Characterisation and Manipulation of Polarisation Response in Plasmonic and Magneto-Plasmonic Nanostructures and Metamaterials
Authors: Khan Pritam , Brennan Grace , Lillis James , Tofail Syed A. M. , Liu Ning , Silien Christophe
Published: August 2020

Optical properties of metal nanostructures, governed by the so-called localised surface plasmon resonance (LSPR) effects, have invoked intensive investigations in recent times owing to their fundamental nature and potential applications. LSPR scattering from metal nanostructures is expected to show the symmetry of the oscillation mode and the particle shape. Therefore, information on the polarisation properties of the LSPR scattering is crucial for identifying different oscillation modes within one particle and to distinguish differently shaped particles within one sample. On the contrary, the polarisation state of light itself can be arbitrarily manipulated by the inverse designed sample, known as metamaterials. Apart from polarisation state, external stimulus, e.g., magnetic field also controls the LSPR scattering from plasmonic nanostructures, giving rise to a new field of magneto-plasmonics. In this review, we pay special attention to polarisation and its effect in three contrasting aspects. First, tailoring between LSPR scattering and symmetry of plasmonic nanostructures, secondly, manipulating polarisation state through metamaterials and lastly, polarisation modulation in magneto-plasmonics. Finally, we will review recent progress in applications of plasmonic and magneto-plasmonic nanostructures and metamaterials in various fields.
Bound Electron Transitions under the Influence of Electromagnetic Wave in Constant Magnetic Field
Authors: Zhukovsky Vladimir
Published: August 2020

Motion and radiative transitions of an electron in a magnetic field under the influence of an external electromagnetic wave are studied for various confining conditions in semiconductor, graphene, in quantum wells, and relativistic generalization in terms of the Klein–Gordon equation are considered. In particular, the following problems are discussed. The so-called cyclotron resonance, which may appear in graphene, is studied with indication for appearance of the so-called frequency-halving. The problem is solved for two-dimensional massless charged particle, whose gapless nature is protected by sublattice symmetry. The exact classical calculation of this effect is undertaken in the framework of a 2D classical equation for a zero-mass electron. We also find an exact solution of the Schrödinger equation for charge carriers in semiconductors under the influence of an external magnetic field and in the field of electromagnetic wave with an account for their radiative transitions. Solutions of the relativistic Klein–Gordon equation in this configuration of electromagnetic fields are found as a certain generalization of the results obtained for the non-relativistic case. These results may serve as a first step for further efforts to find exact solutions of wave equations for quasiparticles in solid state structures in external fields.

Genome sequencing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is increasingly important to monitor the transmission and adaptive evolution of the virus. The accessibility of high-throughput methods and polymerase chain reaction (PCR) has facilitated a growing ecosystem of protocols. Two differing protocols are tiling multiplex PCR and bait capture enrichment. Each method has advantages and disadvantages but a direct comparison with different viral RNA concentrations has not been performed to assess the performance of these approaches. Here we compare Liverpool amplification, ARTIC amplification, and bait capture using clinical diagnostics samples. All libraries were sequenced using an Illumina MiniSeq with data analyzed using a standardized bioinformatics workflow (SARS-CoV-2 Illumina GeNome Assembly Line; SIGNAL). One sample showed poor SARS-CoV-2 genome coverage and consensus, reflective of low viral RNA concentration. In contrast, the second sample had a higher viral RNA concentration, which yielded good genome coverage and consensus. ARTIC amplification showed the highest depth of coverage results for both samples, suggesting this protocol is effective for low concentrations. Liverpool amplification provided a more even read coverage of the SARS-CoV-2 genome, but at a lower depth of coverage. Bait capture enrichment of SARS-CoV-2 cDNA provided results on par with amplification. While only two clinical samples were examined in this comparative analysis, both the Liverpool and ARTIC amplification methods showed differing efficacy for high and low concentration samples. In addition, amplification-free bait capture enriched sequencing of cDNA is a viable method for generating a SARS-CoV-2 genome sequence and for identification of amplification artifacts.
Removal of Cadmium from Contaminated Water Using Coated Chicken Bones with Double-Layer Hydroxide (Mg/Fe-LDH)
Authors: Alquzweeni Saif S. , Alkizwini Rasha S.
Published: August 2020

