Records of the War of the Rebellion include copies of naval correspondence (reports, letters, telegrams, and general orders) from both the Union and Confederate Navies discussing their operations. According to the introduction in the first volume, the first series "embraces the reports, orders, and correspondence, both Union and Confederate, relating to all naval operations on the Atlantic and Gulf coasts and inland waters of the United States during the war of the rebellion, together with the operations of vessels acting singly, either as cruisers or privateers, in different parts of the world. These reports are accompanied by such diagrams and maps as may be necessary" (pp. ix-x). Index starts on page 847.

AbstractTwo-compartment electrodialytic extraction (2C-ED) is a one-step process for the simultaneous phosphorous extraction and separation of heavy metals from sewage sludge ash (SSA). The process is driven by an applied electric DC field, which can be supplied from renewable sources. The proof-of-concept of the method was conducted in small laboratory cells; however, upscaling to a continuous 2C-ED process, which additionally can treat SSA suspensions at a low liquid-to-solid (L:S) ratio, requires a new design. This paper presents such a new design. In principle, ED consists of two compartments separated by a cation exchange membrane. One compartment contains a suspension of SSA in water and the anode. A cathode is placed in the other compartment. Electrolysis at the anode acidifies the suspension causing the dissolution of phosphorous and heavy metals. The heavy metals are separated from the suspension by electromigration into the catholyte, whereas the dissolved phosphorous remains in the dispersion solution. In the new design, the SSA was suspended in a tube-shaped reactor with the cation exchange membrane covering the outside. The reactor was placed in a container with the catholyte. Periodically turning off the reactor kept SSA in suspension even at a low L:S ratio without corners and pockets where the SSA otherwise tends to settle. Five 2C-ED experiments were conducted with 1.5 to 3 kg SSA at varying currents and durations. Up to 89% P was extracted. The extracted P was concentrated in the dispersion solution of the SSA suspension, where the obtained P-related concentrations of heavy metals were far below the limiting values for spreading on agricultural land. The experiments underlined that treating the SSA in a suspension with a low L:S ratio is advantageous. A comparison to previous laboratory experiments in small cells treating 50 g SSA shows a significantly more efficient use of the applied current in the new reactor setup. Thus, the new reactor design for 2C-ED fulfilled the set criteria for the operation and did additionally result in a higher efficiency than the laboratory setups, i.e., the design can be the first step towards an upscaling.

Citologicamente, as espécies de Passiflora com número cromossômico conhecido podem ser divididas em três grupos: 2n=12, 24, 36; 2n=18, 72 e 2n=20. O número cromossômico básico proposto para o gênero é x=6, sendo x=9 e x=10 considerados números básicos secundários. Por outro lado, Passiflora apresenta uma variação no conteúdo de DNA nuclear entre o maior e o menor genoma conhecidos de cerca de 10x, com valores 1C variando de 0,212 pg em P. organensis a 2,68 pg em P. quadrangularis, o que representa um alto grau de diversidade intragenérica. No presente trabalho relata-se o padrão de bandas CMA3/DAPI, a distribuição dos sítios de DNAr 45S e o conteúdo de DNA (2C) em espécies e híbridos interespecíficos de Passiflora do grupo com x=9. Preparações citológicas foram submetidas à análise convencional, dupla coloração com os fluorocromos CMA3/DAPI e FISH utilizando sonda de DNAr 45S e 5S. O conteúdo de DNA foi estimado por citometria de fluxo. Os resultados mostraram 2n=18 cromossomos para as espécies e híbridos interespecíficos analisados e dois ou três pares de sítios de DNAr 45S, estando esses últimos co-localizados com as bandas CMA3+/DAPI-. Os valores 2C estimados foram 3,45 ± 0,03 pg em P. edulis, 3,59 ± 0,09 pg em P. laurifolia, e 2,60 ± 0,06 pg em P. lutzelburgii. Nos híbridos, foi observado 2C = 3,86 ± 0,08 pg para P. laurifolia x P. edulis e 3,24 ± 0,05 pg para P. laurifolia x P. luetzelburgii, valores 10% e 5%, respectivamente, maiores que o esperado. Este é o primeiro registro de contagem cromossômica, caracterização citogenética e de conteúdo de DNA para a espécie P. luetzelburgii, cujos dados mostraram os menores valores para o comprimento dos cromossomos, corroborado pelo menor valor 2C entre as espécies com 2n=18. O número e a posição terminal das bandas heterocromáticas e sítios de DNAr 45S mostraram-se bastante conservadas, sendo a origem híbrida suportada cariologicamente mediante relação com os parentais.

This research examines the role of the mass media in young people's disengagement from politics. In a nationally representative telephone survey ( N = 1,501), young people (ages 14 to 22) reported their habits for 12 different uses of mass media as well as awareness of current national politics and time spent in civic activities. Following Putnam's hypothesis about the beneficial effects of civic ties on political involvement, the authors predict and find that civic activity is positively associated with political awareness. Contrary to Putnam, they find that media use, whether information or entertainment oriented, facilitates civic engagement, whereas news media are especially effective in promoting political awareness. Although heavy use of media interferes with both political and civic engagement, the overall effect of media use is favorable for each outcome. The results are discussed in regard to the potentially greater use of the media to build community engagement in young people.

Although the Act was already promulgated in 2007 it is still not active. Certain definitions of the Act seemed to be very controversial; especially the role of the supernatural in healing that could be associated with witchcraft and criminal-related behaviour. Aims: The aim is to determine if the Witchcraft Suppression Act (Act No 3, 1957) is discriminatory against the traditional healer as well as well as to determine if the Traditional Health Practitioners Act (No 22, 2007) and the traditional healer are contravening the regulations of Act No 3 (1957). Methods: The exploratory and descriptive method was used to evaluate and to reproduce any research data. This method offered information to compare the two acts in their functioning with each other. Results: From the data extracted from various sources it seems as if Act No 22 (2007) was promulgated without in-depth research on the role that the traditional healer may play in witchcraft activities. The aim of Act No 3 (1957) was totally ignored. Conclusions: Act No 3 (1957) does not discriminate against Act No 22 (2007). Instead, it seems that various stipulations of Act No 3 have been transgressed by the traditional healers without legal action being taken against them.
