Objetivou-se com esse trabalho realizar a avaliação nutricional e a sugestão de um padrão alimentar para o gênero Chelonoidis sp., usando dados biométricos como o peso, o escore de condição corporal e o comprimento e a largura do casco e do plastrão. Foram utilizados 52 híbridos, de jabuti-piranga (Chelonoidis carbonaria) e jabuti-tinga (Chelnoidis denticulata), com 27 indivíduos do sexo masculino e os outros 25 do feminino. A dieta fornecida foi uma combinação de fontes de proteína, leguminosas, verduras e frutas disponíveis no local para observação do consumo e comportamento alimentar individual. Com base nisso, eles foram classificados de acordo com o aspecto casco, preferência alimentar e escore de condição corporal, o que refletiu no efeito de dominância e frequência alimentar por meio da observação dos jabutis em 12 momentos. Para a análise estatística dos dados foram utilizados os procedimentos de análise de variância (ANOVA) one way e posteriormente aplicado o teste de Tukey, sendo considerado o nível de significância quando P<0,05. A frequência de alimentação dos animais foi determinada como um padrão para distinguir animais obesos de desnutridos.

Authors: Freitas Gaby Soares de
Published: November 2018

O tamanduá-bandeira é um mamífero silvestre que pertence à família Myrmecophagidae. Devido à perda contínua de seu habitat natural a espécie foi considerada Vulnerável ao risco de extinção, por tal característica a conservação de tamanduás é um tema cada vez mais difundido. O objetivo do presente estudo é descrever o crescimento de um de tamanduá-bandeira (Myrmecophaga tridactyla) alimentado artificialmente em cativeiro através de curvas de crescimento geradas pelo Programa Prático de Modelagem (PPM) (GARCIA-NETO, 2018). Para realizar as curvas de crescimento foram utilizados dados não publicados do arquivo de fichas do Centro de Conservação da Fauna Silvestre (CCFS) do município de Ilha Solteira – SP, o período de coleta de dados foi de Jul-2015 à Jul-2017 e o animal foi submetido a dois tipos de dietas, uma dieta inicial e uma dieta para animais adultos. Os dados foram coletados das fichas, e tabelados no Excel 2010, a idade do animal foi de 30 dias no início e à partir desta idade inicial foram encontradas as demais idades. Os dados foram executados pelo modelo matemático de Richads: y = a [1+(b-1) e-c(x-d)]1/(1-b), sendo o input a idade do animal em dias e o output, o peso em kg. Foram encontrados os valores para a,b,c e d, sendo 38.6860, 1.56027, 0.00923, 291.7177, respectivamente. Conclui-se que o PPM foi eficiente para ajustar a curva de crescimento de um filhote de tamanduá-bandeira alimentado artificialmente.

Published: November 2018

Avaliou-se consumo voluntário e estimou-se ingestão de nutrientes por Psephotus haematonotus frente à oferta de diferentes alimentos. Foram distribuídas 21 aves em três tratamentos e sete repetições sendo T1: Ração extrusada (RE), girassol (G), alpiste (A) e painço (P); T2: RE+A+P; T3: RE. Foram determinados os teores de matéria seca (MS), proteína bruta (PB), extrato etéreo (EE), matéria mineral (MM), cálcio (Ca), fósforo (P) e energia bruta (EB) para cada alimento, bem como foi estimada a ingestão total (IT) de MS, nutrientes (g/dia) e EB (kcal/dia/kg) feita pelas aves.  Verificou-se diferença (p<0,0001) para ITMS entre os tratamentos sendo T3 e T2>T1 (6,10; 4,73; 2,74g MS/ave/dia, respectivamente). A ITEE diferiu entre os tratamentos (p<0,0001) onde T1 e T3 > T2 (0,467; 0,638; 0,155g EE/MS/dia). Houve diferença para ITEB (p=0,004), onde T3>T2>T1 (26,8; 19,99; 15,35g kcal/kg/dia), e ITPB (p<0,0001) onde T3>T2 e T1 (0,81; 0,58; 0,40g PB/MS/dia). Para ITCa (p=0,001) e ITP (p<0,0001) houve diferença entre os tratamentos sendo T3 (0,06g Ca/MS/dia e 0,025g P/MS/dia) > T1 e T2 (0,007; 0,021g Ca/MS/dia e 0,01; 0,013g P/MS/dia respectivamente). A oferta de diferentes alimentos resultou em maior consumo de MS proveniente de sementes em relação ao vindo de RE, demonstrando que, possivelmente, frente a livre oferta de sementes, as aves consomem alimentos mais palatáveis, sendo incapazes de balancear sua dieta pela ingestão de nutrientes.

