description: We test the reliability of infrared (IR) emission to trace star formation in individual star-forming sites of M33, and outline a new method for testing the distribution function of massive stars in newly formed clusters. We select IR sources from the Spitzer survey of M33 and show that the IR and Halpha luminosities are not correlated. Complementing the infrared photometry with GALEX-UV data, we estimate the source bolometric luminosities. For a given stellar IMF we simulate a theoretical curve for the expected bolometric-to-Halpha luminosity ratio, along which stellar clusters are born. We call this the cluster birthline in the Lbol--Lbol/LHal plane. The birthline is flat for Lbol>3x10^{39}erg/s because all clusters fully sample the IMF and it increases toward lower luminosities as the upper end of the IMF becomes incompletely sampled. The observations of M33 show that young isolated clusters lie close to the theoretical birthline for a wide range of Lbol. The luminosity is not proportional to Halpha emission for low mass clusters and aging moves clusters above the birthline. The best fit to the birthline is for a randomly sampled IMF, in which the mass of most massive star in a cluster is not strictly limited by the cluster's mass. We also find that the IR luminosity of young stellar clusters in M33 is not proportional to their bolometric luminosity. This irregularity could be the result of low and patchy dust abundance in M33.

description: We present the discovery of four remote star clusters in M33, one of which is of an extended nature. Three of the clusters were discovered using survey data from the Isaac Newton Telescope Wide-Field Camera while one was discovered serendipitously in a deep image taken with the Hubble Space Telescope's Advanced Camera for Surveys. With projected radii of 38-113 arcmin (9.6-28.5 kpc for an assumed M33 distance of 870 kpc), these clusters lie significantly beyond all but one of the currently-confirmed clusters in M33. The clusters have magnitudes and colors consistent with their being old to intermediate-age globular clusters. Indeed, they bear a strong resemblance to the outer halo GC population of the Milky Way and M31 in terms (V-I)o colors. The three outermost clusters are projected on the far side of M33 with respect to M31, an asymmetry that could suggest tidal interactions have affected M33's globular cluster distribution at large radii.

description: We present the results of a mixed action approach, employing dynamical twisted mass fermions in the sea sector and overlap valence fermions, with the aim of testing the continuum limit scaling behaviour of physical quantities, taking the pion decay constant as an example. To render the computations practical, we impose for this purpose a fixed finite volume with lattice size $L\approx1.3$ fm. We also briefly review the techniques we have used to deal with overlap fermions.

description: Exciton spin dynamics in quasi-spherical CdS quantum dots is studied in detail experimentally and theoretically. Exciton states are calculated using the 6-band k.p Hamiltonian. It is shown that for various sets of Luttinger parameters, when the wurtzite lattice crystal field splitting and Coulomb interaction between the electron-hole pair are taken into account exactly, both the electron and hole wavefunction in the lowest exciton state are of S-type. This rules out the spatial-symmetry-induced origin of the dark exciton in CdS quantum dots. The exciton bleaching dynamics is studied using time- and polarization-resolved transient absorption technique of ultrafast laser spectroscopy. Several samples with a different mean size of CdS quantum dots in different glass matrices were investigated. This enabled the separation of effects that are typical for one particular sample from those that are general for this type of material. The experimentally determined dependence of the electron spin relaxation rate on the radius of quantum dots agrees well with that computed theoretically.

description: A search for high-mass resonances in the $e^+e^-$ final state is presented based on 2.5 fb$^{-1}$ of $\sqrt{s}=$1.96 TeV $p\bar{p}$ collision data from the CDF II detector at the Fermilab Tevatron. The largest excess over the standard model prediction is at an $e^+e^-$ invariant mass of 240 GeV/$c^2$. The probability of observing such an excess arising from fluctuations in the standard model anywhere in the mass range of 150--1,000 GeV/$c^2$ is 0.6% (equivalent to 2.5 $σ$). We exclude the standard model coupling $Z'$ and the Randall-Sundrum graviton for $k/\overline{M}_{Pl}=0.1$ with masses below 963 and 848 GeV/$c^2$ at the 95% credibility level, respectively.
Transforming African Cities: United Nations Technical Assistance, Urban Development, and Modernization in a Decade of Decolonization, c. 1955–1965

description: United Nations experts played an important role in formulating policies of urban development in Sub-Saharan Africa during the late 1950s and early 1960s. Even though the process of rapid urbanization in the region had begun in the 1920s, colonial regimes had been slow to react to this challenge. Thus, governments of the newly independent countries were confronted with a number of structural problems, among them the lack of an efficient building materials industry and qualified personnel or the virtual non-existence of data and statistics. In this context, a discourse on strategies to cope with the challenge developed that went far beyond pragmatic approaches and involved more general questions about the interrelationship of urbanization, modernization and development in Sub-Saharan Africa.

