Measurements of the production cross sections of prompt D0, D+, D∗+, D+s, Λ+c, and Ξ+c charm hadrons at midrapidity in proton−proton collisions at s√=13 TeV with the ALICE detector are presented. The D-meson cross sections as a function of transverse momentum (pT) are provided with improved precision and granularity. The ratios of pT-differential meson production cross sections based on this publication and on measurements at different rapidity and collision energy provide a constraint on gluon parton distribution functions at low values of Bjorken-x (10−5−10−4). The measurements of Λ+c (Ξ+c) baryon production extend the measured pT intervals down to pT=0(3)~GeV/c. These measurements are used to determine the charm-quark fragmentation fractions and the cc¯¯ production cross section at midrapidity (|y|<0.5) based on the sum of the cross sections of the weakly-decaying ground-state charm hadrons D0, D+, D+s, Λ+c, Ξ0c and, for the first time, Ξ+c, and of the strongly-decaying J/psi mesons. The first measurements of Ξ+c and Σ0,++c fragmentation fractions at midrapidity are also reported. A significantly larger fraction of charm quarks hadronising to baryons is found compared to e+e− and ep collisions. The cc¯¯ production cross section at midrapidity is found to be at the upper bound of state-of-the-art perturbative QCD calculations.
Thomas Bowrey, who was an employee of the British colonial government, visited the Malay-speaking region at the end of the 17th century and published a dictionary of Malay (1701) which consists of 12,683 headwords. It is one of the oldest and largest collections of data on this language, which was the first language of the people he came into contact with while travelling through the Malay Peninsula, spending most of his time in harbours along its west coast. Malay, which was spoken in the various trading centres of this area (e.g. Penang, Malacca), had long previously begun to develop into a form of lingua franca during Bowrey’s stay there due to the fact that traders, especially those from Arabic countries (beginning in the 12th century), China (from the 15th century onwards), Portugal (since 1511), the Netherlands (since 1641), and less so from England, came into contact with Malays speaking their local dialects in the various trading posts in Malaya and probably began to become acquainted with the trade-language variant. Thus, Bowrey must have observed and recorded elements of both.
The data he collected is not limited to Malay variants spoken in coastal areas, but includes material from dialects which he encountered during his travels throughout the Malay Peninsula, though without, however, describing the locations in which he took notes on the lexicon and clauses. Not all of his material was written into manuscript form during his stay in Southeast Asia. A large part of his notes taken in situ were prepared for publication during his long journey home. His notes, which were used to print his dictionary, are in part kept in British libraries. Most of the material accessible to the public was studied during the preparation of this thesis.
Earlier works on this dictionary are quite limited in scope. They deal with very specific aspects such as the meanings of headwords found between the letters A and C (Rahim Aman, 1997 & 1998), and the work of Nor Azizah, who deals with the lexical change found in Bowrey’s dictionary between D and F, and syntactic and sociolinguistic aspects (Mashudi Kader, 2009), and collective nouns by Tarmizi Hasrah (2010). This study will discuss Bowrey’s dictionary as a whole in order to describe its contribution to our knowledge of linguistic and non-linguistic facts in 17th century Malaya. Besides analysing Malay synchronically, this thesis also deals with historical-comparative questions and asks whether Bowrey contributes to our knowledge of the changes to the Malay language between the 17th and 21st centuries.
In order to answer the research questions, this study not only relies on the dictionary in its entirety, but also on the notes found in British libraries as well as other material on early Malay, such as the Pigafetta list (1523), Houtman (1598–1603), and the Wilkinson dictionary (1901) as a complement to Bowrey’s dictionary; at the same time, the Malay Concordance Project (online), the SEAlang Project (online), Kamus Besar Bahasa Indonesia (online), and Kamus Dewan Edisi Keempat (2007) will represent modern Malay. It should be borne in mind that in contrast to the Thomas Bowrey dictionary (TBD), Kamus Dewan Edisi Keempat (KDE4) does not hold information on colloquial forms of Malay, many of which reflect features of lingua franca Malay. This study is divided into two different branches, namely the consideration of synchronic aspects and historical comparative aspects.
