Background: Haemophilia A is a bleeding disorder caused by inadequate clotting factor VIII (FVIII). There are two main modes of treatment approach in severe haemophilia A patients either with on-demand or prophylaxis therapy with clotting factor FVIII concentrates. In this study, a comparison was made between the bleeding incidence rate of the on-demand and prophylaxis group in severe haemophilia A patients at Ampang Hospital, Malaysia. Methods: A retrospective study involving patients with severe haemophilia was conducted. The patient’s self-reported bleeding frequency was retrieved from the patient’s treatment folder from January to December 2019. Results: Fourteen patients received on-demand therapy, while the other 24 patients received prophylaxis treatment. The total number of joint bleeds in the prophylaxis group was significantly lower compared to the on-demand group (2.79 bleeds versus 21.36 bleeds [P < 0.001]). Furthermore, the total annual usage of FVIII was higher in the prophylaxis group compared to the on-demand group (1,506 IU/kg/year [± 905.98] versus 365.26 IU/kg/year [± 223.90], P = 0.001). Conclusion: Prophylaxis FVIII therapy is an effective treatment in reducing the frequency of bleeding joints. However, this treatment approach is associated with high cost due to the high consumption of FVIII.

Globally, heart failure with preserved ejection fraction (HFpEF) is quickly becoming the dominant form of heart failure (HF) in ageing populations. However, there are still multiple gaps and challenges in making a firm diagnosis of HFpEF in many low-to-middle income Asian countries. In response to this unmet need, the Malaysian HFpEF Working Group (MY-HPWG) gathered and reviewed evidence surrounding the use of different diagnostic modalities indicated for patients with HFpEF to identify diagnostic tools that could be conveniently accessed across different healthcare settings. As a result, five recommendation statements were proposed and an accompanying algorithm was developed, with the aim of improving the diagnostic rate of HFpEF. The MY-HPWG recommends using more easily accessible and non-invasive tools, such as natriuretic peptide (NP) biomarkers and basic echocardiogram (ECHO), to ensure timely HFpEF diagnosis in the primary and secondary care settings, and prompt referral to a tertiary care centre for more comprehensive assessments in uncertain cases.

Background: Head and neck cancer patients usually need nutritional support due to difficulties in swallowing and chewing. Therefore, this study aimed to formulate Musa paradisiaca and Trigona sp. honey jelly (MTJ) as a convenient functional food. Methods: The antioxidant properties were analysed using 2,2′-diphenyl-1 picrylhydrazyl (DPPH), ferric reducing antioxidant potential (FRAP) and 2,2′-azinodi 3-ethylbenthiazolinesulfonate (ABTS) assays. Cytotoxicity was assayed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) test and the induction of apoptosis was observed via caspase-3/7 activity assay. The identification of phenolic compounds was done via ultra-high-performance-liquid chromatography coupled to mass spectrometer (UHPLC-MS/MS). Results: The antioxidant analysis exhibited: the half inhibitory concentration (IC50) of DPPH inhibition, 54.10 (SD = 4.51) µg/mL; the FRAP value, 30.07 (SD = 0.93) mM TEQ/100 g; and the ABTS value, 131.79 (SD = 8.73) mg TEQ/100 g. Cinnamic acid was the most abundant phenolic compound, followed by maleic acid and salicylic acid. The IC50 for ORL115 and ORL188 were 35.51 mg/mL and 43.54 mg/mL, respectively. The cells became rounded and dissymmetrical which reduced in number and size. The apoptotic cell death in ORL115 and ORL188 was deduced as caspase-3/7 activities that significantly increased (P < 0.05). Conclusion: The study evidenced that the antioxidant activity of MTJ could influence the induction of apoptosis in ORL115 and ORL188 in future investigations and verifications.
Displaced Abomasum
Authors: Pehrson Bo G. , Shaver Randy D.
Published: March 2023

Incidence of displaced abomasum (DA) in dairy cows is at least 10 times higher in Wisconsin herds than in Sweden, even though average fat-corrected milk production levels are similar. In southern Wisconsin an incidence of 2.5-3.5% appears normal (Dr. Rhoda, personal communication, Evansville, WI).

