Probabilistic Mesoscale Analysis of Concrete Beams Subjected to Flexure
Authors: Al-Jelawy Haider M. , Al-Rumaithi Ayad , Fadhil Aqeel T. , Al-Sherrawi Mohannad H.
Published: August 2021

In this paper, the probabilistic behavior of plain concrete beams subjected to flexure is studied using a continuous mesoscale model. The model is two-dimensional where aggregate and mortar are treated as separate constituents having their own characteristic properties. The aggregate is represented as ellipses and generated under prescribed grading curves. Ellipses are randomly placed so it requires probabilistic analysis for model using the Monte Carlo simulation with 20 realizations to represent geometry uncertainty. The nonlinear behavior is simulated with an isotropic damage model for the mortar, while the aggregate is assumed to be elastic. The isotropic damage model softening behavior is defined in terms of fracture mechanics parameters. This damage model is compared with the fixed crack model in macroscale study before using it in the mesoscale model. Then, it is used in the mesoscale model to simulate flexure test and compared to experimental data and shows a good agreement. The probabilistic behavior of the model response is presented through the standard deviation, moment parameters and cumulative probability density functions in different loading stages. It shows variation of the probabilistic characteristics between pre-peak and post-peak behaviour of load-CMOD curves.
Wavelet-Based Numerical Solution for MHD Boundary-Layer Flow Due to Stretching Sheet
Authors: Karkera Harinakshi , Katagi Nagaraj N.
Published: August 2021

In this paper, a two-dimensional steady flow of a viscous fluid due to a stretching sheet in the presence of a magnetic field is considered. We proposed two new numerical schemes based on the Haar wavelet coupled with a collocation approach and quasi-linearization process for solving the Falkner-Skan equation representing the governing problem. The important derived quantities representing the fluid velocity and wall shear stress for various values of flow parameters M and β are calculated. The proposed methods enable us to obtain the solutions even for negative β, nonlinear stretching parameter, and smaller values of the magnetic parameter (M < 1) which was missing in the earlier findings. Numerical and graphical results obtained show an excellent agreement with the available findings and demonstrate the efficiency and accuracy of the developed schemes. Another significant advantage of the present method is that it does not depends on small parameters and initial presumptions unlike in traditional semi-analytical and numerical methods.

Authors: Manjula L. , Muthucumaraswamy R.
Published: August 2021

MHD and radiated heat flow on a rotating system of an electrically conducting fluid in the presence of Hall current under the influence of variable temperature is studied analytically. An exact solution of a non-dimensional form of coupled partial differential equations is obtained by the technique of Laplace transform. The effect of temperature, velocity and concentration is analyzed for various parameters like the Hall parameter (m), thermal radiation (R), rotation parameter (Ω), Hartmann number (M) and results are discussed in detail with the help of graphs. A mixed analysis of a rotating fluid with Hall current and thermal radiation plays a very essential role in the research area such as plasma physics, MHD generator, fluid drift sensor, cosmological and geophysical level, etc.
Static Bending of Isotropic Circular Cylindrical Shells Based on the Higher Order Shear Deformation Theory of Reddy and Liu
Authors: Nwoji C.U. , Ani D.G. , Oguaghamba O.A. , Ibeabuchi V.T.
Published: August 2021

In this paper, a displacement based shear deformation theory formulated on the cubic in-plane displacement field equation of Reddy and Liu is presented for the static bending analysis of isotropic circular cylindrical shells. The adopted displacement field accounts for a quadratic (parabolic) distribution of the transverse shear through the shell thickness as well as satisfies the need for a stress free upper and lower boundary surfaces of the shell. The equations of static equilibrium are obtained on application of the principle of virtual work. Numerical results of the bending analysis for the displacements and stresses are presented for the simply supported shell. A comparison made to those of the Kirchhoff-Love theory for varying shell length to mean – radius of curvature ratios, shows good agreement for thin shells irrespective of the shell length to radius of curvature ratio (l / a). The transverse sharing effect is found to be noticeable in the deformation of thick shells, however, this effect diminishes with a continuous increase in l / a ratios.
Numerical Study on Dimensions and Orientation Effect of Semi-Elliptical Cracks in PE100 Pipelines
Authors: Zitouni T.A. , Labed Z.
Published: August 2021

The through-thickness crack or surface crack in PE100 pipes subjected to internal pressure represents a serious risk to the structural integrity of HDPE pipes, which has attracted wide attention in modern industry. Although experimental research offers reliable predictions of surface crack influence on pipes, the relatively high cost hinders its application. The numerical simulation, as a cost-effective alternative, has been widely applied to assess stress displacement and strain to the entire pipe structure. This is the initial approach adopted in recent decades. This article provides simulations tests of an uncracked pipe and cracked PE100 pipe under different internal pressure values, with varying each time the dimensions of the crack with 1 mm rate for minor and major radius and 0.5mm rates for the largest contour radius, using ANSYS MECHANICAL STRUCTURAL STATIC for simulation.

