Published: February 2023

Mrk 501 is one of the most prominent TeV-emitting blazars and belongs to the class of high synchrotron peaked (HSP) blazars. The Doppler factors derived from the jet kinematics are much too low to provide sufficient beaming for the detected high-energy emission (the so-called Lorentz factor crisis). This BL Lac object is also a prime example of a misaligned AGN with an approximately 90∘ difference in orientation between the inner parsec-scale jet and the kpc-scale jet structure. We have performed a detailed analysis of the pc-scale jet kinematics, based on 23 years of VLBA observations (at 15 GHz) and find, in addition to robustly consolidating the already claimed stationary jet features and a hinted absence of component ejections, a significant drift of the outer nuclear jet. The two outermost jet features move with somewhat higher but still subluminal speeds. Albeit, they move orthogonally to the inner jet, which itself does not partake in the drifting motion. The effect of this intriguing kinematics is that the jet appears strongly curved at first (1995) but then appears to straighten out (2018). To our knowledge, this is the first time that the orthogonal swing of just the outer part of a nuclear jet has been observed. We discuss the possible physical nature of this turning maneuver. In addition, we report evidence for jet emission, which most likely originates in a spine–sheath structure.

During the Zika virus (ZIKV) outbreak and after evidence of its sexual transmission was obtained, concerns arose about the impact of the adverse effects of ZIKV infection on human fertility. In this study, we evaluated the clinical-laboratory aspects and testicular histopathological patterns of pubertal squirrel monkeys (Saimiri collinsi) infected with ZIKV, analyzing the effects at different stages of infection. The susceptibility of S. collinsi to ZIKV infection was confirmed by laboratory tests, which detected viremia (mean 1.63 × 106 RNA copies/µL) and IgM antibody induction. Reduced fecal testosterone levels, severe testicular atrophy and prolonged orchitis were observed throughout the experiment by ultrasound. At 21 dpi, testicular damage associated with ZIKV was confirmed by histopathological and immunohistochemical (IHC) analyses. Tubular retraction, the degeneration and necrosis of somatic and germ cells in the seminiferous tubules, the proliferation of interstitial cells and an inflammatory infiltrate were observed. ZIKV antigen was identified in the same cells where tissue injuries were observed. In conclusion, squirrel monkeys were found to be susceptible to the Asian variant of ZIKV, and this model enabled the identification of multifocal lesions in the seminiferous tubules of the infected group evaluated. These findings may suggest an impact of ZIKV infection on male fertility.

Childhood vaccination is crucial to protect young children from harmful infectious diseases. This study aimed to investigate the recent childhood immunization rate of recommended and additional vaccinations and identify the factors affecting the vaccination uptake of young children in Hong Kong. The self-administrated questionnaires were distributed to parents of toddlers aged 2 to 5. They were asked to provide information on (1) socioeconomic demographic factors; (2) experiences during pregnancy; and (3) the medical history of the toddler. A total of 1799 responses were collected. Children were more likely to be fully vaccinated when they were at a younger age (aOR = 0.61, 95% CI: 0.48–0.78, p < 0.001), the first child in the family (aOR second-born = 0.62, 95% CI: 0.48–0.81, p < 0.001; aOR third-born = 0.33, 95% CI: 0.19–0.55, p < 0.001), had a higher household income (aOR HKD 15,000–HKD 29,999 = 1.80, 95% CI: 1.27–2.55, p = 0.001; aOR ≥ HKD 30,000 = 3.42, 95% CI: 2.39–4.90, p < 0.001; compared with <HKD 15,000), or with mothers in older age groups (aOR 35–39 years old = 2.45, 95% CI = 1.22–4.93, p = 0.012; aOR ≥ 40 = 2.90, 95% CI = 1.24–6.77, p = 0.014; compared with ≤ age 24). The uptake of any additional vaccination was 71%. Children who were older (aOR = 1.32, 95% CI: 1.02–1.70, p = 0.036), the first child in the family (aOR second-born = 0.74, 95% CI: 0.56–0.99, p = 0.043; aOR third-born = 0.55, 95% CI: 0.32–0.96, p = 0.034), with higher household income (aOR ≥ HKD 30,000 = 1.61, 95% CI: 1.10–2.37, p = 0.016), were exposed to second-hand smoke from the father (aOR: 1.49, 95% CI: 1.08–2.07, p = 0.016), experienced hospitalization (twice or more—aOR: 1.44, 95% CI: 1.04–1.99, p = 0.027), or were fully vaccinated (aOR: 2.76, 95% CI: 2.12–3.60, p < 0.001) were associated with a higher chance of taking an additional vaccine. To encourage the vaccination rate, more attention should be given to families with more children, low-income families, and younger mothers.

