Circular Economy at the Firm Level: A New Tool for Assessing Maturity and Circularity
Authors: Sacco Pasqualina , Vinante Christian , Borgianni Yuri , Orzes Guido
Published: May 2021

Although the circular economy (CE) concept is gaining traction and methods to assess companies’ CE-related aspects exist, there is no established CE assessment tool. In many cases, it is not clear how metrics or indicators included in extant CE assessment methods have been selected. To fill this gap, this paper presents a new instrument named Circularity and Maturity Firm-Level Assessment tool (CM-FLAT). The CM-FLAT has been developed starting from a transparent scientific basis, i.e., a recent systematic literature review and comprehensive collection of CE metrics. In addition, it targets the separate assessment of CE maturity, i.e., the presence of documented activities and practices laying the foundations for CE introduction, and circularity, i.e., attained CE-related performances. The development of the CM-FLAT has foreseen its formal evaluation by experts in the field of CE and sustainability, and its testing by a pilot group of companies from South Tyrol, Italy. The multiple verification activities have confirmed its usefulness and usability. Therefore, companies can now benefit from a tool capable of providing a comprehensive framework of factors and organizational areas affecting the introduction of the CE. This will be fostered by a computer-supported tool implementing the CM-FLAT, which represents the authors’ future work.
Investors’ Aspirations toward Social Impact: A Portfolio-Based Analysis
Authors: Boni Leonardo , Toschi Laura , Fini Riccardo
Published: May 2021

In the last ten years, we have witnessed a proliferation of investors claiming blended value strategies, i.e., pursuing both economic and social returns in their investments. Aside from this rush for self-selecting in a blended value finance context, we still do not know to what extent the investors’ claims actually reflect investment decisions. Evidence suggests that, in some cases, such investors tend to maximize the social performance over the financial performance; in some others, the effect is reverted, but literature currently lacks studies aligning the analysis of the investment decisions with the investment portfolios. Yet, it is still unclear whether blended value investment decisions are enacted as a result of investors’ deliberate strategies and what influences this relationship. In this paper we tackle this issue, analyzing the extent to which investors’ finance firms pursuing goals aligned with their strategic aspirations. Specifically, adopting a Fractional Logistic Regression model, we test the effect of investors’ aspirations toward social impact on the extent to which their investees (i.e., the portfolio of firms in which they invest) pursue social returns. Results suggest the existence of a positive and significant investor–portfolio alignment effect (i.e., the higher the investors’ aspirations toward social impact, the higher the number of investees with higher social aspirations). Yet, this effect is influenced by contingencies at both investor and portfolio levels. Investors with strong aspirations toward social impact that: (i) invest in countries with high levels of social inequality, and (ii) are located in countries that support social progress and maximize, in their portfolios, the presence of businesses pursuing social impact. We discuss implications for future researchers, policymakers and practitioners.
Application of Data Validation and Reconciliation to Improve Measurement Results in the Determination Process of Emission Characteristics in Co-Combustion of Sewage Sludge with Coal
Authors: Kozioł Michał , Kozioł Joachim
Published: May 2021

One of the actions popularized worldwide to reduce the consumption of fossil fuels is the combustion of renewable fuels and the co-combustion of both of these fuels. To properly implement combustion and co-combustion processes in power-generation installations, operational characteristics, including emission characteristics are required. To determine these characteristics, tests must be conducted, within the scope of which, for individual operating stages of the installation’s work, the readings collected from a relatively large number of control and measurement instruments should be taken into account. All these instruments have different levels of accuracy, which, among other factors, bring about lower adequacy of the characteristics determined on the basis of these measurements. The objective of this study is to present possible adaptations of data validation and reconciliation methods to increase the adequacy of emission characteristics for the process of co-combustion of fuels. The methodology is discussed based on the example of studies on the co-combustion process of sewage sludge with coal in a grate furnace. The aforementioned characteristics were determined based on measurement tests of gaseous emissions of flue gas components. The tests were carried out for various preset operational conditions of the process, such as the thickness of fuel layer on the grate, the share of sludge in the fuel, the humidity of the sludge, the theoretical ratio of excess air to combustion, and the distribution of air stream during the process. The research object is described and detailed research results concerning two exemplary measurement tests are given, as well as the most important results referring to the whole research. The performed calculations indicate the necessity to take into account often significant corrections, which can amount to about 10% of the measured value.

