Abstract:

The species status of Hyphydrus anatolicus Guignot, 1957 and H. sanctus Sharp, 1882, previously often confused with the widespread H. ovatus (Linnaeus, 1760), are tested with molecular and morphological characters. Cytochrome c oxidase subunit 1 (CO1) was sequenced for 32 specimens of all three species. Gene-trees were inferred with parsimony, time-free bayesian and strict clock bayesian analyses. The GMYC model was used to estimate species limits. All three species were reciprocally monophyletic with CO1 and highly supported. The GMYC species delimitation analysis unequivocally delimited the three species with no other than the three species solution included in the confidence interval. A likelihood ratio test rejected the one-species null model. Important morphological characters distinguishing the species are provided and illustrated. New distributional data are given for the following species: Hyphydrus anatolicus from Slovakia and Ukraine, and H. aubei Ganglbauer, 1891, and H. sanctus from Turkey.

Abstract:

Woodroaches from the genus Cryptocercus Scudder, 1862 are known to display low levels of morphological divergence, yet significant genetic divergence and variability in chromosome number. Compared with Cryptocercus taxa from North America, the diversity of the genus in Asia has received relatively little attention. We performed morphological and karyotypic examinations of multiple taxa from several previously unsampled mountainous areas of central and south-western China, and identified nine candidate species primarily on the basis of chromosome number. We then investigated diversity across all Asian Cryptocercus, through phylogenetic analyses of 135 COI sequences and 74 28S rRNA sequences from individuals of 28 localities, including species delimitation analysis in General Mixed Yule Coalescent (GMYC) and Automatic Barcode Gap Discovery (ABGD). Phylogenetic results indicated that individuals from the same locality constituted well supported clades. The congruence of GMYC and ABGD results were in almost perfect accord, with 28 candidate species described on the basis of karyotypes (including the nine identified in this study). We provide evidence that each valley population in the Hengduan Mountains contains a separate evolving lineage. We conclude that the principal cause of the rich Cryptocercus diversity in China has been the uplift of the Qinghai-Tibet Plateau.

Abstract:

Epeorus (Caucasiron) turcicus sp. nov. is described based on larvae from NE Turkey. The new species can be distinguished from other Caucasiron by a unique combination of several diagnostic characters: the presence of a rounded hypodermal medial femur spot, colouration of abdominal terga and sterna, narrow gill plate VII, fine hair-like setae on the surface of abdominal terga, and absence of postero-lateral projections on tergum X. In addition to morphological analysis, two single-locus analytical approaches are employed for delimiting the new species using COI sequences (Automatic Barcode Gap Discovery, ABGD; and General Mixed Yule Coalescent Model, GMYC). Both approaches unambiguously recognized E. (C.) turcicus sp. nov. as a distinct species. Our molecular dataset contains all Caucasiron species occurring in the Caucasus and the delimitation of individual species mostly follows the morphologically defined species. This study confirms the suitability of the GMYC approach for species delimitation within Caucasiron.

Abstract:

Cyclommatus scutellaris Möllenkamp, 1912, Cyclommatus elsae Kriesche, 1921 and Cyclommatus tamdaoensis Fujita, 2010 are East Asian stag beetle species with long-debated taxonomic relationships due to high intraspecific morphological variability. In this study, we applied multilocus phylogenetic analyses to reassess their relationships. Two mitochondrial genes (16S rDNA, COI) and two nuclear genes (28S rDNA, Wingless) were used to reconstruct the phylogeny through the Bayesian inference (BI) and Maximum Likelihood (ML) methods. Both topologies supported two clades: the clade C. scutellaris was sister to the clade (C. elsae + C. tamdaoensis) with the subclade C. tamdaoensis embedded in the subclade C. elsae. The Kimura 2-parameter (K2P) genetic distance analysis yielded a low mean value (≤0.035) among the three taxa, which was well below the minimum mean value between other Cyclommatus species (≥0.122). We also compared the accuracy and efficiency of two approaches, GMYC and ABGD, in delimitating the three lineages. The result shows that ABGD is a better approach than GMYC. Our molecular data recognizes the three species as different populations of a single species, ranging from Taiwan Island to the continent. Therefore, we propose two new junior synonyms for C. scutellaris: C. tamdaoensis, syn. nov. and C. elsaesyn. nov.

