Life on the South Side of Chambersburg Street, 1910

The people of Gettysburg, Pennsylvania heralded in the year of 1911 and reflected on their accomplishments throughout the past year. With pealing bells, tooting whistles and noisy revolvers...in a more vigorous way than has been witnessed here for many years, this New Year’s Eve celebration recognized the past year as it welcomed the new year to come. The entire town took part and its faculties were utilized in the festivities of the night, including the Court House bell and those of the St. James and College Lutheran churches...engines added their quota of noise and all over town men brought into use guns and revolvers. The year of 1910 was a noteworthy year for the town and larger county. The citizens witnessed the erection of a large number of handsome homes, a sure sign of prosperity. Business firms developed and the county saw an outstanding apple crop and tourist season. In general, the year of 1910 was proudly characterized and recorded by Gettysburg’s constituents as a great place to call home

Media Knowledge Consumers Protection

Complex and interdisciplinary researches demonstrate today, more powerful than ever, that we live in a knowledge-based society, a society in which the production, distribution and consumption of knowledge are fundamental processes. Land, labor and capital, the production factors that characterized previous societies, have been replaced in the macroeconomic indicators hierarchies by intellectual capital. Knowledge-based economy means not only the development of knowledge production and distribution, but also knowledge consumption. The new class of workers, the knowledge workers, signaled by Peter Drucker a few dcades ago, led to the development of a new class of consumers: knowledge consumers. From the wide class of knowledge consumers we will focus our attention on media knowledge consumers, respectively press and audiovisual media. The main purpose of this paper is to demonstrate the necessity of the conceptualization of this important class of consumers and to formulate a series of requirements for their protection. Having in mind the main purpose of this paper, we conducted a series of researches on two fundamental dimensions: a) the gathering of media information and knowledge from the most important newspapers and TV channels from Romania; b) the estimation of the degree of awareness of media knowledge consumers’ protection among members of the Romanian Parliament, members in change of legislating in our country. This paper presents the results of the first series of researches, on the two above mentioned dimensions.knowledge, knowledge consumers, consumers rights, media knowledge suppliers, knowledge consumers’ protection

Charles W. Peach, palaeobotany and Scotland

The move south from Wick to the city of Edinburgh in 1865, some four years after retirement from the Customs service, provided Charles W. Peach with new opportunities for fossil-collecting and scientific networking. Here he renewed and maintained his interest in natural history and made significant palaeobotanical collections from the Carboniferous of the Midland Valley of Scotland. These are distinguished by some interesting characteristics of their documentation which the following generations of fossil collectors and researchers would have done well to emulate. Many of his fossil plant specimens have not only the locality detail,but also the date, month and year of collection neatly handwritten on attached paper labels; as a result, we can follow Peach's collecting activities over a period of some 18 years or so. Comments and even illustrative sketches on the labels of some fossils give us first-hand insight into Peach's observations. Study of these collections now held in National Museums Scotland reveals a pattern of collecting heavily biased towards those localities readily accessible from the newly expanding railways which provided a relatively inexpensive and convenient means of exploring the geology of the neighbourhood of Edinburgh. Charles W. Peach had a very 'hands-on' practical approach to scientific investigation which led him to construct novel glass plates with mounted Sphenopteris cuticle, removed intact from Lower Carboniferous shales and limestones originating in West Lothian. These resemble the herbarium sheets with which he was familiar from his parallel and highly significant work on extant flora including nearshore marine algae. He also prepared hand ground glass microscope slides,particularly of permineralised plant material from Pettycur in Fife, using whatever materials he had to hand at the time. Peach's collection raises questions about the evolution of accepted standards of documentation in private collections, in parallel with the evolution of collecting practices by the new professionals such as the workers of the Geological Survey. Its relatively rapid deposition in museums,compared to many private collections, may also have contributed to its apparently high rate of usage by contemporary workers

Adolescent D-amphetamine treatment in a rodent model of ADHD: pro-cognitive effects during adolescence and cocaine abuse risk during adulthood

Attention-deficit/hyperactivity disorder (ADHD) is comorbid with cocaine abuse. Whereas initiating ADHD medication in childhood does not alter later cocaine abuse risk, initiating medication during adolescence may increase risk. Preclinical work in the Spontaneously Hypertensive Rat (SHR) model of ADHD found that adolescent methylphenidate increased cocaine self-administration in adulthood, suggesting a need to identify alternatively efficacious medications for teens with ADHD. We examined effects of adolescent d-amphetamine treatment on strategy set shifting performance during adolescence and on cocaine self-administration and reinstatement of cocaine-seeking behavior (cue reactivity) during adulthood in male SHR, Wistar- Kyoto (inbred control), and Wistar (outbred control) rats. During the set shift phase, adolescent SHR needed more trials and had a longer latency to reach criterion, made more regressive errors and trial omissions, and exhibited slower and more variable lever press reaction times. d- Amphetamine improved performance only in SHR by increasing choice accuracy and decreasing errors and latency to criterion. In adulthood, SHR self-administered more cocaine, made more cocaine-seeking responses, and took longer to extinguish lever responding than control strains. Adolescent d-amphetamine did not alter cocaine self-administration in adult rats of any strain, but reduced cocaine seeking during the first of seven reinstatement test sessions in adult SHR. These findings highlight utility of SHR in modeling cognitive dysfunction and comorbid cocaine abuse in ADHD. Unlike methylphenidate, d-amphetamine improved several aspects of flexible learning in adolescent SHR and did not increase cocaine intake or cue reactivity in adult SHR. Thus, adolescent d-amphetamine was superior to methylphenidate in this ADHD model

Algae Biofuel Triacylglyceride Transesterification Optimization

Algae biofuels may hold the key to solving the problem of fossil fuel consumption by being comparable in content, renewable, and carbon-neutral. Many biofuel researchers and corporations have undertaken to increase the production rate or capacity of triacylglycerides (TAG), the fat precursor to biodiesel fuel produced by algae, in algae cultures and published articles documenting their findings. This research is devoted to evaluating the effect of water that may be present in samples on the conversion efficiency of TAG into fatty acid methyl esters (FAME), commonly referred to as biodiesel. Therefore, that efficiency was studied to find the water content which optimizes the yield and determine if further drying of algae was necessary as an additional step in sample preparation. The results showed that the water content typically present in lyophilized algae samples is not sufficient to appreciably inhibit the reaction efficiency and necessitate extensive drying as a sample preparation step prior to transesterification
