description: Here we report on several anomalies in quantum transport at the band center of a bipartite lattice with vacancies that are surely due to its chiral symmetry, namely: no weak localization effect shows up, and, when leads have a single channel the transmission is either one or zero. We propose that these are a consequence of both the chiral symmetry and the large number of states at the band center. The probability amplitude associated to the eigenstate that gives unit transmission ressembles a classical trajectory both with or without vacancies. The large number of states allows to build up trajectories that elude the blocking vacancies explaining the absence of weak localization.

description: Recent advances in machine learning have led to computer systems that are human-like in behaviour. Sentiment analysis, the automatic determination of emotions in text, is allowing us to capitalize on substantial previously unattainable opportunities in commerce, public health, government policy, social sciences, and art. Further, analysis of emotions in text, from news to social media posts, is improving our understanding of not just how people convey emotions through language but also how emotions shape our behaviour. This article presents a sweeping overview of sentiment analysis research that includes: the origins of the field, the rich landscape of tasks, challenges, a survey of the methods and resources used, and applications. We also discuss discuss how, without careful fore-thought, sentiment analysis has the potential for harmful outcomes. We outline the latest lines of research in pursuit of fairness in sentiment analysis.

Metallic iron for safe drinking water worldwide
Creators: name: Noubactep, C.
Publisher: name: FID GEO
Year: 2010

description: A new concept for household and large-scale safe drinking water production is presented. Raw water is successively filtered through a series of sand and iron filters. Sand filters mostly remove suspended particles (media filtration) and iron filters remove anions, cations, micro-pollutants, natural organic matter, and micro-organisms including pathogens (reactive filtration). Accordingly, treatment steps conventionally achieved with flocculation, sedimentation, rapid sand filtration, activated carbon filtration, and disinfection are achieved in the new concept in only two steps. To prevent bed clogging, Fe0 is mixed with inert materials, yielding Fe0/sand filters. Efficient water treatment in Fe0/sand filters has been extensively investigated during the past two decades. Two different contexts are particularly important in this regard: (i) underground permeable reactive barriers, and (ii) household water filters. In these studies, the process of aqueous iron corrosion in a packed bed was proven very efficient for unspecific aqueous contaminant removal. Been based on a chemical process (iron corrosion), efficient water treatment in Fe0 beds is necessarily coupled with a slow flow rate. Therefore, for large communities several filters should work in parallel to produce enough water for storage and distribution. It appears that water filtration through Fe0/sand filters is an efficient, affordable, an flexible technology for the whole world.

description: Tracking of breeding hoiho has resumed at Aramoana with deployments of GPS dive loggers on incubating birds in late October. Two penguins were fitted with AxyTrek devices on 16 and 24 October with devices recovered 8 and 6 days later, respectively. A third penguin was equipped with a new Ornitela GSM GPS dive transmitters which sends its data frequently via the mobile phone network. One AxyTrek and the Ornitela device both recorded GPS data showing that both penguins foraged within 20 km of Aramoana, reaching destinations some 15 km due east of Karitane. The second AxyTrek device failed to record GPS positions beyond the first hour of the first foraging trip undertaken; however, the bird followed a similar trajectory as the other two penguins and a full set of dive data was recorded. Tracking was paused during chick hatching. On 18 November 2019, a male hoiho guarding two healthy chicks was fitted with a camera logger and an AxyTrek. The camera was successfully recovered on 19 November 2019 containing 2.5 hours of footage recorded during the bird’s active foraging period (0920 - 11.55 hrs). Preliminary analysis suggest that the penguin caught principally opalfish over sandy bottom; during the 2.5 hours of camera footage the bird caught 20+ fish indicating excellent foraging success which aligns with healthy, well-nourished chicks in the bird’s nest. The GPS dive logger remained on the bird and is due for recovery on 22 November 2019.