Published: November 2018

Medidas de enriquecimento ambiental são necessárias para propiciar modificações no recinto que o deixem mais dinâmico e estimulante, visando comportamentos dos indivíduos mais semelhantes aos apresentados pela espécie em vida livre. O objetivo deste trabalho foi analisar o comportamento de bugios-ruivos, por meio da aplicação de enriquecimentos ambientais dos tipos alimentar, cognitivo e sensorial. Foram observados os comportamentos de um grupo de bugios subadultos e um de bugios adultos por dez minutos antes da instalação do enriquecimento (pré-enriquecimento) e dez minutos após sua instalação (pós-enriquecimento), totalizando 10 horas de registros comportamentais. Os resultados mostram que as reações dos animais à aplicação do enriquecimento do tipo alimentar foram mais efetivas pelos dois grupos, obtendo-se maior sucesso, porém é importante mencionar que estudos com diversos tipos de enriquecimento ambiental são fundamentais, visto que por meio destes, é possível avaliar o bem-estar de cada indivíduo e determinar quais devem ser mais utilizados em função das principais necessidades individuais.

Published: November 2018

Na natureza a calopsita possui uma alimentação composta por uma enorme variedade de alimentos, sendo que em cativeiro, sua alimentação geralmente é deficiente, pois a oferta de mistura de sementes como único alimento, pode acarretar falta de nutrientes e a longo prazo o desencadeamento de doenças. O objetivo desse estudo foi mensurar o consumo voluntário e estimar a ingestão de nutrientes em Nymphicus hollandicus. Para tanto, foram utilizadas 21 aves da espécie, distribuídas em delineamento inteiramente casualizado, em três tratamentos com sete repetições cada. Os tratamentos experimentais foram 1- Ração comercial extrusada para psitacídeos, semente de girassol, alpiste e painço;2- Ração comercial extrusada para psitacídeos, alpiste e painço e 3- Ração. O consumo de alimento, sobras e desperdício foram mensurados durante sete dias consecutivos. A ingestão de nutrientes foi estimada baseada na ingestão de matéria seca e na composição nutricional dos itens alimentares ofertados. As aves do T1 ingeriram 1,6 e 1,75x mais energia em relação às do T2 e T3 e ingeriram maior quantidade total de matéria seca e proteína bruta (g/ave/dia). Foi possível verificar que a relação Ca:P foi mantida somente no T3, estando T1 e T2 abaixo da relação recomendada.  Conclui-se que a disponibilidade de mais de um item alimentar resulta em aumento significativo na ingestão de MS, demonstrando a preferência dessa espécie por alimentos com maior palatabilidade.
Medial Unicompartmental Arthroplasty of the Knee
Authors: Jennings Jason M. , Kleeman-Forsthuber Lindsay T. , Bolognesi Michael P.
Published: November 2018

Indications for medial unicompartmental knee arthroplasty (UKA) have expanded over the past two decades. Proposed advantages include faster recovery, improved kinematics, and better functional outcomes compared with total knee arthroplasty (TKA) in age-matched control subjects. A focused preoperative examination and imaging is essential to identify appropriate surgical candidates. No difference has been demonstrated between fixed- and mobile-bearing implants for implant survivorship or patient-reported outcomes. The most common reasons for conversion to a TKA are aseptic loosening and progression of osteoarthritis. Ten-year survival for UKA in cohort studies has shown to be >90% with outcomes after conversion to TKA being similar to outcomes for revision TKA. Registries have consistently shown lower implant survival for UKA compared with that for TKA, which is likely secondary to use of several different implants by surgeons of varying levels of experience. UKA has the potential to be a cost-effective alternative to TKA in certain patient populations when performed at high-volume centers with advanced surgical techniques.
Course of the Femoral Artery in the Mid- and Distal Thigh and Implications for Medial Approaches to the Distal Femur: A CT Angiography Study
Authors: Maslow Jed I. , Collinge Cory A.
Published: November 2018

Introduction:

Unfamiliarity with the location of the femoral artery in the medial thigh has tempered surgeons' enthusiasm for medial approaches to the distal femur. The purpose of this study was to define the relationship of the femoral artery to the mid- and distal femur to assist in safely approaching the femur for fracture care.

Methods:

Fifteen patients undergoing CT with angiography (CTA) of the lower extremity (CTA) were evaluated. From three-dimensional CTA images, the distance of the artery at the anterior border, midsagittal line, and posterior border of the femur from the distal femur at both the adductor tubercle and medial femoral condyle was measured.

Results:

The average distances of the adductor tubercle to the femoral artery were 23.2 cm (±3.3), 18.8 cm (±3.4), and 14.3 cm (±4.1) at the level of the anterior border, midsagittal line, and posterior border of the femur, respectively. The descending genicular artery (DGA) originated 10.8 cm (±1.3) proximal to the adductor tubercle.

