Die Mumienbinde des Monthemhat (Turin Cat. 1873.2) – Ein weiterer Beleg für die Zusatzkapitel 173 und 174
Authors: Töpfer Susanne
Published: January 2018

The mummy bandage of Monthemhat, son of Nestanetjeretten, carries Book of the Dead Spell 133 and parts of two funerary spells which were added to the corpus of Book of the Dead spells after the Third Intermediate Period. Since Supplementary Chapters 174 and 173 – according to Pleyte's numbering – are (so far) attested only on papyrus Leiden T 31, this mummy bandage must be regarded as a unique example of those compositions. The aim of the article is to make the texts on the bandage available in transliteration, translation and commentary in order to provide a basis for future Egyptological discussion about the contextualization of these supplementary chapters. It is most likely that the Pleyte spells 173 and 174 were not originally intended to be part of the Book of the Dead; rather, they must have originated as Osirian liturgies and were added into the corpus of funerary texts at a later date. The owner of the mummy bandage, named Monthemhat, seems to be identical with a member of a family of Theban priests attested from the Ptolemaic till the early Roman Period on the evidence of numerous funerary papyri and temple graffiti. According to the known genealogy of that family, Monthemhat lived in the 2nd half of the 1st cent. BC and/or the early 1st cent. AD. The Turin mummy bandage Cat. 1873.2 may thus well be the latest known attestation of Book of the Dead spells on textiles.

ملخص البحث:

لفائف مومياء منتو-م-حات، ابن نس-تا-نتشرت-تن، تحمل التعويذة (133) وأجزاء من إثنين من التعاويذ الجنائزية التى أضيفت كمدونة (كمجموعة) لتعاويذ كتاب الموتى بعد عصر الإنتقال الثالث. بما أن الفصول التكميلية أرقام (173 ، 174 ) تم توثيقها فقط وفقاً لترقيم بلينى على بردية ليدن ( T 31 )، يجب إعتبار لفائف هذة المومياء كمثال فريد لهذة التكوينات. فالهدف من هذا المقال هو جعل النصوص الموجودة على اللفافة متاحة كتابةً وترجمةً وتعليقاً وذلك من أجل توفير أساس لمناقشات علم المصريات فى المستقبل فى سياق هذة الفصول التكميلية.

كما أنه من الواضح أن تعاويذ بلينى أرقام (173 ، 174 ) لم يكن القصد منها فى الأساس أن تكون جزءاً من كتاب الموتى بل بدلاً من ذلك نشأت كطقوس دينية أوزورية وأضيفت لأصول هذه النصوص الجنائزية فى وقت لاحق. ويبدو أن صاحب لفائف المومياء متشابه لعضو من أعضاء عائلة كهنة طيبة والتى أستمرت من العصر البطلمى وحتى الفترة المبكرة من العصر الرومانى كدليل على العديد من البرديات الجنائزية ونقوش المعابد. وطبقاً لعلم الإنساب المعروف لهذه العائلة فإن منتو-م-حات قد عاش فى النصف الثانى من القرن الأول قبل الميلاد أو فى أوائل القرن الأول الميلادى. لفائف مومياء تورين والتى تحمل رقم كتالوج Cat. 1873.2 ربما أنها أحدث إثبات معروف لنصوص كتاب الموتى مكتوبة على النسيج.
Investigación Acción Participativa (IAP) como Elemento de Fortalecimiento Educativo en la Escuela Bolivariana “El Paramito”, Estado Mérida
Authors: Pérez Paredes María del Carmen
Published: January 2018

