Investigation of spider web oriented composite fabrics burst strength

Burst strength is a significant property that determines all other properties of structures to perform under induced internal pressure. In this study, the burst strength of a spider web-formed fabric structure is experimentally investigated. The spider web form orientation is prepared using Embroidery machine. A spider web develops a self-stressing nature, which offers its excellent inelasticity and provides a mechanism for competent and economical means to harmonize the local and global induced stresses in their structure. The obtained results are compared with published works on different effects of fiber architectures. The burst test result on spider web form indicated a spider web form's potential candidacy to utilize it as a future fiber orientation technique to form an enhanced composite reinforcement. However, fiber orientation influences the fiber-reinforced composite's mechanical properties. Fiber orientation via spider web form has not yet been used as a reinforcing engineering composite product. Hence, conducting rigors experimental work on spider web form reinforced composite structures can be taken as a significant step to fill the research gap.

Cooperative Carrier Phase Positioning for Asynchronous Narrowband Positioning Systems

Carrier phase positioning (CPP) is crucial for precise positioning in Global Satellite Navigation Systems and has gradually been applied to ground-based narrowband positioning systems such as cellular networks and pseudolites. Existing research mainly focuses on single point positioning (SPP) or double difference positioning (DDP) modes. SPP is non-cooperative, and DDP is considered to be a dual-user cooperation requiring the deterministic model of a static reference station. In this paper, we develop a cooperative CPP (CoCPP) mode for asynchronous systems. CoCPP enables multi-user cooperation and allows both static and mobile users to participate in the cooperation. Specifically, we present the principle and algorithm of CoCPP and discuss practical considerations associated with the test of ambiguity fixing. CoCPP makes the carrier phase ambiguities become integers by double differencing and then enables cooperation gains based on ambiguity fixing. We prove that CoCPP has lower Cramer-Rao Lower Bound than SPP if the ambiguities are correctly fixed. We demonstrate that the single difference matrices and cooperating sequences are non-trivial in the case of partial ambiguity fixing for CoCPP. Simulations show that CoCPP outperforms SPP in positioning accuracy.
Reducing the Incidence of Compassion Fatigue in Obstetrical Nurses

Practice Problem Compassion fatigue is a growing problem that can affect 21% to 39% of nurses who work in hospital settings (Berger et al., 2015). Compassion fatigue has been further exacerbated due to the COVID-19 pandemic. Compassion fatigue negatively impacts the nurses in profound physical and emotional ways. PICOT The PICOT question that guided this project was: For obstetrical nurses working in a nonprofit organization, what is the effect of a compassion fatigue program, compared with no program, on nurses in reducing compassion fatigue after two months? Evidence Current evidence shows that mindfulness decreases compassion fatigue and increases compassion satisfaction. Intervention This paper describes how a mindfulness program was implemented in obstetrical unit in a nonprofit hospital in central Virginia. Outcome The implementation of this mindfulness program has resulted in a 15.6% increase in compassion satisfaction, a 35.1% decrease in burnout, and a 39.5% decrease in secondary traumatic stress. Conclusion This EBP project demonstrated that the mindfulness program successfully decreased the incidence of compassion fatigue in obstetrical nurses at a statistically significant level. REDUCING INCIDENCE OF COMPASSION FATIGUE 3 Reducing the Incidence of Compassion Fatigue in Obstetrical Nurses The term “compassion fatigue” (CF) was first coined in the 1950s in nursing and with other first line responders (Milligan & Almomani, 2020). CF was introduced by Joinson (1992), where she described CF as a unique form of burnout (BO) influencing individuals in care giving careers including pastors, advisors, and particularly nurses. Critical care nurses provide care to highly critical patients and are at higher risk to develop CF (Sacco et al., 2015). This evidence-based practice (EBP) project examines the problem of CF in nurses who work in obstetrical units. The aim of this scholarly project is to reduce the incidence of CF through the implementation of a CF program which increases awareness and compassion satisfaction through practicing mindfulness. This paper discusses the significance of the practice problem; PICOT question; theoretical framework; evidence search strategy and results; themes with practice recommendations; setting, stakeholders, and system change; implementation plan with timeline and budget; evaluation plan; impact; dissemination plan; and conclusion. Significance of the Practice Problem Figley (1995) defined CF as “the natural consequent behaviors and emotions resulting from knowing about a traumatizing event experienced by a significant other, for example, the stress resulting from helping or wanting to help a traumatized or suffering person” (p. 253). CF in nurses is well documented in literature (Hooper et al., 2010; Hunsaker et al., 2015; Mooney et al., 2017; Notle et al., 2017; Wu et al., 2016) and develops gradually from an undesired result of taking care of suffering individuals (Stamm, 1999). Moreover, CF is an emotional and physical fatigue that can be preventable when balanced by compassion satisfaction (Hunsaker et al.,
Word Embeddings-Based Pseudo Relevance Feedback Using Deep Averaging Networks for Arabic Document Retrieval

