ANALYSIS OF FUNCTIONAL REFERENCE ARCHITECTURE THROUGH AN INDUSTRY LENS

Abstract There is an inherent tension between functional descriptions of products and structural descriptions. Traditionally system architecture combine the two, by mapping system elements to functions. In this process fundamental decisions about the embodiment of a product are often taken without proper scrutiny. Axiomatic design advocates a zigzag between functional decomposition and system break down. While this approach makes sense for ab initio design these are rare and most products are developed incrementally. , This paper takes up the idea of a functional reference architecture. Conventional functional modelling advocates a hierarchical decomposition into sub function. By contrast FRAs decompose function into function chain, i.e., dependent sequences of sub function required to carry out an overall function. This allows the identification of common sub-functions in different chains, and thereby generates a lattice structure of functions rather than a tree. This enables a detailed but solution neutral description of the product. This concept has attracted interest in industry but does not have many tools and methods to develop FRA. The paper discusses some of the areas that require research

Além disso, implementamos um algoritmo genético para ponderação dos fatores de relevância. Resultados indicam uma melhor eficácia em comparação ao modelo utilizado como base.
Fullerene Black: Relationship between Catalytic Activity in n-alkanes Dehydrocyclization and Reactivity in Oxidation, Bromination and Hydrogenolysis

The reactivity of fullerene black in oxidation (by air oxygen or ions MnO 4 – or Cr 2 O 7 2– in solution), bromination (by Br 2 or (C 4 H 9 ) 4 NBr 3 ) and hydrogenolysis (without hydrogenation catalyst) are studied. The dehydrocyclization of n -alkanes over fullerene black is realized via the monofunctional mechanism, i.e. the dehydrogenation and cyclization stages proceed on the same catalytic center. The addition of alumina to the catalyst transforms dehydrocyclization mechanism to bifunctional one, when fullerene black acts as dehydrogenation agent. Reactivity studies and ESR spectroscopy data for initial and annealed fullerene black show the presence in fullerene black structure of both non-conjugated multiple and dangling bonds. Nonconjugated bonds determine catalytic activity and reactivity of fullerene black. They are localized in amorphous part of fullerene black. Technological aspects of fullerene black as alkanes dehydrocyclization catalyst are discussed.

EFFECT OF ESSENTIAL OIL OF PIMENTA RACEMOSA ON MICROFLORA AFFECTING QUALITY OF AFRICAN MUSTARD OBTAINED FROM FERMENTED SEEDS OF PARKIA BIGLOBOSA JACK. P. BR

The present study aims to investigate the effect of essential oil of Pimenta racemosa on the microflora affecting the marketable quality of African mustard obtained from fermented seeds of Parkia biglobosa. Essential oil of Pimenta racemosa was extracted by hydrodistillation. Different types of African mustard were produced by the modification of the traditional processing technology and the introduction of a step of essential oil adjunction during the process. Three different essential oil concentrations (1.0, 2.0 and 3.0 μLg-1) were investigated. Microbiological analyzes were performed in order to evaluate the quality of the African mustard produced. Results obtained revealed that the essential oil has inhibition property against the growth of total flora and fungi affecting marketable quality of African mustard during eight (08) days of storage, at the concentrations tested. However, bacterial growth was continuous and exponential in control samples. This supports the antimicrobial properties of the leaves of Pimenta racemosa and its traditional use as food ingredient. It is therefore suggested that further studies be carried out to isolate, purify and identify all active compounds present in all part of this plant.
Effects of the middle Holocene high sea‐level stand and climate on Amazonian mangroves

The high sea‐level stand during the mid‐Holocene is a benchmark in mangrove dynamics along the north‐east/south‐east coast of Brazil and provides a reference point for landward and seaward mangrove migrations corresponding to changes in relative sea level (RSL). However, evidence of the impacts associated with RSL fall on the northern Brazilian coast is scarce. Multi‐proxy data from the highest tidal flats of the Bragança Peninsula in northern Brazil revealed modern herbaceous areas were occupied by mangroves Rhizophora and Avicennia from ~6250 to ~5850 cal a bp, and only Avicennia between ~5850 and ~5000 cal a bp. The same tidal flats were vegetation‐free between ~5000 and ~4300 cal a bp. A combination of a high sea‐level stand (0.6 ± 0.1 m) at ~5000 cal a bp and a dry early–middle Holocene in the Amazon probably caused an increase in porewater salinity of tidal flats, which resulted in a mangrove succession from Rhizophora to Avicennia dominance. RSL fall accentuated this process, contributing to mangrove degradation between ~5000 and ~4300 cal a bp. RSL fall, and a wetter period over the past ~4300 cal a bp caused a mangrove migration from highest to lowest flats, followed by expansion of herbaceous vegetation on the highest flats.
A reconfigurable dual-band bandpass filter using memristive switches