Published: February 2023

Immunogenicity data on the mRNA SARS-CoV-2 vaccine booster after completing a primary series vaccination, other than the mRNA vaccine, in patients with autoimmune rheumatic diseases (ARDs) is scarce. In this study, we reported the humoral immunogenicity of an mRNA booster 90–180 days after completing heterologous CoronaVac/ChAdOx1 nCoV-19 (n = 19) or homologous ChAdOx1 nCoV-19 (n = 14) vaccination by measuring the anti-SARS-CoV-2 receptor binding domain (RBD) IgG levels at one and three months after mRNA booster vaccination. This study included 33 patients with ARDs [78.8% women; mean (SD) age: 42.9 (10.6) years]. Most patients received prednisolone (75.8%, mean [IQR] daily dose: 7.5 [5, 7.5] mg) and azathioprine (45.5%). The seropositivity rates were 100% and 92.9% in CoronaVac/ChAdOx1 and ChAdOx1/ChAdOx1, respectively. The median (IQR) anti-RBD IgG level was lower in the ChAdOx1/ChAdOx1 group than in the CoronaVac/ChAdOx1 group (1867.8 [591.6, 2548.6] vs. 3735.8 [2347.9, 5014.0] BAU/mL, p = 0.061). A similar trend was significant in the third month [597.8 (735.5) vs. 1609.9 (828.4) BAU/mL, p = 0.003]. Minor disease flare-ups occurred in 18.2% of the patients. Our findings demonstrated satisfactory humoral immunogenicity of mRNA vaccine boosters after a primary series, with vaccine strategies other than the mRNA platform. Notably, the vaccine-induced immunity was lower in the ChAdOx1/ChAdOx1 primary series.

Prior to the identification of low pathogenic avian influenza H9N2 viruses belonging to the Y280 lineage in 2020, Y439 lineage viruses had been circulating in the Republic of Korea since 1996. Here, we developed a whole inactivated vaccine (vac564) by multiple passage of Y439 lineage viruses and then evaluated immunogenicity and protective efficacy in specific-pathogen-free chickens. We found that LBM564 could be produced at high yield in eggs (108.4EID50/0.1 mL; 1024 hemagglutinin units) and was immunogenic (8.0 ± 1.2 log2) in chickens. The vaccine showed 100% inhibition of virus in the cecal tonsil with no viral shedding detected in either oropharyngeal or cloacal swabs after challenge with homologous virus. However, it did not induce effective protection against challenge with heterologous virus. An imported commercial G1 lineage vaccine inhibited viral replication against Y280 and Y439 lineage viruses in major tissues, although viral shedding in oropharyngeal and cloacal swabs was observed up until 5 dpi after exposure to both challenge viruses. These results suggest that a single vaccination with vac564 could elicit immune responses, showing it to be capable of protecting chickens against the Y439 lineage virus. Thus, our results suggest the need to prepare suitable vaccines for use against newly emerging and re-emerging H9N2 viruses.

As parasitoses gastrintestinais são as infecções estabelecidas no tubo gastrintestinal, e podem ser causadas por parasitos como os helmintos e coccídeos. O diagnóstico desses parasitas pode ser realizado de diversas maneiras e técnicas, sendo a mais conhecida, prática e rápida a técnica popularmente conhecida como método OPG, que determina o número de ovos do parasita por grama de fezes para calcular a carga parasitária do animal. O OPG apesar de ser a técnica mais utilizada, apresenta muita variabilidade nos resultados e diversas modificações foram descritas a fim de melhorar a eficiência da técnica. Por isso, o objetivo deste trabalho foi comparar modificações das técnicas que resultam no número de OPG para determinar se alguma das modificações se equipara ao resultado da técnica padrão. Para seu desenvolvimento foi realizada a coleta de um pool de amostras de animais da espécie ovino, naturalmente infectados por helmintos; as amostras foram processadas por quatro modificações da técnica padrão, conhecido como o “Método de Gordon e Whitilock modificado”, utilizando-se a câmara McMaster, a fim de tentar estimar a carga parasitária dos animais. Para cada técnica foram feitas cinco repetições utilizando a mesma amostra fecal homogeneizada, em todas as repetições e em todas as técnicas. Concluímos que a técnica padrão mostrou ser a técnica mais eficiente e viável, visto que os seus resultados diferiram estatisticamente das demais técnicas mesmo que algumas modificações produzam uma menor quantidade de resíduo ou que necessitem uma menor quantidade de amostra.

