Technological evolution has contributed to considerable changes in the learning methods used today. If a few years ago, before the technological boom, students relied only on their memory capacity, on notes on sheets of paper and written materials (in the form of course materials, books, or textbooks), today the process of learning is significantly facilitated by the means and techniques involved in the use of technology, such as artificial intelligence, smartphones, and tablets, which are rapidly ...

In a constantly evolving society, marketing technology (MarTech) is part of the foundation of efficient business practice and market success. The aim of our research is to understand and theorise the antecedents of MarTech adoption for Romanian companies. We have developed an empirical model based on structural equations to predict the behavioural intent of users to adopt MarTech-type technologies. The results obtained in this article highlight the most used categories of MarTech tools and the factors ...

Cervical cancer is one of the most common cancers in women in developing countries, second only to breast cancer, with more than 450.000 new cases every year. Romania has the highest incidence of cervical cancer in Europe; more than four times the incidence found in Western Europe. Radiotherapy with or without chemotherapy is considered in most countries the gold standard for locally advanced cervical cancer. In Romania, if downstaging occurs after radiotherapy, adjuvant surgery is routinely performed. ...

Bone defects are commonly seen in clinical practice. They are caused by different types of trauma, infections, congenital malformations and cancers. Current approaches to skeletal reconstructive surgery use biomaterials, autografts or allografts. The aim of this study was to analyze bone repair from histologic point of view. To study the repair of bone defects, we used two batches of Wistar mices (Lat Rattus Norvegicus). The 46 subjects under study were divided into two equal lots. In all subjects, ...

Hard coatings based on the multiphase W-Ti-Si-C system have been obtained by combined magnetron sputtering and ion implantation process (CMSII). The coatings have been produced from complex targets having a variable SiC content (5 and 10 wt.-%). Their characterization included chemical and structural analysis by X-ray diffraction (XRD), and glow discharge optical emission spectrometry (GDOES), scanning electron microscopy (SEM) investigation, and microhardness measurements. The coating produced from ...

Despite advances in fetal monitoring during labor, one of the most critical causes of neonatal death and neurologic injuries remains intrapartum asphyxia. Umbilical cord gases can be used to detect acidosis and fetal distress. We conducted a retrospective, multicenter study to evaluate umbilical cord blood pH and lactate as a mean of evaluating the degree of intrapartum hypoxia and also to establish which of the two is more reliable in predicting morbidity in term neonates. The present study utilized ...

MRONJ (Medication-Related Osteonecrosis of the Jaw) is a condition observed in a subset of cancer patients who have undergone treatment with zoledronic acid in order to either prevent or treat bone metastases. The primary aim of this research was to establish the importance of risk factors in the development of medication-related osteonecrosis of the jaw in cancer patients receiving zoledronic acid therapy for bone metastases. The present study is an observational retrospective investigation conducted ...

Stress urinary incontinence affects a large proportion of women in their lifetime. The objective of this review was to describe and compare the latest surgical trends in urinary incontinence and focus on the literature advantages, disadvantages, complications and efficacy of surgical procedures regarding this pathology. Using network meta-analysis, we have identified the most frequently used procedures (Burch surgery, midurethral sling and pubovaginal sling), and we have described and characterized ...

The aim of this work is to comparatively analyze, using numerical simulation, the impact behavior of aramid fabric. A layered panel was impacted by two projectiles specific to the NIJ protection level HG1. The protection level in this study is based on NIJ Standard 0123.00. This standard is used to establish protection levels. The two projectiles specific to the NIJ HG1 protection level are 9 mm Luger and .357 Mag FMJ. Law enforcement personnel use body armor designed to protect the torso. With the ...

The continuous variability of SARS-CoV-2 and the rapid waning of specific antibodies threatens the efficacy of COVID-19 vaccines. We aimed to evaluate antibody kinetics one year after SARS-CoV-2 vaccination with an mRNA vaccine in healthcare workers (HCW), with or without a booster. A marked decline in anti-Spike(S)/Receptor Binding Domain (RBD) antibody levels was registered during the first eight months post-vaccination, followed by a transitory increase after the booster. At three months post-booster ...

Appendiceal endometriosis is a rare entity and, when accompanied by intestinal metaplasia, represents a challenging differential diagnosis with low-grade appendiceal mucinous neoplasm (LAMN). We present the case of a 47 years-old woman, with multiple surgical interventions for endometriosis, with persistent symptoms despite chronic hormonal treatment, with imaging showing stage IV endometriosis. Hence, en bloc low rectum resection with total hysterectomy and bilateral adnexectomy was performed, followed ...

Waste heat recovery from exhaust gas is one of the most convenient methods to save energy in internal combustion engine-driven vehicles. This paper aims to investigate a reduction in waste heat from the exhaust gas of an internal combustion engine of a serial Diesel–electric hybrid bus by recovering part of the heat and converting it into useful power with the help of a split-flow supercritical CO2 (sCO2) recompression Brayton cycle. It can recover 17.01 kW of the total 33.47 kW of waste heat contained ...

The wind turbine blades are exposed, during functioning, to the abrasive wear generated by the impact with air-borne sand particles. In this work, samples of a commercial wind turbine blade, made of a multi-layered composite material, are subjected to abrasive wear tests, using an air streamed wearing particles test rig. Following the analysis of the tests’ results was found that the only protection against failure of the blade by abrasive damage is the surface layer. After its’ penetration, the ...