Published: May 2021

To analyse the prevalence of severe and critical COVID-19 cases and its determinants, a systematic review and meta-analysis were conducted using Review Manager. Four English and two Chinese databases were used to identify and explore the relationships between the severity of COVID-19 and its determinants, with no restrictions on publication date. The odds ratio and 95% CI were combined to assess the influencing level of all factors. Twenty-three articles containing a total of 15,828 cases of COVID-19 were included in this systematic review. The prevalence of severe and critical COVID-19 cases was 17.84% and 4.9%, respectively. A total of 148 factors were identified, which included behavioural, symptom, comorbidity, laboratory, radiographic, exposure, and other factors. Among them, 35 factors could be included in the meta-analysis. Specifically, for example, the male (OR 1.55, 95% CI 1.42–1.69) and elderly (OR 1.06, 95% CI 1.03–1.10) populations tended to experience severe and critical illness. Patients with cough, dyspnea, fatigue, fever, and gastrointestinal symptoms could have severe and critical diseases. Regarding laboratory results, albumin, aspartate aminotransferase, creatinine, D-dimer, fibrinogen, neutrophils, procalcitonin, platelets, and respiratory rate were potential factors that could be used to predict the severity of COVID.

Published: May 2021

In general, the stone pagoda structures with discontinuous surfaces are vulnerable to lateral forces and are severely damaged by earthquakes. After the Gyeongju earthquake in 2016 and the Pohang earthquake in 2017, numerous stone pagoda structures were damaged due to slippage, rotation, and the separation of stacked stone. To evaluate seismic resistance of masonry stone pagoda structures, we analyzed the seismic behavior of stone pagoda structures using the shaking table test. Shaking frequency, permanent displacement, maximum acceleration, rocking, and sliding were assessed. Responses to simulations of the Bingol, Gyeongju, and Pohang earthquakes based on the Korean seismic design standard (KDS 41 17 00) were analyzed for return periods of 1000 and 2400 years. We found that the type of stylobate affected the seismic resistance of the stone pagoda structure. When the stylobates were stiff, seismic energy was transferred from lower to upper regions of the stone pagoda, which mainly resulted in deformation of the upper region. When the stylobates were weak, earthquake energy was absorbed in the lower regions, which was associated with large stylobate deformations. The lower part of the tower body was mainly affected by rocking, because the structural members were slender. The higher part of the stone pagoda was mainly affected by sliding, because the load and contact area decreased with height.

Published: May 2021

In South Korea, in line with the increasing need for a reliable water supply following the continuous increase in water demand, the Smart Water Grid Research Group (SWGRG) was officially launched in 2012. With the vision of providing water welfare at a national level, SWGRG incorporated Information and Communications Technology in its water resource management, and built a living lab for the demonstrative operation of the Smart Water Grid (SWG). The living lab was built in Block 112 of YeongJong Island, Incheon, South Korea (area of 17.4 km2, population of 8000), where Incheon International Airport, a hub for Northeast Asia, is located. In this location, water is supplied through a single submarine pipeline, making the location optimal for responses to water crises and the construction of a water supply system during emergencies. From 2017 to 2019, ultrasonic wave type smart water meters and IEEE 802.15.4 Advanced Metering Infrastructure (AMI) networks were installed at 527 sites of 958 consumer areas in the living lab. Therefore, this study introduces the development of SWG core element technologies (Intelligent water source management and distribution system, Smart water distribution network planning/control/operation strategy establishment, AMI network and device development, Integrated management of bi-directional smart water information), and operation solutions (Smart water statistics information, Real-time demand-supply analysis, Decision support system, Real-time hydraulic pipeline network analysis, Smart DB management, and Water information mobile application) through a field operation and testing in the living lab.
Modeling 3D–1D Junction via Very-Weak Formulation
Authors: Marušić-Paloka Eduard
Published: May 2021

