Liberalizzazione, concentrazione e diversificazione del sistema bancario italiano
Authors: Baglioni Angelo
Published: July 2021

- Starting from the early nineties, the Italian banking system has undergone a deep process of deregulation, consolidation and diversification. The deregulation process has enabled Italian banks to enter new - geographical and product - markets. The single European market has introduced a competitive challenge from abroad. The concentration process may be explained on several grounds. Smaller banks have aimed at reaching a more efficient scale of production. Deals involving banks located in Northern and Southern Italy had a prudential rationale, given the weakness of Southern banks. Large banks have presumably pursued a defensive strategy, due to the threat of take-overs from abroad. An important role has been played by the moral suasion exerted by the Bank of Italy. Deregulation and consolidation have come along together with an increase of the competitive pressure, as shown by the decline of interest rate margins. Banks have reacted by diversifying their business, in order to expand their sources of revenue and to create switching costs for their customers (by selling bundles of services).

Innovazione e commercializzazione nei settori tradizionali: alcuni spunti di politica industriale
Authors: Tarola Ornella , Trento Sandro
Published: July 2021

- In an environment with increasing competition, the importance of taking care of customers through marketing, high quality service and after sale support has been shown to be crucial for getting competitive advantage. In spite of the clear evidence that technical innovations are not, by themselves, a guarantee of business success, a high number of firms in Italy seem not to pay attention to those factors affecting the level of perceived quality and still invest only in technical change and new equipment. In this paper, taking into account the Swedish experience in terms of industrial policy, we develop an analytical framework useful for a policy toward marketing innovation.

Les poles de compétitivité ou le retour ambigu des déclinaisons locales de la politique industrielle française
Authors: Plunket Anne , Torre André
Published: July 2021

- The French experiment of the "Pôles de compétitivité" is an original initiative of the French authorities in order to promote innovation-oriented collaborations and synergies between large firms, small companies and public research centres at the regional level. As such, it represents a striking revival of industrial policy and governmentguided programs towards supporting regional projects in terms of economic development. Launched in 2005, this policy is still pursued successfully, despite some ambiguities, in particular those concerning the large geographic dispersion of the projects supported and the financial support concentrated on a few very large clusters.

Paccheti anti-crisi nei paesi dell'Unione europea e il caso italiano
Authors: Ninni Augusto
Published: July 2021

- The article discusses the role of fiscal policies acting on the supply side within the recent economic stimulus packages of the EU countries, detailed according to OECD methodology and data. The supply side feature is analyzed according to the goals of the "new European industrial policy". Economic stimulus packages differ rather largely among countries in terms of size. Worthwhile features are: a) the supply side involvement often accounts for less than half of the whole package, the majority being focalized on the defence of income and purchasing power of the weaker population; b) a preference towards specific sectors occurs only for the automotive (of course in the car producing countries) and construction industries; c) a long term perspective (related to innovation, energy and environment) seems to be present only in few countries; d) concern about dangers from a new protectionism pushed by the State subsidies seems overstated. The Italian package is rather small: its size is justified by the high Italian debt/GDP ratio, but it cannot be explained according to perspectives on expected performance.

La regolazione nel settore elettrico: complessitŕ crescente, a vantaggio di chi?
Authors: Solimene Laura
Published: July 2021

- After a short description of the evolution of incentive regulation, this paper explores some of the issues arisen with its implementation in the electricity sector both in the UK and Italy. It points out the challenge for a regulator to implement an incentive mechanism under imperfect information, and focuses on some distortions emerged as a result of the design of the incentive scheme itself.
Struttura competitiva dopo la crisi Alitalia: il caso dela tratta Milano-Roma
Authors: Campopiano Giovanna , Kotlar Josip , Salanti Andrea
Published: July 2021

