Somalis Barros & Oliveira 2023, n. gen.
No full textSomalis n. gen. Type species: Somalis piauiensis n. gen. n. sp. By the present designation. Etymology: This genus is dedicated to the paleontologist Maria Somália Sales Viana, in recognition of her extensive contributions to the studies of geology and paleontology of the Araripe Basin, as well as Brazilian fossils. Gender feminine. Diagnosis: Carapace with antennal and branchiostegal spines. Long rostrum, with thirteen evident dorsal spines yielding a serrate appearance. Laminar scaphocerite large, lateral margin weakly rounded, longer than rostrum. Pleura of second pleonal somite overlapping the third but not the first. First and second pleonal somites approximately the same size, the third slightly larger, and the fourth and fifth approximately the same size. Sixth somite elongated and approximately twice the length of the previous somites. Telson smaller than uropods, with the lateral margin weakly rounded.Published as part of Barros, Olga Alcântara & Oliveira, Paulo Victor De, 2023, New Dendrobranchiata fossil preserved in the Brazilian Cretaceous (Aptian / Albian) from the Araripe Basin, Piauí State, pp. 545-563 in Zootaxa 5264 (4) on pages 549-550, DOI: 10.11646/zootaxa.5264.4.5, http://zenodo.org/record/783710
Barreras actitudinales de los y las docentes de aula regular sobre la inclusión de estudiantes con necesidades educativas especiales permanentes en el Colegio Rural AgrÃcola Cuncumén Gonzalo Barros Amunátegui 2018
No full textTesina para optar al grado académico de licenciada/o en educaciónLa siguiente investigación, pretende indagar sobre las barreras actitudinales que presentan los y las docentes de aula regular, frente a la inclusión de estudiantes con necesidades educativas especiales permanentes, en el Colegio Rural AgrÃcola Cuncumén Gonzalo Barros Amunátegui. El estudio aplicó un enfoque de investigación de tipo mixto, puesto que aborda la comprensión de los fenómenos desde un análisis cuantitativo con técnicas cualitativas. A su vez, consideró un alcance exploratorio, en el entendido de la escasa información sobre la temática; empleando encuestas y entrevistas a directivos, profesionales del equipo PIE y docentes de aula regular con el fin de obtener una mirada objetiva de los procesos que se están efectuando en el establecimiento. Se espera que esta investigación contribuya a conocer y comprender la situación actual del sistema educacional chileno y en mayor interés, las barreras o dificultades que demuestran los/as docentes, frente a los procesos que implica la educación inclusiva en zonas rurales

Dual Hierarchy for Gravitational n-body
No full textThe n-body problem is the simulation of pair-wise interactions between n objects. This problem appears in many forms, with the classic example being the modeling of gravitational forces between point masses, necessary for cosmological simulations. Many approximation approaches have been devised to reduce the complexity of this problem.t-SNE is a data visualization method that requires repeatedly solving a variant of the n-body problem. A recent paper (An Efficient Dual-Hierarchy t-SNE Minimization, van de Ruit et. al.) proposes a novel algorithm that outperforms other t-SNE minimization methods on medium-scale datasets. The report proves the viability of a dual-traversal method that uses an embedding tree to emit forces and an independent field tree to collect forces. Because the embedding tree is a Linear-BVH and the field tree is an orthtree built to a fixed depth, the overall algorithm has linear complexity.This thesis demonstrates how the dual-tree approach can be adapted for gravitational n-body simulations. Following this, it measures the performance against similar implementations of other algorithms and shows that while the adapted Dual Hierarchy approach is faster than Barnes-Hut, it is outperformed by the Fast Multipole Method on realistic large-scale cosmological datasets.https://github.com/JacksonCampolattaro/n-body Git repository containing an implementation of the adapted Dual Hierarchy algorithm for Gravitational n-body, as well as implementations of several other common algorithms compared against during benchmarking.Computer Engineerin

A note on mapping class group actions on derived categories
No full textLet Xnbe a cycle of n projective lines and Tn a symplectic torus with n punctures. Using the theory of spherical twists introduced by Seidel and Thomas, the author will define an action of the pure mapping class group of Tn on Db(Coh(Xn)). The motivation comes from homological mirror symmetry for degenerate elliptic curves, which was studied by the author with Treumann and Zaslow
Reactions of n,n-dibromobenzenesulfonamide with alcohols and mercaptans, 1971
No full textN,N-Dibromobenzenesulfonamide reacts with primary alcohols in a 1:2 molar ratio to yield the esters of the alcohols. The reaction is believed to proceed via a free radical mechanism to generate the reac-tive acylbromide species which then reacts with another mole of the alcohol to yield the ester as the final product. Benzyl alcohol and short chain primary alcohols give the corresponding aldehydes as side reactions. NNDBS reacts with secondary alcohols to give ketones and alpha bromoketones. No reaction takes place with tertiary alcohols. N,N-Dibromobenzenesulfonamide reacts with primary, secondary and tertiary mercaptans to yield the disulfide of the mercaptans in each case. When molecular bromine was used as the brominating agent, the alcohols did not react but the corresponding disulfide was obtained from each mercaptan
