The Thermal Conductivity: An Alternative Method for the Measurement of Soil Compaction

Four treatments of tillage were compared by measuring soil thermal conductivity. Bulk density and difference between treatments pointed to the discriminatory capacity of the method. The soil thermal conductivity measure or Electrothermal Method (EM) has demonstrated to be a new and reliable indicator for the compaction state of soil

La Educación Financiera y su Contribución al Desarrollo Sustentable en México

La Educación Financiera y su Contribución al Desarrollo Sustentable en MéxicoMéxico es uno de los 196 Estados miembros de la ONU que se ha comprometido con la búsqueda del desarrollo sustentable. Sin embargo, una de las principales dificultades que enfrenta para poder lograr este objetivo se encuentra en promover el bienestar financiero, esto es debido a los altos niveles de pobreza y desigualdad económica que existen entre sus habitantes. Lo anterior, es un claro resultado de un nivel de ingreso poco competitivo, un sistema financiero que ha demostrado ser poco atractivo, un evidente atraso en el desarrollo de la educación financiera y de políticas públicas que no han demostrado ser efectivas. Por ello, el presente estudio plantea la necesidad de que los propios individuos se conviertan en agentes de cambio y contribuyan a lograr su propio bienestar financiero y una mayor equidad. Para lograr esto, la educación financiera es una herramienta administrativa que contribuye con diversas estrategias para la administración de la economía familiar, como es el manejo adecuado de los ingresos y disminución de las deudas, favoreciendo el ahorro y fomentando en medida de lo posible la inversión. Por lo tanto, la educación financiera contribuye en el logro del bienestar financiero ya que provee conocimientos que permiten el desarrollo de habilidades para la correcta toma de decisiones financieras, lo cual impacta en la reducción de la desigualdad y la pobreza y contribuye con el desarrollo sustentable

Peripheral giant cells granuloma as a rare early manifestation of primary hyperparathyroidism

Primary hyperparathyroidism occurs due to parathyroid adenoma, which as initial presentation in most cases includes recurrent nephrolithiasis (10-25%). Giant cell tumors (GDD) also called osteoclastomas or brown tumors affect the second decade of life and are currently a rare manifestation of primary hyperthyroidism. The incidence of lesion appearance in the maxillary bones is 4.5%. We presented the case of a 36 year old female patient with history of hypertension, who developed an increase in volume in the right maxillary region of 4×3 cm, with incapability of complete occlusion of dental arch, solid dysphagia, biopsy was performed with peripheral giant cells granuloma as a result, PTH serum levels were requested, with result of 1175 pg/ml and serum calcium of 13.24 mg/dl. Parathyroid gammagram was performed with hyperfunctioning parathyroid tissue. Patient underwent a selective parathyroidectomy. She had an adequate postoperative evolution and was discharged without complications. The patient had adequate follow up by head and neck surgery in external consultation, serum calcium 7.66 mg/dl, decrease of volume in right maxillary region to 3×3 cm; pathology report with parathyroid adenoma. Surgical treatment of brown tumor is still pending by the maxillofacial surgery department

Connection between genetic polymorphism of interleukin -1 beta with chronic periodontitis in peruvian adults

Objectives. To determine the connection between polymorphism IL-1B C(+3953/4)T and chronic periodontitis in adults. Materials and Methods. Case and control study. Individuals between 18 and 64 years of age were included; they were recruited through healthcare campaigns carried out in 2012 in different areas of the city of Lima with similar socio-economic characteristics. Dentists specialized in periodontics performed the diagnosis of the periodontal state of participants; genotyping was made through the PCR-RFLP technique. The data were analyzed by logistic regression. Results. The factors associated with chronic periodontitis were: age over 46 years (OR: 7.50, CI 95%: 1.85-6.37), higher education level achieved (OR: 0.43, CI 95%: 0.27-0.98), the presence of allele 2 in the polymorphism of IL-1B. The positive genotype (2-2) was associated with the presence of chronic periodontitis (OR: 2.06, CI 95%: 1.01-4.21). Conclusions. The presence of allele 2 in the polymorphism of IL-1B and the positive genotype (2-2) confers greater risk for the development of chronic periodontitis in the population of Peruvian adults under study

Constraints on dark matter-nucleon effective couplings in the presence of kinematically distinct halo substructures using the DEAP-3600 detector