Occurrence of heavy metals in freshwater sources is a grave concern due to their severe impacts on public health and aquatic life. Cadmium (Cd2+) is one of the most dangerous heavy metals, and can cause serious diseases even at low concentrations. Hence, a wide range of treatment technologies exist, such as nanofiltration and biological reactors. In this context, the present investigation aims at the development of a new adsorption medium, made from chicken bones coated with iron (Fe) and magnesium (Mg) hydroxides, to remove cadmium from water. This novel chicken bone functional substance was manufactured by applying layered double hydroxides (LDH) into the chicken bones. Initially, the new adsorption medium was characterized using Fourier-transform infrared spectroscopy (FTIR technology), then it was applied to remove cadmium from water under different conditions, including pH of water (3–7.5), agitation speed (50–200 rpm), adsorbent dose (1–20 g per 100 mL), and contact time (30–120 min). Additionally, the reaction kinetics were studied using a pseudo-first order kinetic model. The results obtained from the present study proved that the new adsorption medium removed 97% of cadmium after 120 min at an agitation speed of 150 rpm, pH of 5, and adsorption dose of 10 g per 100 mL. The results also showed that the new adsorption medium contains a significant number of functional groups, including hydroxyl groups. According to the outcomes of the kinetic study, the mechanism of removing metal is attributed to surface precipitation, ion exchange, complexation, hydrogen binding between pollutants, and the LDH-chicken bone substance.

Published: August 2020

We present and assess a method to estimate missing values in daily precipitation time series for the Mediterranean island of Crete. The method involves a quantile mapping methodology originally developed for the bias correction of climate models’ output. The overall methodology is based on a two-step procedure: (a) assessment of missing values from nearby stations and (b) adjustment of the biases in the probability density function of the filled values towards the existing data of the target. The methodology is assessed for its performance in filling-in the time series of a dense precipitation station network with large gaps on the island of Crete, Greece. The results indicate that quantile mapping can benefit the filled-in missing data statistics, as well as the wet day fraction. Conceptual limitations of the method are discussed, and correct methodology application guidance is provided.
Des premiers jours de guerre dans la région de Verviers (3-8 août 1914) relatés par le soldat Gabriel Vercken... au Service de correspondance et de documentation de Joseph de Dorlodot (1915-1919). Histoire(s) et destins croisés
Authors: Tallier Pierre-Alain
Published: August 2020

In the autumn of 1916 the Belgian soldier Gabriel Vercken makes contact with Joseph de Dorlodot, head of the “Service of correspondence and documentation” based in Folkestone. A native of Verviers, he relates of having closely witnessed the events that took place in his hometown and its region during the first days of the war and proposes to establish an account.

The publication of this unpublished manuscript addresses three principal concerns. Firstly, Gabriel Vercken’s text, while unfinished, provides very accu¬ rate indications with regard to the events that he came to report during the first days of the war and makes an a posteriori, but undeniable contribution to testimonies that have already been published. It not only confirms a number of elements known among specialists, but also contains new information on the psychosis of the “free shooters” and the wrongdoings committed by the 14th German infantry brigade in the region of Verviers (Verviers, Battice, Fécher, Herve, Micheroux, Soiron et Soumagne).

Secondly, it is important to point out that the archives of the “Service of correspondence and documentation” contain a huge number of other manus¬ cripts on the events that occurred in Belgian municipalities during the first days of the war, whose volume and importance compare to Gabriel Vercken’s text.

Finally, one should highlight the precise nature and the extreme diversity of activities deployed by Joseph de Dorlodot’s “Service of correspondence and documentation”, the various ramifications of which have not yet been covered at present.

