Type And Material of Fixed Prosthodontic Appliances in Patients Living in the Region of Metković

The aim of this study was to evaluate the type and the aesthetic material in relation to age, gender, level of education, employment, socio-economic status and frequency of visits to the dentist. The examination was performed on 212 patients who had a fixed prosthodontic appliance for more than a year (55% males and 45% females, age 18-80 yrs.). The following conclusions were made: 1. The older patients and retired patients had significantly more bridges than crowns (p0.05). Patients who visit their dentist regularly have significantly more crowns than bridges than patients who visit their dentist irregularly or when in pain (p0.05). 2. Almost all fixed prosthodontic appliances older than 10 years were made of porcelain (98%), while acrylic veneer crowns were more frequent in appliances older than 10 or 15 years (p0.05). Patients older than 60 years had more acrylic material compared to younger patients. While patients younger than 39 years had almost exclusively ceramic appliances (p<0.01). Less educated patients had more acrylic veneer appliances. Employed patients had significantly more ceramic appliances than retired patients

West Nile virus in the New World: potential impacts on bird species

The past five years have seen the arrival and extremely rapid expansion of West Nile virus (WNV) in the Western Hemisphere. The rapid sweep across North America has permitted little time for developing knowledge of the virus’s potential impacts on wildlife in the New World. Given this information gap, we here summarize for the ornithological community what is known or can be anticipated for WNV’s effect on bird communities in coming years. Our particular focus is on impacts of WNV on the conservation status of birds, the principal vertebrate reservoir for the virus

Analisa Laju Produksi Kritis Menggunakan Metode Chierici Dalam Evaluasi Terjadinya Water Coning Pada Sumur X Lapangan Y PT Pertamina Ep Asset 1field Ramba

Dengan terus meningkatnya kebutuhan akan minyak dan gas bumi memicu PT Pertamina EP Asset 1 Field Ramba yang bergerak di bidang industri minyak dan gas bumi untuk meningkatkan produksi minyak dan gas bumi. Salah satu langkah nyata yang diambil oleh PT Pertamina EP Asset 1 Field Ramba ialah menganalisa sumur produksi kenapa oil recovery nya menurun. Salah satu penyebab penurunan oil recovery disebabkan oleh tingginya kadar air. Ada beberapa faktor penurunan kadar air, salah satunya adalah terjadinya Water Coning.Water Coning adalah problem pergerakan air secara vertikal menyusup ke lapisan produktif. Problem ini dapat terjadi akibat Q actual melebihi Q kritis, sehingga penghisapan secara berlebihan mengakibatkan gradien tekanan alir melebihi gaya gravitasi sehingga terjadi penerobosan lapisan produktif oleh air. Gejala water coning ini dapat dilihat dari permukaan, yaitu terjadinya peningkatan kadar air yang significant diteruskan dengan analisa seberapa besar laju produksi kritisnya dengan metode chiericci dan dianalisis juga perkembangan coningnya. Dari data produksi Q actual pada sumur X-41 sebesar 87 Bopd, X-95 sebesar 131 Bopd, X-98 sebesar 189 Bopd, dan X-99 sebesar 148 Bopd. Hasil dari perhitungan laju produksi kritis menggunakan metode chierici untuk sumur X-41 adalah 0,42 Bopd, sumur X-95 sebesar 1,19 Bopd, sumur X-98 sebesar 18,36 Bopd, dan sumur X-99 sebesar 14,96 Bopd. Hal ini menyatakan bahwa ke empat sumur yang dikaji mengalami water coning karena Q actual dari keempat sumur ini jauh melebihi Q kritis nya.Kemudian dilakukan penentuan penanganan untuk masalah coning tersebut

Experimental infection of chickens as candidate sentinels for West Nile virus.