Discussion:

A wide safe zone exists in the medial distal femur. The artery crosses the midsagittal axis of the medial femur an average of 18.8 cm proximal to the adductor tubercle.
Scheuermann's Kyphosis: Diagnosis, Management, and Selecting Fusion Levels
Authors: Sardar Zeeshan M. , Ames Robert J. , Lenke Lawrence
Published: November 2018

Scheuermann's kyphosis (SK) is a rigid structural deformity of the thoracic spine defined radiographically as three or more contiguous vertebrae with at least 5° of wedging anteriorly. Prevalence of the disease is thought to be between 0.4% and 10%. The true cause of SK remains unclear; however, various theories include growth irregularities, mechanical factors, genetic factors, and/or poor bone quality as the causes. Patients with mild disease (less than 70°) generally have a favorable prognosis with good clinical outcomes. Most patients with SK are successfully treated nonsurgically with observation, anti-inflammatory medications, and physical therapy. Surgical intervention is indicated in patients with greater than 70° to 75° thoracic curves, greater than 25° to 30° thoracolumbar curves, intractable pain, neurologic deficit, cardiopulmonary compromise, or poor cosmesis. Because of advances in posterior spinal instrumentation, surgery can typically be performed through a posterior-only approach. When surgical treatment is planned, appropriate selection of the upper- and lower-instrumented vertebrae is important to achieve a well-balanced spine, preserve motion segments, and reduce the risk of junctional kyphosis.

Authors: Duda Anna , Stós Wojciech , Wiosna Magdalena
Published: November 2018

This study assesses the effects of the upper respiratory tract width at the level of the adenoid in patients with a normal and abnormal breathing route on basic parameters of the morphology of the facial skeleton. Aim. Comparison of skeletal parameters determining vertical (SNL/ML, NL/ML, NL/ML), sagittal (SNA, SNB) dimensions and type of facial rotation (the angle of the facial axis according to Ricketts) in the study and control groups and determination of the threshold value (a cut-off point) of width according to Holmberg, at which there is a deviation from the average values of basic parameters of morphology of the facial skeleton. Material and methods. The study included 221 patients treated at an orthodontic clinic in Kielce. Based on the medical history taken, clinical examination and subjective evaluation of the upper respiratory tract width according to Holmberg 112 patients were enrolled into the study group and 109 patients into the control group. The width of the upper respiratory tract was measured using the modified Holmberg method and parameters assessing the vertical (SNL/ML, NL/ML) and sagittal (SNA, SNB) dimensions, as well as the anterior angle of the Ricketts’ axis were measured using the analysis of lateral teleroentgenograms of the head. Results. All compared skeletal parameters indicated significant statistical differences between the study and control group. These differences were: Ricketts’ angle 6.5°, SNL/ML 8.5°, NL/ML 9.7°, SNA 2.4°, SNB 1.4°. Conclusions. The width of the upper respiratory tract at the level of the adenoid significantly affects values of skeletal parameters evaluating the vertical (SNL/ML, NL/ML) and sagittal (SNA, SNB) dimensions and the type of rotation of the facial axis. There is a correlation between a gradual decrease in the airway dimension according to Holmberg and an increase in the vertical dimension (SNL/ML, NL/ML) and anterior angle of the Ricketts’ facial axis (posterior rotation of the mandible) and a decrease in the sagittal dimension (SNA, SNB).
The use of 2D radiographs for the assessment of effectiveness of secondary alveolar bone grafting in patients with cleft lip and palate. A literature review
Authors: Stasiak Marcin , Wojtaszek-Słomińska Anna , Racka-Pilszak Bogna
Published: November 2018

Clefts of the lip and the palate (CLP) represent the most common craniofacial developmental defects. The CLP surgical treatment protocol involves an autogenous secondary alveolar bone grafting (SABG). Aim. The aim of the study was to review the methods for the SABG assessment in CLP patients based on 2D radiographs and the assessment of the effectiveness of the foregoing surgical procedure based on those methods. Material and methods. Papers, published in the years 1981-2018, regarding SABG assessment in CLP patients based on 2D radiographs were reviewed. Nineteen papers in which the material was closely associated with the study assumptions were qualified for the review. Results.major part of the papers under analysis use a single post-operative radiograph. The others are based on two or three radiographic projections. There are seven basic methods and three modified methods used for the assessment of SABG effectiveness. The SABG assessment methods based on 2D radiographs are similar to one another. The main criterion of surgery effectiveness is the position of the alveolar process edge within the cleft with relation to the tooth roots adjacent to the cleft. Said classification results differ in terms of the degree of complexity and the manner of presentation of the surgery outcomes. The Abyholm (Bergland) scale was the most commonly applied assessment method. As demonstrated in all the studies in which 2D radiographs were used, the SABG effectiveness varied from 71% to 95%. Conclusions.1. The SABG assessment methods based on 2D radiographs are a useful manner of surgical procedure assessment. 2. The studies in which the SABG assessment methods based on 2D radiographs are used demonstrate a high effectiveness of the SABG procedure. (Stasiak M, Wojtaszek-Słomińska A, Racka-Pilszak B.