La investigación acción participativa es una metodología que en los procesos de participación local ha logrado éxitos en su aplicación. En este artículo se revisa su aplicación en la Escuela Bolivariana “El Paramito” del Municipio Miranda Estado Mérida, tratando de incentivar la toma de decisiones democráticas mediante procesos participativos donde la influencia del ambiente sobre el saber mismo juega un papel transcendental. En el inicio de esta investigación la problemática encontrada fue la débil formación en los procesos de participación de la comunidad escolar. Por lo tanto, luego de varias jornadas de interacción con los actores educativos se propuso formar a la comunidad escolar en la U.E.B. “El Paramito” mediante de la investigación acción participativa como estrategia de acción socio-cultural aplicando el proyecto educativo comunitario. El paradigma que se utiliza en la investigación es el crítico – reflexivo entre la teoría y la práctica. La metodología utilizada es la Investigación Acción Participativa, Kemmis y sus colaboradores (1988) con el modelo comunitario a seguir. Según Fals Borda (1981) la IAP se relaciona más con una actividad de investigación propia de base popular sobre su realidad que con una acción receptiva de investigación realizada por élites ajenas a ellas. La validación de la información se ha obtenido mediante la aplicación de herramientas de calidad tales como participación comunitaria, reuniones formales e informales, informes, fotografías, diagrama causa-efecto utilizando el método de triangulación que supone el empleo de distintas estrategias que permiten validar las proposiciones teóricas-prácticas en los diferentes niveles de análisis.

Cuando planteamos crear la Revista Scientific
Authors: Martínez Molina Oscar Antonio
Published: January 2018

Cuando planteamos crear la Revista Scientific, nos surgieron numerosas dudas sobre ¿Cuál iba a ser el tratamiento a seguir para el desarrollo de la misma?. Por un lado, necesitábamos crear unas bases comunes en cuanto a sus aspectos más éticos y morales para que los autores aplicasen siempre los mismos criterios. Con esto no se pretende tan sólo conseguir una unidad editorial, sino establecer unas pautas a seguir a lo largo de la publicación, de modo que se facilite la lectura y comprensión de los contenidos desde el respeto a la información, a las fuentes, pero sobre todo a los/as lectores/as. Las normas creadas, son por lo tanto, las pautas a seguir por los autores/as que aparecen en nuestra publicación, los cuales deben tener en cuenta estas normas básicas. Otro punto a abordar fue la selección de un equipo disciplinario y multidisciplinario a nivel internacional que se encarga de la valoración de las producciones científicas, equipo de alta factura de diferentes Universidades y Organizaciones reconocidas a Nivel Mundial.

Sobre la base de las consideraciones anteriores, se plantea la cuestión de decidir, qué se puede o se debe, y qué no se puede o no se debe contar, sino más bien en el modo de exponer y explicar las informaciones del modo más éticamente correcto desde la perspectiva deontológica del articulista.

Hay que destacar que Scientific trata de servir de complemento y herramienta informativa tanto a docentes, como al público en general.

Tenemos como objetivo, difundir el conocimiento científico y tecnológico, a través de los resultados originales, producto de investigaciones científicas, que representen una contribución para el desarrollo de la ciencia y la tecnología. Incluye trabajos, productos de investigaciones científicas y reflexiones teóricas que, por su relevancia, ameriten publicarse, y de esta forma contribuyan a visibilizar la producción intelectual en las áreas de la educación y ciencias sociales.

La Revista Scientific, está dirigida a la audiencia académica en sus diferentes niveles (Inicial, Básica, Universitaria) así como también a la comunidad científica en general.

Cabe agregar que las aportaciones no materiales tienen que ver con el contenido de la publicación en forma de artículos realizados por colaboradores más o menos regulares. En ocasiones la publicación llega a acuerdos de colaboración para poder difundir la labor que se realiza desde la misma, por ejemplo, cubrir un evento de una Sociedad Científica a cambio de que nos cedan un espacio de autopromoción en el que podamos seguir buscando socios.
Expectativas y Percepciones del Servicio Educativo en la Universidad Nacional Abierta (Centro Local Mérida, Venezuela)
Authors: Molina Gutiérrez Teresa de Jesús , Molina de Sánchez Belkis , González Zuñiga Luis Enrique
Published: January 2018