Air travel routes and high speed rail connection between Milan and Rome after the Alitalia crisis This paper analyses the first available data about changes in passenger traffic and air/rail fares after the Alitalia crisis and the substantial reduction of the travel time between Milan and Rome, due to the improvement of high speed rail on this connection. As recently happened in similar cases within Europe, the rail has gained a significant share of traffic previously attracted by air transport services. Apart from that, a real price competition is prevented by a number of inefficiencies which are mainly due to the monopolistic position of the new Alitalia on the route Milan Linate-Rome Fiumicino and problems of accessibility affecting our airports, and partly our rail stations too. The role of the various authorities potentially involved is burdened, in the last instance, by infrastructural deficiencies.
Incentive-based and knowledge-based theories of the firm: some recent developments
Authors: Meccheri Nicola , Morroni Mario
Published: July 2021

The article presents a critical review of the advances made in incentive-based and knowledge-based theories of the firm. In particular, the authors explore some developments in the incentive-based approach regarding relational contracts and contracts as "reference points", while the evolution of knowledge-based theories has led us to focus on the interesting implications of the concept of dynamic capabilities. Finally, we investigate some recent attempts to bridge these two main research streams, which have long been considered to clash with rather than complement each other.
Technological complexity and the evolving structure of MNC subsidiary knowledge accumulation
Authors: Cantwell John , Zhang Feng
Published: July 2021

The paper analyses the implications of increasing technological complexity and organizational restructuring for the knowledge accumulation activities of the subsidiaries of multinational corporations (MNCs). An analysis of foreign-owned subsidiaries in the German pharmaceutical industry in 1975-1995 indicates that the restructuring and intensification of knowledge exchange mechanisms in MNCs are an essential factor to enable subsidiaries to play a more creative role in knowledge generation. Although subsidiaries might use internal and external knowledge networks in their knowledge accumulation process in a complementary way, the purposes differ. In particular, the international internal knowledge networks of subsidiaries have been used increasingly for incremental knowledge building within the same field, whereas local external knowledge networks have been used far more for transferring more technologically complex knowledge.
Access to finance for innovation: the role of venture capital and the stock market
Authors: Bogliacino Francesco , Lucchese Matteo
Published: July 2021

Financial constraints for young and small firms can prevent them from contributing to innovation and the creation of new jobs. The paper analyzes two of the several institutional mechanisms implemented to overcome that hurdle: the development of the venture capital market and access to the stock market. The analysis is based on the information provided by two of the scoreboards used to monitor innovative activity in Europe: the IUS (Innovation Union Scoreboard) and the R&D Scoreboard. The former was used to study the determinants of venture capital/GDP intensity in Europe. The second was used to try to assess the stock market's contribution to R&D investment. The results show that, in the first case, the venture capital market complements structural features such as R&D intensity and market capitalization, is more volatile, and seems uninfluenced by competition-adverse regulations; in the second case, the analysis indicated that unlisted SMEs are more research intensive.
La produzione della natura nella postcolonia: la foresta Mau (Kenya)
Authors: Albertazzi Stefania , Bini Valerio
Published: July 2021

Muovendosi nell'ambito dell'ecologia politica e adottando la prospettiva teorica della produzione sociale della natura, questo contributo vuole illustrare come elementi umani e non umani coevolvono, determinandosi reciprocamente, nello specifico contesto della postcolonia. Si utilizzerà il caso studio della foresta Mau (Kenya), per mettere in luce l'esistenza di quattro socio-ecologie che si fondano sulle relazioni intrattenute con la foresta e la producono, a livello simbolico e materiale. L'analisi della "natura sociale" porterà a riflettere sulle temporalità complesse della condizione postcoloniale nella quale le diverse socio-ecologie non si esauriscono in un circoscritto periodo storico, ma continuano a disegnare le intricate geografie della regione.
La natura e l' immaginario: le aree protette come costruzioni sociali
Authors: Zanolin Giacomo
Published: July 2021