description: Hoiho tracking is back in full swing. Deployments occurred over a broad range of site ranging from Bobby’s Head and Aramoana in North Otago to Long Point and Mahaka in the Catlins and the Bravo Islands in Paterson Inlet, Rakiura/Stewart Island. Mainland data have yet to be fully consolidated and will be summarized in the January 2020 report. In this report, we will focus primarily on data obtained from GPS and camera logger deployments on hoiho from the Bravo Group islands. Field work on the islands commenced on 30 November 2019. Initial nest searches found only 8 active nests (down from 15 nests in 2018), which were down to only six nests by the time the field team arrived. Of these nests, four were found to contain eggs, freshly hatched or chicks <1-week old so that device deployments on these nests were put off for another week. During this period a further three of the nests failed, all of which were nests that contained eggs or freshly hatched chicks in late November. Hence, only three nests remained for the tracking work. Between 30 November and 09 December 2019, all six remaining breeding birds were fitted with camera and GPS loggers. Two birds managed to pull off the cameras before the devices could be recovered; the remaining for cameras were recovered within 24 hours of deployment. GPS loggers remained on the birds for 4-7 days. Three of the six tracked birds foraged exclusively in Big Glory Bay. Two birds foraged further westwards into Paterson Inlet; one bird left the inlet and foraged closely along the coast to Wooding Bay (Maori Beach) before returning to the nest after a night at sea. Camera data is yet to be fully analysed but preliminary assessment indicates very diverse feeding strategies with one bird feeding exclusively on krill in Big Glory Bay, another bird going after whitebait, while the remaining two cameras suggest that birds target larger fish species, e.g. mullets. Overall, it appears that the penguins experienced excellent foraging conditions with most bird performing half-day trips. The low number of nests likely do not reflect the feeding situation but may be owing to a loss of breeding birds during last season’s mainland-wide starvation event as well as a very late start to the breeding season. High numbers of loafing adult on the island suggest that nest numbers could pick up again in the coming season. The study indicates that Rakiura/Stewart Island may represent a relative safe-haven for the hoiho mainland population and should receive increased monitoring attention in the future.

description: Drag reduction by polymers in turbulent flows raises an apparent contradiction: the stretching of the polymers must increase the viscosity, so why is the drag reduced? A recent theory proposed that drag reduction in agreement with experiments is consistent with the effective viscosity growing linearly with the distance from the wall. With this self consistent solution the reduction in the Reynolds stress overwhelms the increase in viscous drag. In this Letter we show, using Direct Numerical Simulations, that a linear viscosity profile indeed reduces the drag in agreement with the theory and in close correspondence with direct simulations of the FENE-P model at the same flow conditions.

description: Sustainability evaluation of crop and dairy production system was taken up in Tamil Nadu, India. Erode district was purposively selected for the present study. In the second stage, Erode, Modakkuruchi and Kodumudi blocks and four villages were selected purposively. From each production system, 40 farmers were selected at random and thus the total sample size was 160. Results indicated that both turmeric and sugarcane production systems were sustainable ecologically. Economically, turmeric cultivation was more sustainable by having higher stability and higher profitability. In social acceptability, turmeric was more sustainable in input self-sufficient index and while, sugarcane was more sustainable from equity criterion. Sustainable Rural Livelihood framework analyses revealed that foreign dairy production system was more sustainable. Livelihood security analyses showed that farmers of both the systems were sustainable. In integrated optimum plan, groundnut, tapioca, gingerly and green fodder was introduced as new enterprises and the gross cropped area was also increased. With respect to dairy enterprise, one foreign breed was introduced and at the same time, one local breed was reduced in the optimum plan. The policy advocacy suggested were credit policies, extension policies and future trading initiatives.

description: In this paper, we investigate the possibility that the Universe is driven by a single dark fluid described by a Lambert $W$ equation of state parameter, $w_{eff}$, which is essentially dependent on two parameters $\vartheta_{1}$ and $\vartheta_{2}$ which need to be fixed from observations. We obtain the constraints on these parameters using the latest 51 data points of $H(z)$ measurements, spanning the redshift range $0.07\leq z \leq 2.36$. The present study shows that the Universe is indeed undergoing an accelerated expansion phase following the decelerated one at the transition redshift, $z_{t}=0.77\pm0.03$ ($1σ$) and is well consistent with the recent observations. We also find that at low redshifts, $w_{eff}$ evolves only in the quintessence regime ($-1