Pseudo relevance feedback (PRF) is a powerful query expansion (QE) technique that prepares queries using the top k pseudo-relevant documents and choosing expansion elements. Traditional PRF frameworks have robustly handled vocabulary mismatch corresponding to user queries and pertinent documents; nevertheless, expansion elements are chosen, disregarding similarity to the original query’s elements. Word embedding (WE) schemes comprise techniques of significant interest concerning QE, that falls within the information retrieval domain. Deep averaging networks (DANs) defines a framework relying on average word presence passed through multiple linear layers. The complete query is understandably represented using the average vector comprising the query terms. The vector may be employed for determining expansion elements pertinent to the entire query. In this study, we suggest a DANs-based technique that augments PRF frameworks by integrating WE similarities to facilitate Arabic information retrieval. The technique is based on the fundamental that the top pseudo-relevant document set is assessed to determine candidate element distribution and select expansion terms appropriately, considering their similarity to the average vector representing the initial query elements. The Word2Vec model is selected for executing the experiments on a standard Arabic TREC 2001/2002 set. The majority of the evaluations indicate that the PRF implementation in the present study offers a significant performance improvement compared to that of the baseline PRF frameworks.
Prospective Comparison of Osteoporotic Vertebral Fracture Treatment

Thoracolumbar osteoporotic vertebral fractures often occur in elderly patients. Possible treatment options include conservative therapy with orthoses and minimally invasive therapies like balloon kyphoplasty. Studies show advantages in pain reduction post-kyphoplasty. In contrast, activating orthoses seem to have a longer-term positive effect on muscles and thus the sagittal plane of the spine.
Parameterizing Debt Maturity

We examine ways to describe the maturity structure of public debts using few parameters. We compile a novel data set of all promised future payments for U.S. and UK government debt from every month since 1869, and more recently for Peru, Poland, Egypt, and Nigeria. We show there is a unique parametric form which does not arbitrarily restrict debt issuance. We use this model to parsimoniously describe the evolution of public debt maturities and to characterize the relationship between maturity and the term structure of interest rates in the United States since 1940.
Effects of exosomes from human umbilical cord mesenchymal stem cell on cardiac function in rats with dilated cardiomyopathy induced by Adriamycin

Background Dilated cardiomyopathy (DCM) is one of the most common cardiomyopathies in children, but we have no effective method to treat it. In recent years,the application of human umbilical cord mesenchymal stem cell (hucMSC) therapy in DCM has made a great progress, whileits mechanism remains unknown. The paracrine of hucMSCs has attracted attention as the main mechanism. In this study we explore the effect of the human umbilical cord mesenchymal stem cell-derived exosomes (hucMSC-Ex) on the cardiac function in rat models with DCM that is induced by Adriamycin. Methods Sprague-Dawley rats were intraperitoneally injected with Adriamycin to establish aDCM model. HucMSC-Ex were injected through the tail vein in the DCM group and phosphate-buffered saline (PBS) was injected in theDCMcontrolgroup.The rats were monitored for 2 weeks and thecardiac function was evaluated using thecardiac ultrasound.The pathological changes of the myocardium were observed usingimmunohistochemistry. Western blot and real-time fluorescent quantitative PCR were used to detect the expression of Smad3, alpha smooth muscle actin (α-SMA) and I type collagen (COLI)in the myocardial tissue amongthe groups of rats.Finally, the ultrastructure of the myocardium was observed using electron microscopy. High throughput sequencing was performed on the ventricular muscles in each group. Result High-throughput sequencing results show that after the treatment with hucMSC-Ex, the level of myocardial Scn5a in the myocardium significantly increased (P < 0.05). RT-PCR shows that the level of Lmod2 also significantly increased.The expression of Smad3,α-SMA and COL I was reduced(P < 0.05). The inflammation in the myocardial tissue decreased and the mitochondrial swelling was reduced.The left ventricular ejection function (LVEF) and left ventricular fractional shortening (LVFS)in the rats significantly increased (P < 0.05) and the cardiac function was significantly improved (P < 0.05). Conclusion The treatment with hucMSC-Ex through the tail vein can significantly improve thecardiac function and reduce the degree of myocardial fibrosis induced by Adriamycin.
Direct-Virtio: A New Direct Virtualized I/O Framework for NVMe SSDs