L'articolo propone alcune riflessioni sul significato delle aree protette nella prospettiva teorica della social nature. A partire dall'idea che la natura non ha valore in sé, ma è un costrutto culturale, viene qui presentata una discussione teorica basata su tre temi chiave, che offrono l'occasione per riflettere sul potenziale ruolo delle aree protette come elementi di una realtà costruita socialmente e come strumenti funzionali alla territorializzazione contemporanea. Le finalità teoriche sono perseguite attraverso l'analisi sintetica di un caso di studio: il Sistema Parchi dell'Oltrepò Mantovano. Il progetto innovativo che hagenerato questa esperienza singolare e il peculiare approccio alla preservazione e alla promozionedel patrimonio che la contraddistinguono, offrono pertanto spunti di riflessione utili a sostenere e rafforzare l'idea che le aree protette possono assumere un ruolo chiave nella costruzione e nella promozione di una visione alternativa di ciò che è naturale, contribuendo alla produzione di un immaginario collettivo fondato sull'ibridazione tra società e natura.
La video microanalisi nella terapia della coppia madre-bambino
Authors: Downing George
Published: July 2021

In occasione di un "incontro/confronto" organizzato dalla SIPRe a Milano il 21 febbraio 2009, George Downing ha illustrato il trattamento tramite video microanalisi di una coppia madre-bambina ricoverata nella clinica universitaria di Heidelberg. La madre, una donna abusata e gravemente traumatizzata durante la propria infanzia, rivela all'AAI di non avere elaborato la perdita traumatica di alcune importanti figure di riferimento e di andare incontro a fenomeni di micro dissociazione quando vengono evocate nel discorso. Nel video dell'interazione madre-figlia si notano con particolare rilievo la disfunzionalitŕ del comportamento materno e le strategie di adattamento della figlia. Messa di fronte a questa evidenza, la madre comprende meglio le ragioni della difficile intesa fra loro e ha la sensazione di "aprire una specie di porta".
Pensiero onirico e teoria del campo
Authors: Ferro Antonino
Published: July 2021

L'Autore, attraverso delle vignette cliniche, descrive i punti chiave del proprio modello clinico e traccia il suo modello di mente: "thinking-feeling-dreaming". Il concetto di campo analitico, come vero e proprio luogo d'incontro emotivo e di trasformazione psichica, cosě come il pensiero onirico della veglia, si collocano al centro del lavoro analitico. Secondo l'Autore, il campo accoglie e genera quelle turbolenze protoemotive che le funzioni alfa del campo alfabetizzano di continuo; il lavoro del campo consente poi lo sviluppo degli apparati per sognare, sentire e pensare. In questa prospettiva, una narrazione clinica con un alto grado di insaturitŕ risulta essenziale per favorire il moltiplicarsi dei punti di vista, cosicché il campo analitico possa diventare matrice di storie possibili. In questo modo l'"impensabile" diventa una storia condivisa, attraverso una serie di passaggi emotivi che permettono di nominare ciň che il paziente non ha potuto fin lě rappresentare.
Valutare la psicopatologia grave nell'adolescenza: alcune ipotesi sul trauma e la dissociazione per la comprensione dell'organizzazione borderline
Authors: Albasi Cesare
Published: July 2021

L'articolo riflette sulla salute e sulla psicopatologia nell'adolescenza in una prospettiva evolutiva che si nutre dell'orientamento relazionale in psicoanalisi, della teoria dell'attaccamento, dell'infant research. La salute č intesa con riferimento alla soggettivitŕ personale dell'adolescente e quindi come possibilitŕ di fare esperienza della propria esistenza come occasione di realizzazione di potenzialitŕ specifiche che lo contraddistinguono come individuo in crescita. Caratteristiche della salute sono la capacitŕ di integrazione mentale, la flessibilitŕ delle funzioni mentali e dell'organizzazione della personalitŕ, la possibilitŕ di elaborare i conflitti (intrapsichici ma intesi in senso relazionale e non pulsionale) con capacitŕ che si vanno strutturando come sostegno allo sviluppo, la resilienza necessaria per fronteggiare le esperienze potenzialmente traumatiche, perché disconoscenti le proprie necessitŕ evolutive specifiche, senza strutturare processi dissociativi pervasivi. La psicopatologia č concepita in modo strettamente connesso alla diagnostica, con riferimento al PDM, e discussa con riferimento ai livelli di organizzazione: particolare attenzione č posta sul livello organizzazione borderline e sui processi dissociativi sul loro ruolo nell'organizzare i livelli borderline di organizzazione della personalitŕ.
L'adolescente di fronte al suicidio: morte e creativitŕ di Narciso
Authors: Pietropolli Charmet Gustavo
Published: July 2021