We study the potential flow of an ideal fluid through a domain that consists of a reservoir and a pipe connected to it. The ratio of the pipe’s thickness and its length is considered as a small parameter. Using the rigorous asymptotic analysis with respect to that small parameter, we derive an effective model governing the the junction between a 1D and a 3D fluid domain. The obtained boundary-value problem has a measure boundary condition with Dirac mass concentrated in the junction point and is understood in the very-weak sense.
Recursively Divided Pancake Graphs with a Small Network Cost
Authors: Seo Jung-Hyun , Lee Hyeong-Ok
Published: May 2021

Graphs are often used as models to solve problems in computer science, mathematics, and biology. A pancake sorting problem is modeled using a pancake graph whose classes include burnt pancake graphs, signed permutation graphs, and restricted pancake graphs. The network cost is degree × diameter. Finding a graph with a small network cost is like finding a good sorting algorithm. We propose a novel recursively divided pancake (RDP) graph that has a smaller network cost than other pancake-like graphs. In the pancake graph Pn, the number of nodes is n!, the degree is n − 1, and the network cost is O(n2). In an RDPn, the number of nodes is n!, the degree is 2log2n − 1, and the network cost is O(n(log2n)3). Because O(n(log2n)3) < O(n2), the RDP is superior to other pancake-like graphs. In this paper, we propose an RDPn and analyze its basic topological properties. Second, we show that the RDPn is recursive and symmetric. Third, a sorting algorithm is proposed, and the degree and diameter are derived. Finally, the network cost is compared between the RDP graph and other classes of pancake graphs.

Published: May 2021

Vaccines are considered one of the greatest global health achievements, improving the welfare of society by saving lives and substantially reducing the burden of infectious diseases. However, few vaccines are fully effective, for reasons ranging from intrinsic limitations to more contingent shortcomings related, e.g., to cold chain transport, handling and storage. In this context, subunit vaccines where the essential antigenic traits (but not the entire pathogen) are presented in rationally designed fashion have emerged as an attractive alternative to conventional ones. In particular, this includes the option of fully synthetic peptide vaccines able to mimic well-defined B- and T-cell epitopes from the infectious agent and to induce protection against it. Although, in general, linear peptides have been associated to low immunogenicity and partial protection, there are several strategies to address such issues. In this review, we report the progress towards the development of peptide-based vaccines against foot-and-mouth disease (FMD) a highly transmissible, economically devastating animal disease. Starting from preliminary experiments using single linear B-cell epitopes, recent research has led to more complex and successful second-generation vaccines featuring peptide dendrimers containing multiple copies of B- and T-cell epitopes against FMD virus or classical swine fever virus (CSFV). The usefulness of this strategy to prevent other animal and human diseases is discussed.
Assessing the Protective Dose of a Candidate DIVA Vaccine against Classical Swine Fever
Authors: Jelsma Tinka , Post Jacob , Born Erwin van den , Segers Ruud , Kortekaas Jeroen
Published: May 2021

Classical swine fever is a highly contagious and deadly disease in swine. The disease can be controlled effectively by vaccination with an attenuated virus known as the “Chinese” (C)-strain. A single vaccination with the C-strain provides complete protection against highly virulent isolates within days after vaccination, making it one of the most efficacious veterinary vaccines ever developed. A disadvantage of the C-strain is that vaccinated animals cannot be serologically differentiated from animals that are infected with wild-type Classical swine fever virus. Previously, a C-strain-based vaccine with a stable deletion in the E2 structural glycoprotein was developed, which allows for differentiation between infected and vaccinated animals (DIVA). The resulting vaccine, which we named C-DIVA, is compatible with a commercial E2 ELISA, modified to render it suitable as a DIVA test. In the present work, three groups of eight piglets were vaccinated with escalating doses of the C-DIVA vaccine and challenged two weeks after vaccination. One group of four unvaccinated piglets served as controls. Piglets were monitored for clinical signs until three weeks after challenge and blood samples were collected to monitor viremia, leukocyte and thrombocyte levels, and antibody responses. The presence of challenge virus RNA in oropharyngeal swabs was investigated to first gain insight into the potential of C-DIVA to prevent shedding. The results demonstrate that a single vaccination with 70 infectious virus particles of C-DIVA protects pigs from the highly virulent Brescia strain.

