Integrated Firefighting Helmet

KEYWORDS

OBJECTIVE
The object of this paper is to ascertain the safety standards of the firefighting helmets. Specifically, this paper attempts to determine if there are any upper limits to the weight of the helmets. The research will be directed to determine if there is any optimal distribution recommended for the mass of the firefighting helmets. The fabrication process will be examined which support such standards which are recommended for the safety and security of firefighting personnel.

Research Questions

Precisely, this research is conducted to determine the strengths of the firefighting helmets and the impact Continue reading...

Introduction

Laryngeal cancer is cancer of the larynx (voice box, vocal cords, or other areas of the throat. Laryngeal carcinoma is the second most common malignancy of the neck and head and the eleventh most common form of cancer among men over the world (Chu and Kim, 2008). The larynx is responsible for the respiration, phonation, and deglutition while it also contributes to smell and taste by allowing the air to move over the special sense organs. Therefore, loss of laryngeal function directly affects swallowing and speech (Chu and Kim, 2008).
In 2011, there were more than 89,000 people Continue reading...

Currently, oropharyngeal cancer, or the cancer of oral and pharyngeal cavity grouped together is considered to be the 6th most common type of cancer worldwide (Warnakulasuriya 309; Saman 1). Annually, there is an estimated 650,000 new cases of head and neck cancer with 275,000 cases of oral cancer while pharyngeal cancer accounts for another 130,000 (Warnakulasuriya 309; Herrington 3). It is also reported that in such number of patients actually diagnosed as having oropharyngeal cancer, 350,000 actually die from it although survival rate is relatively higher (Herrington 3; Warnakulasuriya 313). In total, 90% of oropharyngeal Continue reading...

Introduction

Millions of firefighters are facing head and neck injuries due to the weight of fire-helmets. These helmets are the rescue helmets that are a part of their protective clothing. This research will focus on the main three issues:
1) Any upper limit of the weight that can be safely supported by the head with regards to both short- and long-term injury?
2. Is there an optimal distribution of mass that would minimize the risk of head and neck injury?
3. Are different design criteria, in terms of loads and load distributions, required for helmets intended for women?
Many studies Continue reading...

Artemisia Gentileschi’s painting titled Judith Beheading Holofernes was known to be one of the most brutal and intense illustrations of the scene. At first glance, the masterpiece of Artemisia can be considered filled with cynicism. For a lot of people who saw the painting, the image is interpreted as a sort of payback for an evil done.

Jamison, in her essay titled In Defense of Saccharin, she claims that people are easily enthused by basic surfaces of Continue reading...

Abstract:

The total hip replacements are indispensable medical procedures that address the hip problems of people. The medical practice for some time has been an adequate solution for hip problems. However, problems has been discovered that the materials used for the implants that are composed of metals and alloys cause fretting corrosion which leads to various health complications and implant failure. This paper discusses the hip joint implants and the fretting corrosion that complicates the medical practice. It touches the adverse effects of the implant corrosion in the health of the patients. Furthermore, this paper divulges some of the design Continue reading...

First of all, you need to determine what constitutes a broom. Broom and consists of a base of flexible rods, which are attached to the base. Broom can be wood or plastic, with plastic or natural bristles. Since the purpose of this assignment is to find a method of recycling plastic waste, we will make a plastic broom with plastic bristles (Recycle, 2015).
As a basis for the broom, you can choose any old shoe brush, floor brush or just a piece of wood with holes in it. The length, width and thickness of this wooden bar are chosen Continue reading...

These disorders affected me physically, mentally, and emotionally. They affected my ability to excel in school. I was enrolled in a Special Education school to help me with the sensory issues, writing problems, and medication management. My progress of each academic year, grades 3 through 7, was Continue reading...

Individuals with physical disabilities display a very wide and incredibly varied range of impairments that affect their function in a myriad of ways. While many specific motor impairments are associated with certain disabilities, most with physical disabilities are unique in the extent, severity, and nature of their motor impairments. One child or adult with cerebral palsy may present with completely different motor impairments than another child with the same diagnosis.
When working with individuals with disabilities, in order to understand the person’s physical functioning it is important to understand the characteristics of motor impairments. It can be difficult Continue reading...

Abstract

HPV-associated cancers are caused by HPV, which is a non-enveloped double stranded DNA virus that is ubiquitous in nature. It attacks the squamous epithelial cells present in the mucous membranes of the body. The virus manifests itself as benign warts or as malignant cancers. Some of the cancers caused by HPV are HPV-associated squamous cell cancer of the head and neck (HNSCC), cervical intraepithelial neoplasia (CIN), penile intraepithelial neoplasia (PIN), anal intraepithelial neoplasia (AIN) and oropharyngeal cancer. HPV+ HNSCC is the sixth most common cancer in the world. Cervical cancer is the second most common cancer in women and Continue reading...
