Adopting new technology or fighting the competition may not be enough when these critical moments arise. That's because inflection points build up force so quickly that organizations may have a hard time even putting a finger on what has changed. The way a firm responds could propel it to new heights or lead to its demise. Over the last few years, industry has begun developing a model of information technology known as Cloud computing, which includes Software as a Service. This new model has reached an inflection point and will give users the choice to purchase IT as a service, as a complement to, or as a replacement of the traditio
Performance Analysis of Ku/Ka Dual-Band SAR Altimeter from an Airborne Experiment over South China Sea

Satellite radar altimeters have been successfully used for sea surface height (SSH) measurement for decades, gaining great insight in oceanography, meteorology, marine geology, etc. To further improve the observation precision and spatial resolution, radar altimeters have evolved from real aperture to synthetic aperture, from the Ku-band to Ka-band. Future synthetic aperture radar (SAR) altimeter of the Ka-band is expected to achieve better performance than its predecessors. To verify the SAR altimeter data processing method and explore the system advantage of the Ka-band, a Ku/Ka dual-band SAR altimeter airborne experiment was carried out over South China Sea on 6 November 2021. Through dedicated hardware design, this campaign has acquired the Ku and Ka dual-band echo data simultaneously. The airborne data are processed to estimate the SSH retrieval precision after a series of procedures (including height compensation, range migration correction, multi-look processing, waveform re-tracking). To accustom to the airborne experiment design, a SAR echo model that fully considers both the attitude variation of the aircraft and the elliptical footprint of radar beam is established. The retrieved SSH data are compared with the public SSH data along the flight path at the experiment day, showing good consistence for both bands. By calculating the theoretical precision of waveform re-tracking and re-processing the dual-band airborne data into different bandwidths, it is demonstrated that the Ku/Ka precision ratio is possible to achieve 1.4 within the 27 km offshore area, which indicates that Ka-band has better performance.
Motility and Abnormality of Sheep Spermatozoa That is Being Frozen Using Soybean Lecithin (Soybean Lecithin)

The specific purpose of this study was to determine the effect of optimal levels of soybean lecithin in sperm extenders on motility and abnormalities of sheep spermatozoa after undergoing the freezing process. This research was conducted experimentally in a laboratory with a completely randomized design (CRD) with five treatments and three replications. The five treatments tested were soybean lecithin levels in Tris (L) diluent, consisting of: L0 = 0% soybean lecithin + 95% Tris diluent + 5% glycerol; L1 = 1% soy lecithin + 94% Tris diluent + 5% glycerol; L2 = 2% soy lecithin + 93% Tris diluent + 5% glycerol; L3 = 3% soy lecithin + 92% Tris diluent + 5% glycerol; L4 = 4% soy lecithin + 91% Tris diluent + 5% glycerol. The independent variable in this study was the level of soy lecithin in the Tris diluent. The dependent variable is the progressive motility and abnormalities of post-clotting spermatozoa. Soybean lecithin levels had a significantly different effect (P? 0.05) on the percentage of progressive motility and spermatozoa abnormalities of post-freezing sheep. The level of 3% soya bean lecithin is the best level in maintaining the quality of post-freezing sheep spermatozoa.
Sustainable integration of laying hens with crops in organic farming. A review

ABSTRACT Crop-livestock integration plays a key role in the sustainability of organic agriculture systems, where the reduction of inputs is central to farms performance. The existing literature has focused on the general dynamics of crop-livestock systems without exploring the specificities of each animal species. Egg production significantly contributes to the world food market and it is expected to continue due to its versatility. At the same time, consumption of organic products has increased in recent years, due to enhanced consumers’ awareness. This work reviews the complex web of relationships between various elements of organic agriculture systems with integrated laying hens. The major findings about the integration of laying hens with crops in organic systems are as follows: 1) contributes to the reduction of inputs (less feed and fertilizers) and a diversified production; 2) supports ecosystem services shaping the landscape toward biodiversity and contributing to a healthier environment; and 3) improves farmers’ livelihood, especially in developing countries. Its benefits will be increased by using mobile systems to ensure a better distribution of manure and in synchronization with canopy cover species, such as fruit and forest trees. However, more research is needed to find further contributions to this system sustainability.
Evaluation of biochemical parameters in acute myocardial infarction and angina patients

