description: Ixodid ticks (Acari:Ixodidae) are essential vectors of tick-borne diseases in Japan. In this study, we characterized the population genetic structure and inferred genetic divergence in two widespread and abundant ixodid species, Ixodes ovatus and Haemaphysalis flava. Our hypothesis was that genetic divergence would be high in I. ovatus because of the low mobility of their small rodent hosts of immature I. ovatus would limit their gene flow compared to more mobile avian hosts of immature H. flava. We collected 320 adult I. ovatus from 29 locations and 223 adult H. flava from 17 locations across Niigata Prefecture, Japan, and investigated their genetic structure using DNA sequences from fragments of two mitochondrial gene regions, cox1 and the 16S rRNA gene. For I. ovatus, pairwise FST and analysis of molecular variance (AMOVA) analyses of cox1 and 16S sequences indicated significant genetic variation among populations, whereas both markers showed non-significant genetic variation among locations for H. flava. A cox1 gene tree and haplotype network revealed three genetic groups of I. ovatus. One of these groups consisted of haplotypes distributed at lower altitudes (251–471 m.a.s.l.). The cox1 sequences of I. ovatus from Japan clustered separately from I. ovatus sequences reported from China, suggesting the potential for cryptic species in Japan. Our results support our hypothesis and suggest that the host preference of ticks at the immature stage may influence the genetic structure of the ticks. This information may be important for understanding the tick-host interactions in the field to better understand the tick-borne disease transmission and in designing an effective tick control program.

description: Abstract

Purpose: This study aims to examine the influence of third-party logistics providers’ (3PLs) digital transformation maturity on the business performance of pharmaceutical retail stores. Additionally, the study explores the effects of customer orientation and store digital usage on business performance. Store characteristics and inventory models are control variables to mitigate potential confounding effects. Design/Methodology/Approach: A structured survey was conducted among 568 pharmaceutical retail stores to collect data on 3PLs’ digital transformation maturity, 3PLs’ performance, customer orientation, store digital usage, and business performance. Data analysis included correlation analysis, multiple regression analysis, and moderation analysis to assess the relationships between the variables and the potential moderating effects of control variables. Findings: The findings indicate a positive correlation between 3PLs’ digital transformation maturity and performance. High-performing 3PLs demonstrate enhanced supply chain efficiencies and customer service. Moreover, a significant positive association exists between 3PLs’ performance and pharmaceutical retail stores’ business performance. Stores benefit from high-performing 3PLs with improved revenue growth and profitability. Both customer orientation and store digital usage positively impact business performance, increasing customer loyalty and engagement. The control variables, store characteristics, and inventory model moderate the relationships between the variables, accounting for external influences. Practical Implications: This study underscores the significance of 3PLs’ digital transformation maturity and performance in shaping the business performance of pharmaceutical retail stores. Managers and decision-makers should prioritize partnering with digitally mature 3PLs to enhance supply chain efficiency and customer service, resulting in improved business outcomes. Furthermore, adopting customer-centric approaches and embracing digital technologies are essential for enhancing customer engagement and loyalty, ultimately contributing to better financial performance. Originality/Value: This research contributes to understanding the interplay between digital transformation, 3PL performance, and business performance in the pharmaceutical retail sector. The study provides practical implications for industry practitioners, offering valuable insights into optimizing 3PL partnerships and leveraging digital technologies to thrive in a competitive market. Policymakers can use the findings to facilitate the adoption of digital solutions and customer-oriented strategies in the pharmaceutical retail industry.