Published: May 2021

The use of natural substances such as essentials oils against bee pathogens is of great interest as an alternative to traditional methods based on synthetic compounds like antibiotics and fungicides, in order to minimize the risk of having toxic residues in hive products and to prevent the development of resistance phenomena. This study evaluated the inhibitory, fungicidal and sporicidal activity of ten essential oils extracted from aromatic plants against Ascosphaera apis, the etiological agent of chalkbrood, an invasive honey bee mycosis. The most effective essential oils were Thymus herba-barona, Thymus capitatus and Cinnamomum zeylanicum, which showed values of minimum fungicidal concentration and minimum sporicidal concentration ranging from 200 to 400 ppm. Carvacrol was the main component of Thymus capitatus and Thymus herba-barona oils, whereas cinnamic aldehyde prevailed in Cinnamomum zeylanicum oil. Further in-apiary studies will allow the evaluation of side effects on bees and residues in hive products.
Effect of Salinity on UVA-Vis Light Driven Photo-Fenton Process at Acidic and Circumneutral pH
Authors: Vallés Iván , Santos-Juanes Lucas , Amat Ana M. , Moreno-Andrés Javier , Arques Antonio
Published: May 2021

In the present work, the treatment of a mixture of six emerging pollutants (acetamiprid, acetaminophen, caffeine, amoxicillin, clofibric acid and carbamazepine) by means of photo-Fenton process has been studied, using simulated sunlight as an irradiation source. Removal of these pollutants has been investigated in three different aqueous matrices distinguished by the amount of chlorides (distilled water, 1 g L−1 of NaCl and 30 g L−1 of NaCl) at a pH of 2.8 and 5.0. Interestingly, the presence of 1 g L−1 was able to slightly accelerate the pollutants removal at pH = 5, although the reverse was true at pH = 2.8. This is attributed to the pH-dependent interference of chlorides on photo-Fenton process, that is more acute in an acidic medium. As a matter of fact, the fastest reaction was obtained at pH = 3.5, in agreement with literature results. Monitoring of hydrogen peroxide consumption and iron in solution indicates that interference with chlorides is due to changes in the interaction between iron and the peroxide, rather than a scavenging effect of chloride for hydroxyl radicals. Experiments were also carried out with real seawater and showed higher inhibition than in the NaCl experiments, probably due to the effect of different dissolved salts present in natural water.
An Improved Inexact Two-Stage Stochastic with Downside Risk-Control Programming Model for Water Resource Allocation under the Dual Constraints of Water Pollution and Water Scarcity in Northern China
Authors: Meng Chong , Li Wei , Cheng Runhe , Zhou Siyang
Published: May 2021

Water resource allocation aimed at sustainable watershed development suffers from prominent challenges such as water pollution and scarcity, especially in water-deprived regions. Based on analysis of water quality, use, and sectoral demands during the planning period in the Fenhe River Basin, an improved inexact two-stage stochastic programming model with downside risk control was built for optimal resource allocations for the four primary sectors (industry, domestic use, agriculture, and the environment) in the basin. The principal constraints are river water quality and available water resources under the three hydrological scenarios (low, medium, and high). The results show that industrial, domestic, and agricultural water use in the middle and lower reaches were significantly reduced by requiring improved water quality; agriculture suffered the greatest water shortage and risk. As the level of risk control improved, the comprehensive watershed benefits and agricultural risks were gradually reduced. Improving water reuse significantly reduces the risk and increases the benefits. The model can effectively manage rational water allocations under the dual constraints of water quality and quantity, meanwhile alleviating water competition caused by different water benefits to provide support for coordinating the improvement of water quality and socio-economic development in the basin.
Structure and Dynamics of Interfacial Water on Muscovite Surface under Different Temperature Conditions (298 K to 673 K): Molecular Dynamics Investigation
Authors: Shiga Masashige , Aichi Masaatsu , Sorai Masao , Morishita Tetsuya
Published: May 2021