Abstract:

AbstractThe soft scales (Hemiptera: Coccoidea: Coccidae) are a group of sap-sucking plant parasites, many of which are notorious agricultural pests. The quarantine and economic importance of soft scales necessitates rapid and reliable identification of these taxa. Nucleotide sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene (barcoding region) and 28S rDNA were generated from 340 individuals of 36 common soft scales in China. Distance-based [(best match, Automated Barcode Gap Discovery (ABGD)], tree-based (neighbor-joining, Bayesian inference), Klee diagrams, and general mixed Yule coalescent (GMYC) models were used to evaluate barcoding success rates in the data set. Best match showed that COI and 28S sequences could provide 100 and 95.52% correct identification, respectively. The average interspecific divergences were 19.81% for COI data and 20.38% for 28S data, and mean intraspecific divergences were 0.56 and 0.07%, respectively. For COI data, multiple methods (ABGD, Klee, and tree-based methods) resulted in general congruence with morphological identifications. However, GMYC analysis tended to provide more molecular operational taxonomic units (MOTUs). Twelve MOTUs derived from five morphospecies (Rhodococcus sariuoni, Pulvinaria vitis, Pulvinaria aurantii, Parasaissetia nigra, and Ceroplastes rubens) were observed using the GMYC approach. In addition, tree-based methods showed that 28S sequences could be used for species-level identification (except for Ceroplastes ceriferus – Ceroplastes pseudoceriferus), even with low genetic variation (<1%). This report demonstrates the robustness of DNA barcoding for species discrimination of soft scales with two molecular markers (COI and 28S) and provides a reliable barcode library and rapid diagnostic tool for common soft scales in China.

Abstract:

We investigated species diversity and distribution patterns of the marine red alga Portieria in the Philippine archipelago. Species boundaries were tested based on mitochondrial, plastid and nuclear encoded loci, using a general mixed Yule-coalescent (GMYC) model-based approach and a Bayesian multilocus species delimitation method. The outcome of the GMYC analysis of the mitochondrial encoded cox 2-3 dataset was highly congruent with the multilocus analysis. In stark contrast with the current morphology-based assumption that the genus includes a single, widely distributed species in the Indo-West Pacific ( Portieria hornemannii ), DNA-based species delimitation resulted in the recognition of 21 species within the Philippines. Species distributions were found to be highly structured with most species restricted to island groups within the archipelago. These extremely narrow species ranges and high levels of intra-archipelagic endemism contrast with the wide-held belief that marine organisms generally have large geographical ranges and that endemism is at most restricted to the archipelagic level. Our results indicate that speciation in the marine environment may occur at spatial scales smaller than 100 km, comparable with some terrestrial systems. Our finding of fine-scale endemism has important consequences for marine conservation and management.

Abstract:

Nearly 450 Margattea specimens were collected from 27 locations in China and their morphology was examined. Then 68 Margattea COI sequences were obtained and used to carry out phylogenetic analyses as well as species delimitation analyses using General Mixed Yule Coalescent (GMYC), Automatic Barcode Gap Discovery (ABGD), and Poisson Tree Processes (bPTP). GMYC analysis resulted in 21 molecular operational taxonomic units (MOTUs) (confidence interval: 20–22), which was completely consistent with the result of the bPTP. There were 15 MOTUs using the ABGD method. The number of MOTUs was slightly different from the assigned morphospecies (16). As to the incongruence between molecular and morphological results, we checked the specimens again and made sure that most morphological differences were determined to be intraspecific differences (except the difference between M. angusta and M. mckittrickae), although a large genetic distance existed. Finally, 16 Margattea species from China were defined in this study, of which, seven new species are established, i.e. Margattea deltodonta J-J He &amp; Z-Q Wang, sp. nov., Margattea cuspidata J-J He &amp; Z-Q Wang, sp. nov., Margattea caudata J-J He &amp; Z-Q Wang, sp. nov., Margattea paratransversa J-J He &amp; Z-Q Wang, sp. nov., Margattea disparilis J-J He &amp; Z-Q Wang, sp. nov., Margattea transversa J-J He &amp; Z-Q Wang, sp. nov., and Margattea bicruris J-J He &amp; Z-Q Wang, sp. nov.