El objetivo de este estudio fue interpretar la relación existente entre las expectativas y las percepciones que posee el personal acerca de la calidad del servicio educativo que se ofrece en el Centro Local Mérida (Universidad Nacional Abierta), entonces, se empleó el modelo conceptual de calidad de servicio SERVQUAL, complementado con el enfoque cualitativo. Los informantes fueron 15 asesores, 20 estudiantes y 5 miembros del personal administrativo, los datos se recolectaron mediante la entrevista semiestructurada y se interpretaron con el análisis de contenido. Los resultados indican que no hay satisfacción con el servicio educativo o esa satisfacción es muy baja, porque las expectativas que se generan antes de recibirlo no son superadas por el valor que se percibe, lo cual es un indicador de ausencia de calidad de servicio. Por otra parte, lograr la calidad en el servicio prestado es responsabilidad de todos los involucrados ya que la complejidad de los roles cumplidos en la dialéctica educativa conlleva a que el personal actúe, simultáneamente, como clientes y como prestadores del servicio.

Planeación de la Educación Ambiental en el Ámbito Universitario: Una Mirada Transdisciplinaria
Authors: Montesinos de Rodríguez Emilia
Published: January 2018

La investigación se dirige a producir una reflexión ontoepistémica sobre la planeación de la Educación Ambiental en el ámbito universitario con enfoque transdisciplinar. Se abordó con el paradigma interpretativo, métodos hermenéuticos y dialectico e investigación documental. La información recopilada da cuenta de una fiabilidad hermenéutica, recurriendo a la categorización, estructuración, contrastación y teorización. Los resultados reflejan que en la educación universitaria han predominado los postulados centrados en la enseñanza unidireccional, fragmentada, disciplinar, con parcelamiento de los saberes. Desde el diseño de los programas hasta la praxis académica, la construcción del conocimiento se hace de forma aislada con tendencia a formar estudiantes poco motivados a interactuar en el escenario donde se desenvuelven e indiferentes ante los problemas socio ambientales. No se asume la planeación de la Educación Ambiental como forma activa de articular la praxis educativa con la situación problemática del medio ambiente que hoy enfrenta la humanidad. En conclusión, la planeación de la Educación Ambiental en el ámbito universitario debe girar en torno a la complementariedad entre las diversas áreas del conocimiento, donde se logre una actitud reflexiva y trascendente para la enseñanza de orden superior, en la cual la realidad ambiental y social se conciba como fenómenos cambiantes y complejos.

Authors: Gupta Urvashi , Shrestha Ruchi , Samdurkar Ashok P , Shahi Anita
Published: January 2018

BACKGROUND: Ocular malignant tumors are relatively rare compared to other eye lesions, require immediate diagnosis and management. But ignorant care due to unawareness of persons can result into debility, loss of vision, and occasionally life is jeopardized.1 The aim of the study is to determine the frequency of most common neoplastc lesions of conjunctiva with histopathologically confirmed diagnosis. MATERIAL AND METHODS: It was a retrospective cross-sectional study done in a period of two years (January 2011  December 2012) that included120 patients who presented  with conjunctival lesions to the pathology department of  Universal College of Medical Science, Bhairahawa, Nepal.  RESULTS: In this study out of 120 biopsies which were histopathologically diagnosed as conjunctival neoplasms were categorized into benign, dysplastic and malignant lesion and was common after second decade of life. Majority of cases (75 cases, 62.5%) were categorized as benign lesion with predominance of squamous papilloma (n=25) and nevus (n=21), followed by malignant lesion (27 cases, 22.5%) and dysplastic lesions (18 cases, 15%). Amongst malignancies, squamous cell carcinoma (SCC) was the most prevalent and a case of malignant melanoma was studied. Dysplastic lesion included conjunctival intraepithelial neoplasia (CIN) with and without squamous papilloma. CONCLUSION: Histopathology plays an important role in diagnosis of conjunctival lesions and rules out different categories of neoplastic lesions on routine basis. In this study Squamous cell carcinoma (SCC) 20.01% is the most common malignant tumor of conjunctiva. The next majority of cases diagnosed as the verrucuous carcinoma 1.66% and malignant melanoma 0.83% maximum case of malignant cases diagnosed in the age group of more than 50 years.  Journal of Universal College of Medical Sciences (2016) Vol.04 No.01 Issue 13, Page: 32-35

