The precipitation of interstitial oxygen in Czochralski grown silicon has been investigated by infrared absorption spectroscopy, chemical etching, transmission electron microscopy and X-ray diffraction after application of homogenization annealing process called Tabula Rasa.
The influence of this homogenization step consisting in short time annealing at high temperature has been observed for various temperatures and times. The differences in oxygen precipitation, precipitate morphology and evolution of point defects in samples with and without Tabula Rasa applied is evident from all used experimental techniques.
The results qualitatively correlate with prediction of homogenization annealing process based on classical nucleation theory. Maria Montessori and the Secret of Tabula Rasa. The "tabula rasa " of this article's title is a Latin term meaning "clean slate. But on that day,…. The results of these surveys are used by DOE in determining the need for and extent of remedial actions. Heredity of port-wine stains: investigation of families without a RASA 1 mutation.
The prevalence of capillary malformations, also known as port-wine stains PWS , is 0. Familial segregation can occur.
In PWS familial cases, the inheritance is considered to be autosomal dominant with variable penetrance. Investigation of the heredity of PWS among patients who attended the vascular anomaly section at the Department of Dermatology in Malmoe, Southern Sweden, between and and to study the involvement of the RASA 1 gene in patients with a positive family history of PWS. A total of patients were examined and given a questionnaire regarding family history of PWS.
The first group of patients females and 66 males reported a negative family history. PWS may have a stronger heredity component than it was reported earlier and inheritance should be considered when counseling a patient. Oxygen migration enthalpy likely limits oxide precipitate dissolution during tabula rasa. Looney, E. In order to mitigate these defects, a high-temperature homogenization anneal called tabula rasa TR that has been used in the electronics industry is now proposed for use in solar-grade wafers.
This work addresses the kinetics of tabula rasa by elucidating the activation energy governing oxide precipitate dissolution, which is found to be 2. This value is consistent within uncertainty to the migration enthalpy of oxygen interstitials in silicon, implying TR to be kinetically limited by oxygen point-defect diffusion. This large activation energy is observed to limit oxygen precipitate dissolution during standard TR conditions, suggesting that more aggressive annealing conditions than conventionally used are required for complete bulk microdefect mitigation.
We investigate a high temperature, high cooling-rate anneal Tabula Rasa TR and report its implications on n-type Czochralski-grown silicon n-Cz Si for photovoltaic fabrication.
Tabula Rasa aims at dissolving and homogenizing oxygen precipitate nuclei that can grow during the cell process steps and degrade the cell performance due to their high internal gettering and recombination activity. We characterize the bulk lifetime by Sinton lifetime and photoluminescence mapping just after Tabula Rasa , and after the subsequent cell processing. Additionally, we report the efficacy of Tabula Rasa on n-type Cz-Si wafers and its dependence on oxygen concentration, correlated to position within the ingot.
Measurements of hydrographic conditions in the Ponta Rasa tidal mangrove swamp, Inhaca Island, Mozambique were made in August-October during the winter dry season. There is no river discharge into Ponta Rasa and during the observation period, there was no significant rainfall. The mean salinity in the swamp c. Salinity variation c. A model which incorporates tidal dynamics coupled to heat and salt balance equations reproduces many of the observed features of the system.
RASA 1 analysis guides management in a family with capillary malformation-arteriovenous malformation. PubMed Central. Capillary malformation-arteriovenous malformation CM-AVM; MIM is an autosomal dominant disorder characterized by multifocal cutaneous capillary malformations, often in association with fast-flow vascular lesions, which may be cutaneous, subcutaneous, intramuscular, intraosseus, or cerebral arteriovenous malformations or arteriovenous fistulas.
Capillary malformations of the skin are common, and clinical examination alone may not be able to definitively diagnose-or exclude- CM-AVM. We report a family in which the proband was initially referred for a genetic evaluation in the neonatal period because of the presence of a cardiac murmur and minor dysmorphic features.
Both he and his mother were noted to have multiple capillary malformations on the face, head, and extremities. Echocardiography revealed dilated head and neck vessels and magnetic resonance imaging and angiography of the brain revealed a large infratentorial arteriovenous fistula, for which he has had two embolization procedures. We established targeted mutation analysis for the proband's mother and sister, the latter of whom is a healthy 3-year-old whose only cutaneous finding is a facial capillary malformation.
This revealed that the proband's mother is also heterozygous for the RASA 1 mutation, but his sister is negative. Consequently, his mother will undergo magnetic resonance imaging and angiography screening for intracranial and spinal fast-flow lesions, while his sister will require no imaging or serial evaluations. Targeted mutation analysis has been offered to additional maternal family members. This case illustrates the benefit of molecular testing in diagnosis and making screening recommendations for families with CM-AVM.
Stratified settlement and moulting competency of brachyuran megalopae in Ponta Rasa mangrove swamp, Inhaca Island Mozambique. Information on recruitment processes of mangrove crustaceans is very limited, in spite of the great importance of these environments for the coastal zone.
This study describes the settlement patterns of brachyuran crabs at Ponta Rasa mangrove swamp, Inhaca Island, in order to assess if settlement patterns reflect adult distribution. Hoghair filter collectors were deployed at different strata within the mangrove, and at the adjacent intertidal flat as control.