Background: Early and accurate detection of acute myocardial infarction (AMI) is an important unmet clinical requirement. The present study sought to evaluate the levels of N-terminal pro-brain natriuretic peptide (NTproBNP), cardiac troponin I (cTnI), fasting lipid profile, random blood sugar, and serum creatinine in AMI patients compared to angina patients. Methods: In a single-center, hospital-based, cross-sectional, observational, prospective study conducted at Gandhi Medical College, Secunderabad, from October-2018 to September-2019. A total of 150 patients aged above 40 years with acute chest pain (within 2-6 hours) and who were clinically susceptive of AMI and angina were investigated. The patients were divided into group I (50 AMI patients) and group II (100 angina patients). Levels of all biochemical parameters of blood were assessed. The statistical analyses were performed using the SPSS statistical software, version 15. A student t-test was used to compare the continuous variables between the two groups. Results: Out of 150 patients, higher male prevalence was found in both the groups (60% and 63%, respectively). Group I had higher levels of NTproBNP (2909±273pg/ml vs. 110±20.74pg/ml, P<0.01), cTnI (2.06±1.3ng/ml vs. 0.006±0.002ng/ml, P<0.01), and fasting lipid profile (total cholesterol:216±41.2mg/dl vs.201±32.5mg/dl, P<0.05, triglycerides:217.7±63.6 mg/dl vs. 175.3±48.8 mg/dl, P<0.01, low-density lipoprotein:141.7mg/dl±41.5 vs. 127.1±30.24 mg/dl, P<0.05, very low-density lipoprotein:43.4±12.8mg/dl vs. 35.1±9.8mg/dl, P<0.01) than group II, except low levels of high-density lipoprotein (31.2±3.83mg/dl vs. 38.9±4.32 mg/dl, P<0.01). Conclusion: Assessment of NTproBNP, cTnI, and fasting lipid profile may aid in the early diagnosis of AMI and its management.
A Novel Meander Line Metamaterial Absorber Operating at 24 GHz and 28 GHz for the 5G Applications

Fifth generation (5G) communication systems deploy a massive MIMO technique to enhance gain and spatial multiplexing in arrays of 16 to 128 antennas. In these arrays, it is critical to isolate the adjacent antennas to prevent unwanted interaction between them. Fifth generation absorbers, in this regard, are the recent interest of many researchers nowadays. The authors present a dual-band novel metamaterial-based 5G absorber. The absorber operates at 24 GHz and 28 GHz and is composed of symmetric meander lines connected through a transmission line. An analytical model used to calculate the total number of required meander lines to design the absorber is delineated. The analytical model is based on the total inductance offered by the meander line structure in an impedance-matched electronic circuit. The proposed absorber works on the principal of resonance and absorbs two 5G bands (24 GHz and 28 GHz). A complete angular stability analysis was carried out prior to experiments for both transverse electric (TE) and transverse magnetic (TM) polarizations. Further, the resonance conditions are altered by changing the substrate thickness and incidence angle of the incident fields to demonstrate the functionality of the absorber. The comparison between simulated and measured results shows that such an absorber would be a strong candidate for the absorption in millimetre-wave array antennas, where elements are placed in proximity within compact 5G devices.
Handover issues in autonomous driving: A literature review

The present review was undertaken to inform a workpackage of the Venturer Project undertaking studies into the handover of control between a human driver and an autonomous road vehicle. The ‘handover problem’ arises as a feature of the development of autonomous vehicles that are “highly” but not “fully” autonomous (DfT, 2015). As human error is a major cause of road accidents, contributing to over 90% of road collisions, removing the human operator would likely reduce their incidence. (DfT 2015; Reason, Manstead, Stradling, Baxter, & Cambell, 1990). However, levels of automation which do not completely eliminate the role for a driver can themselves provide problems for the human operator (Stanton and Marsden, 1996; Parasuraman & Manzey, 2010; Parasuraman & Riley, 1997), due to required tasks such as ‘handover’. The report considers the existing evidence on handover, identifying research gaps for handover particularly in urban areas, and considers the policy implications.
Factors Influencing Sexual Health Service Use by South Asian Immigrant Men Living in Ontario, Canada: A Qualitative Study

Introduction: South Asian communities comprise one of the fastest-growing populations in Canada, but there is a paucity of research on if and how immigrant men use sexual health services. Objectives: Our study aimed to understand factors influencing sexual health service use by South Asian immigrant men living in Ontario, Canada. Methods: An interpretive description (ID) research methodology was used, followed by Braun and Clarke’s thematic guidelines to collect and analyze data. Altogether, 18 semi-structured interviews were conducted between May and July 2021 with South Asian immigrant men between 20 and 45 years of age in Ontario. Results: We found that culture shaped the overall perception and use of sexual health services, while the perceived severity of sexual illness also affected the utilization of preventative care. Moreover, there are taboos about sexual health, and while sex positivity and sex negativity exist, sexual health information is shared with trusted sources. We also found South Asian men shared sexual health more openly by following a lifestyle that normalizes sexual health discussions rather than South Asian cultural norms. Conclusions: This study provides a comprehensive understanding of the individual, structural and cultural determinants of health influencing sexual health service use to strengthen existing health communication strategies to improve service utilization for diverse communities in Canada.
Capabilities To Customize Production And Reconfigure Internally: Do Capabilities Influence Perceived Operating Performance And Competitive Advantage?, Las Capacidades De La Empresa Para Personalizar Su Produccion Y Reconfigurarse De Forma Interna: Â¿Influencian Su Desempeno Operativo Y Su Ventaja Co