Impacted canines – interceptive treatment
Authors: Abramczyk Joanna , Zadurska Małgorzata , Czochrowska Ewa
Published: November 2018

Canines, especially upper canines, are the second most frequently impacted permanent teeth, after third molars. Orthodontic extrusion of ectopic impacted canines is often complex, long-lasting and may lead to iatrogenic complications. In children, implementation of interceptive treatment helps to normalise the canine position in the alveolar process and its spontaneous eruption. Aim. The aim of the study was to review the literature regarding the methods of interceptive treatment for impacted maxillary and mandibular canines supported by relevant clinical examples. Material and methods. A review of literature on interceptive treatment of impacted canines has been performed for the period 1961–2018. The medical databases PubMed and Medline were used. Results. Extraction of deciduous maxillary canines and maxillary first deciduous molars, maxillary expansion with rapid maxillary expanders and transpalatal arches, also in combination with extraoral traction and space opening the dental arch with fixed appliances are effective methods of interceptive treatment in patients at the developmental age with impacted upper canines. There is no effective protocol for interceptive treatment for impacted mandibular canines described in the literature. Conclusions. The use of interceptive treatment in growing patients positively influences spontaneous eruption of ectopic impacted maxillary canines. Early clinical and radiological diagnosis of ectopic canine position is very important for success. (Abramczyk J, Zadurska M, Czochrowska E. Impacted canines – interceptive treatment.

Authors: Popławska Ewa , Tymczyna-Borowicz Barbara , Smyl-Golianek Monika , Wieczorek Katarzyna
Published: November 2018

Tooth eruption disorders are a significant problem in clinical practice of a dental surgeon. They are observed in three forms: retention/impaction, primary and secondary retention. A retained tooth is by definition fully formed and after its physiological eruption time it still remains in the bone. Primary retention is the result of a genetic defect in the eruption mechanism (a mutation in the PTHR1 gene) and it is diagnosed before tooth eruption, with characteristic retention of distal teeth in relation to the first tooth that is affected. Secondary retention of eruption is caused by ankylosis. Case report. The female patient, aged 15 years and 4 months, presented at the Outpatient Clinic of Maxillary Orthopaedics at the Dental Clinical Centre of the Medical University of Lublin. The radiological and intraoral examinations showed numerous tooth eruption disorders and hypodontia of the tooth 42. Treatment plan: A cone beam CT examination to determine the structure and location of retained teeth 13, 17 and the stage of reinclusion of the tooth 55. Scheduling a surgical procedure. Delaying orthodontic treatment – observation of eruption of teeth 13 and 17. Performing the radiological examination again, after 6 months, in order to assess the dimensions of the maxillary alveolar process near teeth 14 and 16. Discussion. Eruption disorders are often associated with other dental abnormalities, and therefore additional examinations are required. Due to its slow and asymptomatic course, reinclusion often remains unnoticed. Its recognition in the early stages of the patient's development allows to avoid the occurrence of dentoalveolar complications. Conclusions. CBCT in cases of eruption disorders of permanent teeth or reinclusion of deciduous teeth increases the likelihood of a correct diagnosis.

The purpose of this paper is to disclose youth assessment of Lithuanian housing policy. The paper discusses housing policy and the youth housing challenges. The empirical part of the paper is based on the Lithuanian youth original empirical research results “Housing Provision for the Youth in Lithuania: Opportunities and Problems” carried out in 2017–2018. This research was carried out in the framework of the project” Housing Provision for the Youth: Processes, Problems and Solutions in Lithuania (JABS)” (GER 007/17) funded by the Lithuanian Science Council National Research Program “Welfare Society”. The results of the survey research revealed that Lithuanian housing policy young people assess rather unfavourably. According to the respondents there is a lack of more active State role and regulation of housing policy, housing policy regulation, more effective action against “shadow” housing rental. Analysis of the research results according to the social demographics characteristics indicated that women are tend to stress more State support for the first housing provision, cash benefits and compensations for housing maintenance. Moreover, 30–35 years old persons indicated more State support for the first housing provision than representatives of the other youth age groups.DOI: http://dx.doi.org/10.5755/j01.ppaa.17.3.21959
Kikuchi-Fujimoto Disease: A Review
Authors: Perry Anamarija M. , Choi Sarah M.
Published: November 2018

