The article discusses the speech personality of Sheldon Lee Cooper in a communicative aspect. The aim of the article is to identify linguistic features of speech acts of Sheldon Lee Cooper. The subject matter of this research is the speech acts typology of Sheldon Lee Cooper’ utterances. Respectively, the object is locution of the utterances, indicating the speech personality of Sheldon Lee Cooper. The article utilizes the classification of speech personalities based on the level of communicative competence, where personality can belong to a strong, mediocre (average) or weak type. Determination of the type of Sheldon Lee Cooper includes the following parameters: creativity, level of text construction of any thematic and genre-stylistic design; mastery of all functional and stylistic varieties of literary language; expanded active vocabulary; combination of different elements of speech, adequate to the objectives of communication; fluency in both oral and written form of speech and unmistakable choice of speech form depending on communicative goals. Analysis of the lexical and grammatical layers of Sheldon Lee Cooper' speech gave grounds to classify the speech personality to a certain type (strong, mediocre (average) or weak). To achieve the aim, the following methods were used: descriptive and structural methods allow us to characterize the typological features of the classification based on level of communicative competence; contextual and speech act analysis were applied to identify the communicative intentions of Sheldon Lee Cooper’s utterances and his attitude to the conversation; the method of linguistic modeling helped to figure out the level of communicative competence of Sheldon Lee Cooper’s speech personality.

Freeman-Sheldon Syndrome is a well-defined rare congenital syndrome characterized with skeletal anomalies, joint contractures and typical facial appearance. Most of the cases of Freeman-Sheldon Syndrome are sporadic without family history. Etiology of this sydrome is inadequately understood. It affects the males and females equally. Early diagnosis and early successful surgical management is important to achive good results. Since almost one hundred cases have been reported in the literature uptoday, we want to present a case with Freeman- Sheldon Syndrome in this study.

We report a case of a male baby who has characteristic signs of Freeman–Sheldon syndrome, a rare but recognizable, severe autosomal dominant form of distal arthrogryposis. Diagnosis was based on the distinctive clinical characteristics of the syndrome and confirmed by genetic analysis that showed a de novo missense mutation c.2015G>A (p.Arg672His) of the MYH3 gene. We highlight the different features present in our patient and describe the etiology of the Freeman–Sheldon phenotype and how its clinical complications can be dealt with. To the best of our knowledge, this is the first molecularly confirmed case of Freeman–Sheldon syndrome in sub-Saharan Africa.

Resumo:

This article analyses whether and to what extent the popular TV show The Big Bang Theory conveys anti-intellectual ideas. The starting point of my enquiry is the verbal behaviour of the ‘main nerd’ of this series, Sheldon Cooper, who is noteworthy for his lack of empathy and propriety. I aim to shed light on the kind of inappropriate verbal behaviour Sheldon displays by analysing a speech pattern this character is particularly bad at ‐ ‘white lies’, that is lies made out of consideration for other people’s feelings. By drawing on Immanuel Kant’s thoughts on civility in his Anthropology from a Pragmatic Point of View (1798), I will detail the social implications of white lies and how Sheldon fails in employing them. Doing so will be helpful in establishing why Sheldon’s comments and behaviour appear as outlandish as they do. This in turn provides important insights into the way the televisual text of The Big Bang Theory relates with its audience and the social implications of this connection. I will conclude with the observation that the portrayal of Sheldon Cooper relies heavily on two kinds of stereotypes: anti-intellectual ones and those associated with the ‘nerd’ identity.

An experimental candelilla-shellac formulation for coating apples (Malus ×domestica Borkh.) was developed and compared with commercial shellac-based and carnauba-shellac-based coatings on `Gala' and `Delicious' apples by determining effects on quality attributes, respiration, and internal atmospheres. Fruit were stored at 5 °C for 7 days followed by storage at 21 °C for 14 days. Gloss of `Delicious' apples coated with candelilla-shellac formulations containing 7% to 34% shellac increased with increasing shellac concentrations. `Gala' and `Delicious' apples coated with a candelilla formulation containing 34% shellac maintained quality similar to those coated with commercial carnauba-shellac-based coatings, as indicated by gloss, firmness, internal CO2, O2 and ethanol levels, steady-state respiration rate, weight loss, and flavor. By comparison, shellac-coated fruit maintained the highest gloss throughout the experimental period. Shellac-coated apples were also firmer, contained more ethanol, and received higher flavor scores than did apples receiving other coating treatments. Gloss of all coated fruit decreased with time, although shellac-coated fruit lost less gloss over the 21-day storage period. Analysis of gloss, firmness, fruit respiration, ethanol, weight loss, and flavor demonstrate that the candelilla formulation containing 34% shellac is competitive with current commercial carnauba-based apple-coating products.