Book Review: Economic Episodes in American History, 2nd ed.
Authors: Newman Patrick
Published: February 2023

The second edition of _Economic Episodes in American History_ by Mark Schug, William Wood, Tawni Hunt Ferrarini, and M. Scott Niederjohn is a welcome response to the changes in how the beleaguered subject has been taught in high schools over the past eleven years (the first edition came out in 2011). For Schug et al.’s work provides the cure for the current pedagogical dispensation: learning American history is important because it is a way students can understand what economists call the economic way of thinking, capitalism and industrial development were (and still are) responsible for an unprecedented rise in living standards, and capitalism especially improved the well-being of women and minorities.

Authors: FAN Rong , LI Wei , WU Zhiming , BU Bin
Published: February 2023

In order to reduce the drift loss of small droplets sprayed at low altitudes and low volume, a two-channel two-phase electric centrifugal nozzle was designed. The three-dimensional full-size numerical simulation of the flow field in the nozzle was carried out using Fluent software, and the radial distribution characteristics and axial variation of the flow field were studied. The relationships between the motor voltage and the atomizing disc's speed, between the nozzle's inlet pressure and its flow rate were determined. The variations of the droplet size and the droplet spectrum width with the atomizing disc and flow rate were revealed. The results showed that the rotation speed and flow rate were the important factors affecting the droplet's middle diameter and spectrum width. When the rotation speed of atomizing disc was 4000 r/min, the droplet spectrum width exhibited the narrowest, and the middle diameter of the droplet volume was 231.9 μm. The droplet coverage density was higher, meeting the requirements of low-volume aviation spraying control. This study provides a theoretical basis for optimizing nozzle configuration and developing variable spray devices.

Published: February 2023

The use of energies from renewable sources, as an alternative to those obtained from fossil fuels, represents a sustained concern in the world scientific environment, this action being a particularly important objective at present, especially in the context of increasingly acute manifestations of the effects of climate change. The recovery and use of thermal energy developed in the composting process of biodegradable and solar waste is a current concern of the research environment in the field. In this paper we want to present some research on the recovery of thermal energy from the two renewable energy sources mentioned in order to use thermal energy for the production of the agent that can be used in the current activity of individual agricultural and livestock farms as well as in households, for the preparation of domestic hot water and heating of living spaces, greenhouses, and solariums. The paper presents the current state of research, some theoretical considerations regarding the thermodynamic phenomena that occur in the thermal energy recovery process, a modulated system for the recovery of thermal energy from the composting process and solar energy, experimentation in real operating conditions, the results and their interpretation and related conclusions.

Published: February 2023

In this paper, the vibration characteristics of the 1ST-460 vibration subsoiler was analyzed. In order to solve the problem of vibration imbalance caused by the vibration component under the action of multiple groups of vibration shovels, the optimal combination mode of the vibration component under the interaction of multiple groups of shovels was obtained. Piezoelectric accelerometers are fixed symmetrically on the frame of the subsoiler to measure the vibration at different positions. TST5910 dynamic signal test and analysis system is used to collect and process the acceleration data. Non-load tests were carried out with different initial eccentric phase angle combination. Results showed that the combination of [0°, 180°, 180°, 0°] (symmetrically up and down staggered vibration) for the eccentric vibration component of four shovels is the optimal initial phase combination, which can lead to the minimum adverse vibration on the frame. Further tests were conducted under different vibrating frequency and amplitude/eccentric with optimal phase combination. The results showed that, when amplitude/eccentricity ratio was 2.0 and 2.5, frequency of vibration was 6.7 and 8.3 Hz, the required traction force of the subsoiler was stable and significantly reduced, which can improve the soil loosening performance and reduce the harmful vibration on the tractor.
A "Classical" Response to Contemporary Issues: Examples of Informal Mosque Production in Beykoz, Istanbul

