Additional material examined: Macellicephala aciculata, holotype USNM 17405, Pacific Ocean, Southern California, Albatross station 4352, collected on 14/03/1904. Description (based on holotype and paratype). Medium sized species; holotype with 18 segments (segment 1 = tentacular segment), 13.5 mm long, 2 mm wide excluding parapodia and 5 mm wide including parapodia. Paratype (SEM specimen, on stub) with 18 segments, 13 mm long and 4.8 mm wide including parapodia. Live specimen (Fig. 13A) pink with white prostomium and pink semi-circles present at anterior margin of each prostomial lobe; preserved specimen creamy yellow in colour (Fig. 13B, C). Prostomium bi-lobed, with deep anterior notch; prostomial lobes short (not extended), anteriorly rounded (Figs. 2G and 13D, E). Frontal filaments absent. Eyes absent. Ceratophore of median antenna large, inserted in anterior notch (Fig. 13D, E, Fig. 2G); style of median antenna missing. Palps very long (extending to segment 9), slender, smooth, tapering into slender tips (Fig. 13A, B). Tentaculophores inserted laterally to prostomium, both of equal size, achaetous (Figs. 2G and 13D, E); tentacular styles missing in type specimens. Facial tubercle absent. Everted pharynx with 2 pairs of jaws and 9 pairs of small triangular papillae of equal size (Fig. 13C); each jaw with single fang and smooth margin. Nine pairs of knob-like elytrophores present on segments 2, 4, 5, 7, 9, 11, 13, 15 and 17; elytra missing in type specimens. Cirrigerous segments without dorsal tubercles; distinct dorsal cirrophores elongated, cylindrical to slightly bulbous; styles of dorsal cirri missing. Dorsal ridges appear faintly from segment 3 becoming obvious by segments 5-6, on segments 8-10 forming an oval structure, in segments anterior to segment 8 and posterior to segment 10 forming concentric structures (Fig. 13C, F). In posterior part of body only, similar ridges appear on parapodia of cirrigerous segments; first parapodial ridge lateral to dorsal ridge, second parapodial ridge near base of cirrophore. All ridges appear ciliated and white in colour under light microscope but SEM revealed no ciliation of these structures (Fig. 13F). Parapodia biramous. Notopodia greatly reduced to one stout acicula (Fig. 14A). Neuropodia large (Fig. 14A), elongated, subtriangular to rectangular in shape, with integument covered acicula protruding into slender tip; prechaetal and postchaetal lobes poorly developed. Ventral cirrus inserted basally on segment 2, where very slender and long, approaching tip of neuropodial acicula lobe; inserted medially on subsequent segments where short (much shorter than tip of neuropodial lobe) (Fig. 14A). Notochaetae nearly as stout as neurochaetae; often entirely broken off (observed on only 7 parapodia in holotype), few (about 6 per ramus observed in holotype); very long (exceeding the length of neuropodial acicular lobe) (Fig. 14A); with smooth, translucent basal half of shaft (Fig. 14C); with obvious rose-bush like alternating and interlocking spines on one side only in distal half of shaft (Fig. 14D), distal tip of notochaetae smooth and blunt (Fig. 14 E, F). Neurochaetae short to very long, numerous, translucent, of two forms: either wide and flattened with shallow denticles on both sides throughout most of their lengths (Fig. 14B) or slender, with rounded tip, with distinct rows of dense alternating denticles on both sides (few present and easily overlooked) (Fig. 14B, marked by arrow). Nephridial papillae globular, present at ventral junction of neuropodia and body on segments 10, 11 and 12, inconspicuous in other segments, present from segment 5. Reduced parapodia of segment 18 lateral to pygidium, consisting of notopodia only. Pygidium rounded. Anal cirri not observed. Additional morphological observation: Macellicephala gloveri sp. nov. was represented by 11 specimens in total. While DNA was successfully extracted from all specimens, confirming their identity, their morphological state was often rather poor. For example, the style of median antenna and dorsal cirri are missing in all available specimens. Tentacular styles are missing in type specimens but remained attached in three DNA vouchers: NHMUK.2018.9352 and NHMUK.2018.1463 (on right side only, in both specimens) and NHMUK.2018.855 (on left side only). When the tentacular cirri were observed these were smooth, very slender, both of equal length to palps. Length of palps appears to be variable as these extend to segment 9 in holotype, but are shorter (extending to segment 5) in most DNA voucher specimens, appearing shortest (extending to segment 3) in only 8 mm long DNA voucher specimen NHMUK.2018.9352. Finally, in DNA voucher specimen NHMUK.2018.855, single very small and easily overlooked elytra remained attached on segment 5 (left side only) (Fig. 8C). Elytra are translucent, with smooth margins and sparsely covered by few microtubercules when observed under light microscopy. Remarks. Semi-circular to circular dorsal and parapodial ridges described in Macellicephala gloveri sp. nov. and a closely related species from the Amundsen Sea M. linseae sp. nov., can also be also found in M. aciculata Moore, 1910. Pettibone (1976) did not re-describe this character in detail; hence a type specimen of M. aciculata (USNM #1740) was examined, although it is in a very bad condition. The neuropodia of M. aciculata are oblique, tapering into slender tip with protruding acicula medially forming prechaetal and postchatel lobes. The neuropodia of M. gloveri sp. nov. are truncated, almost rectangular, with poorly developed prechaetal and postchaetal lobes. The stout notochaetae of M. aciculata appear to possess spines on both sides but in M. gloveri sp. nov. the alternating spines are confined to one side of the notochaeta only. Based on morphological examination alone, the specimens from the Amundsen Sea were assumed to belong to one species. Subsequent molecular work [see Brasier et al. (2016)] revealed the presence of two distinct clades, suggesting presence of two species. Upon closer re-examination, some chaetal differences were observed in representatives of the two clades leading to erection of a second species as Macellicepala linseae sp. nov. The chaetal differences are as follows (see comparative Fig. 15): notochaetae in M. gloveri sp. nov. shaft is smooth, translucent while