Virtualization is a core technology for cloud computing, server consolidation and multi-platform support. However, there is a concern regarding performance degradation due to the duplicated I/O stacks virtualization environments. In this paper, we propose a new I/O framework, we refer to it as Direct-Virtio, that manipulates storage directly, which makes it feasible to avoid the duplicated overhead. In addition, we devise two novel mechanisms, called vectored I/O and adaptive polling, to process multiple I/O requests collectively and to check I/O completion efficiently. Real implementation-based evaluation shows that our proposal can enhance performance for both micro and macro benchmarks.
Species delimitation in Capparis (Capparaceae): Morphological and molecular

Capparis spinosa L. (Capparidaceae) is the largest genus of the family Capparaceae, distributed in pantropical region. C. spinosa is known as a medicinal plant species. In Iran, different parts of caper bush plants are used as diuretics, tonics and in treatment of malaria and joint disease. Till present time, there has been no detailed information available on molecular phylogeny and genetic structure of these species in the country. Therefore, the present study was conducted with the aim to investigate species delimitation by both morphological and molecular data and to reveal genetic diversity and population structure in these five of Capparis species. For this study, 108 randomly collected plants from 20 geographical populations in of Capparis species were used. We encountered extensive within species genetic and morphological diversity. ISSR molecular markers could delimit the studied species. STRUCTURE analysis revealed the occurrence gene flow between these species. The Mantel test showed correlation between genetic distance and geographical distance of the populations studied. Phylogenetic tree was constructed based on ITS data set which separated out-groups from the studied species. Genetic affinity of the studied species have been discussed.
POSTERIOR DE POLYA NO MONITORAMENTO AMOSTRAL DE PESCARIAS

A non-informative bayesian approach to sample-based fishery surveys is proposed. The Polya posterior for finite population parameters is used to obtain the inferences. The viability of a sampling plan was used in a pilot field experiment to collect weekly information about effort and catch from the artisanal fishery in Rio Grande, RS. Based on a simulated virtual population with four species and 345 fishermen, the sampling plan was tested using a sampling fraction of 3.3% from a complete data matrix of 2760 components. Results have shown accuracies above 71% for all but the most problematic species 2, and around 90% for estimates of total catch and cummulative effort. The percentile probability intervals (ICr) perform slightly better than the highest density interval (HDI) in terms of coverage; although both resulted about 5 percentage points bellow the nominal value of 95%.
Calmodulin: The switch button of calcium signaling

Calmodulin (CaM), a calcium sensor, decodes the critical calcium-dependent signals and converts them into the driving force to control various important cellular functions, such as ion transport. This small protein has a short central linker to connect two globular lobes and each unit is composed of a pair of homologous domains (HD) which are responsible for calcium binding. The conformation of each HD is sensitive to the levels of the intracellular Ca2+ concentrations while the flexible structure of the central domain enables its interactions with hundreds of cellular proteins. Apart from calcium binding, posttranslational modifications (PTMs) also contribute to the modulations of CaM functions by affecting its protein-protein interaction networks and hence drawing out the various downstream signaling cascades. In this mini-review, we first aim to elucidate the structural features of CaM and then overview the recent studies on the engagements of calcium binding and PTMs in Ca2+/CaM-mediated conformational alterations and signaling events. The mechanistic understanding of CaM working models is expected to be a key to decipher the precise role of CaM in cardiac physiology and disease pathology.
Relationship between KRAS mutation and diffusion tensor imaging features in brain metastases due to colorectal cancer; preliminary study

Identifying Kirsten rat sarcoma (KRAS) mutation status is important for metastatic colorectal cancer treatment. Validating KRAS mutation profile on neuroimaging without histopathologic analysis would be beneficial. We aimed to differentiate Kirsten rat sarcoma (KRAS) gene mutation profile according to diffusion tensor imaging (DTI) metrics obtained from colorectal brain metastases (CRBM). Total of 8 patients with 17 CRBM included with known KRAS gene mutation status. All patients were categorized into two groups according to the KRAS mutation status as positive (+) (n: 5, 11 lesions) and negative (-) (wild type) (n: 3, 6 lesions). DTI values of the BMs were evaluated by consensus of two radiologists. Apparent diffusion coefficient (ADC), normalized apparent diffusion coefficient (nADC) and fractional anisotropy (FA) values of the two groups were compared. For comparison the Mann-Whitney U test was used. KRAS mutation (+) group showed significantly lower ADC and nADC values on CRBM rather than the wild-type. Comparison of the FA values of the two groups did not reveal any statistical significance. In conclusion, decreased ADC and nADC values of CRBM are correlated with presence of KRAS mutation. Lower ADC and nADC values obtained from CRBM can be utilized to insight KRAS mutation profile.

