Following The American Psychological Association’s Guidelines

Abstract Most buildings once completed take at least one year to settle and require repairs and maintenance. However, many older multiple dwelling buildings have suffered unforeseen issues. The most common problem is water ingress through the building envelope. The reason why residential buildings are critical and require closer and immediate attention is because these buildings belong to people who have invested their life savings into them for comfort and spend most of their time in those places. Commercial and industrial buildings do not require as much attention and their environmental separation requirements vary because they are only occupied ...

1.0 Introduction

When the concept of green building emerges, environmentalists and researchers automatically assume the solutions lie on materials and their constituencies in buildings they are part of and the lifetime of the building. Exterior material directly in contact with the environment and natural elements may enhance the sustainability of the building, but may greatly impact the functions of nearby ecosystems. Hence building sustainability and environmental maintenance are not exactly interchangeable, and yet these terms are often utilized mistakenly. The pioneers of environmental constructs are not confirmed, although architectural historians suggest they date back prior to Ancient Roman times. Architects took ...

Q1. Describe the three main layers of the Sun’s interior.

The three main layers of the Sun’s interior are the core, the radiative envelope and the connective envelope.

The core is the center of the Sun, with a density of 150 g/cc and a temperature of 15 million K. This is the region where high energy fusion reactions take place and energy is produced. The energy produced is mainly in the form neutrino and gamma rays, which are actually high energy protons which travel several light years and supply energy to the Earth and other planets. The energy produced in the core then radiates outwards through the radiative zone. The ...

Introduction

CD4 is a cellular immune response co-receptor that raises the avidity of relationship between an antigen-presenting cell and a T-cell through interaction with non-polymorphic parts of the complex between T-cell receptor and major histocompatibility class II molecules. It directly contributes to transduction of signal via cytoplasmic relationship with the lymphocyte kinase. CD4 also plays a role as the high-affinity receptor for attachment of cells as well as entrance of HIV. The CD4 extracellular part consists of domains that resemble immunoglobulin D1 to D4. This component of the CD4 has been qualified as a recombinant soluble protein, and crystal structures have been identified for ...

Severe acute respiratory syndrome is a life threatening condition that is caused by a virus from the Coronaviridae family. The SARS virus is believed to have originated from the Guangdong province of southern China before spreading to Hong Kong, Canada and the United States of America. The virus has an incubation period of 2 to 7 days but it may last up to 10 days. Like other respiratory disease, SARS is spread through direct contact; long range and short range. The major agent of transmission is the droplet nuclei. The symptoms of the disease include: fever, chills, malaise, cough, dyspnea and ...

Introduction

A supernova is coined by some astronomers as the brilliant destruction of a star, and rightfully so because of the highly complex activities that resulted to the final outburst of the of the celestial body. While the typical explanation of a star explosion is a change in its core or the excessive absorption of massive matter from another star, it took years of study for astronomers to finally present it that way. It is stimulating to note that the study of supernova dated back to ancient China, the oldest known record was shortlisted from thousands of supposed supernovae. The supernova SN 185 ...

A 1 Product defect is a serious problem. Doug told me that he had already researched the cost of fixing the defect. To calculate whether it is reasonable to fix the defect, Doug should have calculated the approximate amount of consumers, who could probably be damaged. If the sum of money to refund the damages to the customers is higher than the amount of money spent for fixing the problem, it is reasonable to present a new model for western southern regions of the country. In this case, I would provide the company with a new report that contain all the ...

Ethical Dilemma 1: Gun Rally

Ethics serves as an integral part of the justice system, including areas covering criminal law. The subject defines any discipline dealing with good and evil and with moral duty” or that which involves principles that can be defined as moral (Merriam-Webster Dictionary). One part of the definition that sounds complementing, is that ethics involves a combination of both cognition and behavioral principles. These are the basic and concrete foundation on which any form of ethics, including criminal ethics, is based. The first dilemma in this case is deeply enshrined in work ethics relating to the police force. It is ...

Performance-feedback is very important, whether it is at school or at workplace. Working for a big oil and gas company, it was that time of the year when the company’s HR would give a detailed feedback to the employees about their last one year’s performance and contribution to the company. This information and feedback was very important because it would determine the future of any employee in the organisation. It was more than a year since I had joined the company and it was my first job. Naturally, I was pretty tense about the feedback. On 02-January-2014, the company’s ...