Comparison of Box-Behnken, Face Central Composite and Full Factorial Designs in Optimization of Hempseed Oil Extraction by n-Hexane: a Case Study
Authors: Stamenković Olivera S. , Kostić Milan D. , Radosavljević Dragana B. , Veljković Vlada B.
Published: January 2018

Statistical multivariate methods like Box-Behnken, face central composite and full factorial designs (BBD, FCCD and FFD, respectively) in combination with the response surface methodology (RSM) were compared when applied in modeling and optimization of the hempseed oil (HSO) extraction by n-hexane. The effects of solvent-to-seed ratio, operation temperature and extraction time on HSO yield were investigated at the solvent-to-seed ratio of 3:1, 6.5:1 or 10:1 mL/g, the extraction temperature of 20, 45 or 70 °C and the extraction time of 5, 10 or 15 min. All three methods were efficient in the statistical modeling and optimization of the influential process variables and led to almost the same optimal process conditions and predicted HSO yield. Having better statistical performances and being economically advantageous over the FFD with repetition, the BBD or FCCD combined with the RSM is recommended for the optimization of liquid-solid extraction processes.
Introduction of a Cost Effective Method for Analysing Engine Intake Ice Removal Device for Small Aircraft
Authors: Bicsák György , Veress Áprád , Erdősi Máté , Hanzal Vítězslav
Published: January 2018

As the need for personal air transport increases significantly, new aircraft and/or its components are required to be designed and developed together with expectations for guarantying the high level flight safety. Since smaller aircraft manufacturers don’t have the infrastructural and experimental resources for complex investigations, analysis of engine components with especial care for the behaviour of particle separation components in the inlet air duct for example, smarter, more efficient solutions have to be developed. CFD software gives an opportunity to simulate the trajectories of different type of particles, such as hailstones, dust, or even liquid water droplets. Hence, in this study an upper-wing type, two engines thrusted, small turboprop aircraft’s integrated engine air intake device has been analysed, to prove the effectivity of the aircraft performance in the considered raining and icing conditions. The flow field has been discretized with a detailed, hybrid mesh using hexa elements at the simpler parts, and tetra elements, where the geometry is more complex. Inflation layers have been inserted on the wall-type surfaces, with especial care to the problematic parts, where the y+ number is predictably higher. The inlet boundary conditions of the model have been extracted from a larger, complex pre-simulation, performed in a previous study. Standard Reynolds Averaged Navier-Stokes equations have been considered with Shear Stress Transport turbulence model. Solid (ice) and liquid particles have been defined, and their trajectories are investigated by using fully coupled model. The interaction of the wall-fluid particle has been taken into consideration.
Innovation Potentials and Pathways Merging AI, CPS, and IoT
Authors: Klumpp Matthias
Published: January 2018

Recent advances in the areas of Artificial Intelligence (AI) in the informatics field, Cyber-Physical Systems (CPS) in the production field, and Internet of Things (IoT) in the logistics and transportation field have induced a tremendous growth and innovation potential for global value chain setups. The question is not if further innovation and automation will happen but when—sooner than later—and how. Independent of physical production innovations (additive manufacturing) the information integration and decision autonomy tendencies themselves will drive new supply chain and customer interaction designs and business models. This article presents a technology forecast model based on extensive descriptions of developments by field as well as interaction traits. Results suggest that the crucial element in AI and technology application in logistics will be the human factor and human-artificial cooperation capacities and attitudes.