Viene indagata, sulla base di una estesa attivitŕ clinica con adolescenti reduci da tentativi di suicidio, la relazione intercorrente fra la fragilitŕ narcisistica e le crudeli esperienze di depressione narcisistica che tale condizione promuove e la rappresentazione della morte. Decolla in questi casi una energica spinta creativa che regala alla morte un valore estetico elevato e la connota come soluzione di gran lunga piů valorizzante della vita. Il Sé suicidale vive ed opera in uno spazio chiuso del Sé privo di qualsiasi azione relazionale, ma quando si incontra con il terapeuta puň dare vita ad un nuovo Sé non suicidale, memore della relazione con la morte ma deciso a differirne l'avvento.
Il lavoro dell'adolescenza e il lavoro con l'adolescente
Authors: Pellizzari Giuseppe
Published: July 2021

Il concetto di "lavoro" č implicito in tutta l'opera di Freud. Designa una attivitŕ di mediazione e di lotta con un oggetto, interno e/o esterno, che ostacola il soggetto imponendo una trasformazione. Il modello naturale di tale lavoro č l'adolescenza come processo di riorganizzazione psichica rivoluzionaria che implica uno sforzo creativo considerevole per ridefinire l'identitŕ del soggetto. La societŕ in cui viviamo tende a banalizzare questo compito favorendo la scarica eccitatoria immediata a scapito della creativitŕ che comporta il tempo. Il lavoro terapeutico con gli adolescenti consiste nel riattivare la drammaticitŕ della loro crisi piuttosto che reprimerla in modo rassicurante. Ciň implica la fiducia nelle nascenti capacitŕ creative dell'adolescente e nello stesso tempo la sospensione del proprio "supposto sapere" al fine di riconquistarlo insieme nella costruzione di un comune spazio di lavoro. Due esempi clinici esemplificano questo processo.
Tu sei me e io sono te
Authors: Minolli Michele
Published: July 2021

Alla visione teorica individualistica e intrapsichica che storicamente ha strutturato l'intervento sulla coppia, viene contrapposta una presentazione della coppia come

. Nella coppia, cioč, l'interazione con cui l'Io-soggetto diventa se stesso attraverso l'altro č retta, facilitata e favorita dall'amore. Viene poi presentata la legge della funzionalitŕ, che non ha niente a che vedere con proiezione o introiezione o identificazione proiettiva. La funzionalitŕ non č solo una chiave di lettura per tutti i rapporti, ma illumina e determina anche il costituirsi dell'innamoramento, la vita assieme di ogni giorno e le crisi inevitabili che accompagnano l'evolvere della coppia. Alcuni esempi clinici, tratti dall'esperienza dell'intervento psicoanalitico di coppia, accompagnano l'esposizione teorica. La coppia, da sola o con l'aiuto, quando č necessario, dell'intervento psicoanalitico, č uno strumento di crescita dell'Io-soggetto: "Io sono te e tu sei me".
Il ruolo degli affetti nella vita psichica, nel lavoro diagnostico e in quello terapeutico. Le personalità "come se"
Authors: Loiacono Anna Maria
Published: July 2021

