Ada hubungan antara status kalkulus indeks dengan kepercayaan diri pada SMAN 2 Konawe Selatan &nbsp, Background: Calculus refers to the formation of mineral deposits that occur due to food remnants adhering to poorly cleaned dental plaque. This condition can lead to various dental problems. Calculus typically develops in hard-to-reach areas of the teeth, which are challenging to clean effectively. The research objective is to investigate the correlation between calculus index status and self-confidence among 11th-grade students at SMAN 2 Konawe Selatan. Research Method: This study employed an analytic observational method with a Cross-Sectional design. The sampling technique utilized simple random sampling, with a total sample size of 158 students. Data analysis was performed using Kendall's tau test with a significance level of a = 0.05. Research Results: The findings of this research revealed that the majority of respondents were females, accounting for 59.6% based on gender. Regarding age, the majority of respondents were 16 years old, constituting 63.9%. In terms of calculus index status, the majority fell into the moderate category, amounting to 60.1%. The Kendall's tau statistical test yielded a p-value of 0.000, which is less than 0.05. Conclusion: The study concludes that there is a correlation between calculus index status and self-confidence at SMAN 2 Konawe Selatan. &nbsp

Evidence about the dietary habits of the 42 individuals recovered in the necropolis of Boccone del Povero (1st-2nd century CE; Rome, Italy) was obtained by a multidisciplinary approach. Dental calculus analysis (through optical microscopy and gas chromatography-mass spectrometry) and stable isotope investigation from bone proteins were carried out on the human skeletal series, with a particular focus on the young female unearthed from the richest burial (no. CLXXXI) of the archaeological site. Overall, carbon and nitrogen stable isotope data indicated an omnivorous diet mainly based on C3-terrestrial proteins, although for some individuals C4 plant consumption cannot be excluded. In fact, evidence from calculus suggests the use of Andropogoneae (e.g., sorghum), Triticeae, together with Rosaceae seeds (e.g., almonds), milk and dairy products. The application of morphological, biochemical, and biomolecular techniques provided a reconstruction of the subsistence pattern of this ancient population living in a suburb of the Imperial Rome.