Published: August 2021

The study was planned to evaluate the use of laparoscopy for the diagnosis and retrieval of abdominal cysts in sheep and goats. The abdominal cysts were located in 10 of 135 adult, healthy small ruminants by using ultrasonography (USG). Percutaneous Puncture-Aspiration-Injection-Reaspiration (PAIR) technique was used for six animals. Thirty animals, including four diagnosed with abdominal cysts by USG, were subsequently subjected to laparoscopy under diazepam sedation (0.1 mg/kg, IV) and lumbosacral epidural regional anesthesia using 2% lignocaine hydrochloride (1.0 ml/5 kg). The animals were restrained in dorsal recumbency and two-port paramedian laparoscopy was performed. Abdominal cysts were located in seven animals (one cyst/animal). The cysts were grasped carefully, lifted close to the abdominal wall, and evacuated percutaneously under laparoscopic vision. The collapsed cysts were then retrieved. In two animals enlarged ports were sutured, treated with an antibiotic and an analgesic, resulting in uneventful healing. Five cysts were nonparasitic, two were parasitic, one extracted from a sheep, and one from a goat. In conclusion, laparoscopy has higher diagnostic accuracy in detecting unattached abdominal cysts in sheep and goats compared to USG. It is also a reliable, minimally invasive, and safe procedure for cyst retrieval. However, a larger-scale study is necessary for ascertaining long-term complications and the recurrence rate.

Published: August 2021

Introduction. The aim was to evaluate the effect of therapeutic plasma exchange (TPE) and eculizumab on hematological and renal survival in atypical hemolytic uremic syndrome (aHUS), and additionally, to examine the reliability of discontinuation of eculizumab treatment.

Methods. This was an observational and retrospective study of 18 patients diagnosed with aHUS.

Results. The median age of the study population was 30 (22–66) years. Four of 18 patients achieved hematological remission with the TPE alone. However, one patient died after three sessions of TPE. Eculizumab was used in 13 patients and no death was observed. One year after treatment, improved kidney function was observed in 2 of 3 (66%) patients for TPE and 5 of 9 (56%) patients for Eculizumab. We discontinued eculizumab treatment in 9 patients. One of the patients who had a C3 gene mutation experienced disease relapse after Eculizumab discontinuation. None of the patients who had drug associated aHUS developed disease relapse after Eculizumab discontinuation.

Conclusion. Eculizumab treatment is a life-saving therapy in aHUS. Treatment discontinuation may be considered at least six months after hematologic remission in patients who had stable renal function or no expectancy for renal survival. Moreover, drug-associated cases seem to tend not to develop disease relapse in the long term.

Published: August 2021

Background. The management of lactation in preterm mothers is a real challenge for Neonatal Intensive Care Unit (NICU) care, providers. The study aimed to evaluate the enablers and barriers for enteral feeding with mothers` own milk (MOM) in preterm very low birth weight (VLBW) infants in a tertiary care neonatal unit.
Methods. This prospective observational study took place at a tertiary level NICU of a high-risk obstetric unit in a private hospital. All VLBW infants and mothers were incorporated into the study. Data on enablers and barriers were gathered from mother-baby dyads at the time of birth, at the end of the 7th day, and then weekly till the discharge of the baby from the unit.
Results. We studied 87 mother-baby dyads. Mean (SD) maternal age, gestation age and birth weight were 29.3 (4.7) years, 30.8 (2.0) weeks, and 1196 (196) grams respectively. We categorized our data into 2 groups based on outcome estimates done during the entire hospital stay or pre-discharge (48 hours before the discharge). On comparison of perinatal and post-natal factors, the enablers were maternal dwelling from the rural locality, number of milk expression son day 1 after the birth, number of night expressions in the first week postnatally, and MOM volume till day 3, day 7, and 2 weeks postnatally. The enablers of MOM in the pre-discharge group were the number of expressions in the first 3 days, the number of night expressions in week 1, mother`s visit, and the number of maternal visits on day 1 to NICU and MOM volume expressed from day 1 until the second week after birth. The main barriers for MOM (48 hours pre-discharge) were extremely low birth weight (ELBW) and intrauterine growth-restricted infants (IUGR).
Conclusions. ELBW infants and IUGR infants are susceptible to low MOM feeding. The total of milk expressions in the first 3 days, number of night expressions in the first week, maternal visits on day 1 and the average MOM amount in the first 2 weeks are enablers for MOM feeding.