Published: February 2023

Through examples from Beykoz, this study questions and investigates informality as a substantial phenomenon in the architectural and spatial formation of mosque buildings in Istanbul's informally developed neighbourhoods. The goal is to provide a new theoretical perspective on this legitimate yet illegal/informal form of socio-spatial practice in relation to the specific dynamics of Istanbul's informal urbanity and architectural production. As for methodology, following a theoretical and historical survey on the informal urbanity and procedures of mosque production in Turkey, the architectural and spatial features of three mosque complexes are analysed, evaluated, and discussed. The data was obtained through site surveys and interviews with the primary actors involved in their constructions. This data was processed into scaled drawings for a comparative analysis of their formal and spatial configurations. The study concentrated on gathering first-hand information from the producers of these mosques and the buildings themselves. The results showed that the builders, who were also the future users, followed an imprecise classical mosque scheme during their building processes. Their participatory and spontaneous construction processes also brought innovation in the spatial and formal organization, employing improvisation. The architectural and spatial aspects of these building complexes also presented considerable problems. Finally, the research aims to contribute new studies for developing new strategies and legal frames, engaging the will and the energy of the users to shape their social and physical environments in the urban context.

Published: February 2023

While the efforts to ensure the ecological balance for a sustainable and livable future have gained momentum in recent years, sustainable materials have become more needed in this context. Sustainable materials can be summarized as materials that consume less energy and do not harm the environment, nature, and human health, from the process of obtaining their raw materials to the processing stages, their use, maintenance, and repair, and the environmental conditions they are in during waste generation. In addition, they are local materials that respond to the culture they are in, are open to change, recyclable, non-toxic, and non-poisonous. Sustainable urban furniture can contribute to the future by minimizing environmental problems. Within the scope of this study, urban furniture such as seating elements, trash bins, lighting elements, pavement materials, playgrounds, and pergolas in the newly built or revised green areas in the center of Rize in the last five years, in the context of sustainable materials; Durability / Easy maintenance, Performance, Functionality, Space Relation, Economy, Recyclability, Aesthetics, and Ecological Materials were examined by considering criteria. By evaluating the results, evaluations were made on the materials used in urban furniture to create ecological and sustainable environments.
Fabrication of metal/oxide/fluorographene/oxide/silicon capacitors and their charge trapping properties
Authors: Kawashima Rino , Nohira Hiroshi , Ishikawa Ryousuke , Mitani Yuichiro
Published: February 2023

Graphene is well-known as a material with extremely high carrier mobility, although its electrical properties can be changed into those of a highly insulating thin film by a fluorination treatment (fluorographene). Taking advantage of this property, a flexible nonvolatile memory using fluorographene as a charge trapping layer has been proposed. However, the mechanism of charge trapping on fluorographene is not yet fully understood. In this paper, we fabricated fluorographene and analyzed it by X-ray photoelectron spectroscopy and Raman spectroscopy. Furthermore, metal–insulator–semiconductor (MIS) capacitors inserted with fluorographene were fabricated and evaluated electrically. As a result, a large flat-band voltage shift was observed even though the fluorine concentration (C–F bonding ratio) was saturated at around 14%. Furthermore, the charge centroid of the MIS capacitor with fluorographene coincides with the location of the fluorographene. These results indicate that fluorographene can capture injected charges and is a candidate for use in nonvolatile memory with two-dimensional materials.

The heteroepitaxial growth of In2O3 on a (0001) α-Al2O3 substrate was carried out using the mist chemical vapor deposition method. The concentrations of In2O3 powder in the source precursor solution varied between 0.025 and 0.250 mol l−1. An increase in the growth rate was observed with the increasing In2O3 powder concentration, and the highest growth rate of 4.2 μm h−1 was obtained at a powder concentration of 0.150 mol l−1. An improvement in the electrical properties was eventually observed, i.e. the lowest carrier concentration of 3.1 × 1017 cm−3 and the highest Hall mobility of 241 cm2 V−1 s−1 at room temperature were obtained at a powder concentration of 0.150 mol l−1. The temperature-dependent Hall effect measurement for the sample showed pronounced carrier freeze-out in a temperature range of 300–30 K, indicating that the α-In2O3 film had near-non-degenerate conductivity.