description: We present and interpret several new X-ray features of the X-ray pulsar PSR J1838-0655. The X-ray data are obtained from the archival data of CHANDRA, RXTE}, and SUZAKU. We combine all these X-ray data and fit the spectra with different models. We find that the joint spectra are difficult to fit with a single power law; a broken power-law model with a break at around 6.5 keV can improve the fit significantly. The photon index changes from $Γ$ = 1.0 (below 6.5 keV) to $Γ$ = 1.5 (above 6.5 keV); this indicates a softer spectral behaviour at hard X-rays. The X-ray flux at 2-20 keV is found to be 1.6x10^{-11} ergs cm^{-2} s^{-1}. The conversion efficiency from the spin-down luminosity is ~ 0.9% at 0.8-10 keV, which is much higher than that (~ 10^{-3}% - 10^{-4}%) of the pulsars that show similar timing properties. We discuss non-thermal radiation mechanisms for the observed high X-ray conversion efficiency and find that emission from the magnetosphere of a greatly inclined rotator is the most favorable interpretation for the conversion rate and the pulse profiles at X-ray bands. A line feature close to 6.65 keV is also detected in the spectra of SUZAKU/XIS; it might be the K$_α$ emission of highly ionised Fe surrounding the pulsar.

description: Vocal production learning, the ability to modify the structure of vocalizations as a result of hearing those of others, has been studied extensively in birds but less attention has been given to its occurrence in mammals. We summarize the available evidence for vocal learning in mammals from the last 25 years, updating earlier reviews on the subject. The clearest evidence comes from cetaceans, pinnipeds, elephants and bats where species have been found to copy artificial or human language sounds, or match acoustic models of different sound types. Vocal convergence, in which parameter adjustments within one sound type result in similarities between individuals, occurs in a wider range of mammalian orders with additional evidence from primates, mole-rats, goats and mice. Currently, the underlying mechanisms for convergence are unclear with vocal production learning but also usage learning or matching physiological states being possible explanations. For experimental studies, we highlight the importance of quantitative comparisons of seemingly learned sounds with vocal repertoires before learning started or with species repertoires to confirm novelty. Further studies on the mammalian orders presented here as well as others are needed to explore learning skills and limitations in greater detail. This article is part of the theme issue ‘Vocal learning in animals and humans’.

description: Three finfish species frequently caught in the waters of the Gulf of
Manfredonia (Apulia, Italy) were studied in order to know how the flesh
composition (proximate, fatty acid, macro- and micro- element contents)
could be affected by the season effect.
The species we examined were European hake (Merluccius
merluccius), chub mackerel (Scomber japonicus) and horse mackerel
(Trachurus trachurus), which were analysed at the raw state in three catch
season and after cooking in two catch season. More precisely, European
hake and chub mackerel caught during winter, summer and fall were
analysed at the raw state. The composition of the flesh of grilled European
hake and chub mackerel was study on fish caught in winter and fall. Horse
mackerel of summer and winter catches were analysed both at the raw
and grilled state. Furthermore, an overall sensory profile was outlined for
each species in two catch season and the relevant spider web diagrams
compared.
On the whole, two hundred and eighty fish were analysed during
this research project in order to obtain a nutritional profile of the three
species. One hundred and fifty was the overall number of specimens used
to create complete sensory profiles and compare them among the
species.
The three finfish species proved to be quite interesting for their
proximate, fatty acids, macro- and micro-element contents. Nutritional and
sensory changes occurred as seasons elapsed for chub and horse
mackerel only. A high variability of flesh composition seemed to
characterise these two species. European hake confirmed its mild sensory
profile and good nutritional characteristics, which were not affected by any
season effect.

description: Machine-generated speech is characterized by its limited or unnatural emotional variation. Current text to speech systems generates speech with either a flat emotion, emotion selected from a predefined set, average variation learned from prosody sequences in training data or transferred from a source style. We propose a text to speech(TTS) system, where a user can choose the emotion of generated speech from a continuous and meaningful emotion space (Arousal-Valence space). The proposed TTS system can generate speech from the text in any speaker's style, with fine control of emotion. We show that the system works on emotion unseen during training and can scale to previously unseen speakers given his/her speech sample. Our work expands the horizon of the state-of-the-art FastSpeech2 backbone to a multi-speaker setting and gives it much-coveted continuous (and interpretable) affective control, without any observable degradation in the quality of the synthesized speech.
Global MHD simulations of stratified and turbulent protoplanetary discs. II. Dust settling