Abstract:

Chaitophorinae aphids are widespread across Eurasia and North America, and include some important agricultural and horticultural pests. So, accurate rapid species identification is very important. Here, we used three mitochondrial genes and one endosymbiont gene to calculate and analyze the genetic distances within different datasets. For species delimitation, two distance-based methods were employed, threshold with NJ (neighbor-joining) and ABGD (Automatic Barcode Gap Discovery), and two tree-based approaches, GMYC (General Mixed Yule Coalescent) and PTP (Poisson Tree Process). The genetic interspecific divergence was clearly larger than the intraspecific divergence for four molecular markers. COI and COII genes were found to be more suitable for Chaitophorinae DNA barcoding. For species delimitation, at least one distance-based method combined with one tree-based method would be preferable. Based on the data for Chaitophorus saliniger and Laingia psammae, DNA barcoding may also reveal geographical variation.

Abstract:

Background: Reaction time is required for a muscular reaction to start after an administered stimulus (RT). RT assesses the pace at which the central nervous system analyses sensory information and executes it as a motor response. Our bodies react to various sorts of stimuli at varying rates. It is crucial to have this on hand for everyday and emergencies. Several factors, including gender, age, physical fitness, exhaustion, distraction, and alcohol, have impacted reaction time. This visual and aural reaction time area merits more investigation, specifically the impact of object colour (red), acoustic stimulation (beep tone), and gender. Aims and Objectives: 1) To compare medical students' simple visual and auditory reaction times to red colour and beep tone. 2) To compare female and male medical students' simple visual and auditory reaction times. Materials and Methods: After gaining ethical approval (IEC/GMC/Cat-C/2021/531 dated 24/05/2021) and signing informed consent, all 250 (125 women and 125 men divided into two groups) first-year medical students from the cohort of 2020-21 aged 17 to 20 were selected. Anand Agencies Pune developed RT equipment to record VRT and ART. The data were analysed with the SPSS 26.0 statistical program and the unpaired t-test. Results: Study participants showed a statistically significant difference in their VRT for Red (R) and ART for Tone (T), respectively, with 0.199±0.033 seconds and 0.082±0.009 seconds (p < 0.001). As an added benefit, the variance of men's VRT was substantially more significant than that of women's VRT (p = 0.001), with a mean of 0.192±0.026 seconds for men and 0.206±0.037 seconds for women. In contrast, ART had no discernible gender difference (p=0.246). Conclusion: Our analysis revealed that the VRT for red was substantially higher than the ART for tone. This might be because the visual processing time is longer than the audio. Men also respond faster to VRT than women, although their responses to ART are considerably quicker or equivalent to those of women, which explain why these gender disparities occur

Abstract:

Abstract The personal pronouns in the IE languages show a bewildering variety of forms. The similarities are obvious, but the precise paradigms of the parent speech are very difficult to reconstruct. Even a full-blown grammar of PIE would be all but overwhelmed by a discussion of everything at stake. What are given as PIE forms here, therefore, are not always explained or defended, and are to be taken as points of departure for certain sets of correspondences, with more or less extensive remodeling that can be only briefly outlined. Even this elegant analysis leaves loose ends. It envisions a surprising position of the particle in PIE *ei,-om: in PIE, *ge, *i,a, like deictic particles in general, typically follow the modified element-seemingly, in clause-initial position were obliged to (Wackerna gel’s Law, 87 fn.)--as is the case with G j’E, PGmc. *mek, *j,ek, and the usual analysis of Ved. ahrim. Moreover, an analysis which does away with suppletion is not (for once) at tractive per se: suppletion, particularly in the nom. forms of PIE pronouns, is the rule (361, 374.1). Nor under this analysis is PGmc. *ek ‘I’ instead of xeka any less puzzling than before, though one possibility for rescue is the surmise of an early remodeling after *mek and *j,ek. Older Hitt. u-uk, later u-ug-ga are not conspicuously in harmony with the analy sis. Finally, a pronominal particle *-jjm is in any case otherwise needed for Ved. idtim ‘it’ (= L id plus *-om), iytim ‘she’ (*iH2-6m), and for Gmc. *-om in *j,atii ‘that’, *hitii ‘it’, *hwatii ‘what’, seen in Go j,ata, hita, OE hwtl/t.