description: The impact of wood combustion on ambient aerosols was investigated in Augsburg, Germany during a winter measurement campaign of a six-week period. Special attention was paid to the high time resolution observations of wood combustion with different mass spectrometric methods. Here we present and compare the results from an Aerodyne aerosol mass spectrometer (AMS) and gas chromatographic – mass spectrometric (GC-MS) analysed PM1 filters on an hourly basis. This includes source apportionment of the AMS derived organic matter (OM) using positive matrix factorisation (PMF) and analysis of levoglucosan as wood combustion marker, respectively. During the measurement period nitrate and OM mass are the main contributors to the defined submicron particle mass of AMS and Aethalometer with 28% and 35 %, respectively. Wood combustion organic aerosol (WCOA) contributes to OM with 23% on average and 27% in the evening and night time. Conclusively, wood combustion has a strong influence on the organic matter and overall aerosol composition. Levoglucosan accounts for 14% of WCOA mass with a higher percentage in comparison to other studies. The ratio between the mass of levoglucosan and organic carbon amounts to 0.06. This study is unique in that it provides a one-hour time resolution comparison between the wood combustion results of the AMS and the GC-MS analysed filter method at a PM1 particle size range. The comparison of the concentration variation with time of the PMF WCOA factor, levoglucosan estimated by the AMS data and the levoglucosan measured by GC-MS is highly correlated (R2 = 0.84), and a detailed discussion on the contributors to the wood combustion marker ion at mass-to-charge ratio 60 is given. At the end, both estimations, the WCOA factor and the levoglucosan concentration estimated by AMS data, allow to observe the variation with time of wood combustion emissions (gradient correlation with GC-MS levoglucosan of R2 = 0.84). In the case of WCOA, it provides the estimated magnitude of wood combustion emission. Quantitative estimation of the

description: Bacterial wilt (BW} is due to Pseudomonas solanacearum (Smith) Smith, a soilborne and a xylem-invading bacteria. These properties and high variation in strains, aggressiveness, depending on environmental factors, make it difficult to bring this tropical world-wide disease under control. Fren research projects including co-workers from different institutes (CIRAD, INRA, ORSTOH) based in metropolitan France and in overseas departments are briefly reported. Recent results obtained by INRA-CRAAG's phytobacteriological laboratory include: The behavior of P. solanacearum in receptive and suppressive soils; Characteristics of local strains, especially host range and aggressiveness; The existence of healthy carriers among tomato plants, i.e., plants bearing latent infections in vascular tissues, Programs are being developed according to two complementary control strategies interdependent from results obtained by molecular biologists and breeders. They are: Biological control of BW using genetically constructed avirulent mutants; and BW resistance mechanisms, with particular attention to bacterial colonization (density, localization) and to incidence of environmental factors on resistance of cultivars.

description: Assuming that axial-vector and scalar diquarks exist in the Quark-Gluon Plasma near the critical temporature $T_c$, baryons can be produced from quark-diquark interactions. In RHIC conditions ($\sqrt{s_{NN}} = 130GeV$ and $200GeV$), the ratio $\barΩ^+/Ω^-$ may be larger than 1, based on the concept that QGP with diquarks would exist. This unusual result might be a helpful evidence for QGP existing in RHIC.

description: A field experiment was establi3hed on Corozal clay (Aquic Tropudults) to evaluate the effect of periodic applications of chicken manure on plantain (cv. Haricongo) performance and yield. Plantain plants receiving periodic applications of manure, up to 7.26 kg/plant/crop, showed similar growth and yield to the check plants fertilized with the fertilizer formula 10-5-15 + sulpomag. Plantain bunch weight of the manure treated plots ranged from 13.44 to 18.91 kg and the number of fruits ranged from 41.7 to 49.4 fruits/bunch. Average bunch weight and average number of fruits of the check treatment was 13.04 kg and 41.7 fruits/bunch, respectively. Among leaf samples collected at four and nine months after planting, very little variation in nutrient concentration and content was observed among treatments.
Protocol enhancement and network formation techniques in IEEE 802.15.3 WPANs
Creators: name: Yin, Zhanping
Publisher: name: University of British Columbia
Year: 2011

