The article considers the effect of the FITODOC® Carnitine feed additive on the clinical characteristics, hematological and biochemical parameters of piglets during the rearing period and fattening pigs with toxic liver dystrophy at a dose of 1 ml and 2 ml per liter of water. There was a reduction in the time of disappearance of clinical manifestations and an increase in body weight; an antianemic effect was noted, which is expressed by an increase in the number of red blood cells and the level of hemoglobin; a decrease in the level of hepatic markers, such as total bilirubin, AlAT, AsAT, and ALP; a decrease in the activity of acute-phase globulins alpha 1 and 2. It is recommended to use the feed additive mainly in groups of growing animals with functional liver disorders at a dose of 1 ml of feed additive per 1 liter of water for 14 days, since at this dosage the maximum effect is achieved in animals of this age group.

The purpose of the research was to study the reproductive qualities of Landrace pig lines bred in JSC Rassvet in the period from 2015 to 2017. The productive qualities of pig lines were evaluated by the normal farrowing of sows and indicators of the reproductive qualities of boars. To assess the indicators of reproductive qualities of sows, the index ‒ J3 was developed, which includes the number of live piglets after farrowing, the weight of piglets at weaning, and the number of piglets at weaning. The indicators of the J3 index were adjusted for the alignment of the litter. The index of evaluation of indicators of reproductive qualities of boars, includes indicators of the index of commodity mass of the nest J3 for sows born with a boar and the percentage of fertilization of sows. It was found that the Landrace pig line of French origin has a higher multiplicity and the number of piglets at weaning, but lower milk content. The analysis of correlations of reproductive qualities of sows showed a significant influence of technological factors on the reliability of the assessment of breeding value and confirmed the need to use correction factors for the alignment of the litter.

Published: August 2021

It is well known that the wavelets have widely applied to solve mathematical problems connected with the differential and integral equations. The application of the wavelets possess several important properties, such as orthogonality, compact support, exact representation of polynomials at certain degree and the ability to represent functions on different levels of resolution. In this paper, new methods based on wavelet expansion are considered to solve problems arising in approximation of the solution of heat equation with involution. We have developed new numerical techniques to solve heat equation with involution and obtained new approximative representation for solution of heat equations.

This paper presents an investigation on cooling effect and flow structure of the spherical dimple configuration during air flow on the Aluminium surface. It is prominently known that applying dimples profile causes an enhancement in heat transfer over a plain surface. A three level of Box-Behnken response surface methodology was performed to find the correlation between the input and output variables. A total of 17 different combinations of these inputs were performed throughout the experiment. The variable inputs to be investigated namely: dimple diameter of 10 - 14 mm, dimple orientation angle of 60°- 90°, and airflow velocity of 16 - 18 m/s to observe the response on the cooling time. The Aluminium block was heated to 60°C and cooled down by air flow at room temperature. The ANOVA was used to identify the significant effect of each parameter. CFD software was used as a simulation tool to analyze the flow structure and Reynolds number that associate with the heat transfer rate to support the statistical findings. Based on the result, all the input parameters are found to be significantly dominated by air flow velocity. Staggered arrangement dimple profile surface improves cooling effect by 63% over the plain flat surface. The increment in Reynolds number will increase the heat transfer which then shortening the cooling time.

A Call to Diversify the Lingua Franca of Academic STEM Communities
Authors: Henry Kaylee , Virk Ranya , DeMarchi Lindsay , Sears Huei
Published: August 2021

The current bias in the STEM academy favors English-language research publications, creating a barrier between English-speaking and non-English speaking researchers that is detrimental to the continuity and evolution of STEM research. In this paper, we lay out policy measures that employ U.S. government resources to create infrastructure that standardizes and facilitates the language translation process and hosting of multilingual publications. This proposal aims to increase linguistic diversity in academic STEM publications for the ultimate goal of improving global scientific communication and ameliorating the existing disparity between English and non-English STEM literature.