Purpose This research aims to compare the contributions of two authors and practitioners from the 1920s whose work was, to a certain extent, at odds with the dominant scientific management approach of the period. Design/methodology/approach In this paper, a comparative textual analysis of texts written by Sheldon and Follett in the 1920s has been performed. This technique consists of a hierarchical descendant classification, which we use to uncover the thematic universes that Sheldon and Follett create in characterizing the fundamentals of management activity. Findings This comparative textual analysis shows that Follett and Sheldon developed two different ways of relying on a singular fundamental principle of management: integration. Originality/value A comparative analysis of Follett and Sheldon’s work has never been attempted. While textual analysis has been used in management research, to the authors’ knowledge, such analyses are rare in research seeking to understand management history.

Many of you will know that Sheldon Green died suddenly, towards the end of 1995. When Ewine asked me to say a few words at this meeting, in Sheldon's memory, I thought it very appropriate to do so and did not hesitate to agree. Although several people here probably knew Sheldon personally better than I (because our careers evolved on opposite sides of the Atlantic), it is possible that no-one present is more familiar with his published work.

Undergraduate students benefit from a class exercise that examines the relationship between body builds and personality characteristics. Procedures were designed to allow students to confront biases about their own friends and acquaintances in the context of Sheldon's somatotypes (Sheldon and Stevens, 1940; Sheldon, Stevens and Tucker, 1942). Class discussion about this demonstration can incorporate a broad range of topic areas, including stereotyping, the history of personality theory, personality assessment techniques, the importance of research control and the limitations of correlational research.

This study was aimed at modifying local Shellac with citric acid in varied concentrations of 2, 4, 6, 8 and 10 % (w/w) to prepare Shellac-Bagasse (Sh-Bg) biocomposite and determining its physico-chemical properties. The biocomposite was made from the natural Shellac matrices and Bagasse fibers. Physico-chemical properties of non-modified Shellac and Shellac modified with citric acid including functional groups, intrinsic viscosity, density, and mechanical tensile strength were characterized using Fourier transform infrared spectrometer (FTIR), Oswald viscometer and Universal Testing Machine (UTM). The analysis results showed an optimum modification of shellac-citric acid at a concentration of 4% (w/w). FTIR analysis of the modified Shellac showed a broad absorption at 3448 cm–1 which indicated the presence of hydroxyl groups (-OH). The presence of C=O ester groups was indicated by the absorption appearing at 1712 cm–1. The absorption at 1251-1250 cm–1 indicated the presence of C-O groups, while the presence of -CH2 methylene groups was indicated by the absorption at 1465 cm–1. The modified Shellac with its optimal intrinsic viscosity of 169.97 mL/g indicated that there was a reaction between citric acid and Shellac to form an ester, so that the polymer chains formed were longer with a low density of 0,6662-0,8168 mg/L when compared to Shellac without modification. The low density indicated that the citric acid-modified Shellac could be processed to be biocomposite. The biocomposite was made with various compositions of Shellac and Bagasse with hot press at 80 °C and under a pressure of 6 Kgf/cm2. The optimum ratio of Shellac to Bagasse in Shellac-Bagasse (Sh-Bg) biocomposite was of 60:40 %. While, the analysis using Universal testing machine resulted a mechanical tensile strength of 0.6 MPa and an elongation at break of 0.45 %.

The objective of this study was to assess feasibility of applying shellac as a biopolymer filament for using in fused deposition modeling (FDM) 3D printing. The shellac matrices were prepared through hot melt process by heating the ground shellac samples at 80°C in a silicone oil bath under continuous stirring for 15 min. Accelerated stability testing (annealing process) was also performed in order to evaluated thermal stability by re-heating shellac matrices at 80 °C for 12 h and 24 h in a hot air oven. The shellac matrices and annealed shellac matrices were then comparatively characterized. In the present study, all shellac matrices were investigated for physical appearance, acid value, insoluble solid, moisture content and also characterized by instrument analysis including Fourier-transform infrared (FTIR) spectroscopy, powder X-ray diffractometry (PXRD) and thermal analysis. The results demonstrated that shellac with initial heat (80°C, 15 min) and annealed at 80°C for 12 h had similar properties except the annealed shellac at 80°C for 24 h which shown the lower acid value and formed insoluble solid. The melting temperature, decomposition temperature and melting enthalpy of shellac were around 63-64°C, over than 200°C and 23 J/g, respectively. Furthermore, the extruded filament based on shellac was achieved by hot melt extrusion (HME) technique. The findings revealed that the shellac properties might be suitable to fabricate FDM filaments.