Published: August 2021

Background. We studied microRNAs (miRNAs) -146a, -155, -181 and -223 expressions and proinflammatory cytokine levels in children with Febrile seizure (FS) and compared to febrile controls.
Methods. This prospective multicenter study examined representative populations in eight different cities in Turkey between June 30, 2018 and July 1, 2019. Blood samples were taken from all children at presentation. The real time (RT) polymerase chain reaction (PCR) were used to measure the expressions of microRNAs and tumor necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1β), and interleukin 6 (IL-6) levels were studied by enzyme-linked immuno-sorbent assay.
Results. The study was conducted with 60 children; 30 children with FS and 30 children in the febrile control group. The seizure was classified as simple FS in 73.3 % and half of the children were experiencing their first FS episode. Although the expression levels of miRNAs-146a, -181a and -155 were higher in febrile seizure patients, only miRNAs 146a level was significantly higher in FS patients. Serum TNF-α, IL-1β, IL-6 levels were higher in the FS group than the controls. The results of statistical analysis showed that there were correlations within miRNA expressions in children with FS. No differences were found considering miRNA expression between FS type, number of FS experienced.
Conclusions. miRNAs-146a, -181a, -155 and -223 may be involved in FS pathogenesis. Altered miRNA expression levels might be an adaptive response to inflammation. New therapeutic approaches might be developed based on miRNA expressions in children with FS.

Background. The objective of this study was to determine the effect of febrile convulsion (FC) on neuromotor development.
Methods. Data of 325 patients, who were followed up at our outpatient clinic and diagnosed with FC between January 2012 and December 2018, were retrospectively evaluated. Of these patients, 203 underwent the Denver Developmental Screening Test II (DDST II) and were included in the study as the patient group and 100 healthy children as the control group.
Results. Of the study group, 84 (41.4%) were girls and 119 (58.6%) were boys (B/G: 1.4). Of all patients, 163 (80.3%) were diagnosed with simple FC, 22 (10.8%) with complicated FC, and 18 (8.9%) with FC+. There was no significant relationship found between FC subtypes and gender, family history of FC, family history of epilepsy, iron (Fe) deficiency, and Fe deficiency anemia. DDST II subtest points were significantly lower in all developmental areas in the patient group when compared to the controls (p < 0.001), while suspected and abnormal test results were higher in all developmental areas in the patient group compared to the controls (p=0.01). It was also determined that the language points were lower as the age of first seizure increased (r=- 0.319, p < 0.01).
Conclusions. Although FC is known to usually having a good prognosis, the low DDST II test results measured in this study indicated that the FC may pose a developmental risk and patients with FC should be followed up in terms of developmental features. Because of the retrospective nature of the study, there was no `preconvulsion` developmental evaluation. This is a major limitation of our study.

Published: August 2021

Background. Lockdown due to Corona pandemic is an unprecedented event, which has had a profound impact on the lives of children across all ages. Its effects on children with Neurodevelopmental Disorders (NDD) has not been adequately studied. This study was performed in order to explore the effects of lockdown during the Corona pandemic on children with NDD and their parents.
Methods. The survey was conducted in three Indian tertiary-care hospitals wherein parents of children with NDD were requested to respond to an online questionnaire. The questions attempted to elicit various aspects of the children`s therapies and behavioural profiles as well as their parents` experiences during the pandemic related lockdown.
Results. 135/188 (71.8%) parents of children with Autism Spectrum Disorder (ASD)(n=104), Attention Deficit Hyperactivity Disorder (ADHD) (n=26) and Learning Disability (LD)(n=5) responded. Pre-lockdown, 133 (99%) children were receiving regular institution-based therapy, which ceased intra-lockdown. Mean cumulative home-based therapy duration significantly increased during lockdown (p=0.03). Parents reported significantly increased temper tantrums in children (p=0.02). They perceived that during lockdown, their children were bored and their interactions and speech worsened. Majority of parents reported worsening of own qualities of life, but felt confident of taking care of their children during lockdown.
Conclusions. To conclude, children with NDD and their parents were significantly affected by Corona pandemicrelated lockdown. Institutional therapy discontinuation, behavioural deterioration (especially among ASD and ADHD) and parental stress were prominent challenges whereas parental motivation and reliance on homebased therapy were the positive highlights. The survey points to the role of regular parent-administered homebased therapy in children with NDD, especially to tide over similar unexpected adverse scenarios.

