This article aims to describe the relationship between donors and their recipients in the context of organ transplants. This analysis is made in the light of Marcel Mauss’s work, offering an expansion on an analysis of his discussion on the “spirit of the gift” and his idea that gifts require reciprocation. It is argued that some recipients of donated organs receive a personal element from the donor in that there is a transfer or sharing of the donors’ personality and spiritual qualities. The article examines the n [...]

This paper proposes a Wind Turbine Emulator (WTE) using an Indirect Field Oriented (IFO) Induction Motor (IM). The IM drive can be controlled as a conventional prime mover in speed mode, or a wind turbine in torque-speed mode via robust observed torque control. This paper presents key issues for establishing a high-performance IFO IM drive. Further, this study develops a wind turbine load Interior Permanent-Magnet Synchronous Generator (IPMSG) followed by a three-phase Vienna Switch-Mode Rectifier (SMR). It receive [...]

Mixed ligand copper(II) complexes of the empirical formula [Cu (L)(TFAA)]X, where L represents 2,2´-bipyridine (Bipy), 1,10´-phenanthroline (Phen), or 4,7-diphenyl-1,10´- phenanthroline (Dphen), TFAA is 1,1,1-Trifluoro-2,4-pentanedione, and X is the counter ion (BF4- or ClO4-), were synthesized and characterized by spectroscopic, magnetic, molar conductance, elemental, and thermal analysis. Solvatochromic studies revealed that all the complexes showed bathochromic shifts. A square planar geometric structure is prop [...]

The production of concrete using recycled aggregates, obtained from the processing of construction and demolition waste, is extensively practiced worldwide. However, the effect of simultaneous adding fine recycled aggregate and the recycled coarse aggregate on the mechanical properties of concrete is still unfamiliar. This work aims to evaluate the influence of the water/cement ratio (WC Ratio), the fine recycled aggregate content (%FRA), the coarse recycled aggregate content (%CRA), as well as the interaction betw [...]

Background: The present study evaluates the effects of selective directed forgetting (SDF) and directed forgetting (DF) on subsequent memory retrieval and investigate whether acute exercise can facilitate the effects of SDF. Methods: A four-arm (n=20 per group; N=80; Mage=20 yrs), parallel-group, randomized controlled experiment was employed. The four groups included: 1) exercise plus SDF (Ex+SDF), 2) SDF only (SDF), 3) DF only (DF) and 4) R (remember) only (R). Participants viewed two separate word lists (list 1 a [...]

Toxoplasmosis in liver transplantation (LT) is uncommon, especially in the current era of universal prophylaxis with trimethoprim-sulfamethoxazole (TMP-SMX) for Pneumocystis jirovecii pneumonia (PJP). Here we present a case of a 55-year-old woman LT recipient, on dapsone or PJP prophylaxis due to sulfa allergy, who presented on day 25 after LT with fever, diarrhea and abdominal pain. Initially she was diagnosed with cytomegalovirus-associated colitis and was treated with intravenous ganciclovir, with good clinical [...]

One of the crucial steps in the enzymatic hydrolysis of biomass is pretreatment. We investigated the applicability of a hybrid pretreatment method, This involved acid treatment followed by alkali before the production of fermentable sugars from cassava stem. The substrate was initially treated with acid (1% oxalic acid at 100 °C for 2 h), followed by treatment with a 10% NaOH–urea mixture (by mixing 5 g each of NaOH and urea in 100 mL of water) at 100 °C for 1 h. A cellulose recovery of 98.55% was obtained with the [...]

Objective: The present study aimed to elucidate the relationship between oral exercise and oral function among older adults requiring care in the nursing facilities of Japan. Methodology: The subjects were adults aged 65 years or above, requiring care and admitted to the nursing facilities for older adults in Japan. The subjects performed the assigned oral exercises, which included the exercises focused on the neck, shoulder, upper limbs, tongue, lips, cheek movement, vocalization, and deep breathing, in groups und [...]

Fluorescence In-Situ hybridization (FISH) is a sensitive and highly efficient technique commonly used in routine diagnostics. Most of these tests that use analyte-specific reagents are not approved by US Food and Drug Administration (FDA) but are developed by individual test laboratories. There is an emerging demand for prenatal diagnosis of aneuploidies by FISH. Since most of these assays are laboratory-developed tests, it is essential to validate them prior to their use in diagnosis. However, validation procedure [...]

Skin regeneration is a multidisciplinary topic that involves plastic surgery, aesthetics, and dermatology. In the last few years, several molecules have been used to prevent or delay the skin aging process. Recently, promising investigations on novel β-1,3/1,6-glucan-based treatments, associated with sodium hyaluronate, have demonstrated the induction of a naïve biological stimulus in soft tissues. Serum Revitalizing Face (Lot 00118a0051 of 11/19/2018 approved by the Italian Ministry of Health as a Medical Device-C [...]
