THE Mercedes‐Benz Model DB‐601A aero‐engine is a development of the Daimler‐Benz Aktiengesellschaft of Stuttgart, Germany, a firm which lias been engaged in the manufacture of automotive and aero‐engines for over fifty years. During the first World War the Daimler Motorcn Gesellschaft of Stuttgart produced the famous Mercedes aero‐engines iii three 6‐cylindcr types with ratings of 160 horse‐power, 180 horse‐power, and 260 horse‐power. Equally renowned were the 160 horse‐power and 230 horse‐power 6‐cylindcr aero‐engines built by Benz and Company in Mannheim. After the war, and as a result of the economic and financial crisis which brought almost complete stagnation to the automotive industry in Germany during the early twenties, these two companies were practically forced to combine their activities in order to survive. Accordingly in 1926 a merger was consummated between the Daimler and Benz organizations. Thus came into being the firm of Daimler‐Benz A.G. and their product, the Mercedes‐Benz line of automotive vehicles and aircraft power plants.

In Fig. 29 are plotted the data obtained during a dynamometer calibration of the DB‐601A engine. The family of curves on the left hand side of the figure gives the sea level power characteristics for various r.p.m. in the operating range, plotted against absolute manifold pressure in inches of mercury. From these curves it will be noted that the automatic boost control takes charge to restrict the manifold pressure to a limiting value of 39 in. of mercury absolute at engine speeds above 1,900 r.p.m. Below 1,900 r.p.m. the full throttle manifold pressure is less than the boost limit established by the automatic regulator. The normal rating of the engine at 2,400 r.p.m. is thus established at 995 horsepower. For take‐off the automatic regulator is overruled by the pilot's throttle for a time interval of one minute established by an automatic clock mechanism, to produce an excess boost in the manifold which, at an engine speed of 2,500 r.p.m., gives the take‐off rating of 1,150 horse‐power at 43·2 in. of mercury absolute manifold pressure. The take‐off power at 2,500 r.p.m. versus absolute manifold pressure characteristics are shown at the upper left hand portion of Fig. 29. The sea level power ratings are somewhat flexible since it is possible to adjust the oil How into the fluid coupling of the supercharger and, by changing the slip, vary the effective impeller ratio. Thus it may be desirable for bomber installations involving take‐off with heavy loads to increase the effective impeller ratio for the maximum boost possible with the quality of fuel available.
The management of children′s literature is a search for value and suitability. Effective policies in library and educational work are based firmly on knowledge of materials, and on the bibliographical and critical frame within which the materials appear and might best be selected. Boundaries, like those between quality and popular books, and between children′s and adult materials, present important challenges for selection, and implicit in this process are professional acumen and judgement. Yet also there are attitudes and systems of values, which can powerfully influence selection on grounds of morality and good taste. To guard against undue subjectivity, the knowledge frame should acknowledge the relevance of social and experiential context for all reading materials, how readers think as well as how they read, and what explicit and implicit agendas the authors have. The good professional takes all these factors on board.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

Purpose: Lesbian, gay, and bisexual (LGB) young adults smoke at rates much higher than the general population. Young adults, in general, are less likely to seek medical help for smoking cessation and LGB individuals are less likely to seek health care generally. Alternative methods to encourage smoking cessation are necessary. This research seeks to establish whether LGB young adults in California would be willing to use social media for smoking cessation.
Approach: We conducted 41 qualitative interviews among LGB young adults in the San Francisco Bay Area and Los Angeles in Fall 2014.
Findings: The results suggest that our participants were interested in a LGB-focused social media intervention, as long as the intervention was private or anonymous and moderated. Further, across topical areas our participants spoke extensively about the import of social connections. We may be able to leverage these connections to encourage cessation.
Research Limitations: This is a qualitative, non-generalizable dataset from a fairly limited geographic area.
Public Health Implications: Online smoking cessation interventions aimed at young adults would benefit from further testing with LGB young adults to ensure efficacy among this population. In addition, states and localities concerned about young adult LGB smoking might benefit from investing in an online socially mediated cessation forum. Online interventions could be scalable and might be useful for other groups who regularly face discrimination, stigma, or other stressors that make successful smoking cessation difficult.

Within the past few years, responsible educators, librarians, parents, counselors, social workers, therapists, and religious groups of all sexual persuasions and lifestyles have recognized the need for readily available reading material for lesbian and gay youth. Unfortunately, this material is often buried, because it is embedded in larger works. To meet this need, I have compiled and annotated 100 of the best works for young homosexuals, bisexuals, and heterosexuals. I have also included a few of the best works currently available on heterosexuality as a much needed source of knowledge for all young adults whether they are gay or straight, whether they remain childless or eventually become parents.

African American male teachers are increasingly becoming an endangered species among the profession of education in the public, private, and higher sectors. Working with African American males at a predominately white institution (PWI), these students are often overlooked and overburdened with outliving stereotypes that are expected of them via the media montage that has been presented by mainstream America. Fortunately, these men often arise and surpass the status quo and become what W.E.B. DuBois surmises as the talented tenth. In a candid interview with the two African American males, out of the 1,200 students who are in the teacher education program at this PWI, the students talk explicitly on how to recruit and retain African American males, like themselves, through examples, mentors, and role models that will affect the decision of future male teachers and cultivate the African American male teachers who are currently in the program. Using a qualitative research design, the students will answer several hypotheses that will allow one a closer look into the world of young African American male teacher perspectives in the PWI.
