Heat-polymerized acrylic resins is the most used denture base material in prosthodontics. One of mechanical properties of acrylic resins is transverse strength. It represents the masticatory pressure that is applied to denture base. Black tea is the second largest consumed beverage in the world. The aim of this study was to investigate the effect of black tea beverage on transverse strength of heat-polymerized acrylic resins. A total of 24 heat-polymerized acrylic resin plates (65×10×2,5 mm) were immersed in black tea beverage for 1, 4, and 20 days as treatment group and in aquadest for 1, 4, and 20 days as control group. The transverse strength of acrylic samples were measured by three–point bending test by universal testing machine. Data were statistically analyzed using Independent t test. The transverse strength values of acrylic resin immersed in black tea beverage had no significant differences to the transverse strength values of acrylic resin immersed in aquadest with similar immersion time (p>0,05). There was no effect of black tea beverage on transverse strength of heat-polymerized acrylic resins. Immersion time decrease the transverse strength of heat-polymerized acrylic resins due to water sorption.

Forensic odontology in dentistry is used to identify victims. Several methods can be used, such as rugoscopy.
Rugoscopy is a victim identification method by evaluating the palatal rugae. Rugoscopy is very advantageous due to its low cost, fast results and practical nature. Palatal rugae is protected from trauma and high temperature due to its internal position in the oral cavity. Palatal rugae is an individualistic structure, though it bears several resemblance with the hereditary pattern due to the polygenic mechanism. The purpose of this research is to determine the difference of palatal rugae shape and size between uncle and nephew in Minangkabau ethnics. This study is an analytical observational study with a cross sectional approach. A total of 78 pairs of uncle and nephew of the Minangkabau ethnicity in Luhak Nan Tigo. Palatal rugae is classified using the Thomaz and Khutze classification. Data were analyzed by using Mann Whitney non-parametric statistical analysis. Data analysis show the palatal rugae shape of uncle and nephew from the Minangkabau ethnicity is dominated by a wavy shape, followed by curvy, straight, unified and circular shapes. The palatal rugae size of uncle and naphew from the Minangkabau ethnicity is dominated by primary size, followed by secondary and fragmenter size. Mann Whitney analysis revealed no significant difference of palatal rugae shape and size between uncle and nephew in Minangkabau ethnics (p>0,05), though there is a significant difference in the unified shape (p<0,05). Palatal rugae shape and size have a similar pattern with hereditery patterns, though not identical. Palatal rugae may be used as a secondary method of victim identification

Palatal rugae or plica palatinae transversae are irregular and asymmetrical ridges on mucosa membrane which extend laterally from incisive papilla and anterior of palatal raphe. Palatal rugae are protected by cheeks, lips, tongue and buccal pad from incineration and trauma. The use of palatal rugae as an alternative way to identify human is needed in many occurrences such as accident, criminal and disaster. Palatal rugae patterns are vary and not identical in each person but have some similarities within family. This can be caused by hereditary and polygenic inheritance mechanism of palatal rugae. This study aimed to identify palatal rugae pattern similarities between father and his biological son in Minangkabau ethnic. This study is a cross-sectional study. The samples used in this study were 78 pairs of fathers and their biological sons. Alginate impression material was used to record the upper jaw. The impressions were casted by type III dental stone . Palatal rugae were marked and the amount of rugae based on their shape and length classifications were recorded. The data were analyzed using Mann -Whitney test. Result showed that there was no significant difference between fathers’ and their biological sons’ palatal rugae amount based on their shape (p>0,05), but there was significant difference between the amount of primary rugae of fathers and their biological sons (p<0,05). The conclusion is there are no significant differences between fathers’ and th eir biological sons’ palatal rugae amount based on their shape. Palatal rugae pattern can be used as an alternative in human identification because of its individual characteristic and uniqueness.

In popular literature, chicklit is one of the genres that focuses on the women's issues. For some scholars chicklit has a simple formula. In cultural studies, chicklit enriches various discourses especially the discourse of feminism.In this paper, analyzed about the construction of men in "The Hopeless Romantic's Handbook" by Gemma Townley's (2008) and "Cintapucinno" by Icha Rahmanti (2007). The construction of identity (men/women) is an important object in study of feminist discourse. The results of the study show that heroines construct ideal men’s standards. In gender discourse, the construction of men’s physical appearance and their symbol are considered as an activity or value equivalent as well as men constructs the identity and stereotypes of women through their bodies

Studies on pneumococcal resistome and molecular antimicrobial resistance mechanisms are relevant and may be used in large-scale epidemiological researches and surveillance of antimicrobial resistance.A study of antimicrobial molecular resistance in the pneumococcal strains, that were isolated from the patients having the different forms of the pneumococcal infection or carriage, and association of it with phenotypes, clinical and epidemiological features of the strains (serotype, form of the infection).We studied 546 pneumococcal strains and 5 specimens, that were isolated/obtained from the patients of various age (5 days – 81 years) having the different forms of the pneumococcal infection (meningitis and other invasive forms – 28, pneumonia – 27, acute rhinosinusitis – 18, acute otitis media – 118, conjunctivitis – 26) or carriage (331).We used multiplex PCR to detect the following molecular pneumococcal antimicrobial resistance determinants – genes mefA, ermB and mutations in the penicillin-binding proteins: pbp1a (574T→N, 575S→T, 576Q→G and 577F→Y); pbp2b (431T→K, 432Q→L) and pbp2x (338T→A).Among studied strains 60 % of 551 possess at least one resistance mechanism to macrolides/lincosamides, while 22 % were heteroresistant (mefA + ermB). About 65 % of the strains carry at least one pbp modification, 26 % – two modifications and 24 % – three pbp modifications. 23S RNA methylase (ermB gene) were discovered as a dominating mechanism and was detected in 43 % of genetically resistant strains. Pbp 1a + 2x + 2b and pbp 1a + 2x were more frequent modifications among penicillin genetically resistant pneumococci, while pbp2b genotype was not detected.