Human Immunodeficiency Virus, a main cause of worldwide AIDs, belongs to the Lentivirus genus of Retroviridae family. Pathogen causes chronic type of symptoms, taking a long time of latency it constantly keeps replicating inside human body. HIV is categorised into two types, HIV-1 and HIV-2. The genome of this retrovirus consists of two single-stranded RNA molecules. Though, both are involved in AIDS, HIV-2 seemed less virulent and demonstrated more frequent connections with the disease of central nervous system (Fanales-Belasio et al. 5).

Felicia sat on the steps of her apartment building, bouncing a small yellow ball. It was dark out, only the dim light from the hallway behind her lighted the street. The sounds of sirens blared in the distance. A car rambled by and the thump of the loud bass vibrated through the cement of the sidewalk to where she sat. The vibration was almost soothing; she watched the car run a red light almost wistfully. It was late at night; it must be nice to somewhere to go. She happily bounced the ball a few more times before some mischievous urge ...

Introduction

Physics is an abstract field of science that influences our lives in more ways than we can imagine. From waking up every morning, to the water we drink; from driving to work, to the music we listen to; from the internet, to the cell phones that we use so often, physics governs all their basic operating principles. Many natural phenomena throw questions whose answers lie deep in physics. Why are lightning flashes so spectacular? How long does it take for light from a star to reach us? How is a rainbow formed? What causes a boomerang to swirl back? Many of these ...

Introduction

The advantage that movies have over books is that everything in the movie can tell the story: the background music, the movements or he gestures of the actors, specific unanimated scenes, dialogue, monologue and so on. On the other hands, books have only the words they are made of to tell the story and sometimes graphical indications or drawings that explain the scenes which compose the narrative. The current essay analyzes four combinations of book-film storytelling narratives (“The Natural”, “World War Z”, “Christine” and “The Hobbit”), focusing on a particular book-film combination, chosen as the worst such combination for a college-student ...

Environmental Studies

The need for a precise forecasting of the impacts of climate change on the future distribution of the Earth's principle biome is increasing. In this paper, forecasting methods covered include: the niche-theory models which categorize species by habitat (particularly environmental conditions where species may persist or perish). The general circulation models and the species-area curve models which consider large groups of species or all species. The existing climate models based on approximations of increasing carbon dioxide and, to some extent, by lessening sulfate aerosols, forecast that temperatures will rise by 2.5-10.4oF (1.4-5.8oC) between the year1990 and 2100. Greater warming ...

- Introduction Over the centuries, there has been the need to transmit secret information between a sender and a receiver. So many techniques have been developed and used in order to achieve this aim. One popular technique is cryptography; an art that encodes information as a cipher and can only be accessed by the sender or a receiver that knows the decryption code. The mere sight of coded information raises a lot of curiosity and suspicion. Anybody interested in such information may then commence efforts at deciphering the code. In order to eliminate this development, there was the need to transmit covert information ...

15 August: SEOUL, KOREA

In the burning afternoon summer air, YuKwon ran up the back stairs inside the building, his pants sticking to his drenched legs. Sweat rivered down his forehead into his eyes and steam rose from his sweltering skin, but he ignored all physical distractions, focused only on his mission. His breath even in spite of his exertion, YuKwon removed a sniper rifle from his silver metal case, loading it as he knelt at a window, being careful to remain invisible to anyone outside. His target this time was the wealthy and arrogant Choi Minhyuk, an infamous loan shark. From his window on ...

1.0 Mitochondria in eukaryotic cells Organelles are special compartments surrounded by a bilipid membrane which separates them from the rest of the cell which carry out specific functions. An example of an organelle is the mitochondria which are known to be the “powerhouse of the cell.” They have their own genome (mtDNA) and are semiautonomous. They are said to have evolved from a free α proteobacterium like organism (Takasugi, Yagi, et al., 2010). The word mitochondria is derived from two Greek words: “mitos” which means thread and “chondros” which means “grain”. These two words offer an apt description of the morphology ...

HIV VIRUS

The HIV virus is the causative agent of Human Immunodeficiency Virus (HIV). It usually infects the CD4 + T Helper cell by binding to the cell membrane, this is then followed by membrane fusion; a process that allows the virus to release viral particles into the host cell. Once infected, the T-Helper cell turns into a HIV replicating cell since the viral RNA is converted into DNA by reverse transcriptase a process facilitated by the viral proteins [ CITATION bio \l 1033 ]. The double stranded viral DNA is then transported to the nucleus where it is fused with the normal host DNA by ...