Il concetto di personalità "come se" si rivela profondamente attuale. Sottratto alla psicopatologia, nella quale Helen Deutsch lo sviluppa, esso viene trasportato nell'ambito della "normalità" da Paul Roazen, che analizza i processi imitativi, non già identificatori, di legame con il leader. Ne emerge la visione di un generale conformismo che non risparmia neppure gli esponenti della nostra professione. Nel lavoro terapeutico, il fenomeno sociale delle personalità "come se" appare evidente attraverso il "terapeuticismo" cui si viene spesso allenati sin dalla formazione, ovvero attraverso l'attenzione prevalente verso le classificazioni e il risultato terapeutico. In sostanza, un tale conformismo psicoanalitico può essere visto come il "come se" collettivo del nostro mestiere, dove, nonostante i numerosi richiami all'autenticità, si sciorinano ricette su ciò che si "deve" fare. Una esemplificazione clinica tenta di mostrare la peculiarità del concetto e le difficoltà che si possono incontrare nel diagnosticarla.
L'apprendimento come danza relazionale
Authors: Vanessa Bozuffi , Gian Luca Barbieri
Published: July 2021

Gli Autori, definendo la comunitŕ scolastica come il contesto elettivo di apprendimento, evidenziano quanto proprio attraverso essa si possa giungere ad una reale integrazione sociale degli studenti ad opera dei loro partner di ruolo. Gli Autori propongono una lettura dell'apprendimento in chiave bioniana, declinata anche secondo il modello meltzeriano, come crescita e sviluppo, quindi come cambiamento della persona nella sua totalitŕ, e dunque in modo radicalmente differente dall'apprendimento nozionistico. Considerando inoltre il contributo di Loewald riguardo alla mente, di Bion rispetto alla teoria del pensiero e alla sofferenza psichica poi rielaborato da Meltzer e l'ulteriore contributo di quest'ultimo rispetto alle funzioni emotive, gli A. giungono a considerare il processo di apprendimento come dato emergente dalla relazione. Č quindi attraverso le relazioni attivate nel contesto scolastico che č possibile l'apprendimento ed anche l'integrazione sociale se il docente č in grado di condurre la "danza relazionale" adottando la reverîe professionale.

Objective: To determine the diet of the desert bighorn sheep and to identify differencesin its composition between sexes during the reproductive and sexual segregation periods.Design/methodology/approach: The study was carried in the UMA Rancho NocheBuena, Hermosillo, Sonora. The microhistological technique and a cell catalog of plantsfrom the study area were used to identify plant species present in fecal samples ofbighorn sheep. The relative frequency, the Shannon-Weaver diversity index and theKulczynski similarity index were determined by sex and period (reproductive andsegregation)Results: The diet of bighorn sheep included 40 species, being herbaceous (36.1 ±4.4%) and grasses (26.8 ±8.9 %) the most common. The diet of males during thesegregation period was mainly composed of grasses (36.2%) and female diet byherbaceous (30%) and grasses (29.8%). No differences were found in the diversity ofthe diet of males and females in the segregation period (H '= 1.0) and in general, their diets were very similar (80%).Limitations/implications: To collect a greater number of fecal samples by sex andperiod (reproductive and segregation) and to analyze the nutritional content of plantsconsumed by bighorn sheep.Findings/conclusions: In this study, the sexual segregation exhibited by the bighornsheep in the Wildlife Management and Conservation Unit Rancho Noche Buena was notdue to food preferences.
Effectiveness of osteopathic care in the treatment of infant positional posterior plagiocephaly
Authors: Marangelli G. , Adouard Ju. , Josse B. , Ducourneau J. , Chastagner A.-S. , Messien C.
Published: July 2021

Introduction.Posterior Positional plagiocephaly (PPP) is a cranial deformation seen in infants. The case number increased since 1992, following the supine sleeping advice. Most of the time several factors are combining together, leading to a multi-level lack of mobility of the infant, thus leading to the cranial deformation. Studies show this deformation to be linked with perturbations in various fields.Objective.This study aims to assess the efficacy of osteopathic care on the severity of the PPP.Materials and methods.100 infants were recruited in an osteopathic practice in Lyon (France). All the infants followed the same study protocol; however, the treatment was individualized. Three consultations occurred with a 15 days′ interval over 30 days′ period. Craniometric measurements were realized with Mimos® craniometer on each consultation.Results.The mean severity of the PPP was 10,1 mm at Day 0. At day 30, this average was down to 6 mm. It is a significant (p<0,001) clinical and statistical decrease. Out of the 100 infants, 98 had a decreased deformation while two stagnated.Conclusions.As every infant is unique, every plagiocephaly is different, thus the treatment was not standardised. This study suggest some effectiveness for osteopathic care in the cranial asymmetry of infants with PPP. Other studies should be done, some with a control group, in order to compare our results with spontaneous evolution of plagiocaphaly.