Kikuchi-Fujimoto disease (KFD) is a rare entity characterized by subacute necrotizing lymphadenopathy and frequently associated with fever. Young adults of Asian ancestry are most commonly affected, but it has been reported worldwide. Despite many studies in the literature, the cause of KFD remains uncertain. Histologically, KFD is characterized by paracortical lymph node expansion with patchy, well-circumscribed areas of necrosis showing abundant karyorrhectic nuclear debris and absence of neutrophils and eosinophils. Three evolving histologic patterns—proliferative, necrotizing, and xanthomatous—have been recognized. By immunohistochemistry, histiocytes in KFD are positive for myeloperoxidase. There is a marked predominance of T cells in the lesions (with mostly CD8-positive cells) with very few B cells. The differential diagnosis of KFD includes infectious lymphadenitis, autoimmune lymphadenopathy (primarily systemic lupus erythematosus), and lymphoma. Clinicians and pathologists are poorly familiar with this entity, which frequently causes significant diagnostic challenges.
Melanotic Neuroectodermal Tumor of Infancy
Authors: Soles Brian S. , Wilson Allecia , Lucas David R. , Heider Amer
Published: November 2018

Context.—

Melanotic neuroectodermal tumor of infancy, albeit rare and generally regarded as benign, is an important tumor to recognize because of its rapid growth, potential for local recurrence, and small round blue cell morphology, which can lead to misdiagnosis of a malignant neoplasm.

Objective.—

To review its clinical presentation and immunomorphologic findings, and discuss common entities in the differential diagnosis.

Data Sources.—

The study involved PubMed searches, including multiple review articles, case studies, retrospective studies, selected book chapters, and University of Michigan cases.

Conclusions.—

Melanotic neuroectodermal tumor of infancy most commonly occurs in the bones of the head and neck region during the first year of life, but it can also present in other locations, including the central nervous system, testes, ovaries, and subcutaneous soft tissues. Histologically, it is composed of a biphasic population of cells, consisting of epithelioid melanin-producing cells and primitive neurogenic cells in a fibrocollagenous stroma. These microscopic findings, especially in small biopsies, can lead to a broad differential diagnosis that includes malignant small round blue cell tumors and malignant melanoma. Melanotic neuroectodermal tumor of infancy commonly has an infiltrative growth pattern, and anatomic constraints often lead to incomplete resection and local recurrence, requiring multiple surgical operations. Because melanotic neuroectodermal tumor of infancy can mimic a more aggressive and aggressively treated malignancy, recognition of this rare tumor is very crucial for pathologists.
Primary Cutaneous Composite Lymphomas
Authors: Chen Stephanie , Boyer Daniel , Hristov Alexandra C.
Published: November 2018

Composite lymphomas have been defined as 2 distinct subtypes of lymphoma occurring at a single anatomic site. Composite lymphomas limited to the skin are a rare occurrence and pose a unique challenge. Many reported cases within the skin are combined B-cell and T-cell lymphomas, typically mycosis fungoides and a low-grade B-cell lymphoma. These cases are challenging to recognize because lymphoid infiltrates within the skin often include a mixed population of B cells and T cells. In particular, reactive lymphoid proliferations (pseudolymphomas), primary cutaneous low-grade B-cell lymphomas, and primary cutaneous CD4+ T-cell lymphoproliferative disorder may show nearly equal numbers of B cells and T cells. In order to exclude these possibilities, overwhelming evidence in support of each lymphoma is helpful, including abnormal architecture, cytology, and immunophenotype, as well as molecular genetic evidence of clonality.
BIODEGRADATION OF SOLUTIONS FOR CHEMICAL NICKELATION
Authors: Mukhametova Gulnaz M. , Vinokurov Eugeny G. , Babusenko Elena S. , Skopintsev Vladimir D.
Published: November 2018

In this article, we examined the susceptibility of biodegradation of nickel-containing processing solutions and selected fungicidal products which meet the requirements. Technological solutions are characterized by such a priority parameter as the high deposition rate of the nickel coating were subject to biofouling by mycelial fungi, despite the presence of heavy metal ions in solutions. It is established that the development of mycelial fungi in solutions leads to their decomposition and deterioration of technological characteristics. The purpose of the study was to select the fungicide and its corresponding concentrations, which do not adversely affect the process rate and the quality of the coating. The following tasks were posed: investigation of the stability of various solutions for nickel plating to the action of microorganisms; identification of taxonomic affiliation of microorganisms that populate solutions; selection of fungicide, meeting the requirements for neutrality to the components of the solution, as there is no effect on the rate of the process. Based on the results of the experiment, the influence of microorganisms on the technological characteristics of solutions was determined. After the appearance and development of the colonies of mycelial fungi in time solutions, the pH changed to an alkaline region, the deposition rate of the Ni-P coating dropped. Copper sulfate, sodium tetraborate, lactic acid, chloroform was used as inhibitors. The use of copper sulfate fungicide in concentrations of 0.002-0.005 mol/l led to the inhibition of growth of the fungal colonies, but insignificant. Fungicide sodium tetraborate at a concentration of 0.03 mol/l had a noticeable inhibitory effect on the growth of fungi, and also had a positive effect on the rate of the process, which meets all the requirements for this compound.