In this paper, a reconfigurable dual-bandbandpass filter, usingmemristive switches, is proposed. The applied memristor is non-volatile and has low-power consumption, which could be potentially used as an RF switch. The dual-band bandpass filter is based on the dual-mode resonator with a memristor. The odd-mode and evenmode method is utilized to analyse the proposed reconfigurable filter. By loading a memristor to the optimum position of the resonator, the proposed dual-band bandpass filter’s responses can be switched. Thememristor is equivalent to a low-impedance resistor in ON state and ahigh-impedance capacitor inOFF state. The frequency responses of the proposed reconfigurable dual-band bandpass filter can be tuned by transforming the state of twomemristors. The alternative test method is used in this paper, and measured results are consistent with simulated results. ARTICLE HISTORY Received 5 January 2021 Accepted 17 July 2021
Properties of sustainable self-compacting concrete made with rice husk ash

Abstract Rice husk ash (RHA) is an agricultural by-product obtained from incineration of abundantly available rice husk (RH) which can be used as a substitute for cement. In this study, RHA up to 30% has been utilized as partial replacement of cement by weight along with fly ash as one of the components in self-compacting concrete (SCC). Experimental programs were conducted to evaluate the fresh properties of SCC. Strength properties i.e. compressive strength, splitting tensile strength, and durability properties such as sorptivity, water absorption & porosity, rapid chloride permeability test (RCPT), sulphate resistance were also evaluated up to the age of 365 days. It was found that the inclusion of RHA up to 15% had a positive effect on strength properties while durability properties improved significantly at all replacement levels of RHA. The compressive strength results were verified with microstructure analysis using scanning electron microscope (SEM). Moreover, it was observed that material cost savings of up to 18% can be achieved by using up to 30% of RHA along with reduction in the carbon footprint and embodied energy. Multi linear regression models were established to predict the strength and durability properties at different curing ages and replacement levels of RHA.
Demons of the mind: The ‘psy’ sciences and film in the long 1960s

This introduction provides context for a collection of articles that came out of a research symposium held at the Science Museum's Dana Research Centre in 2018 for the ‘Demons of Mind: the Interactions of the ‘Psy’ Sciences and Cinema in the Sixties' project. Across a range of events and research outputs, Demons of the Mind sought to map the multifarious interventions and influences of the ‘psy’ sciences (psychology, psychiatry, and psychoanalysis) on film culture in the long 1960s. The articles that follow discuss, in order: critical engagement with theories of child development in 1960s British science fiction; the ‘horrors’ of contemporary psychiatry and neuroscience portrayed in the Hollywood blockbuster The Exorcist (1973); British social realist filmmakers' alliances with proponents of ‘anti-psychiatry’; experimental filmmaker Jane Arden's coalescence of radical psychiatry and radical feminist techniques in her ‘psychodrama’ The Other Side of the Underneath (1973); and the deployment of film technologies by ‘psy’ professionals during the post-war period to capture and interpret mother-infant interaction.
The Brain’s Structural Differences in Peripheral Neuropathic Pain: A Comparison Study Between Postherpetic Neuralgia and Lower Back Pain

The purpose is to explore the brain’s structural difference in local morphology and between-region networks between two types of peripheral neuropathic pain (PNP): postherpetic neuralgia (PHN) and lower back pain (LBP). A total of 54 participants including 38 LBP and 16 PHN patients were enrolled. The average pain scores were 7.6 and 7.5 for LBP and PHN. High-resolution structural T1 weighted images were obtained. Both grey matter volume (GMV) and morphological connectivity (MC) were extracted. An independent two-sample t-test with false discovery rate (FDR) correction was used to identify the brain regions where LBP and PHN patients showed significant GMV difference. Next, we explored the differences of MC network between LBP and PHN patients and detected the group differences in network properties by using the two-sample t-test and FDR correction. Compared with PHN, LBP patients had significantly larger GMV in temporal gyrus, insula and fusiform gyrus (p < 0.05). The LBP cohort had significantly stronger MC in the connection between right precuneus and left opercular part of inferior frontal gyrus (p < 0.05). LBP patients had significantly stronger degree in left anterior cingulate gyrus and left rectus gyrus (p < 0.05) while had significantly weaker degree than PHN patients in left orbital part of middle frontal gyrus, left supplementary motor area and left superior parietal lobule (p < 0.05). LBP and PHN patients had significant differences in the brain’s GMV, MC, and network properties, which implies that different PNPs have different neural mechanisms concerning pain modulation.
Marketing Fortified Rice: Effects of Aspirational Messaging and Credibility of Health Claims