Published: July 2021

In recent years, fuzzy rough set based attribute reduction has attracted the interest of many researchers. The attribute reduction methods can perform directly on the decision tables with numerical attribute value domain. In this paper, we propose a fuzzy distance based attribute reduction method on the decision table with numerical attribute value domain. Experiments on data sets show that the proposed method is more efficient than the ones based on Shannon’s entropy on the executed time and the classification accuracy of reduct.

Authors: Ojirobe Yunusa , Yahaya Abubakar , Abdulkarim Muhammad
Published: July 2021

A major cause for concern in hospitals is congestion, which brings about untoward hardship to patients due to long queues and delay in service delivery. This paper seeks to minimize the waiting time of patients by comparing the performance indicators of a single server and multi-server model at the Paediatrics Department of Muhammad Abdullahi Wase Specialist Hospital Kano (MAWSHK). In order to achieve this, primary data was obtained through direct observation which in turn is subjected to the test of goodness of fit to ascertain the distribution that best describes the data. The performance indicators comprising utilization factor, average number of patients in the queue, average number of patients in the system, average waiting time in queue and average waiting time in system for a single server and multi-server model were computed and analyzed respectively. Our findings indicate that the G/G/4 model performs better compared to the G/G/1 model as it minimizes the waiting time of patients

Modeling of credit portfolio management efficiency
Authors: Ostrovska N.
Published: July 2021

Credit operations, among the great variety of services provided by the bank, are one of the most important activities. In the assets of commercial banks, loans occupy a strong position of the most extensional and profitable items. The reliability and financial stability of commercial banks depends on the composition and structure of the bank's loan portfolio and the process of its management. Under current conditions, the development and improvement of the bank's loan portfolio management system intended to minimize the credit risks and ensure the sustainable operation of commercial banks have become particularly important. Crisis phenomena in economy have proved that the activities of any economic entity is associated with uncertainty in market development. Adverse developments in the world markets directly affected the solvency of borrowers of many banks. The increase in defaults of most borrowers resulted in the increase in defaults on loans, causing the increase in overdue debt, lower profitability and liquidity problems in banks. Thus, the recent crisis in the world economy, including Ukrainian economy, has demonstrated the failure of the methods used to assess and manage credit risk in banking, as well as the imperfection of the methods used to manage the loan portfolios of commercial banks. The results of the previous carried out investigation indicate that in order to form the correct management decisions and take practical actions concerning the formation of loan portfolio for commercial bank, it is necessary to assess its status. In this regard, the method of econometric modeling (determination of the relationship between gross domestic product and overdue debt of the banking system in Ukraine, the relationship between the volume of loans issued by banks and the discount rate; the relationship between the volume of loans issued to individuals and the volume of the loan portfolio in general) is differentiated in this paper from other estimation methods. This method made it possible to determine the effectiveness of loan portfolio management of commercial banks. The results of the calculations provide reasons to confirm that there is insignificant relationship between the level of loans to individuals and the loan portfolio.
Assessment of the protective effect of Artemisia herba-alba Asso against Eimeria tenella induced coccidiosis in broilers
Authors: Messaï A. , Redouane-Salah S.
Published: July 2021

