A discourse on human hair fibers and reflections on the conservation of drug molecules

1996

A gross discourse on human hair fibers and their formation is presented stressing the various interdisciplinary aspects, such as the morphological, biological, structural and biochemical data considered to be important in the field of hair analysis. An attempt is made to explain the incorporation of drug molecules during hair fiber formation by using the classical concepts of drug absorption based on lipoid theory and the pH-partition hypothesis as well as a modern biological approach on the permeability of cell membranes. In addition to the physiochemical considerations of the transport properties of a particular drug molecule such as a) the lipophilicity, which determines permeability thr…

Corporate social irresponsibility: What we know and what we need to know

2022

Corporate social irresponsibility (CSI) is a critical issue for managers and researchers. In fact, the number of studies on this subject from diverse literature is rapidly increasing, seeking to answer questions regarding the core elements of CSI, its antecedents, and consequences. This paper offers a comprehensive literature review of this topic, identifying and assessing previous studies, synthesizing their findings, and highlighting knowledge gaps. Additionally, it offers recommendations regarding how to move forward. Our review identified 155 studies published from 1962 to 2020 that describe the antecedents, outcomes, mediators, and moderators of CSI according to different levels of ana…

Monitoring and data quality assessment of the ATLAS liquid argon calorimeter

2014

The liquid argon calorimeter is a key component of the ATLAS detector installed at the CERN Large Hadron Collider. The primary purpose of this calorimeter is the measurement of electron and photon kinematic properties. It also provides a crucial input for measuring jets and missing transverse momentum. An advanced data monitoring procedure was designed to quickly identify issues that would affect detector performance and ensure that only the best quality data are used for physics analysis. This article presents the validation procedure developed during the 2011 and 2012 LHC data-taking periods, in which more than 98% of the proton-proton luminosity recorded by ATLAS at a centre-of-mass ener…

Appropriate technology in a Solovian nonlinear growth model

2007

We propose a Solovian growth model with a convex-concave production function and international technological spillovers. We test the empirical implications of the model, analysing the effects of the productivity slowdown that followed the oil shocks of the 1970s. We argue that this slowdown, altering the world income distribution, affected the pattern of international technological spillovers, taking the poorest countries further away from the technological leaders, and therefore unable to exploit their technologies. The result is the emergence of a poverty trap for low-income countries.

La Sindrome Compartimentale Addominale (ACS) dopo chirurgia dell'Aneurisma dell'Aorta Addominale (AAA)

2009

Introduction: The Abdominal Compartment Syndrome (ACS) is a “condition in which increased tissue pressure in a confined anatomic space, causes decreased blood flow leading to ischaemia and dysfunction and may lead to permanent impairment of function” Materials and Methods: between june 2007 and june 2008 we treated surgically 23 cases of AAA (14 in election and 9 in emergency), with indirect intra-abdominal pressure (IAP) monitoring (intra-vescical catheter). Mean age was 68 (64-84) years. Mean transverse diameter was 6,2 cm (min 5,5 e max 9,0). Rise in IAP more then 20 mmHg was considered for surgical decompression. In 1 case we registered preoperatively IAP more than 20 mmHg treated with …

Building sustainable contextual ambidexterity through routines: a case study from information technology firms

2020

The purpose of this paper is to explain the role that routines play in achieving sustainable organisational ambidexterity in information technology (IT) firms. Our exploratory analysis of four case studies reveals the key importance of routines in setting the context for sustainable ambidexterity. Companies build up contextual ambidexterity through routines derived from normalization of processes, normalization of skills, and normalization of results. The findings of the study show that routines support IT professionals to decide whether to exploit or explore in each particular case. Firstly, the enabling character of explicit routines as a result of the normalisation of work processes and …

Monitoring Risk Factors and Improving Adherence to Therapy in Patients With Chronic Kidney Disease (Smit-CKD Project): Pilot Observational Study

2022

Background Chronic kidney disease is a major public health issue, with about 13% of the general adult population and 30% of the elderly affected. Patients in the last stage of this disease have an almost uniquely high risk of death and cardiovascular events, with reduced adherence to therapy representing an additional risk factor for cardiovascular morbidity and mortality. Considering the increased penetration of mobile phones, a mobile app could educate patients to autonomously monitor cardiorenal risk factors. Objective With this background in mind, we developed an integrated system of a server and app with the aim of improving self-monitoring of cardiovascular and renal risk factors and…

Rapid Quantification of Microalgae Growth with Hyperspectral Camera and Vegetation Indices

2021

Spectral cameras are traditionally used in remote sensing of microalgae, but increasingly also in laboratory-scale applications, to study and monitor algae biomass in cultures. Practical and cost-efficient protocols for collecting and analyzing hyperspectral data are currently needed. The purpose of this study was to test a commercial, easy-to-use hyperspectral camera to monitor the growth of different algae strains in liquid samples. Indices calculated from wavebands from transmission imaging were compared against algae abundance and wet biomass obtained from an electronic cell counter, chlorophyll a concentration, and chlorophyll fluorescence. A ratio of selected wavebands containing near…
