History is the past analyzed and recorded, it is not everything that ever happened or everything that historians have already written about. While the existence of subjectivity in history is not often questioned many philosophers have rejected the possibility of objective historical knowledge. This essay seeks to explain the ways in which history consists of both elements of objectivity and subjectivity. Objectivity refer to the lack of bias. With this being said there is no objective truth…

1.1 Overview
 CSF definition It is a well-known fact that the brain lies within the skull and the spinal cord lies within the vertebral column. Between the soft neutral tissues and the bones that house them are three types of membranous coverings called meninges. Some of the space between these coverings is called subarachnoid space and filled with clear and colorless fluid (cerebrospinal fluid “CSF”). CSF circulates inside the central nervous system through the ventricular part of this system…

Prostate cancer is the second leading cause of cancer death amongst men in the United States. One in six men is estimated to be diagnosed with prostate cancer at some point in their lives. Similar trends are found worldwide to mirror those of the United States. However, the progression of prostate cancer is typically slow and does not metastasize all that often. Due to this, treatments can typically be life saving and prostate cancer deaths have declined ~35% from 1997 to 2007. This can…

Using robots in the workforce is becoming more and more popular. They are already being used in the military for jobs such as bomb detection and removal, surveillance, and even bombings. The robots in the military all have one thing in common, they are all controlled by a human. Robots which can act alone are being experimented with and in some instances being used. Robots could be used…

3A.2.10 Robustness A method is robust if it is unaffected by small changes in operating conditions. To evaluate the robustness of developed analytical method few parameters were deliberately changed. The parameters included analysis at different temperatures viz. 250C and 300C, at 0.8 and 1.0 mL/min flow rate, using C18 columns from different manufacturers one from Qualisil BDS, USA (4.6 x 250 mm x5µ) and the other from LC-GC, India (4.6 x 250mm x5µ). Each of the three selected factors were…

reference value was used for the (14C/12C)t ratio. The radiocarbon age is a fixed value and is different from the true calendar age, which can be obtained using the calibration curve that is continuously updated and extended towards the radiocarbon dating limit. Radiocarbon measurements of bone and tissue from Ötzi along with the grass found with him, were first carried out at the AMS (accelerator mass spectrometry) facilities in Zurich and Oxford. The combined uncalibrated radiocarbon age was…

Emily Oster said this “Prenatal testing is a complicated decision for many women, forcing us to confront concerns about a disabled child and risks of miscarriage.” What this tells us is any pregnant woman is susceptible to having a disabled child. In my paper. I will outline how prenatal screening is defined, the positive verses the negative outcomes, and the role of prenatal counselors. Prenatal testing is simply a set of medical tests performed on expectant mothers to determine if an unborn…

Alarm Fatigue and the Design of the Legacy Way Control Room Introduction The design of a control room is a critical aspect of ensuring the safety in many industries where data and sensors are prevalent, and having pure human monitoring is difficult or impractical. The national energy grid, petroleum refinery facilities, and railways are a few of the industries that rely on a control room to ensure the smooth and safe functioning of the system. In Brisbane Australia, the Legacy Way tunnel has a…

structure but eventually within the structure (Corbett & Brannigan, 2015). Tragic fires at the MGM Grand in 1980 and the Station Nightclub in 2003 led to more recent requirements for fire protection, including sprinkler systems, exit lighting and limits on explosives and pyrotechnics (Vaughan & Turner, 2013). Building and national fire code standards are evaluated, updated or changed every 3 years. The new changes are geared to improve life safety and fireground operations. Lesson learned from…
