Apartheid of South Africa in Gordimer’s July’s People

Nadine Gordimer’s July’s People (1981) foresees the inevitable collapse of White South Africa and the emergence of new political and social realities. In this novel the blacks in the South African police force refuse to arrest their own people, so public services were break down and riots occur in major cities, quickly spreading into the rural areas

Social Thoughts of the Poet Snehan

The definition of renewal poetry is different today, but renewal poetry is intended as a poetic tradition, a poetic system devoid of grammar. The genealogy is to be found with the restrictions of the syllable, the thigh, the foot, the thigh, and the renewal is seen with a new look as if it had been cast out. The scene seen in the novels is universally accepted as having a realistic lyricism and sense of humor with simple Tamil words as it is without rhetorical words, and female poets and males use simple words with low footnotes to point out their experiences and social disorders. In the poems of the poet Snehan, who is a guide for today's younger generation, this essay expresses his social thoughts on language, patriotism, the sanctity of women, the purity of friendship and many more from his point of view

Maintaining Acyclicity of Concurrent Graphs*

In this paper, we consider the problem of preserving acyclicity in a directed graph (for shared memory architecture) that is concurrently being updated by threads adding/deleting vertices and edges. To the best of our knowledge, no previous paper has presented a con- current graph data structure. We implement the concurrent directed graph data-structure as a concurrent adjacency list representation. We extend the lazy list implementation of concurrent linked lists for maintaining concurrent adjacency lists. There exists a number of graph applications which require the acyclic invariant in a directed graph. One such example is Serialization Graph Testing Algorithm used in databases and transactional memory. We present two concurrent algorithms for maintaining acyclicity in a concurrent graph: (i) Based on obstruction-free snapshots (ii) Using wait-free reachability. We compare the performance of these algorithms against the coarse-grained locking strategy, commonly used technique for allowing concurrent updates. We present the speedup obtained by these algorithms over sequential execution. As a future direction, we plan to extend this data structure for other progress conditions

An Area Efficient Pulse Triggered Flipflop Design under 90nm CMOS Technology

The choice of flip-flop technologies is an essential importance in design of VLSI integrated circuits for high speed and high performance CMOS circuits. The main objective of this project is to design an area efficient Low-Power Pulse- Triggered flip-flop. It is important to reduce the power dissipation in both clock distribution networks and flip-flops. The comparison of low power pulse triggered flip-flops such as Ep-DCO, MHLFF, ACFF, Ip-DCO, conditional enhancement scheme and signal feed through scheme. Logics are carried out and the best power-performance is obtained. Here simulations are done under 90nm technology and the results are tabulated below. In that signal feed through scheme is showing better output than the other flip-flops compared here

Parallel network file systems using authenticated key exchange protocols

The keyestablishment for secure many-to-many communications is very important nowadays. The problem is inspired by the proliferation of large-scale distributed file systems supporting parallel access to multiple storage devices. In this, a variety of authenticated key exchange protocols that are designed to address the issues. This shows that these protocols are capable of reducing the workload of the metadata server and concurrently supporting forward secrecy and escrow-freeness. All this requires only a small fraction of increased computation overhead at the client. This proposed three authenticated key exchange protocols for parallel network file system (pNFS). The protocols offer three appealing advantages over the existing Kerberos-based protocol. First, the metadata server executing these protocols has much lower workload than that of the Kerberos-based approach. Second, two of these protocols provide forward secrecy: one is partially forward secure (with respect to multiple sessions within a time period), while the other is fully forward secure (with respect to a session). Third, designed a protocol which not only provides forward secrecy, but is also escrow-free

Effect of child to child approach on knowledge regarding practices of oral hygiene among school children between 8 to 11 yrs

Oral health may be defined as a standard of health of the oral and related tissues which enables an individual to eat, speak and socialize without active disease, discomfort or embarrassment and which contributes to general wellbeing. OBJECTIVES To assess the effectiveness of child to child approach on knowledge regarding practices of oral hygiene among school children between 8 to 11 yrs METHODS Study design was pre experimental, one group pre test post test only design. Fifty school students were selected by using Non probability convenient sampling technique. The intervention of child to child approach was once daily for seven day and post test was done after seven days. Interview checklist was used to assess the knowledge regarding practices of oral hygiene. RESULTS Statistical findings revealed that the pretest mean score of knowledge was 5.56 with S.D 1.36 and the post test mean score of knowledge was 12.12 with S.D 1.76. The mean difference was 6.56 and the calculated paired ‘t’ value 24.453 was found to statistically significant at p<0.001 level. CONCLUSION The study highlights child to child approach knowledge regarding practices of oral hygiene was effective