Feed ingredient and breed differences may be associated with different incidence rates between countries. However, a preliminary investigation (Pehrson, unpublished) indicated that Wisconsin feeding and management practices during the peripartal period may be closely associated with the high incidence rate. The primary objective of the present study was to further evaluate this hypothesis (Trial B). A secondary objective was to collect clinical data with regard to occurrence of DA in the same geographic area (Trial A).
Intensive Rotational Grazing in the Dairy Industry
Authors: Muller L. D. , Holden L. A.
Published: March 2023

Pastures had been a significant feature of theAmerican landscape for centuries, and were used as themajor source of nutrients for dairy cows. Many studiesin the early 1900s focused on agronomic and pasture productivity, pasture management, animal responses, and economic factors (Fales, et al., 1992), and scientists in the United States were considered leaders in pasture research and education. The movement away from pasture systems toward "confined" systems began in the 50s and was caused by many economic, political, and technological factors. Research and education programs related to pasture declined dramatically, and pasture use declined in Pennsylvania from about 170 days per year in the early 1950s to 64 days (mainly exercise lots) in 1990. Pasture systems based on early United States research were adopted widely in various countries of Europe and in New Zealand, and these countries are now considered the world leaders in intensive pasture systems.
Feedlot Respiratory Disease
Authors: Griffin Dee , Perino Louis , Wittum Thomas
Published: March 2023

Despite the development of new vaccines, and therapeutics, bovine respiratory disease (BRD) continues to be the primary health problem of feedlot cattle. Assessment of the entire feeding performance loss associated with BRD has not been studied. The Texas Ranch to Rail program includes the entire feeding disease loss. Their findings will be reviewed. Intervention of BRD includes the use of vaccines and timely therapeutics. Effort is given in feedlots to have properly trained employees daily evaluate the health of cattle in the belief that well timed therapy will alter the course of BRD. This paper will review two research projects designed to evaluate BRD intervention in ranch fresh weaning calves.
Factors to Concentrate on to Prevent Periparturient Disease in the Dairy Cow With Special Emphasis on Milk Fever
Authors: Goff J. P. , Horst R. L.
Published: March 2023

Efficient milk production continues to require the dairy cow to experience gestation and parturition each year. The transition from pregnant, non-lactating to non-pregnant, lactating is too often a disastrous experience for the cow. Most of the metabolic diseases of dairy cows - milk fever, ketosis, retained placenta, and displacement of the abomasum - occur within the first 2 weeks (wk) of lactation. The etiology of many of those metabolic diseases that are not clinically apparent during the first 2 wk of lactation, such as laminitis, can be traced back to insults that occurred in early lactation. In addition to metabolic disease, the overwhelming majority of infectious diseases, especially mastitis, but also diseases such as Johne's disease and Salmonellosis, become clinically apparent during the first 2 wk of lactation. The well-being of the cow and her profitability could be greatly enhanced by understanding those factors that account for the high disease incidence in periparturient cows.

Three basic physiologic functions must be maintained during the periparturient period if disease is to be avoided. These are: 1. adaptation of the rumen to high energy density lactation diets to reduce the degree of negative energy balance experienced by the cow; 2. maintenance of normocalcemia; and 3. reducing the degree of immunosuppression that occurs around parturition. Both metabolic disease and infectious disease incidence are greatly increased whenever one or more of these physiological functions is impaired. The etiological role of each of these three physiological factors on the development of each of the common diseases encountered during the periparturient period is discussed more fully in reference.17 A brief discussion of the etiology of several important periparturient diseases is presented below.

Does it Pay to Use an Ultrasound Machine for Early Pregnancy Diagnosis in Dairy Cows?
Authors: DesCôteaux Luc , Fetrow John
Published: March 2023

Pregnancy diagnosis is regarded as an important and necessary component of a complete dairy herd health program (Olternacu et al. , 1990). The main objective of such a comprehensive program is to make sure that healthy productive cows calve at 12-13 month intervals to optimize their life milk production. Seegers and Malher (1996) reported that every open day past 100 days in milk costs between $2.50 and $4.00 to dairy producers. Early pregnancy diagnosis can assist dairymen in managing open cows and improving reproductive performance and economics of their herd (Olternacu et al., 1990).
Deconstruction. Critical Interventions for the 21st Century and Beyond
Authors: Gunkel David J.
Published: March 2023

This essay seeks to make a case for deconstruction as a kind of critical intervention for responding to and dealing with the opportunities and challenges of the 21st century and beyond. Toward this end, it proceeds in three steps or movements. (1) The first part will deconstruct deconstruction, deliberately employing what will be revealed as an inaccurate vernacular understanding of the term in order to extract a more precise and technical characterization of the concept. (2) The second part will investigate the constitutive elements of deconstruction, focusing attention on its two-step procedure, which has been deliberately designed to be a kind of distortion of Hegelian dialectics. (3) Finally, the third part will examine the opportunities and the challenges of the theory and practice of deconstruction indicating how and why it can be considered a critical intervention, albeit one that is not without its own potential problems and vulnerabilities.