Ensuring Social Impact at Every Stage of Technology Research &
Development
Authors: Pesner Jeremy
Published: August 2021

Although the United States national innovation system has produced many
technologies, their benefits are not evenly distributed across the country’s
population. This stands in direct contrast to the aims of government, which
frequently funds science research for the purpose of social benefit. This
paper first undertakes a deep reconsideration of the US national innovation
system, and then reframes it as a collective impact initiative in order to
coordinate every one of its contributors around this goal. It begins by
tracing the origins of the longstanding tensions between science undertaken
for the sakes of science inquiry versus societal benefit. It then discusses
the inadequacies of practices meant to bridge science outcomes and societal
needs like the broader impacts and technology transfer. It concludes by
proposing a significant expansion of the stakeholders that evaluate the
proposals and outcomes of federally funded research. This integrates diverse
public participation into the proposal selection process, research
discussions, and technology transfer to ensure that universal social impact
is routinely considered.
The Federal Science Project: A scientist in every classroom

Published: August 2021

The United States urgently needs science-based solutions for a multitude of policy issues, and a basic societal understanding of science is essential to gaining public trust and addressing these issues. However, there is a disconnect between professional scientists and engineers and K-12 science education. Many students will graduate after 13 years of school having never met a scientist. This missed opportunity is not an issue of supply. There are over 7 million practicing scientists and engineers in the U.S.; if every scientist spent just one hour a year in a classroom, each student would get at least three visits from a scientist every single year. Here, we propose the Federal Science Project: a federally funded, nationwide program to bring scientists into all K-12 schools across the U.S. with the goal of reaching every student, regardless of geographic location. Scientists and engineers across disciplines and sectors would undergo training in communication skills and cultural competency, connect with classrooms via a national database with support from full-time staff, partner with teachers to deliver interactive lessons aligned with existing curriculum and standards, and receive appropriate compensation. Close partnerships between scientists, engineers, teachers, policymakers, and community partners in science education (science centers, museums, etc.) would invigorate the trust-based connections needed for 21st-century science education and policy transformations.

Günümüzde çoğu insan çalışma alanı olarak ofislerde zamanının büyük bir bölümünü geçirirler. Bu nedenle ofis ortamında çalışanlar için ergonomi oldukça önem arz etmektedir. Ergonomik olarak tasarlanmış bir ofis ortamının gerek çalışan psikolojisi gerekse iş verimliliği açısından önemli olduğu bir gerçektir. Çünkü bu kavramla çalışanın daha huzur verici bir ortamda çalışması sağlanır. Genellikle ekranlı araçlarla yapılan işlerde çalışanlar uygun olmayan ofis ortamlarından dolayı ciddi sağlık ve güvenlik problemleriyle karşı karşıyadır. Bu nedenle uygun olmayan işyerlerinde çalışanlar için bir takım mesleki kas iskelet sistemi rahatsızlıkları meydana gelebilir. Bu durum hem çalışanın motivasyonunu hem de iş verimliliğini azaltır. Türkiye’de yürürlüğe giren “Ekranlı Araçlarla Çalışmalarda Sağlık ve Güvenlik Önlemleri Hakkında Yönetmelik” ile bu konunun yasal zemini hazırlanmıştır. Bu yönetmelikte yer alan hükümlere uyulan ofislerde, çalışanların sağlık ve güvenliği korunarak meydana gelebilecek iş kazası ve meslek hastalıkları önemli ölçüde azalabilecektir.

