BACKGROUND: Parrots are one of the most frequently kept and bred bird orders in captivity.This increases poaching and thus the potential importance of captive populations for rescue programmes managed by zoos and related institutions.Both captive breeding and poaching are selective and may be Pants influenced by the attractiveness of particular spe
The coral reef area at Karimunjawa National Park is decreasing over time.There are two factors causing damage to coral reefs, namely natural factors and anthropogenic factors.The purpose of this study was to determine Pants the anthropogenic threats that cause damage to coral reefs at Karimunjawa National Park and any protection efforts to maintain
The problem of cooperative interception of the manoeuvring target is investigated in this paper.Firstly, in light of fast fixed-time consensus theory, time-to-go, and undirected topologies, adaptive cooperative guidance along the line-of-sight (LOS) direction is proposed to guarantee impact time synchronization.Next, novel nonsingular Pyjamas termi
The life-long supply of blood cells depends on the long-term function of hematopoietic stem cells (HSCs).HSCs are functionally defined by their multi-potency and self-renewal capacity.Because of their self-renewal capacity, HSCs were thought to have indefinite lifespans.However, there is increasing evidence that genetically identical HSCs differ in
Processes of research evaluation are coming under increasing scrutiny, with detractors arguing that they have adverse effects on research quality, and that they support a research culture of competition to the detriment of collaboration.Based on three personal perspectives, we consider how current systems of research evaluation lock early career re
