The Subject

I will describe in this paper some features of current Boeing-Vertol production helicopters that I have selected as those which strike me personally as being of particular engineering interest. But first just to provide some perspective on the subject I would like to summarise the background of the present Vertol Division of The Boeing Company. The Company was formed in 1944 as the Piasecki Aircraft Corporation and its first product was the HRP Tandem Rotor Helicopter, which first flew in 1945. This was followed by the HUP in 1948, the H-21 in 1952 and the H-16 in 1953. In 1956 the Company was renamed Vertol and the next aircraft to fly was the Model 107 Prototype in 1958. In 1960 Vertol was acquired by Boeing and became the Vertol Division. The currently manufactured models about which I am going to talk, are the 107 series (now mostly in production as the US Marine Corps Model CH-46, Sea Knight) and the 114 series (in service with the US Army as the CH-47, Chinook) of helicopters.

State Of Research

The article deals with the problems associated with Polish immigrants who served in the US Army during the armed conflict in Cuba in 1898. Due to the current state of research, we can only roughly estimate the number of Poles involved in the Spanish-American war. A variety of articles concerning the subject appeared in the contemporary Polish press, based on which attempts were made to outline the general circumstances behind Polish recruitment into the US Army as well as other issues related to, inter alia, military careers, military pastoral care and collective memory of the war.

Available Information

In recent years, the US Army began actively looking for a replacement for the 5.56 mm M16/M4 assault rifle, which currently is the standard issue weapon for the infantry. The US Army has selected three potential companies to produce the next generation assault weapon. These are the following companies Sig Sauer, General Dynamics, and Textron systems. All companies have submitted prototypes for the next generation assault rifle that are the subject of the analysis in this paper. In addition, the companies also offer new types of ammunition for the abovementioned systems. The purpose of this paper is to compare the three assault rifle prototypes and the ammunition they use to highlight their potential strengths and weaknesses and to address possible reliability problems. Although many of the specifications of the weapons are the subject to company secret, the paper will provide a comparative analysis of small arms samples that plan to replace the 5.56 mm M16/M4 assault rifle, according to available information from various sources.

Background: Insult to the brain, whether from trauma or other etiologies, can have a devastating effect on an individual. Symptoms can be many and varied, depending on the location and extent of damage. This presentation can be a challenge to the optometrist charged with treating the sequelae of this event as multiple functional components of the visual system can be affected. Case Report: This paper describes the diagnosis and subsequent ophthalmic management of an acquired brain injury in a 22 year old male on active duty in the US Army. After developing acute neurological symptoms, the patient was diagnosed with a pilocytic astrocytoma of the cerebellum. Emergent neurosurgery to treat the neoplasm resulted in iatrogenic cranial nerve palsies and a hemispheric syndrome. Over the next 18 months, he was managed by a series of providers, including a strabismus surgeon, until presenting to our clinic. Lenses, prism, and in-office and out-of-office neurooptometric rehabilitation therapy were utilized to improve his functioning and make progress towards his goals. Conclusions: Pilocytic astrocytomas are the most common primary brain tumors, and the vast majority are benign with excellent surgical prognosis. Although the most common site is the cerebellum, the visual pathway is also frequently affected. If the eye or visual system is affected, optometrists have the ability to drastically improve quality of life with neuro-optometric rehabilitation.