Sampling was conducted daily for a period of 82 days. The collected megalopae were reared in the laboratory to assess their moulting competency and to enable identification. Settlement intensity was tested for association with wind stress, from different directions and averaged over time lags up to 6 days. A total of megalopae settled during this study. Settlers inside Ponta Rasa swamp were exclusively mangrove species. Ilyograpsus paludicola settled mainly among Rhizophora mucronata and the mixed area of Ceriops tagal and Bruguiera gymnorrhiza, where adults occur, and Perisesarma guttatum, the most abundant sesarmid at Ponta Rasa , settled mainly at the creek.
Neosarmatium meinerti settled among Avicennia marina pnematophores, very close to the adult populations. Megalopae of mangrove taxa that settled outside the mangrove took longer to moult than the ones settling inside the swamp. In the intertidal areas of the mangrove, settlers took an average of days to moult, whereas in subtidal areas time to moult was on an average days.
Thus, both distribution of settlers and moulting competency suggest that settling follows adult distribution. Tides have a strong influence on settlement at Ponta Rasa , with the effect that, due to the high sill at the entrance, neap tides do not penetrate the mangrove.
The analysis of settlement data suggested a significant effect of wind-driven transport on onshore migration. Spectroscopic and E-tongue evaluation of medicinal plants: A taste of how rasa can be studied.
The use of medicinal plants in Ayurveda is based on rasa , generally taken to represent taste as a sensory perception. This chemosensory parameter plays an important role in Ayurvedic pharmacology. The aim is to explore the use of structuro-functional information deduced from analytical techniques for the rasa -based classification of medicinal plants in Ayurveda.
Methods of differential sensing and spectroscopic metabolomics have been used in select medicinal plants from three different taste categories sweet, pungent and multiple taste : Tribulus terrestris, Vitis vinifera and Glycyrrhiza glabra from sweet category; Piper longum, Cuminum cyminum and Capsicum annum from pungent group; Emblica officinalis with five tastes.
In terms of taste and phytochemical profiles, all samples were unique but with similarities within each group.
While the sensor response in E-tongue showed similarities within the sweet and pungent categories, NMR spectra in the aromatic region showed close similarities between the plants in the sweet category. The sensory, phytochemical and phytoelemental profiles of E. A combination of sensorial and chemical descriptors is a promising approach for a comprehensive evaluation and fingerprinting of the Ayurvedic pharmacological parameter rasa.

Although, several studies and equations have been published since decades that describe past events and theoretical descriptions, empirical data of what is happening in the snow cover is far less available. A way to fill this gap of empirical data, rain-on-snow-simulators might be of help.
In , Juras et al. The huge advantage of this devise - in contrast to other purely field-based experiments - are their fixed, and mostly standardized conditions and the possibility to measure all required data to monitor the water fluxes and melting processes at a time. Mounted in a convenient location, a large number of experiments are relatively easy conductible.
We applied and further developed the original device and plausified the results of this redesigned version, called RASA. The principal design was borrowed from the original version being a frame with a sprinkler on top and a snow sample in a box at the bottom, from which the outflow is measured with a tipping gauge. We added a moving sprinkling plate to ensure a uniform distribution of raindrops on the snow, and - most importantly - we suspended the watered snow sampled on weighting cells.
The latter enables to continuous measurement of the snow sample throughout the experiment and thus the indirect quantification of liquid water saturation, water holding capacity, and snowmelt amount via balance equations.
As it is remains unclear if this device is capable to reproduce known processes, a hypothesis based plausibility check was accomplished. Thus, eight hypothesizes were derived from literature and tested in 28 experiments with the RASA mounted at m elevation. In general, we were able to reproduce most of the hypotheses. The RASA proved to be a very valuable device that can generate suitable results and has the potential to extend the empirical-experimental data.
Herbo-mineral formulations of Ayurveda contain specified metals or minerals as composition, which have their beneficial effects on biological systems. These metals or minerals are transformed into non-toxic forms through meticulous procedures explained in Ayurveda. Though literature is available on quality aspects of such herbo-mineral formulations; contemporary science is raising concerns at regular intervals on such formulations.
Thus, it becomes mandate to develop quality profiles of all formulations that contain metals or minerals in their composition.
The physico chemical analysis reveals that VKR prepared by following classical guidelines is very effective in converting the macro elements into therapeutically effective medicines in micro form. Well prepared herbo-mineral drugs offer many advantages over plant medicines due to their longer shelf life, lesser doses, easy storing facilities, better palatability etc.
The inferences and the standards laid down in this study certainly can be utilized as baseline data of standardization and QC. Climate factors affecting fertility after cervical insemination during the first months of the breeding season in Rasa Aragonesa ewes. This study was carried out to examine the impact of several climate variables on the pregnancy rate after cervical artificial insemination AI of Rasa Aragonesa ewes. Data were derived from 8, inseminations in 76 well-managed flocks performed during the first month of the breeding season July to October.
The following data were recorded for each animal: farm, year, month of AI, parity, lambing-treatment interval, inseminating ram, AI technician, and climatic variables such as mean, maximum and minimum temperature, mean and maximum relative humidity, rainfall, and mean and maximum temperature-humidity index THI for each day from day 12 before AI to day 14 post-AI.
Means were furthermore calculated for the following periods around AI day 0 : to 0, -2 to 0, AI day, 0 to 2, and 0 to Fertility was also lower for primiparous ewes and in multiparous ewes with more than five previous parturitions. Other factors with significant impact on fertility were flock, technician, inseminating ram, and a lambing-AI interval longer than days.
