A o Isolada ou Combinada de ácidos Organicos e Promotor de Crescimento em Ra es de Frangos de Corte
Garcia RG,Ariki J,Moraes VMB,Kronka SN
Revista Brasileira de Ciência Avícola , 2000,
Abstract: O experimento teve como objetivo verificar a a o da apramicina (10 ppm) e dos ácidos fórmico + propi nico (0,0; 0,1 e 0,2%) no desempenho de frangos de corte sexados. A mistura dos ácidos organicos foi de 1:1. O delineamento foi inteiramente casualizado, em esquema fatorial 2 x 3 x 2 (apramicina x ácidos organicos x sexos), com 4 repeti es de 45 aves por parcela, totalizando 2.160 pintos Cobb de 1 dia. As aves receberam ra o à vontade. Na fase inicial, a adi o da apramicina (10 ppm) e 0,1% dos ácidos organicos, isoladamente, melhorou o ganho de peso das aves. A adi o conjunta dos produtos n o promoveu ganho acumulado. Na presen a da apramicina, a adi o dos ácidos organicos piorou a convers o alimentar. Nas fases final e total, os dados de desempenho n o apresentaram diferen as significativas. O rendimento de carca a foi prejudicado com a adi o conjunta da apramicina e 0,1% dos ácidos organicos.
Integrated GIS, Remote Sensing and Survey Data for Damage Assessment of Buildings in Tsunami Event, Ishinomaki City, Japan  [PDF]
Mohammad Reza Poursaber, Yasuo Ariki
Journal of Geographic Information System (JGIS) , 2016, DOI: 10.4236/jgis.2016.82023
Abstract: The 2011 Tsunami event in the eastern coastal area of Japan caused a huge amount of damages or devastations on buildings. To this date, several field surveys have been conducted which provide detailed information about inundation areas and building damage characteristics in attacking east coastal areas by this tsunami. In this study, building damage data of Ishinomaki city, with special attention to the plain coast affected area, are classified and analyzed using data surveyed by the Ministry of Lands, Infrastructure and Transportation of Japan (MLIT) for more than 52,000 structures. The classification includes information on six levels of damage, four types of building materials and damages due to tsunami inundation for each building material which are necessary information for an effective hazard mitigation. Notably, damage level percentage distribution of different building materials is plotted for different inundation depth ranges in several sets of figures. This graphic illustration not only shows a better resistant performance of Reinforced Concrete (RC) and steel buildings over wood or other buildings for all inundation depth ranges, but also can explain clearly the inundation-induced damage behavior for each building material as well as the threshold depth for each damage level. Moreover, this research contains an analysis of vulnerable areas due to the coastal topography and the geographical factors. Surveyed data provided by Geospatial information authority of Japan (GSI) that classifies Ishinomaki plain coast area into three classes are compared with the damage map produced using an Analytical Hierarchy Process (AHP) methodology in ArcGIS 10.2 environment. The influence of key geographical features on tsunami-induced building damage, notably Kitakami river and water canals flooding, is taken into account with respect to the weighting of factors. A good agreement produced building damage map with surveyed GSI data shows the power of a GIS tool based on the AHP approach for tsunami damage assessment. The results of this study are useful to understand the damage behavior of buildings with different structural materials located in coastal areas vulnerable to the tsunami disaster.

Abstract: We prove the modular branching rule of the cyclotomic Hecke algebras, which has remained open.
Finite dimensional Hecke algebras
Susumu Ariki
Mathematics , 2007,
Abstract: These are notes prepared for ICRA workshop at Torun, Poland, August 2007. In the first part, we explain results on canonical basic sets by Geck and Jacon and propose a categorification framework which is suitable for our example of Hecke algebras. In the second part, we review basics of Kashiwara crystal and explain the Fock space theory of cyclotomic Hecke algebras and its applications. In the third part, we explain Rouquier's theory of quasihereditary covers of cyclotomic Hecke algebras. We add detailed explanation of the proofs here. The third part is based on my intensive course given at Nagoya university in January 2007.
Graded $q$-Schur algebras
Susumu Ariki
Mathematics , 2009,
Abstract: Generalizing recent work of Brundan and Kleshchev, we introduce grading on Dipper-James' $q$-Schur algebra, and prove a graded analogue of the Leclerc and Thibon's conjecture on the decomposition numbers of the $q$-Schur algebra when $q^2\neq1$ and $q^3\neq1$.
Robinson-Schensted correspondence and left cells
Susumu Ariki
Mathematics , 1999,
Abstract: Although the Robinson-Schensted-Knuth correspondence is a classical subject, its study is still active because of new development in last two decades. In this field, fundamental results are sometimes proved by using machineries which may be bypassed. Hence we still feel a lack of good source for these elementary materials. This paper is intended to fill in this lack about the RSK correspondence and the left cells of the symmetric group. It is mostly survey-like, but shows the variety of fields the RSK correspondence is related to.
Representation type for block algebras of Hecke algebras of classical type
Susumu Ariki
Mathematics , 2015,
Abstract: We find representation type of the cyclotomic quiver Hecke algebras of level two in affine type A. In particular, we have determined representation type for all the block algebras of Hecke algebras of classical type (except for characteristic two in type D), which has not been known for a long time.

Some remarks on A_1^{(1)} soliton cellular automata
Susumu Ariki
Mathematics , 2000,
Abstract: In this short note, we describe the A_1^{(1)} soliton cellular automata as an evolution of a poset. This allows us to explain the conservation laws for the A_1^{(1)} soliton cellular automata, one given by Torii, Takahashi and Satsuma, and the other given by Fukuda, Okado and Yamada, in terms of the stack permutations of states in a very natural manner. As a biproduct, we can prove a conjectured formula relating these laws.
