Second-order cone programming formulations for a class of problems in structural optimization
No full textThis paper provides efficient and easy to
implement formulations for two problems in structural
optimization as second-order cone programming
(SOCP) problems based on the minimum compliance
method and derived using the principle of complementary
energy. In truss optimization both single and
multiple loads (where we optimize the worst-case compliance)
are considered. By using a heuristic which is
based on the SOCP duality we can consider a simple
ground structure and add only the members which
improve the compliance of the structure. It is also
shown that thickness optimization is a problem similar
to truss optimization. Examples are given to illustrate
the method developed in this pape

From the original collection label (Ind. Or. P. Castets), the only thing we are sure of is that the place of the collection lies towards South India. According to the distribution of other species, Castets documented during the expeditions (Desutter-Grandcolas & Jaiswara 2012, Online catalogue of MNHN Paris type specimens) it has to be from the peninsular region (forested hills of Kerala and Tamil Nadu). The Narrower type locality is Eravikulam NP, where the paratype male was collected (Figure 3, Figure 11). The species inhabits dense rainforests of the Western Ghats. It can be found on tree trunks where it probably feeds on mosses and detritus. It is thus a bark dwelling, corticolous species, not a leaf-litter species like <i>Deltonotus subcucullatus</i> and <i>D. gibbiceps</i></p> <p> <b>Derivatio nominis</b>: In Hindu mythology and epics like Mahabharata and Ramayana, <i>trishula,</i> with a trident known as <i>trishulank</i>, originally from Sanskrit, is a three-pronged spear that Lord Shiva used as his sacred weapon to fight off evil. Each tooth of the trishula is called a <i>guna</i> in Samkhya philosophy. Three <i>gunas</i> are in this new species made of the highly compressed median carina and elevated curved external (large trishula) and internal (small trishula) lateral carinae of the pronotal apex.</p> <p> <b>Specific diagnosis.</b> Nanopronotal, small and wingless species (body length from the apex of fastigium to the top of the ovipositor 7.5 mm); vertex, in frontal view, depressed; antennal grooves situated below the lower margin of the compound eyes; scutellum as wide as a single antennal groove; frontal costa bifurcation located on the level of the lower margins of the compound eyes; frontal costa above bifurcation long; median carina of the vertex, lateral carinae of the vertex and transverse carinae projected as equally high horns; FM small, PM+MM1 compressed and highly elevated, MML1 and MML2 strong; VL projected downwards-outwards with rounded apex; strongly incurved external lateral carinae; internal lateral carinae forming with median carina acute upwards directed structure reminding of <i>trishula</i>; all femora armed with sharp teeth; pronotum not covering the whole abdomen; visible part of the abdomen armed. The species can easily be distinguished from <i>T. prashadi</i> and <i>T. pelops</i> by the lack of ventrolateral spines, but also by the morphology of the head and pronotal discus.</p>Published as part of <i>Bhaskar, Dhaneesh, Stermšek, Sara, Easa, P.

The effective Poisson ratio of random cellular matter having bending dominated architecture
No full textWe argue that the effective Poisson ratio of cellular and porous solids is independent
of the material of the solid phase, if the mechanism of the cell wall deformation is dominated
by beam bending —thus rendering it to be a purely kinematic quantity. Introducing a kinematic
simplification and requiring statistical isotropy, we prove a result of remarkable generality that the effective Poisson ratio of irregular planar structures equals 1 for all bending dominated random architectures. We then explore a deeper connection of this behavior with area-preserving deformation of planar closed elastic cells. We show that thin sheets and films made of such
microstructured material afford physical realizations of the two-dimensional analogue of incompressible matter.We term such non-stretchable sheet material as well as deformations as isoektasic

REALISMO CRÍTICO E HISTÓRIA: : ENSAIO SOBRE AS CONVERGÊNCIAS ENTRE E. P. THOMPSON E ROY BHASKAR
No full textThis essay investigates the theoretical convergences between English historian Edward Palmer Thompson and philosopher Roy Bhaskar, particularly in developing alternative realist epistemologies. The text argues that despite Thompson not being a philosopher by training, his capacity to engage in high-level theoretical debates allows for productive dialogue with Bhaskar's "dialectical critical realism." The analysis focuses on three fundamental aspects: first, the ontological conception of multiple interacting layers of reality, where both authors defend a stratified reality that includes the past, possible futures, moral values, and feelings as material forces; second, the necessary differentiation between epistemology and ontology, rejecting the reduction of being to knowledge; and third, the dialectical tension between provisional totality and singularity in the process of knowledge. Both thinkers combat the supposed antitheses between materiality/values, particularity/totality, and subjectivity/objectivity, proposing open, relational ontologies in permanent movement. The essay concludes that Thompson and Bhaskar share an alternative realist perspective that recognizes reality's autonomy in relation to the knowing subject, without falling into naive realism, always maintaining the productive tension between knowledge and reality.Este ensaio investiga as convergências teóricas entre o historiador inglês Edward Palmer Thompson e o filósofo Roy Bhaskar, particularmente no desenvolvimento de epistemologias realistas alternativas. O texto argumenta que, apesar de Thompson não ser filósofo de formação, sua capacidade de engajar-se em debates teóricos de alto nível permite estabelecer diálogo produtivo com o "realismo crítico dialético" de Bhaskar. A análise concentra-se em três aspectos fundamentais: primeiro, a concepção ontológica de múltiplas camadas do real em interação, na qual ambos autores defendem uma realidade estratificada que inclui o passado, os futuros-possíveis, os valores morais e os sentimentos como forças materiais; segundo, a diferenciação necessária entre epistemologia e ontologia, rejeitando a redução do ser ao conhecimento; e terceiro, a tensão dialética entre totalidade provisória e singularidade no processo de conhecimento. Ambos os pensadores combatem as supostas antíteses entre materialidade/valores, particularidade/totalidade, subjetividade/objetividade e propõem ontologias abertas, relacionais e em movimento permanente. O ensaio conclui que Thompson e Bhaskar compartilham uma perspectiva realista alternativa que reconhece a autonomia da realidade em relação ao sujeito cognoscente, sem cair no realismo ingênuo, mantendo sempre a tensão produtiva entre conhecimento e realidade
Pulmonary Drug Delivery System: A Review
No full text<p>Abstract</p><p>Growing attention has been given to the potential of pulmonary root as an alternative for noninvasive systemic delivery of therapeutic agents. Pulmonary drug delivery can be used as an alternative to oral delivery. The system can be best utilized for both local and systemic actions. Pulmonary Drug Delivery System (PDDS) is an important research area which impacts the treatment of illness including asthma, chronic obstructive pulmonary disease (COPD) and various other diseases. Inhalation gives the most direct access to the drug target. This route can be used to deposit the drug to the target site at the high concentration reducing the amount of drug given to the patient and help in reducing systemic side effects and first pass metabolism. Generally, half of all pharmaceuticals are not soluble in water, but are soluble in lipid. As the lungs can absorb both water and oil into the tissue this is not a restriction of pulmonary delivery.</p><p>Keywords</p><p>Pulmonary Drug Delivery System, COPD, Systemic, Inhalation</p>

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