Electronic structures and molecular dynamics of gadolinium-doped FAPbI3 perovskite crystals
Authors: Suzuki Atsushi , Oku Takeo
Published: February 2023

The additive effect of a gadolinium ion into a formamidinium lead iodide (FAPbI3) perovskite crystal on electronic structures and molecular dynamics was investigated for improving photovoltaic performance with stability. The electronic structures, band structure, partial density of state, and molecular dynamics were determined by first-principles calculation. The band distribution and charge transfer between the 5d orbital of the gadolinium atom, the 5p orbital of the iodine atom, and the 6p orbital of the lead atom promoted the carrier generation and diffusion related to short-circuit current density. The enthalpy and kinetic energy prompted stabilization of the gadolinium-doped crystal with a slight distortion of coordination structure, as compared with the decomposition of the FAPbI3 crystal. Diffusion coefficients of iodine and lead ions in the FAPbI3 crystal with defect were increased, predicting decomposition. The gadolinium-doped FAPbI3 perovskite crystal has great potential for applications in photovoltaic devices by improving photovoltaic performance.

Published: February 2023

Her research focuses on American literature, with a particular emphasis on 19th- and 20th- century American travel literature. Her doctoral dissertation, entitled The Cruise of the Vanadis: in the footsteps of Edith Wharton, explores Edith Wharton’s 1888 travel narrative, The Cruise of the Vanadis. Wharton never thought fit to submit it to her publishers and, as a consequence, it lay in her drawers unpublished until it was rediscovered in 1992. This narrative is invaluable as it gives a clear picture of the underlying influences that nourished the vision of the future novelist.

Proiect investițional de tip model pentru sectorul agrar – Producerea florilor de crizanteme
Authors: Bajura Tudor , Turetchi Viorel
Published: February 2023

Actualmente, în Republica Moldova piața de desfacere a florilor, în special a crizantemelor, este într-o continue dezvoltare, fiind remarcată mai des în centrele raionale și orașele mari precum or. Chișinău și Bălți. Totodată ea este puternic influențată de caracterul sezonier și de importurile din exterior. Preponderent, cota florilor de crizanteme se află la un nivel ridicat în perioada lunilor decembrie – aprilie, iar pe parcursul anului fiind importate în mediu 1,7 milioane flori, 27 cedând dor importului de trandafiri care reprezintă în jur de 2,6 milioane unități. Principalele țări de unde sunt efectuate importurile către țara noastră sunt Olanda și Ecuador. Din punct de vedere a producției de crizanteme autohtone, industria abia face primii pași, producerea fiind concentrată în sectoarele casnice și pe suprafețe mici. Acestea au mai mult un caracter sezonier, cantitatea de bază fiind recoltată și comercializată toamna (perioada biologică de înflorire a crizantemelor în condițiile Republicii Moldova), cedând cu mult atât după valoare, cât și calitate florilor importate. Doar o parte neînsemnată de producători cultivă crizantemele în teren protejat, dar și aceștia finalizează procesul de producere în luna decembrie. Cu toate acestea, actualmente, condițiile meteorologice locale, posibilitățile tehnice și materiale ar permite cultivarea crizantemelor și producerea florilor pe întreaga perioadă a anului, fapt ce ar suplini deficitul de flori în perioada rece a anului. Dar pentru ca această activitate să devină profitabilă iar producția obținută să fie concurabilă cu cea de import este necesar ca producătorul autohton să implementeze tehnologiile noi de producere, să cultive soiurile de crizantemă care au o cerere ridicată pe piața moldovenească. În contextul dat, proiectul - model investițional are ca scop familiarizarea potențialilor producători cu principalele elemente de producere a acestei culturi, aspectele financiare, planificarea și gestionarea resurselor financiare, metodele de evaluare a proiectului respectiv, și, nu în ultimul rând, riscurile care pot apărea în procesul investițional.