The performance of the CNN in detecting environmental sounds was analyzed using the parameters that were defined, with an overall accuracy of 96.8%. The result was promising for machine learning that detects sounds that can be applied as technology for an innovative learning environment.
Assuring the Safety of Local and Imported Beef Meat from Different Slaughterhouses in Egypt

| The current study was applied to investigate E. coli and Staph. aureus counts as well as serodiagnosis of E. coli , Salmonellae isolates and determination of enterotoxin production by Staph. aureus in 100 random local and imported fresh beef samples, from different slaughterhouses at Cairo and Giza Governorates. Staph. aureus was isolated from 22(44%) and 20 (40%) of examined local and imported meat samples respectively. E. coli was found in 40 (80%) and 34(68%) in examined local and imported meat samples, respectively. Staph. aureus enterotoxin types (A & D) were detected in two strains out of 5 randomly selected isolates from local meat only (20% of each). E. coli , one strain (20%) was isolated from fresh local meat; and classified as Enteropathogenic (EPEC), while two strains (40%) were Enterohaemorrhagic (EHEC) “O111:H2”, one strain (20%) was Enterotoxigenic (ETEC) “O15:H4”. On the other hand, one strain of E. coli (20%) isolated from imported meat was classified as Enteropathogenic (EPEC) and its serodiagnosis was O128:H2, while one strains (20%) was Enterohaemorrhagic (EHEC) “O26:H11” which harbored both ( stx1 and stx2 ) genes and finally, the 3 rd strain (20%) was Enteroinvasive (EIEC) “O159”. Meanwhile, Salmonella spp . was isolated from two samples (4%) of examined local meat; one strain was identified as S. Montevideo of Group “C1” with antigenic structure (O6,7,14:H g,m,s:1,2,7) and the 2nd strain was S. enteritidis of group “D1” (O: 1,9,12:H g,m). While, imported meat recorded 1 strain (2%) of S. Typhimurium of group “B” (O:1,4,5,12 H: i:1,2). A concerted effort, Hazard Analysis and Critical Control Points (HACCP) should be made to improve sanitary condition to mitigate bacterial contamination in slaughterhouses.
Alterações da macrofauna do solo induzidas pela expansão de cultivo de cana-de-açúcar sobre áreas de pastagem extensiva

Changes in soil macrofauna induced by the expansion of sugarcane cultivation over areas of extensive pasture The sugarcane expansion over extensive pasture areas has been one of the main scenarios for land use change (LUC) in the south-central region of Brazil. However, it is known that LUC can negatively affect soil biodiversity, and the multiple functions and services associated with these organisms. Among the organisms, the macrofauna is fundamental for plant fragmentation, structuring and soil stabilization. herefore, we aim to evaluate changes in the edaphic and epigeic macrofauna, induced by sugarcane expansion cultivation over extensive pasture. For this purpose, LUC chronosequences (synchronic approach) were investigated, including the following uses: i) native vegetation, ii) extensive pasture, ii) newly implanted sugarcane field over pasture area (Sugarcane); and iv) consolidated sugarcane (Sugarcane ratoon), in two locations, one with clayey soil and the other with sandy soil in the state of São Paulo. At the end of the rainy season between March and April 2019, monoliths (25 x 25 x 10 cm) were collected at depths 0-10, 10-20, and 20-30 cm for the assessment of the edaphic macrofauna. To assess the epigeic macrofauna, pitfall traps were installed at each sampling point. The edaphic and epigeic macrofauna composition differed between land uses. The native vegetation had greater abundance of edaphic and epigeic groups. Coleoptera and earthworms were associated with pasture areas, mainly in clayey soil. The analysis of mixed linear effects showed that LUC affected the relative abundance of edaphic macroinvertebrates (Land use p = 0.1191 r marginal = 0.28, r 2 conditional = 0.33) and epigeic (Land use p = 0.0176; r marginal = 0.22, r 2 conditional = 0.32). The vast majority of the edaphic macrofauna was concentrated in the topsoil (0-10 cm) with a reduction in depth (10-20 and 20-30 cm). In general, the abundance and diversity of macrofauna showed a positive correlation for organic matter, carbon and microbial nitrogen, macroporosity and total porosity, and a negative correlation for soil density (p<0.05). This study draws attention to the significant loss of the abundance and diversity of the sugarcane ratoon macrofauna. Given the importance of these organisms for the functioning of the soil and ecosystems, soil management and conservation practices are necessary to maintain the edaphic and epigeic macrofauna in sugarcane areas, and are important for increasing soil quality and sustainability production system.