Year: 2009
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: The aim of this paper is to study the vertical profile of small dust particles in protoplanetary discs in which angular momentum transport is due to MHD turbulence driven by the magnetorotational instability. We consider particle sizes that range from approximately 1 micron up to a few millimeters.We use a grid--based MHD code to perform global two-fluid simulations of turbulent protoplanetary discs which contain dust grains of various sizes. In quasi--steady state, the gravitational settling of dust particles is balanced by turbulent diffusion. Simple and standard models of this process fail to describe accurately the vertical profile of the dust density. The disagreement is larger for small dust particles (of a few microns in size), especially in the disc upper layers ($Z>3H$, where $H$ is the scale-height). Here there can be orders of magnitude in the disagreement between the simple model predictions and the simulation results. This is because MHD turbulence is not homogeneous in accretion discs, since velocity fluctuations increase significantly in the disc upper layer where a strongly magnetized corona develops. We provide an alternative model that gives a better fit to the simulations. In this model, dust particles are diffused away from the midplane by MHD turbulence, but the diffusion coefficient varies vertically and is everywhere proportional to the square of the local turbulent vertical velocity fluctuations. The spatial distribution of dust particles can be used to trace the properties of MHD turbulence in protoplanetary discs, such as the amplitude of the velocity fluctuations. In the future, detailed and direct comparison between numerical simulations and observations should prove a useful tool for constraining the properties of turbulence in protoplanetary discs.

description: Using multimodal Magnetic Resonance Imaging (MRI) is necessary for accurate brain tumor segmentation. The main problem is that not all types of MRIs are always available in clinical exams. Based on the fact that there is a strong correlation between MR modalities of the same patient, in this work, we propose a novel brain tumor segmentation network in the case of missing one or more modalities. The proposed network consists of three sub-networks: a feature-enhanced generator, a correlation constraint block and a segmentation network. The feature-enhanced generator utilizes the available modalities to generate 3D feature-enhanced image representing the missing modality. The correlation constraint block can exploit the multi-source correlation between the modalities and also constrain the generator to synthesize a feature-enhanced modality which must have a coherent correlation with the available modalities. The segmentation network is a multi-encoder based U-Net to achieve the final brain tumor segmentation. The proposed method is evaluated on BraTS 2018 dataset. Experimental results demonstrate the effectiveness of the proposed method which achieves the average Dice Score of 82.9, 74.9 and 59.1 on whole tumor, tumor core and enhancing tumor, respectively across all the situations, and outperforms the best method by 3.5%, 17% and 18.2%.

description: The aim of this study is to evaluate the pulmonary function in subjects with diagnosis of Turner Syndrome, in charge at the Syndromology Ward of the Paediatric Clinic of  S.Orsola-Malpighi hospital. There are very few datas about lung function in patients with Turner syndrome’s genotype and phenotype in medical literature. 
Since the thorax of these subjects have peculiar anatomic shape (as “shield” or “overturned triangle”), we presupposed that these subjects could have also a peculiar respiratory function.
Moreover we look for the possibility of correlation between pulmonary function and estroprogestinic replacement therapy and/or growth hormone (GH) replacement therapy.
Material and methods:
we studied  48 patients, with diagnosis of Turner Syndrome; they all made spirometry voluntarily and, when capable, also plethismografy.
Results:
- the parametres of pulmonary function are a little higher of the predicted values for age and sex but they are a little lower if they're corrected for each patient’s ideal high and weight: so we can conclude that in Turner Syndrme subjects pulmonary function is normal;
-there’s not a statistically significant correlation between pulmonary function and GH therapy;
-there’s not a statistically significant correlation between GH therapy’s length and pulmonary function except for Total Lung Capacity which increases with the number of years of GH therapy;
- there’s not a statistically significant correlation between pulmonary function and estroprogestinic replacement herapy.