Entropy of Entanglement between Quantum Phases of a Three-Level Matter-Radiation Interaction Model
Authors: Quezada Luis , Nahmad-Achar Eduardo
Published: January 2018

We show that the entropy of entanglement is sensitive to the coherent quantum phase transition between normal and super-radiant regions of a system of a finite number of three-level atoms interacting in a dipolar approximation with a one-mode electromagnetic field. The atoms are treated as semi-distinguishable using different cooperation numbers and representations of SU(3), variables which are relevant to the sensitivity of the entropy with the transition. The results are computed for all three possible configurations ( Ξ , Λ and V) of the three-level atoms.
Economic, Energetic, and Environmental Performance of a Solar Powered Organic Rankine Cycle with Electric Energy Storage in Different Commercial Buildings
Authors: Spayde Emily , Mago Pedro , Luck Rogelio
Published: January 2018

This paper presents an analysis to determine the economic, energetic, and environmental benefits that could be obtained from the implementation of a combined solar-power organic Rankine cycle (ORC) with electric energy storage (EES) to supply electricity to several commercial buildings including a large office, a small office, and a full service restaurant. The operational strategy for the ORC-EES system consists in the ORC charging the EES when the irradiation level is sufficient to generate power, and the EES providing electricity to the building when there is not irradiation (i.e., during night time). Electricity is purchased from the utility grid unless it is provided by the EES. The potential of the proposed system to reduce primary energy consumption (PEC), carbon dioxide emission (CDE), and cost was evaluated. Furthermore, the available capital cost for a variable payback period for the ORC-EES system was determined for each of the evaluated buildings. The effect of the number of solar collectors on the performance of the ORC-EES is also studied. Results indicate that the proposed ORC-EES system is able to satisfy 11%, 13%, and 18% of the electrical demand for the large office, the small office and the restaurant, respectively.
Lithium-Ion Battery Online Rapid State-of-Power Estimation under Multiple Constraints
Authors: Xiang Shun , Hu Guangdi , Huang Ruisen , Guo Feng , Zhou Pengkai
Published: January 2018

The paper aims to realize a rapid online estimation of the state-of-power (SOP) with multiple constraints of a lithium-ion battery. Firstly, based on the improved first-order resistance-capacitance (RC) model with one-state hysteresis, a linear state-space battery model is built; then, using the dual extended Kalman filtering (DEKF) method, the battery parameters and states, including open-circuit voltage (OCV), are estimated. Secondly, by employing the estimated OCV as the observed value to build the second dual Kalman filters, the battery SOC is estimated. Thirdly, a novel rapid-calculating peak power/SOP method with multiple constraints is proposed in which, according to the bisection judgment method, the battery’s peak state is determined; then, one or two instantaneous peak powers are used to determine the peak power during T seconds. In addition, in the battery operating process, the actual constraint that the battery is under is analyzed specifically. Finally, three simplified versions of the Federal Urban Driving Schedule (SFUDS) with inserted pulse experiments are conducted to verify the effectiveness and accuracy of the proposed online SOP estimation method.

Authors: Perea-Moreno Alberto-Jesus , Hernandez-Escobedo Quetzalcoatl , Garrido Javier , Verdugo-Diaz Joel
Published: January 2018

The aim of this study is to examine the possibility of using a stand-alone photovoltaic system (SAPVS) for electricity generation in urban areas in Southern Mexico. In Mexico, an urban area is defined as an area where more than 2500 inhabitants live. Due to constant migration from the countryside to the cities, the number of inhabitants of urban localities has been increasing. Global horizontal irradiation (GHI) data were recorded every 10 min during 2014–2016 in Coatzacoalcos in the state of Veracruz located on 18°08′09″ N and 94°27′48″ W. In this study, batteries represented 77% of the total cost, 12 PV panels of 310 W could export 5.41 MWh to the grid, and an inverter with an integrated controller and charger was selected, which decreased the initial cost. The city of Coatzacoalcos was chosen because the average annual temperature is 28°, with an average relative humidity of 75% and an average irradiance of 5.3 kWh/m2/day. An emission factor 0.505 tCO2/MWh of greenhouse gases (GHG) were obtained, based on the power system, the reduction of net annual GHG would be 11 tCO2 and a financial revenue of 36.951 × 103 $/tCO2 would be obtained. Financial parameters such as a 36.3% Internal Rate Return (IRR) and 3.4 years payback show the financial viability of this investment. SAPVSs in urban areas in Mexico could be a benefit as long as housing has a high consumption of electricity.
Mechanism and Prevention of a Chock Support Failure in the Longwall Top-Coal Caving Faces: A Case Study in Datong Coalfield, China
Authors: Li Zhu , Xu Jialin , Yu Shengchao , Ju Jinfeng , Xu Jingmin
Published: January 2018

