On the dynamic thermal conductivity and diffusivity observed in heat pulse experiments
Authors: Fehér Anna , Kovács Róbert 
Published: March 2024

Abstract
Determining the thermal properties of materials with complex structures is still a major engineering challenge today. The well-known heat pulse experiment can be used to determine the thermal diffusivity by measuring the temperature history as a thermal response for a fast excitation. However, the evaluation of the measurements can be challenging, especially when dealing with non-homogeneous samples. The thermal behavior of such heterogeneous materials may exhibit a response including two-time scales. Therefore, the Fourier equation is not necessarily applicable. The simplest possible alternatives are the 2-temperature models the Guyer–Krumhansl and Jeffreys heat equations. In the present paper, we focus on the interpretation of the Jeffreys heat equation; studying its analytical solution, we present a fitting method for determining the unknown parameters. We also discuss its relation with the other two heat equations, and we offer an interpretation of how to characterize the transient response of heterogeneous materials.

Published: March 2024

Abstract
This article contains theoretical investigation of the performance of the coupler comprising laser diode and mono-mode circular core triangular index fiber (TIF), which contains on its tip an upside down tapered hyperbolic microlens (UDTHM). Here, we take care of probable angular and transverse mismatches. In our derivation, we use the refractive index distribution in the tapering area, the ray equation, and the relation involving refraction by hyperbolic microlens. We report analytical formulation of coupling efficiencies in the presence of specified types of misalignments using a relevant ABCD refraction matrix for a UDTHM in the vertical plane. In the fields of lasers and fibers, we use Gaussian field distribution in our analysis. Our research is based on two widely employed wavelengths, 1.3 µm and 1.5 µm. In this study, we used three TIF with V numbers of 4.380, 3.511, and 1.924, respectively. Little computation is required to execute the prescribed formulations. This study surfaces the sensitivity of the coupler in presence of the aforementioned types of offsets. The found results will prove valuable to manufacturers working in the domain of UDTHM.
A multimodal translation analysis of online app advertisements: the case of Careem as a Taxi-sharing app in Iraq
Authors: Qadoury Abed Ahmed , Jarjees Wadia Sura 
Published: March 2024

Abstract
This research presents a multimodal translation analysis of 20 online advertisements (Ads) for Careem App from Arabic into English. It tries to examine what effects the multimodal elements have on the translation of these Ads; this can be done by shedding light on the similarities and differences of the verbal and visual contents on the one hand, and the consequent effects in rendering from Arabic into English, on the other. The analysis has shown that some mismatching was done by the translator in neglecting the message of the Ads by changing the linguistic content, without taking into consideration the relationship between the textual and visual contents. Examples of mismatching idioms, expressions, and collocations related to the Iraqi culture were found. Also, some Ads were identical in their visual elements, but the verbal content of the translated ones failed to convey the meaning of the source Ads due to cultural differences. The study has also found that the textual-visual relationship is not realized in most of the translated Ads on the word, and above word level. This, in turn, has a direct influence on the textual level; and has consequently led to instances of mismatching in rendering the whole meaning of the target message.

Published: March 2024

Abstract
Art-based interventions are increasingly employed in workplace settings for the purposes of organizational training and development. In this article, we examine the implementation of a workshop where hand drumming is used in two client organizations. Through the detailed analysis of the trainers’ actions, the article shows how the trainers use the combination of verbal and embodied means in order to instruct and encourage participation in joint drumming. In particular, the article demonstrates how the trainers’ instructive practice change across the instructional phases of the workshop and form a trajectory from pre-planned rhythm patterns to free collective improvisation in the pre-designed service product.

Published: March 2024

Abstract
The manuscript reports the synthesis of Dy3+ incorporated lithium magnesium borate glass by melt quenching technique. FTIR study revealed the presence of both BO3 as well as tetrahedral BO4 units through their characteristic frequencies. Photoluminescence (PL) study of unirradiated samples confirmed the presence of Dy dopant in the ‘+3’ oxidation states from the characteristic emissions at 482, 578, 666 and 716 nm corresponding to 4F9/2 → 6H15/2, 4F9/2 → 6H13/2 and 4F9/2 → 6H11/2, 4F9/2 → 6H9/2 transitions, respectively. Thermal neutron and gamma irradiated PL emission and lifetime characteristics were discussed in details based on the different defect centers. Thermal neutron irradiated TL study showed that the material has a broad and single dosimetry glow peak at about 450 K which showed high fading due to low temperature peak. TL based neutron sensitivity of LMB: Dy3+ was found to be about 37.4 times less than that of standard TLD-100 (LiF: Mg, Ti) powder. The net TL response from about 3 to 83 mSv of neutron dose was found to be linear (Adj. R2 = 0.9994) which is one of the most desirable properties for dosimetry applications. In addition, the TL trap parameters were evaluated using both deconvolution of TL glow curve and peak shape method as suggested by Chen which were found to be matching with each other.

