Introduction Neural tube defects (NTDs) are severe birth defects of the central nervous system and refers to failed neural tube closure during embryonic development (Ghi et al., 2018). The phenotype presented by those with NTDs is dependent on where the neural tube remains open (Copp and Greene, 2010). Therefore, the seriousness of disease manifestation varies. … Read more

Otherwise classified as MDMA or ecstasy, Methylenedioxymethamphetamine is a psychomotor stimulant that is synthetically derived from the structure of amphetamines. MDMA is a chiral molecule, meaning that it exists in two forms, which are labeled as S(+) MDMA and R(-) MDMA. S(+) MDMA is thought to possess greater central pharmacological effects. The attachment of the … Read more

Rock art is an indicator of occupation of land, and the presence of intelligence and culture within human societies. It offers us a cognitive insight into early modern humans where archaeology is often obstructed from the psychological. Dating rock art, therefore, is of incredibly high importance so that we are able to attribute the works … Read more

The role of an archaeologist is to uncover the truths about past civilisations. When an artefact is discovered, they must piece together how it fits into history; where it is found, when it was made, what it was used for. In this essay, I will be investigating the various ways in which physical methods are … Read more

Cesium is a lethal chemical that is used in industrial/energy/healthcare industries and it is important to know how to handle/maintain/dispose of it. The first discovery of cesium was in 1860 by a man named Fustov Kirchhoff. It has a silvery gold color and is soft and ductile. Its atomic number is 55 and there are … Read more

Summary The aim of this study was to characterize in detail 25 sour cherry cultivars and provide data on their industrial processing into high-quality cloudy juices (ScCJ). Anthocyanin composition was identified and quantified by LC-PDA-MS. Kinetic degradation (k x103, t1/2, D value) and color (CIE La*b*) were measured before and after six months of storage … Read more

Introduction In botany, the radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination. The radicle is the embryonic root of the plant, and grows downward in the soil (the shoot emerges from the plumule). With today’s ever increasing global population, maintaining an … Read more

1. Emphasizes on the setting up of an effective framework, which encourages transparency and an inclusive approach for all member nations to share research and development, contribute to space technology development and share benefits from the ultimate colonization of Mars: a. UN with its members will develop working groups to take into account the contributions … Read more

Rice cultivation believed to be developed in the dry zone over many years ago and now it has been distributed in all agro-ecological regions except at very high elevation. According to water availability, three major categories are been recognized as major irrigation schemes (41%), minor irrigation schemes (25%), and rainfed rice lands (34%) (Bambaradeniya et … Read more

The aim of this research to deduce the different outcomes of the usage of typical aquaponic low EC-high pH conditions compared to high EC-low pH conditions on crop growth, yield and crop quality in an ebb-and-flood system. Introduction In a growing population, more food is being in demand. Thus, more productive ways of producing food … Read more

As scientists and archeologists have discovered, prehistoric humans have evolved into stronger, more advanced versions of the genus Homo in which we see today. One of the most distinct adaptations of the human is the enlargement of the brain, as well as advancements in specific areas of the brain, which have lead to increased intelligence … Read more

There are more than 8 million species on the planet and with such large numbers, there is a need to accurately identify them in a way that is universal for scientists across the world to understand. The scientific process of classifying organisms (both living and extinct) is known as taxonomy. In the past, basic processes … Read more

Here, we want to study the underlying mechanism that causes the increased yield caused by an interaction between P. arrhenomanes, and M. graminicola in rice roots.