Authors: E Akshatha , KB Ranjith , M A Balakrishna
Published: February 2023

Introduction: TNBC is associated with high mortality, morbidity and low survival rates. This study is
aimed to study difference in pathological characteristics, disease free survival and recurrence between
TNBC and Non-TNBC. Materials and Methods: Total 208 patients, who are diagnosed cases of breast carcinoma visiting our
out patient department between August 2020 and July 2022 were enrolled. Demographic details, details during the
presentation, pathological characterstics including the HPE, grade and receptor status, modality of treatment were taken.
Enrolled patients were followed up. At the end of the study period, 2 year disease free survival, overall survival, recurrence of
malignancy were noted. 102 patients who lost followup, status unknown or who has not completed a period of 2 years after
diagnosis of Breast carcinoma were excluded. 106 patients were nalised, details were entered in excel sheet. Patients were
divided into TNBC and Non-TNBC group and compared. Results: Prevalence of TNBC in our study was 22.6. Tumor size is more
at presentation in TNBC compared to Non TNBC. All patients with TNBC had positive nodes during presentation (100%Vs78%).
Presence of metastasis at the time of diagnosis is more in TNBC group(20.8%Vs 8.5%). Both groups has Intraductal Carcinoma
as the predominant variant. Most of the TNBC had poorly differentiated grade tumors when compared to Non-TNBC. TNBC has
more local(38.8% Vs 18.7%) and metastatic(22.22% Vs 4%) recurrences. 2 year Diseases free survival was more in Non-TNBC
group(77.33% Vs 38.88%). Conclusions: TNBC has overall lesser disease survival period, more local and metastatic
recurrences. Stage at diagnosis in TNBC is more advanced. Hence TNBC has got poor prognosis and high mortality. Early
diagnosis and treatment is the key in reducing the mortality and better prognosis.

Published: February 2023

Ruminant welfare post-surgery could be improved by employing a procedural technique that causes minimal surgical stress. A total of twenty-four (n = 24) Kano Brown goats (KBGs) aged 1–2 years, weighing an average of 15.52 kg, were recruited for the study. Rumen skin clamp fixation (RSCF) and a stay suture rumenotomy (SSR) in lateral recumbency while standing restraint rumenotomy was aided by a locally fabricated mobile small ruminant surgical chute (MSRSC) were performed in groups A, B, and D, respectively, as control group C had no surgery. Six goats were allocated to each group such that each group had 3 males and females that were positive for rumen foreign body impaction (RFBI), except goats in group C that were free of RFBI. Pre- and post-rumenotomy values of vital parameters did not differ significantly (P > 0.05). The group A serum IL-6 concentrations at 72 hours post-rumenotomy (61.21 ± 44.52 ng/L) were significantly higher (P < 0.05) than those in group D (15.24 ± 3.09 ng/L) among the female KBGs. The concentrations of IL-6 at week 1 post-rumenotomy in group A were significantly higher (65.05 ± 31.11 ng/L) than in groups B (15.86 ± 0.29), D (18.75 ± 5.81) and C (14.86 ± 0.79 ng/L). The lack of significant changes in the mean values of rectal temperature, respiratory rate, and heart rate implies that the standing rumenotomy utilizing the MSRSC did not vary in surgical stress severity from the conventional approaches; RSCF and SSR, done in lateral recumbency. The IL-6 in group D was lower when compared to the values in group A females at 72 hours and at week 1 for the male KBGs, suggesting profound surgical stress among females and males in groups A and B over group D. Standing restraints cause less surgical stress than lateral recumbency restraints, making it a better procedural approach for rumenotomy in goats.
Evaluation of Aqueous -Methanol Stem Bark Extract of Andira inermis for Peptic Ulcer-Protective Activity in Rats