Breeding biology of the American Robin (Turdus migratorius)
Creators: name: Kemper, Dorothy Lynne
Publisher: name: University of British Columbia
Year: 2011

description: The American Robin (Turdus migratorius) in southwestern British Columbia was studied in regard to timing of reproduction, breeding biology, gonadal changes with time, and the relationship between photoperiod and gonadal condition. The basic breeding biology is similar to that found for other robins in the eastern and midwestern United States. The only marked difference is the very high nesting success rate of the robins which I studied. The overall success rate was 86.6 percent with 87.8 percent of all eggs laid hatching and 98.6 percent of these fledging. The onset of the breeding season was marked by the increase in territorial aggressive behaviour of male robins. This increase is a gradual process taking place over a two month period from early February until late March. The histological pattern of testes development and regression in the robin is the same as that for other temperate zone passerines. The length of the daily photoperiod has a definate effect on the timing of testicular recrudescence. The average testes weights of robins kept on eight, 12, and 16 hour photoperiods for the period of the annual cycle when testicular development occurs in the wild were 9.4 mg., 14.6 mg., and 200.5 mg. respectively. As well as stimulating gonadal development increasing photoperiod, as opposed to short day lengths, affects migratory behaviour as evidenced by Zugunruhe or night restlessness.

description: We show that room temperature resistivity of Ba0.5Sr1.5Zn2Fe12O22 single crystals increases by more than three orders of magnitude upon being subjected to optimized heat treatments. The increase in the resistivity allows the determination of magnetic field (H)-induced ferroelectric phase boundaries up to 310 K through the measurements of dielectric constant at a frequency of 10 MHz. Between 280 and 310 K, the dielectric constant curve shows a peak centered at zero magnetic field and thereafter decreases monotonically up to 0.1 T, exhibiting a magnetodielectric effect of 1.1%. This effect is ascribed to the realization of magnetic field-induced ferroelectricity at an H value of less than 0.1 T near room temperature. Comparison between electric and magnetic phase diagrams in wide temperature- and field-windows suggests that the magnetic field for inducing ferroelectricity has decreased near its helical spin ordering temperature around 315 K due to the reduction of spin anisotropy in Ba0.5Sr1.5Zn2Fe12O22.

description: Tetranectin–plasminogen interaction plays a defining role in extracellular matrix degradation, enabling tumor cell invasion and metastasis. This interaction occurs via the carbohydrate recognition domain (CRD) and Kringle 4 domain of tetranectin and plasminogen, respectively, leading to activation of the plasminogen-cascade that triggers the proteolytic processes. Thus targeting this interaction represents an important strategy to suppress tumor cell migration and invasion. In this direction, we attempted to target the CRD of tetranectin to inhibit its interaction with the Kringle-4 domain of plasminogen using natural bioactive compounds. A cheminformatics pipeline for drug designing and screening was utilized to obtain lead compound(s) that exhibit conformationally and energetically viable CRD binding. Out of 206 compounds screened, diosgenin and scytonemin displayed the most favorable interactions with CRD. Short-term molecular dynamics simulations of 20 ns were employed to further study the conformational stability of both compounds with tetranectin CRD which reflected at the increased stability of diosgenin in the CRD binding pocket compared to scytonemin. Finally, an extended molecular dynamic simulation of 100 ns affirmed the robust and stable interaction of diosgenin with CRD. Furthermore, diosgenin was observed to exert a pronounced anti-proliferative effect on high tetranectin-expressing MDA-MB-231 breast cancer cells. The inhibitory effect of diosgenin on the tetranectin–plasminogen interaction was corroborated by the reduced migration and invasiveness of MDA-MB-231 cells under diosgenin treatment. Overall the study presents an alternate and safer approach to impede breast cancer metastasis and delineates the novel anti-metastatic activity of diosgenin. Communicated by Ramaswamy H. Sarma