Published: August 2020

Pasal dalam KHI yang mengatur perceraian terbilang relevan dalam upaya mendamaikan hubungan pernikahan. Di sisi lain, pasal tersebut seakan-akan dapat menimbulkan kesenjangan hukum (conflict of norm) antara keputusan hukum islam dan hukum positif. Seperti contoh, dalam hukum islam, talak menjadi hak otoritatif suami, kapanpun suami mengucapkan talak kepada istrinya maka ucapan tersebut sudah dianggap jatuh. Berbeda dengan pasal yang ada dalam KHI, (pada pasal 115, 117 dan 123) disebutkan bahwa perceraian hanya bisa terjadi jika dilakukan ikrar di depan persidangan majelis hakim Pengadilan Agama. Dalam penelitian ini, ada dua hal penting yang diteliti yaitu pandangan hakim Pengadilan Agama Kabupaten Malang dan Kyai PPS Shirothul Fuqoha’ serta pandangan keduanya ditinjau dari perspektif Mashlahah Imam As-Syatibi.

Grant practice is a transaction that is commonly done by the community. Apart from that, the grant is a sunnah work that is highly recommended carried out by Muslims. The Compilation of Islamic Law (KHI) and the Civil Code (KUHPerdata/BW) have governed the implementation of grants in Indonesia.

basically the purpose of the grant between husband and wife to improve the quality of family relationships that love each other. However, not all good intentions and objectives have good consequences, moreover the actions taken are not based on careful calculation. Grants between husband and wife in the Compilation of Islamic Law are permitted. That is because there are no provisions that state who is entitled or not entitled to receive or give grants. While regarding the grants between husband and wife, the Civil Code said differently. In the Civil Code, grants between husband and wife during marriage are prohibited.

Kerala has an enormous tradition on Tantra literature and also has different kinds of ritual peculiarities between Brahmanical and non-Brahmanical rituals. Most of the Tantra ritual manuals of Kerala focus the temple rituals and concomitant subjects too. Philosophical discussions are not much can be seen in Kerala Tantra manuals. There are many texts on Kerala Tantra that still remain in manuscripts from. The Mātṛsadbhāva is one among them, which discuss the ritual of Goddess Bhadrakālī/ Camuṇḍā along with Sapta-mātṛs, Śiva and Kṣetrapāla. The text is believed as the first Śākta text from Kerala. The text has twenty-eight chapters, begins from ācāryalakṣaṇa to ends in jīrṇodhāra. The text has a strong connection with South Indian Brahmayāmala and the author of Mātṛsadbhāva refer to Brahmayāmala many times. The present study is focusing on the special features of Tantra literature of Kerala and a special discussion on Mātṛsadbhāva along with Brahmayāmala and Śeṣasamuccaya.
A Reliable Communication Framework and Its Use in Internet of Things (IoT)
Authors: Alam Tanweer
Published: August 2020

Peoples are naturally communicators but devices
are not. In the Internet of Things (IoT) architecture, the smart devices (SDs),
sensors, programs and association of smart objects are connected together to
transfer information among them. The SD is designed as physical device linked
with computing resources that are capable to connect and communicate with
another SD through any medium and protocol.
The communication among intelligent physical things is a challenging task
to exchange information that guaranteed to reach to the destination completely
in a real time with the same order as sending without corruption. The reliable
communication between physical things can be built in the transmission control
protocol (TCP) layers. In TCP layer, the reliable communication is required the
error detection, correction and confirmation to exchange information among
smart devices. In this paper, the author represents a framework to deal with
reliability issues to enable the adoption of IoT devices. The results found the
improvement in reliability.

A Novel Traffic Rate Measurement Algorithm for Quality of Experience-Aware Video Admission Control
Authors: Kist Alexander A. , qadir qahhar muhammad , ZHANG ZHONGWEI
Published: August 2020

With the inevitable dominance of video traffic on the Internet, providing perceptually good video quality is becoming a challenging task. This is partly due to the bursty nature of video traffic, changing network conditions and limitations of network transport protocols. This growth of video traffic has made Quality of Experience (QoE) of the end user the focus of the research community. In contrast, Internet service providers are concerned about maximizing revenue by accepting as many sessions as possible, as long as customers remain satisfied. However, there is still no entirely satisfactory admission algorithm for flows with variable rate. The trade-off between the number of sessions and perceived QoE can be optimized by exploiting the bursty nature of video traffic. This paper proposes a novel algorithm to determine the upper limit of the aggregate video rate that can exceed the available bandwidth without degrading the QoE of accepted video sessions. A parameter $\beta$ that defines the exceedable limit is defined. The proposed algorithm results in accepting more sessions without compromising the QoE of on-going video sessions. Thus it contributes to the optimization of the QoE-Session trade-off in support of the expected growth of video traffic on the Internet.
ADAPTIVE CAPACITY OF STUD RAMS OF ASKANIAN MEAT AND WOOL BREED AND PARAMETERS OF SELECTION OF ZAKARPATTJA-TYPE PRECOCE BREED EWES FOR INTER-BREEDING