in M. linseae sp. nov. it is straw-coloured and distinctly horizontally striated (Fig. 15B and E). Further, notochaetae appear to be more numerous (~6), relatively slender and very long in M. gloveri sp. nov. (Fig. 15A), while in M. linseae sp. nov. these are stouter, short and fewer in numbers (usually only one or two observed) (Fig. 15D). Both species have two forms of neurochaete. The numerous, wide and flattened chaetae are very similar in both species. However, the additional few, slender neurochaetae appear to be different. In M. gloveri sp. nov. the serration is more dense, while in M. linseae sp. nov. the serration is more widely spaced (see Fig. 15C and F). As with notochaetae, neurochaetae are more numerous in M. gloveri sp. nov. Unfortunately, chaetae are susceptible to damage in both species and notochaetae in particular are often completely broken off, complicating the differentiation between these species. The differences observed are subtle and require careful observation but can be detected when specimens in good condition are available. It is possible that additional characters may be derived from elytra, which have unfortunately not been preserved in any of the specimens of M. linseae sp. nov. examined and only single observation of elytra was made for specimen of M. gloveri sp. nov. Molecular Information. COI and 16S were sequenced by Brasier et al. (2016), while 18S (1731 bp) was obtained in this study (Table 1). Based on COI, this species was closest to Macellicephala linseae sp. nov. with K2P distance 0.12 and uncorrected 'p' distance 0.11. Etymology. This species is named after Dr. Adrian Glover from the Natural History Museum, London who collected the polychaetes during the BIOPEARL II project and managed subsequent work on the polychaete material [see Neal et al. (2012); Neal et al. (2014); Brasier et al. (2016); Neal et al. (2017)]. Distribution.

The effects of drought on the water use, fruit development and oil yield from young olive trees
No full textIn Marlborough, New Zealand, olives are becoming an important crop alongside grapes. However, despite olives being drought resistant, they are generally planted on the poorer free-draining soils. Also, with the strong increase in cropping area, the demand for irrigation water has increased dramatically. In this research, we investigate the impact of short-term water stress on plant physiological processes, crop yield and oil quality in Marlborough, New Zealand. For that purpose, during the dry summer of 2000–2001, two trees were kept without irrigation for 64 days while two neighbouring trees were irrigated following standard practice. The treeswere measured for transpiration (E), leaf and stemwater potential (CL andCS), every other day, from dawn to dusk for three weeks from just before irrigation was started up again. All four trees were wired up for measuring stem sap flow (T) which was recorded hourly and a basic meteorological station provided weather data. Fruit and shoot development wasmeasured weekly. It was found that under the short period of dry conditions with soil moisture (() dropping to <5%, olive trees kept functioning at a very low level with CL and CS reduced from 1 to <4.0 MPa (T) reduced from 20 to 5 mm/h and (E) reduced from 1.5 to 1.0 mmol m2 s1. Within 10 days of restarting irrigation all these parameters were back to pre-drought levels. Both fruit and shoot growth came to a standstill within aweek after drought was induced. During the first few days after re-watering, a high variability in CL was found between leaves from the same trees. This variability disappeared after six days. Shoot growth did not recover after re-watering but fruit growth rate, became the same as for continuously irrigated trees within days, but fruit size did not manage to recover before harvest. Yield from the dry trees was low because berry and pit weight were reduced by almost 50% at harvest, had a lower oil and
percentage and were lower in phenolics. Stem sap flow was found to give a very good continuous measurement for the hydration status of the olive trees
Inflammatory components in human Alzheimer's disease and after active amyloid-β42 immunization
No full textInflammatory processes are important in the pathogenesis of Alzheimer's disease and in response to amyloid-β immunotherapy. We investigated the expression of multiple inflammatory markers in the brains of 28 non-immunized patients with Alzheimer's disease and 11 patients with Alzheimer's disease immunized against amyloid-β42 (AN1792): microglial ionized calcium-binding adaptor Iba-1, lysosome marker CD68, macrophage scavenger receptor A, Fcγ receptors I (CD64) and II (CD32); and also immunoglobulin IgG, complement C1q and the T lymphocyte marker CD3 using immunohistochemistry. The data were analysed with regard to amyloid-β and phospho-tau pathology, severity of cerebral amyloid angiopathy and cortical microhaemorrhages. In non-immunized Alzheimer's disease cases, amyloid-?42 correlated inversely with CD32 and Iba-1, whereas phospho-tau correlated directly with all microglial markers, IgG, C1q and the number of T cells. In immunized Alzheimer's disease cases, amyloid-β42 load correlated directly with macrophage scavenger receptor A-positive clusters and inversely with C1q. The severity of cerebral amyloid angiopathy and microhaemorrhages did not relate to any of the analysed markers. Overall, the levels of CD68, macrophage scavenger receptor A, CD64, CD32 and the number of macrophage scavenger receptor A-positive plaque-related clusters were significantly lower in immunized than non-immunized cases, although there was no significant difference in Iba-1 load, number of Iba-1-positive cells, IgG load, C1q load or number of T cells. Our findings indicate that different microglial populations co-exist in the Alzheimer's disease brain, and that the local inflammatory status within the grey matter is importantly linked with tau pathology. After amyloid-β immunization, the microglial functional state is altered in association with reduced amyloid-β and tau pathology. The results suggest that, in the long term, amyloid-β immunotherapy results in downregulation of microglial activation and potentially reduces the inflammation-mediated component of the neurodegeneration of Alzheimer's disease

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
