Introduction: The knee joint has a unique anatomical structure in the human body. The localization between the two longest bones in the human body – femur, and tibia – makes it prone to injuries, trauma, and other pathologies. Clinical examination of the joint is still the primary method in evaluating the condition of the patient's knee. The study aims to determine the diagnostic accuracy of clinical examination and magnetic resonance (MR) in assessing chondral lesions of knee joint using arthroscopy as a reference standard.Patients and methods: The examination was conducted on 94 patients (58 males and 36 females) with knee injuries. Clinical examination indicated a primary chondral lesion of knee cartilage in eight patients (five men and three women), with an average age of 45.75. Besides the clinical examination, the diagnostics were performed using MR imaging by Siemens of 0.5 Tesla, and arthroscopy was performed using Storz arthroscope.Results: Our research has generated the following values of clinical and MR results for chondral lesions: Sensitivity (Se) = 12.5%, Specificity (Sp): could not be calculated, Positive Predictive Value (PPV) = 100%, Negative Predictive Value (NPV) = 0% and Accuracy (ACC) = 12.5%. The accuracy of clinical and intraoperative results for chondral lesion was: Se =100%, Sp: could not be calculated, PPV = 100%, NPV: could not be calculated, and ACC = 100%. MR imaging and arthroscopy findings of chondral lesion showed: Se = 100%, Sp = 0%, PPV = 12.5%, NPV: could not be calculated and ACC = 12.5%. In comparing the clinical sign and MRand intraoperative result, Positive Predictive Value for patients with chondral lesion was maximal (100%), while comparing MR with the intraoperative result, Positive Predictive Value was 12.5%. In comparison between clinical sign and intraoperative results, the accuracy for patients with chondral lesion was 100%, while comparing the clinical sign with MR result and MR with the intraoperative result, the accuracy was 12.5%.Conclusion: Our examinations have shown that MR examination is not currently as valid for diagnosing injury of chondral cartilage of knee as the medical community or patients have anticipated it.

Published: November 2021

El presente articulo tiene como finalidad llevar a cabo el desarrollo de una propues­ta de análisis crítico de la evolución social y la educación desde una perspectiva de complejidad. Para esto, se inicia con la conceptualización del conocimiento como valor intrínseco de los individuos y las organizaciones, por lo que su desarrollo va gestando la construcción y comprensión de lo que se conoce como “Sociedad del Conocimiento”. Se hace una aproximación teórica sobre los procesos evolutivos que afectan a la sociedad y como estos dan paso al uso de la tecnología y la innovación en este nuevo orden social que finalmente impacta en la educación. Así mismo, se lleva a cabo el desarrollo de un caso de estudio utilizando agentes para evaluar el proceso de resolución de problemas en la Sociedad del Conocimiento 5.0 en una institución de educación superior, esto ejemplifica la necesidad de abordar el estudio con un enfoque de complejidad, elimina­ción de entropía y sostenibilidad. Cabe señala que en este caso, los agentes (profesor y alumno) utilizan principios BDI y se apegan a la biblioteca de Sakellariou (2008). Fi­nalmente se observa que, bajo los parámetros ingresados de manera empírica, aproxi­madamente un 15 por ciento llega a la generación de conocimiento, se debe considerar que este resultado puede variar si las instituciones definen políticas y acciones a tomar con el fin de incrementar la motivación y disposición de los estudiantes hacia el proceso de creación de conocimiento.

COVID-19 is a relatively new disease whose complete pathogenesis and complications have not been elucidated. Apart from the morbidity and mortality caused by the virus itself, it is noted that patients affected with this virus have a higher susceptibility to bacterial and fungal co-infections. Mucormycosis is a rare and life-threatening fungal infection generally associated with uncontrolled diabetes mellitus and immunosuppression. It tends to rapid disease progression and poor prognosis if not diagnosed and managed promptly. There has been a sudden increase in the number of mucormycosis cases in patients with moderate to severe COVID-19 infection in the past few months. Herein, we present a series of 10 mucormycosis cases diagnosed over one week.

Published: November 2021

With the increase in Internet and local area network usage, malicious attacks and intrusions into computer systems are growing. The design and implementation of intrusion detection systems became extremely important to help maintain good network security. Support vector machines (SVM), a classic pattern recognition tool, has been widely used in intrusion detection. They make it possible to process very large data with great efficiency and are easy to use, and exhibit good prediction behavior. This paper presents a new SVM model enriched with a Gaussian kernel function based on the features of the training data for intrusion detection. The new model is tested with the CICIDS2017 dataset. The test proves better results in terms of detection efficiency and false alarm rate, which can give better coverage and make the detection more effective.