Having the best capacities allows companies to efficiently choose and implement the necessary activities to produce and deliver goods and services to their clients. Nevertheless, if the purpose is to exceed competitor performance, it is necessary for companies to deploy their capabilities in a superior manner. This work analyzes the impact of operational capacities of massive personalization and reconfiguration and competitive dimensions recognized as strategic. We examine how the affect operative development from a productive entity, and the effect of this on perceived competitive advantage. The research design was quantitative and the empirical information was examined in two stages: the first through a confirmatory factorial analysis (CFA) and the second through a system of structural equations based on covariance (SSEBC). Results confirm that: 1) a direct, positive and significant relationship between the capacity of massive personalization and perceived operative performance, 2) reconfiguration capacity affects positively, directly and significantly perceived operative development, and 3) perceived operative development influences perceived competitive advantage in a direct, positive and significant manner.
Object Recognition in High-Resolution Indoor THz SAR Mapped Environment

Synthetic aperture radar (SAR) at the terahertz (THz) spectrum has emerging short-range applications. In comparison to the microwave spectrum, the THz spectrum is limited in propagation range but benefits from high spatial resolution. The THz SAR is of significant interest for several applications which necessitate the mapping of indoor environments to support various endeavors such as rescue missions, map-assisted wireless communications, and household robotics. This paper addresses the augmentation of the high-resolution indoor mapped environment for object recognition, which includes detection, localization, and classification. Indoor object recognition is currently dominated by the usage of optical and infrared (IR) systems. However, it is not widely explored by radar technologies due to the limited spatial resolution at the most commonly used microwave frequencies. However, the THz spectrum provides a new paradigm of possible adaptation of object recognition in the radar domain by providing image quality in good compliance to optical/IR systems. In this paper, a multi-object indoor environment is foremost mapped at the THz spectrum ranging from 325 to 500 GHz in order to investigate the imaging in highly scattered environments and accordingly create a foundation for detection, localization, and classification. Furthermore, the extraction and clustering of features of the mapped environment are conducted for object detection and localization. Finally, the classification of detected objects is addressed with a supervised machine learning-based support vector machine (SVM) model.
Tie-Over Bolster Pressure Dressing Improves Outcomes of Skin Substitutes Xenografts on Athymic Mice

The efficacy of skin substitutes is established for the treatment of burn injuries, but its use is not limited to this condition. This technology has the potential to improve the treatment of various conditions by offering highly advanced and personalized treatments. In vivo studies are challenging but essential to move to clinical use in humans. Mice are the most widely used species in preclinical studies, but the main drawback of this model is the limited surface area of the graft in long-term transplantation studies caused by the displacement and the contraction of the graft. We improved the conventional surgical procedures by stabilizing the chamber covering the graft with intramuscular sutures and by adding a tie-over bolster dressing. The current study was therefore performed to compare outcomes of skin grafts between the conventional and optimized skin graft model. Human self-assembled skin substitutes (SASSs) were prepared and grafted to athymic mice either by the conventional method or by the new grafting method. Graft healing and complications were assessed using digital photographs on postoperative days 7, 14, and 21. Similar structure and organization were observed by histological staining. The new grafting method reduced medium and large displacement events by 1.26-fold and medium and large contraction events by 1.8-fold, leading to a 1.6-fold increase in graft surface area compared to skin substitutes grafted with the usual method. This innovation ensures better reproducibility and consistency of skin substitute transplants on mice.
Approche de dépollution vs approche de non-pollution : quel choix technologique dans l’entreprise algérienne ?