description: Аннотация. В статье тыл рассматривается с точки зрения хозяйственно-экономического устройства всей системы обороны СССР, как совокупность военных и гражданских сил, которые задействованы в обеспечении необходимыми ресурсами военных подразделений и гражданского населения. Сделан вывод, что колоссальные усилия и жертвы работников тыла стали весомым вкладом в Победу. Без трудового подвига советского народа одолеть врага было бы невозможно так же, как и без побед на фронте. Страна не забыла своих героев. По окончании войны десятки тысяч тружеников тыла удостоились высоких правительственных наград. И в наши дни их подвиг не забыт: в знак этого в Российской Федерации 70 городов носят почетное звание «Город Трудовой Доблести». 

Abstract. The article examines the rear from the point of view of the economic structure of the entire defense system of the USSR, as a combination of military and civilian forces involved in providing military units and the civilian population with the necessary resources. It is concluded that the colossal efforts and sacrifices of rear workers became a significant contribution to the Victory. Without the labor feat of the Soviet people, it would have been impossible to defeat the enemy, just as it was impossible without victories at the front. The country has not forgotten its heroes. At the end of the war, tens of thousands of rear workers were awarded high government awards. And their feat has not been forgotten today: as a sign of this, 70 cities in the Russian Federation bear the honorary title of "City of Labor Valor".

description: A series of halogenated chalcone derivatives were designed and developed for anti-tubercular activity. Novel molecules were designed and in-silico screening were performed using admetSAR, SwissADME, and Osiris Property Explorer. From the initial filter the top 10 compounds were docked using the Autodock tool 1.5.6. and the binding energies of the docked compounds were higher than the standard drugs Isoniazid.and Ethionamide. Based on the in-silico and docking results, the top halogenated chalcones were synthesized and characterized using FT-IR, mass spectrometry, 1H, and 13C NMR spectroscopy. The chalcones were further evaluated for anti-tubercular activity using MABA against the H37Rv strain. Among the series of compounds, DK12 and DK14 showed potent in-vitro activity, with MICs of 0.8 µg/ml, in comparison with 1.6 µg/ml of the first-line drug Isoniazid. Further molecular dynamics simulations studies for 100 ns revealed that the key interaction with TYR 158 were observed in both DK12 and DK14 in the InhA active site. The compound DK12 further showed significant interactions with PHE 149 and ARG 153 residues and is a hit molecule among the series. Further DK12 and DK14 does not show any significance toxicity. The compounds DK12 needs to be optimized and further investigation to be carried out against InhA. Communicated by Ramaswamy H. Sarma

description: This thesis is comprised of four chapters, including a systematic literature review, an empirical research paper, a critical appraisal, and the ethics application section. The systematic literature review offers a meta-synthesis of the published literature exploring the experiences of men who self-harm in forensic secure hospitals and prisons. Five papers were included in the review, four were conducted in prisons and one in a forensic secure hospital. The results were synthesised using a meta-ethnographic approach. The empirical paper is a qualitative investigation that explores the experiences of young men who self-harm, attending to the relational and communicative aspects of these behaviours. This study utilised semistructured interviews to gather the perspectives of five young men who self-harm and the data was analysed using Interpretative Phenomenological Analysis. The critical appraisal offers an overview of both papers, highlighting the main findings, as well as difficulties that arose during the research process, and the key clinical and research implications of the whole thesis. Personal reflections are also offered. The last section includes the ethics application process of the empirical paper and the supporting documents utilised in the process.
Growth of the southern elephant seal Mirounga leonina (Linnaeus 1758) at Macquarie Island
Creators: name: Bell, CM
Publisher: name: University Of Tasmania
Year: 2023

