Palatal Obturator

Objective To determine the immediate and longer-term effect(s) on tongue movement following the placement of an experimental opening through a palatal obturator (replicate of subject's prosthesis) worn by an adult male with an unrepaired cleft of the hard and soft palate. Methods Tongue movements associated with an anterior experimental opening of 20 mm2 were examined under three conditions: a control condition in which the subject wore the experimental obturator completely occluded, a condition immediately after drilling the experimental openings through the obturator, and a condition after 5 days in which the subject wore the experimental obturator with the experimental opening. An Electromagnetic Articulograph was used for obtaining tongue movements during speech. Results The findings partly revealed that the immediate introduction of a perturbation to the speech system (experimental fistula) had a temporary effect on tongue movement. After sustained perturbation (for 5 days), the system normalized (going back toward control condition's behavior). Perceptual data were consistent with kinematic tongue movement direction in most of the cases. Conclusions Although the immediate response can be interpreted as indicative of the subject's attempts to move the tongue toward the opening to compensate for air loss, the findings following a sustained perturbation indicate that with time, other physiological adjustments (such as respiratory adjustments, for example) may help reestablish the requirements of a pressure-regulating system.

The physiology of the fetal heart differs significantly from that of the mature post-natal organ: e.g., the metabolic supply for adult cardiac contraction relies mainly on fatty acids; whereas, the fetal heart uses carbohydrates as its primary energy source. Limited morphological descriptions of the developing myocardium have appeared. However, additional studies are required to elucidate the ultrastructural changes occuring in the perinatal period when enormous physiological adjustments are made. Although adult animals are most often used in toxocological and pathological analyses, it is also important to investigate fetal cardiac responsiveness to various agents. The vulnerability of the ultrastructure of the fetal mouse myocardium to genetic and environmental assault is the subject of this report. The genetically determined effect on the heart was observed in mouse embryos homozygous for the cab (cardiac abnormality) mutation discovered by Essien.

Oral leukoplakia (OL) is a premalignant lesion described as “a predominant white lesion of the oral mucosa which cannot be defined as any other known lesion”. OL located on the floor of the mouth, soft palate and tongue are considered as high-risk lesions, while, in other areas, they may be considered as of low malignancy risk. A Forty five years old male patient had complaints of white lesion on left lat. Surface of tongue, along with burning sensation since 4-5 months. He was diagnosed with Leukoplakia and he had taken allopathic medicine for 4 to 5 times, but it was inversely relapsed, so he was treated with Pratisarana of Bibhitaka Churna and Rasayana Churna, Yastimadhu Ghanavati as lozenges along with Rasayana tablets orally for a period of 6 months. After 6 month therapy, white lesion became disappear and no burning sensation. Thus this patient was successfully treated with above therapy with no recurrence or any complications till date.

Smoke taint has become a prominent issue for the global wine industry as climate change continues to impact the length and extremity of fire seasons around the world. Although the issue has prompted a surge in research on the subject in recent years, no singular solution has yet been identified that is capable of maintaining the quality of wine made from smoke-affected grapes. In this review, we summarize the main research on smoke taint, the key discoveries, as well as the prevailing uncertainties. We also examine methods for mitigating smoke taint in the vineyard, in the winery, and post production. We assess the effectiveness of remediation methods (proposed and actual) based on available research. Our findings are in agreement with previous studies, suggesting that the most viable remedies for smoke taint are still the commercially available activated carbon fining and reverse osmosis treatments, but that the quality of the final treated wines is fundamentally dependent on the initial severity of the taint. In this review, suggestions for future studies are introduced for improving our understanding of methods that have thus far only been preliminarily investigated. We select regions that have already been subjected to severe wildfires, and therefore subjected to smoke taint (particularly Australia and California) as a case study to inform other wine-producing countries that will likely be impacted in the future and suggest specific data collection and policy implementation actions that should be taken, even in countries that have not yet been impacted by smoke taint. Ultimately, we streamline the available information on the topic of smoke taint, apply it to a global perspective that considers the various stakeholders involved, and provide a launching point for further research on the topic.

Many of the large number of underground works constructed or under construction in recent years are in unfavorable terrains facing unusual situations and construction conditions. This is the case of the subject under study in this paper: a tunnel excavated in evaporitic rocks that experienced significant karstification problems very quickly over time. As a result of this situation, the causes that may underlie this rapid karstification are investigated and a novel methodology is presented in civil engineering where the use of saturation indices for the different mineral specimens present has been crucial. The drainage of the rock massif of El Regajal (Madrid-Toledo, Spain, in the Madrid-Valencia high-speed train line) was studied and permitted the in-situ study of the hydrogeochemical evolution of water flow in the Miocene evaporitic materials of the Tajo Basin as a full-scale testing laboratory, that are conforms as a whole, a single aquifer. The work provides a novel methodology based on the calculation of activities through the hydrogeochemical study of water samples in different piezometers, estimating the saturation index of different saline materials and the dissolution capacity of the brine, which is surprisingly very high despite the high electrical conductivity. The circulating brine appears unsaturated with respect to thenardite, mirabilite, epsomite, glauberite, and halite. The alteration of the underground flow and the consequent renewal of the water of the aquifer by the infiltration water of rain and irrigation is the cause of the hydrogeochemical imbalance and the modification of the characteristics of the massif. These modifications include very important loss of material by dissolution, altering the resistance of the terrain and the increase of the porosity. Simultaneously, different expansive and recrystallization processes that decrease the porosity of the massif were identified in the present work. The hydrogeochemical study allows the evolution of these phenomena to be followed over time, and this, in turn, may facilitate the implementation of preventive works in civil engineering.

This article considers ways in which solidarity across social locations might play a role in fostering resistance to vulnerability. My case study consists of the interplay between writer George Ryga’s 1967 play The Ecstasy of Rita Joe, and Okanagan Syilx writer and scholar Jeannette Armstrong’s 1985 novel Slash. While these important and compelling texts have received considerable critical attention, the relationship between them is less known. I am interested in the ways in which these works both hail and offer critique to one another. In the contemporary moment, in which questions of appropriation of voice have gained renewed urgency within Indigenous literary circles in Canada and beyond, the relationship between these texts speaks to a historical instance of appropriation, but also of complicated processes of alliance-building. These texts demonstrate how agency resides across multiple locations. I read Ryga’s Ecstasy in the context of Jeannette Armstrong’s engagement with the play within her novel Slash in order to witness the ways in which Ryga’s text, in the first instance, appropriates Indigenous voices into an anti-capitalist critique. In the second instance, I read these works in order to witness how they might simultaneously provide a compelling analysis of the vulnerability of the people who are the subject of both works. I compare the interplay between Armstrong and Ryga’s texts to contemporary debates around appropriation in order to argue for the historical and ongoing importance of these two works as precursors to the crucial interventions made by contemporary Indigenous critics and writers.