We evaluated the susceptibility, duration and intensity of viremia, and serologic responses of chickens to West Nile (WN) virus (WNV-NY99) infection by needle, mosquito, or oral inoculation. None of 21 infected chickens developed clinical disease, and all these developed neutralizing antibodies. Although viremias were detectable in all but one chicken, the magnitude (mean peak viremia <10,000 PFU/mL) was deemed insufficient to infect vector mosquitoes. WNV-NY99 was detected in cloacal and/or throat swabs from 13 of these chickens, and direct transmission of WNV-NY99 between chickens occurred once (in 16 trials), from a needle-inoculated bird. Nine chickens that ingested WNV-NY99 failed to become infected. The domestic chickens in this study were susceptible to WN virus infection, developed detectable antibodies, survived infection, and with one exception failed to infect cage mates. These are all considered positive attributes of a sentinel species for WN virus surveillance programs

Factors Associated with The Occurrence of Anemia in Pregnant Women At Kaubele Health Center, Biboki Moenleu District, North-Central Timor Regency

Anemia berdampak pada ibu hamil dan bayi, seperti meningkatkan risiko perdarahan saat melahirkan, meningkatkan angka bayi lahir dengan berat badan rendah (BBLR), kecacatan bahkan kematian bayi. Pada tahun 2020, ada 206 ibu hamil (82,3%) yang mengalami anemia dan berdampak pada kejadian BBLR di Puskesmas Kaubele. Tujuan dari penelitian ini adalah untuk mengetahui faktor-faktor yang berhubungan dengan kejadian anemia pada ibu hamil di Puskesmas Kaubele Kecamatan Biboki Moenleu Kabupaten Timor Tengah Utara. Penelitian ini merupakan penelitian survei analitik dengan metode Cross Sectional Study. Populasi adalah seluruh ibu hamil trimester II dan III yang tercatat di buku register KIA dan Gizi di Puskesmas Kaubele tahun 2021, sebanyak 105 orang. Sampel sebanyak 50 orang dengan menggunakan metode simple random sampling. Instrumen penelitian ini adalah kuesioner dan pemeriksaan Hb. Teknik analisis dalam penelitian adalah analisis uji chi square. Hasil analisis menunjukkan ada hubungan antara kunjungan ANC (p=0,000), pola konsumsi (p=0,018), kepatuhan mengkonsumsi tablet Fe (p=0.000), dengan kejadian anemia. Sedangkan penyakit infeksi tidak berhubungan dengan kejadian anemia (p=0,651). Saran kepada petugas kesehatan agar meningkatkan komunikasi dan penyuluhan kepada ibu hamil tentang pola konsumsi zat besi yang baik, melakukan pemantauan konsumsi tablet Fe pada ibu hamil serta melakukan pemantauan kunjungan ANC agar dilakukan upaya pencegahan anemia

Active tuning of high-Q dielectric metasurfaces

We demonstrate the active tuning of all-dielectric metasurfaces exhibiting high-quality factor (high-Q) resonances. The active control is provided by embedding the asymmetric silicon meta-atoms with liquid crystals, which allows the relative index of refraction to be controlled through heating. It is found that high quality factor resonances ($Q=270\pm30$) can be tuned over more than three resonance widths. Our results demonstrate the feasibility of using all-dielectric metasurfaces to construct tunable narrow-band filters.Comment: 4 pages, 6 figure

Distribution of Craniofacial Variables in South Dalmatian and Middle Croatian Populations

The objective of the present work was to determine some relevant craniofacial parameters, particularly in relation to sex, for the study of the distribution of basic head and face types, and to investigate craniofacial and morphological differences between two population samples. The study sample comprised 100 subjects of both sex aged 18 to 30 from South Dalmatia and 200 subjects from Middle Croatia. Eight basic craniofacial variables were measured to obtain head, forehead and face indexes. The data indicate that average values of all variables can be used as standard craniofacial parameters for the examined population groups. All the craniofacial variables are considerably higher in men than in women (p < 0.05). In the South Dalmatian population mesocephalia (48.0%) and leptoprosopia (82.0%) prevail, while in the Middle Croatian population the brachycephalia (62.0%), and euriprosopia (73.5%) are present to a greater degree. The most significant craniofacial and morphological differences between the examined study samples are head width (Eu–Eu), face width (Zy–Zy), and forehead height (Tr–N). They were found to be statistically significant in the examined Middle Croatian population (p < 0.05). The presented measurements are highly relevant to orthodontic diagnostics and therapy

Electromagnetic Energy for a Charged Kerr Black Hole in a Uniform Magnetic Field

With the Komar mass formula we calculate the electromagnetic energy for a charged Kerr black hole in a uniform magnetic field. We find that the total electromagnetic energy takes the minimum when the Kerr black hole possesses a non-zero net charge $Q = 2\xi B_0 J_H$ where $B_0$ is the strength of the magnetic field, $J_H$ is the angular momentum of the black hole, $\xi$ is a dimensionless parameter determined by the spin of the black hole.Comment: 9 pages, 1 figur