Corporate Social Responsibility and Corporate Financial Performance: An Empirical Literature Review
Authors: Boukattaya Sonia , Achour Zyed , Hlioui Zeineb
Published: November 2021

This study aims to present a literature review of recent studies on the relationship between environmental, social and governance (ESG) performance, corporate social responsibility (CSR) and corporate financial performance (CFP) and to provide a path for future researches. Using content analysis method, a total of 88 papers published in renowned journals, over the period 2015-2021, were selected in the review. Several findings have been made: first, the majority of researches have focused on the CSR’s “social impact” hypothesis on CFP; the reverse relationship seems to have been overlooked. Second, the contested results are likely to be attributable both to differences in research contexts and CSR’ laws but also to biases relating to the operationalization of CSR concept and CFP proxies retained. Finally, several arguments are advanced arguing for an indirect link between CSR and CFP. Future research should, therefore, pay attention to the different contingent variables that are likely to affect the studied relationship.

Published: November 2021

Food serves as one of the requirements for the survival of every living being. It exists in various forms and one of this is Groundnut. Groundnut (Arachis hypogea), apart from being considered for food, creates jobs and sources of income for the teeming populace and contributes to GDP of the countries where grown; its contributions to the national growth increase when its production is mechanized. However, in spite of the use of mechanized method of farming, the contributions are still low in developing countries, compared to the developed countries. Some of the factors responsible for this center on the fact that the available machineries are for turkey projects, which are expensive and as such they are viewed irrelevant among the small scale stakeholders in the developing nations, based on the quantity of their produce. In order to find solution to some of these challenges, the present study utilizes the characteristics of both nuts and shells of groundnuts to develop and evaluate the performance of a 20 kg/h groundnut shelling machine. The machine comprises five basic units, namely: the hopper, neck, shelling unit, power transmission unit and frame. The developed machine with a theoretically loading capacity of 2.5 kg/batch, required average of 58.02 minutes to shell the rated capacity to attain shelling efficiency of 80.39 % with loss of 3.125 % due to crushing. Findings show that the minimum productivity of the machine is 20.666 kg/hr, which improves as the moisture content of the feedstock reduces.

Authors: Daramola O O.
Published: November 2021

Epoxy matrix composites reinforced with clay particles were developed by hand lay-up open mould casting technique. The clay used in this study was pulverized and processed into ultrafine particles through the sedimentation process. The composites were developed by blending the epoxy matrix and hardener with various weight fractions of the ultrafine clay particles (2, 4, 6, 8 and 10 wt%) in open test moulds. In order to accomplish a homogeneous blend of the constituents; manual mixing of the blend was carried out for 3 min. The test specimens were left to cure for 24 hours in the moulds and for additional 27 days at room temperature of 27 Â± 2 Â°C and were thereafter detached from the moulds. The developed composites test specimens were subjected to mechanical tests (flexural, tensile and impact) in accordance with ASTM standards and performed at room temperature. Structural characteristics of the clay particles were determined with the aid of an X-ray diffractometer (XRD). The morphologies of the composites were determined using a scanning electron microscope (SEM). There was a progressive enhancement in the mechanical properties of epoxy composites containing 2-6 wt.% ultrafine clay particles while a drastic decrease in the mechanical properties was noticed in the epoxy/clay composites reinforced with 8-10 wt.% ultrafine clay particles. The SEM images revealed homogeneous particles distributions within the epoxy matrix at lower ultrafine clay particles weight fractions (2 wt. % and 6 wt.%).

Published: November 2021

The climatic chamber is a calibration medium for the thermohygrometer. This simple climatic chamber was built using the Arduino uno, DHT22 sensor, heater, and peltier. The climatic chamber was designed and manufactured well and cheaply. Climatic chamber testing of the design results is carried out to determine the success rate of the tool. Tests are carried out using the Madgetech data logger tool through monitoring or monitoring of temperature within a certain period of time. The results of temperature monitoring at two observed values, namely temperatures of 250C to 300C and temperatures of 300C to 350C, showed good results with the corresponding rhythm of temperature increase and temperature decrease. It's just that the decrease in temperature still takes longer than the increase in temperature. This shows that the heater can be said to be working optimally and the peltier is not fully working. So it is necessary to do further studies related to the peltier for the climatic chamber both in terms of number and characteristics.