Abstract
Formaldehyde is one of the most common indoor air pollutants that seriously damage human health. It is of significant importance to effectively remove indoor formaldehyde. In this work, a novel cement-based composite with ZIF-8@TiO2-coated activated carbon fibers (TiO2-ACFs) was prepared and shown to remove the indoor formaldehyde effectively. TiO2 was coated on ACFs via atomic layer deposition, and then ZIF-8 was grown on the surface of TiO2-ACFs. The ZIF-8@TiO2-ACFs were then mixed with cement slurry and thus formed a cement-based composite, which exhibited excellent formaldehyde removal performance. In particular, if assisted with UV light, the removal efficiency for formaldehyde by the cement-based composite showed an obvious increase.

Abstract
In recent decades, nanomedicine has attracted much attention at the forefront of nanotechnology, gaining great expectations in the biomedical sectors. Among various nanomaterials, silica nanoparticles-based drug delivery is considered effective owing to their physicochemical stability and biological compatibility. Surface grafting and chemical conversion techniques were used to create an amphoteric functional ligand known as amidoxime ligand (AL) modified mesoporous silica material (MS-AL NPs). With this technique, amidoxime ligand groups can be introduced in greater concentration to the silica surface without compromising its structure. The active surface allows for surface functionalization and integration of medicinal substances. They are widely employed in the bio-medical industry for diagnostics, target administration of drugs, bio-sensing, cellular absorption, and so on. The function of the produced MS-AL NPs as a regulated drug delivery system was studied utilizing doxorubicin (Dox) as a model anticancer drug. Using the MCF-7 cell line, the biocompatibility and cellular uptake characteristics were investigated. Considering all factors, the MS-AL NPs may be used as pH-responsive drug carriers in cancer treatment applications.

Published: March 2024

AbstractWe report a case of exposure to Coxiella burnetii in a surgical nurse who underwent an injury of her finger with a scalpel blade during a native aortic valve replacement with a bio-prosthetic cardiac valve conducted on a patient suffering from C. burnetii aortic endocarditis. Given the positivity of C. burnetii culture and PCR from the patient's aortic valve, she was prescribed prophylactic doxycycline 100 mg twice a day for 10 days. Q fever is an occupational zoonosis resulting usually of exposure to infected animals by inhalation of infected aerosols or consumption of contaminated raw milk. Apart from materno-foetal transmission, about 180 cases of human-to-human C. burnetii transmission have been published from 1949 to today, including transmission by blood transfusion, sexual relations, transmission in the healthcare setting to staff, patient attendants and other patients that were likely infected from inhalation of aerosol from respiratory or placental products, transmission to staff during autopsies of patients with Q fever and transmission in familial settings. As C. burnetii is a highly infectious bacterium, that may cause infection with a low inoculum, it should be added to the list of organisms which may be of concern following blood exposure among healthcare professionals.

Background: Laboratory tests are integral to the medical decision-making process. Blood vacuum tubes need to be validated to increase the analytics quality. This study aimed to compare various vacuum tube brands that use serum clot activator and serum separator tube (SST) for clinical chemistry and hormonal parameters, K3EDTA anticoagulant for hematological parameters, and citrate for hemostasis parameters.
Methods: The comparative study was carried out cross-sectional in the Department of Clinical Pathology, Dr. Cipto Mangunkusumo National Public Hospital, on June 20, 2020. There were 20 subjects for each type of tube. The control tube was BD Vacutainer®, and the test tubes were Samplix®, VACUETTE®, Vacusera®, and YCHD.
Results: Underfilling was the most common problem in preanalytical observation. This problem for citrate tubes was most frequently found in Vacusera® tubes. The possible cause of underfilling is the expiration date, which was close to the date of the experiment. There was a significant difference in PT results (p <0.0001) in the Vacusera® citrate tube. All tube brands had no significant differences in all clinical chemistry, hormonal, and hematological parameters (P>0.05). After 24 hours at room temperature, the results of hematological parameters showed statistically significant differences in MCV and hematocrit parameters, while other parameters were still within the CV limit of the instrument.
Conclusion: There were no significant differences in the results of clinical chemistry, hormonal, and hematological parameters for all tube brands. A hematology parameters test should be done immediately as the delay may affect the MCV and hematocrit parameters.

Background: perforated peptic ulcer is still a challenge for surgeons and requires a strategy to provide a good outcome. Currently, research on protective biomaterials still has limitations. Free peritoneal patch has growth factors, is antimicrobial, and increases angiogenesis and progenitor properties, which is useful for wound healing. This study examines the healing of primary gastric suturing with peritoneal patches in peritonitis conditions by measuring bursting pressure.
Methods: Researchers conducted an experimental study using 30 New Zealand White Rabbits induced by fecal peritonitis. An artificial perforation with a diameter of 1 cm in the gastric corpus was performed, and primary suturing was performed using 5/0 silk thread with 2 simple sutures. In the treatment group, a free peritoneal patch was added. The bursting pressure examination was carried out on the 7th postoperative day.
Results: Changes in the body weight of the rabbits before and after surgery reflecting the nutritional status of the sample did not significantly affect the value of bursting pressure (p>0.05). Meanwhile, the value of bursting pressure in the primary gastric suturing group with a free peritoneal patch was significantly higher than in the primary gastric suturing group without adding a free peritoneal patch (p<0.05).
Conclusion: A free peritoneal patch can be used as a biological dressing to prevent leakage in gastric primary suturing in conditions of peritonitis, as shown by higher bursting pressure values.