Finally, this study concludes that the Malay language in Thomas Bowrey’s dictionary is heavily influenced by both external and internal factors prevalent to the 17th century. The Malay language recorded in the Thomas Bowrey dictionary is very similar to modern Malay. The similarities between the Malay language of the 17th century and the Malay language of today are considerable, even though there are, of course, still some notable variances.
Graphium chironides malayanum Eliot, 1982 was described as a taxon occurring sympatrically with G. bathycles bathycloides in Peninsular Malaysia. However, the validity of the subspecies has been questioned in a recent publication that was based on a study of DNA and morphology, implying that G. c. malayanum is a synonym of G. b. bathycloides and G. chironides is absent from the Peninsula. A re-examination of male wing morphology, genitalia and DNA shows that G. c. malayanum is a valid taxon distinguished from G. b. bathycloides by wider discal markings, a less falcate forewing, distinct differences in the arms of the harpe in the male genitalia and clearly divergent mtDNA COI genes. In the DNA analysis, G. c. malayanum formed a monophyletic clade closely related to G. chironides from China, and both were well-separated from the G. b. bathycloides clade. An examination of characters used in the previous study showed that the conclusions reached were due to misinterpretation of diagnostic characters, misidentification of specimens and the absence of G. c. malayanum among the specimens examined. When these characters were correctly interpreted, each specimen was readily assigned to the correct taxon. Diagnostic morphological characters are reclarified based on the current data.
Two new species of terrestrial isopods are described from iron ore caves in Brazil, within the Amazon biome, Circoniscus mendesi López-Orozco, Campos-Filho & Bichuette sp. nov. and C. xikrin López-Orozco, Campos-Filho & Carpio-Díaz sp. nov. (Scleropactidae). In addition, the knowledge of the distribution of Ctenorillo ferrarai Campos-Filho, Araujo & Taiti, 2014 (Armadillidae) is extended to Parauapebas, and Benthanoides tarzan Cardoso & Ferreira, 2023 to south area of the Campos Ferruginosos National Park, both in the State of Pará. Moreover, a distribution map and photographs of the species are given.
Three new species of Loxosceles Heinecken & Lowe, 1832 (Araneae, Sicariidae) from Brazilian caves
(2024)
Three new species of recluse spiders are described from Brazilian caves with both males and females. Loxosceles boqueirao Bertani & Gallão sp. nov. is found in the State of Bahia, in the Serra do Ramalho karst area, it belongs to the rufescens species group, and is closely related to L. cardosoi Bertani, von Schimonsky & Gallão, 2018 and L. carinhanha Bertani, von Schimonsky & Gallão, 2018 from the same karst area. Thus, there are now three species in the Serra do Ramalho karst area closely related, but noticeably distinct morphologically from other species of Loxosceles. Loxosceles planetaria Bertani & Gallão sp. nov. and L. bodoquena Bertani & Gallão sp. nov. are found in the State of Mato Grosso do Sul, in the Serra da Bodoquena karst area. They belong to the gaucho species group and are closely related to L. gaucho Gertsch, 1967. These are the first species of Loxosceles described from this karst area in the State of Mato Grosso do Sul. Loxosceles boqueirao sp. nov. and L. bodoquena sp. nov. bear some troglomorphisms and are, herein, proposed as troglobitic species, whereas L. planetaria sp. nov. is proposed as a troglophilic species. Brazil has now 22 described species of Loxosceles.
The remarkable sharpshooter Prodigiella silvanoi gen. et sp. nov. is described and illustrated (including the external form, color, male and female terminalia) from the Atlantic Forest of southern and southeastern Brazil (states of Paraná and Rio de Janeiro). The new genus can be distinguished from other Neotropical genera of the Cicadellini by a combination of various morphological features, including an asymmetrical aedeagus with a bifid shaft and peculiar basal and apical processes and ovipositor valvula II distinctly expanded beyond basal curvature, its dorsal margin with 35–40 teeth, and ventral margin without preapical prominence. A discussion comparing Prodigiella with superficially similar taxa of the genera Macugonalia Young, 1977, Ruppeliana Young, 1977, and Versigonalia Young, 1977 is provided. The discovery of this peculiar new genus indicates that much collecting work in the remaining parts of the Atlantic Forest is clearly and urgently needed.
