Bothynus araya Duarte & Grossi 2020, new species
No full textBothynus araya Duarte & Grossi, new species (Figs. 5 A–F; 7B; 8E; 9E; 10D, F; 12E) Diagnosis. Both sexes of B. araya are similar to B. entellus; however B. araya can be distinguished using the following characters: stridulatory apparatus with well-marked carinae near to basal margin in both sexes (Fig. 7B); parameres with lateral “flaps” distinctly as narrow as basal half (Fig. 8E); female differ from the females of other species in this group by the pronotum with weakly punctate concavity and smooth discal area (Fig. 10D) and proventrite with a long furrow at anterolateral angles (Fig. 10F). Etymology. The specific epithet is named as tribute to the grandmother of the first author. The name “araya” originates from the Tupi-Guarani dialect, meaning “grandmother”. This name should be treated as a noun in apposition. Type material. Holotype not dissected. Brasil: Paraná: Guarapuava, 3.IV.2012, Oliveira. G.B. – 1♂ (CERPE). Paratypes [16 males and 2 females].

Concentration in Knowledge Output: A case of Economics Journals
No full textThis paper assesses the degree of author concentration in seven economics journals, which were published in India during 1990-2002. To measure the degree of author concentration, Lotka's Law was used. Moreover, we also make an exploratory analysis of the geographic, economics subfield and institutional concentration in 704 economics journals. An important finding of this paper is that specialized journals in the sample report the highest degree of author concentration. This result is quite similar to the findings by Cox and Chung (1991). Furthermore, there are several instances showing that the journals lean towards certain norms; this may affect the flow of innovative ideas into economics. We conclude that a knowledge activity, involving the high degree of concentration and a biased publication process, may affect the flow of new ideas into the discipline.Concentration, Lotka's Law

Survey Report - Casey Station, Antarctica, 1985 - by G.B. Lawrence
No full textProgress Code: completedStatement: See the survey report for more details.Survey report for Casey Station, 1985, by wintering technical officer G.B. Lawrence.<br/><br/>Taken from the survey report:<br/><br/>Projected Summer Program<br/>It is proposed to accurately survey the bedrock in the Dome summit region as preparatory work for future ice drilling. Ice thickness will be measured by ground based ice radar and contouring carried out by barometric heighting.<br/>The testing of a newly designed electro-mechanical drill will also be incorporated into this survey.<br/>A survey of raised beaches of the Windmill Islands is planned as well as a preliminary aerial survey of marine exposures near Jacks Donga.<br/><br/>Projected Traverse Program<br/>It is projected to carry out four glaciological traverses during 1985.<br/>The major objective is the re-measurement of ice movement stations along the previously established eastern line at 69 degrees south as well as snow accumulation measurements,gravity and surface observations and a comprehensive drilling program for stratigraphy studies. This is to occur mainly during the spring traverse. AN ice radar survey is to be undertaken on the eastern line as well as on the return journey along the planned parallel offset approximately 50 kilometres north.<br/>A secondary objective, but of highest priority for winter, is the establishment of a new line to the east of Law Dome and, time permitting, the re-measurement and possible extension of the GW line to the south-west.<br/>During the autumn traverse, generally a "shake-down", the aim is to depot fuel on the eastern line in preparation for the spring traverse and a new line parallel to and to the north of GD03 - GD01 is to be surveyed which would entail emplacement of five new ice movement stations. These stations are to be re-measured in spring

Towards labonachip optical trapping and Raman spectroscopy of extracellular vesicles using multiwaveguide traps
No full textOptofluidic lab-on-a-chips (LOCs) employing a dual-waveguide trap for optical trapping and Raman spectroscopy have proven to be attractive and potent tools for high throughput chemical fingerprinting of bio-particles for disease diagnosis. Among the relevant bio-particles are extracellular vesicles (EVs) which a been proven through recent studies to be potential biomarkers for identification of diseases, such as cancer. However, EVs are small with diameters ranging between 30 and 1000 nm and present a challenge for both on-chip optical trapping and Raman Spectroscopy. The research presented in this thesis is aimed at the development of a multi-waveguide optical trap aimed at the combined on-chip optical trapping and Raman spectroscopy for biochemical characterisation of single EVs.Firstly, the capabilities and limitations of a dual-waveguide trap for stable on-chip optical trapping of EVs is investigated through an in-depth simulation study. This ultimately yields a comprehensive overview of stable trapping conditions for EVs in terms of EV diameter and refractive index, and the injected optical power. Then, novel multi-waveguide traps are designed and fabricated. These multi-waveguide traps lead to stronger light confinement in the channel, resulting in improved optical trapping and Raman signal generation. This is experimentally demonstrated through the optical trap stiffness values and the recorded Raman signal strength of polystyrene beads generated between a 2-waveguide and 16-waveguide trap. Finally, the 16-waveguide trap is used to demonstrate optical trapping of B. Subtillis spores, as an intermediate step towards EVs. Optical trapping of the spores is studied with both experiments and simulations. Special attention is paid to the effect of random phase differences between the beams exiting the waveguides on the optical trap quality.In conclusion, the results show promising prospects for the realisation of multi-waveguide traps for on-chip biochemical fingerprinting of EVs with optical trapping and Raman spectroscopy. <br/
A denaturing of the non- places: The redefinition of the urban voids of the escalator area in Hong Kong
No full textThe city produces spaces that could be termed as voids, due to a momentum of a design which tends to fill with clear functions and meanings each corner of it. As the city develops, within the limits of it appear as an integral part, spaces that lack of a clear role. Their meaning is continuously open to the formulation and often emerges "randomly" from the event of occasional events. What may make the acceptance of the void as a key element in an urban structure and under what conditions this (urban space) can be determined? The absence of a building in an area of the city is not enough for giving him the concept of 'urban void'. Spaces that can be characterized by a specific function or they serve an aesthetic point of view, and particularly in any case characterized by contents of the "filled" with interesting or indifferent actions of everyday life within cannot be defined as urban voids. Instead it could be seen to what extent, and even buildings are urban voids in conditions devoid of above characteristics. The voids are derivatives of unforeseeable transformations of the city. Their presence creates strange feelings. It could be seen as a reaction to the body of the city or a collateral development. So, which is the aesthetic perception of the urban voids of the escalator area? What defines them as voids? They are places? Or non- places? Do they have potentials to be filled with a specific function and which is the best solution? To be an integral part of the city or a parasitical formation of spaces? The site of the escalators is a mosaic of non-places, a mixture of different micro worlds with an escalator system to penetrate them and automatically define them as a performance. People who travel with the escalators are the viewers of the performance. Those who use the micro worlds, the performers, experience the semi-private spaces. But what exactly is the role of public space in this area? How can we re-define the new Hong Kongian public space under the new conditions of neo-liberalism? Which is the part of these urban voids inside this interrogation and redefinition of the public space? In conclusion, how we should treat these urban voids in order to serve the new re-defined feeling of Hong Kong? Goal The purpose of this project is to re- question and to re- defines the urban feeling of the Hong Kong through the re- formation of the urban voids of the escalators- area.dsd. architecture thinkingArchitectureArchitectur