Zawiera omówienie następujących zagadnień: geneza filozofii osoby u K. Wojtyły, jego epistemologia i metafizyka osoby, stanowisko w kwestiach świadomości, emocji, działania i godności osoby. Wieloaspektowość i wszechstronność opracowanych zagadnień pozwalają nie tylko zrekonstruować personalistyczną teorię K. Wojtyły, ale również wytyczyć kierunki jej dalszego rozwoju – metafizykę osoby, analizę fenomenologiczną, osoba w kontekście neuronauk. Do tych kierunków można dodać teorię sieci społecznych. Narzędzie to pozwoliłoby na poszerzenie teorii personalistycznej o społeczny, praktyczny wymiar relacji międzyludzkich i praktyczną analizę fenomenów takich, jak np. wolność, odpowiedzialność, solidarność, miłość czy sprawiedliwość. Wyniki tych badań mogłyby uzupełnić filozofię osoby o płaszczyznę społeczną.

Metal Matrix Nanocomposites: A Brief Overview
Authors: Sarode Prashil U. , Raul Jhantu G. , Gaikwad Aditya S. , Gawande Shravan
Published: March 2023

The need for lightweight materials is increasing at a faster rate in the engineering field. It demands
materials with high strength, low weight, and properties like ductility and formability which are
required for easier processing of the material. When conventional pure metals and alloys failed to meet
this demand, many researchers turned their attention toward developing composites. Composites can be
fabricated from metal, polymer, and ceramic as base materials which are known as metal matrix composites
(MMC), polymer matrix composites (PMC), and ceramic matrix composites (CMC), MMC are of
special importance due to properties like strength, stiffness, and formability which are difficult to obtain
from PMC and CMC. Even though conventional composites with micron-size reinforcement have enhanced
certain properties like strength, hardness, and wear resistance, it deteriorated other desirable properties
like ductility. To overcome these limitations of micro-composites, a new category of materials
known as nanocomposite has been developed. Nano composites are materials that contain nano-scale
reinforcement in different forms. This review article summarizes the recent progress in the field of metal
matrix Nano composite (MMNC). Methods of fabrication which are applicable for metal alloys and micro-
composites are mostly not suitable for nanocomposite fabrication, the recently developed fabrication
process which are applicable for MMNC’s are discussed in this article. The effects of added nano reinforcement
on the microstructure are also discussed with suitable examples. Enhancements in mechanical,
tribological, and physical properties are explained in depth with the help of recently published data.
Strengthening mechanisms are described with the help of empirical relations. Although industrial applications
of metal matrix nano composites are limited due to the ongoing developments in this field, a few
important potential application areas are also discussed at the end of this article.
Design and Characterization of Smart Supramolecular Nanomaterials and their Biohybrids
Authors: Vijayan Jyothy G.
Published: March 2023

Over the past few years, much effort has been taken to explore the
applications of nanoparticle-based structures in different fields such as nanomedicine,
molecular imaging, etc.. Supramolecular analytical methods have attracted researchers
due to their chemical formula, flexibility, convenience, and modularity for the
synthesis of nanoparticles. The incorporation of functional ligands on the surface of
supramolecular nanoparticles helps to improve their performance in many areas.
Fabrication of supra molecular materials with uniform size gives more advantages of
using them in different fields. Characterization techniques like positron emission
tomography imaging (PET), magnetic resonance imaging (MRI), fluorescence studies,
scanning electron microscopy (SEM), and UV-Vis studies help to identify the
molecular images and structure effectively. Supramolecular systems are used as an
effective technique in the nano-design of supramolecular nano-systems. They enhance
the solubility, modification of surface properties, bioconjugation of nanoparticles due
to the supramolecular recognition properties, and supramolecular materials that are
applied for the removal of targeted molecules. The designing process makes it able to
function in complex matrices. This chapter discusses the design, synthesis and
characterization of supramolecular nanostructures and their hybrids and also discusses
their application in different fields.

