Microwave Hybrid Sintering may extend the service life of dental ceramics

ABSTRACT: INTRODUCTION: Dental Ceramics are required to withstand a complex environment with several mechanical and chemical challenges. Testing the mechanical properties of the material can provide a good insight of the compatibility of the material for dental function. However, due to the particular failure mode of ceramics, fatigue tests are more reliable to predict the … Read more

Gender is a social construct

The concept of gender is as old as humans. George Orwell once stated “all animals are equal, but some are more equal than others” (Eriksen, 2015). The act of gendering is exertion of power, instilling your dominance or submission onto another. Anthropology is the scientific study of humanity, while the study of gender examines the … Read more

Food preservation

Throughout the history of mankind science has searched into the realms of the unknown. Along with it bringing new discoveries, allowing for our lives to become healthier, more efficient, safer, and at the same time, possibly more dangerous. Among the forces driving scientists into these many experiments, is the desire to preserve the one fuel … Read more

Effectiveness of physics teaching module (esp. uncertainty in measurements)

I. INTRODUCTION Physics, being inherently an experimental science, involves direct observation and physical experimentation. The undergraduate laboratory is thus an essential part of any physics course, developing practical, computational and experimental skills, and certain habits in novice physicists, training them to ‘think like a physicist’ over the course of their degree. The University of Durham … Read more

The stages of protein synthesis from DNA

A gene is a segment of DNA which is used for an amino acid sequence which then creates polypeptides. Protein is synthesised through a process in which the DNA is decoded and then the amino acids are then generated from this. This is called gene expression. There are some components needed in order for DNA … Read more

Qualitative research is a method among many others of how we describe and explain our social world, … Read more

Phosphofructokinase Structure and Function

Phosphofructokinase (PFK) is an enzyme of glycolysis which occurs at a critical point, regulating pathways within the third step of the process. PFK catalyzes the conversion of fructose-6-phosphate (F6P) to fructose-1,6-biphosphate (F1,6BP) by adding a phosphate from ATP, thus creating ADP. The enzyme is sustained allosterically and the △ºG (-14.2 kj/mol) of the reaction is … Read more

Identification of unknown bacteria

Identification of unknown bacteria is a critical part of microbiology. The purpose of the experiment is for students to learn different characteristics of bacteria, construct a proper dichotomous key, carry out tests to differentiate and narrow down bacteria, and use the results to identify two unknown bacteria. By carrying out this experiment, students learn how … Read more

Adding tomato and asparagus powders in processed cheese

Abstract: Rheological, chemical and sensory properties of processed cheese fortified with different levels of tomato (1%, 2% and 4% wt/wt) and asparagus (0.5%, 1% and 1.5% wt/wt) powders were analyzed. Both of the powders decreased the pH and lipolysis indexes and increased proteolysis extent of processed cheese. Phenolic and lycopene content and antioxidant activity decreased … Read more

Cyanobacteria

A synthesized BiVO4/TiO2 nanocomposite by hydrothermal method was employed for the removal of MC-LR. Response surface methodology (RSM) was applied to assess the effects of operating variables (pH, contact time, and catalyst dose) on the MC-LR removal. The coefficient of determination (R2) was calculated 98.7% for the response. The obtained maximum MC-LR removal efficiency was … Read more

Molecular clouds

Abstract Molecular clouds are dark, cold, dense regions of high extinction within the ISM. They confine the majority of the mass in the ISM and these clouds are the primary sites of star formation within the galaxy.