Longwall chock support failures seriously restrain the safety and high-efficiency of mining of extra thick coal seams, as well as causing a great waste of coal resources. During longwall top-coal caving (LTCC), the influential effect of the properties and the movement regulation of top-coal on strata behavior cannot be ignored, since the top-coal is the medium through which the load of the overlying strata is transferred to the chock supports. Taking Datong coalfield as an example, the mechanism of a chock support failure in the LTCC face was investigated. Research findings indicated that the hard top-coal and insufficient chock support capacity were primary reasons for chock support failure accidents. On account of the field-measured results, a new method to determine support capacity was proposed, which fully took the impact of the top-coal strength into consideration. The calculation revealed that the required support capacity had exceeded the existing production maximum, at about 22,000 KN. Since it was unrealistic to simply increase chock support capacity, other approaches, according to the theoretical analysis, were proposed, such as lowering the integrity and strength of the top-coal, and upgrading its crushing effect to weaken the support load effectively during the weighting period, which reduces the likelihood of chock support accidents occurring. Based on this, hydraulic fracturing for hard top-coal and optimization of the caving process (chock supports raised up and down repeatedly by manual operation before moving forward) were presented. The proposed solutions were successfully applied in LTCC-west8101 for subsequent mining and achieved substantial benefits. The above research provides valuable references and ideas for the control of strata behavior to ensure safe and highly efficient mining in extremely thick and hard coal seams with the LTCC method.

The AMP-Activated Protein Kinase Homolog Snf1 Concerts Carbon Utilization, Conidia Production and the Biosynthesis of Secondary Metabolites in the Taxol-Producer Pestalotiopsis microspora
Authors: Wang Dan , Li Yingying , Wang Haichuan , Wei Dongsheng , Akhberdi Oren , Liu Yanjie , Xiang Biyun , Hao Xiaoran , Zhu Xudong
Published: January 2018

Highly conserved, the Snf1/AMPK is a central regulator of carbon metabolism and energy production in the eukaryotes. However, its function in filamentous fungi has not been well established. In this study, we reported functional characterization of Snf1/AMPK in the growth, development and secondary metabolism in the filamentous fungus Pestalotiopsis microspora. By deletion of the yeast SNF1 homolog, we found that it regulated the utilization of carbon sources, e.g., sucrose, demonstrating a conserved function of this kinase in filamentous fungus. Importantly, several novel functions of SNF1 were unraveled. For instance, the deletion strain displayed remarkable retardation in vegetative growth and pigmentation and produced a diminished number of conidia, even in the presence of the primary carbon source glucose. Deletion of the gene caused damages in the cell wall as shown by its hypersensitivities to Calcofluor white and Congo red, suggesting a critical role of Snf1 in maintaining cell wall integrity. Furthermore, the mutant strain Δsnf1 was hypersensitive to stress, e.g., osmotic pressure (1 M sorbitol), drug G418 and heat shock, though the mechanism remains to be illustrated. Significantly, disruption of the gene altered the production of secondary metabolites. By high-performance liquid chromatography (HPLC) profiling, we found that Δsnf1 barely produced secondary metabolites, e.g., the known product pestalotiollide B. This study suggests that Snf1 is a key regulator in filamentous fungus Pestalotiopsis microspora concerting carbon metabolism and the filamentous growth, conidiation, cell wall integrity, stress tolerance and the biosynthesis of secondary metabolites.