Author(s): Chowdhury, Reajul; Crost, Benjamin; Hoffmann, Vivian | Abstract: Studies assessing the impact of information on uptake of preventive health products among the poor have shown mixed results, and little is known about what type of messages are most effective. Drawing on insights from the literature on marketing and consumer behavior, we argue that messages which position a product as aspirational or establish the credibility of its health benefits can increase consumer demand for the product. We test the individual and joint impacts of such messages through a field experiment eliciting willingness to pay for fortified rice in Chandpur District, Bangladesh. We find that the combination of these approaches increases the proportion of participants willing to pay a premium at least equal to the cost of fortification by 18 percentage points. In sharp contrast to the existing literature on welfare stigma, we also show that awareness of free distribution of fortified rice through government programs does not negatively affect consumer demand, but rather appears to lend credibility to health claims about the product.
Rotation Correction Method Using Depth-Value Symmetry of Human Skeletal Joints for Single RGB-D Camera System

Most red-green-blue and depth (RGB-D) motion-recognition technologies employ both depth and RGB cameras to recognize a user's body. However, motionrecognition solutions using a single RGB-D camera struggle with rotation recognition depending on the device-user distance and field-of-view. This paper proposes a nearreal-time rotational-coordinate-correction method that rectifies a depth error unique Microsoft Kinect by using the symmetry of the depth coordinates of the human body. The proposed method is most effective within 2 m, a key range in which the unique depth error of Kinect occurs, and is anticipated to be utilized in applications requiring low cost and fast installation. It could also be useful in areas such as media art that involve unspecified users because it does not require a learning phase. Experimental results indicate that the proposed method has an accuracy of 85.38%, which is approximately 12% higher than that of the reference installation method.
Association of Bacteria Species with Positive Predictive Value of Bacteria Isolated from Cerebrospinal Fluid Cultures: A Retrospective Cohort Study

Background: Previous studies discuss the positive predictive value through whether the bacteria are coagulase-negative staphylococci. The view may need to be updated. The aim was to evaluate the positive predictive value of different bacteria species isolated from cerebrospinal fluid cultures and discuss the rationality to view coagulase-negative staphylococci as a group.Methods: This retrospective cohort study recruit all adults with positive cerebrospinal fluid cultures sampled by lumbar puncture 2012-2020 in the Department of Neurosurgery. The exposure was bacteria species, and the outcome was positive predictive value. An episode was defined as a patient with one bacteria. When episodes with a bacteria species reached five, the bacteria species was analyzed specifically. The positive predictive value was defined as the incidence of isolated-bacteria-related infected episodes. The isolated-bacteria-related infected episode was defined as the patient was with clinical features of bacterial meningitis, and the improvement was related to sensitive antibacterial agents. Then the differences of the positive predictive value of different bacteria in all specific bacteria species, coagulase-negative staphylococci, and non-coagulase-negative staphylococci bacteria were calculated, respectively. The results were statistically significant when P-value <. 05.Results: 1180 episodes from 1133 patients with 79 bacteria were studied; the positive predictive value was 54.3%. The bacteria included 67 bacteria species, ten bacteria genus, viridans streptococci, and unclassified coagulase-negative staphylococci. Twenty-four specific bacteria species were analyzed. The range of positive predictive values of them was 29.4%-100.0% (P<.0001). The positive predictive value for Enterobacter aerogenes, Pseudomonas aeruginosa, Enterobacter cloacae, and Klebsiella oxytoca was the highest, while the positive predictive value for Staphylococcus cohnii was the lowest. Moreover, 767 (65.0%) were with coagulase-negative staphylococci, the positive predictive value was 46.4%, and the range was 29.4%-85.7% (P=.0020); 413 (35.0%) were with non-coagulase-negative staphylococci bacteria, the positive predictive value was 69.0%, and the range was 40.0%-100.0% (P<.0001). Conclusions: This study suggests that the positive predictive value of different bacteria species is different. It is more reasonable to discuss the positive predictive value of bacteria isolated from cerebrospinal fluid cultures through the bacteria species rather than whether they are coagulase-negative staphylococci.Trial registration: This is a retrospective study without interventions on participants.
Anti-Oxidant Activity of Enalapril maleate in Hypercholesterolemic Rabbits