Published: August 2021

Atıkların bertarafı ve arıtılması sırasında açığa çıkan kimyasallara maruz kalma, giderek artan bir şekilde potansiyel iş sağlığı sorunu olarak kabul edilmektedir. Atık yakma fırını çeşitli toksik maddeleri yayması ve yakma fırını çalışanların bunlara maruz kalmaları nedeniyle çalışanların sağlığı için tehlike arz etmektedir. Bu nedenle maruziyet seviyeleri dikkatlice ölçülmelidir. Bu durumlarda biyolojik izleme, personellerin gerçek mesleki maruziyetinin tanımlanması ve ilgili sağlık etkilerinin önlenmesi için temel bir tamamlayıcı araç olabilir. Çalışanlarda, çok düşük maruziyet seviyelerinde, sağlık riski değerlendirmesi için hassas ve spesifik biyolojik belirteçlerin geliştirilmesi ve kullanılması konusunda artan bir ilgi vardır. Metale maruz kalan personellerin biyo-izlenmesi üzerine literatürde çok sayıda makale bulunmasına rağmen, atık arıtma faaliyetlerinde kullanılan makalelerde sonuçlar bazen tutarsızdır. Sonuçlar, atık yakma tesislerinin personellerinde ölçülen metal seviyelerinin, Kadmiyum ve Kurşun için bazı önemli istisnalar dışında, genellikle düşük olduğunu göstermektedir. Gelecekteki çalışmalar hem biyolojik hem de çevresel izlemeyi kullanan bir yaklaşıma odaklanması önem arz etmektedir. Metal içeren tozların farklı granülometrik fraksiyonlarının, yani solunabilir, torasik, solunabilir ve ultra ince fraksiyonların ölçümüne özel bir vurgu yapılmalıdır.

La compétition internationale en recherche et développement
Authors: Papon Pierre
Published: August 2021

Alors que les États-Unis retrouvent une activité diplomatique classique depuis l’arrivée de Joe Biden à la Maison Blanche, et que Pékin manie de plus en plus le soft power pour renforcer sa position sur la scène internationale, les enjeux de puissance à l’échelle mondiale reposent et reposeront sans doute de plus en plus sur les capacités des États à s’imposer en matière scientifique et technologique. Technologies de l’information, conquête de l’espace, intelligence artificielle, recherche médicale…, sont autant d’enjeux d’avenir dans lesquels il s’agit désormais d’investir efficacement. Or, comme le montre ici Pierre Papon, la France est sur une pente déclinante en la matière. Les moyens financiers consacrés à la R&D stagnent depuis plusieurs années et malgré des incitations fiscales généreuses, les entreprises ne parviennent pas à s’élancer dans la compétition scientifique internationale avec suffisamment de vigueur pour rivaliser avec les leaders mondiaux. À l’heure où les modalités de la relance économique post-crise Covid sont encore à définir, il est urgent de relancer les efforts publics et privés de R&D, de donner à la France les moyens d’exister sur le plan scientifique et technologique, et de cibler les secteurs stratégiques des années à venir. Le diagnostic présenté dans cet article est un signal d’alarme pour que l’on trouve rapidement le remède à ce décrochage français en matière scientifique.  S.D.

We report macro and meso palaeobotanical records from the Zarzal Formation, in the Cauca River Depression, and the Quindío-Risaralda Basin between the Western and the Central Cordilleras of Colombia. The fossils correspond to leaves and seeds obtained from layers of mudstones, diatomites, and tuffaceous sandstones deposited in the inter-Andean valleys of Cauca and La Vieja rivers, separated by the Serranía Santa Bárbara ridge between the Valle del Cauca and Quindío departments. The sediments of the Pleistocene Zarzal Formation were deposited in a fluvial-lacustrine environment, with volcanic influence originated in the Central Cordillera to the east of the depositional area. The study here presented allowed the identification of thirteen morphotypes of leaf impressions grouped in six Angiosperm families: Poaceae?/Cyperaceae? and Araceae of the Monocots group, Melastomataceae, Fabaceae and Lauraceae belonging to the Eudicots group and one family of Lycopsida: Thelypteridaceae. On the other hand, very well-preserved silicified micro-seeds were grouped in eight morphotypes, belonging to the botanical groups Cyperaceae and Asteraceae. The fossils found allowed us to identify two types of plant associations that exhibit paleofloristic richness. In the Cauca River Basin, an autochthonous to parautocthonous plant association could correspond to a sub-Andean gallery forest, whilst in the La Vieja River Basin a parautocthonous plant association indicates a swamped floodplain. Keywords: paleoflora, leaves, seeds, Cauca River, La Vieja River, lacustrine deposit.

