Face and Neck Lifts: Smas Vectors for Support and Smile Crease Correction
No full text BF Connell. Face and neck lifts: SMAS vectors for support and smile crease correction. Can J Plast Surg 1993;l(2):75-82. The plastic surgeon undertaking face and neck lifts needs a precise vision of the end result, a specific anatomical diagnosis and a precise plan of repair. Using concepts which have evolved over the years, techniques can be applied to treat patients of all ages for rejuvenation and re-entry into the job market. </jats:p
Ega
No full textConnell B, Ahoua F, Gibbon D. Ega. Journal of the International Phonetic Association. 2002;32(1):99-104.
Ega is an endangered language spoken in the south-central region of Côte d'Ivoire, in Divo Department. The precise number of speakers is not known at present; the 14th
Ethnologue
(Grimes 2000) reports 291 to 3,000, and notes that ‘the ethnic group is growing, but they are shifting to the Dida language because of intermarriage and other influences’. Our own preliminary and impressionistic work suggests the number of Ega speakers to be closer to the upper end of this range, perhaps around 2,000, but we note that Ega now serves a decreasing number of sociolinguistic functions, to the extent that in at least some villages Dida has replaced Ega as the primary language of daily use. It is also clear that the degree of intergenerational transmission is low in many, if not all, Ega villages.

Descensus Christi ad Inferos: Christ’s Descent to the Dead
No full textThe narrative of Christ’s descent was nearly omnipresent in the early Church. Yet a change of Latin vocabulary from “descensus ad inferos” (Christ’s descent to the dead) to “descensus ad inferna” (Christ’s descent into hell) prompted a change in what was proclaimed. The earlier stratum portrayed Christ preaching to those who, while on earth, did not hear the word of God, while the latter described the reconciliation of sinners. The author here considers the vitality of this creedal statement and what is lost when the descent is absent from Christian experience
Recovery of a subtidal soft-sediment macroinvertebrate assemblage following experimentally induced effects of a harmful algal bloom
No full textA defaunation experiment mimicking the effects of a harmful algal bloom (HAB) on benthic macroinvertebrate assemblages (>500 µm) was conducted at a hydrodynamically active soft-substrate site in Wellington Harbour, New Zealand, to test the recovery rate (return to pre-disturbance state) of temperate benthic macroinvertebrate assemblages and to elucidate the main factors influencing the recovery process. Tarpaulins were used to create anoxic conditions by smothering the sediment for 65 d. Assemblage recovery in treatment plots was studied for 1 yr and compared with assemblage composition in undisturbed adjacent control plots. Recovery was slow until Day 70, at which time abundance of individuals (N) and number of species (S) increased synchronously in treatments and controls. Within 10 mo, univariate indices (N, S and also species diversity H’ and evenness J’) of treatment assemblages returned to values observed for the control assemblages. Multivariate analyses showed that fluctuations in assemblage composition were most pronounced in the first 100 d in treatment replicates, but decreased thereafter as the recovering assemblage became more similar to the undisturbed one. However, after 1 yr, even though the composition of treatment and control assemblages was converging, differences in composition were still significant. Based on the observed trajectory of recovery, complete assemblage recovery is predicted to take approximately 2 yr. Timing of the disturbance in relation to seasonal recruitment events was identified as an important factor for assemblage recovery
Position and Spin Operators, Wigner Rotation and the Origin of Hidden Momentum Forces
No full textAbstract. Using a position operator obtained for spin 1 2 particles by the present author and Wigner, we obtain a quantum relativistic result for the hidden momentum force experienced by particles with structure. In particular, our result applies to the hidden magnetic forces manifest in some problems of electromagnetism. We also discuss spin and orbital angular momentum operators, as well as Wigner rotation
High-prevalence and high-estimated incidence of HIV infection among new injecting drug users in Estonia: need for large scale prevention programs.
No full textOBJECTIVE: To examine HIV risk behavior and HIV infection among new injectors in Tallinn, Estonia. Design and methods Data from two cross-sectional surveys of injecting drug users (IDUs) recruited from a syringe exchange program (N = 162, Study 1) or using respondent driven sampling (N = 350, Study 2). Behavioral surveys were administered; serum samples were collected for HIV testing. Subjects were categorized into new injectors (injecting 3 years). RESULTS: Twenty-eight of 161 (17%, Study 1) and 73/350 (21%, Study 2) of the study subjects were new injectors. HIV infection was substantial among the newer injectors: HIV prevalence was 50% (Study 1) and 34% (Study 2), and estimated HIV incidence 31/100 PY and 21/100 PY, respectively. In Study 2, new injectors were more likely to be female and ethnic Estonian and less likely to be injecting daily compared with long-term injectors. No significant difference was found among two groups on sharing injecting equipment or reported number of sexual partners. CONCLUSIONS: A continuing HIV epidemic among new injectors is of critical public health concern. Interventions to prevent initiation into injecting drug use and scaling up HIV prevention programs for IDUs in Estonia are of utmost importance
Analysis of the Effects of Subcutaneous Musculoaponeurotic System Facial Support On the Nasolabial Crease
No full text The idea that traction on the subcutaneous musculoaponeurotic system (SMAS) deepens the nasolabial crease has been propagated through the plastic surgery literature. This notion is contrary to the senior author's experience. The purpose of the present study was to investigate the effects of mobilization of the SMAS on the nasolabial fold and crease. Intraoperative examination on the effect of traction on the SMAS was performed. Ten consecutive primary facelift patients underwent facelift procedures with SMAS support. Following mobilization of the SMAS, traction was placed on the SMAS without traction on the skin. In all cases, the nasolabial fold was effaced and the nasolabial crease did not deepen. The authors concluded that traction on the SMAS did not deepen the nasolabial crease. </jats:p