description: Body growth was an essential component of early biological research undertaken to develop sustainable harvesting methods of the southern elephant seal (Mirounga leonina Linnaeus 1758). Since slaughter ceased in most areas earlier this century, a substantial decline in numbers of elephant seals has been recognised at several of the main breeding sites, stimulating interest in life-history attributes which may help provide an explanation for these declines. Growth of elephant seals from the Macquarie Island population was investigated to quantify the current growth pattern and to compare with the stable population at South Georgia, where elephant seals were known to be larger, grow faster, and breed earlier. A method was developed to indirectly measure body mass using photogrammetry. Predictive models were developed using photographic images alone, but when compared with models based on measured morphological characteristics, the best predictor of body mass was a combination of body length and girth squared. Growth during the first foraging trip was described and found to reflect the hindrances of early life at sea. Growth was hypothesised to comprise primarily of adjustment to body composition, rather than increase in net body size. Both sexes may exploit similar marine resources during the first foraging trip, as no significant difference in body growth was found. Interspecific comparison suggested that southern elephant seals grow considerably more than northern elephant seals (Mangustirostris) during this period, and that this may be related to prey abundance and distribution. A cross-sectional growth study was undertaken for females up to 15 years of age. Dental cementum layers were counted to estimate the age of some animals, which proved to be a relatively accurate and useful technique. The snout-tail length of adult Macquarie Island cows has increased significantly since the 1950s and 1960s, and is now similar to that of the current South Georgia population. The temporal changes at in snout-tail length at Macquarie Island are consistent with either a population equilibration process or long-term environmental change reducing population density. These findings provide little supporting evidence for a particular cause of the Macquarie Island population decline, but the most likely scenario is that several factors are implicated, these having resulted in changes in marine resource availability. Body growth of southern elephant seals is determined by many factors, but prey abundance and distribution are fundamental influences on all growth stages. Other factors which may play a role include harem disturbances, behaviour of weaners, disease, juvenile body size and stored energy reserves.

description: RNA-dependent RNA polymerase, also known as RdRp, is a possible therapeutic target that could be used to suppress the proliferation of RNA viruses such as SARS-CoV-2. This protein has two major functional sites (a) catalytic and (b) substrate entry, which regulate the natural substrate entry and its corresponding interaction with the protein. In this study, a computational drug design pipeline was applied to investigate potential inhibitors against SARS-CoV-2 RdRp from Lauraceae plants, and five top hits were selected based on the docked score (< −7 kcal/mol). The docking study suggested that the Glochidioboside had a minimum binding score of −7.8 kcal/mol. This compound showed total five hydrogen bonds while two of them were with catalytic residues Asp618 and Asp760. However, another compound, Sitogluside showed a binding score of −7.3 kcal/mol with four hydrogen bonds targeting three functional residues (Arg555, Ser759, and Asp760). Later, 100 ns explicit solvent molecular dynamics (MD) simulation was performed to evaluate the stability of the protein-ligand docked system. These compounds translocated their positions from the catalytic site to the substrate entry site, as observed in the MD simulation trajectory. However, translocation did not affect the binding strength of these compounds, and they retained the strong binding affinity (ΔG < −11.5 kcal/mol), estimated using the MM/GBSA method. In general, the findings of this study indicated the potential therapeutic compounds that may be used targeting SARS-CoV-2 RdRp. However, these compounds still need to be validated by experimentation in order to determine their inhibitory function. Communicated by Ramaswamy H. Sarma

description: Can self-organization of scientific communication be specified by using literature-based indicators? In this study, we explore this question by applying entropy measures to typical "Mode-2" fields of knowledge production. We hypothesized these scientific systems to be developing from a self-organization of the interaction between cognitive and institutional levels: European subsidized research programs aim at creating an institutional network, while a cognitive reorganization is continuously ongoing at the scientific field level. The results indicate that the European system develops towards a stable level of distribution of cited references and title-words among the European member states. We suggested that this distribution could be a property of the emerging European system. In order to measure to degree of specialization with respect to the respective distributions of countries, cited references and title words, the mutual information among the three frequency distributions was calculated. The so-called transmission values informed us that the European system shows increasing levels of differentiation.