Abstract:

Hemostasis is the process through which bleeding stops on its own. To assess the overall health of hemostatic systems, bleeding (BT) and clotting time (CT) is used. An assessment of hemostasis must precede each surgical procedure in a hospital. A BT or CT is necessary for epistaxis, hemoptysis, gastrointestinal, and variceal bleeding. On the other hand, these have a role in thrombotic risk and cardiovascular disease. As a result, the researchers in this study set out to see if there were any variations in bleeding and clotting times between young boys and girls. Aims and Objectives: To establish gender disparities in BT and CT among young medical students and examine any correlation between the parameters. Materials and Methods: This cross-sectional survey was carried out between September 2021 and December 2021 in the haematology lab at GMC Jammu's Department of Physiology after receiving IEC permission (Vide No. IEC/GMC/Cat C/2021/532 dated 24/05/2021) and informed consent, involved 250 healthy first-phase MBBS students (17-20 years old) from both genders. According to established protocols, CT and BT were evaluated using Wright's Capillary tube and Duke's filter paper method. Average BT and CT values for male and female medical participants were assessed. All data were reported as Mean with Standard Deviation. We used unpaired t-test analysis with the help of the SPSS 26.0 version to look for BT and CT measurement discrepancies. The Chi-square test did further research to examine any correlation between the parameters. A p-value less than five per cent was deemed statistically significant. Results: In the current research, BT mean values were 2.28 ±0.63 minutes in men and 2.42 ±0.59 minutes in women. In the end, the p-value was found to be 0.066. CT values were 4.61 ±1.22 minutes for men and 5.10 ±1.57 minutes for women, a statistically significant difference (p=0.006). BT and CT appear to be influenced by gender. Conclusion: In our study, the comparison of gender to bleeding and clotting times in agematched participants reveals that females had slightly greater BT and CT values than males. The lower hematocrit and the effects of estrogen with lower fibrinogen levels in women may account for the more prolonged BT and CT, respectively

Abstract:

You have decided on the area you wish to research, reviewed the relevant literature, and developed a research question; your next task is to decide what method is most appropriate to address that question. The first issue you need to consider is whether your study is research or audit. This is important as research and audit, while similar in many respects, have a number of differences that have important ethical, methodological, and management implications. The vogue for ‘call this research project an audit and we don’t need ethics’ is thankfully passing, due not least to intolerance by the General Medical Council (GMC) and National Health Service (NHS) disciplinary panels of such slippery practice. A second issue is broadly methodological, and concerns whether you intend to use quantitative or qualitative methods. Finally, you need to consider whether your research can be done in a clinical setting or is better suited to laboratory conditions, which will have important implications for the manner in which you approach your study. We begin the chapter by considering service investigation and audit and will examine how audit differs from research. Following this we consider quantitative and qualitative approaches and examine their philosophical underpinnings, methods and analysis. Finally we examine basic science concepts and laboratory-based research. For any clinician the main priority in service investigation is the process of auditing one’s own practice. There are, however, other means of evaluating practice. This section will focus in on the assessment of service quality. This, as it turns out, is rather difficult to define. The Department of Health (DoH; 1) defi ne quality as ‘doing the right things, at the right time, for the right people and doing them right — first time’. This, as you may notice, is a rather broad definition which may be of limited value to you when you are planning to use the concept of quality as the central theme of your investigation. However, as this concept of quality is at the centre of pretty much every document the DoH publishes, it is worth keeping it in mind.

Abstract:

Ethics, or moral philosophy, is an attempt to define principles that govern how people should behave in society. Healthcare is practised within communities and must reflect the cultural and ethical values of society as a whole. Professional codes of ethics are not unique to healthcare, but from as early as the 5th century BC ethical behaviour has been acknowledged as a cornerstone of good medical practice. The relationship between a health professional and a patient is one where power lies predominantly with the health professional and the various biomedical ethical codes seek, among other things, to redress that balance. Underpinning all of biomedical ethics are four main principles or shared moral beliefs first articulated by Beauchamp and Childress in the 1970s:<sup>1</sup> Respect for autonomy of the individual. Non-malfeasance (do no harm). Beneficence (do good). Justice (fairness and equality).In some situations the principles can be opposing and each health professional must decide on the right course of action in those circumstances and be accountable for their decision. Material is available to help deal with such dilemmas and in the UK both the General Medical Council (GMC)<sup>2</sup> and the British Medical Association (BMA)<sup>3</sup> produce comprehensive guidance. Cultural and societal differences can lead to varied views on what is ethically acceptable and global guidance issued by bodies such as the World Medical Association<sup>4</sup> is particularly useful as people become more mobile internationally. The issues in occupational health (OH) may differ from those in other branches of healthcare but the same four principles apply. A therapeutic relationship is uncommon in OH and blanket use of the term ‘patient’ in describing ethical duties may therefore be unhelpful since it may lead healthcare professionals and/or those to whom they are rendering services to believe that ethical guidance does not apply to much of their work. Internationally the term ‘worker’ is used much more widely in ethical guidance and this is the terminology that will be used throughout this chapter, whether or not a therapeutic relationship exists. In practice, the ethical challenges and reasoning that should be applied are essentially the same, whether the relationship is a therapeutic one or not, since the power predominantly lies with the OH professional. A worker is far more likely to divulge confidential information to a member of the OH team than to a lay person and management is far more likely to accept guidance on health matters from an OH professional than from someone without a healthcare qualification. OH practitioners enjoy the authority and the status of their core professions—they must therefore apply the same ethical principles as their peers in other specialties. Ethical guidance in OH has tended to be produced at national level, by and for individual professional groups within the discipline.<sup>5,6</sup> This has its benefits but does not reflect well the multidisciplinary nature of most OH teams or the increasing globalization of the workforce. The International Commission on Occupational Health (ICOH) has produced a code of ethics<sup>7</sup> that applies to all OH professionals and which is particularly helpful for those with international responsibilities. There is sometimes confusion between acting ethically and acting lawfully. They are not the same. Laws sometimes allow health professionals to opt out on ethical or moral grounds (e.g. termination of pregnancy). Where that is not the case practitioners should reflect carefully, consult with appropriate colleagues and follow their conscience in full knowledge of any potential consequences for themselves of breaking the law. Simple legal compliance does not guarantee ethical behaviour and acting ethically may be unlawful. The hallmark of a professional is taking responsibility for one’s own actions and acting with probity—that may be difficult but the application of sound ethical analysis can ease the process.

Abstract:

In using process, joints and fasteners always became the weakest area around holes and easy to generate initial damage. At current study, glass chopped fiber mat and unsaturated polyester were used to fabricate glass mat composite (GMC) plates. The influence of open-hole on mechanical property was investigated from tensile test. The decreasing ratio of notched strength from unnotched strength was compared with different size of holes to evaluate the influence of holes size on the sensitivity of GMC. Two sizes of drills, were employed to make drilling hole on the materials. Different damage areas in notched specimens were distinguished. Finally, in order to describe the property of GMC in resistance on open holes, the concept of characteristic distance was introduced. The values were calculated by finite element analysis software (MSC-Marc.) in linear elastic method. Furthermore, the characteristic distance was found that it had a good correspondence with damage characteristics.

Full text

Abstract:

This document is the final project report of the Next Generation Attenuation for Central and Eastern North America (CENA) project (NGA-East). The NGA-East objective was to develop a new ground-motion characterization (GMC) model for the CENA region. The GMC model consists of a set of new ground-motion models (GMMs) for median and standard deviation of ground motions and their associated weights to be used with logic-trees in probabilistic seismic hazard analyses (PSHA). NGA-East is a large multidisciplinary project coordinated by the Pacific Earthquake Engineering Research Center (PEER), at the University of California. The project has two components: (1) a set of scientific research tasks, and (2) a model-building component following the framework of the “Seismic Senior Hazard Analysis Committee (SSHAC) Level 3” (Budnitz et al. 1997; NRC 2012). Component (2) is built on the scientific results of component (1) of the NGA-East project. This report documents the tasks under component (2) of the project. Under component (1) of NGA-East, several scientific issues were addressed, including: (a) development of a new database of ground motion data recorded in CENA; (b) development of a regionalized ground-motion map for CENA, (c) definition of the reference site condition; (d) simulations of ground motions based on different methodologies; and (e) development of numerous GMMs for CENA. The scientific tasks of NGA-East were all documented as a series of PEER reports. The scope of component (2) of NGA-East was to develop the complete GMC. This component was designed as a SSHAC Level 3 study with the goal of capturing the ground motions’ center, body, and range of the technically defensible interpretations in light of the available data and models. The SSHAC process involves four key tasks: evaluation, integration, formal review by the Participatory Peer Review Panel (PPRP), and documentation (this report). Key tasks documented in this report include review and evaluation of the empirical ground- motion database, the regionalization of ground motions, and screening sets of candidate GMMs. These are followed by the development of new median and standard deviation GMMs, the development of new analyses tools for quantifying the epistemic uncertainty in ground motions, and the documentation of implementation guidelines of the complete GMC for PSHA computations. Appendices include further documentation of the relevant SSHAC process and additional supporting technical documentation of numerous sensitivity analyses results. The PEER reports documenting component (1) of NGA-East are also considered “attachments” to the current report and are all available online on the PEER website (https://peer.berkeley.edu/). The final NGA-East GMC model includes a set of 17 GMMs defined for 24 ground-motion intensity measures, applicable to CENA in the moment magnitude range of 4.0 to 8.2 and covering distances up to 1500 km. Standard deviation models are also provided for site-specific analysis (single-station standard deviation) and for general PSHA applications (ergodic standard deviation). Adjustment factors are provided for consideration of source-depth effects and hanging-wall effects, as well as for hazard computations at sites in the Gulf Coast region.