crystalline carbon nanomaterial, as well as the most flexible, strongest, and toughest.
The widespread application of graphene demonstrates its huge potential in a variety of
industries, along with photovoltaic cells, electrochemical, optoelectronics, electronics,
microelectronics, intelligent gadgets, extensible supercapacitor electrodes, aerospace,
smart sensors, and analytical chemistry. The commercialization of graphene will be
vital to the future of an industrially viable method of producing and processing
graphene. Nanotechnologies based on graphene are gaining prominence in
environmental and energy applications. Graphene has exceptional physicochemical
properties, including high surface area, chemical resistance, heat capacity, mechanical
characteristics, and charge transport. It might be used in environmental remediation,
water purification, and desalination filters, as an electrocatalyst for contamination
sensing. A broad literature collection will also be provided on graphene technology,
including graphene characteristics, production processes, and uses. Graphene is the
most popular carbon-based material, with excellent unique advantages such as high
electrical conductivity, high tensile strength, high thermal conductivity, high carrier
mobility, and transparency, making it a compelling candidate for a variety of
applications such as sensors, transistors, energy storage, water purification membranes,
solar cells, and elastomers. Although development in graphene-based nanomaterials for
devices is encouraging, certain important issues such as long-term stability, toxicity,
and environmental impacts remain unresolved. In this chapter, we assess recent
advances in graphene research and applications and also attempt to predict where the
field might go in the future.

Published: March 2023

Purpose This research aimed to determine the effect of the effective tax rate in public company investment in Indonesia. Design/methodology/approach The research was conducted using firm data during 2008-2020 and considered the long-term investment concept. Meanwhile, the cross-section of 672 companies and the ordinary least square technique were used to get the estimation. Findings The estimation result showed that the effective tax rate has significant negative effect on fixed asset investment. If effective tax rate decrease, it can be because the company gets tax rate reduction incentives, conduct accelerated depreciation, fiscal reconciliation on the financial statement which can increase fixed asset investments. Moreover, the estimation also showed that the age of the company is able to strengthen the relationship between effective tax rate and company investment. The difference in domestic and foreign companies does not affect the elasticity ETR toward investment. Research limitations/implications Based on the estimation result mentioned, it is expected to provide guidance in implementing incentive tax, which can encourage public company investment. Originality/value There are many studies on the effect of income tax rates, but the results cannot be used specifically in Indonesia since the tax sensitivity may be different based on the development level of the country and the characteristics of the company.

Spillway rehabilitation planning aims to determine the discharge of major floods, dimensional design of the structure, and analyze the stability. This planning was carried out at the Takisung Retarding basin, Tanah Laut Regency, South Kalimantan. The initial stage of this planning is to review in detail the incoming discharge that enters the reservoir which is then used for flood routing on the spillway. The result of flood routing is in the form of outflow which will be used as the basis for planning the spillway, the water level profil, and the planning of the stilling basin. The result of the planning is a large discharge using the HSS Nakayasu method as an inflow discharge with a return period of 100 years and a return period of 1000 years as the control. Inflow discharge of Q100th = 61,729 m3/second; Q1000th = 72,541 m3/second and an outflow discharge of Q100th = 30,453 m3/second; Q1000th = 37.767 m3/second. Then the spillway planning results are in accordance with the conditions of the study area from topography, hydrology and hydraulics using Q100th. Analyze of the stability with the load with empty water, normal water level in normal and earthquake conditions, and flood water level with Q1000th discharge and extreme conditions which results in safety against overturning, shearing and soil carrying capacity not exceeding the allowable stress of the soil so that it meets the requirements.

Published: March 2023

In this paper, a new proposal for a nonlinear edge-preserving interpolator and hardware implementation is presented. As a new idea for a color image interpolator, our proposal is focusing on the interpolated pixel and we tried to adjust it in order to have better quality. To evaluate the effectiveness of the proposed idea for preserving images, we implemented it using different color images and we evaluated using different evaluation measurements. Then, we compared our new proposal with the traditional nonlinear Edge preserving interpolator. The obtained results confirm that our proposed Edge preserving is better than the old interpolator. It also demonstrates consistent image quality performance among a variety of images. The hardware implementation based on FPGA shows that we are able to gain image quality without increasing the size of the circuit once implemented in hardware. We show that our proposed interpolator for Edge preserving improves considerably the image quality and represents a fast solution when implemented in hardware. Despite a small increase in FPGA resources, we obtain an average improvement of the image quality of about 35.75% using the NCD metric.

