Mc 2015.736 Port Charcot, Booth Island (65°03.853’S, 64° 01.868’W), depth 6–16 m; collected by C. Goodwin and E. Priestley, 23/02/2015. Diagnosis. Southern Ocean Crella (Crella) with one category of lightly and evenly spined basal acanthostyles. Etymology. Named after Juliette Hennequin, first mate of the expedition vessel the Hans Hansson, in recognition of her support. External morphology. In situ appearance (Figure 7A): Bright orange crust with prominent pore sieves. Growing over bedrock. Some patches were very large (> 50 cm in diameter). Preserved appearance. Fairly firm pale yellow crust with smooth, detachable, surface on which pore sieves are clearly visible. Storage ethanol has turned orange. Skeleton (Figure 7B): Plumose. Strongly hispid ascending columns of acanthostyles and tornotes. Dense ectosomal layer of acanthoxea. Spicules: Measurements given here are from the holotype BELUM.Mc2015.725. See Table 5 for dimensions of paratypes. Acanthostyles (Figure 7C,D): 454(465)477 by 16(20) 26 µm. Slightly curved with small spines very sparsely scattered along their length, in some spicules these are so sparse that they initially appear smooth. The heads are not tylote. There is no secondary class of echinating acanthostyles. Ectosomal anisotornotes (Figure 7E): 294(325)353 by 7(11) 15 µm. Slightly fusiform tornotes with asymmetrical ends, one end usually smoothly tapered and one more abruptly pointed. Ectosomal acanthoxeas (Figure 7F): 53(62)74 by 4(7) 10 µm. Often slightly curved. Entirely spined with large spines. Remarks. These specimens are assigned to Crella as they possess an ectosomal crust of acanthoxeas and do not have chelae. As basal acanthostyles echinating the substrate are present they are assigned to Crella (Crella) (Van Soest 2002a). There are currently only five valid species of Crella (Crella) two of which, Crella (Crella) aurantiaca Bertolino, Calcinai & Pansini, 2009 and Crella (Crella) tubifex (Hentschel, 1914), have been recorded from the Antarctic. C. aurantiaca differs from our specimen in having two categories of basal acanthostyles. The form of both the categories of acanthostyles also differs in that they have very dense clumps of large recurved spines on their heads, whereas our specimen has very small spines evenly spread along the length of the shaft. Crella (Crella) tubifex possesses amphistrongyles rather than tornotes, and ectosomal acanthostrongyles rather than acanthoxeas.Published as part of Goodwin, Claire E., Berman, Jade & Hendry, Katharine R., 2019, Demosponges from the sublittoral and shallow-circalittoral (<24 m depth) Antarctic Peninsula with a description of four new species and notes on in situ identification characteristics, pp. 461-508 in Zootaxa 4658 (3) on pages 477-478, DOI: 10.11646/zootaxa.4658.3.3, http://zenodo.org/record/337602
Nephrite Jade in West Pakistan
No full textTwo pebbles of the nephrite variety of jade were found by the author in 1955 in the river bed of the Teri Toi in Kohat District of former North-West Frontier Province of West Pakistan; the positive identification of the compositions of the pebbles was, however, not made until February, 1962. This appears to be the first authenticated record of either of the true jade minerals (nephrite or jadeite) in Pakistan or India, and the discovery is of significance in relation to the unsolved problem of the origin of the raw material of Indian carved jade.</jats:p
Project Jade Weser Port: A feasibility study
No full textTogether with the amount of transported containers, the size of the container vessels increases. With the size of the ships their draught also becomes larger. At the moment Germany does not have a harbour, suitable to receive these large container vessels. The idea has risen to design and construct a new deep-water port. The authorities took some time contemplating where this port has to be built. Wilhelmshaven versus Cuxhaven was the dilemma. Finally, in March 2001, a temporary decision was made: a new deepwater port is to be built near Wilhelmshaven. One of the strongest points of the area near Wilhemshaven is the great possibilities