Pesatnya perkembangan teknologi khususnya teknologi informatika tak bisa ditolak keladiranya mereka yang menyelami perkembangannya tak bisa dilihat sebelalı mata saja. Di samping itu, sebaliknya mereka yang tidak meyelami atau tidak mengikuti perkembangannya, maka akan mundur secara sukarela dalam tahap kompetensi dunia, dikarenakan dunia saat ini sangatlah familiar dengan teknologi computer ini. Sekarang, orang - orang yang memiliki lingkungan yang luas dan disenangi, serta dapat dijadikan lading berbiisisnis atau menghasikan materi adalah dunia pemograman computer. Pada ruang lingkup pemograman computer terdapat ribuan macam tahasa pemograman yang disususn secara teratur oleh algori:ma. "Algoritma adalah urutan langkah-langkah logis untuk memecahkan masalah yang disusun secara sistematis dan logis". Makna dari kata logis yang tertera diatas yakni sebagai kata kunci dalam algoritma. Step-step dalam penyusunan algoritma kendaknya memiliki penalaran logika yang tepat dan dapat diterntukan kebenarannya baik itu bersifat benar maupun salah. Pada beberapa masukan algoritma berarti step-step yang rinci yang dibuat untuk melakukan perbuatan tertentu. Peninjauan pada penentuan suatu algoritma yaitu, algoritma yang akan disusun harus benar. Maksudnya, algoritma akan memberikan masukan dari banykanya masukan yang ditentukan yang telah ditentukan. Adapun jika, seseorang memberikan masukan yang salah maka algoritma tersebut pasti tidak benar atau salah pula. Masalah seperti ini harus diperhatikan secara matang oleh para pemula untuk menghasilkan algoritma yang baik dan benar, namun minimnya pengetahuan dasar ilmu komputer khususnya dibidang algoritma menjadi tantangan tersendiri bagi pemula untuk memulainya.

A kinetic and mechanistic investigation, using conventional UV-Vis spectrophotometry, of the reaction between dimethyl acetylenedicarboxylate (DMAD) and 1,3-dicarbonyl compounds including acetylacetone (ACAC) and dibenzoylmethane (DBM), has been conducted in a methanol environment with triphenylarsine (TPA) acting as a catalyst. Previously, in a similar reaction, triphenylphosphine (TPP) (instead of TPA) had been employed as a reactant (not a catalyst) for the generation of an ylide (final product). In the present work, of significance is the differential behaviour of TPA which, as a catalyst in the reaction environment, leads to a cyclopropane compound. Of other significance is the different behaviours of the two reactants in the kinetics and mechanism of the reaction. In previous work, TPP acted as a weak nucleophile (a reactant), so the first step of the reaction was recognised as the rate-determining step (RDS). Here, TPA reacts as a stronger nucleophile and a catalyst, resulting in the fourth step of the reaction (step4, k4, a proton transfer process) being recognised as the RDS. The reaction followed second-order kinetics. The proposed mechanism was adapted in accord with the experimental results and the steady-state assumption. The results showed that the reaction rate decreases in the presence of DBM, which participates in the second step (step2), compared to ACAC when it is present as another 1,3-dicarbonyl compound (structural effect). In addition, in previous work, the partial order of the reaction with respect to the 1,3-dicarbonyl compound was zero, while it is one in the present work. As a significant result, not only did a change in the structure of one of the reactants (TPA instead of TPP) create a different product, but also the kinetics and reaction mechanism changed. In addition, the reaction is enthalpy-controlled.

Expressive Dimension

Total Reduplication (henceforth TR) of the type exemplified by Modern Greek aspros aspros ‘white white’ “very white” and vima vima ‘step step’ “step by step” has an expressive dimension, mainly in that it is an optional strategy and it almost always has pragmatic connotations and effects (e.g. making a narration more vivid) (see, e.g., Zwicky & Pullum 1987; Beard & Volpe 2005). This paper poses the question whether TR can be viewed as a category of constructions that exclusively serve as expressive markers in Modern Greek (MG). I discuss the arguments and counterarguments to the idea that TR in MG can be described as a process of “expressive morphosyntax”, in parallel to Zwicky & Pullum’s (1987) notion of “expressive morphology” (which mainly refers to processes such as play languages, ideophones, and schm-reduplication). I also refer to a wide range of criteria of expressivity (involving functional as well as formal characteristics of expressives) in the relevant literature. The discussion points to an incomplete overlap between typical categories of expressives and TR. It also clarifies the senses in which TR is “expressive” and touches on issues of the status of TR in the grammar.

Exact solutions for the one-dimensional problem of a compressible fluid having a time-dependent pressure at the source (fracture face) and displacing a compressible reservoir fluid are generated. Special solutions for various cases represented by step, step with constant slope front, and sinusoidal pressure variations at the fracture face are derived. Numerical results and trends for fluid interface motion are revealed for selected cases. The applicability of the presented solutions to hydraulic fracturing is discussed. In addition, response solutions for problems in reservoir mechanics, underground coal gasification, and nuclear waste management can be similarly investigated.