description: Designed for high rate wireless personal area networks (WPANs), the IEEE 802.15.3 protocol enables peer-to-peer communications between devices (DEVs) with quality of service (QoS) support. This thesis presents several performance enhancement methods and scatternet formation techniques for 802.15.3 networks. Considering piconet coverage and multi-rate carriers, we first propose a Third-Party Handshake Protocol (3PHP) for fast peer discovery and connection reestablishment. With the active involvement of the piconet coordinator (PNC), 3PHP guarantees full piconet connectivity, and achieves faster peer discovery by removing the peer discovery overhead and eliminating costly upper layer routing between directly unreachable DEVs by a more reliable and efficient MAC layer forwarding. Second, we develop intra-piconet route optimization algorithms in the PNC with application awareness through self-learning the achievable data rates between DEVs, which significantly increase the system performance in terms of reducing transmission time and increasing effective data rate, and thus reduce power consumption and increase piconet capacity. Furthermore, we propose a frame aggregation strategy for efficient frame transmissions in 802.15.3 Contention Period (CPs), and model the CP in each superframe as a contention resolution problem. We further propose a novel Adaptive CP Suspend (ACS) scheme that significantly shortens the effective region in a CP, thus greatly reducing the system energy cost by allowing DEVs to sleep during the suspended parts of the CPs. ACS adapts to varying channel traffic and collision situations by employing a CP counter at the PNC. Finally, we investigate the 802.15.3 scatternet formation problem. Configuration of scatternets needs to consider the piconet size and channel reuse, given the number of logical channels available. We first evaluate the effect of piconet size on the expected scatternet connection rate, and show that a medium sized piconet radius yields the best scatternet connection data rate taking into account of channel reuse. Moreover, we propose a stochastic scattenet formation algorithm to avoid neighbor information gathering in 802.15.3 networks. With only 20% more piconets than the ideal but impracticable greedy algorithm, the stochastic method scales well with network size, achieves better connectivity, requires less maintenance and is robust and stable with respect to changes in the WPAN.

description: Terra Seismic can predict most major earthquakes (M6.2 or greater) at least 2 - 5 months before they will strike. Global earthquake prediction is based on determinations of the stressed areas that will start to behave abnormally before major earthquakes. The size of the observed stressed areas roughly corresponds to estimates calculated from Dobrovolskys formula. To identify abnormalities and make predictions, Terra Seismic applies various methodologies, including satellite remote sensing methods and data from ground-based instruments. We currently process terabytes of information daily, and use more than 80 different multiparameter prediction systems. Alerts are issued if the abnormalities are confirmed by at least five different systems. We observed that geophysical patterns of earthquake development and stress accumulation are generally the same for all key seismic regions. Thus, the same earthquake prediction methodologies and systems can be applied successfully worldwide. Our technology has been used to retrospectively test data gathered since 1970 and it successfully detected about 90 percent of all significant quakes over the last 50 years.
title: A study of specific learning difficulties in tertiary education
Creators: name: Gauntlett, David Allan
Publisher: name: The Open University
Year: 1988

description: This study is unique in investigating instances of Specific Learning Difficulties (Dyslexia) among mature students in British institutes of tertiary education. Despite growing awareness of this condition, it is only during the last thirty years that cases of dyslexia among adults have been distinguished from aphasia. Assessments were conducted using a structured questionnaire, psychometric tests, measures of attainment, vocational interest and personality. Test results provided support for the view that dyslexia is characterised by a discrepancy between language skills and intellectual ability accompanied by measurable cognitive differences. Significant differences were found on tests of short term memory, while spelling difficulties were the most enduring form of written language difficulty. Differences found on measures of personality, are thought to reflect an interaction between personality and coping strategies. Most subjects had felt constrained to take Jobs with a low interest level, ie. they had compromised their vocational interests and subsequently achieved lower socio-economic status than their fathers. The investigation into the provision made by British universities revealed that very few have any formal policy for dealing with dyslexic students. Most were unable to state what course support or examination concessions were available. In a study of factors related to modality, dyslexic students took longer to read material and remembered less than other groups. When using multi-modal material dyslexic subjects remembered more but must reconcile improving their recall ability with the expense of spending more time. In a second study of factors thought to influence the marking of scripts It was found that higher marks were not awarded to typewritten scripts free from spelling errors. Changes in format only influenced the focus of the tutors' comments. The conclusions are that dyslexia does not improve spontaneously, the dyslexic child is likely to become a dyslexic adult who will continue to experience difficulties with language skills, especially spelling, while the individuals educational, social and occupational ambitions are likely to be compromised because of their specific learning difficulties.

description: The two-photon-exchange (TPE) effect plays a key role to extract the form factors (FFs) of the proton. In this work, we present some exact properties on the TPE effect in the elastic $ep$ scattering based on four types of typical and general interactions. The possible kinematical singularities, the asymptotic behaviors and the branch cuts of the TPE amplitudes are analyzed. The analytic expressions clearly indicate some exact relations between the dispersion relation (DR) method and the hadronic model (HM) method. It suggests that the two methods should be modified to general forms, respectively. After the modifications the new forms give the same results. Furthermore, they automatically and correctly include the contributions due to the seagull interaction, the meson-exchange effect, the contact interactions and the off-shell effect. To analyze the elastic $e^{\pm}p$ scattering data sets, the new forms should be used.