for future expansion. The scope of this report is limited to the design of a deepwater port near the Wilhelmshaven: the Jade Weser Port. The Jade estuary is very suitable as a harbour, having a natural deep-sea channel and being situated close to open sea. Besides that, a large area is available for the terminal and the infrastructure on land has good possibilities for expansion. For a project, as great as the Jade Weser Port, several studies have to be done. The economic situation is one of the first studies that should be done. The Jade Weser Port studies into this subject are not widely available. This leads to the first question: Is the Jade Weser Port economically/financial feasible? Ballast Nedam has also done research into the future Jade Weser Port. Because of this research the design of the quay in the feasibility study gave reason to Ballast Nedam Dredging for some questions. The quay wall is not protected from waves and currents and there are no breakwaters to protect the berths. The quay lies parallel to the approach channel, just a couple of hundred meters away from it. This situation has led to the following question: Does the unprotected quay lead to any nautical or operational difficulties? If so, is there not a better option for the layout of the quay? The objective of this thesis study is to answer the questions that are outlined in the problem description above. This is done in the following studies: Financial/economical study Nautical/hydraulic study This report is a feasibility study for the Jade Weser Port. This feasibility study consists of five parts. First a study on the location and environmental aspects of the Jade Weser Port has been done, secondly a financial study has been done and after that the preliminary design aspects of the port are described. At last the currents, waves and navigation in and around the port are analysed. The feasibility study is concluded with the conclusions and recommendations for the new port. The results for the port can be presented by the following remarks: The financial feasibility study of the port does not show very encouraging results, although a definitive negative advice can not be given. The nautical feasibility study of the port does show promising results. The circumstances can be rough, but this will not result in much downtime.Hydraulic EngineeringCivil Engineering and Geoscience

In the spiky surface projections, a thick ascending fibre of principal styles (up to 20 spicules thick) cores the centre of the projection. Thinner fibres of 2–3 principal styles, heavily echinated by acanthostyles, lead up to the surface at 45° angle to the central fibre. Brushes of sub-ectosomal styles join these at the surface.

Although the species has an appearance similar to <i>C.</i> (<i>Axosuberites</i>) <i>rosita</i> Goodwin, Brewin & Brickle, 2012 this subgenus has a distinctive extra-axial skeleton and lacks echinating megascleres (Hooper, 2002b). Of the 29 species present in the Antarctic and adjacent regions only two, <i>C.</i> (<i>C.</i>) <i>lissosclera</i> Bergquist & Fromont, 1988 and <i>C.</i> (<i>C.</i>) <i>pauper</i> Brøndsted, 1927, possess two distinct categories of toxa.</p> <p> <i>Clathria lissosclera</i> can be distinguished as its megascleres are much smaller (choanosomal styles 170–190 µm and echinating acanthostyles 85–110 µm). <i>Clathria pauper</i> was originally described as having no microscleres (hence the name). Brøndsted (1927) describes basally spined acanthostyles up to 650 by 20 µm, as well as entirely spined acanthostyles up to 250 by 12 µm, and no microscleres. Hooper (1996) re-examined a fragment of the holotype (BMNH1930.11.5.2) and noted that toxas were in fact present. He gives the spicule dimensions as: principal styles with rounded smooth or microspined bases 372(606)810 by 11(15.8) 21 µm; Subectosomal styles 352(481)590 by 3(7.6) 10 µm; Echinating acanthostyles, subtylote with heavily spined base and lighter spined shaft 219(293)384 by 10(12.3) 15 µm; smaller evenly spined acanthostyles 92(148)183 by 5(8.4) 11 µm; Accolada toxas 93(139.5)185 by 0.8(0.9) 1.5 µm; wing-shaped toxas 31(45.5)52 by 1.5(1.7)2.0 µm). Our re-measurements of the type specimen agree with these. Our specimen differs from <i>C. pauper</i> in only having one category of evenly spined echinating acanthostyles, larger oxhorn toxas, and much longer principal styles.