There are several factors involved in its pathogenesis including insufficient dietary habits and fluid intake. Therefore, we conducted a systematic review and meta-analysis to compare between dietary intake across populations and recurrent urinary tract stones. This systematic review and meta-analysis aims to compare the associations between dietary intake across populations and recurrent kidney stones.
Methods: Systematic search up to March 2023 were conducted through PubMed, Scopus, EMBASE. The systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Means and standard deviation of the nutrient intakes were extracted in patients with urinary stone disease group and control group.
Results: Seven articles were further assessed with two articles were assessed through meta-analysis. Two studies showed that high sodium intake [SMD = 0.29 95% CI = -0.13, 0,71] was found in patient with urinary stone disease, while high water intake [SMD = -0.40 95% CI = -1.14, 0.34] was found in the control group.
Conclusion: Animal protein, processed meat, sodium, and sugary beverages were associated with an increased risk of developing urinary stones, whereas vegetable protein and water intake were associated with a decreased risk.

Background: Ewing’s sarcoma is the second most common primary bone tumor presenting in childhood and adolescence. Ewing's sarcoma of the skull bones is an unusual occurrence (6 to 9% of all Ewing’s. sarcoma cases). Here, we present a rare case of Ewing's sarcoma involving the central nervous system (CNS) in a 13-month-old child and share our experience with its management.
Case Presentation: We report a case of a 13-month-old girl with a chief complaint of gradually progressive head size. There is a history of seizures once a week before admission. The head CT scan with contrast administration revealed non-communicating hydrocephalus with bone defect in the occipital region and an intraaxial tumor of the posterior fossa due to Ewing’s sarcoma.
Conclusion: Primary cranial Ewing's sarcoma of the cranium is a rare occurrence; its extension to intraparenchymal is even rare. This diagnosis can be considered in the differential diagnosis in children with a tumor involving the skull with destruction of the bone.

Introduction: Impaired platelet production is one of the causes of thrombocytopenia. Immature platelet fraction (IPF) shows the proportion of young platelets in peripheral blood. A decrease in the number of young platelets reflects a decrease in the thrombopoiesis process. This suggests that young platelets can be a marker for measuring megakaryopoiesis activity. This study aimed to determine the diagnostic value of IPF.
Methods: The sample will be divided into two groups; groups suspected of production disturbances and groups not suspected of production disturbances. In the group with suspected production disorders, bone marrow aspiration (BMA) will be carried out to determine a definitive diagnosis. Meanwhile, in the group not suspected of production disruption, bias work-up will be carried out. After that, descriptive statistical analysis, ROC analysis and diagnostic tests will be carried out.
Result: This study used 81 cases of thrombocytopenia with a proportion of 49 (60.5%) in the production disorder group and 32 (39.5%) in the non-production disorder group. The IPF% value in the production disruption group is significantly lower than the non-production disruption group 3.1% (0.3-21.4) vs 13% (2.0-49.2) p value <0.001. The results of calculations using ROC analysis in this study showed an AUC of 0.917 (95% confidence interval (CI): 0.853-0.981, p<0.001). The results of the analysis set a cut-off value of 7.5% at sensitivity 83.7%, specificity 84.4%, PPV 89.1%, NPV 77.1%, LR+ 5.53, LR- 0.19, prevalence 60.4%, and 83.9% accuracy.
Conclusion: The results of this study showed that IPF% AUC was 0.917, indicating that IPF% was very good for distinguishing production disorders from theombocytopenia with an accuracy of 83.9%.

Background: Ventricular septal defect (VSD) is the most common congenital cardiac anomaly in children and the second most common in adults. It often coexists with other cardiovascular conditions, including hypertension, coronary artery disease (CAD), and heart failure. This presents unique challenges in diagnosis and treatment.
Case Presentation: We present the case of a 46-year-old woman with a previously undiagnosed VSD complicated by a ventricular septal rupture and prior myocardial infarction. Coronary artery bypass grafting (CABG) and VSD repair were performed. Unexpectedly, the VSD turned out to be an atrial septal defect (ASD) of the muscular type. The repair was successful using mattress sutures and a 0.6mm PTFE patch. Two-coronary-artery bypass was also performed. The patient's recovery was uneventful, with no residual VSD.
Conclusions: Discovering a large, asymptomatic VSD in an elderly patient is uncommon. Simultaneous repair of VSD and CAD yields favorable surgical outcomes, highlighting the importance of thorough preoperative evaluation in such cases.