We performed molecular dynamics (MD) simulations to study structure, stability, and dynamics of the water adsorption layer on muscovite mica at several temperatures (from 298 K to 673 K) and pressures (0.1 MPa, 10 MPa, and 50 MPa). We studied the structure of the adsorption layers with three characteristic peaks of density and orientation of H2O molecules in one-dimensional and two-dimensional profiles. The results show that the water adsorption layers become less structured and more mobile as the temperature increases. We also found the first and the second layers are less diffusive than the third one, and the difference of diffusivity gets unclear as the temperature increases. Finally, we discuss implications to hydration forces and wettability, which are significant interfacial properties of the multiphase fluids system such as water/gas/mineral systems, from the viewpoint of water adsorption film with nanometer thickness.

This study determined the comparative analysis of project and demonstration teaching methods in improving students’ academic achievement in basic electricity in technical colleges. The study adopted quasi-experimental design; specifically, pre-test, post-test for non-randomized and unequal groups were used. One research question guided the study and one hypothesis was tested at 0.05 level of significance. Four technical colleges in Ebonyi State, each technical college offering basic electricity, were used. A total of 141 Technical College year II (TC II) students formed the population of the study. The instruments used in the study were Basic Electricity Achievement Test (BEAT), Project Method Instructional Manual (PMIM) and Demonstration Method Instructional Manual (DMIM), which were validated by three experts. The instrument (BEAT) was administered twice to twenty (20) TC11 students in Enugu State and Pearson’s Product Moment Correlation was used to obtain a reliability index of 0.89. Data collected for the study were analyzed using mean and standard deviation for research question, while the hypothesis was tested using Analysis of Covariance (ANCOVA). The study found more improvement in students’ academic achievement when taught basic electricity using project teaching method than when taught using demonstration teaching method. The study therefore showed that project teaching method was more effective than demonstration teaching method in enhancing students’ academic achievement in basic electricity. The researchers therefore recommended among other things that teachers should embrace project teaching method more than demonstration teaching method to enhance students’ academic achievement in basic electricity.

Published: May 2021

Many control approaches are used today to prevent the contamination of soils with heavy metals and to remove pollution. One of these approaches is phytoremediation for the on-site treatment of pollutants. In phytoremediation, hyperaccumulator plants are used, which absorb heavy metals, accumulate at high levels in their tissues, and neutralize them after various processes. It was aimed to determine the effects of heavy metals on plant growth and the heavy metal accumulation capacity of plants in this study. Using the phytoremediation method, the growth process of the canola plant and its lead removal capacity from the soil were investigated. The study was carried out in 3 replicates by watering the plants only with tap water and tap water containing different concentrations of lead in greenhouse conditions. The prepared soil mixture was placed in pots as 2000 g pot-1. The sown seeds were germinated using tap water in the plant growing room and the water requirement of the plants was met with tap water containing a certain concentration of lead during the next growing period. Plants were harvested at the end of the 3 month growth period. The plants irrigated with the lead solution were compared only with the plants irrigated with tap water, and the elongation amounts of root and stem lengths were determined. Plant samples with dry weights determined were burned with certain chemicals using the microwave method, and then the amount of lead in the plants was measured with the ICP-MS device.

La “excritura” con el cuerpo: el erotismo como transgresión
Authors: Concha López Teresa
Published: May 2021

La tradición metafísica se caracteriza por otorgarle una primacía a “lo racional”  por sobre “lo sensible”. El primer elemento es universal y necesario, mientras que lo sensible es lo contingente y mutable, por tanto perecedero. En este pensamiento erigido a partir de binomios conceptuales tales como naturaleza-cultura, pathos y logos, sensibilidad-entendimiento, cuerpo-alma, mujer-hombre, reina la actividad por sobre la pasividad. A partir de tales escisiones proponemos relacionar dos de esas oposiciones: 1.cuerpo- alma y 2.mujer –hombre con la acción de escribir ¿Está la escritura determinada por el sexo? Si se escribe “con el cuerpo”, ¿es siempre desde un cuerpo sexuado? Por otra parte, nos interesa rescatar algunas ideas del pensamiento de Bataille y de Jean-Luc Nancy a fin de preguntar acerca de lo que Nelly Richard llama la “feminización de la escritura” que estaría dada por cierta fuerza de subjetivación que va más allá de la diferencia sexual. Por último, proponemos que el cuerpo y la escritura formarían una unidad inescindible, si se piensan en los términos de Bataille (Erotismo) o Jean-Luc Nancy (“excritura”).