</p> <p> <b>Distribution.</b> Currently only known from the type and holotype localities.</p>Published as part of <i>Goodwin, Claire E., Berman, Jade & Hendry, Katharine R., 2019, Demosponges from the sublittoral and shallow-circalittoral (<24 m depth) Antarctic Peninsula with a description of four new species and notes on in situ identification characteristics, pp. 461-508 in Zootaxa 4658 (3)</i> on pages 487-488, DOI: 10.11646/zootaxa.4658.3.3, <a href="http://zenodo.org/record/3376028">http://zenodo.org/record/3376028</a>
Interpersonal psychotherapy for depression in Parkinson's disease
No full textStudies have shown depression to affect up to 50% of individuals diagnosed with Parkinson’s disease (PD) and to have a negative impact on the progression of the illness. However, there is a dearth of research on psychosocial interventions for the treatment of depression in this population. To date, the utility of interpersonal psychotherapy (IPT), an evidence-based treatment for depression with demonstrated effectiveness in medical populations, has not been examined for this population. This case series was conducted to examine the feasibility and effectiveness of interpersonal psychotherapy (IPT) for depression in individuals with Parkinson’s disease (PD). Three PD patients with Major Depressive Disorder or Dysthymia participated in the study along with a caregiver. Patients received 6 to 15 sessions of IPT primarily focused on resolving the interpersonal problem area of role transition. Caregivers attended 1 to 2 sessions which provided psychoeducation and garnered necessary supports to help patients accomplish their treatment goals. Two of the patients experienced improvement in depressive symptoms, particularly in mood, interest and motivation in activities, with gains maintained at 1-month follow-up. There was some evidence of reductions in caregiver burden as a result of the intervention, though no significant change in caregiver depressive symptoms was noted. Results of this case series suggest that IPT may be a feasible and effective option for the treatment of PD depression. Larger, controlled trials are needed to replicate these results and to further evaluate the efficacy of this intervention.Psy. D.Includes bibliographical referencesby Jade T. Rubin

Note: We have followed Boury-Esnault et al. 2014 who, due to molecular phylogenetic evidence, transferred the genus Caulophacus from Rossellinae to Languinellinae. They emend Tabachnick’s (2002) definition of Languninellinae as ‘ Rossellidae with strobiloplumicomes or if these are absent the concerned group(s) share so many morphological characters with a group bearing strobiloplumicomes that their common ancestry with loss of that spicule is most parsimonious…’. Type material. MNHNCL POR_ 15001. Dried sample, small sub-sample rehydrated with Decon– 90, tissue section and spicule preparation on slides. Sub-sample of above deposited as BELUM.Mc 2015.176 (spicule slide only).

Named after the research vessel Nathaniel B Palmer which in turn is named after the merchant mariner and ship builder Nathaniel Brown Palmer (8 th August 1799 – 21 st June 1877) who was amongst the first people to discover Antarctica. External appearance (Figure 5 A). Hispid cream-coloured sponge with bulbous mushroom-like top and narrow stalk. The width of the top is 25mm and height 14mm, the stalk is 4mm maximum diameter. Preserved appearance: Delicately hispid pale peach lump with firm texture and distinct but not detachable, slightly hispid, dermal surface. Skeleton. The specimen has been poorly preserved (dried then rehydrated) and skeletal structure is hard to see clearly. Confused choanosomal skeleton of diactines and non-pinnular hexactines. Hypodermal layer of pentactines and pinular hexactines with pinular ray facing outwards. Atrial layer of pinular hexactines. Microscleres are present throughout tissue. Spicules. Choanosomal diactins with rounded, slightly tylote, spined ends and a small central swelling. 