Utilization of Ecosand and Flyash in Aerated Concrete for a Richest Mix Design
Keertana. B,Sini Sara Mani,M. Thenmozhi
International Journal of Engineering Science and Technology , 2011,
Abstract: Aerated concrete is made by introducing air or gas into slurry composed of portland cement and finely crushed siliceous filler, so that when the mix sets and hardens uniformly cellular structure is formed. Thus it is a mixture of water, cement and finely crushed sand. By using finely powdered metal aluminium powder with the slurry and made to react with the calcium hydroxide liberated during the hydration process to give out large quantity of hydrogen gas. This hydrogen gas when contained in the slurry mix gives the cellular structure. This study involves the use of fly ash eco-sand, a byproduct of cement as filler material, aluminium powder as metalpowder, hydrogen peroxide as foaming agent and OPC 43 grade cement as binder. This product emphasizes its economic feasibility when compared with the commonly produced AAC.
Low pressure migmatites from the Sanandaj-Sirjan Metamorphic Belt in the Hamedan region (Iran)
Ali A. Sepahi, Seyedeh R. Jafari, Sara Mani-Kashani
Geologica Carpathica , 2009, DOI: 10.2478/v10096-009-0007-2
Abstract: Migmatites with evidence for low pressure metamorphism and partial melting occur adjacent to the Alvand Plutonic Complex in the Hamedan region of Iran. They show stromatic, schollen, diktyonitic and massive structure. Sillimanite/andalusite/(kyanite)-garnet- and cordierite-K-feldspar-andalusite-spinel-bearing migmatites are the most common rock types. Some of the granitic intrusions contain xenocrysts which resemble the porphyroblasts of nearby migmatites (e.g. sillimanite, andalusite, cordierite and garnet). Although migmatitic rocks of the region are located near the granitic intrusions, the degree of partial melting is not related to intrusions and is irregular. It appears that partial melting and migmatization pre-date the intrusion of major granitic bodies in the region. Leucosomes in stromatic migmatites are commonly parallel to bedding planes and are mostly formed by metamorphic segregation and/or in situ partial melting (showing mafic selvedges, pinch and swell structures). The melt fraction and migmatite type depend on the chemical composition of parent rocks and the distribution of high strain zones. The formation of thin leucosomes in the stromatic migmatites was controlled by short-range melt movement along the grain boundaries. Melt-rich layers are constrained by pre-existing compositional layering and foliation. Peak metamorphic conditions of ~650 °C and ~300 MPa are consistent with the observed mineral assemblages and the presence of melt in the investigated migmatites.
Intuitionistic Fuzzy α-Generalized Closed Sets in Terms of Minimal Structure Spaces  [PDF]
Mani Parimala, Sivaraman Murali
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.78130
Abstract: In this paper, we introduce the notion of intuitionistic fuzzy α-generalized closed sets in intuitionistic fuzzy minimal structure spaces and investigate some of their properties. Further, we introduce and study the concept of intuitionistic fuzzy α-generalized minimal continuous functions.
Advances in Oligoprotection  [PDF]
Hong Liao, Dixit Sanjaya Mani
Neuroscience & Medicine (NM) , 2011, DOI: 10.4236/nm.2011.22014
Abstract: Oligodendrocytes, the myelinating glial cells of the nervous system, in various disease states display great vulnerability to excitotoxic damage, oxidative stress, and inflammatory cytokines. Besides demyelinating diseases where oligoden-drocyte injury is primarily implicated, damage to them also occurs secondarily in various neuropathies. Oligoprotec-tion should, therefore, be looked into something not just as a means for protecting oligodendrocytes alone but also as a common target of protecting neurons and the neurogliovascular unit as a whole. In this review, we provide a descrip-tion on oligodendrocytes, the reasons for their vulnerability, the evolving new concepts of protecting neurovascular unit and recently neurogliovascular unit; the various diseases where oligodendrocyte injury is implicated with a brief idea on different injury mechanisms of oligodendrocytes. Finally, we present the summary of the drugs that have shown promising results in protecting oligodendrocytes or in protecting white matter as a whole in different in-vivo and in-vitro models.
Photocatalytic Degradation of 2,6-Dichlorophenol in Aqueous Phase Using Titania as a Photocatalyst  [PDF]
Sushil Kumar Kansal, Mani Chopra
Engineering (ENG) , 2012, DOI: 10.4236/eng.2012.48055
Abstract: The paper includes the studies on photocatalytic degradation of 2,6-DCP in aqueous phase using titania (PC-105) as a photocatalyst. The degradation experiments were carried out by irradiating the aqueous suspensions of the model compound in the presence of photocatalysts under UV light. The rate of degradation was estimated from residual concentration spectrophotometrically. Various parameters affecting the degradation process viz. catalyst dose, pH, initial substrate concentration and time were investigated in order to obtain their optimum values. The maximum degradation of 2,6-DCP was achieved with 1.25 g/L catalyst dose at pH-4. The disappearance of 2,6-DCP obeyed pseudo-first order kinetics and the rate constant value was calculated to be 4.78 × 10-4s-1.
A Cooperative Diversity Analysis of Two User Mobile Communication System with Maximal Ratio Combining  [PDF]
Sateeshkrishna Dhuli, V. V. Mani
Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.52014
Abstract:

