The study was retrospective-descriptive and consisted of the analysis of the spectrum of infections produced by Klebsiella spp. strains in patients hospitalized in a multidisciplinary hospital as well as the antibiotic resistance pattern of these germs. Klebsiella spp. were identified more frequently in patients hospitalized in ICU (2021: 28,74%; 2022: 40,43%), Internal Diseases (2021: 24,8%; 2022: 15,55%) and General Surgery (2021: 7,87%; 2022: 7,82%) wards being isolated in higher percentages from urine (2021: 44,62%; 2022: 47,21%), respiratory secretions (2021: 25,85%; 2022: 22,71%) and wound secretions (2021: 15,62%%; 2022: 13,28%). Klebsiella species showed higher resistance to cephalosporins and levofloxacin. Most strains of Klebsiella were sensitive to colistin and carbapenems.

The paper presents a study on creating a modular construction based on a simple shaped module. The solution resulted from large research on existing designs, the idea of modular houses having not a long history, but a rich one. The existing solutions helped in formulating a list of requirements that included most of their advantages. The basic module is a square-shaped panel that can be easily personalized according to necessities: a wall with a door or/and windows, ceiling, and floor. The study includes solutions regarding electric wiring and plumbing design for bathrooms or kitchens. The design included solutions for creating different configurations and volumes for the final building involving the designing of connecting modules.

Subacute thyroiditis (SAT) is an inflammatory condition affecting the thyroid gland, usually triggered by a viral infection or occurring after a viral illness. It is characterized by neck tenderness, along with the typical symptoms of thyrotoxicosis and an elevated erythrocyte sedimentation rate. SAT has been identified as a potential complication associated with SARS-CoV-2 infection. The aim of this study is to present and discuss two cases of subacute thyroiditis that occurred following a viral infection, potentially linked to SARS-CoV-2 infection. We describe the clinical, biochemical, and imaging features of two cases of SAT that manifested six weeks after the onset of COVID-19-associated symptoms. Both cases involved female patients, aged 58 and 39, who developed subacute thyroiditis, characterized by neck pain, fever, and fatigue. These symptoms emerged three weeks after recovering from a viral episode marked by acute coryza, cough, and anosmia. Due to a persistent fever lasting three weeks, one of the patients required hospitalization to rule out other infectious causes of prolonged febrile syndrome. Laboratory analyses revealed elevated inflammatory markers, positive serology for SARS-CoV-2 infection, thyroid function tests showed thyroid over-activity and thyroid ultrasound confirmed the diagnosis of SAT. The patients received corticosteroid treatments and beta-blockers, resulting in the complete resolution of symptoms and normalization of inflammatory markers, within three weeks after the SAT diagnosis. Post-COVID-19 thyroiditis can emerge as a potential complication of SARS-CoV-2 infection. It is crucial for clinicians to be aware of this possibility, highlighting the importance of considering post-COVID-19 thyroiditis in patients presenting with relevant symptoms.

The purpose of the paper is to study the heat transfer in the exhaust manifold of a naturally aspirated diesel engine. The work started from the exhaust manifold of the test engine D30 which was redesigned in CATIA V5, then pre-processed in Comsol Multiphysics. The results of the post-processing phase have generated temperature, velocity, pressure, and Reynolds number fields which were compared with experimental data from the engine dynamometric test. For higher accuracy, the temperatures of exhaust manifold surfaces were measured both with IR Camera Imager and thermocouples.

The article aims to give a less theoretical and more practical definition to the tool called Subregion, from which the advantage of directly controlling the stiffness of the scraper slab without bringing an additional load of its own weight to the pilot's head can be concretely demonstrated. Deep foundations will therefore be analyzed. The Subregion is extremely useful in finite element modeling because it helps define caps without breaking the continuous surface of tile elements. This aspect will be covered in detail in the article, such modeling with Subregions leads to high-performance computational models, optimal from the point of view of file sizes. From practice, the author will present two case studies, concluding on the optimal ratio between the precision of the calculations and the volume of probable errors at the level of the results.

In this paper, we obtain the necessary and sufficient conditions for generalized Bessel functions of the first kind zup(z) to be in the classes S(b, λ, β) and R(b, λ, β) of analytic functions with complex order and also give the necessary and sufficient conditions for z(2−up(z)) to be in the classes TS(b, λ, β) and TR(b, λ, β). Furthermore, we give the necessary and sufficient conditions for J(k, c) to be in the class TR(b, λ, β) provided that the function f is in the class Rτ (A, B). Finally, we give conditions for the integral operator G(k, c, z) = ∫0z(2 − up(t))dt to be in the class TR(b, λ, β). Several corollaries and consequences of the main results are also obtained.

We establish fractional versions of generalizations of the Schweitzer, Kantorovich, Polya–Szego, Cassels, Greub–Rheinboldt, and reverse Minkowski inequalities on time scales. We present that fractional P´olya–Szego’s dynamic inequality generalizes Cassels’ inequality. Time scales calculus unifies and extends discrete, continuous, quantum versions of results.

In this article, we give a new version of n-tuple diamond-alpha H¨older inequality on time scales, this result generalizes some results known in the literature. Second, we present n-tuple diamond-alpha inequality with two parameters on time scales. It is a tool to generalize integral inequalities on time scales, its goal is to create an inequality restarted from the left side with a parameter to a right side with two parameters. Moreover, new Minkowski integral inequality with two parameters is given, and some interesting integral inequalities are found.