The Tasmanian tourist industry the measurement of tourist expenditure
Creators: name: Boyles, RG
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of this dissertion is to investigate the problems of measurement of the value of the Tasmanian tourist industry in terms of gross receipts form tourist expenditure. No attempt is made to derive an estimate of the value of tourist receipts, rather attention is given to the problems of measurement of its various components, namely, the number of tourist visitors, their average lenght of stay and the value of their expenditure. Besides the value of tourist receipts, it was the original intention to present an empiriacal study of other measures of the economic benefits of tourism to Tasmania. However in contemplatinf the usefulness of such a broad study when so little is known about more relevant aspects of the industry, in which case the analysis is presented could only be of a detailed descriptive nature, it was considered more value could be gained from the approach adopted.

description: In order to investigate the relationship between superconductivity and magnetism in bilayer-hydrate cobaltate Na_x(H_3O)_zCoO_2 \cdot yH_2O, Co nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) measurements were performed on three different samples, which demonstrate various ground states at low temperatures. The appearance of small internal fields is observed in the NQR spectra below approximately 6 K on one of the samples that possesses the largest c-axis length and the highest NQR frequency. The other two samples exhibit superconducting transition in zero magnetic field, while these two samples show different ground states in the magnetic fields greater than 5 T. The comparison of the NMR spectra of these two samples obtained in high magnetic fields reveals the appearance of static internal magnetic fields at the Co site below 4 K in the sample that possesses the intermediate c-axis length and the NQR frequency.

description: We propose a model of binary opinion in which the opinion of the individuals change according to the state of their neighbouring domains. If the neighbouring domains have opposite opinions, then the opinion of the domain with the larger size is followed. Starting from a random configuration, the system evolves to a homogeneous state. The dynamical evolution show novel scaling behaviour with the persistence exponent $θ\simeq 0.235$ and dynamic exponent $z \simeq1.02 \pm 0.02$. Introducing disorder through a parameter called rigidity coefficient $ρ$ (probability that people are completely rigid and never change their opinion), the transition to a heterogeneous society at $ρ= 0^{+}$ is obtained. Close to $ρ=0$, the equilibrium values of the dynamic variables show power law scaling behaviour with $ρ$. We also discuss the effect of having both quenched and annealed disorder in the system.

description: Malaria still threatens half the globe population despite successful Artemisinin-based combination therapy. One of the reasons for our inability to eradicate malaria is the emergence of resistance to current antimalarials. Thus, there is a need to develop new antimalarials targeting Plasmodium proteins. The present study reported the design and synthesis of 4, 6 and 7-substituted quinoline-3-carboxylates 9(a–o) and carboxylic acids 10(a–b) for the inhibition of Plasmodium N-Myristoyltransferases (NMTs) using computational biology tools followed by chemical synthesis and functional analysis. The designed compounds exhibited a glide score of −9.241 to −6.960 kcal/mol for PvNMT and −7.538 kcal/mol for PfNMT model proteins. Development of the synthesized compounds was established via NMR, HRMS and single crystal X-ray diffraction study. The synthesized compounds were evaluated for their in vitro antimalarial efficacy against CQ-sensitive Pf3D7 and CQ-resistant PfINDO lines followed by cell toxicity evaluation. In silico results highlighted the compound ethyl 6-methyl-4-(naphthalen-2-yloxy)quinoline-3-carboxylate (9a) as a promising inhibitor with a glide score of −9.084 kcal/mol for PvNMT and −6.975 kcal/mol for PfNMT with IC50 values of 6.58 µM for Pf3D7 line. Furthermore, compounds 9n and 9o exhibited excellent anti-plasmodial activity (Pf3D7 IC50 = 3.96, 6.71 µM, and PfINDO IC50 = 6.38, 2.8 µM, respectively). The conformational stability of 9a with the active site of the target protein was analyzed through MD simulation and was found concordance with in vitro results. Thus, our study provides scaffolds for the development of potent antimalarials targeting both Plasmodium vivax and Plasmodium falciparum. Communicated by Ramaswamy H. Sarma
An investigation of School-Based Curriculum Development in Chinese state-run high schools: A multi-cases study on curriculum leadership and teacher participation