DEAP-3600 is a single-phase liquid argon detector aiming to directly detect Weakly Interacting Massive Particles (WIMPs), located at SNOLAB (Sudbury, Canada). After analyzing data taken during the first year of operation, a null result was used to place an upper bound on the WIMP-nucleon spin-independent, isoscalar cross section. This study reinterprets this result within a Non-Relativistic Effective Field Theory framework, and further examines how various possible substructures in the local dark matter halo may affect these constraints. Such substructures are hinted at by kinematic structures in the local stellar distribution observed by the Gaia satellite and other recent astronomical surveys. These include the Gaia Sausage (or Enceladus), as well as a number of distinct streams identified in recent studies. Limits are presented for the coupling strength of the effective contact interaction operators $\mathcal{O}_1$, $\mathcal{O}_3$, $\mathcal{O}_5$, $\mathcal{O}_8$, and $\mathcal{O}_{11}$, considering isoscalar, isovector, and xenonphobic scenarios, as well as the specific operators corresponding to millicharge, magnetic dipole, electric dipole, and anapole interactions. The effects of halo substructures on each of these operators are explored as well, showing that the $\mathcal{O}_5$ and $\mathcal{O}_8$ operators are particularly sensitive to the velocity distribution, even at dark matter masses above 100 GeV/$c^2$

Search for dark matter with a 231-day exposure of liquid argon using DEAP-3600 at SNOLAB

DEAP-3600 is a single-phase liquid argon (LAr) direct-detection dark matter experiment, operating 2 km underground at SNOLAB (Sudbury, Canada). The detector consists of 3279 kg of LAr contained in a spherical acrylic vessel. This paper reports on the analysis of a 758  tonne⋅day exposure taken over a period of 231 live-days during the first year of operation. No candidate signal events are observed in the WIMP-search region of interest, which results in the leading limit on the WIMP-nucleon spin-independent cross section on a LAr target of 3.9×10−45  cm2 (1.5×10−44  cm2) for a 100  GeV/c2 (1  TeV/c2) WIMP mass at 90% C.L. In addition to a detailed background model, this analysis demonstrates the best pulse-shape discrimination in LAr at threshold, employs a Bayesian photoelectron-counting technique to improve the energy resolution and discrimination efficiency, and utilizes two position reconstruction algorithms based on the charge and photon detection time distributions observed in each photomultiplier tube

The liquid-argon scintillation pulseshape in DEAP-3600

DEAP-3600 is a liquid-argon scintillation detector looking for dark matter. Scintillation events in the liquid argon (LAr) are registered by 255 photomultiplier tubes (PMTs), and pulseshape discrimination (PSD) is used to suppress electromagnetic background events. The excellent PSD performance of LAr makes it a viable target for dark matter searches, and the LAr scintillation pulseshape discussed here is the basis of PSD. The observed pulseshape is a combination of LAr scintillation physics with detector effects. We present a model for the pulseshape of electromagnetic background events in the energy region of interest for dark matter searches. The model is composed of (a) LAr scintillation physics, including the so-called intermediate component, (b) the time response of the TPB wavelength shifter, including delayed TPB emission at O(ms) time-scales, and c) PMT response. TPB is the wavelength shifter of choice in most LAr detectors. We find that approximately 10% of the intensity of the wavelength-shifted light is in a long-lived state of TPB. This causes light from an event to spill into subsequent events to an extent not usually accounted for in the design and data analysis of LAr-based detectors

The bHLH transcription factor SPATULA enables cytokinin signaling, and both activate auxin biosynthesis and transport genes at the medial domain of the gynoecium

[EN] Fruits and seeds are the major food source on earth. Both derive from the gynoecium and, therefore, it is crucial to understand the mechanisms that guide the development of this organ of angiosperm species. In Arabidopsis, the gynoecium is composed of two congenitally fused carpels, where two domains: medial and lateral, can be distinguished. The medial domain includes the carpel margin meristem (CMM) that is key for the production of the internal tissues involved in fertilization, such as septum, ovules, and transmitting tract. Interestingly, the medial domain shows a high cytokinin signaling output, in contrast to the lateral domain, where it is hardly detected. While it is known that cytokinin provides meristematic properties, understanding on the mechanisms that underlie the cytokinin signaling pattern in the young gynoecium is lacking. Moreover, in other tissues, the cytokinin pathway is often connected to the auxin pathway, but we also lack knowledge about these connections in the young gynoecium. Our results reveal that cytokinin signaling, that can provide meristematic properties required for CMM activity and growth, is enabled by the transcription factor SPATULA (SPT) in the medial domain. Meanwhile, cytokinin signaling is confined to the medial domain by the cytokinin response repressor ARABIDOPSIS HISTIDINE PHOSPHOTRANSFERASE 6 (AHP6), and perhaps by ARR16 (a type-A ARR) as well, both present in the lateral domains (presumptive valves) of the developing gynoecia. Moreover, SPT and cytokinin, probably together, promote the expression of the auxin biosynthetic gene TRYPTOPHAN AMINOTRANSFERASE OF ARABIDOPSIS 1 (TAA1) and the gene encoding the auxin efflux transporter PIN-FORMED 3 (PIN3), likely creating auxin drainage important for gynoecium growth. This study provides novel insights in the spatiotemporal determination of the cytokinin signaling pattern and its connection to the auxin pathway in the young gynoecium.IRO, VMZM, HHU and PLS were supported by the Mexican National Council of Science and Technology (CONACyT) with a PhD fellowship (210085, 210100, 243380 and 219883, respectively).