With increased awareness about the environment, raw materials from petroleum based synthetics and the "green" quotient of consumer products have developed, shellac or shellac modified resins have gained importance due to their unique nontoxic and hypoallergenic properties. Shellac is water soluble, biologically degradable and has film forming, excellent adhesion, hardness, high gloss and superior in electrical properties. Shellac or shellac modified resins are also compatible with other resins and can be cross linked making them a wider applications. Shellac is abundant in Thailand, China and India, which produced from lac insects, Laccifer Lacca. The resinous secretion can be purified to become shellac. The main structure of shellac consists of polyesters and single esters that have hydroxyl and carboxyl groups [1, . Shellac was first used as a wood polish for music instruments and furniture and later for uses in spar varnishes with antifouling properties for ship paints, phonographic records, wood and wallpaper paints, printing inks, resins for electrical applications and floor polishes. Currently, new applications for using are such as child-safe paints and inks and the coating of fruits and vegetables, food and confectionary, pills, tablets and vitamins in the pharmaceutical industries. Bleached shellac has been widely used in pharmaceutical and cosmetics instead of native shellac due to the whiteness. However, conventional method for bleached shellac used many solvents [3, . Therefore, the aim of this study was to explore a new technique in order to avoid the use of organic solvent prior to the process of bleaching. The comparison was made between bleaching by the conventional and the new methods. The studied properties were acid value, viscosity, color change, water vapor permeability, chemical structure and powder x-ray diffraction.

Shellac is a natural product which has been presumed as a fragile polymer due to itschemical properties. The objective of this study was to improve chemical properties of shellac by themodification with different concentration of glycerol and acrylic acid. Shellac was reacted withglycerol at various temperature and amounts of glycerol. The intermediate product was reacted withacrylic acid at different concentration. Acid value, hydroxyl groups, and free glycerol concentrationof modified shellac was determined. The result showed that acid value gradually decrease alongincreasing temperature for each ratio of glycerol and acrylic acid to shellac. The concentration ofhydroxyl groups rise as temperature and ratio increases. Furthermore, free glycerol concentration felldown along with the rise temperature. Modification chemical properties of shellac with glycerol andacrylic acid can be applied for the further study to enhance shellac properties.

Kesambi (Schleichera oleosa (Lour.) Merr.) is a host plant that becomes priority in lac culture in Indonesia. Shellac is one of the non-timber forest product commodities, which is potential to be one of foreign exchange sources. World demand of shellac is increasing throughout the year so that the improvement of shellac productivity is required to fulfill the demand. One of the alternatives is implementing the fertilization due to host plant quality improvement considering that host plant is the source of nutrient of shellac. The activity of fertilization aims to understand the effect of fertilization dosage to the improvement of the branch length as well as productivity of shellac in KPH Probolinggo. The greatest average value of branch length during three and six months, respectively were 66.48 cm and 83.24 cm. While, the greatest average value of shellac productivity was 84.29 g. The treatment of fertilization in different dosage to the kesambi (Schleichera oleosa (Lour.) Merr.) was not give significant effect to the length of branch as well as shellac productivity.

Electrospun shellac nanofibers might be potentially used for wound dressing application due to its natural origin and excellent protective properties. In this study, a full factorial design with three replicated center points was performed in order to investigate the main and interaction effects of shellac content (35-40% w/w), applied voltage (9-27 kV) and flow rate (0.4-1.2 mL/hr) on the morphology of shellac nanofibers. A total of 11 experiments were conducted. The response variables were the diameter of nanofibers, the distribution of diameter and the amount of beads. The results showed that the concentration of shellac was the most significant impact on shellac nanofiber diameter, while applied voltage, interaction between shellac content and voltage, and feed rate were minor factors, respectively. Shellac content and applied voltage had negative relationships with bead amount. When reducing the concentration of shellac and voltage, the amount of beads was increased. However, the influence of these parameters on diameter distribution seemed to be not significant. Based on response surface plot, nanofibers with thinner diameter (~493 nm) and less number of beads (~0.47) could be obtained at the optimum conditions; the shellac content of 38.5% w/w, the voltage of 21 kV and the feed rate of 0.4 mL/hr.