Published: March 2023

This descriptive-correlational study aims to determine the level of employee commitment and performance of the faculty members of Montfortian educational institutes in Southeast Asia having locale, employment status, educational attainment, and years of service as the selected variables for analysis. The randomly selected sample respondents for the study were the 81 teachers employed in two Montfortian Educational Institutions in Southeast Asia. The level of commitment was measured in three dimensions: Affective commitment, continuance commitment, and normative commitment. The level of performance was measured using four dimensions: Knowledge of the subject matter, knowledge of the nature of the learners, professionalism, and community engagement. Statistical analysis was made using the T-test and ANOVA. The findings of the study showed a “Very High” level of commitment of the faculty members both taken as a whole and when classified according to the selected variables. The exception is the level of continuance commitment among those who have served the school for more than 20 years. The level of performance was found to be “Very Good,” although it varied from “Very Good” to “Excellent” when analyzed by variables. A “Moderate Significant Relationship” between the levels of commitment and the levels of performance was established. The “locale” of the respondents significantly made a difference in the levels of commitment and in the relationship between the level of commitment and the level of performance. The result of the study shall be the basis for the formulation of a faculty development program to address the perceived gaps based on the findings of the research study.

Background

Patients with high myopia have an increased lifetime risk of complications. The prevalence patterns of high myopia in children and adolescents in southern China are unclear. Early identification of high-risk individuals is critical for reducing the occurrence and development of high myopia and avoiding the resulting complications.

Objective

This study aimed to determine the prevalence of high myopia in children and adolescents in southern China via real-world screening data and to predict its onset by studying the risk factors for high myopia based on machine learning.

Methods

This retrospective school-based study was conducted in 13 cities with different gross domestic products in southern China. Through data acquisition and filtering, we analyzed the prevalence of high myopia and its association with age, school stage, gross domestic product, and risk factors. A random forest algorithm was used to predict high myopia among schoolchildren and then assessed in an independent hold-out group.

Results

There were 1,285,609 participants (mean age 11.80, SD 3.07, range 6-20 years), of whom 658,516 (51.2%) were male. The overall prevalence of high myopia was 4.48% (2019), 4.88% (2020), and 3.17% (2021), with an increasing trend from the age of 11 to 17 years. The rates of high myopia increased from elementary schools to high schools but decreased at all school stages from 2019 to 2021. The coastal and southern cities had a higher proportion of high myopia, with an overall prevalence between 2.60% and 5.83%. Age, uncorrected distance visual acuity, and spherical equivalents were predictive factors for high myopia onset in schoolchildren. The random forest algorithm achieved a high accuracy of 0.948. The area under the receiver operator characteristic curve (AUC) was 0.975. Both indicated sufficient model efficacy. The performance of the model was validated in an external test with high accuracy (0.971) and a high AUC (0.957).

Conclusions

High myopia had a high incidence in Guangdong Province. Its onset in children and adolescents was well predicted with the random forest algorithm. Efficient use of real-world data can contribute to the prevention and early diagnosis of high myopia.

Technological development and the reduction of installation costs have caused a rapid growth of solar power plants in Indonesia. The National Electricity Company (Perusahaan Listrik Negara, PLN) strives to achieve the energy mix of renewable energy to 23% by 2025. Solar power plants are unique in that they only supply their power during the daytime. It makes solar power plants connected to the power system change the load profile of the Java-Bali system. In this study, the penetration of solar power plants changed the scheduling of the Java-Bali system because the penetration was installed to the technical minimum loading of existing power plants. When penetration is too big, thermal generator scheduling failure is possible. Unit commitment and economic dispatch with mixed-integer linear programming (MILP) method using CPLEX and Python were carried out to calculate the fuel and generation costs per kWh before and after the penetration. MILP was used to solve the cost fuel equation, namely an integer and nonlinear mix equations, that are challenging to be solved using standar nonlinear programming methods. Due to the use of the MILP-UC, all objective function equations and restraint functions must be linear functions. The tests were conducted for three years, from 2023 to 2025. Simulation results on the Java-Bali system show that the capacity of solar power plants penetrating the Java-Bali system against the peak load will be 52%, 52%, and 50% in 2023, 2024, and 2025, respectively. Meanwhile, penetration of solar power plants to technical minimum loading of existing power plants resulted in the fuel cost falling by 23% in 2023 and 22% in 2024 and 2025. Lastly, the cost of generation per kWh will be decreased by 8% in 2023 and will be as low as 7% in 2024 and 2025.