description: A key feature of vocal ontogeny in a variety of taxa with extensive vocal repertoires is a developmental pattern in which vocal exploration is followed by a period of category formation that results in a mature species-specific repertoire. Vocal development preceding the adult repertoire is often called ‘babbling’, a term used to describe aspects of vocal development in species of vocal-learning birds, some marine mammals, some New World monkeys, some bats and humans. The paper summarizes the results of research on babbling in examples from five taxa and proposes a unifying definition facilitating their comparison. There are notable similarities across these species in the developmental pattern of vocalizations, suggesting that vocal production learning might require babbling. However, the current state of the literature is insufficient to confirm this suggestion. We suggest directions for future research to elucidate this issue, emphasizing the importance of (i) expanding the descriptive data and seeking species with complex mature repertoires where babbling may not occur or may occur only to a minimal extent; (ii) (quasi-)experimental research to tease apart possible mechanisms of acquisition and/or self-organizing development; and (iii) computational modelling as a methodology to test hypotheses about the origins and functions of babbling.

Subjects: BIO/14 Farmacologia

description: Introduction – Although imatinib (IM) is a recognized gold standard in chronic myeloid leukemia (CML) therapy, resistance has emerged in a significant proportion of patients. 
Aim – The aim of this study was: (1) to investigate the role of genetic variants in genes encoding for IM transporters, as candidate of IM responsiveness and (2) to test the influence of miRNAs on IM response, focusing on efflux transporters. 
Methods – As a first step, a panel of polymorphisms (SNPs) was genotyped in a subgroup population of 189 patients enrolled in the Tyrosine Kinase Inhibitor Optimization and Selectivity (TOPS) trial. The association with cytogenetic response and molecular response (MR) was assessed for each SNP. As a second step, an in vitro IM-resistant model (K-562 CML cell line) was established. miRNAs profiles were analyzed using Taqman arrays and in silico search was performed for miRNAs deregulated after IM treatment. mRNA  and protein expression were quantified using TaqMan realtime PCR and Western blotting, respectively. 
Results – (1) Among Caucasian patients, ABCB1 rs60023214 significantly correlated with complete MR (P = 0.005). Concerning SNPs combination in IM uptake transporters, the associations with treatment outcomes were statistically significant for both major and complete MR (P = 0.005 and P = 0.01, respectively). (2) ABCB1 protein was not expressed under any conditions of treatment,  differently from  ABCG2. Two deregulated miRNAs, namely miR-212 and miR-328, were identified to be inversely correlated with ABCG2 (r2= 0.57; p=0.03 and r2=0.47; p=0.06, respectively). Experiments of loss and gain of function confirmed the functional influence of these miRNAs on ABCG2. 
Conclusion – The multiple candidate gene approach identified single and combination of SNPs that can be proposed as predictor of IM response. The in vitro study suggested that IM resistance could be mediated by miRNA-dependent mechanism. Further studies are needed to validate these preliminary findings.

description: Isothermal molecular beam experiments on the methanol oxidation over the stepped Au(332) surface were conducted under well-defined ultra-high vacuum conditions. In the measurements, a continuous flux of methanol at excess in the gas phase and pulses of atomic oxygen were provided to the surface kept at 230 K. The formation of the partial oxidation product methyl formate under the applied conditions was evidenced by time-resolved mass spectrometry, and accumulation of formate species, which resulted in a deactivation of the surface for methyl formate formation, was followed by in situ Infrared Reflection Absorption Spectroscopy measurements. The results suggest a different reactivity of oxygen accumulated during the oxygen pulses and atomic oxygen for the competing reaction pathways in the oxidation of methanol to the desired partial and the unwanted overoxidation products.