No hay perros guardianes, solo un mito sobre el poder
Authors: Rey Domínguez Valentina
Published: May 2021

Durante décadas el mito periodístico ha servido para explicar la profesión, dotarla de sentido, identidad y legitimidad; otorgándole así un rol dentro de la sociedad. Bajo el ideal de “cuarto poder del Estado”, “perro guardián de la democracia”, el mito ha instalado valores éticos que han normado las prácticas y actitudes profesionales. Sin embargo, la realidad da cuenta de una distancia entre aquel ideal y el ejercicio periodístico; una dicotomía entre el mito y la práctica. El presente ensayo propone que aquel problema radica en el mito, en una construcción enunciativa que teóricamente presenta una imposibilidad práctica, pero que establece una relación de poder que limita y norma las actitudes periodísticas, instalando principios éticos como verdades absolutas y doctrinarias. Por lo tanto, nos proponemos cuestionar los mecanismos de producción de verdad presentes en el mito; aquellos que fijan un orden de relaciones, en cómo el periodista debe entender y ejecutar su profesión.

SPONTANEOUS PERFORATION OF MECKEL'S DIVERTICULUM: A CASE REPORT AND REVIEW OF LITERATURE
Authors: Santhi B. , A Subhashini . , V Preethi.
Published: May 2021

Meckel's diverticulum is the commonest congenital abnormality of the gastrointestinal tract. Hemorrhage
obstruction and inammation are the three main categories of complications resulting from Meckel's
diverticulum. Spontaneously perforation of Meckel's diverticulum is very rare and mimics acute appendicitis. We report a case
of 65 year-old female, who presented since 2 days worsening abdominal pain predominantly in the right iliac fossa associated
with high grade fever and nausea. On physical examination her abdomen revealed diffuse tenderness, more over the right iliac
fossa and the hypogastric region with guarding in the right iliac fossa. A provisional diagnosis of appendicular perforation was
made. Our patient had an emergency laparotomy, where a perforated Meckel's diverticulum and advanced peritonitis were
discovered. A resection of ileum with meckels diverticulum with end to end anastomosis of ileal loops were performed.
Heterotopic mucosa of diverticulitis was conrmed on histopathology. The patient made an uneventful recovery postoperatively
. This case report is an interesting and unusual case of Meckel's diverticulum complications and highlights the importance of
considering Meckel's diverticulum as a differential diagnosis in every patient presenting with acute abdomen.

Published: May 2021

Background: Preeclampsia is a multisystem disorder which affects about 2% of pregnancies and
represents a major threat to mother and foetus when it emerges. In some women this condition sets in a
subtle way and gradually such women develop severe degree of preeclampsia leading to dreadful complications. Uterine
artery doppler velocimetry is a non-invasive method to examine the uteroplacental circulation that provides indirect evidence of
blood ow and is proposed a predictive test for preeclampsia. This prospective observational study was performed to assess
the usefulness of uterine artery Doppler in predicting preeclampsia.
Methods: 50 high risk and 50 low risk singleton pregnancies between 16-28 weeks of gestational age with uterine artery doppler
study were followed up till delivery or development of preeclampsia to determine maternal and fetal outcome.
Results: Sensitivity and specicity of abnormal uterine artery doppler study for prediction of preeclampsia were 90 % and 70 %
in high-risk and 42 % and 90 % in low-risk group, respectively. Positive predictive value and negative predictive value was 92 %
and 63 % in high risk group and 42 % and 90 % in low risk group respectively.
Conclusions: Mid trimester doppler velocimetry of uterine artery can be used as a reliable screening test for prediction of
preeclampsia in both high-risk and low-risk women.
IMPACT OF PREGNANCY INDUCED HYPERTENSION ON ANTHROPOMETRIC MEASUREMENTS OF A NEWBORN AT BIRTH
Authors: Kaur Simrat , Kumar Naresh
Published: May 2021