La nécessité pour les entreprises, particulièrement industrielles, de recourir aux technologies environnementales ne fait plus débat. Différents dans leur efficacité, leur coût et leur mode d’installation, ces éco-instruments sont susceptibles de contenir ou d’éliminer complètement toute forme de déséconomie externe sur l’environnement. Le présent travail analysera le choix de type de ces technologies fait par un échantillon d’entreprises du secteur industriel. Comme principal résultat, la préférence d’usage chez ces organismes est, très majoritairement, en faveur d’une optique de non-pollution et en défaveur quasi-absolue de celle de la dépollution.
Similar results for two well-known nonlinear diffusion models, the porous medium equation and p-Laplacian equation, are also obtained on singular manifolds. The theory of differential equations on singular manifolds

(i) The well-posedness problem of geometric flows and diffusion equations on non-compact manifolds, or even manifolds with singularities. Along this line of research, I have proved that the Yamabe flow may start with a weak initial regularity condition, and thus can admit an initial metric with unbounded curvature. Similar results for two well-known nonlinear diffusion models, the porous medium equation and p-Laplacian equation, are also obtained on singular manifolds. The theory of differential equations on singular manifolds can also be applied to degenerate equations on domains with higher order degeneracy at the boundary. In Section 2, a survey on these results will be presented.
Infectivity and Morphology of Bovine Coronavirus Inactivated In Vitro by Cationic Photosensitizers

Bovine coronaviruses (BCoVs), which cause gastrointestinal and respiratory diseases in cattle, and are genetically related to the human coronavirus HCoV-OC43, which is responsible for up to 10% of common colds, attract increased attention. We applied the method of photodynamic inactivation with cationic photosensitizers (PSs) to reduce the titers of BCoV and studied the morphological structure of viral particles under various modes of photodynamic exposure. The samples of virus containing liquid with an initial virus titer of 5 Log10 TCID50/mL were incubated with methylene blue (MB) or octakis(cholinyl)zinc phthalocyanine (Zn-PcChol8+) at concentrations of 1–5 μM for 10 min in the dark at room temperature. After incubation, samples were irradiated with LED (emission with maximum at 663 nm for MB or at 686 nm for Zn-PcChol8+) with light doses of 1.5 or 4 J/cm2. Next, the irradiation titrated virus containing liquid was studied using negative staining transmission electron microscopy. MB and Zn-PcChol8+ at concentrations of 1–5 μM, in combination with red light from LED sources in the low doses of 1.5–4.0 J/cm2, led to a decrease in BCoV titers by at least four orders of magnitude from the initial titer 5 Log10 TCID50/mL. Morphological changes in photodamaged BCoVs with increasing PS concentrations were loss of spikes, change in shape, decreased size of virus particles, destruction of the envelope, and complete disintegration of viruses. BCoV has been found to be sensitive to MB, which is the well-known approved drug, even in the absence of light.
Brain Trauma, Glucocorticoids and Neuroinflammation: Dangerous Liaisons for the Hippocampus

Glucocorticoid-dependent mechanisms of inflammation-mediated distant hippocampal damage are discussed with a focus on the consequences of traumatic brain injury. The effects of glucocorticoids on specific neuronal populations in the hippocampus depend on their concentration, duration of exposure and cell type. Previous stress and elevated level of glucocorticoids prior to pro-inflammatory impact, as well as long-term though moderate elevation of glucocorticoids, may inflate pro-inflammatory effects. Glucocorticoid-mediated long-lasting neuronal circuit changes in the hippocampus after brain trauma are involved in late post-traumatic pathology development, such as epilepsy, depression and cognitive impairment. Complex and diverse actions of the hypothalamic–pituitary–adrenal axis on neuroinflammation may be essential for late post-traumatic pathology. These mechanisms are applicable to remote hippocampal damage occurring after other types of focal brain damage (stroke, epilepsy) or central nervous system diseases without obvious focal injury. Thus, the liaisons of excessive glucocorticoids/dysfunctional hypothalamic–pituitary–adrenal axis with neuroinflammation, dangerous to the hippocampus, may be crucial to distant hippocampal damage in many brain diseases. Taking into account that the hippocampus controls both the cognitive functions and the emotional state, further research on potential links between glucocorticoid signaling and inflammatory processes in the brain and respective mechanisms is vital.
SPONGE FOSSIL OF BRAZIL: REVIEW AND PERSPECTIVES

The Brazilian fossil record holds crucial information regarding the evolutionary history of many invertebrate groups (e.g., cnidarian, bryozoan and brachiopods). Most of them are well-distributed through the formations of intracratonic basins (Amazonas, Paraná, Sergipe-Alagoas and others), which have been studied since the first expeditions in the second half of the 19th century. Among the invertebrate groups, the phylum Porifera, recognized as one of the earliest-branching of metazoan kingdom, is rarely recovered and studied. Beyond the taphonomic biases, one of the reasons for the scant occurrence may be related to lack of interest and inability to recognize the organisms. Thus, aiming to ratify the poriferan presence in time and space on the Brazilian rocks, here we present a review. Despite previously reported, complete sponges are restricted to Carboniferous–Permian interval. Keywords: Porifera, South America, Brazilian basins, Phanerozoic.
