Forbidding Rank-Preserving Copies of a Poset

The maximum size, La(n,P), of a family of subsets of [n] = {1,2,...,n} without containing a copy of P as a subposet, has been extensively studied. Let P be a graded poset. We say that a family \({\mathcal F}\) of subsets of [n] = {1,2,...,n} contains a rank-preserving copy of P if it contains a copy of P such that elements of P having the same rank are mapped to sets of same size...

Un pseudoproblema para el minimismo

The aim of this paper is to contribute to the debate between contextualism and minimalism. I show that one of the main arguments against minimalism, which I called "argument of loss of generality of the notion of implicature", is based on a misunderstanding or a simplification of the mechanism of generation of conversational implicatures.

Effect of bisphosphonate on temporomandibular joint in osteopenia-induced rats by botulinum toxin A injection on masticatory muscle: a preliminary study

BackgroundBotulinum toxin injection on the masticatory muscle induces the osteopenic condition on the ipsilateral condyle. Bisphosphonate suppresses bone resorption and is used to treat osteopenic or osteoporotic condition. This study aimed to evaluate the effect of bisphosphonate administration on prevention of condylar resorption and botulinum toxin A-induced disuse osteopenia...

Control of glucose metabolism is important in tenogenic differentiation of progenitors derived from human injured tendons

Glucose metabolism is altered in injured and healing tendons. However, the mechanism by which the glucose metabolism is involved in the pathogenesis of tendon healing process remains unclear. Injured tendons do not completely heal, and often induce fibrous scar and chondroid lesion. Because previous studies have shown that tendon progenitors play roles in tendon repair, we asked...

Nebulous objects in the Southern Hemisphere

We have inspected plates of the Southern Hemisphere with the purpose of finding previously unreported nebulous objects. We found 93 objects, of which 62 are associated with IRAS point sources. Some of these objects look like Herbig-Haro objects, while others are cometary nebulae, tight groups of red dwarf stars, and objects resembling small regions of star formation.

Gamma-ray spectrum from thermal neutron capture on gadolinium-157

We have measured the |$\gamma$|-ray energy spectrum from the thermal neutron capture, |${}^{157}$|Gd|$(n,\gamma)$|⁠, on an enriched |$^{157}$|Gd target (Gd|$_{2}$|O|$_{3}$|⁠) in the energy range from 0.11 MeV up to about 8 MeV. The target was placed inside the germanium spectrometer of the ANNRI detector at J-PARC and exposed to a neutron beam from the Japan Spallation Neutron...

Síntese e modificações de derivados heterocíclicos de D-arabinose: potenciais inibidores de glicose-6-fosfato isomerase e de glicosamina-6-fosfato sintase

The synthesis of -5-(D-arabino-1,2,3,4-tetrahydroxybutyl)tetrazole and -2-(D-arabino-1,2,3,4-tetra-acetoxybutyl)-5-methyl-1,3,4-oxadiazole from D-arabinose is described. Attempts at removing the protecting groups of the oxadiazole derivative were unsuccessful, leading to products resulting from the opening of the oxadiazole ring. The unprotected tetrazole derivative was...

Blood parasites of some birds from São Paulo State, Brazil

A total of 3.449 birds, representing 195 species of 33 families from three areas in São Paulo State, Brazil, were examined for hematozoa during the period 1967-1972. Only 268 birds (7.8%) of 21 families harbored a blood parasite, which represented by species of Haemoproteus (3.5%), microfilaria (2.6%), Plasmodium (1.8%), Trypanosoma (0.8%) and Leucocytozoon (0.06%). The...

The Polokwane conference and South Africa's second political transition: Tentative conclusions on future perspectives

In this phase of South Africa's second political transition (manifesting characteristics of political decay) it looks as if the ANC is becoming more dominant, hegemonic and ideological, with added neo-patrimonial tendencies that are becoming more overt in an oligarchic manner. This article analyses the ANC's Polokwane conference (qualitatively and deductively) as part of South...

Mechanism and resistance for antimycobacterial activity of a fluoroquinophenoxazine compound

We have previously reported the inhibition of bacterial topoisomerase I activity by a fluoroquinophenoxazine compound (FP-11g) with a 6-bipiperidinyl lipophilic side chain that exhibited promising antituberculosis activity (MIC = 2.5 μM against Mycobacterium tuberculosis, SI = 9.8). Here, we found that the compound is bactericidal towards Mycobacterium smegmatis, resulting in...

Variabilidade espacial da chuva durante o experimento LBA/TRMM 1999 na Amazônia

The purpose of this work was to study the space variability of the convective rainfall in Amazonia during the LBA/TRMM experiment 1999. A dataset of 37 rain gauges (split in 4 networks and geographically located with a maximum distance amongst them around 50 km) has been used to provide rainfall measurements for the period from mid Dec 1998 until end of Feb 1999, which is the...

This study showed the favorable effect of prebiotic fiber in the survival of Lactobacillus casei of ATCC 393, incorporated in matrices of Andean blackberry by a process of vacuum impregnation and subsequent lyophilization. Blackberry slices were impregnated with isotonic solutions of inulin, fruit - oligosaccharide (FOS) and inulin-FOS control without prebiotic inoculated with...

Estructura y composición florística de la selva alta perennifolia en el ejido Niños Héroes Tenosique, Tabasco, México

Floristic composition and forest structure were described for the tall evergreen tropical forest of the Ejido Niños Heroes, Tenosique, Tabasco (NHT). We selected four sampling units (U), each of which was set up in a box 50 X 50 m (2 500 m2). In each U all trees with a diameter at breast height breast (DBH) ≥ 2.5 cm were counted and measured for height. Density, frequency, and...

Towards a universal concept of vulnerability: Broadening the evidence from the elderly to perinatal health using a Delphi approach

Background The concept 'vulnerability' is prevalent in the public domain, health care, social institutions and multidisciplinary research. Conceptual heterogeneity is present, hampering the creation of a common evidence-base of research achievements and successful policies. Recently an international expert group combined a specific literature review with a 2-stage Delphi...

Community ecology across bacteria, archaea and microbial eukaryotes in the sediment and seawater of coastal Puerto Nuevo, Baja California

Microbial communities control numerous biogeochemical processes critical for ecosystem function and health. Most analyses of coastal microbial communities focus on the characterization of bacteria present in either sediment or seawater, with fewer studies characterizing both sediment and seawater together at a given site, and even fewer studies including information about non...

Relationship Between Vitamin D Status From Childhood to Early Adulthood With Body Composition in Young Australian Adults

Vitamin D plays a role in the differentiation and metabolism of skeletal muscle and, possibly, adipose tissue; however, the relationship between vitamin D status during growth and body composition in early adulthood is unclear.

Mucosal cell populations may contribute to peripheral immune abnormalities in HIV-infected subjects introducing cART with moderate immune-suppression

HIV infection causes the progressive depletion of CD4+ T-lymphocytes and profound modifications of T-cell homeostasis, which persist despite virologically-suppressive treatment and have been linked to a worse clinical outcome. Enduring alterations of the gastrointestinal tract may represent the underlying pathogenic mechanisms of these phenomena. Twenty-six HIV-infected subjects...

Calvins Theologie des Heiligen Geistes

ABSTRACT Calvin's treatment in the Institutes of the reality of Christ, of salvation, of the most existential and fundamental questions of being a Christian - eg. what faith is, how it actually comes into being, how we become aware of it - is preceded by a chapter on the Holy Spirit and his significance for Christian existence and life. What is known or confessed or experienced...