description: Abstract

The purpose of the current research is to design a model of the customer's managed online shopping experience in the field of selling digital goods on the Digikala site. The current research is fundamental-applied research in terms of its purpose, and in terms of the method of analysis, it is qualitative research with the grounded glaze method. The approach of the research has been conducted in an inductive way and in terms of time, in a cross-sectional way. The statistical community includes managers and retailers of companies that cooperate with Digikala site in the field of digital products industry. In this regard, a semi-structured interview was conducted with 15 marketing, sales and experts using judgmental and theoretical sampling methods between January and March 2022. In this research, face validity was used to check the validity of the interview questions, and in the coding process, the method of continuous engagement and participation with the research members was used. To check the reliability of the interviews, the test-retest reliability method was used, which was equal to 72.72%, and thus the reliability of the coding was confirmed. In this research, a total of 136 concepts and 42 categories were formed, which were categorized into 4 categories. Each of the 42 categories also affect the management of the actual customer experience based on their positive and negative experiences. Finally, the management of the customer's online shopping experience was presented separately in each of the Voca dimensions. The results showed that in order to improve the customer experience in Voca conditions and reduce negative experiences, it is better for organizations to become agile, smart and transparent, so that on the one hand, they can analyze the dimensions of Voca correctly and on the other hand, at the right time and in the right way according to the conditions.

description: We present high precision radial velocities (RVs) of double-lined spectroscopic binary stars HD78418, HD123999, HD160922, HD200077 and HD210027. They were obtained based on the high resolution echelle spectra collected with the Keck I/Hires, Shane/CAT/Hamspec and TNG/Sarge telescopes/spectrographs over the years 2003-2008 as a part of TATOOINE search for circumbinary planets. The RVs were computed using our novel iodine cell technique for double-line binary stars. The precision of the RVs is of the order of 1-10 m/s. Our RVs combined with the archival visibility measurements from the Palomar Testbed Interferometer allow us to derive very precise spectroscopic/astrometric orbital and physical parameters of the binaries. In particular, we derive the masses, the absolute K and H band magnitudes and the parallaxes. The masses together with the absolute magnitudes in the K and H bands enable us to estimate the ages of the binaries. These RVs allow us to obtain some of the most accurate mass determinations of binary stars. The fractional accuracy in m*sin(i) only and hence based on the RVs alone ranges from 0.02% to 0.42%. When combined with the PTI astrometry, the fractional accuracy in the masses ranges in the three best cases from 0.06% to 0.5%. Among them, the masses of HD210027 components rival in precision the mass determination of the components of the relativistic double pulsar system PSRJ0737-3039. In the near future, for double-lined eclipsing binary stars we expect to derive masses with a fractional accuracy of the order of up to ~0.001% with our technique. This level of precision is an order of magnitude higher than of the most accurate mass determination for a body outside the Solar System - the double neutron star system PSRB1913+16.

description: Abstract

This study is a normative legal research aimed at analyzing and discovering the formulation and model of the central and regional government relations in the equitable management of forest resources using a Philosophical Approach, a Statute Approach, and a Conceptual Approach. The research finds that the formulation and model of central and regional authority in forestry management refer to: a) the principle of subsidiarity, which emphasizes that decisions should be made by the government closest to the affected community; b) the formulation of distributive justice, which underscores the importance of fair distribution of resources; c) the principle of procedural justice, which highlights the importance of participation, transparency, and accountability in decision-making; and d) functional decentralization, which grants greater authority to regional governments in managing forests according to local conditions and the needs of local communities, while maintaining effective coordination with the central government to ensure alignment with national policies. However, functional decentralization also presents challenges, such as ensuring the capacity of regional governments to manage forests effectively and efficiently.

description: We have used a lately established workflow to quantify rhythms of three fish sound types recorded in different areas of the Mediterranean Sea. So far, the temporal structure of fish sound sequences has only been described qualitatively. Here, we propose a standardized approach to quantify them, opening the path for assessment and comparison of an often underestimated but potentially critical aspect of fish sounds. Our approach is based on the analysis of inter-onset-intervals (IOIs), the intervals between the start of one sound element and the next. We calculate exact beats of a sequence using Fourier analysis and IOI analysis. Furthermore, we report on important parameters describing the variability in timing within a given sound sequence. Datasets were chosen to depict different possible rhythmic properties: Sciaena umbra sounds have a simple isochronous—metronome-like—rhythm. The /Kwa/ sound type emitted by Scorpaena spp. has a more complex rhythm, still presenting an underlying isochronous pattern. Calls of Ophidion rochei males present no rhythm, but a random temporal succession of sounds. This approach holds great potential for shedding light on important aspects of fish bioacoustics. Applications span from the characterization of specific behaviours to the potential discrimination of yet not distinguishable species.