Published: August 2020

The rams of the Askanian meat-wool breed, grown and kept in the conditions of the steppe zone of the south of Ukraine, were investigated for their adaptive capacity and adaptation to the conditions of the lowland regions of Zakarpattja.

It was found that the physiological response of the rams to the maximum air temperature was characterized by a slight increase in body temperature and pulse, and a significant increase in respiratory rate per 1 minute. The good adaptive properties of the Askanian meat and wool breed rams are indicated by the high breeding capacity of ewes, at 97%, in both farms. The ewes of the breed prekos with a live weight of 55.9–58.9 kg were involved in the breeding process, and the Askanian rams with a live weight of 93.3–95.1 kg. It was studied the influence of crossbred crossing of crossbred Askanian sheep of meat and wool breed on the development of productive and reproductive features of Zakarpattja sheep ewes of the breed prekos with the purpose of obtaining mixed breeds with improved economic performance. It is proven by theory and practice that one of the main criteria for the rational management of sheep breeding in modern conditions is the study of individual features of growth and development of young sheep. In a market economy, increasing the meat productivity of sheep is an important factor that determines the level of economic efficiency of the industry. Obtained progeny at the age of 4–8 months had a higher intensity of growth. Thus, the average daily weight gain of lambs in the control group was 234 g, and experimental — 265 g, which is 11.3% more than in the control. The average daily weight gain of the bright control group was 205 g, and the experimental one — 244 g, which is 11.9% more than in the control group. At the age of 8 months, the fat mass of slaughtered animals ranged from 32–36 kg and the carcass weight was 15–18 kg with good fat irrigation.

The classification of sheep carcasses by fat irrigation according to the EUROP system corresponded to the average level of coverage of carcasses with fat, that is, the whole carcass was covered with a thin layer of fat, at the base of the tail — small accumulations of fat, the kidneys partially or completely covered with a thin layer of fat, with a slight fatty water between visible intercostal muscles .The balanced feeding of experimental animals had a positive effect on the increase in live birth weight and their viability. The minimum selection parameters of breeding sheep ewes, which are involved in the breeding process, are also set for obtaining animals with high multi-farrowing and combined productivity.

Published: August 2020

The article presents the results of the study of «Indez» disinfectant. An effective disinfectant for use in animal husbandry should be easy to use, be non-toxic, have broad bactericidal spectrum, be non-carcinogenic, have non-addictive micro-flora and provide a permanent bactericidal effect in the presence of animals, while sanitizing the air environment. «Indez» disinfectant is a small, amorphous grey powder with a specific odour, well sprayed. It is composed of triiodomethane (iodoform), zinc oxide, iron sulphate (II) (iron sulphate), copper sulphate, silicon dioxide, zeolite, active essential oils, a complex of surfactants and pH regulators, auxiliaries. This preparation can be used in the presence of animals; the disinfectant effect is based on the spectrum of antimicrobial action of its constituents.

In the experiment of the study of the cumulative properties of «Indez» 80 white rats weighing 180-200 ± 10 g, tested doses of 1/5, 1/10, 1/20, from DL50 were used. To the animals of the experimental group, the suspension of the preparation was administered orally: in the first 4 days - 1/5 of DL50, then 1/10 and 1/20. Animals of the control group were administered saline at a dose of 0.5 ml. Observations on rats were carried out for 22 days. Depending on the dose of the drug, the cumulation coefficient.