This paper examines the effect of per capita income, investment, and unemployment on income inequality in Indonesia from 2011 to 2019. We use both static and dynamic panel data approaches covering 34 provinces in Indonesia. The results support the Kuznets hypothesis, whereby a more significant per capita income growth is associated with more substantial income inequality in a short period; however, this decreases over time (sign change). Furthermore, a larger real per capita income is associated with lower inequality when accompanied by progress in human capital. Alternatively, foreign direct investment (FDI) and infrastructure expenditure positively relate to income inequality, although FDI eventually helps lower inequality. Similarly, increases in domestic private investment can help to reduce income disparity. Meanwhile, unemployment is negatively associated with income inequality, suggesting that better jobs (rather than more jobs per se) are needed to improve income distribution in the country. Although per capita income, investment, and employment have improved substantially and helped Indonesia raise overall income, economic progress does not seem to have been inclusive. We argue that the panel dynamic model helps to capture the persistence effect of income distribution, suggesting a more precise estimation of income inequality issues than static models.

Investing in adult nutrition to reduce mobility problems in ageing population
Authors: Basrowi Ray Wagiu , Koe Levina Chandra , Sundjaya Tonny
Published: August 2021

As people age, most body organs deteriorate. Osteoporosis, arthritis, sarcopenia, muscle aches, low back pain and neuropathy are common mobility issues in the elderly. Body mass index (BMI), physical inactivity, and having comorbidities increase the likelihood to have mobility health problems. One in every ten adults over the age of 45 years in Indonesia develops these mobility problems, and one in every fifteen adults has difficulty in walking/stepping before entering the elderly age. Nutrition has been reported to have important role in controlling weight and physical locomotive organs. Generally, 46% adults in Indonesia have vitamin A deficiency, 70% vitamin C deficiency, 77% vitamin E deficiency, and inadequate calcium intake. Low nutrition intake can result in increasing mobility problems that lead to health issues in the aging population. Dietary strategies are necessary to achieve healthy ageing. Currently, no standardized guideline has been developed for preventing mobility health problems in Indonesia. This calls for urgent need to hinder poor quality of life in elderly population.
A diagnostic test for malnutrition in adults: mid-upper arm circumference towards body mass index: A literature review

Published: August 2021

Body mass index is commonly used for detecting malnutrition. At certain conditions, body mass index cannot be measured, so mid-upper arm circumference can be an alternative measurement for detecting malnutrition. Several studies have proposed the cut-off point of mid-upper arm circumference in adults along with its sensitivity, specificity, and area under the ROC curve (AUC). This article aims to describe the diagnostic test for malnutrition using the upper arm circumference in adults and summarize the results of the related studies.

Physical, mechanical, and decay resistance properties of heat-treated wood by Besson® process of three European hardwood species
Authors: Ninane Maxime , Pollet Caroline , Hébert Jacques , Jourez Benoit
Published: August 2021

Description of the subject. In Europe, the heat treatment of native wood species is gradually becoming an industrial reality. It provides a promising alternative to both the use of naturally durable, essentially tropical woods and the use of chemical preservative treatments based on biocides. Objectives. The aim of this study is to quantify the effect of heat treatment on the physico-mechanical and decay resistance properties of three native hardwood species (oak, ash, beech + steamed beech). Method. The wood was heat-treated in accordance with the Besson® process. The standard physical and mechanical tests including hardness, modulus of elasticity in static bending, static bending, axial compression, splitting and impact bending strengths, have been performed on 15 treated and 15 control associated samples for each species. The standard durability test on fungi exposed 60 treated and 60 control samples to each fungus. Results. The results show a decrease in the equilibrium moisture content and an increase in dimensional stability of heat-treated wood for the three species studied. The modulus of elasticity, hardness and axial compression strength increase slightly after the heat treatment, while static and impact bending strength and splitting strength may considerably decrease. The fungal durability of oak heartwood and ash increased until class 1, beech and steamed beech until class 3. Conclusions. The global approach of this study allows a complete and precise characterization of the technological properties of three native hardwood species after heat treatment. New uses of these native species can thus be explored.