Tuning and Locking the Localized Surface Plasmon Resonances of CuS (Covellite) Nanocrystals by an Amorphous CuPdxS Shell

[Image: see text] We demonstrate the stabilization of the localized surface plasmon resonance (LSPR) in a semiconductor-based core–shell heterostructure made of a plasmonic CuS core embedded in an amorphous-like alloyed CuPd(x)S shell. This heterostructure is prepared by reacting the as-synthesized CuS nanocrystals (NCs) with Pd(2+) cations at room temperature in the presence of an electron donor (ascorbic acid). The reaction starts from the surface of the CuS NCs and proceeds toward the center, causing reorganization of the initial lattice and amorphization of the covellite structure. According to density functional calculations, Pd atoms are preferentially accommodated between the bilayer formed by the S–S covalent bonds, which are therefore broken, and this can be understood as the first step leading to amorphization of the particles upon insertion of the Pd(2+) ions. The position and intensity in near-infrared LSPRs can be tuned by altering the thickness of the shell and are in agreement with the theoretical optical simulation based on the Mie–Gans theory and Drude model. Compared to the starting CuS NCs, the amorphous CuPd(x)S shell in the core–shell nanoparticles makes their plasmonic response less sensitive to a harsh oxidation environment (generated, for example, by the presence of I(2))

Comparative study of Bolus and Continuous Infusion of Esmolol on Hemodynamic response to Laryngoscopy, Endotracheal Intubation and Sternotomy in Coronary Artery Bypass Graft Surgery

BACKGROUND AND OBJECTIVE: The aim of this randomized, prospective and double blinded study is to investigate effects of different esmolol use on hemodynamic response of laryngoscopy, endotracheal intubation and sternotomy in coronary artery bypass graft surgery. METHODS: After approval of local ethics committee and patients’ written informed consent, 60 patients were randomized into three groups equally. In Infusion Group; from 10 min before intubation up to 5th minute after sternotomy, 0.5 mg/kg/min esmolol infusion, in Bolus Group; 2 min before intubation and sternotomy 1.5 mg/kg esmolol IV bolus and in Control Group; %0.9 NaCl was administered. All demographic parameters were recorded. Heart rate and blood pressure were recorded before infusion up to anesthesia induction in every minute, during endotracheal intubation, every minute for 10 minutes after endotracheal intubation and before, during and after sternotomy at first and fifth minutes. RESULTS: SAP was being found more in Group B and C than Group. HR was found less in Group B than Group C but no significant difference was found between Group B and Group I. CONCLUSION: This study highlights that esmolol infusion is more effective than esmolol bolus administration on controlling systolic arterial pressure during endotracheal intubation and sternotomy in CABG surgery

INFLUENCE OF WEATHER FACTORS ON INCIDENCE OF SHOOT AND FRUIT BORER (Earias vittella Fabiricus) ON BHENDI

The field experiments were carried out in the farmer field at C. Mutlur near Chidambaram during rabi and kharif 2017. The results of experiments revealed that the per cent shoot damage and fruit damage by E. vittella on bhendi &nbsp;reached peak on 13th and 15th MSW in rabi season, whereas 43rd and 42nd MSW in kharif season. The per cent shoot damage and fruit damage by E. vittella were exerted significantly positively correlated with minimum (0.552 &amp; 0.698) and maximum temperature (0.629 &amp; 0.748), whereas rainfall positively correlated with per cent shoot and fruit damage but it was non significant (0.111 &amp; 0.297), however relative humidity (-0.178 &amp; -0.210) and sunshine hours were exerted negatively correlated with per cent shoot damage and fruit damage by E. vittella during rabi 2017. The kharif season 2017 indicated that per cent shoot damage and fruit damage of bhendi was positively non significant association with RH and rain fall, while negatively non significant correlation with minimum temperature (-0.43 &amp; -0.309) and sunshine hours (-0.265 &amp; -0.283) was recorded
