In vitro evaluation of conventional and locking miniplate/screw systems for the treatment of mandibular angle fractures

This in vitro study evaluated the influence of the type of miniplate and the number of screws installed in the proximal and distal segments on the stability and resistance of Champy's osteosynthesis in mandibular angle fractures. Sixty polyurethane hemimandibles with bone-like consistency were randomly assigned to four groups (n = 15) and sectioned in the mandibular angle region to simulate fracture. The bone segments were fixed by different osteosynthesis methods using 2.0 mm miniplates and 2.0 mm x 6 mm rnonocortical screws. In groups 1 and 2, two conventional (G1) or locking (G2) screws were installed in each bone segment using a conventional (G1) or a locking (02) straight miniplate; in groups 3 and 4, three conventional (03) or locking (04) screws were installed in the proximal segment and four conventional (G3) or locking (04) screws were installed in the distal segment using a conventional (G3) or a locking (G4) seven-hole straight miniplate. The hemimandibles were loaded in compressive strength until a 4 mm displacement occurred between the segments, vertically or horizontally. Locking plate/screw systems provided significantly greater resistance to displacement than conventional ones (p < .01). Locking miniplates offered more resistance than conventional miniplates. Long locking miniplates provided greater stability than short ones.

In Vitro Biomechanical Evaluation of the Use of Conventional and Locking Miniplate/Screw Systems for Sagittal Split Ramus Osteotomy

Purpose: The aim of this in vitro study was to assess the biomechanical stability of 9 different osteosynthesis methods after sagittal split ramus osteotomy by simulating the masticatory forces and using a 3-point biomechanical test method.Materials and Methods: Forty-five polyurethane hemimandibles with bone-like consistency were randomly assigned to 9 groups (n = 5) and subjected to sagittal split ramus osteotomy. After 4-mm advancement of the distal segment, the bone segments were fixed by different osteosynthesis methods using 2.0-mm miniplate/screw systems: group A, one 4-hole conventional straight miniplate; group B, one 4-hole locking straight miniplate; group C, one 4-hole conventional miniplate and one bicortical screw; group D, one 4-hole locking miniplate and 1 bicortical screw; group E, one 6-hole conventional straight miniplate; group F, one 6-hole locking straight miniplate; group (3: two 4-hole conventional straight miniplates; group H. two 4-hole locking straight miniplates; and group 1, 3 bicortical screws in an inverted-L. pattern. All models were mounted on a base especially constructed for this purpose. Using a 3-point biomechanical test model, the hemimandibles were loaded in compressive strength in an Instron machine (Norwood, MA) until a 3-mm displacement occurred between segments vertically or horizontally. Data were analyzed by analysis of variance and Tukey test (alpha = 1%).Results: The multiparametric comparison of the groups showed a statistically significant difference (P<.01) between groups that used 2 miniplates (groups G and H), 1 miniplate and 1 bicortical screw (groups C and D), and only bicortical screws (group D compared with groups that used only 1 miniplate with 2 screws per segment (groups A and B) and 3 screws per segment (groups E and F).Conclusion: The placement of 2.0-mm-diameter bicortical screws in the retromolar region, associated or not with conventional and locking miniplates with monocortical screws, promoted a better stabilization of bone segments. Locking miniplates presented a better performance in bone fixation in all groups. (C) 2010 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 68:724-730, 2010

Oviympäristön hallinnan kehittäminen ovitoimittajan ja turvaurakoitsijan yhteistyönä

Työn tavoitteena oli selvittää yhteistyön ja verkostoitumisen mahdollisuuksia ovitoimittajan ja turvaurakoitsijan yhteistyönä pyrkien minimoimaan (uudis)rakennuksen oviympäristöön tapahtuvissa toimituksessa eri suunnittelijoiden suunnittelueriäväisyyksistä johtuvia lisätöitä, kustannuksia ja sähläystä eri toimijoiden kesken. Keskeisenä tavoitteena oli saada malli toimivan ovi-turvallisuusympäristön perustaksi. Lisäksi haettiin turvaurakoitsijalle, ovitoimittajalle ja rakennusliikkeelle suosituksia yhteistyön ja yhteistoiminnan edistämiseksi. Eri osapuolten näkemyksiä ja ongelmakohtia haettiin haastattelujen avulla. Tutkimuksesta kävi selkeästi ilmi ettei kukaan varsinaisesti koordinoi oviympäristön suunnittelua kokonaisuutena. Samanaikaisesti rakennusliike on hakenut halvinta hintaa joka nippelille, mikä taas on johtanut urakoiden pirstoutumiseen ja vaikeuttanut tilannetta entisestään. Toimenpide-ehdotuksena esitetään uutta liiketoimintamallia oviympäristön hallintaan. Mallin avulla on mahdollista saada aikaan säästöjä ja vähentää eri toimijoiden sähläyksestä aiheutuvia lisätöitä kuitenkin loppukäyttäjän tarpeet huomioiden. Lisäksi esitetään toimenpide-suosituksia yllä mainittujen toimittajien yhteistyölle.