Background: As potentially auto-immune, human papillomavirus vaccination safety surveillance includes Inflammatory Bowel Disease (IBD). We aimed to assess other risk factors among girls scheduled to vaccinate during 2007-2016 Methods: Cohort study including girls aged 9-18 years using the Spanish Primary Care Database for Pharmacoepidemiological Research (BIFAP). Adjusted Hazard ratios (HR; reported in brackets) of IBD associated with (gastroenterological and others) clinical factors were estimated. Results: Out of 388,669 girls, 185 IBD cases occurred (43.78% Crohn’s disease, 37.84% Ulcerative colitis, 18.38% undetermined). IBD increased with age, IBD family history (HR: 10.64), thyroiditis (5.07), herpesvirus infection (4.96), asthenia (1.74), while decreased with inhaled budesonide (0.38) or meningococcus B-C vaccination (0.33). Abnormal bowel movement (25.26), lower gastrointestinal bleeding (8.74), dyspepsia (7.69), abdominal pain (1.49) and spasmolytic (3.89) or antisecretory drugs (2.43) were more recorded among cases. Contraceptives (3.07), fever (2.57), infectious gastroenteritis (2.48), growth problems (2.12), chronic diarrhoea (5.37) and coeliac disease (2.07) showed almost statistical increased risk while depression or allergy showed no risk. Conclusions: The relationship between potential immune diseases and IBD varied, being high for thyroiditis, just suggested for celiac disease and lacking for allergy. The important prevalence of family history, gastrointestinal or growth conditions on IBD was confirmed.

The elderly population, aged above 60 years, are prone to various chronic and concurrent diseases. This requires prolonging medication usage, often with complex regimens which affect their medication-taking behavior, compliance, adherence, and overall prognosis of the disease. Thereby, an accurate assessment of adherence behavior and its complimentary factors, prescription analysis are necessary for effective and efficient treatment planning and an overall improvement in the Health Related Quality of Life (HRQOL) of the elderly population. Our study was aimed to comprehend the HRQOL and medication adherence pattern of the elderly. One hundred and thirty-three subjects with a mean age of 66.68 ± 5.49 years were recruited for the study and were assessed for their HRQOL, medication adherence, and the factors influencing medication adherence. Relevant data were collected, questionnaires were administered, and appropriate descriptive and inferential statistics were performed. Our findings demonstrated that there is a noticeable change in the HRQOL of the elderly population. It was also found that subjects were highly adherent to their medications, but certain factors played a major role in influencing medication non-adherence. This implies the importance of determining factors affecting HRQOL, medication adherence, adequate prescription analysis, and promoting and practicing rational use of drugs that can significantly optimize therapy and provide a good prognosis of disease for the elderly population.

Published: August 2021

Objective: We aimed to the dosimetric analysis of hypofractionated radiation therapy and early clinical results of patients who received breast radiation therapy during the COVID 19 pandemic. Materials and Methods: Seventeen women who received breast cancer radiotherapy were included in the study. For target volumes, the prescription dose was applied 42.55 Gray (Gy) in 16 fractions. COVID-19 symptoms and acute side effects of the patients were followed. Results: Seventeen breast cancer patients were treated with hypofractionated radiotherapy. Dose of 95% of target volumes and critical organ doses were evaluated by normalizing to 50 Gy in 25 fractions. When all plans were evaluated by normalizing to 50 Gy, the maximum dose of medulla spinalis was <45 Gy. The mean dose of heart was <5 Gy. The volume for the lung receiving 20 Gy or more was averaged 20.19. Grade 1 skin reaction was observed in only 5 patients during a mean follow-up of 5 months. Conclusion: In the treatment of breast cancer, hypofractionated radiotherapy is more suitable in terms of shortening the treatment period of patients in the pandemic period and being exposed to less risk. At the same time, the treatment cost is lower as the treatment time is shortened.