The effects will depend on the magnitude of projected land use and climate changes and lake sensitivity to these factors. We used random forests fit with long-term (1971–2016) phytoplankton and cyanobacteria abundance time series, climate observations (1971–2016), and upstream catchment land use (global Clumondo models for the year 2000) data from 14 European and 15 North American lakes basins. We projected future phytoplankton and cyanobacteria abundance in the 29 focal lake basins and 1567 lakes across focal regions based on three land use (sustainability, middle of the road, and regional rivalry) and two climate (RCP 2.6 and 8.5) scenarios to mid-21st century. On average, lakes are expected to have higher phytoplankton and cyanobacteria due to increases in both urban land use and temperature, and decreases in forest habitat. However, the relative importance of land use and climate effects varied substantially among regions and lakes. Accounting for land use and climate changes in a combined way based on extensive data allowed us to identify urbanization as the major driver of phytoplankton development in lakes located in urban areas, and climate as major driver in lakes located in remote areas where past and future land use changes were minimal. For approximately one-third of the studied lakes, both drivers were relatively important. The results of this large scale study suggest the best approaches for mitigating the effects of human activity on lake phytoplankton and cyanobacteria will depend strongly on lake sensitivity to long-term change and the magnitude of projected land use and climate changes at a given location. Our quantitative analyses suggest local management measures should focus on retaining nutrients in urban landscapes to prevent nutrient pollution from exacerbating ongoing changes to lake ecosystems from climate change.

description: Motivated by studies of critical phenomena in the gravitational collapse of vacuum gravitational waves we compare, at the linear level, two common approaches to constructing gravitational-wave initial data. Specifically, we construct analytical, linear Brill wave initial data and compare these with Teukolsky waves in an attempt to understand the different numerical behavior observed in dynamical (nonlinear) evolutions of these two different sets of data. In general, the Brill waves indeed feature higher multipole moments than the quadrupolar Teukolsky waves, which might have provided an explanation for the differences observed in the dynamical evolution of the two types of waves. However, we also find that, for a common choice of the Brill-wave seed function, all higher-order moments vanish identically, rendering the (linear) Brill initial data surprisingly similar to the Teukolsky data for a similarly common choice of its seed function.

description: Abstract

The rapid-fire integration of cloud computing and machine literacy (ML) offers transformative eventuality for enhancing cloud security. Still, this community presents significant challenges and limitations. This paper explores these challenges, including data sequestration enterprises, model interpretability issues, and the complexity of real- time trouble discovery. By analyzing current literature and empirical data, we identify critical areas where ML operations in cloud security are hindered. Our findings punctuate the need for robust encryption styles, transparent ML models, and effective anomaly discovery algorithms. Addressing these issues is pivotal for employing the full eventuality of ML in securing cloud surroundings.

description: Hydrodynamical simulations show that the ram-pressure stripping in galaxy clusters fosters a strong interaction between stripped interstellar medium (ISM) and the surrounding medium, with the possibility of intracluster medium (ICM) cooling into cold gas clouds. Exploiting the MUSE observation of three jellyfish galaxies from the GAs Stripping Phenomena in galaxies with MUSE (GASP) survey, we explore the gas metallicity of star-forming clumps in their gas tails. We find that the oxygen abundance of the stripped gas decreases as a function of the distance from the parent galaxy disk; the observed metallicity profiles indicate that more than 40% of the most metal-poor stripped clouds are constituted by cooled ICM, in qualitative agreement with simulations that predict mixing between the metal-rich ISM and the metal-poor ICM.

