    Climate change (CC) is widely accepted as the major threat of our time, posing unprecedented challenges to humanity. Yet very little is known regarding the ways in which upper-secondary curricula address the need to educate about this crisis. This study contributes to the field of CC education theoretically and empirically. From the theoretical perspective, the study contributes two CC conceptualisation frameworks: a characterisation of the nature of CC, and a mapping of the scope of CC content knowledge. The empirical contribution consists of examining CC education implementation within upper-secondary curriculum in the state of Victoria, Australia. Specifically we examined the CC conceptualisation and the scope of content present in the Victorian Certificate of Education (VCE) study designs. A total of 10 out of 94 study designs qualified for examination through referencing CC. The findings suggest that none of the study designs present a complete conceptualisation of the nature of CC. Common conceptualisations within the study designs perceive CC as a cause or an outcome, a problem of management, or of technological efficiency. CC content within the study designs is limited, and presents misconceptions, including the assumption that CC is a natural change caused by astronomical and solar systems. A cross-curriculum integration approach within the study designs is found to be ineffective. We conclude that CC presents a paradigm shift which brings about the new discipline of CC. There is a need for curricula reforms to address and incorporate CC as a coherent body of knowledge

    Background: One of the most common congenital malformations, with widespread racial and regional variation is an orofacial cleft. The occurrence is attributed to an array of environmental and genetic factors. Blood grouping and Rh factor are genetically determined. Any possible association of clefts with them helps in planning interventional services. Methods: A case control observational study was conducted on 111 samples who were cases presenting with oral clefts in Super speciality hospitals and other 111 samples who came to hospital for their treatment other than for cleft lip or cleft palate, were controls in the study. Cases were evaluated for various phenotypes of clefts. Blood samples of each case and control was collected to elaborate on blood group genotype and Rh typing. SPSS 22.0 version was employed for statistical analysis. Results: The most common blood group noted in cases as well in controls respectively was type ‘B’ in 31.5% and 43.2%, while blood group ‘AB’ was noted the lowest in both cases (14.5%) and controls (7.3%).Rh positive was noted 94.6% in both cases and control population. Clefts were observed more in male population than female counterparts.Cases of cleft lip and palate (CLP) was noted the highest, in 61 (55%) of cases, followed by defects in lip, palate and lastly in soft palate. Conclusions: Though not associated to the biological characteristics of cleft lip and palate in the current study, the functional importance of ABO blood group distribution may be the subject of future research. Identification of any associative traits for clefts assesses individuals with risk so as to help eliminate the chance of occurrence and early identification for better prognosis

    A 6-year 8-month-old girl presented with a moderate Class III malocclusion characterized by mid-face deficiency and an anterior cross bite. In the first phase, the patient was treated with combination of reverse twin block and facemask therapy. In phase two, fixed appliances were placed in the permanent dentition. The post treatment results were good and a favorable growth tendency could be observed. The correction of the Class III malocclusion occurred by a combination of skeletal and dental improvements. This report shows successful correction of skeletal Class III malocclusion in the early transitional dentition using combination therapy

    Multiple developmental dental anomalies in a nonsyndromic patient: A rare case report

    No full text
    The present case report illustrates a rare occurrence of multiple dental anomalies in a healthy 12-year-old patient including anomalies of shape and number of teeth. The developmental dental anomalies noticed in the present case scenario are dens invaginatus, taurodontism, radix entomolaris, supernumerary teeth, and pulp stones seen in multiple teeth. It is not rare to notice these anomalies individually, but their combination is rare in a single, non-syndromic patient. This report also signifies the importance of thorough extra-intra-oral and radiographic examinations of patients with dental anomalies

    Botulinum toxin type A (BTX-A) (Botox, Allergan, Irvine, CA, USA) has been studied since the late 1970s for the treatment of several conditions associated with excessive muscle contraction. Smile esthetics has become a major concern among patients and orthodontists. This article describes the efficient, nonsurgical, and less invasive use of BTX-A injection for the correction of a gummy smile in orthodontics

    Objective: To assess the validity of a questionnaire (consisting of 10 items/questions) to identify hearing loss (HL) among three-wheeler tempo and noncommercial car drivers. Materials and Methods: This was a cross-sectional study conducted in an urban area of Lucknow city. Three-wheeler tempo drivers and noncommercial car drivers were assessed for HL by audiometry. A total of 300 subjects, who fulfilled the study criteria, were selected for the interview and health assessment. The pure tone audiometry was conducted after >12 hours of the last noise exposure to avoid temporary threshold shift. Results: The percentage of respondents aged between 31 and 40 years was 36%. The highest affirmative response item was “Do you have trouble hearing in noisy background?” constituting 68% and the lowest affirmative response item was “Do you have trouble understanding the speech of women and children?” constituting 33.7%. Kappa values showed that there was significantly (<0.05) mild agreement between most of the items and the gold standard for mid and high-frequency HL. The area under the curve for low, mid, and high frequency HL was 0.76% (95% CI = 0.68–0.84), 0.69 (95% CI = 0.73–0.75), and 0.67 (95% CI = 0.62–0.73), respectively. The sensitivity and specificity were reasonable for all the definition of HL at different cutoff scores. Conclusion: A self-reported questionnaire-based approach may be used for the assessment of HL especially when audiometry is not feasible

    The sign language is important to people who are Mute or Deaf generally have hearing and speaking deficiency. It continues to be the preferred tool of communication among them. It is the well-structured code of hand gestures, where these gestures have the specific meaning, used to convey the information. The aim of this paper is to propose a system and methods for recognizing the different signs which are Indian Sign Language. The proposed system translates gestures into speech and text format. This system, in particular, is designed to convert Kannada sign language. We have designed and implemented a data glove, which includes a set of sensors and a Wi-Fi communication module with microcontroller ATMEGA2560. Hand sign is constructed, Classification into final text and speech transformation and follow interpretation. This system is portable, offering a neat translation of Kannada sign language on any android platforms on the connection. Thus, allowing someone with no knowledge of a Kannada sign language to be able to understand and interact

    Hydrometallurgical Production of Electrolytic Manganese Dioxide (EMD) from Furnace Fines

    The ferromanganese (FeMn) alloy is produced through the smelting-reduction of manganese ores in submerged arc furnaces. This process generates large amounts of furnace dust that is environmentally problematic for storage. Due to its fineness and high volatile content, this furnace dust cannot be recirculated through the process, either. Conventional MnO2 production requires the pre-reduction of low-grade ores at around 900 °C to convert the manganese oxides present in the ore into their respective acid-soluble forms; however, the furnace dust is a partly reduced by-product. In this study, a hydrometallurgical route is proposed to valorize the waste dust for the production of battery-grade MnO2. By using dextrin, a cheap organic reductant, the direct and complete dissolution of the manganese in the furnace dust is possible without any need for high-temperature pre-reduction. The leachate is then purified through pH adjustment followed by direct electrowinning for electrolytic manganese dioxide (EMD) production. An overall manganese recovery rate of >90% is achieved.info:eu-repo/semantics/publishe