The unusual association of fish and crabs from Romualdo Formation, Aptian–Albian of the Araripe sedimentary Basin, NE Brazil. In a study and collection of fossils from the Romualdo Formation in “Araripe pernambucano”, an association of Vinctifer comptoni and Rhacolepis buccalis with eubrachyurans and orithopsids crabs was observed in four calcareous nodules. Associations were discussed based on ecological and taphonomic hypotheses. It is noted from the degree of articulation of the organisms, that either the death or the availability of crab moults in the sediment possibly occurred before the death of the fish. In addition, the fish do not have teething consistent with feeding on crabs. Thus, this association would occur due to fossilization processes and not due to ecological interactions. The study also emphasized systematic and paleogeographic aspects of the groups. Romualdocarcinus salesi is probably related to the “higher” true crabs (Eubrachyura), a hypothesis already raised in previous works, due to the preservation of its dorsal carapace next to a pleon of subquadrangular shape similar to those seen in this group. The occurrence of Exucarcinus gonzagai associated with fish, in concretions in the shales, can raise the question of E. gonzagai and Araripecarcinus ferreirai species as synonyms. The data obtained with the survey of the paleogeographic distribution of fish and crabs in geological formations of correlated age corroborates the hypothesis of the Tethyan marine influence in Araripe.

Heart rate variability (HRV) and cardiorespiratory phase synchronization (CRPS) were employed to study the cardio- and respiratory interactions in patients with asthma receiving inhalation of beta2-agonist (Berotec 200 mcg) for routine bronchodilator test. Both time- and frequency-domain parameters were used to analyze the HRV. A weighted G-index was introduced to study the quality of the CRPS. The HRV parameters, in both the time and frequency domains, exhibited significant changes pointing to a sympathetic activation of the autonomic balance immediately after the inhalation. On the other hand, the CRPS index barely changed throughout the entire process. This indicates that inhalation of beta2-agonist does not alter the CRPS appreciably, and that the CRPS, in contrast to HRV, is relatively stable in response to the inhalation of beta2-agonist in patients with asthma.
Disseminated Nocardiosis Coinfection with Extrapulmonary Tuberculosis in a Patient with Metastatic Thymoma

Published: August 2021

Patients with metastatic thymoma postintensive chemotherapy and radiotherapy are prone to opportunistic infectious diseases. Disseminated nocardiosis is a rare disease; however, its incidence has increased in recent years due to the growing population of immunocompromised hosts. We present the first report of Nocardia beijingensis infection with extrapulmonary tuberculosis coinfection causing muscular and brain abscesses in a patient with metastatic thymoma postintensive chemotherapy and radiotherapy. This case illustrates the possibility of coinfection with two pathogens and the difficulty in establishing a rapid diagnosis. Awareness of opportunistic infections and the early initiation of appropriate antibiotic therapy are important for the treatment of immunocompromised patients with infectious diseases.

Published: August 2021

Background:

There is still an unresolved debate about whether ureteroscopy (URS) and biopsy are required as a routine for the diagnosis of upper tract urothelial cancer (UTUC) or if these procedures can be omitted in appropriately selected patients. We aimed to report the overall diagnostic accuracy of URS biopsy for ureteral tumors in concordance with the final histopathology.

Materials and Methods:

We conducted this retrospective study from 2000 to 2019. Data on URS biopsies for ureteral tumors which included pathological diagnosis, staging, and grading were collected. These data were then compared to the results of contrast-enhanced computed tomography (CT) and the final histopathological reports.

Results:

The data of 275 patients with a mean age of 59 ± 11 years were collected. Complete data regarding URS biopsies for ureteral tumors were available in 94 cases with an overall diagnostic accuracy in detecting malignancy of 93%. When matched to the final histopathology, the accuracy of URS biopsies increased as the tumor grade increased. Upgrading was noticed in 36% of the biopsies. Biopsy grade was an accurate predictor of stage. CT was performed in 270 cases with an overall accuracy of 96%. URS did not affect post-UTUC intravesical recurrence (P = 0.9) or overall survival (log rank = 0.08).