In this work, we studied possibility to obtain bimetallic nanopowders by our modified solution combustion synthesis method using citric acid as a fuel. Stoichiometric amounts of metal nitrates with metal to metal ratios 1:1 and 1:2 and fuels with final oxidizer to fuel ratio of 1.75 were used as initial components to prepare aqueous solutions. The almost complete absence of metal oxide phases was confirmed by energy-dispersive X-ray spectroscopy. The X-ray diffraction analysis of obtained materials showed that all samples are pure bimetallic nanopowders with distorted cubic crystal structure of each metal. According to high resolution transmission electron microscopy the mean diameter of metallic particles are about 10 nm for all nanopowders. The calculated interplanar distances of crystals of metal particles as well as detailed scanning transmission electron microscopy studying showed uniform distribution of different metal spices into nanoparticles. Thus, we can conclude the nanopowders are bimetallic particles with co-integrated crystal structures of different metalic spices. We suppose, the possibility of solution combustion synthesis of bimetallic nanopowder in the air environment is due to a combination of type and amount of the fuels as well as technological conditions of the synthesis. These lead to rapid combustion process at low temperature. In addition, protective inert atmosphere appears above freshly synthesized metal nanopowders during thermal decompositions of the fuels that eventually prevent metal oxidation. Modified SCS method could be successfully used for one-step synthesis of complex oxide-oxide and metal-oxide core-shell nanostructures.

Published: November 2018

Methods for the formation of stable iron-containing suspensions that exhibit activity in the conversion of synthesis gas to C5+ hydrocarbons by the Fischer-Tropsch method are proposed. By XRD and DLS methods it was determined that the formation of the Fe2O3 phase with a bimodal particle size distribution of 50 and 295 nm results in the formation of a suspension by the drop thermolysis method − the gradual introduction of the active metal precursor solution into the dispersion medium (mixture of hydrocarbons C19H40-C32H66). Pulsed introduction of the active metal precursor solution (flash-pyrolysis) into the reactor zone leads to the formation of the Fe3O4 phase with a particle size of 91 and 460 nm. By TEM and AFM methods it was established that, regardless of the slurry forming method, large active phase particles are agglomerates of a finer fraction of particles with an average size of 42 nm. The obtained suspensions demonstrated high activity in the Fischer-Tropsch synthesis under the slurry-reactor conditions, however, the degree of CO conversion is slightly higher in the case of the catalytic suspension prepared by the drop thermolysis method. It is shown that the method of forming the suspension significantly affects the fractional composition of the resulting reaction products. In the presence of a suspension obtained by drop thermolysis, the yield of liquid hydrocarbons reaches 130 g/m3, while a high content of C19+ hydrocarbons is observed. The system formed by the method of flash-pyrolysis makes it possible to obtain mainly the gasoline (C5-C10) and diesel (C11-C18) hydrocarbon fractions. It should be noted that the products of the reaction have a high content of unsaturated hydrocarbons, which reaches 55%. Thus, the composition of the final products of FTS can be controlled by the choice of the catalytic suspension prepared method.

The compositions, methods of preparation and specific technological parameters of the production processes of cobalt catalysts for the synthesis of long chain hydrocarbons from synthesis gas were justified. To obtain C35+ selective catalysts by coprecipitation of active components, the carrier must provide a polydisperse distribution of the pore volume along the radii. This is achieved by hydrothermal treatment of the aluminosilicate carrier. To increase the strength of catalysts, it is possible to incorporate natural bentonites and diatomite of Roctov region deposits into the composition of coprecipitated catalysts. Effective catalytic systems are impregnated catalysts on Al2O3 and SiO2 supports with aluminum oxide promotion. The insertion of 5% - Al2O3 of cobalt metal mass allows to form crystallites of Co-CoO system with a size of 8 nm on the SiO2 surface, which provides high activity and selectivity for ceresin. Aluminum oxide is stabilized with Co3O4 in a structure with a high degree of ordering, without hindering its reduction, with the formation of cobalt predominantly with the crystalline structure of hexagonal close packing. Catalyst technologies are implemented in industry. The catalysts underwent continuous continuous testing (1000 h) in laboratory and industrial conditions, showed high stability of operation. During the entire operation, the yield of C5+ hydrocarbons was 159-171 g/Nm3 based on the processed synthesis gas. The long-chain hydrocarbons C35+ (ceresin) obtained are of high quality: the dropping point was 114-116 °C (37-40% ceresin content). Operation during the year of two industrial reactors at the Novocherkassk plant of synthetic products with a total volume of catalyst loading of 18 m3 confirmed the results of laboratory tests.