description: The effect of the absorbing sites with an absorbing rate $β_{0}$, in both one absorbing site (one way out) and two absorbing sites (two ways out) in a road, on the traffic flow phase transition is investigated using numerical simulations in the one-dimensional cellular automaton traffic flow model with open boundaries using parallel dynamics.In the case of one way out, there exist a critical position of the way out $ i_{c1}$ below which the current is constant for $β_{0}$$$$β_{0c2}$. When the way out is located at a position greater than $ i_{c2}$, the current increases with $β_{0}$ for $β_{0}$$$$β_{0c2}$. In the later case the density undergoes two successive first order transitions; from high density to maximal current phase at $β_{0}$$=$$β_{0c1}$ and from intermediate density to the low one at $β_{0}$$=$$β_{0c2}$. In the case of two ways out located respectively at the positions $ i_{1}$ and $ i_{2}$, the two successive transitions occur only when the distance $i_{2}$-$i_{1}$ separating the two ways is smaller than a critical distance $d_{c}$. Phase diagrams in the ($α,β_{0}$), ($β,β_{0}$) and ($i_{1},β_{0}$) planes are established. It is found that the transitions between Free traffic, Congested traffic and maximal current phase are first order.

description: Several fruitless attempts to recover a satellite tag from a male hoiho fitted with the device in Penguin Bay in late July have been made. The satellite tags stopped transmitting on 18 September which may be indicative of the bird being stationary in a location where transmission is blocked (i.e. nest site under dense vegetation). The last known fix is from Jacks Bay which probably explains why searches for the bird at Penguin Bay were without result. Otherwise field work has been suspended due to the penguins now intensive preparations for the upcoming breeding season. Pairs have been found to spend the days together at potential nest sites. Unfortunately, from the numbers of birds observed at our current study site in Penguin Bay, we may have to expect another drop of nest numbers this year. The field work downtime provided the time to perform the dive analysis of the satellite tagged bird recovered in late August.

description: The premise of this research note is that current research on metallic iron (Fe0) for environmental remediation and water treatment has started on a biased basis. Before expecting experienced researchers to correct flawed approaches compromising the future of the technology, the attention of new researchers should be drawn on the prevailing flawed conceptual models. There are guides on how to select good research topics, to perform good literature review, to select good mentors, and to write good scientific papers. But critically reviewing the published material is part of the competence of any new researcher in a given field of research. This research note summarizes the most critical issues of research on Fe0 for water treatment as asks some key questions which would help research beginners to find their way.

description: Histological observations of the ovaries of the abscised reproductive structures (at anthesis) in the dwarf pigeonpea cultivars (UWlO, UW17 and UW26) showed a high incidence of unfertilized ovules (76-90 per cent. In the ovaries of the excised immature pods (post-anthesis) of the above cultivars, a comparatively low proportion of unfertilized ovules (14-17 per cent) was observed. A slightly higher proportion of unfertilized ovules (26-33 per cent) was observed in mature pods of the three cultivars, Statistical analyses revealed no significant differences in the number of unfertilized ovules among the cultivars studied in the abscised, excised, and mature reproductive structures of pigeonpea. These results suggest that, in pigeonpea, there is no critical number of ovules which need to be fertilized in order for successful pod-set to occur.
Neutrino Mixing by modifying the Yukawa coupling structure of constrained sequential dominance

description: In the constrained sequential dominance (CSD), tri-bimaximal mixing (TBM) pattern in the neutrino sector has been explained, by proposing a certain Yukawa coupling structure for the right-handed neutrinos of the model. However, from the current experimental data it is known that the values of neutrino mixing angles are deviated from the TBM values. In order to explain this neutrino mixing, we first propose a phenomenological model where we consider Yukawa couplings which are modified from that of CSD. Essentially, we add small complex parameters to the Yukawa couplings of CSD. Using these modified Yukawa couplings, we demonstrate that neutrino mixing angles can deviate from their TBM values. We also construct a model, based on a flavor symmetry, in order to justify the modified form of Yukawa couplings of our work.

