This paper aims to explore the potential suitability of the press as a teaching resource for raising scientific literacy for citizenship within science education. Our methodology is based on a content analysis of a sample of 1867 articles about science and technology from four Greek newspapers. The analysis showed that the press is potentially a useful tool for teaching certain aspects of scien...

Background Biomass-derived jet fuel is an alternative jet fuel (AJF) showing promise of reducing the dependence on fossil fuel and greenhouse gas emissions. Hydroprocessed esters and fatty acids (HEFA) concept is also known as one of the pathways for producing bio jet fuel. HEFA fuel was approved by the American Society for Testing and Materials in 2011, and can be blended up to 50% with conven...

To reduce CO2 emissions in the industrial sector, high-temperature heat pumps are a key technology. This work presents an approach to design such pump system capable of supplying 200 °C sink temperature and capacity approximately 1 MW. Today’s market-available using displacement compressors not suitable for reaching that high temperatures as they need lubricating oil, which is resistant enough....

The main objective of this experimental investigation is to examine favourable machining conditions by utilising fewer resources industries for the techno-economical and ecological benefits. operations are performed in turning SS 304 using coated carbide tool inserts under dry, water-soluble cutting fluid solution form flood cooling small-quantity lubrication (SQL) employing a newly formed micr...

In present paper, I will argue that Japanese dating simulation video games can be considered as serious games. Prior to advancing my main argument, I will introduce the popular dating sim LovePlus and relate it to the historization of the concept of „techno-intimacy‟ within the Japanese society. For further contextualization of the field, I will theorize the audience at which dating sims are ai...

A number n is said to be economical if the prime power factori-sation of n can be written with no more digits than n itself. We show that under a plausible hypothesis, related to the twin prime conjecture, there are arbitrarily long sequences of consecutive economial numbers, and exhibit such a sequence of length 9.

By the time on first exploration of reservoirs and design refineries, there are many challenges appeared health, safety, environment (HSE) by conduction fossil fuels such as higher contents sulfur, nitrogen, oxygen, halogen, metals, aromatics. There side effects human health starting from simple to malignant diseases cancer. Also, safety equipement catalysts affected presence high content these...