As a result of the study of the cumulative properties of the drug it is established that the introduction of a total dose of «Indez» 56,8 cm3 per 1 kg body weight does not cause death of white rats. When conducting a total dose of 63,4 cm3 / kg body weight one animal died, representing 5 %. Further administration of the drug lethality was on the 18-th day (total dose 83,13 cm3 / kg) – 15 %, on the 19-th day (total dose 93,0 cm3 / kg) – 20 % and the 20-th day (total dose 102,87 cm3 / kg) – 45 %. With an increase of 9,873 1,5 times (1,8095 cm3 / kg) on the 21-st day, the mortality rate was 80 %, and on the 22-nd day of the studies 90 % of laboratory animals were killed, the total dose was 1032,49 cm3 / kg.

Under the study of the cumulative properties of «Indez» disinfectant, it was found that the cumulation coefficient in rats is 2,2 units. This, in turn, indicates that the test agent has moderately pronounced properties for cumulation. In this case, white rats inhibit the hematopoietic function of the bone marrow and reduce the body’s defences, as evidenced by a probable decrease in leukocyte count and a slight decrease in haemoglobin, lymphocyte count, spleen mass factor, and increased segmentation.
THE STUDY OF PATHOGENIC PROPERTIES OF ENTEROCOCCI ISOLATED FROM THE CARPATHIAN CHEESE
Authors: Kushnir I. I.
Published: August 2020

The article present the results of the studies pathogenic properties of enterococci isolated from the Carpathian brynza. Due to the high enzymatic activity enterococci give food unique taste properties. However, scientists have an ambiguous attitude to them, primarily due to the acquisition of resistance to antimicrobials by these microorganisms, and the ability of certain species to cause various diseases in humans and animals.

In the determining of infectivity was found that the intra-gastric administration of live enterococci at a dose of 108 CFU per animal, and in the study of toxicity - inactivated microorganisms, white mice remained alive. During the 14-day of observation period, the laboratory animals were active, had a satisfactory appetite, and maintained reflex excitability for sound and light stimulus. Therefore, the studied strains of enterococci E. durans SB6, E. faecium SB 12, E. durans SB18, E. durans SB20 are not infectious and non-toxic, as they did not cause any clinical symptoms and abnormalities in the overall condition of white mice.

The tested strains of enterococci don’t have enzymes which are related to the factors of pathogenicity, in particular, they did not have the catalase activity, which have pathogenic aerobic and facultative anaerobic microorganisms, did not produce lecithinase, which causes the de-polymerization of cell membranes of the microorganisms. In addition, the tested microorganisms did not produce plasma-coagulase and fibrinolysin that indicate on the apatogenic properties of the studied microorganisms.

The tested strains of enterococci did not cause an irritating effect on the mucous membrane of the eye. In the determination of acute toxicity, it was found out that intra-gastric administration of the tested strains did not cause signs of acute poisoning, death and diseases of laboratory animals. At the same time, during the 14-day of observation period, no changes in the clinical condition were detected in the animals.

In long-term use of enterococci, for 28 days, no changes in the clinical condition of laboratory animals were detected, but observed an increase in body weight of the animals. In particular, on the 28th day of the experiment was noted an increase in body weight of the animals which were administered strains of E. durans SB6, E. faecium SB 12, E. durans SB18, E. durans SB20, respectively, on 7.7, 7.5, 7, 32 and 10.2 %, compared to the values of animals of the control group.
OPTIMIZATION OF LIQUID CHROMATOGRAPHIC CONDITIONS TO SEPARATE WATER-SOLUBLE VITAMINS
Authors: Ostapiv R. D. , Tkachenko V. І.
Published: August 2020

Vitamins are widely used in veterinary medicine, in particular, as components of premixes, feeds and feed additives to increase the productivity of farm animals. Most of these feed additives are a complex amino acid and vitamin mixtures (of ten active substances or more) based on the matrix of plant or animal origin, which can be enriched with protein. When the analyst is faced with the difficult task of analyzing such a mixture, it is usually necessary to use several variants of the HPLC method (high-performance liquid chromatography), which increases the time and cost of analysis of the premix or feed additive. The aim of this work was to optimize the validated method of analysis of riboflavin in premixes and feed additives available in the laboratory for simultaneous (during one chromatographic separation) determination of the content of the maximum amount of water-soluble vitamins. A Waters liquid chromatograph equipped with an Alliance 2690 separation module with a PAD 996 diode array detector was used for separation. Water-soluble vitamins were separated on a Luna Omega Polar C18 250 × 4.6 mm, 5 μm chromatographic column. As solvents were used 0.05 M phosphate buffer pH 3.0 and 0.1 M sodium hydroxide solution (for folic acid).

