.

Methods: This case control study was carried out among 50 molar and 100 non-molar pregnant mothers admitted at in patient department of obstetrics and gynecology, Rajshahi Medical College Hospital from January to December 2011. The patients of molar pregnancies were selected on the basis of clinically diagnosed confirmed by ultrasonogram and histopathological examination. Controls group were selected as pregnant women of 1st & 2nd trimester. With the ethical approval from the institutional review board (IRB), patients were selected after taking their written consent. A structured questionnaire and a check list were designed with considering all the variables of interest.

Results: Out of 50 cases 48% belongs to the age group below 20 years, 17% belongs to the age group above 34years. 88% of the control groups are belongs to the age group 20-34 years. Out of 50 cases 4% had history of prior molar pregnancy, none of the control groups had prior history of mole. 46% of molar cases belongs to the blood group A, 82% in case group and 86% of control group were hormonal contraceptive users. Among the socio-demographic risk factors occupation, education, socioeconomic condition, nutritional status of the case and control group were included.

Conclusion: Molar pregnancy largely remains as etiologic dilemma. No pregnancy is immune to develop as hydatidiform mole. As the risk factors for the disease are unclear, an attempt has been made to identify some risk factors of molar pregnancy to compare them with normal pregnancy to find out any modifiable factors.

Computational investigations is reported on a flat plate subjected to combined impingement and film cooling. Conjugate heat transfer and 3-D steady RANS approach with the k-ω SST turbulence model were used for analysis of the impingement and film cooling plates. The flow dynamic features of impinging jets and the coolant-mainstream interaction in presence of heat shield are described. The discharge coefficients are presented at blowing ratio M = 0.2 to 0.8 and Reynolds number Re 9300 to 75000 respectively. A comparison between the conventional heat shield and ultra-high impingement distance heat shield shows that the discharge coefficients values for the new heat shield are higher. The value of overall cooling effectiveness for the new heat shield is lower than the conventional structure at low blowing ratio, but at high blowing ratio, the values of overall cooling effectiveness for both the heat shields are almost equal. As the blowing ratio is increased from 0.2 to 0.8, the overall effectiveness values show an increasing trend for both the heat shields.

As technology advances, rotating machinery is becoming smaller and operating at higher rotational speeds, with increased pressure and heat concentration. This combination of factors increases structural stresses, while increasing the risk of temperature sensitive components over heating. To properly protect these components, such as bearings and seals, and reduce structural stresses, it is necessary to have accurately designed thermal management systems with well-understood heat transfer characteristics. Currently available heat transfer correlations operating within high Taylor number (above1×1010) flow regimes are lacking. In this work, the design of a high Taylor number flow experimental test rig is presented. A non-invasive methodology, used to capture the instantaneous heat flux of the rotating body, is presented. A new correlation for Taylor numbers between 0.0and 9.0×108 with airis provided using the effective Reynolds number. Capability of the test rig and methodology enables the use of high density fluids, such as supercritical carbon dioxide, providing opportunity to develop correlations up to 1×1012.A unique approach is presented, using the Monte-Carlo method for evaluating the uncertainties in the calculated values. Data of a single testis presented for a Taylor number of 8.9±1.6×107 and an effective Reynolds number of 3.3±0.2×104. This operating condition corresponded to a measured heat transfer coefficient of 3.16±0.9×102W/m2K and Nusselt number of 8.9±1.6×101. This level of detailed uncertainty analysis for heat transfer coefficient measurements is not present in existing literature. This paper represents the first comprehensive portrayal of uncertainty propagation in heat transfer coefficient measurements for Taylor-Couette-Poiseuille (T-C-P) flow heat transfer experiments.

Ceramide is a bioactive signaling lipid involved in the pathogenesis of numerous diseases. It also plays an important role in ischemia reperfusion (IR) injury via activation of inflammatory/oxidative stress-stimulated signaling pathways, resulting in tissue damage. Acid ceramidase is a lipid hydrolase that modulates the levels of ceramide, and as such has a potential therapeutic role in many human diseases where ceramide has been implicated. Here we investigated the therapeutic potential of recombinant acid ceramidase in a murine model of hepatic IR injury. Serum ALT, AST, and LDH activities, as well as oxidative stress (MDA) and inflammatory (MCP-1) markers, were increased in mice subjected to IR compared to a sham group. In contrast, these elevations were significantly lower in an IR group pretreated with a single injection of acid ceramidase. Histological examination by two different assessment criteria also revealed that acid ceramidase pretreatment alleviated IR-induced hepatocyte damage, including reduced evidence of cell death and necrosis. In addition, elevated ceramide and sphingosine levels were observed in the IR group compared to sham, and were markedly reduced when pretreated with acid ceramidase. In contrast, the levels of the protective signaling lipid, sphingosine-1-phosphate (S1P), were reduced following IR and elevated in response to acid ceramidase pretreatment. These changes in sphingolipid levels could be correlated with changes in the activities of several sphingolipid-metabolizing enzymes. Overall, these results indicated that sphingolipid changes were an important pathologic component of hepatic IR injury, and that acid ceramidase administration ameliorated these lipid changes and other downstream pathologic changes.
