Heterosis of body weights and egg weights of f1 snails (archachatina marginat...Alexander Decker
This study evaluated heterosis (hybrid vigor) of body weights and egg weights in three mating groups of Archachatina marginata snails - a black-skinned x black-skinned group, a white-skinned x white-skinned group, and a black-skinned x white-skinned crossbred group. All groups showed positive heterosis for body weight at hatching and in juvenile stages up to 4 weeks, with the crossbred group showing significantly higher values. Similarly, all groups showed positive heterosis for egg weight, with the crossbred group having a significantly higher value of 60.77%. The results suggest that heterosis can be exploited to improve snail growth and reproductive traits through selective breeding

This document discusses criteria for developing higher learning institute modules that promote problem solving skills. It outlines 6 criteria for curriculum development identified in the literature: 1) using real-world problems as learning contexts, 2) involving students in three phases of learning - focusing, finding out, and reflecting, 3) allowing recursion where students apply and extend their learning, 4) using graphic organizers, 5) emphasizing metacognition, and 6) supporting collaboration. The document argues module design in Ethiopian universities should focus on depth over coverage and developing lifelong learning abilities through problem-based approaches.
This document provides guidance on fire safety design for schools in England and Wales. It summarizes the regulatory background and requirements, and outlines general design principles for fire safety, including risk assessment and the selection of appropriate fire protection systems. The document then provides detailed design guidance for ensuring adequate means of escape, limiting internal fire spread, restricting external fire spread, and providing appropriate access for fire services. It is intended to help designers meet the life safety and property protection requirements of national building regulations.

Eduardo Silva is an open source engineer at Treasure Data who works on Fluentd and FluentBit projects. FluentBit is a lightweight log collector for embedded Linux applications and IoT devices. It has built-in system metrics collection and supports custom inputs and outputs using msgpack serialization. FluentBit integrates with Fluentd for log aggregation and is designed to have low resource usage for constrained environments. The roadmap includes adding a library mode and more supported sensors.