Abstract:

The purpose of this report is to provide a set of ground motion models (GMMs) to be considered by the U.S. Geological Survey (USGS) for their National Seismic Hazard Maps (NSHMs) for the Central and Eastern U.S. (CEUS). These interim GMMs are adjusted and modified from a set of preliminary models developed as part of the Next Generation Attenuation for Central and Eastern North-America (CENA) project (NGA-East). The NGA-East objective was to develop a new ground-motion characterization (GMC) model for the CENA region. The GMC model consists of a set of GMMs for median and standard deviation of ground motions and their associated weights in the logic-tree for use in probabilistic seismic hazard analysis (PSHA). NGA-East is a large multidisciplinary project coordinated by the Pacific Earthquake Engineering Research Center (PEER), at the University of California, Berkeley. The project has two components: (1) a set of scientific research tasks, and (2) a model-building component following the framework of the “Seismic Senior Hazard Analysis Committee (SSHAC) Level 3” [Budnitz et al. 1997; NRC 2012]. Component (2) is built on the scientific results of component (1) of the NGA-East Project. This report does not document the final NGA-East model under (2), but instead presents interim GMMs for use in the U.S. Geological Survey (USGS) National Seismic Hazard Maps. Under component (1) of NGA-East, several scientific issues were addressed, including: (a) development of a new database of empirical data recorded in CENA; (b) development of a regionalized ground-motion map for CENA, (c) definition of the reference site condition; (d) simulations of ground motions based on different methodologies, (e) development of numerous GMMs for CENA, and (f) the development of the current report. The scientific tasks of NGA- East were all documented as a series of PEER reports. This report documents the GMMs recommended by the authors for consideration by the USGS for their NSHM. The report documents the key elements involved in the development of the proposed GMMs and summarizes the median and aleatory models for ground motions along with their recommended weights. The models presented here build on the work from the authors and aim to globally represent the epistemic uncertainty in ground motions for CENA. The NGA-East models for the USGS NSHMs includes a set of 13 GMMs defined for 25 ground-motion intensity measures, applicable to CENA in the moment magnitude range of 4.0 to 8.2 and covering distances up to 1500 km. Standard deviation models are also provided for general PSHA applications (ergodic standard deviation). Adjustment factors are provided for hazard computations involving the Gulf Coast region.

Abstract:

The Bank defines Global Multisector Credit Operations (GMCs) as loans with sovereign guarantees granted to intermediary financial institutions or similar agencies to enable them to on-lend to sub-borrowers for the financing of multisector projects. This evaluation (RE-336) is based on a detailed analysis of the GMCs approved between 1990 and 2005. About two-thirds of the GMCs -representing 82% of the approved GMC funding- were reviewed in-depth and involved fieldwork in the respective countries. The remaining GMCs were desk-reviewed via Project Reports, Portfolio Performance Monitoring Reports, Credit Regulations, Project Completion Reports, and any other available document, e.g. ad hoc consultant studies OVE complemented the evaluation with surveys and interviews providing both Bank staff and clients with an opportunity to participate.