The present study was to evaluate the anti-oxidant activity of Enalapril maleate in hypercholesterolemic rabbits,which developed atherosclerosis. Enalapril maleate is a class of Angiotensin Converting Enzyme Inhibitors.Normal healthy rabbits of either sex were divided in three groups. Each group contained twenty–five animals, all of which received commercial diet and water ad-libitum throughout the experimental period. The experiment was carried for a period of sixteen weeks.Group I animals received normal saline (5 ml/kg P.O) for a period of sixteen weeks. Group II received 500 mg cholesterol in 5 ml starch mucilage P.O daily for 16 weeks- hypercholesterolemic group. Group III received 500 mg cholesterol suspended in 5 ml starch mucilage and Enalapril maleate (10 mg/kg b.w PO daily) for 16 weeks. Various biochemical estimations like total serum cholesterol, serum HDL cholesterol levels, TBARS (Thiobarbituric acid reactive substances), glutathione, catalase were estimated. Results showed that decrease in total serum cholesterol levels, TBARS levels and increase in HDL cholesterol levels can play a part in anti-atherosclerotic action of Enalapril maleate.Catalase and glutathione which detoxify free radicals are not involved in the anti-atherosclerotic effect of the drug.
A New Converter for Non-Isolated PV Systems

A new converter for the non-isolated PV (photovoltaic) system is presented in this paper. It has the advantage that the input terminal of the proposed converter is connected to the output negative terminal. In this way, the parasitic capacitance is bypassed to eliminate the undesirable leakage current. The proposed converter can achieve the step-up voltage with four switches only. Aside from that, the carried-based modulation is used, and the control structure is simple. The article analyzes the working modes and control strategy of the proposed converter. In addition, a comparative analysis is provided. The feasibility of the proposed converter under different working modes is verified by simulation. Finally, the digital control prototype with DSP plus FPGA is established and the experimental tests are carried out. The experimental results verify the effectiveness of the proposed converter.
Delineating Source Contributions to Stream Dissolved Organic Matter Composition Under Baseflow Conditions in Forested Headwater Catchments

Dissolved organic matter (DOM) composition in streams reflects the dynamic interplay between DOM sources, mobilization mechanisms, and biogeochemical transformations within soils and receiving water bodies. The information regarding DOM sources being mobilized during baseflow can improve our ability to predict hydrological and biogeochemical responses to environmental changes, with implications for catchment management strategies. The objective of this study was to characterize the spatial changes in DOM composition along a headwater stream in a small mountainous catchment during baseflow and to link the findings in‐stream with possible DOM sources in the catchment. DOM was monitored over 1.5 years at three sites in the Große Ohe catchment (Bavarian Forest National Park, Southeast Germany) which strongly varied in slope between upper and lower part of the catchment, using UV‐Vis absorption indicators of aromaticity (SUVA) and molecular weight (E2:E3) from high‐frequency probe measurements. Additionally, discrete samples were collected and analyzed by ultrahigh‐resolution Fourier transform ion cyclotron resonance mass spectrometry (FT‐ICR‐MS). At baseflow conditions, dissolved organic carbon (DOC) concentrations, a proxy of DOM amount, ranged from 1.5 to 4.7 mg L−1, but were similar along the stream. However, DOM quality exhibited clear spatial patterns, with overall high aromatic and low molecular weight DOM in the lower part of the catchment, which has a higher proportion of hydromorphic soils. Moreover, molecular data revealed that oxygen‐rich, aromatic compounds increased in their abundance at high DOC concentrations in both the steep upper and the flatter lower part of the catchment, with also additional input of oxygen‐depleted aromatic compounds identified in the lower part. In contrast, nitrogen‐rich aliphatic compounds were negatively correlated with DOC concentration, indicating a higher contribution of deep groundwater at low DOC concentrations.
Neural Substrates of Aphasia in Acute Left Hemispheric Stroke Using Voxel-Based Lesion-symptom Brain Mapping

It is unclear how these brain lesions fit into the language processing in acute stroke. In this study, we aimed to investigate the neuroanatomical lesion related to language processing in acute stage of stroke patients using voxel-based lesion-symptom mapping (VLSM). 73 acute first-ever post-stroke patients were enrolled in this retrospective study, who had undertaken brain magnetic resonance imaging (MRI) and Korean version of the Western Aphasia Test within 1 month from onset. Each voxel was compared with aphasia quotient and subtest scores as dependent variables using VLSM. The aphasia group showed significantly much more involvement of extra-nuclear area, insula, inferior frontal gyrus and superior temporal gyrus compared to non-aphasia group. The deficit of spontaneous speech domain was associated with the inferior parietal lobule, inferior and middle frontal gyrus and insula. The insular cortex, inferior parietal lobule, inferior frontal gyrus, middle frontal gyrus and superior temporal gyrus were related to deficit of comprehension. The inferior parietal lobule, insula, precentral gyrus, inferior frontal gyrus were related to the deficit of repetition. The deficit of naming was related to inferior parietal lobule, insula and inferior frontal gyrus. In conclusion, VLSM from early MRI imaging study after stroke may be useful to understand the language process network and establish early rehabilitation strategies after stroke.
