From concept to certification; interview with AD&C co-founder and CEO Marcus Basien
Before any aircraft concept takes to the sky, air travel authorities require the aircraft be certified. One would expect a big organisation like EASA would function like a centralised verification authority. However, small companies like Aircraft Design & Certification Ltd. offer certification services for general aviation aircraft. Leonardo Times sat down with AD&C co-founder Marcus Basien to discuss the process of certification, future developments of the industry and possibilities for Aerospace Engineering students.Aerospace Engineerin

Chemical characteristics of Delaware River water, Trenton, N.J., to Marcus Hook, PA.
This progress report gives the results of an investigation of the quality of water in the Delaware River from Trenton, N. J. to Marcus Hook, Pa., for the period August 1949 to December 1952. The Delaware River is the principal source of water for the many industries and municipal water supplies along this reach of the river and both industries and municipalities use it for the disposal of their wastes. Consequently, a study of the quality of the water and variations in the quality caused by changes in streamflow, tidal effects, pollution and other factors is important to the many users. In both New Jersey and Pennsylvania steps are being taken to abate pollution, thus it is of more than passing interest to measure the effects of waste treatment on the quality of the Delaware River water.
At average or higher rates of streamflow the mineral content of the water increases slightly from Trenton to Marcus Hook. There is little variation in the concentration of dissolved minerals from bank to bank or from top to bottom of the river. At times of protracted low rates of flow the effect of ocean water mixing with the river water may be noted as far upstream as Philadelphia. At such times the salinity is often greater near the bottom of the river than near the top. The increase in chloride concentration upstream from Philadelphia is small compared to the rapid increase downstream from Philadelphia. Temperatures of offshore water vary with the season, but on a given day are substantially uniform throughout the reach of the river from Trenton to Marcus Hook.
The water contains less dissolved oxygen as it flows downstream indicating that oxygen is being consumed by oxidizable matter. From Philadelphia downstream there are periods, especially in late summer, when the dissolved oxygen is barely sufficient to meet the oxygen demands of the pollution load.Geological Survey Water-Supply Paper 126

Nygulgus evelinae Marcus 1954
Nygulgus evelinae Marcus 1954 Figures 6, 8 E. Material and locality. S pecimens in vivo studied by squash method. Twelve specimens sectioned in the sagittal plane, MLP 5365, 5366, Punta Piedras (28 00, 12 2 01, 24 8 01; 4 4 02; 5 3 03). Comments. Live adult specimens were 480 µm long and 95–115 µm wide, and fixed specimens were 200 µm long. Marcus (1954) mentioned that the largest specimens were 500 µm long and 200 µm wide, which represents a slightly larger size compared to the specimens studied here. The epithelium of the Río de la Plata specimens was 4 µm thick, with a well developed basal membrane and very numerous small rhabdites. The first two features are coincident with Marcus´description (Marcus 1954); however, this author mentioned the absence of rhabdites in the epithelium. The parenchyma of live specimens contains symbiotic algae, greenish brown in color. Marcus (1954) mentioned that the distribution of the symbionts in the parenchyma is variable; however in the studied material the algae were concentrated on the dorsum, from the pharynx to the posterior body.The brain is large, almost the same size as the pharynx. The eyes are located in the anterior region, with large pigment granules arranged around three visual cells (Figure 6 C), in agreement with Marcus´description. The mouth is subterminal, with a sphincter. The buccal tube has ciliated epithelium surrounded by muscles, expanded to form the pharyngeal bursa. The pharynx was 80 µm long and 40 µm wide in live Brazilian specimens (Marcus 1954), while the pharynx of Argentine specimens is 44 µm long. In the same work, this author mentioned that the pharyngeal nuclei are located in the oesophagus, while the nuclei observed in the pharynx correspond to the pharyngeal glands and myoblasts. The pharynx presents a triradiate lumen, continued into the intestine. The latter bears a crown of “Minot’s gland cells” at its cephalic end. The male reproductive system consists of two lateral testes located in posterior half of body (figure 6 B); in contrast, Marcus (1954) mentioned that the testes are at pharynx level. One efferent duct issues from the caudal end of each testis, connecting with the seminal vesicle posterior to the pharynx. The ejaculatory duct crosses over the penis papilla, which is wrapped by a thin trumpetshaped sclerotic stylet. The base of the stylet is formed by two rings; it is 38 µm long and 16 µm wide at the level of these rings, and 7.5 µm wide at its expanded distal end (figure 6 A). The stylet illustrated by Marcus (1954) is slighted shorter than the ones studied here (approximately 30 µm long and 12 µm wide proximally, after Marcus 1954, figure 35). The stylet reaches the male region of the atrium rostrally. The atrium opens to the exterior through a midventral gonopore, surrounded by a sphincter. The morphology of the female reproductive system agrees with the original description (Marcus 1954), comprising a pair of ovaries located near the caudal body, and partially covered by two dorsal vitellaria. The germinative region of the ovaries has rostroventral position, and the ovocites become mature towards the caudodorsal region. The oocytes are arranged biserially in the germination zone, and uniserially at mature stage. Two short ovovitelloducts open into the female region of atrium. The proximal atrium functions as uterus. Spermatozoids were frequently observed in both uterus and bursa; these structures are separated by a sphincter. The bursa is thin in young specimens and communicates with the intestine; this connection disappears in adults. The bursa functions as bursa resorbiens and the uterus acts as seminal receptacle (Marcus 1954). A gland, sometimes lobulate, with eosinophilic secretions, opens on the ventrocaudal wall of the uterus. Previously known distribution. Brazil: mangrove swamp at the estuary of Itanhaen River (50 km southwest from Santos) (Marcus 1954). This is the first record of this species in Argentina, as well as the first citation after its original description.Published as part of Brusa, Francisco, Damborenea, Cristina & Noreña, Carolina, 2008, " Dalyellioida " (Platyhelminthes, Rhabdocoela) from the Río de la Plata estuary in Argentina, with the description of two new species of Gieysztoria, pp. 1-16 in Zootaxa 1861 on pages 12-13, DOI: 10.5281/zenodo.18366

Male Blues Lyrics 1920-1965: A Corpus Assisted Analysis
This study is a corpus assisted investigation into blues lyrics. Using Wmatrix, an online statistical analysis tool, 795 different blues songs from 35 different male blues artists have been analysed quantitatively for information pertaining to key domains, words and parts of speech. This data has provided the basis for further, qualitative analysis of lyrics with reference being made to ideas already established in other studies of the blues and to linguistic theories about narrative, discourse and metaphor. The thesis seeks to define the linguistic features of blues lyrics at different historical points and attempts to interpret them in the light of the social and political conditions of their times. In doing so, it examines the role of blues lyrics within the African-American community as a whole and investigates the extent to which they established a sense of black identity and were part of a linguistic sub-culture. Further to the exploration of the genre as a whole, the dissertation includes a study into the work of an individual artist, Robert Johnson, with the aim of testing the extent to which he is representative of the blues form in general