Study of criteria influencing the success rate of DNA swabs in operational conditions: a contribution to an evidence-based approach to crime scene investigation and triage

DNA is nowadays swabbed routinely to investigate serious and volume crimes, but research remains scarce when it comes to determining the criteria that may impact the success rate of DNA swabs taken on different surfaces and situations. To investigate these criteria in fully operational conditions, DNA analysis results of 4772 swabs taken by the forensic unit of a police department in Western Switzerland over a 2.5-year period (2012-2014) in volume crime cases were considered. A representative and random sample of 1236 swab analyses was extensively examined and codified, describing several criteria such as whether the swabbing was performed at the scene or in the lab, the zone of the scene where it was performed, the kind of object or surface that was swabbed, whether the target specimen was a touch surface or a biological fluid, and whether the swab targeted a single surface or combined different surfaces. The impact of each criterion and of their combination was assessed in regard to the success rate of DNA analysis, measured through the quality of the resulting profile, and whether the profile resulted in a hit in the national database or not. Results show that some situations - such as swabs taken on door and window handles for instance - have a higher success rate than average swabs. Conversely, other situations lead to a marked decrease in the success rate, which should discourage further analyses of such swabs. Results also confirm that targeting a DNA swab on a single surface is preferable to swabbing different surfaces with the intent to aggregate cells deposited by the offender. Such results assist in predicting the chance that the analysis of a swab taken in a given situation will lead to a positive result. The study could therefore inform an evidence-based approach to decision-making at the crime scene (what to swab or not) and at the triage step (what to analyse or not), contributing thus to save resource and increase the efficiency of forensic science efforts.

Comparison of the biomechanical properties of a ventral cervical intervertebral anchored fusion device with locking plate fixation applied to cadaveric canine cervical spines

OBJECTIVE: To evaluate fixation properties of a new intervertebral anchored fusion device and compare these with ventral locking plate fixation. STUDY DESIGN: In vitro biomechanical evaluation. ANIMALS: Cadaveric canine C4-C7 cervical spines (n = 9). METHODS: Cervical spines were nondestructively loaded with pure moments in a nonconstraining testing apparatus to induce flexion/extension while angular motion was measured. Range of motion (ROM) and neutral zone (NZ) were calculated for (1) intact specimens, (2) specimens after discectomy and fixation with a purpose-built intervertebral fusion cage with integrated ventral fixation, and (3) after removal of the device and fixation with a ventral locking plate. RESULTS: Both fixation techniques resulted in a decrease in ROM and NZ (P < .001) compared with the intact segments. There were no significant differences between the anchored spacer and locking plate fixation. CONCLUSION: An anchored spacer appears to provide similar biomechanical stability to that of locking plate fixation.

Australia's National Mental Health Strategy and deinstitutionalization: some empirical results

Objective: To determine the role of the National Mental Health Strategy in the deinstitutionalization of patients in psychiatric hospitals in Queensland. Method: Regression analysis (using the maximum likelihood method) has been applied to relevant time-series datasets on public psychiatric institutions in Queensland. In particular, data on both patients and admissions per 10 000 population are analysed in detail from 1953-54 to the present, although data are presented from 1883-84. Results: These Queensland data indicate that deinstitutionalization was a continuing process from the 1950s to the present. However, it is clear that the experience varied from period to period. For example, the fastest change (in both patients and admissions) took place in the period 1953-54 to 1973-74, followed by the period 1974-75 to 1984-85. Conclusions: In large part, the two policies associated with deinstitutionalization, namely a discharge policy ('opening the back door') and an admission policy ('closing the front door') had been implemented before the advent of the National Mental Health Strategy in January 1993. Deinstitutionalization was most rapid in the 30-year period to the early 1980s: the process continued in the 1990s, but at a much slower rate. Deinstitutionalization was, in large part, over before the Strategy was developed and implemented.

Análisis de los residuos sólidos generados en áreas administrativas, académicas, bibliotecas y cómputos, de ciudad universitària en la UMSNH, Michoacán, México

El proyecto se enmarca dentro de Plan Ambiental Institucional (PAI) de la Universidad Michoacana de San Nicolás de Hidalgo (UMSNH), México, en lo referente a la gestión de residuos y tiene por finalidad analizar la tipología y composición de los residuos que se generan en algunas de las áreas de Ciudad Universitaria (CU). Para esto se realizó una metodología de recogida no selectiva de residuos puerta a puerta que se estructuró en dos fases, la primera, con el objetivo de obtener toda la información sobre el número y tipo de espacios de los edificios para luego elaborar y llevar a cabo el muestreo de los residuos, y la segunda, que se centró en la captura informática y gestión de los pesos de los mismos. De los datos obtenidos se concluyó que los residuos de mayor peso muestreado fueron el papel, la materia orgánica, el cartón y el vidrio transparente, los residuos de mayor generación per cápita fueron el papel, cartucho de impresora, CD y disquete. Finalmente, se concluye que la UMSNH no da tratamiento a los residuos que al ser depositados al aire libre contaminan su medio ambiente. Reciclándolos podrían obtenerse no sólo beneficios ambientales sino también económicos, que disminuirían el costo del reciclado devolviendo los residuos al ciclo productivo.