Information technology is a technology used to process data, including processing, obtaining, compiling, storing, manipulating data in various ways to produce relevant, accurate and timely information, which is used for personal, business and government purposes and is strategic information for decision making, in recording fixed assets for example, must be managed properly because the need for the data is frequent intensity, the number of items is not small so it is impossible to memorize, the calculation of depreciation of fixed assets of a company needs to be done at the end of every year because it will affect the book value and depreciation expense on the balance sheet and depreciation expense on fixed assets on the income statement. This depreciation calculation can also be used as a reference in the allocation to purchase new assets if the existing fixed assets can no longer be used.

Obstacles in preparing depreciation reports if not resolved immediately will have a bad impact on schools, for example being late in submitting annual tax reports due to the long preparation of depreciation reports will result in schools being fined for being late in reporting the annual corporate tax return. With the accounting information system for depreciation of fixed assets, it is expected that it will facilitate officers in managing fixed asset data and depreciation reports. The new system that will be designed is web-based, so that it can be accessed at any time by interested parties and makes coordination time more effective.

Data security is very important today, because the amount of big data is increasing day by day, forcing every sector to review its security system. The security of SIM and STNK documents is always associated with the authorities. This authority can be public or private. In this country, in the transportation sector, the security of driver's license and vehicle registration documents are given to two private company authorities. Among them are Presprint PI for SIM and High Tech Telesoft for STNK card. Its purpose is to prove the authenticity, availability, and confidentiality of the SIM or STNK holder. However, until now, the security of these documents is still facing obstacles, such as the presence of several individuals who have fake driver's licenses or fake STNKs. Sometimes with the involvement of a particular system manager, the time it takes for the applicant to get a driver's license or STNK card, data management must be secured by one authority. Faced with this situation, to ensure that only qualified people who have the appropriate driving training certificate and have the original driver's license can be allowed to drive the vehicle. System security is optimized through the use of blockchain technology, in data management transparently and without central authority.

Abstract. Data assimilation has led to advancements in
biogeochemical modelling and scientific understanding of the ocean. The
recent operational availability of data from BGC-Argo (biogeochemical Argo) floats, which provide
valuable insights into key vertical biogeochemical processes, stands to
further improve biogeochemical modelling through assimilation schemes that
include float observations in addition to traditionally assimilated
satellite data. In the present work, we demonstrate the feasibility of joint
multi-platform assimilation in realistic biogeochemical applications by
presenting the results of 1-year simulations of Mediterranean Sea
biogeochemistry. Different combinations of satellite chlorophyll data and
BGC-Argo nitrate and chlorophyll data have been tested, and validation with
respect to available independent non-assimilated and assimilated (before the
assimilation) observations showed that assimilation of both satellite and
float observations outperformed the assimilation of platforms considered
individually. Moreover, the assimilation of BGC-Argo data impacted the
vertical structure of nutrients and phytoplankton in terms of deep
chlorophyll maximum depth, intensity, and nutricline depth. The outcomes of
the model simulation assimilating both satellite data and BGC-Argo data
provide a consistent picture of the basin-wide differences in vertical
features associated with summer stratified conditions, describing a
relatively high variability between the western and eastern Mediterranean,
with thinner and shallower but intense deep chlorophyll maxima associated
with steeper and narrower nutriclines in the western Mediterranean.
A missing link in the carbon cycle: phytoplankton light absorption

Abstract. Marine biota and biogeophysical mechanisms, such as phytoplankton light absorption, have attracted increasing attention in recent climate studies. Under global warming, the impact of phytoplankton on the climate system is expected to change. Previous studies analyzed the impact of phytoplankton light absorption under prescribed future atmospheric CO2 concentrations. However, the role of this biogeophysical mechanism under freely-evolving atmospheric CO2 concentration and future CO2 emissions remain unknown. To shed light on this research gap, we perform simulations with the EcoGEnIE Earth system model and prescribe CO2 emissions following the four Representative Concentration Pathways (RCP) scenarios. Under all the RCP scenario, our results indicate that phytopankton light absorption increases the surface chlorophyll biomass, the sea surface temperature, the atmospheric CO2 concentrations and the atmospheric temperature. Under the RCP2.6, RCP4.5 and RCP6.0 scenarios, the magnitude of changes due to phytoplankton light absorption are similar. However, under the RCP8.5 scenario, the changes in the climate system are less pronounced due to the temperature limitation of phytoplankton growth, highlighting the reduced effect of phytoplankton light absorption under strong warming. Additionally, this work evidences the major role of phytoplankton light absorption on the climate system, suggesting a highly uncertain feedbacks on the carbon cycle with uncertainties that are in the range of those known from the land biota.