Cooperative communication is going to play a vital role in the next generation wireless networks. In this paper we derive the expression for symbol error probability (SEP) of a two-user cooperative diversity system, where two users cooperate through the decode-and-forward (DF) relaying with binary phase-shift keying (BPSK) modulation in a flat Rayleigh fading environment. We compare the computational results obtained by the SEP expression with the simulation results using maximal-ratio combining (MRC), equal-gain combining (EGC) and selection combining (SC) techniques. Numerical results show the performance of a cooperative diversity system with maximal-ratio combining is giving better results compared to SC and EGC techniques.

Mani? Emilija
Glasnik Srpskog Geografskog Dru?tva , 2006, DOI: 10.2298/gsgd0602151m
Abstract: Geographical information systems are in use in business application for a long time, but their usage in agriculture is well known, too. This article shows the main structure of geographical information systems for decision support (spatial decision support systems) as advanced GIS technologies made for solving complex, semistructured or nonstructured problems and their application in the agriculture sector. GIS-based technologies has been reviewed through several examples of their use in agriculture and special respect has been given to the precision farming concept, giving short insight into SSToolbox software (SST). The last part of the article is dedicate to the possible usage of GIS-based technologies in the Serbian agriculture.
The position of the Hungarian national minority in Vojvodina: Sociological and legal aspects
Mani? ?eljka
Sociologija , 2011, DOI: 10.2298/soc1103345m
Abstract: The text is about sociological and legal analysis of the position of the Hungarian national minority in Vojvodina, with special regard to the period between 2002 and 2007. It is believed that ethnic relations have a significant role in establishing national identity, and that collective rights represent the legitimate effort to preserve the language, writings and culture of those ethnic groups. The position of the Hungarian national minority is the position that is guaranteed by the constitution of the Republic of Serbia in the section regarding the collective rights: the right to the education in their first language, official use of language and writing, media information's in first language, preservation of culture and the right to participate in public activities. The position of Hungarian minority is regarded in two dimensions: the level of legal regulations and the level of actual problems that the members of minority are facing when practicing their rights.
Evaluation of morphological diversity in south Indian tea clones using statistical methods
Mani Ramakrishnan
Maejo International Journal of Science and Technology , 2011,
Abstract: Morphological diversity of three Camellia (Theaceae) taxa conserved in an ex situ gene bank was studied and the importance of different descriptors in categorising accessions into distinct groups was also determined. Twelve accessions were characterised using 15 morphological descriptors of IPGRI guidelines. The results of principal component analysis (PCA) on morphological characters showed that the first two principal components accounted for 44.77 % of the total variance. In the evaluated quantitative characters, all three taxa had a coefficient of variation (CV) greater than 24.85%, and within the taxon the CV was greater than 9.59%. The qualitative characters showed a wide range of variations and yielded significant differences (p<0.05). Phenotypic data had high contributing component loadings from characters such as leaf area, weight of harvested shoots, stem colour, leaf pubescence and young shoot colour. Cluster analysis delineated the accessions into three groups. The implications of our results hold promise for assessing genetic diversity in germplasm collections, which is a prerequisite for their utilisation, effective management and crop improvement.

Mani? Samir
Medjunarodni Problemi , 2012, DOI: 10.2298/medjp1201082m
Abstract: The author analyzes the regulation of institutes of responsibility for dishonest conducting of negotiations in normative acts of certain EU countries and the Balkans. He analyzes the rules of behavior of parties during negotiations established through the court practice and theory in Switzerland, Germany, France and Hungary. In the paper the regulations of the most significant secondary sources of Contract Law have also been included and they are as follows: the Principles of European Contract Law (PECL) and Common Conceptual Framework (DCFR). Because of the great role in the regulation of pre-contract relationships, the author has devoted considerable attention to the principle of scruple and honesty.