The article describes the stages of liquid chromatographic separation parameters optimization of twelve vitamins and vitamin-like substances (thiamine hydrochloride, riboflavin, flavin mononucleotide phosphate, nicotinic acid, nicotinamide, calcuim pantothenate, phosidinobacino acidorinolobin, hydrocyanide). Chromatograms of standard samples solutions are given, which show the specificity of the technique. Isocratic and gradient elution schemes are investigated. Some parameters of chromatographic peaks under conditions of gradient separation of vitamins are estimated. The parameters of the chromatographic peaks do not exceed the limits recommended in the State Pharmacopoeia of Ukraine (SPU 2.0), that will allow to further carry out a more complete validation of the method for quantitative determination of water-soluble vitamins in various complex matrices: injection and oral solutions, feeds and premixes.

The article presents a literature review on the need to balance feed on L-arginine content, its characteristics, ways to supplement the diet of animals and poultry, as well as modern methods for quantitative determination of L-arginine in food, pharmaceuticals, etc. In the section «Materials and methods» the characteristic of the developed test technique, parameters of carrying out research, calibration characteristics with application of a standard sample of L-arginine and carrying out tests of amino acid content in a feed additive by means of system of capillary electrophoresis «Kapel-105M» are given. A description of the validation characteristics performed in the process of validation of the method is given. As a result of the conducted researches the technique of definition of the content of L-arginine in feed additives by means of a method of capillary electrophoresis is developed. The test procedure is based on the dissolution of the feed additive sample, further separation and quantification of the free form of L-arginine, its identification by individual absorption at a wavelength of 200 nm, temperature in the working capillary 30 ºC, voltage 25 kV and conductive electrolyte. The results of validation of this technique by the following characteristics are presented: repeatability, reproducibility, trueness, linearity, limit of quantification, budget uncertainty. The values of trueness, repeatability, reproducibility and uncertainty of the method (with a confidence level of (P) 0.95) does not exceed 5.0 %, the hypothesis of Linearity is acceptable, calculated on the basis of standard deviation (SD) limit of quantification for determining the content of arginine are satisfactory. The results allow us to conclude that the method of capillary electrophoresis using the device «Kapel-105M» is quite accurate and reliable in the case of studies of feed additives L-arginine with a content of the main substance of at least 98,0 %.
CONCEPT «MARKET» IN ECONOMIC THEORY
Authors: Temnenko S. M.
Published: August 2020

The essence of the market as an economic category was analyzed in the article. Interpretation of the "market" concept by the classics of economic thought as well as by modern domestic and foreign scientists was considered. The evolution of scientific knowledge regarding the depth of understanding and difference of approaches to the interpretation of this economic category was traced.

The market as an economic phenomenon has emerged as a result of such socio-economic processes as production and exchange. In the process of forming economically independent business entities, there was a transition from direct commodity exchange to more complex economic relations, such as buying and selling. The relationship between sellers and buyers gradually became more complex and multilevel. The concepts of supply and demand appear in economic theory, emerges a basic tenet of economics about the market as the main mechanism for establishing optimal proportions between production and consumption.

Thus, over time, the understanding of the "market" has transformed from a narrow interpretation as a platform where purchase and sale takes place to a complex mechanism that regulates economic relations in the process of production and distribution of resources and public goods.

An analysis of modern publications has shown that modern discourse on the nature of the "market" significantly expands the semantics of this concept. In our opinion, the thesis about the "market" - as a sphere of realization of human freedom, and about the person - as central and most important subject of market, is extremely interesting. In this regard, the age-old controversy of economists over the freedom of the market and the expediency of state intervention in the relationship between sellers and buyers, producers and consumers is gaining new arguments.

