This research is to investigate to what extend the NIOSH-7605 and ISO-16740 methods can be used to determine insoluble hexavalent chromium in air. The methods were tested and optimized on the extraction and sample preparation steps. After optimization the methods were validation on limit of detection …

An attempt was made to develop a method for the determination of volatile organic compounds (VOCs) in air by gas chromatography mass spectrometry (GC-MS) analysis and chemical sample desorption of the 3M 3500 passive diffusion sampler. The method included a complex mixture of 205 polar and non-polar …

Small urban water bodies, like ponds or canals, are often assumed to cool their surroundings during hot periods, when water bodies remain cooler than air during daytime. However, during the night they may be warmer. Sufficient fetch is required for thermal effects to reach a height of 1–2 m, relevant …

Banana is an important commercial fruit crop for smallholder farmers in Arba Minch, southern Ethiopia. However, its sector is experiencing many constraints and limited attention given to productivity and marketing. Therefore, this study was conducted to analyze the banana value chain in order to identify …

At present, many people look the other way, stating the Corona crisis is a “wake-up call”, a disruption that paralyzes air traffic and shows us that we can still live on. Change is possible and this is very encouraging. We will overcome the coronavirus, but if the climate change and the environmental …

Airport management is regularly challenged by the task of assigning flights to existing parking positions in the most efficient way while complying with existing policies, restrictions and capacity limitations. However, such process is frequently disrupted by various events, affecting punctuality of …

Poland still has a lot of changes ahead that are necessary, especially in rural areas, if Poland wants to reach the climate goals set by the European Union. Bioenergy could be a great option for Poland as it would tackle Poland’s problems with greenhouse gas emissions, air pollution and power interruptions. …

Hundreds of sensors in our smartphones, cars, houses and other "smart" devices feed the IoT, that monitors both our functioning, and that of the smart devices. In 2050 the Internet of Things - which processes and stores all sensor data - will require a multiple of all the current energy together in air …

The creation of an unstoppable Internet of Things (IoT) is about the worst that can happen to us as humanity. Not only will the IoT soon use more energy than all our current air traffic, it will also be quite easy to create an Orwelian (1984) terror from it. In particular, the IoT is powered by sensors, …

During incubation, an embryo is developing in the egg for a period of 21 days. During the incubation process air exchange occurs between the egg and its external environment during which it loses humidity due to water diffusion through the shell. This loss in humidity can affect chicks’ quality and, …