Emerging from the Shadows
Authors: Finlayson Alan James
Published: November 2018

John Norton (Teyoninhokaren) lived a multi-faceted life as diplomat, political leader, war chief, and author. Famous in his day and seen as “extraordinary” by contemporaries, he remained in the shadows of Tecumseh and Joseph Brant because of a lack of information and the negative portrayals of him by his adversaries. With the discovery of his personal correspondence and Journal, his character has been re-evaluated and his significance as a leader of the Six Nations, an important war chief in the War of 1812, and an author and historian, recognized. As well, his connections with Canada’s first internationally acclaimed author, Major John Richardson has been acknowledged and Norton recognized as a model for the character “Wacousta.” Little focus has been made of his “Wacousta” connection and an updated “overview” of his career has not appeared. Given his new status and what we now know of him, he is deserving of greater recognition and a fuller and up-to-date portrayal.
Crowdsourcing in medical research: theory and practice

Published: November 2018

The field of crowdsourcing for medicine has substantially expanded. We define crowdsourcing as an organization having a large group attempt to solve community problem, then share the solution with the broader public. Large groups of individuals can participate in medical research through open contests, hackathons, and related activities. The purpose of this literature review is to examine the definition, theory, and practice of crowdsourcing in medicine in order to facilitate crowdsourcing research. This multi-disciplinary review defines crowdsourcing for health, identifies theoretical antecedents (collective intelligence and open source models), and explores implications of the approach. Several critiques of crowdsourcing are also examined. Although several crowdsourcing definitions exist, there are two essential elements: (1) having a large group of individuals, including experts and non-experts, propose potential solutions; (2) sharing solutions with the public through implementation or open access materials. The public can be a central force in framing a common problem and developing feasible and compelling solutions. Crowdsourcing is related to, but distinct from other participatory research approaches. Crowdsourcing can be a useful for informing medical research, programs, and policy. A growing evidence base suggests that crowdsourcing in medicine can result in high-quality outcomes, broad community engagement, and more open science.
Comparison of genome sequences via projection extractor upon virtual mixer
Authors: Yu Hongjie , Zhang Yuan-Ting , Fang Wei
Published: November 2018

To compare multiple genome sequences, we transform each primary genome sequence into corresponding k-mer-based vectors. According to the principle of independent component analysis (ICA), the operation can be regarded as mixing multiple source genomic signals via several sensors, through which we can obtain the mixed vectors with equal-length from the corresponding genome sequences with different length. However, this mixing operation is performed by counting all the k-mer-based frequencies, instead of using real hardware of sensors. Thus, we name this preprocessing operation as virtual mixer (VM). Using ICA-based transformation, we projected all the vectors upon their independent components to capture the coefficients-based feature vector through the projection extractor (PE), which has been proved to have a property of distance preserving. Then, we used the proposed VMPE model upon three representative real datasets of genome sequence to test the efficiency for the model. The contrastive analysis results indicate that the proposed VMPE model performs well in similarity analysis.

Published: November 2018

Near Field Communication (NFC) is a very short-range type of radio communication that is compatible with other contactless communication technologies. It provides enormous possibilities, particularly given that it does not require any particular communication infrastructure. NFC technology has found possible application in contactless cards and mobile phone devices as a communication infrastructure which provides a platform for the development of NFC-based business services. This paper proposes a novel approach to forecasting the number of new users of NFC mobile phones based on fuzzy logic and the Norton-Bass diffusion model. The proposed approach is demonstrated through the case study.
Experimental Study for Optimizing Pedestrian Flows at Bottlenecks of Subway Stations
Authors: Luo Wei , Sun Lishan , Yao Liya , Gong Qingsheng , Rong Jian
Published: November 2018

In subway stations, bottlenecks are the narrowed areas that reduce pedestrian flows in channels. Because pedestrians at bottlenecks are forced to dense together, bottlenecks decrease flow efficiency and pedestrians’ transfer comfort and may trigger serious crowd disasters such as trampling. This study used pedestrian experiments to investigate the methods of optimizing pedestrian traffic at bottlenecks of subway stations. Three optimization measures were proposed and evaluated by analyzing the characteristics of pedestrian flows, including efficiency, smoothness, and security. In this paper, setting the rear sides of the bottleneck entrance as straight and surface funnel shapes is called straight funnel shape and surface funnel shape, respectively. Setting a column at a bottleneck is called the column obstacle. The results showed that when efficiency or security come first, a column on the left is recommended; when comfort comes first, a concave funnel is recommended; when comprehensiveness is prioritized, a column on the left is recommended. Moreover, the larger the volume, the optimization is more obvious. Although many  bottlenecks cannot be prevented when subway stations are constructed, the proposed optimization measures may help ease their adverse effects by improving facility efficiency, smoothness, and security, and by providing recommendations for designing and managing subway stations.
Wilayah rawan longsor di Kota Jayapura
Authors: Abrauw Rudolf D
Published: November 2018