Background: The present study was designed to investigate the protective effect of a natural product to control coccidiosis in broilers. We studied the effect of the dried leaves of Artemisia herba alba Asso supplement against artificially induced coccidiosis in broilers.
Methods: One hundred twenty chickens were allocated into four equal groups of thirty, negative control (UUG), positive control (IUG), Monensin-treated Group (MTG), and Artemisia-treated group (ATG). The infected chickens with E. tenella were treated with 100ppm of monensin and, 5% of Artemisia in the feed.
Results: No mortality was recorded in ATG animals. Oocysts excretion was significantly (p<0.05) reduced in ATG animals at the 6th and the 8th days post-infection. The highest reduction of oocysts shedding in faecal samples (79.04%) was in Artemisia-treated chickens. The effect of Artemisia was comparable to that of monensin.
Conclusion: Artemisia herba alba Asso is of particular interest in fighting coccidiosis since it has a preventive effect on mortality and reduction of oocysts faecal shedding during caecal coccidiosis.
Potential for application of feed additives encapsulation technology in animal nutrition
Authors: Kolar Sara , Jurić Slaven , Vlahoviček-Kahlina Kristina , Vinceković Marko
Published: July 2021

Demands for higher production and consumer demand for healthier food have encouraged intensive research for alternative animal growth promoters in recent years. Research trends are focused on the development of new products enriched with feed additives to improve animal health and enhancing production. Many of these compounds are unstable in the presence of light, air, water, or high temperatures and need to be protected during processing, storage, and application. By encapsulatied in microparticles, feed additives are protected from harmful external influences, and their stability and functionality are not diminished. Microencapsulation technology is used to protect payload and improve bioavailability by controlled and targeted delivery to the digestive tract. It is particularly suitable for the addition of feed additives in ruminant’s nutrition, because the correct choice of microparticle material allows the release of the feed additives in the small intestine, and not in the rumen. With proper use, microparticle formulations are an effective tool in animal nutrition that delivers nutrients and/or drugs to a specific site at the desired rate. The paper summarizes laboratory studies on the application of microencapsulation technology in feeding ruminants and monogastric animals. Numerous results of the application of encapsulated feed additives have shown a positive effect on animal health, increased productivity without negative effects on the final product, and environmental protection.

Published: July 2021

The objectives of this study are to study and test the effect of using the effect of the single leg and double leg bounding exercise program (BEP) on the improvement of physical agility, strength, balance, and leg muscle power. The subjects of this study were 42 students of Physical Education class 2017 STKIP PGRI Jombang.This type of research is quantitative with quasi-experimental techniques. Sampling using the Solvin formula and purposive sampling technique. The process of taking data from the initial test and the final test uses the leg dynamometer test to determine leg muscle strength, side step test for agility, force plate test for leg muscle power, and balance beam test for balance.The results of the study on the normality and homogeneous tests showed normal and homogeneous data results with a significance value above 0.05. The mean difference test was carried out using the paired test and the Manova test. The method of increasing the agility, strength, balance and leg muscle power has a significant improvement with the two experimental methods.The conclusion of this study is that the bounding exercise program can significantly increase the agility, strength, balance and leg muscle power. However, from the two exercises the increase was greater in the group using the single leg bounding type of exercise.
Bezier Polynomials with Applications
Authors: Islam Nazrul , Islam Md Shafiqul
Published: July 2021

In this paper, we use the Galerkin technique for solving higher order linear and nonlinear boundary value problems (BVPs). The well-known Bezier polynomials are exploited as basis functions in the technique. To use the Bezier polynomials, we need to satisfy the corresponding homogeneous form of the boundary conditions and modification is thus needed. A rigorous matrix formulation is developed by the Galerkin method for linear and nonlinear systems and solved it using Bezier polynomials. The approximate solutions are compared to the exact solutions through tabular form. All problems are computed using the software MATHEMATICA.

Structural and Electronic Properties of Adenine-Thymine Basepair : A Computational Study
Authors: Mohammad Alauddin - , Debnath Tapas , Aziz Mohammed A
Published: July 2021

It is well known that stability of deoxyribo-nucleic acid (DNA) double helix depends on hydrogen bonding (HB) between adenine-thymine and guanine-cytosine. HB plays an important role in molecular systems, particularly in biological systems because all lives on the earth may be viewed as a matter of hydrogen-bonding supramolecular systems. Since HBs have a central role on the mechanism of life phenomena including the structure and functions, it is essential to understand the molecular-level aspects of HB systems. Therefore, we studied the structural properties of adenine-thymine (A-T) basepair theoretically using DFT/B3LYP/6-31G level of theory. Theoretically we found four isomers of A-T basepair and the most stable isomer is one in which adenine and thymine are connected via two hydrogen bonding. The electronic properties were calculated by Time Dependent Density Functional Theory (TD-DFT) approach.