Published: November 2021

Abstract. The Italian earthquake waveform data are collected here in a dataset suited for machine learning analysis (ML) applications.
The dataset consists of nearly 1.2 million three-component (3C) waveform traces from about 50 000 earthquakes and more than 130 000 noise 3C waveform traces, for a total of about 43 000 h of data and an average of 21 3C traces provided per event.
The earthquake list is based on the Italian Seismic Bulletin (http://terremoti.ingv.it/bsi, last access: 15 February 2020​​​​​​​) of the Istituto Nazionale di Geofisica e Vulcanologia between January 2005 and January 2020, and it includes events in the magnitude range between 0.0 and 6.5.
The waveform data have been recorded primarily by the Italian National Seismic Network (network code IV) and include both weak- (HH, EH channels) and strong-motion (HN channels) recordings.
All the waveform traces have a length of 120 s, are sampled at 100 Hz,
and are provided both in counts and ground motion physical units after deconvolution of the instrument transfer functions.
The waveform dataset is accompanied by metadata consisting of more than 100 parameters providing comprehensive information on the earthquake source, the recording stations, the trace features, and other derived quantities.
This rich set of metadata allows the users to target the data selection for their own purposes.
Much of these metadata can be used as labels in ML analysis or for other studies.
The dataset, assembled in HDF5 format,
is available at http://doi.org/10.13127/instance (Michelini et al., 2021).

Abstract. Disentangling the influence of bedrock erodibility from the respective roles of climate, topography and tectonic forcing on catchment denudation is often challenging in mountainous landscapes due to the diversity of geomorphic processes in action and of spatial/temporal scales involved. The Dora Baltea catchment (western Italian Alps) appears the ideal setting for such investigation, since its large drainage system, extending from the Mont Blanc Massif to the Po Plain, cuts across different major litho-tectonic units of the western Alps, whereas this region has experienced homogeneous climatic conditions and glacial history throughout the Quaternary. We acquired new 10Be-derived catchment-wide denudation rates from 18 river-sand samples collected both along the main Dora Baltea river and at the outlet of its main tributaries. The inferred denudation rate results vary between 0.2 and 0.9 mm/yr, consistent with values obtained across the European Alps by previous studies. Spatial variability in denudation rates was statistically compared with topographic, environmental and geologic metrics. 10Be-derived denudation records do not correlate with the distribution of modern precipitation and rock geodetic uplift. We find, rather, that catchment topography, in turn conditioned by bedrock erodibility (litho-tectonic origin) and glacial overprint, has the main influence on denudation rates. We calculated the highest denudation rate for the Mont Blanc Massif, whose granitoid rocks and long-term tectonic uplift support steep slopes and high relief and thus favour intense glacial/periglacial processes and recurring rock fall events. Finally, our results, in agreement with modern sediment budgets, demonstrate that the high sediment input from the Mont Blanc catchment dominates the Dora Baltea sediment flux, explaining the constant low 10Be concentrations measured along the Dora Baltea course even downstream the multiple junctions with tributary catchments.
Sensitivity of tropospheric ozone to halogen chemistry in the chemistry-climate model LMDZ-INCA vNMHC

Abstract. The atmospheric chemistry of halogenated species (Cl, Br, I) participates in the global chemical sink of tropospheric ozone and perturbs the oxidizing capacity of the troposphere, notably influencing the atmospheric lifetime of methane. Global chemistry-climate models are commonly used to assess the global budget of ozone, its sensitivity to emissions of its precursors, and to project its long-term evolution. Here, we report on the implementation of tropospheric halogens chemistry in the chemistry-climate model LMDZ-INCA and its effects on the tropospheric ozone budget. Overall, the results show that the model simulates satisfactorily the impact of halogens on the photooxidizing system in the troposphere, in particular in the marine boundary layer. To elucidate the mechanisms and quantify the effects, standard metrics representative of the behavior of the tropospheric chemical system (Ox, HOx, NOx, CH4, and NMVOCs) are computed with and without halogen chemistry. Tropospheric halogens in the LMDZ-INCA model lead to a decrease of 22 % in the ozone burden, 8 % in OH, and 33 % in NOx. Additional sensitivity simulations show that the inclusion of halogens chemistry makes ozone more sensitive to perturbations in CH4, NOx, and NMVOCs. Consistent with other global model studies, the sensitivity of the tropospheric ozone burden to changes from pre-industrial to present-day emissions is found to be ~20 % lower when tropospheric halogens are taken into account.
