1. Evaluating hydraulic conductivity of soil-waste mixtures for use in sanitary landfill waterproof barriers
Resumo A incorporação de resíduos ao solo tornou-se uma solução economicamente viável e sustentável na engenharia geotécnica, uma vez que muitos rejeitos industriais quando associados a outros materiais, se demonstram capazes de sanar propriedades requeridas em projetos. Esta pesquisa objetivou formar misturas de solo incorporadas com dois tipos dife

2. A Note on the McCormick Second-Order Constraint Qualification
ABSTRACT The study of optimality conditions and constraint qualification is a key topic in nonlinear optimization. In this work, we present a reformulation of the well-known second-order constraint qualification described by McCormick in 17. This reformulation is based on the use of feasible arcs, but is independent of Lagrange multipliers. Using such a refo

3. Anesthesia or analgesia? New block for shoulder surgery: pericapsular nerve group block
Abstract Interscalene brachial plexus (ISB) block is considered the analgesic technique of choice for shoulder surgery. However, the hemidiaphragmatic paresis that may occur after the block has led to the search for an alternative to the ISB block. In this case report, the pericapsular nerve group (PENG) block was performed for both surgical anesthesia and p

4. REACTION TO ‘LINGUISTIC MEANING MEETS LINGUISTIC FORM IN ACTION’
Abstract The enactivist position adopted by Figueiredo and Cuffari is argued to represent a return to a form of behaviorism which denies that mental content is constitutive of the meaning of linguistic signs in favour of the view that language is first and foremost a physical activity based on shared practices of bodily behaviour. This view is shown to be hi

5. Effect of two oral formulations of cannabidiol on responses to emotional stimuli in healthy human volunteers: pharmaceutical vehicle matters
Objective: To compare plasma concentrations of cannabidiol (CBD) following oral administration of two formulations of the drug (powder and dissolved in oil), and to evaluate the effects of these distinct formulations on responses to emotional stimuli in healthy human volunteers. Methods: In a randomized, double-blind, placebo-controlled, parallel-group desi

7. Comparison between somatostatin analog injections
SUMMARY OBJECTIVE: Long-acting depot formulations of somatostatin analogs, i.e., octreotide and lanreotide, are the first-line medical therapies for patients with acromegaly to whom surgery/radiotherapy cannot be performed or who have inadequate response. In this study, we aimed to evaluate the short-term local and systemic adverse reactions developed after

9. Biceps tenotomy or tenodesis in association with rotator cuff repair: is there an influence on functional results? A retrospective cohort study
ABSTRACT BACKGROUND: Instability or tears of the long head of the biceps tendon (LHBT) may be present in more than 35% of rotator cuff repairs (RCR). OBJECTIVE: To compare clinical results from patients undergoing arthroscopic RCR, according to the procedure performed at the LHBT. DESIGN AND SETTING: Retrospective cohort study designed at the shoulder and

10. The Value of Spiral Chest Computed Tomography Scan in the Diagnosis of Asymptomatic Coronavirus Carriers among Paranasal Sinus and Pharynx Surgery Candidates
Abstract Introduction The nasopharynx and oropharynx are the main colonization sites of coronavirus. Therefore, patients with paranasal sinuses and pharyngeal problems (ear, nose, and throat [ENT] patients) predispose coronavirus infection. Ear, nose, and throat patients with concomitant asymptomatic coronavirus infection may develop severe pneumonia follow

11. The added value of non-contrast 3-Tesla MRI for the pre-operative localization of hyperparathyroidism
Abstract Objective: We investigated the efficacy of non-contrast 3-Tesla MR imaging added to the combination of sestamibi with99mTc (MIBI) scintigraphy and Ultrasonography (US) for the pre-operative localization of Primary Hyperparathyroidism (PHPT) lesions. Methods: A total of 34 parathyroid glands, including nine normal glands, were examined with MIBI, U

12. Prone ventilation in intubated COVID-19 patients: a systematic review and meta-analysis
Abstract Background The efficacy and safety profiles of prone ventilation among intubated Coronavirus Disease 2019 (COVID-19) patients remain unclear. The primary objective was to examine the effect of prone ventilation on the ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2/FiO2) in intubated COVID-19 patients. Methods Dat