Salah satu peralatan medis yang sering digunakan di rumah sakit adalah infus. Namun, sampai saat ini sistem monitoring infus pada umumnya masih bersifat manual. Petugas medis harus memperhatikan kondisi alat infus secara kontinu, sehingga membutuhkan tenaga dan waktu yang lebih. Pada penelitian ini, dikembangkan sebuah sistem monitoring cairan infus Ringer Lactate 500 ml untuk pasien berbasis internet of things (IoT) menggunakan protokol komunikasi message queuing telemetry transport (MQTT) dan sistem cloud server IoT menggunakan MQTT Dash. Cairan infus jenis Ringer Lactate 500 ml dipilih karena infus jenis tersebut paling banyak digunakan. Sensor yang digunakan adalah load cell HX711. Sistem yang dikembangkan dalam penelitian ini terdiri atas beberapa perangkat keras dan perangkat lunak utama. Perangkat keras yang pertama ada mikrokontroler NodeMCU ESP8266. Mikrokontroler ini digunakan karena sudah dilengkapi modul ESP8266 yang merupakan modul WiFi, sehingga mendukung penerapan sistem IoT. Kemudian, sensor yang digunakan adalah load cell HX711 untuk mengetahui berat cairan infus. Untuk pengiriman data ke pengguna, digunakan protokol MQTT yang kemudian terhubung dengan aplikasi MQTT Dash sebagai media monitoring bagi petugas medis. Kinerja sistem diamati berdasarkan kinerja sensor load cell HX711. Ditinjau dari pembacaan berat cairan infus, hasil menunjukkan akurasi yang sangat baik, dibuktikan dengan nilai rata-rata persentase error 0,08% sampai dengan 0,64%. Sensor load cell HX711 bekerja dengan baik karena error pembacaan masih dalam batas toleransi error pembacaan sensor load cell, yaitu 5%. Pengujian quality of service (QoS) menunjukkan bahwa rata-rata delay pada semua sistem adalah 0,014 ms sampai dengan 0,023 ms. Nilai tersebut tergolong sangat bagus berdasarkan standar telecommunications and internet protocol harmonization over network (TIPHON). Kemudian, dari hasil pengujian packet loss pada semua sistem diperoleh rata-rata sebesar 0% sampai dengan 0,01%. Nilai tersebut tergolong sangat bagus berdasarkan standar TIPHON.

The ability to inhibit corrosion of low carbon steel in a salt solution (3.5%NaCl) has been checked with three real expired drugs (Cloxacillin, Amoxicillin, Ceflaxin) with variable concentrations (0, 250, 500, 750) mg/L were examined in the weight loss. The inhibition efficiency of the Cloxacillin 750 mg/L showed the highest value (82.8125 %) and the best inhibitor of the rest of the antibiotics. The different concentrations of Cloxacillin drug (0, 250, 500, 750) mg/L and temperature (25, 35, 45, 55) oC were studied as variables with potentiodynamic polarization, Scanning Electron Microscopy (SEM) for surface morphology and electrochemical impedance spectroscopy (EIS) depending on current values and the resistance of charge to calculate the inhibition efficiency. The main observations of these tests were that polarization curves showed a mixed-type inhibition of expired Cloxacillin. The inhibition efficiency increased with increasing Cloxacillin concentration but not with increasing temperature.

In this study, the mechanical properties of an epoxy and unidirectional woven carbon with fiberglass composite were experimentally investigated. When preparing the composite samples, American Society for Testing and Materials (ASTM)standard was used. Tensile, impact and flexural test were conducted to investigate the mechanical properties of the new produced epoxy Unidirectional Woven Carbon and Epoxy Fiberglass composites. The outcome showed that the strength of the produced samples increased with the increase in the number of unidirectional woven carbon layers added. Two methods were utilized: (1) woven carbon composite with glass fiber (2) woven carbon composite). The two methods of composite were compared with each other.  The results explained that woven carbon composite had  higher mechanical resistance. While  in impact test the toughness of the sample  increased with adding layers of mixture of Fiber glass with unidirectional woven carbon and epoxy.

В качестве одного из перспективных направлений дальнейшего развития сетей доступа следует выделить сценарии комплексного использования их ресурсов. Словосочетание "комплексное использование ресурсов сетей доступа" используется как общее понятие для трех задач, перекликающихся между собой. Первая заключается в совместном использовании несколькими телекоммуникационными операторами разных компонентов сети доступа. Совместная модернизация и эксплуатация инфраструктурных сооружений, предназначенных для систем связи, электроэнергетики и других коммунальных служб на уровне сети доступа, рассматривается как вторая задача. Третья задача − задействование ресурсов сети доступа при возникновении экстраординарных событий.