Background: Despite the fact that Helicobacter spp. has been detected in equine gastric mucosa, no evidence exists about this infection in Colombian horses affected by equine ulcerative gastric syndrome (EGUS), nor in dental tartar. Objective: To detect Helicobacter spp. DNA in equine gastric mucosa and dental tartar and determine the relationship between the presence of Helicobacter spp. and gastric lesions. Methods: Samples of glandular gastric mucosa and dental tartar were collected from 30 equine slaughterhouses. Macroscopic lesions of the stomachs were classified and the total DNA in all samples was extracted using a commercial extraction kit. A final-point PCR was performed using primers for amplification of a segment of 251 bp of the gene encoding the 16s rRNA region; the amplified fragments were subjected to a second PCR to determine the presence of H. pylori, the VacA gene was typified. The resulting amplicons were sequenced. Results: It was possible to amplify 16s rRNA in several samples but there was no amplification of VacA. Fragments of the sequences were compatible with H. heilmannii. The 23.3 and 10% of gastric and tartar samples were positive for 16s rRNA of Helicobacter spp., respectively. Conclusion: Although genetic material of Helicobacter spp. was found in some animals, there was no relationship with gastric lesions. It is possible that helicobacteriosis has no bearing in EGUS etiology., Antecedentes: Apesar do Helicobacter spp. ter sido detectado na mucosa gástrica de equinos, não há evidências dessa infecção em cavalos crioulos colombianos afetados pela síndrome ulcerativa gástrica (SUGE), ou no sarro. Objetivo: Detectar ADN de Helicobacter spp. na mucosa gástrica e do sarro dental de equinos, e determinar a relação entre a presença de Helicobacter spp. e lesões gástricas. Métodos: Amostras de mucosa gástrica glandular e sarro dental foram coletadas de 30 equinos de abatedouro, as lesões macroscópicas dos estômagos foram classificadas. Se realizou extração de ADN total em todas as amostras através de kit comercial. Realizou-se PCR ponto final, amplificando o segmento de 251 pb do gene que codifica para a região 16s ARNr; os fragmentos amplificados foram sometidos novamente a PCR para determinar a presença de H. pylori, ao tipificar o gene VacA, e seguidamente foram sequenciados. Resultados: O houve amplificação do 16s ARNr em várias amostras, mas não amplificação de VacA. Fragmentos das sequencias foram compatíveis com H. heilmannii. O 23,3 e 10% das amostras gástricas e do sarro foram positivas para 16s ARNr de Helicobacter, respectivamente. Conclusão: Embora material genético de Helicobacter spp. encontrou-se em algumos animais não houve relação com lesões gástricas. Possivelmente a helicobacterioses não tem papel relevante na etiologia da SUGE., Antecedentes: A pesar de que se ha detectado Helicobacter spp. en mucosa gástrica equina, no existe evidencia de esta infección en caballos criollos colombianos afectados por síndrome ulcerativo gástrico (SUGE), ni tampoco reportes en sarro dental. Objetivo: Detectar ADN de Helicobacter spp. en sarro dental y mucosa gástrica de equinos, y determinar la relación entre la presencia de la bacteria y lesiones gástricas. Métodos: Las muestras de mucosa glandular gástrica y sarro dental fueron colectadas de 30 equinos que se encontraban en planta de beneficio. Las lesiones macroscópicas fueron clasificadas y el ADN total de las muestras fue extraído utilizando un kit comercial. Se desarrolló PCR convencional usando cebadores específicos para la amplificación de un segmento de 251 pb de un gen que codifica la región 16S del ARNr; los fragmentos amplificados fueron sometidos a una segunda PCR para determinar la presencia de H. pylori mediante la amplificación del gen VacA. Los amplificados resultantes fueron secuenciados. Resultados: Fue posible amplificar 16s ARNr en varias muestras, pero no hubo amplificación de VacA. Los fragmentos de las secuencias fueron compatibles con H. heilmannii. El 23,3 y 10% de las muestras gástricas y sarro fueron positivas para 16s ARNr de Helicobacter spp., respectivamente. Conclusión: Aunque el material genético de Helicobacter spp. se encontró en algunos animales, no hubo relación con las lesiones gástricas. Es posible que la helicobacteriosis no tenga incidencia en la etiología del EGUS.

The U.S. Army Transportation Engineering Agency, Military Traffic Management and Terminal Service participated in the monitoring of a highway shipment of 18 ready-for-issue missiles with the Naval Weapons Handling Laboratory, Naval Ammunition Depot, Earle, Colts Neck, New Jersey. The missiles, consisting of TARTARS, TERRIERS, and STANDARDS in MK 199 and MK 372 containers, were transported from the Naval Weapons Station (NWS), Charleston, South Carolina, to the Naval Weapons Station (NWS), Concord, California, via Oklahoma City, Oklahoma, between 18 April and 23 April 1970. Environmental factors monitored consisted of shock and vibration and road conditions and temperature, relative humidity, and pressure. The transport vehicle was a standard suspension semitrailer pulled by an over-the-road tractor. (Author)

The report covers an analysis of the system problems arising from the conversion of Tartar, Terrier, and Standard missile telemetry from VHF to UHF and provides recommendations on how this conversion can be accomplished. These recommendations are based on minimizing the amount of system redesign by using as many major components of the existing system as is possible, consistent with the economic and performance requirements. The study is based on a fundamental analysis of the RF system links and includes those parameters which affect the performance of the cooperative doppler scoring subsystem. The doppler scoring subsystem shares one missile transmitter and antenna subsystem with the telemetry system and also includes a target subsystem and certain portions of the Shipboard Telemetry subsystem.