Few data are available regarding viral hepatitis perception among the general global population. The present study aims to estimate the perception of viral hepatitis in a cohort of individuals living in two geographical regions of Brazil: North (Manaus city (MA)) and Southeast (Rio de Janeiro city (RJ)). A cross-sectional, descriptive study was carried out among 287 subjects recruited in MA (134) and RJ (153). All individuals answered a questionnaire assessing socio-demographic characteristics and viral hepatitis awareness. Participants’ responses were scored and divided using interquartile values. Associations between socio-demographic characteristics and knowledge were also evaluated. Interquartile analysis scored 0–21 correct answers as “Very Weak”; 22–27 as “Weak”; 28–31 as “Intermediate”; and 32–47 as “Desirable”. Mean ± standard deviations (SD) of correct responses were weak in both MA (24.1 ± 7.0) and RJ (26.3 ± 7.3). Bivariate analysis showed an association between viral hepatitis awareness and both education level (p < 0.001) and family income (p < 0.01). Desirable scores were more common in female participants (61%), those aged between 21–30 years (40%), those with a secondary education (51.7%), those who received high income (31.6%), and those from RJ (70.0%). Health education campaigns in these cities are recommended to increase knowledge and reduce the transmission of these viruses.

Childhood diarrhea is one of the leading causes of morbidity and mortality in children under five in low and middle-income countries, second only to respiratory illness. The mouthing behavior that is common in children exposes them to fecal-orally transmitted pathogens that can result in diarrhea; however, there is a need for further evidence on specific exposure routes. This study describes the frequency and diversity of two important routes of enteric pathogen exposure among infants 3–9 months of age: infant oral contact behavior and caregiver handwashing behavior. Data were collected through structured observations of 25 index infants for the oral contact data and 25 households for the caregiver handwashing data in a peri-urban setting in Kisumu (Obunga), Kenya. Breast was the most common type of oral contact event with an average of 3.00 per observation period and 0.5 events per hour. This was followed by a range of physical objects with an average of 2.49 per observation and 0.4 events per hour. The “infant’s own hands” was the third most common oral contact, with an average of 2.16 events per hour, and 0.4 oral contact events per hour. Food and liquids were the 4th and 5th most common oral contact events with an average of 1.64 food contacts and 0.52 liquid oral contact events per observation period. Feeding events, including breastfeeding, were the most commonly observed key juncture—71% of total junctures observed were caregivers feeding children. This was followed by child cleaning (23%), caregiver toilet uses at (4%), and lastly food preparation at 2%. HWWS was observed only once before a feeding event (1%), twice after cleaning a child (9%), and twice after caregiver toilet use (40%). The combined implication of data from observing oral contact behavior in children and hand hygiene of caregivers suggests that caregiver hand hygiene prior to feeding events and after cleaning a child are priority interventions.

Chronic obstructive pulmonary disease (COPD) is associated with severe chronic inflammation that promotes irreversible tissue destruction. Moreover, the most broadly accepted cause of COPD is exposure to cigarette smoke. There is no effective cure and significantly, the mechanism behind the development and progression of this disease remains unknown. Our laboratory has demonstrated that Bruton’s tyrosine kinase (Btk) is a critical regulator of pro-inflammatory processes in the lungs and that Btk controls expression of matrix metalloproteinase-9 (MMP-9) in the alveolar compartment. For this study apolipoprotein E null (ApoE−/−) mice were exposed to SHS to facilitate study in a COPD/atherosclerosis comorbidity model. We applied two types of treatments, animals received either a pharmacological inhibitor of Btk or MMP-9 specific siRNA to minimize MMP-9 expression in endothelial cells or neutrophils. We have shown that these treatments had a protective effect in the lung. We have noted a decrease in alveolar changes related to SHS induced inflammation in treated animals. In summary, we are presenting a novel concept in the field of COPD, i.e., that Btk may be a new drug target for this disease. Moreover, cell specific targeting of MMP-9 may also benefit patients affected by this disease.