903 – (1517)– 3502 by 9.3 –(18.4)– 33.8 µm (Figure 5 B). Some larger examples were also present but as these broke in both the section and spicule preparations it was not possible to measure them. Choanosomal hexactins:Tangential ray 304 –(614)– 851 µm, proximal ray 310 –(724)– 988 µm, distal ray 304 – (592)– 892 µm. Hypodermal spicules are pentactins (Figure 5 C) and hexactins (Figure 5 D) with spined tips. Proximal ray 476 – (761)– 1541 µm, tangential ray 241 –(310)– 421 µm. Pinular hexactins (Figure 5 E). Dermal pinular hexactin: Pinular ray 167 –(187)– 203 by 15.9 –(28.6)– 40.1 µm, proximal ray 69 –(77)– 87 by 7.4 –(8.5)– 11.5 µm, tangential ray 61.8 –(74.1)– 88.2 by 6.3 –(8.3)– 12 µm. Atrial pinular hexactin: Pinular ray 118 –(164)– 193 by 20.1 –(28.3)– 47.4 µm, proximal ray 33 –(73)– 98 by 5.4 –(8.6)– 12.6 µm, tangential ray 55.2 –(68.3)– 81.6 by 6.4 –(8.1)– 11.3 µm. Discohexactins (Figure 5 F). Ray length: 55 –(63)– 79 µm, total diameter 116 –(135)– 169 µm, centrum diameter 5.0–(8.3)– 11.2 µm. Diagnosis. Caulophacus is defined as a stalked fungus or cup–like Rossellidae with pinular hexactine dermalia and atrialia (Tabachnick 2002). The four sub-genera which are included in the genus are defined by the type of microscleres present: Caulophacus (Caulodiscus) Ijima, 1927 has microscleres with various terminations (discoidal, onychoidal, oxyoidal); Caulophacus (Caulophacus) Schulze, 1885 has mainly discoidal microscleres; Caulophacus (Oxydiscus) Janussen, Tabachnick & Tendal, 2004 has numerous oxyhexasters, discohexasters may also be present and Caulophacus (Caulophacella) Lendenfeld, 1915 has microscleres with exclusively oxyoidal endings. (Janussen et al. 2004). This specimen possesses only discoidal microscleres and consequently is assigned to Caulophacus (Caulophacus). There are 20 currently valid species of Caulophacus (Caulophacus) of which ten species have been recorded from the Southern Ocean and surrounding areas (Table 4). The majority of these possess discohexaster as well as discohexactin microscleres; the only species which do not are C. basispinosus Levi 1964 and C. galatheae Levi 1964. However, both of these species have oxy-tipped microscleres which are not present in our specimen.Published as part of Goodwin, Claire E., Berman, Jade, Janussen, Dorte, Göcke, Christian & Hendry, Katharine R., 2016, Hexactinellida (Porifera) from the Drake Passage (Southern Ocean) with a description of three new species, pp. 207-220 in Zootaxa 4126 (2) on pages 215-216, DOI: 10.11646/zootaxa.4126.2.2, http://zenodo.org/record/26737
Fortissat Science Alliance podcast: Conor McKinnon and Jade McMorland
No full textConor McKinnon and Jade McMorland were PhD students at the University of Strathclyde working on development of renewable energy. They took part in the Fortissat Science Alliance podcast recordings in July 2021.What is the Fortissat Science Alliance?The Fortissat Science Alliance was a Wellcome Trust & Children In Need "Curiosity" project. This scheme provided informal STEM learning opportunities for young people who attended the community centre Getting Better Together Shotts (GBT Shotts) between 2019 and 2023. Due to the COVID-19 pandemic, deliveries had to pivot online so the podcast was founded. These recordings were made via Zoom with warm-up STEM activities sent to every young person in advance, along with a profile page for each researcher, so that they were relaxed and able to ask excellent questions.Link to episode on Spotify.Depending on the broadcast date, podcast deliveries were co-sponsored by Glasgow Science Festival, EXPLORATHON 2021, or EXPLORATHON 2022/23.For the duration of the project, it was supported jointly by Children in Need and the Wellcome Trust. In 2021, EXPLORATHON episodes were supported by the European Commission [grant agreement ID 101036101]. In 2022-23, EXPLORATHON episodes were supported by the Engineering & Physical Sciences Research Council [grant number EP/X020894/1].