Materyal ve Metot: Kesitsel çalışmada, çalışmaya katılan 117 (%73,5) intörn hekimin, anket yanıtları değerlendirilmiştir. Anket, Ulusal Çekirdek Eğitim Programında yer alan temel tıbbi yeterlikler dikkate alınarak dijital form üzerinden hazırlanmış ve WhatsApp grubunda tüm intörnlere ulaştırılmıştır. Bulgular: COVID-19 ön tanısı alan bir hastada, intörn hekimlerin %65’i sistemik fizik muayene yapabileceklerini bildirmişlerdir. İntörnlerin el hijyeni, kişisel koruyucu ekipmanları kurallarına uygun olarak kullanmayı bilme konusunda yeterlik algıları oldukça iyi iken, bulaşıcı hastalıklarda uygulanması gereken izolasyon yöntemlerini (%58,3), alet ve ortamlar için uygun olan dezenfeksiyon, sterilizasyon yöntemlerini (%27,4), hasta odalarının ve eşyalarının temizlik kurallarını (%23,9) bilme konusundaki yeterlik algıları oldukça düşüktü. İntörn hekimlerin %60,7’si, COVID-19 salgını sırasında özellikle mezuniyetlerinin gecikmemesi ve COVID-19 hastalarının takip edilmediği servislerde klinik eğitimlerine devam etmeyi istemekteydi. Sonuç: Tıp eğitiminde, bulaşıcı hastalıklardan korunma yöntemlerinin öneminin kavranması için teorik ve pratik eğitim uygulamalarının artırılması gerektiği düşünülmüştür.

EXPERIMENTAÇÃO NO ENSINO DE QUÍMICA: UMA SEQUÊNCIA DIDÁTICA SOBRE A FORMAÇÃO DA FERRUGEM
Authors: Silva Rafael Soares
Published: August 2021

O ensino de Química quase sempre é desvinculado da realidade limitando-se à memorização de fórmulas e conceitos, dificultando assim o processo de ensino aprendizagem. Essa pesquisa possui uma abordagem metodológica qualitativa (LÜDCKE; ANDRE,1986), amparada pela proposta de experimentação de Giordan (1999), que evidencia a experimentação como uma metodologia alternativa na busca pela contextualização do conteúdo. Foi realizado a aplicação de uma sequência didática adaptada, proposta por Ciscato et al. (2016), sobre a corrosão de objetos metálicos. As atividades experimentais foram realizadas com alunos do 2º ano do Ensino Médio de uma escola pública do Estado de São Paulo. Os resultados apontaram que o experimento auxiliou no ensino e aprendizagem dos conceitos sobre oxirredução, a atividade também possibilitou uma maior interação entre os alunos e uma a melhor compreensão dos conceitos relativos ao tema. Durante as etapas dos experimentos, os alunos se mostraram motivados, estimulando o caráter investigativo, a tomada de decisão e a aprendizagem colaborativa.

У статті проведено аналіз сучасних форматів відеостиснення, наведено та обґрунтовано алгоритм розрахунку необхідного обсягу накопичувача відеореєстратора для надання можливості зберігання даних системи відеоспостереження певний термін, наведено порядок вибору жорсткого диску з точки зору форм-фактора накопичувача, його енергоспоживання та швидкості обертання дискових пластин.

Під час проєктування сучасних систем відеоспостереження необхідно враховувати досить значну кількість чинників. Одними із основних є: тип відеокамер, їх кількість, формат відеостиснення, якість зображення, активність у кадрі, термін зберігання, надійність накопичувача. Перевагою системи відеоспостереження є можливість зберігання відеоданих на необхідний термін з можливістю їх перегляду. Як пристрій зберігання застосовуються SD-карта пам’яті на відеокамері, накопичувач у відеореєстраторі, хмарні технології. У статті розглядаються питання збереження даних на жорсткому диску відеореєстратора. На сьогоднішній день широкого застосування набули як аналогові, так і цифрові або IP-відеокамери, які відрізняються принципами формування відеосигналу і можливостями підключення до мережі. Кількість відеокамер визначається характеристиками і параметрами об’єкта, що охороняється. Кожна сучасна IP-відеокамера підтримує декілька форматів стиснення даних, які різняться за принципами дії, коефіцієнтом стиснення, якістю зображення, а для аналогових відеокамер стиснення проводиться у відеореєстраторі. Ці фактори у кінцевому підсумку впливають на необхідний загальний обсяг пам’яті відеореєстратора. Крім цього, значущим є забезпечення надійності накопичувача, особливо для спостереження за важливими об’єктами.