Published: January 2018

Metal salen/salophen complexes have been used as fluorescent probes for cell imaging with various metal centers. Herein we synthesized cryptand-type aluminum salophen complexes LAl3 and the corresponding mononuclear compound LAl. X-ray crystal diffraction verifies the cryptand-type structure of LAl3 with C3h symmetry. Both LAl3 and LAl show moderate green fluorescence with quantum yields of 0.17 and 0.05, respectively. The hydrophilic and cationic nature of these aluminum salophen complexes renders them enhanced cellular uptake. Both complexes are internalized into cells by energy-dependent pathways and they distribute in lysosomal organelles.

Published: January 2018

In this study, a precision motion stage, whose design utilizes a single shaft supported from the bottom by an air bearing and voice coil actuators in complementary double configuration, is evaluated for its dynamic properties, motion accuracy, and potential machining force response, through modal testing, laser interferometric metrology, and spectral analysis, respectively. Modal testing is carried out using two independent methods, which are both based on impact hammer testing. Results are compared with each other and with the predicted natural frequencies based on design calculations. Laser interferometry has been used with varying optics to measure the geometric errors of motion. Laser interferometry results are merged with measured servo errors, estimated thermal errors, and the predicted dynamic response to machining forces, to compile the error budget. Overall accuracy of the stage is calculated as peak-to-valley 5.7 μm with a 2.3 μm non-repeatable part. The accuracy measured is in line with design calculations which incorporated the accuracy grade of the encoder scale and the dimensional tolerances of structural components. The source of the non-repeatable errors remains mostly equivocal, as they fall in the range of random errors of measurement in laser interferometry like alterations of the laser wavelength due to air turbulence.

Terpenes are the largest and most diverse class of secondary metabolites in plants and play a very important role in plant adaptation to environment. 3-Hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) is a rate-limiting enzyme in the process of terpene biosynthesis in the cytosol. Previous study found the HMGR genes underwent gene expansion in Gossypium raimondii, but the characteristics and evolution of the HMGR gene family in Gossypium genus are unclear. In this study, genome-wide identification and comparative study of HMGR gene family were carried out in three Gossypium species with genome sequences, i.e., G. raimondii, Gossypium arboreum, and Gossypium hirsutum. In total, nine, nine and 18 HMGR genes were identified in G. raimondii, G. arboreum, and G. hirsutum, respectively. The results indicated that the HMGR genes underwent gene expansion and a unique gene cluster containing four HMGR genes was found in all the three Gossypium species. The phylogenetic analysis suggested that the expansion of HMGR genes had occurred in their common ancestor. There was a pseudogene that had a 10-bp deletion resulting in a frameshift mutation and could not be translated into functional proteins in G. arboreum and the A-subgenome of G. hirsutum. The expression profiles of the two pseudogenes showed that they had tissue-specific expression. Additionally, the expression pattern of the pseudogene in the A-subgenome of G. hirsutum was similar to its paralogous gene in the D-subgenome of G. hirsutum. Our results provide useful information for understanding cytosolic terpene biosynthesis in Gossypium species.

Published: January 2018

Indoor occupants’ positions are significant for smart home service systems, which usually consist of robot service(s), appliance control and other intelligent applications. In this paper, an innovative localization method is proposed for tracking humans’ position in indoor environments based on passive infrared (PIR) sensors using an accessibility map and an A-star algorithm, aiming at providing intelligent services. First the accessibility map reflecting the visiting habits of the occupants is established through the integral training with indoor environments and other prior knowledge. Then the PIR sensors, which placement depends on the training results in the accessibility map, get the rough location information. For more precise positioning, the A-start algorithm is used to refine the localization, fused with the accessibility map and the PIR sensor data. Experiments were conducted in a mock apartment testbed. The ground truth data was obtained from an Opti-track system. The results demonstrate that the proposed method is able to track persons in a smart home environment and provide a solution for home robot localization.