Salvia divinorum: an hallucinogenic mint which might become a new recreational drug in Switzerland.

Salvia divinorum Epling & Jativa is an hallucinogenic mint traditionally used for curing and divination by the Mazatec Indians of Oaxaca, Mexico. Young people from Mexican cities were reported to smoke dried leaves of S. divinorum as a marijuana substitute. Recently, two S. divinorum specimens were seized in a large-scale illicit in-door and out-door hemp plantation. Salvinorin A also called divinorin A, a trans-neoclerodane diterpene, was identified in several organic solvent extracts by gas chromatography-mass spectrometry. The botanical identity of the plant was confirmed by comparing it to an authentic herbarium specimen. More plants were then discovered in Swiss horticulturists greenhouses. All these data taken together suggest that many attempts exist in Switzerland to use S. divinorum as a recreational drug. This phenomenon may be enhanced because neither the magic mint, nor its active compound are banned substances listed in the Swiss narcotic law.

BPSK to ASK signal conversion using injection-locked oscillators-Part I: theory

This paper presents a new method and circuit for the conversion of binary phase-shift keying (BPSK) signals into amplitude shift keying signals. The basic principles of the conversion method are the superharmonic injection and locking of oscillator circuits, and interference phenomena. The first one is used to synchronize the oscillators, while the second is used to generate an amplitude interference pattern that reproduces the original phase modulation. When combined with an envelope detector, the proposed converter circuit allows the coherent demodulation of BPSK signals without need of any explicit carrier recovery system. The time response of the converter circuit to phase changes of the input signal, as well as the conversion limits, are discussed in detail.

Sähkölieden paistouunin energiatalouden analysointi ja parannusehdotusten kehittäminen

Diplomityön tavoitteena oli selvittää nykyisen sähkölieden paistouunin energiankulutuksen kriittisimmät kohteet sekä pohtia tulevaisuuden liesissä mahdollisesti käyttöön otettavia uusia, lieden energiatalouden kannalta edullisia ratkaisuja. Työn keskeisenä osana oli tutustua kotitalousliesien energiankulutuksen CENELEC:n EN 50304 standardiin, jonka perusteella uuneja tullaan tulevaisuudessa testaamaan energiamerkkiä varten. Standardin mukaisia kokeita tehtiin useilla nykytuotannossa olevilla sähköliesillä sekä lisäksi joillakin protomalleilla. Lisäksi diplomityössä määritettiin kokeellisesti uunin luukun osuus energiankulutuksesta, uunin lämpökapasiteetin pienentämisen vaikutus energiankulutukseen sekä vertailtiin eri eristemateriaaleja. Sähköliesien kilpailutilanne markkinoilla on kiristynyt vuosi vuodelta. Näin ollen pienet valmistuskustannukset ovat liesien kannattavan tuotannon edellytys. Onkin vaikea tehtävä määrittää uunin energiataloutta parantavia kehitysratkaisuja, jotka olisivat myös taloudellisesti kannattavia.

Edward W. Bowslaugh (1843-1923) was the son of Jacob and Anna (Beamer) Bowslaugh. Edward Bowslaugh married Mary Southward, and the couple had six children, Edgar Morley, Edward Freeman, twins Alfred Malcolm and Alice Mary, Annie Olivia, John Jacob and Mabel Florence. Edward W. Bowslaugh was a farmer, contractor and owner of the Grimsby Planing Mills in Grimsby, Ont. and Bowslaugh’s Planing Mill in Kingsville, Ont. The mills manufactured door and sash trim and other wood related products. Some customers contracted the firm to provide wood products for cottages being built at Grimsby Park, the Methodist camp ground. Some time before 1885 Edward Bowslaugh and his family moved to Kingsville, Ont. to open up a new planing mill and door and sash manufactory. He later sold the Grimsby Planing Mills to Daniel Marsh. The diaries and account books include many names of workers as well as friends and family members residing in the Grimsby and Kingsville areas. James M. Bowslaugh (1841-1882) was the son of Jacob and Anna (Beamer) Bowslaugh. James married first Anna Catharine Merritt and after her death in 1875 he married Mary Gee in 1877. James and Anna had three children, Eliza, James Herbert, George Hiram, all died very young. James and Mary Gee had one son, Charles Leopold Kenneth Frederich Bowslaugh, b. 1881. James Bowslaugh was a farmer and lumberman, much like his younger brother Edward. James’ early diaries often note the activities of himself and his brother Edward. Both Edward and James were heavily involved in the Methodist church, teaching or leading Sunday school and attending prayer meetings. Alfred M. Bowslaugh b. 1873 was the son of Edward W. Bowslaugh and his wife Mary Southward. The school notebook is from his days as a student in Kingsville, Ont.