Dimensional stability proves to be an important factor affecting the quality of wooden products. As a sort of crude and thermoplastic resin, shellac excreted by lac insects demonstrates water-repellent and environmental-friendly features. The research impregnated shellac with wood at room temperature and with a vacuum-pressure procedure. Efforts were made to examine how shellac treatment affected the dimensional stability, moisture absorption, chemical structure, thermostability, as well as morphological characteristics of wood. Results indicated that shellac treatment was a type of efficient solution useful in the enhancement of the dimensional stability of wood. Shellac solution had good permeability in the wood, and the weight percentage gain reached 13.01% after impregnation. The swelling coefficients of treated wood in the tangential and radial directions decreased by 20.13% and 24.12%, respectively, indicating that impregnation could improve wood dimensional stability. The moisture absorption of shellac-treated wood was reduced by 38.15% under 20 °C and 65% relative humidity. Moreover, shellac treatment significantly modified wood structure, although there were no drastic changes in the spectra. Specimens for shellac treatment ran across two decomposition peaks at 350 and 390 °C, and specimens in the control group saw one more common derivative thermogravimetric curve when the sharp peak approached 355 °C. After impregnation of shellac into wood, the shellac blocked pits and hardened on the intrinsic layer of the wood for fear of hygroscopicity. The practice was applicable to a variety of wood products, such as buildings, furniture, and landscape architecture.

Resumo:

This study reports some unexplored features of naturally occurring Indian shellac present in a typical truck tyre sidewall compound, at low doses with the intention of replacing stearic acid in the formula. The chemical characterization of shellac was determined using Fourier transform infrared (FTIR) spectroscopy, along with information from earlier published reports, revealing the presence of different fatty acids, alcohols, esters and quinone-based dyes. The substitution of stearic acid with shellac shows that 50% replacement of the acid with shellac obtained comparable rheometric and physical properties with the control compound. The presence of different components in shellac further helped to improve ageing and reversion resistance. The volatile loss from shellac is much lower compared with commercial stearic acid. Some essential properties for sidewall application such as extrudate shrinkage and die swell behaviour were also found to be suitable when 50% of the commercial stearic acid was replaced with shellac in the formula.

The aim of this study was to investigate the effect of electrospinning process on the physical properties of fibers made from shellac. Electrospun shellac fiber was prepared by dissolving shellac in ethanol and then transferred to the electrospinning system. The influences of process parameters; including electric field voltage, tip to collector gap, feeding rate and concentration of shellac solutions; on the spinnability and properties of obtained shellac fibers were elucidated. The result demonstrated that micro-nano fibers of shellac were easily formed after spinning. The concentration of shellac solution was a crucial parameter that determined the spinnability. The electro-sprayed particles of shellac were achieved at the concentration of 35% w/w and lower while the electrospun fibers was formed in the concentration range of 40-45 % w/w. SEM pictures demonstrated that the beaded fiber structure obtained at 40-43% w/w was changed to the continuous fiber structure at 45% w/w. The diameter of fiber showed a tendency to increase while the size distribution of diameter was narrower as increasing voltage. The other optimized electrospinning parameters including feeding rate, tip to collector gap were 0.5-2 ml/h and 15-20 cm, respectively. In conclusion, the study demonstrated the critical parameters that determined the properties of required fibers. The knowledge gained should support the development of the drug incorporated electrospun shellac fiber in near future.

Resumo:

Particulate matter (PM), composed of tiny solids and liquid droplets in polluted air, poses a serious threat to human health. Traditional air filters usually cause secondary pollution due to their poor degradability. Here, shellac, as an environmentally friendly natural organic material, was successfully applied to fabricate biodegradable air filters. Since pure shellac fiber shows poor mechanical properties and bad light transmittance, we then introduced a small amount of polyvinylpyrrolidone (PVP) in the shellac solution to prepare highly efficient air filter membranes by the electrospinning method. The prepared PVP-assisted shellac nanofiber membrane (P-Shellac FME) demonstrated improved filtration efficiencies as high as 95% and 98% for PM2.5 and PM10, respectively. The P-Shellac FME also showed good stability, with filtration efficiencies still above 90% and 95% for PM2.5 and PM10 even after six hours of air filtering under high PM concentrations. The pressure drop going through the filter was only 101 Pa, which is also comparable to the value of 76 Pa obtained using commercial polypropylene nanofibers (PP nanofibers, peeled off from the surgical mask), indicating good air permeability of P-Shellac FME. Additionally, P-Shellac FME also showed the advantages of translucence, biodegradability, improved mechanical properties, and low cost. We believe that the P-Shellac FME will make a significant contribution in the application of air filtration.