Kota Jayapura merupakan salah satu wilayah yang berada di utara pulau Papua dan berhadapan langsung dengan Lempeng Pasifik, sehingga berpotensi terhadap bencana geologi, salah satunya adalah longsor. Walaupun demikian, longsor yang terjadi tidak hanya dipengaruhi oleh pergerakan Lempeng Pasifik (karena keterdapatan sesar/faults), tetapi juga kemiringan lereng yang bervariasi dari dataran rendah (0-8%) sampai perbukitan (>45%), kondisi litologi dan iklim. Penelitian ini bertujuan untuk memetakan wilayah rawan longsor berbasis Sistem Informasi Geografis (SIG) dengan menggunakan dua model yaitu, [1] model pendugaan longsor Direktorat Vulkanologi dan Mitigasi Bencana Geologi (DVMBG) tahun 2005 dengan paramater curah hujan, geologi, jenis tanah, lereng dan penggunaan lahan; dan [2] model pendugaan longsor kombinasi dari Pusat Penelitian Tanah dengan parameter kemiringan lereng, curah hujan, geologi, jenis tanah, jarak sesar/faults dan kerapatan vegetasi. Hasil kedua model diverifikasi dengan data kejadian longsor selama periode tahun 2002-2014. Hasil penelitian menunjukkan bahwa aplikasi kedua model memperlihatkan perbedaan sebaran wilayah rawan longsor. Model pertama menghasilkan luas wilayah rawan longsor dengan klasifikasi tinggi sebesar 16780 Ha, sementara model kedua tercatat hanya 2184 Ha. Hasil verifikasi dengan data lapangan menunjukkan bahwa model kedua lebih representatif dan dapat digunakan untuk mengindentifikasi wilayah rawan longsor di Kota Jayapura

Letak geografis Indonesia mengakibatkan perikanan di Selat Sunda turut terkena dampak dari dinamika iklim global. Salah satunya yaitu fenomena ENSO (El Nino-Southern Oscillation) di Samudera Pasifik yang mempengaruhi musim dan perairan laut di Indonesia. Perikanan di Selat Sunda memiliki komoditi berupa ikan pelagis yang wilayah potensialnya dapat diperkirakan dari parameter-parameter oseanografi berupa suhu permukaan laut (SPL) dan konsentrasi klorofil-a di perairan laut. Dinamika parameter oseanografi secara spasial dan temporal akibat variasi fenomena ENSO dapat diidentifikasi dari citra satelit Aqua yang membawa sensor MODIS. Informasi wilayah potensi ikan pelagis dibutuhkan untuk membantu efektifitas kegiatan perikanan dan menambah produksi perikanan tangkap. Parameter-parameter oseanografi bulanan di Selat Sunda ditampal berdasarkan 4 variasi musim dalam setahun pada setiap variasi fenomena ENSO dan diklasifikasikan berdasarkan kelas potensial sedang, potensial, dan sangat potensial. Hasilnya, wilayah potensi ikan pelagis yang sangat potensial di Selat Sunda pada fenomena La Nina dan El Nino lebih besar dibanding pada kondisi normal dan terjadi pada musim timur hingga peralihan II. Sebarannya berada di Samudera Hindia di sebelah barat Selat Sunda.

Histological analysis of post-eruption tooth wear adaptations, and ontogenetic changes in tooth implantation in the acrodontan squamate Pogona vitticeps
Authors: Haridy Yara
Published: November 2018

Teeth have been a focus of research in both extinct and extant taxa alike; a significant portion of dental literature is concerned with dental patterning and replacement. Most non-mammalian vertebrates continuously replace their dentition but an anomalous group of squamates has forgone this process in only having one tooth generation; these squamates all have apically implanted teeth, a condition known as acrodonty. Acrodont dentition and various characteristics attributed to it, including a lack of replacement, have often been defined ambiguously. This study explores this type of implantation through histology in the ontogeny of the acrodont agamid Pogona vitticeps. The non-replacing teeth of this squamate provides an opportunity to study wear adaptations, maintenance of occlusion in a non-mammalian system, and most importantly post-eruption changes in the tooth bone interface. In this study the post-eruption changes combined with dental wear likely gives the appearance of acrodont implantation.
