Infinite Matrices and Their Recent Applications

Infinite Matrices and Their Recent Applications

P.N. Shivakumar; K.C. Sivakumar; Yang Zhang

Springer International Publishing AG
2016
sidottu
This monograph covers the theory of finite and infinite matrices over the fields of real numbers, complex numbers and over quaternions. Emphasizing topics such as sections or truncations and their relationship to the linear operator theory on certain specific separable and sequence spaces, the authors explore techniques like conformal mapping, iterations and truncations that are used to derive precise estimates in some cases and explicit lower and upper bounds for solutions in the other cases.Most of the matrices considered in this monograph have typically special structures like being diagonally dominated or tridiagonal, possess certain sign distributions and are frequently nonsingular. Such matrices arise, for instance, from solution methods for elliptic partial differential equations. The authors focus on both theoretical and computational aspects concerning infinite linear algebraic equations, differential systems and infinite linear programming, among others. Additionally, the authors cover topics such as Bessel’s and Mathieu’s equations, viscous fluid flow in doubly connected regions, digital circuit dynamics and eigenvalues of the Laplacian.

Misclassification of Smoking Habits and Passive Smoking

Misclassification of Smoking Habits and Passive Smoking

P.N. Lee

Springer-Verlag Berlin and Heidelberg GmbH Co. K
1988
nidottu
How accurate are statements about smoking habits? This book presents the results of a comprehensive review in which the literature on the subject is newly interpreted. It is shown that smokers are misclassified as non-smokers in epidemiological studies often enough to explain the increased lung cancer risk seen in self-reported non-smokers in relation to their spouse's smoking habits. This study overturns the commonly held view that increased risk is a consequence of exposure to environmental tobacco smoke and highlights the difficulty of making valid inferences from epidemiological data. No-one should draw conclusions about passive smoking before reading this book!

Salbutamol Drug Delivery by Core in Cup Device

Salbutamol Drug Delivery by Core in Cup Device

P N Mallikarjun

Lap Lambert Academic Publishing
2024
pokkari
Core and cup tablet of Salbutamol sulphate for chronotherapeutic delivery was prepared to increase the effectiveness of drug by using optimization technique.The formulation contains three components a core tablet, impermeable layer and soluble hydrophilic polymer layer. The core tablet contains salbutamol sulphate drug and other excipients, impermeable layer is made up of Ethyl cellulose (EC), and the polymer layer is made of HPMC 15cps and HPMC 50cps. In this work the key ingredients like HPMC 15cps and HPMC 50cps were optimized by using 32 Factorial designing in this various proportions of HPMC 15cps and HPMC 50cps (polymers) were used in different levels in the preparation of core in cup tablet.

Clotrimazole is an imidazole derivative with a broad spectrum of anti-mycotic activity. The Present investigation is the design and characterization of Novel Emulgel of Clotrimazole. Nine different formulations of Emulgel were prepared by the proposed method of preparation by Mohammad et.al (2004), varying with different 2 different polymers of gelling agent such as Carbopol 934 and HPMC K15 M and their combinations in different ratios. All the Formulations were characterized for physical evaluation, drug content, Viscosity, spreadability, extrudability, and In-vitro Drug release studies. Stability studies were revealed with marginal differenceswith a good stability. Also this study refers to the kinetic data of the drug release studies.

Soderzhanie etoj knigi napominaet igru s ognjom. Po krajnej mere, s obyvatelskoj tochki zrenija eto, skoree vsego, budet vygljadet tak, potomu chto mnogoe iz togo, o chjom vy uznaete, prilichno vydeljaetsja na fone prinjatogo i samogo prostogo jazykovogo podkhoda k razdeleniju na "pravilnoe" i "nepravilnoe". Eta kniga ne dlja bortsov za chistotu jazyka i tem bolee ne dlja grammar-natsi. Potomu chto i te, i drugie tak ili inache podverzheny vspyshkam jazykovogo vysokomerija. Ja ubezhdena, chto ljubov k jazyku kroetsja ne v iskrennem zhelanii borotsja s oshibkami. Ljubov k jazyku kroetsja v prinjatii - mozhno sejat razumnoe, dobroe i vechnoe bezo vsjakikh otsenochnykh suzhdenij. Potomu chto vremja idjot, mir menjaetsja - i jazyk eto otrazhaet.Eto jarkoe tsvetnoe izdanie stanet otlichnym podarkom i budet interesno kak detjam, tak i vzroslym, zhelajuschim uznat o samykh neozhidannykh osobennostjakh nashego velikogo i moguchego russkogo jazyka.

Kogda v obychnoj zhizni delo kasaetsja jazyka, my chasto myslim stereotipami: "russkij jazyk mne eschjo v shkole ne davalsja", "vazhno govorit pravilno, no realnaja zhizn - eto ne shkolnyj urok" i tomu podobnoe.Davajte priznaemsja: sovremennyj temp zhizni ne pozvoljaet nam postojanno shtudirovat slovari i spravochniki, chtoby podderzhivat gramotnost na dolzhnom urovne. No chto esli ne vpadat v krajnosti, a prevratit etot protsess v uvlekatelnoe zanjatie, ne otryvajas ot povsednevnykh del? Eta kniga kak raz i pomozhet vam spravitsja s takoj zadachej. Ejo glavnaja osobennost - nestandartnaja podacha materiala, kotoraja nauchit vas byt bolee vnimatelnymi k sobstvennoj rechi, russkomu jazyku vokrug vas i dazhe pomozhet razvit jazykovuju intuitsiju.Eto novoe spetsialnoe izdanie s zadanijami dlja vsekh chitatelej populjarnogo v runete instagram-bloga "Velikij russkij" @great_russian, a takzhe bestsellerov Poliny Masalyginoj "Velikij russkij", "Moguchij russkij" i "Ljubimyj russkij", kotoroe mozhno ispolzovat kak planer na god