description: This study aims to investigate the implementation of SBCD in high school context of mainland China based on Marsh’s matrix of SBCD variations (1990; 2009). It also investigates the roles and responsibilities of school leaders and teachers in the process of implementation. Most empirical studies in the field have been written in primary and middle school contexts, but few studies were carried out at high schools with a deep consideration of the Chinese University Entrance Examination (UEE). As the fact that UEE has long been deeply embedded in Chinese high school context, little is known about how UEE would affect the implementation of SBCD.A mixed-method design was used to collect and analyse the study data in two state-run high schools of mainland China. The aim of using both quantitative and qualitative data collection tools is to illuminate the way leaders and teachers implement SBCD in a high school, and how they implement and understand the SBCD to afford the existing school structure in relation to the school needs and improvement. Data were collected sequentially according to the explanatory sequential design. In the first phase of the study, a questionnaire was employed to investigate the whole teacher population of two focused schools. In the second phase, 20 participants including leaders and teachers were interviewed through a semi-structured interview. Descriptive statistics and thematic analysis were undertaken.Eight themes with twenty associated sub-themes were identified from the analysis. The findings indicated that the implementation of SBCD mainly depended on the school culture, history and leadership. The results revealed two leader roles and three main responsibilities in leading SBCD, and two different patterns of teacher participation in SBCD such as individual with self-actualisation and passive with a lack of agency. Also, this study confirmed a dilemma of SBCD caused by long-standing traditional exam culture in Chinese state-run high schools.

description: Wimax (Worldwide Interoperability for Microwave Access) is a promising technology which can offer high speed voice, video and data service up to the customer end. The aim of this paper is the performance evaluation of an Wimax system under different combinations of digital modulation (BPSK, QPSK, 4 QAM and 16 QAM) and different communication channels AWGN and fading channels (Rayleigh and Rician). And the Wimax system incorporates Reed Solomon (RS) encoder with Convolutional encoder with half and two third rated codes in FEC channel coding. The simulation results of estimated Bit Error Rate (BER) displays that the implementation of interleaved RS code (255, 239, 8) with two third rated Convolutional code under BPSK modulation technique is highly effective to combat in the Wimax communication system. To complete this performance analysis in Wimax based systems, a segment of audio signal is used for analysis. The transmitted audio message is found to have retrieved effectively under noisy situation.

description: Henry’s law constant data for nitrogen, oxygen, and argon in the ternary liquid mixture water + methanol + ethanol as well as its pure and binary solvent subsystems are reported. The composition and temperature dependence of the Henry’s law constant of the air components in these solutions is investigated by Monte Carlo simulation. The underlying molecular force field models are based on the modified Lorentz–Berthelot combining rules that contain one binary interaction parameter, which is mainly taken from preceding work. Predictions from the molecular models for the pure and binary solutions are convincingly compared to experimental literature data, where available. This finding gives confidence that the Henry’s law constant for the ternary solution is predicted appropriately. On the basis of an extensive molecular simulation data set, correlations are established for the Henry’s law constant between 274.15 and 473.15 K.
Simulation of cottage lot subdivision : a synthesis of social, economic and environmental concerns
Creators: name: Chamber, Alan David
Publisher: name: University of British Columbia
Year: 2011

description: Concern with the inability of traditional measures of value to reflect environmental quality led to this search for another measure to be used in the rapidly developing Gulf Islands of British Columbia. The measure identified, our subjective preference for cottage lots of various sizes, is defined mathematically and compared with the more traditional measures—development cost and market price. A set of 35mm colour slides, all apparently taken from the same cottage porch, were manufactured by superimposing images of various numbers of neighbouring houses on four background scenes. When shown the slides and asked which view they would prefer from their own cottage porch, subjects were found to respond to the number of neighbours and distance to the nearest according to Weber's law. By transforming nearest neighbour distance to a measurement of area, a relationship between subjective preference and lot size is established. To compare the above subjective preference - lot size relationship with more traditional measures of value, a generalized total cost function for cottage lots is built and then tuned with data from the literature. From the total cost function both average and marginal cost equations are derived and plotted for lots of varying size. As might be expected, there is no apparent similarity between subjective preference and development cost for lots of any particular size. With the cooperation of the Provincial Assessor and Registrar of Lands, market price, lot size, date of sale, and other data were collected for 579 parcels of the Gulf Islands. An analysis of this data suggests that, under conditions of very rapid development, the subjective preference - lot size relationship, might be reflected in the market prices. But this traditional measure of value is not a reliable reflection of subjective preference. In an effort to learn some of the conditions under which subjective preferences could be satisfied, a measure of the impact of development upon environmental quality is conceived and incorporated in a mathematical model of the development of the Gulf Islands. Within the model, developers subdivide land in response to demand for cottage lots, their desire for profit, and the cost of producing the lots. The sensitivity of the model to various policy interventions is then tested.