Published: July 2021

In this paper, a dual-conversion online static UPS and Line-Interactive UPS system was modeled and simulated using PSIM software. The components of the proposed design were specified based on pre-defined constrains, and the dynamic behavior of the system was modeled through state-space equations. With the system components characterized, a suitable controller was developed for closed-loop control of the buck and boost circuits. A battery charge management controller was also developed to ensure the robustness of the design. Overall system performance was analyzed under varying load and line conditions. Conversion bypass switching was simulated and the overall system performance was analyzed while observing the state of charge – SOC behavior of the battery.

Authors: Hossain ABM Shahadat , Noushin Maliha Tasmiah , Hasan Kamrul
Published: July 2021

In this paper we estimate European put option price by using awell-established option pricing model, namely, the Constant Elasticity of Variance (CEV) model for the elasticity parameter β< 2 and then compare it with the benchmark Black-Scholes (BS) model. We calculate the Greeks under the CEV model for β=0,1 and 1.95 and compare them with that of the B-S one. Finally, we investigate the put price and Greeks values for at-the-money (ATM), in-the-money (ITM) and out-of-the-money (OTM) situations.

Published: July 2021

The as-triazines containing iron(II) methine chromophoric group; 3-(2-pyridyl)-5,6-diphenyl-as-triazine (PDT), and 3-(2- pyridyl)-5,6-bis(p-methoxyphenyl)-as-triazine (PBMPT) have been prepared from commercially available relatively cheaper reagents. The absorptiometric characteristics of the iron(II) complexes with PDT and PBMPT have been re-evaluated. The interference of copper ion on the determination of iron with these selective reagents and its masking has also been studied. The application of these spectrophotometric reagents for determination of iron in water samples based on the formation of extractable PDT-iron(II) and PBMPT-iron(II) complexes in chloroform medium has been described. Standard addition technique was used to verify the reliability of the method. Repeated determinations gave results with a very small standard deviation.

Effect of Heat Generation and Thermal Radiation on the Slip Flow of Time Dependent Elastico-viscous Maxwell Nanofluid Flow Over a Porous Stretching Inclined Surface
Authors: Samad M Abdus , Karim M Enamul
Published: July 2021

The present paper deals with the numerical analysis of the combined effect of heat generation and thermal radiation on the flow of a time dependent elastico-viscous Maxwell nanofluid passing over a stretching porous inclined surface with slip boundary. Appropriate similarity transformations are used to decorate the governing equations into a set of ordinary non-linear differential equations. The coupled ordinary equations are solved numerically using the Nachtsheim-Swigert shooting method together with the Runge-Kutta iterative technique for various values of the flow control parameters. In addition, the built-in function bvp4c of MATLAB is used to enhance the consistency of numerical results. The numerical results, demonstrated graphically, are described from the physical point of view. Finally, the effects of relevant parameters on the local skin-friction coefficient, the local Nusselt number, and the local Sherwood number, which are of material concern, are demonstrated in tabular form.

Authors: Reza AKM Selim , Suraiya Sayma , Hasan M Babul
Published: July 2021

In this paper, we develop a mathematical model combining forecasting and linear programming for a business organization of Bangladesh to calculate optimum order quantity and inventory cost. We test the model using raw data of the demand for the raw materials and spare inventory for the industry and find out minimum total inventory cost along with ordering cost and inventory holding cost. The developed model make a match between the forecasted demand of raw materials and spare inventory and the minimum total cost of inventory. Finally comparing minimum cost, we observe that our estimated appropriate forecasting method gives optimal inventory cost.
