Credibility of design rainfall estimates for drainage infrastructures : extent of disregard in Nigeria and proposed framework for practice

Rainfall intensity or depth estimates are vital input for hydrologic and hydraulic models used in designing drainage infrastructures. Unfortunately, these estimates are susceptible to different sources of uncertainties including climate change, which could have high implications on the cost and design of hydraulic structures. This study adopts a systematic literature review to ascertain the disreg

A simple screening assay for the most common JK*0 alleles revealed compound heterozygosity in Jk(a-b-) probands from Guam

The Jk(a-b-) phenotype results from alterations in the JK gene and is characterized by absence of the RBC urea transporter in the cell membrane. The frequency of Jk(a-b-) varies among populations, but this phenotype is most commonly found in people of Polynesian and Finnish descent. Although rare, Jk(a-b-) individuals present a clinical challenge because anti-Jk3 is produced readily in response to

Respiratory heme A-containing oxidases originated in the ancestors of iron-oxidizing bacteria

Respiration is a major trait shaping the biology of many environments. Cytochrome oxidase containing heme A (COX) is a common terminal oxidase in aerobic bacteria and is the only one in mammalian mitochondria. The synthesis of heme A is catalyzed by heme A synthase (CtaA/Cox15), an enzyme that most likely coevolved with COX. The evolutionary origin of COX in bacteria has remained unknown. Using ex

A matter of timing: system requirements for repair and their temporal dimensions

Research into repair within the circular economy (CE) typically focuses on technical aspects of design, policy, and markets, and often assumes or implies simplified conditions for the user/owner and the product-system to explain the barriers to scaling repair activities. By integrating life cycle and temporal dimensions (time-sequence) into a broad System of Repairability framework, we demonstrate

Sex ratios at birth in Australia according to mother's country of birth : A national study of all 5 614 847 reported live births 1997-2016

OBJECTIVES: Son preference and sex selective practices have resulted in a deficit of girls in several countries, primarily across Asia. Emerging evidence indicates that son preference survives migration to Western high-income countries. The objective of this study was to assess male-to-female (M/F) ratios at birth per mother's country of birth in Australia 1997-2016, in total and by parity, and by

The Role of Patents and Licensing in the Governance of Human Genome Editing: A White Paper

On 12 July 2021 the World Health Organization (WHO) Expert Advisory Committee on Developing Global Standards for Governance and Oversight of Human Genome Editing published a set of reports entitled Human Genome Editing: A Framework for Governance and Recommendations. These reports provide valuable advice and recommendations on appropriate institutional, national and global governance mechanisms fo

Dispersal and spatiotemporal distribution of Protapion fulvipes in white clover fields : implications for pest management

Yield loss caused by insect pests remains a substantial problem in agriculture. Chemical control, with potential negative effects on non-target organisms, is still the main tool for pest management. For pest species with limited dispersal capacity, rotation of the crop in time and space has potential as an alternative management measure. This is particularly important in organic farming, where mos

Metabolic factors and the risk of Dupuytren’s disease : data from 30,000 individuals followed for over 20 years

Dupuytren’s disease (DD) is a fibroproliferative disorder affecting the palmar fascia of the hand. Risk factors include diabetes mellitus (DM), whereas a high body mass index (BMI) is associated with a lower prevalence of DD. The aim of this study was to further elucidate risk and protective factors for the development of DD using longitudinal population-based data from the Malmö Diet and Cancer S

Intravenous Vitamin K1 for the Correction of Prolonged Prothrombin Times in Non-Bleeding Critically Ill Patients: A Prospective Observational Study

The aim of this study was to evaluate the effects of vitamin K1 on various vitamin K-dependent proteins in critically ill patients with prolonged Owren PT. We included critically ill non-bleeding adult patients without liver failure or anticoagulation treatment, with Owren PT > 1.2, who were prescribed intravenous vitamin K1. Blood was drawn at baseline and at 20–28 h after vitamin K1 administratiThe aim of this study was to evaluate the effects of vitamin K1 on various vitamin K-dependent proteins in critically ill patients with prolonged Owren PT.

Emissions of soot, PAHs, ultrafine particles, NOx, and other health relevant compounds from stressed burning of candles in indoor air

Burning candles release a variety of pollutants to indoor air, some of which are of concern for human health. We studied emissions of particles and gases from the stressed burning of five types of pillar candles with different wax and wick compositions. The stressed burning was introduced by controlled fluctuating air velocities in a 21.6 m3 laboratory chamber. The aerosol physicochemical properti

An Analysis of (Sub-)Hourly Rainfall in Convection-Permitting Climate Simulations Over Southern Sweden From a User’s Perspective

To date, the assessment of hydrological climate change impacts, not least on pluvial flooding, has been severely limited by i) the insufficient spatial resolution of regional climate models (RCMs) as well as ii) the simplified description of key processes, e.g., convective rainfall generation. Therefore, expectations have been high on the recent generation of high-resolution convection-permitting

Next generation relay autotuners—analysis and implementation

In order to produce models for automatic controller tuning, this paper proposes a method that combines a short experiment with a novel scheme for approximating processes using low-order time-delayed models. The method produces models aimed to tune PI and PID controllers, but they could also be used for other model-dependent controllers like MPC. The proposed method has been evaluated in simulation

All the cells of the individuals with phenotypes "p" y "Pk" lack the glucidic antigens of "public" blood groups. These subjects form natural and regular antibodies against the missing structures (anti-P, anti-PP1 y anti-PP1Pk) that agglutínate or hemolyze the red-blood cells of every individual, excepting those with the same phenotype. Due to the exceptional character of these pictures (a few indi

Comparing Reproductive Health Awareness, Nutrition, and Hygiene among Early and Late Adolescents from Marginalized Populations of India: A Community-Based Cross-Sectional Survey

Adolescence (10–19 years) is marked by many physiological changes and is vulnerable to health and nutritional problems. Adolescence, particularly, early adolescence is inadequately addressed in our national surveys. The present study aimed to assess the reproductive health awareness, nutrition, and hygiene of marginalized adolescent girls and boys and compare them among early and late adolescents.

YtkA (CtaK) and YozB (CtaM) function in the biogenesis of cytochrome c oxidase in Bacillus subtilis

Cytochrome c oxidase in the respiratory chain of bacteria and mitochondria couples the reduction of molecular oxygen to form water with the generation of a transmembrane proton gradient. Bacillus subtilis has two heme A-containing heme–copper oxidases: the menaquinol oxidase cytochrome aa3 and the cytochrome c oxidase cytochrome caa3. By screening three collections of mutants for defective cytochr