Often, modern market definitions are rather cumbersome and difficult to understand, therefore we offer a more concise definition of the market as an economic environment, which serves as a coordinating mechanism where producers, sellers and consumers interact in a competitive environment, and as a result of such interaction a general equilibrium of prices is formed.

Among the various forms of malware, Botnet is the serious threat which occurs commonly in today’s cyber attacks and cyber crimes. Botnet are designed to perform predefined functions in an automated fashion, where these malicious activities ranges from online searching of data, accessing lists, moving files sharing channel information to DDoS attacks against critical targets, phishing, click fraud etc. Existence of command and control(C&C) infrastructure makes the functioning of Botnet unique; in turn throws challenges in the mitigation of Botnet attacks. Hence Botnet detection has been an interesting research topic related to cyber-threat and cyber-crime prevention in network security. Various types of techniques and approaches have been proposed for detection, mitigation and preventation to Botnet attack. Here I discusses in detail about Botnet and related research including Botnet evolution, life-cycle, command and control models, communication protocols, Botnet detection, and Botnet mitigation mechanism etc. Also an overview of research on Botnets which describe the possible attacks performed by various types of Botnet communication technologies in future.

STOCK MARKET REACTIONS TO MERGERS ANNOUNCEMENT: AN EMPIRICAL STUDY ON RECENT 2020’S INDIAN MEGA BANK MERGER
Authors: Rajashree Upadhyay  , Dr. Mahesh Kumar Kurmi
Published: August 2020

Mergers and acquisitions are being used as strategic tools by Indian Corporate houses especially by Indian banking sector during last three decades of post liberalization era. Banking Sector in India has witnessed a mega merger of 10 Indian public banks into four big banks with effect from 1st April 2020 which definitely attract attention of different stakeholder who are interested to know whether these tie up events are really helpful for improving present scenario of banking industry as well as economic condition of the country in long run. But our concern in this study is to figure out the changes that occurred in shareholders wealth of the acquiring firm in short run around the announcement of merger event by detecting the responses of the share prices of acquiring bank through the procedure of event study methodology. For this study, company specific and market specific secondary data have been collected from the official website of National Stock Exchange as these companies are actively traded on said exchange. To accomplish the objective of this study we relied on figure of Average Abnormal Returns (AAR) and Cumulative Average Abnormal Returns (CAAR) for an event window of 41 days from day -20 to day +20. Return values have been statistically tested through cross sectional t-test. The notable finding of the research is that an under-reaction of market is observed before the announcement but the moment the announcement information becomes effective, investors start reacting from day +2 and the stock price jumps up, providing positive AARs to the investors. But after the positive respond to the merger information, finally investors have under-reacted to the event. CAARs figures also indicate the positive pattern of returns in the beginning of the event window but rapidly it becomes negative from day -16 to the last day of window that might be due to pandemic situation running throughout the world.

The use of chemical fertilizers with high doses and continuously in soybean cultivation can have a negative impact. Efforts to increase soybean production in an environmentally friendly manner need to be done, including using organic fertilizers and biological fertilizers. This study aims to determine the effect of doses of cow manure and kinds of biological fertilizers on the growth of soybean varieties Devon I. The research was conducted in Teguhan Village, Karangmalang District, Sragen Regency, altitude 86 m asl, with soil type Grumosol (PPT Vertisol). This study used a completely randomized block design (RAKL) with two treatment factors, namely the first factor the dose of cow manure consisted of 3 levels, namely P0 = 0 tons/ha, P1 = 10 tons / ha, P2 = 20 tons / ha, and kinds of fertilizers. Biological consists of 4 levels, namely H0 = without biological fertilizers, H1 = Trichoderma, H2 = mycorrhizae, H3 = Trichoderma and mycorrhizae. This study did not use inorganic fertilizers. The results showed that the dose of cow manure had a significant effect on soybean growth, but the type of biological fertilizer and the interaction between the dose of cow manure and the type of biological fertilizer had no significant effect on soybean growth. From the growth achieved, the use of cow manure accompanied by biofertilizer Trichoderma and mycorrhizae has the potential to increase soybean yields.