Study design: Observational, cross sectional study.
Background: Pregnancy induced hypertension remain amongst the most signicant and intriguing
unsolved problem in obstetrics. It leads to preterm birth, intrauterine growth restriction (IUGR), perinatal death, antepartum
hemorrhage and maternal death. This study was conducted to determine the impact of pregnancy induced hypertension on
anthropometric measurements of a newborn at birth.
Method: The present study was conducted over a period of 18 months on newborns of mothers with Pregnancy Induced
Hypertension admitted in Department of Obstetrics & Gynaecology and received in department of Pediatrics in Sri Guru Ram
Das University of Health Science, Sri Amritsar. It was an observational study in which newborns of mothers with pregnancy
induced hypertension were taken up as subjects to determine the weight, height, head circumference and length at birth. A total
of 80 pregnant women with PIH were enrolled in this study following the inclusion and exclusion criteria.
Results: In 80 pregnant females with PIH, most of the cases were of preeclampsia (51%), followed by gestational hypertension
(43%). 54% of total PIH mothers delivered preterm babies. Mean weight, head circumference and length of babies were
signicantly affected by the severity of PIH. 56% newborns had normal birthweight.
Conclusion: It was observed that length followed by head circumference and weight were signicantly affected by the severity
of PIH in mothers.

En muchas industrias se emplean fluidos en los procesos de producción. Estos fluidos, sean líquidos, gases o mezclas de ambos, se almacenan en depósitos y se transportan por conductos en las instalaciones industriales. El volumen que cada kilogramo de fluido ocupa en estas instalaciones puede variar si también lo hacen su presión y temperatura. Encontrar esta interdependencia entre presión, volumen y temperatura resulta crucial para dimensionar depósitos y conductos. Conocer la relación matemática que expresa la interdependencia física de estas tres propiedades es esencial en ingeniería. En este libro veremos de modo experimental la interdependencia que presentan las propiedades presión, volumen y temperatura en fluidos. Lo haremos a través un caso práctico. En este libro mostraremos: 1) la dependencia mutua de las variables de estado presión-volumen-temperatura (PVT) para el fluido contenido en un volumen variable al modificar la presión y la temperatura. 2 ) la distinción de las propiedades de un fluido en las diferentes zonas de operación. 3 ) la obtención de la curva de vaporización presión-temperatura (P-T) y el diagrama presión-volumen (P-V) de un fluido.
An Efficient Dimension Reduction based Fusion of CNN and SVM Model for Detection of Abnormal Incident in Video Surveillance

Published: May 2021

Performing dimensionality reduction in the camera captured images without any loss is remaining as a big challenge in image processing domain. Generally, camera surveillance system is consuming more volume to store video files in the memory. The normally used video stream will not be sufficient for all the sectors. The abnormal conditions should be analyzed carefully for identifying any crime or mistakes in any type of industries, companies, shops, etc. In order to make it comfortable to analyze the video surveillance within a short time period, the storage of abnormal conditions of the video pictures plays a very significant role. Searching unusual events in a day can be incorporated into the existing model, which will be considered as a supreme benefit of the proposed model. The massive video stream is compressed in preprocessing the proposed learning method is the key of our proposed algorithm. The proposed efficient deep learning framework is based on intelligent anomaly detection in video surveillance in a continuous manner and it is used to reduce the time complexity. The dimensionality reduction of the video captured images has been done by preprocessing the learning process. The proposed pre-trained model is used to reduce the dimension of the extracted image features in a sequence of video frames that remain as the valuable and anomalous events in the frame. The selection of special features from each frame of the video and background subtraction process can reduce the dimension in the framework. The proposed method is a combination of CNN and SVM architecture for the detection of abnormal conditions at video surveillance with the help of an image classification procedure. This research article compares various methods such as background subtraction (BS), temporal feature extraction (TFE), and single classifier classification methods.