Conclusion:

URS biopsy for ureteral tumors was highly specific with fair predictive ability for tumor grade, and it could predict tumor stage. URS may not increase intravesical recurrence or affect overall survival. However, false-negative results were noted, which did not change the surgical plan when radical surgeries were decided based on CT.
Decreased Visual Acuity after Chemotherapy in a Case with Diffuse Large B Cell Lymphoma

Published: August 2021

A 53-year-old male with no past medical history presented with abdominal pain for 2 days, accompanied with fever and poor appetite. Leukoerythroblastosis along with elevated lactate dehydrogenase and a bone marrow exam led to the diagnosis of diffuse large B-cell lymphoma, germinal center B-cell (GCB) type. After the 5th cycle of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone, progressively decreased visual acuity along with left ptosis occurred. Drug-related optic neuropathy was suspected, and initial magnetic resonance imaging (MRI) and cerebral spinal fluid (CSF) studies revealed negative results. However, meningeal lymphomatosis with bilateral optic nerve infiltration was finally diagnosed by subsequent MRI and CSF studies after 1 month. This rare case highlights the pitfalls of CSF studies. Based on previous studies, an adequate sample (>10.5 ml), rapid processing within 1 h, and serial testing at least twice can improve the rate of positive results while reducing the false-negative rate. We hope that this case can remind clinicians of the possible diagnosis of lymphomatous optic nerve infiltration from systemic lymphoma, and that properly conducted CSF studies can help to avoid missing this diagnosis.

Background:

5-fluorouracil (5-FU) is a widely used antimetabolite drug for the treatment of a variety of cancers. It is associated with side effects and toxicities, most of which have been extensively studied. However, data related to potentially life-threatening cardiotoxicity, and especially bradyarrhythmias, are lacking in the literature.

The aim is to

assess potentially life-threatening bradyarrhythmias (or bradycardia) in patients on continuous 5-FU infusion.

Materials and Methods:

Fifty-four patients with esophageal carcinomas were included in this prospective non-randomized observational single-institution study. All of the patients underwent concurrent chemoradiation in curative settings over a period of 30 months (January 2015–June 2017).

Results:

Fourteen of the 54 patients developed bradycardia during continuous 5-FU infusion. Chemotherapy (CT) was stopped transiently in one of these patients and then continued uneventfully after the return of normal heart rate. The other 13 patients developed severe bradycardia, and CT was stopped completely and switched to other cardiac-safe CT protocols due to persistent bradycardia despite optimal management as per the institutional protocol. One patient died of sudden cardiac arrest during continuous 5-FU infusion.

Conclusion:

The persistence of life-threatening bradycardia during 5-FU infusion should prompt physicians to switch to other cardiac-safe CT protocols. Patients should be vigilantly monitored for any electrocardiography changes during continuous 5-FU infusion.
Vitreoretinal abnormalities in corona virus disease 2019 patients
Authors: Sutandi Nathania , Lee Felix
Published: August 2021

The coronavirus disease 2019 (COVID-19) has become a global pandemic since December 2019. Although COVID-19 primarily affects the respiratory systems, it has become abundantly clear that it involves multiple organs including the heart, kidney, skin, and brain. Neuro-ophthalmic signs and anterior segment inflammation of the eyes were documented in COVID-19 patients recently. Small but growing number of literatures has also reported the cases of new onset vitreoretinal disorders related to COVID-19 infection. A comprehensive search from four online databases was done. Findings show vitreoretinal involvement in COVID-19 patients including the central retinal vein occlusion, central retinal artery occlusion, reactivation of previous uveitis, chorioretinitis, macular hemorrhage, acute macular neuroretinopathy, paracentral acute middle maculopathy, vitritis with outer retinal abnormalities, varicella zoster virus-related acute retinal necrosis in immunocompromised patient, and other posterior segment pathological changes. The hypotheses for potential pathogenesis of these manifestations are direct viral ocular infection and thromboembolic complications secondary to the hyperinflammatory response. This is the first review article, which provides an overview of current evidence regarding the vitreoretinal manifestations in COVID-19 patients.