Published: February 2023

Peptic ulcer disease is one of the commonest gastrointestinal diseases in the world and several orthodox drugs have been employed for the treatment of this disease. Although effective, some of these drugs produce adverse effects with a great tendency for the disease to reoccur. Hence, the need for further screening of medicinal plants for potential antiulcer activity and as sources for antiulcer lead compounds. Andira inermis is one of the plants identified to be used traditionally in ulcer-related conditions. This research work was aimed at evaluating the peptic ulcer-protective effects of aqueous-methanol stem bark extract of A. inermis in rats with acetylsalicylic acid and cold stress-induced ulceration. Adult Wistar rats were grouped into 5 of five rats each. Rats in Group A were administered normal saline (30 ml/kg i.p) to serve as the negative control. Rats in groups B, C and D were pretreated with the graded doses of the extract (100, 200 and 400 mg/kg i.p). Rats in group E were treated with Cimetidine (100 mg/kg i.p) to serve as the positive control group. Thirty minutes post-treatment, ulceration was induced with acetylsalicylic acid (150 mg/kg p.o) and all the rats were subjected to cold restrain stress for a 4h period. The rats were then sacrificed humanely and their stomachs were excised for gross examination and scoring of ulcer indices. The mean ulcer indices, percentage severity of ulceration and percentage ulcer protection were determined using corresponding calculations. The results revealed that acetylsalicylic acid combined with cold stress caused mostly marked congestion, gross erosions and deep ulcers with ecchymotic and petechial hemorrhages on the gastric mucosa of the rats treated with normal saline (30 ml/kg i.p.). The aqueous methanol stem bark extract of A. inermis significantly (p < 0.05) inhibited the formation of these lesions. The extract caused increased secretion of mucous on the gastric mucosa of rats and a dose-dependent reduction in ulcer indices. This was significant (p < 0.05) at the dose of 400 mg/kg i.p of the extract. The extract, at graded doses of 100, 200 and 400 mg/kg i.p produced percent ulcer protection of 60.0%, 73.3%, and 80.0% respectively. This was comparable to Cimetidine which showed a percent ulcer protection of 86.7%. This shows that the stem bark extract of Andira inermis possesses gastro-protective effects and has the potential to be developed as an agent for the treatment of peptic ulcers..

Published: February 2023

Foot and Mouth Disease is a contagious viral disease of cattle and sheep, causing ulceration of the hoofs and around the mouth. The role of small ruminants in FMD epidemiology is still poorly understood in Nigeria. The aim of the study is to determine the prevalence of Foot and Mouth Disease Virus (FMDV) antibodies in sheep and goats slaughtered in Karu abattoir. One hundred and twenty (120) sera each were collected from both sheep and goats and screened for FMDV antibodies using 3ABC ELISA. The result showed that 89 (74.2) of the sheep sera screened were positive for FMDV antibodies whereas 103 (85.8) of the goat sera were positive. It was more prevalent in goats. The finding indicates a characteristic maintenance host nature for FMD virus in small ruminants without apparent clinical signs. This study suggested an on-going infection in small ruminant co-herding with cattle as a risk factor. This risk factor may enhance FMD transmission associated with increased movement of infected live animals from endemic states to markets and abattoirs following livestock trade activities. FMD is a Transboundary Animal Disease (TAD) affecting livestock production and disrupting regional and international trade in animals and animal products. The detection of FMD antibodies in sheep and goats slaughtered in Karu abattoir suggests small ruminants play important roles in the epidemiology of Foot and Mouth Disease in Nigeria. Good tracking of origin and proper surveillance system for FMD in animals brought into the abbatoir to be slaughtered are recommended for a comprehensive prevention and control of the disease.
I/O-Linearization Based Current Decoupling Control of Modular Multilevel Cascade Converters
Authors: Kalmbach Oliver , Hackl Christoph
Published: February 2023

A generic current control system for modular multilevel cascade converters (MMCCs) is proposed. It is based on (i) input/output-linearization (I/O-linearization), (ii) feedforward disturbance compensation and (iii) parallelized proportional-integral-resonant controllers to compensate for arbitrarily many harmonics (including positive and negative sequence). The controller design is performed in state space. It is generic and flexible and combines pole placement and LQR tuning. Moreover, it allows to take all system parameters such as cluster or output (grid) inductances or resistances individually into account during controller design and tuning. Moreover, the typically imposed simplifying assumptions on system dynamics (e.g., identical parameters) or operating conditions (e.g., balanced loading) can be overcome. The proposed control system is validated for a dual-star bridge-cell MMCC. The simulation results illustrate its excellent control performance under ideal but also non-ideal conditions, where conventional approaches usually fail.