Das Wildmoos am Geißbühel (1250 m NN) ist ein häufig beweidetes und daher weitgehend offenes Moor, das durch Zuflüsse aus den lockeren Schuttmassen eines alten Bergsturzes gespeist wird. Die Torfe sind bis zu gut 1,5 m mächtig. Das 14C-Alter eines Fichtenstubbens aus 1,6 m Tiefe beläuft sich auf 4135 ± 70 BP (konv.), so dass der „Geißbühel-Bergsturz“ um 3000 v. Chr. niedergegangen sein muss. Die Torfbildungsrate lag bei 0,3 bis 0,4 mm/Jahr. Die Makrofossilbefunde beginnen basal mit floristischen Hinweisen auf zeitweilig nicht sehr nasse Be- dingungen. In den hangenden Torfen folgt ein beständig artenreicher werdendes Spektrum von Moor- pflanzen ausschließlich sehr saurer und nährstoffarmer Standorte. Mindestens während dreier Jahrtau- sende hat das Moor in seinen nassen Bereichen diese sehr einheitliche Pflanzendecke getragen. In den jüngsten Ablagerungen deuten Wandlungen im Pollenbild auf die Zuwanderung der Walser gegen 1300 n. Chr. und ihre Viehwirtschaft hin. Das Windecksattel-Moor (1750 m NN) ist ein Sattelmoor und teilweise von dichten Latschenkieferge- büschen bedeckt. Von Süden kommende Zuflüsse werden durch die oberflächennah anstehenden Drus- bergschichten gestaut und haben zu einer bis zu 1,8 m mächtigen Moorbildung geführt. Die 14C-Datie- rung eines Kiefernstubbens aus einer Tiefe von 1,55 m ergab ein Alter von 2175 ± 45 BP (konv.). In den Torfen haben sich keine nennenswerten Wandlungen vollzogen. Unter den Resten der Höheren Pflanzen ließen sich bis zur Basis der Torfe praktisch keine „Kalkpflanzen“ finden, und auch „Kalk- moose“ traten nur selten auf. Verbreitet waren Arten sehr saurer und nährstoffarmer Standorte.

description: The traditional roles of genebanks and breeders in crop improvement programs have been strongly breeder-oriented in commodity collections curated by breeders. Genebanks housing a diversity of crop species have generally been curatorially oriented with little support or effort in plant development programs. With the recognition of the importance of genebanks in conserving valuable genetic resources, the demand for more than just curation of the materials has increased to include the assessment of the material for the user community. Relocation of the National Small Grains Collection from Beltsville to Aberdeen, Idaho, has placed the collection with scientists taking selected material from raw germplasm to enhanced germplasm which can be used by breeders nationwide. This is a new model for the potential of genebanks where extensive evaluation and enhancement activities are taking place and the germplasm released to public and private breeders. Where a weakness in the total public breeding program effort has reduced the number of scientists transferring genes from wild and weedy relatives into usable genetic material, this may offer an opportunity to renew this aspect of the breeding continuum. As molecular technologies enable scientists to have a clearer understanding of the diversity pools from which the raw germplasm has been derived, there is opportunity to build genepools for heterotic diversity to be instrumental in increasing crop productivity. Much of this work could be incorporated into the evaluation and enhancement programs located at the genebanks of the National Plant Germplasm System.

description: For thousands of years conventional breeding techniques have been used to improve crop plants. Emerging biotechnologies enable us to work at the whole plant as well as the organ, tissue, cell, protoplast, chromosome and gene levels in our efforts to modify plants. Biotechnology has loosely been defined to include a collection of techniques including gene mapping, recombinant DNA, Aqrobacteriummediated gene transfer of recombinant DNA, DNA and chromosome microinjection, microprojectile bombardment, protoplast fusion, selection for somaclonal variation, embryo rescue, anther culture and micropropagation. Plants with disease resistance, pest resistance, herbicide tolerance, drought tolerance and increased yield have been produced using one or a combination of these techniques. The application of several of these techniques to the improvement of peach will be discussed. Plant breeding in combination with biotechnology provide a bright future for the improvement of crop plants.