description: We investigate shock acceleration in a realistic astrophysical environment with density inhomogeneities. The turbulence induced by the interaction of the shock precursor with upstream density fluctuations amplifies both upstream and downstream magnetic fields via the turbulent dynamo. The dynamo-amplified turbulent magnetic fields (a) introduce variations of shock obliquities along the shock face, (b) enable energy gain through a combination of shock drift and diffusive processes, (c) give rise to various spectral indices of accelerated particles, (d) regulate the diffusion of particles both parallel and perpendicular to the magnetic field, and (e) increase the shock acceleration efficiency. Our results demonstrate that upstream density inhomogeneities and dynamo amplification of magnetic fields play an important role in shock acceleration, and thus shock acceleration depends on the condition of the ambient interstellar environment. The implications on understanding radio spectra of supernova remnants are also discussed.

description: We study universality in the electroproduction of vector mesons using a unified nonperturbative approach which has already proved to reproduce extremely well the available experimental data. In this framework, after the extraction of factors that are specific of each vector meson, we arrive at a reduced integrated elastic cross section which is universal. Our calculations suggest a finite infrared behavior for the strong coupling constant.

Factors influencing the use of local parks

description: The growth of large urban centres in Canada, at a time when the availability of leisure is increasing, has invested urban recreation facilities, such as parks, with a special importance. Although much research effort has been directed towards investigating and anlyzing the phenomenon of large scale rural outdoor recreation and park use, very little study has been undertaken on the subject of urban parks. This is ironical since the largest proportion of leisure time is in "small pieces", much of which can only be spent in the vicinity of the home. Also, for a large segment of urban residents such as young mothers, the poor, the old and children, non-urban parks and recreation facilities do not constitute a realistic alternative to local parks. Given the lack of study in the field of urban parks, planners have been forced to rely on planning tools of doubtful geneology and based on arbitrary assumptions. This study attempts to make a preliminary exploration of one element of the urban park system: the local park in a residential setting. It is based on a behavioural approach and analyses the use of local parks by the surrounding residents in order to ascertain the relationship between the physical variables (characteristics of parks) and the activity and population variables (the use of parks and the users of parks). The hypothesis guiding this study is as follows: The use of local parks is influenced by the physical characteristics of the parks and the population characteristics of the local area residents. The variables examined in detail are: size of park, facilities, supervision, accessibility of the park, on the one hand, and the frequency of park use, the activities conducted in the parks, the characteristics of the park users and their recreational preferences, on the other. A questionnaire survey was conducted in a single family, working class district of Vancouver. The analysis of data from the survey, generally speaking, indicated that the physical characteristics do play a part in the use of local parks. Facilities, supervision and accessibility of the parks emerge as important factors affecting the use of local parks. In the final chapter, the data analysis noted above is extended in order to construct a list of findings which are stated in the form of detailed, tentative hypotheses. The chapter concludes with suggestions to change the method employed in arriving at local park standards. It is recommended that these be based on the notion of an activity space index rather than on land area of the park. This method, it is indicated, would quantify the more functional and significant aspects of local park system than that based on park area.

description: Abstract

Due to the high expense of synthetic medications and the emergence of synthetic antibiotic resistance, many diseases have emerged. Ziziphus jujuba leaf extracts, both aqueous and ethanolic, have demonstrated antibacterial efficacy against Enterococcus faecalis bacterium. Separate ethanol and aqueous extracts were obtained from leaves for demonstration of phytochemical examination of Z. jujuba leaves by using the standard methodology for qualitative analysis of active components and it shows highly significant results. The presence of active components was quantitatively examined using GC/MS analysis. Using the agar well diffusion method, the zone of inhibition was examined using a pure culture of Enterococcus faecalis. The Minimum Inhibitory Concentration was obtained using the Broth Dilution Method. Every analysis was performed three times, and the means of the results were displayed. Natural plant (Ziziphus jujuba) leaf extracts are beneficial against bacterial infections which caused by Enterococcus faecalis.