description: Crop improvements have been one of the most important human endeavors in history, for a very good reason - survival. Initially such improvements were achieved by repeated selections for quantity and quality of food as guided by experience only. Further advancement was made by our forefathers who recognized that both animals and plants could be selected and crossed to reproduce and upgrade species. The knowledge of genetics guided the development of the breeding program from its infancy to maturity, eventually leading it into the era of the green revolution and gene revolution. The inital breeding program was based on the principles of genetics. By classical manipulation of chromosomes, many new varieties or species of important crops were created through hybridization, pure line selections and mutations. The contribution of the breeding techniques reached their peak in improving crop productivity in the 1960's. The achievements were so dramatic, it is referred to as the green revolution. These operations have limitations such as sexual incompatibility. To overcome these limitations the tissue culture techniques were developed in the 1950's. This led to the development of protoplast fusion in the 1970's. The contributions made by these new technologies have been enormous and more importantly they paved the way for the current advancement of biotechnology. The application of biotechnology to crop improvement ushers us into a new era of the gene revolution.

description: Cardiac muscle cells can exhibit complex patterns including irregular behaviour such as chaos or (chaotic) early afterdepolarisations (EADs), which can lead to sudden cardiac death. Suitable mathematical models and their analysis help to predict the occurrence of such phenomena and to decode their mechanisms. The focus of this paper is the investigation of dynamics of cardiac muscle cells described by systems of ordinary differential equations. This is generically performed by studying a Purkinje cell model and a modified ventricular cell model. We find chaotic dynamics with respect to the leak current in the Purkinje cell model, and EADs and chaos with respect to a reduced fast potassium current and an enhanced calcium current in the ventricular cell model -- features that have been experimentally observed and are known to exist in some models, but are new to the models under present consideration. We also investigate the related monodomain models of both systems to study synchronisation and the behaviour of the cells on macro-scale in connection with the discovered features. The models show qualitatively the same behaviour to what has been experimentally observed. However, for certain parameter settings the dynamics occur within a non-physiological range.

description: This research explores the lived experiences of junior and senior undergraduate student subjects from the FGLID (First-Generation, Low-Income, and/or Disabled) community facing significant barriers in the realm of higher education. The challenges contribute to the broadening of the educational gap, observable in lower graduation and persistence rates compared to non-FGLID peers (Jeong et al., 2023; Longwell-Grice et al., 2016; Mikell & Davis, 2022). The study follows a descriptive qualitative research design and provides insights into the lived experience of FGLID participants through a semi-structured interview process. This study employed a strength-based approach (Weick et al., 1989) and was guided by Chickering and Reisser's (1993) theory of student development which focuses on the seven vectors of identity development as well as the impact of environmental influences. Results generated 26 codes, with the top nine most prominent emerging as significant in theme generation. Participants' contributions revealed three central themes in understanding the lived experience of FGLID students and factors contributing to their ability to persist: (1) the state of social capital, (2) the existence of a resource framework, and (3) the process of identity formulation. These themes, while affirming aspects of Chickering and Reisser's (1993) framework, also highlighted areas where further exploration is needed such as deeper exploration into the sub-demographics of the FGLID population, exploring the impact of the physical environment, and seeking to understand the correlation of the grief processes in the development of identity and one's ability to navigate challenges.

title: Medical Developments and Religious Belief with Special Reference to Europe in the 18th and 19th Centuries
Creators: name: Farr, Alfred Derek

description: It has frequently been suggested that, historically, science and religion react together in a state of conflict. Three areas of medical development have been studied to determine the nature of such conflict in this field where, in particular, its existence has been alleged. The introduction into Europe of inoculation for smallpox, about 1720, seems to have been met by religious objections from some hyper-Calvinist sources - particularly in Scotland - but this opposition had almost disappeared by the 19th century, and it did not recur on the introduction of cowpox vaccination by Jenner in 1798. Obstetric anaesthesia is commonly said to have stimulated massive religious opposition when it was introduced in 1847. Evidence of such opposition in contemporary sources has proved to be virtually non-existent, however, and it appears that this 'conflict' is a myth, based upon a defence prepared by James Young Simpson of Edinburgh against an attack which never materialized. The value given to the life of unborn children was a source of genuine conflict between the medical profession - which regarded the fetus as disposable - and the Roman Catholic church - which regarded all life as valuable, even that of the unborn. Debates occurred over induced abortion, embryotomy, and the caesarian operation -a means of saving the child which the catholic church supported, but surgeons regarded as unacceptably dangerous for the mother. These differences continued until-well into the present century. It is concluded that, while occasional specific disputes have occurred, there is no evidence of any general 'warfare' between medicine and religion, and that such a conflict is merely an historiographical artifact based upon past failures to study the historical evidence sufficiently closely.
