Diffusion tensor imaging in assessment of demyelinating diseases of central nervous system

Background: Conventional MR plays an important role in detection of demyelinating lesions. Involvement of the lesion core, perilesional region and normally appearing white matter (NAWM) cannot be quantified using routine T2/FLAIR sequences. DTI is an important tool in assessment of anisotropy in affected and apparently normal region of brain. 3D Tractography maps are useful in showing white matter fibre loss. Aim was the assessment of white matter damage and neuroaxonal loss using DTI in demyelinating lesions Methods: Cross sectional observational study including clinically suspected 30 patients of demyelinating disease. Patients were studied in 3Tesla Siemens Skyra MRI scanner with phased array coils. T1w, T2w, FLAIR, DWI, DTI, post contrast T1w images were included and FA, ADC, Tractography maps were generated. ANOVA test and BONFERONI analysis were used. Results: We found mean FA of core lesion was 0.307±0.06, of perilesional region 0.444±0.03 and NAWM 0.567±0.06. The mean ADC value of core of the lesion was 1.24×10-3mm/sec±0.11×10-3mm/sec, perilesional region 1.16×10-6mm/sec ±0.1×10-3mm/sec and NAWM 1.04×10-3mm/sec±0.06×10-3mm/sec. Conclusions: DTI is a useful MR technique that allows quantification of extent of demyelination in the white matter measuring FA and ADC values. The FA values which denote diffusivity and directionality are more reliable marker of demyelination compared to ADC values. DTI Tractography shows white matter tract disruption which may play role in assessing clinical outcome of patients.

The development of supply chain risk management over time: revisiting Ericsson

PurposeThis invited article explores current developments in supply chain risk management (SCRM) practices by revisiting the classical case of Ericsson (Norrman and Jansson, 2004) after 15 years, and updating its case description and analysis of its organizational structure, processes and tools for SCRM.Design/methodology/approachAn exploratory case study is conducted with a longitudinal focus, aiming to understand both proactive and reactive SCRM practices using a holistic perspective of a real-life example.FindingsThe study demonstrates how Ericsson's SCRM practices have developed, indicating that improved functional capabilities are increasingly combined across silos and leveraged by formalized learning processes. Important enablers are IT capabilities, a fine-grained and cross-functional organization, and a focus on monitoring and compliance. Major developments in SCRM are often triggered by incidents, but also by requirements from external stakeholders and new corporate leaders actively focusing on SCRM and related activities.Research limitations/implicationsRelevant areas for future research are proposed, thereby increasing the knowledge of how companies can develop SCRM practices and capabilities further.Practical implicationsBeing one of few in-depth holistic case studies of SCRM, decision-makers can learn about many practices and tools. Of special interest is the detailed description of how Ericsson reactively responded to the Fukushima incident (2011), and how it proactively engaged in monitoring and assessment activities. It is also exemplified how SCRM practices could continuously be developed to make them “stick” to the organization, even in stable times.Originality/valueThis is one of the first case studies to delve deeper into the development of SCRM practices through taking a longitudinal approach.
Motivations for Participation and Cross-culture Adjustment of Taiwanese Working Holiday Makers in Australia

This study aims to discuss working tourists' experiences, which include the motives before departure, cross-culture shock and adaption during the journey, and reflection after returning to Taiwan. Qualitative in-depth interviews were provided by 28 participants recruited through snowball sampling. We found that participation in a working holiday could be driven by three types of motivation: the influences of a reference group, high pay, and policy leniency. The transcripts of participants’ interviews allowed the development of the two themes of sociocultural and psychological adjustment. Working holiday participants believed they could achieve several benefits, including improving their language skills, enhancing their ability to deal with people and situations, training their decision-making skills, and changing their attitudes towards life.
Evaluation of the insecticidal potential of leaf extracts of Anadenanthera colubrina var. cebil (Griseb) Altschul against Tetranychus urticae Koch and Sitophilus zeamais Mots

The deterioration and degradation of crops by insects causes economic losses of several billion dollars and affects food security. Sitophilus zeamais and Tetranychus urticae are two economically important species of agricultural crops around the world. The high toxicity of synthetic insecticides and the development of insect resistance to currently used chemicals stimulate the investigation of plant-derived insecticides as new alternatives for pest control. The insecticidal properties of secondary metabolites have been recognized, and have been confirmed scientifically in the last decades. The extract in cyclohexane (Ch) and ethyl acetate (Ea) of the leaves of Anadenanthera colubrina var. cebil collected in the dry and rainy seasons were evaluated for the survival and nutritional physiology of S. zeamais (maize weevil) and for the acaricidal effect front T. urticae (two-spotted spider). All extracts induced mortality of S. zeamais; however, only cyclohexane dry season (Chd) and ethyl acetate in the rainy season (Ear) caused significant mortality (p <0.05), more than 50%, promoting physiological damage to insects in all concentrations tested. In the mortality tests with the spider mite, extracts Chd and Ear showed an LC50 of 52.75 and 156.42 mg.mL-1. Still, in the same test, it can be observed that oviposition was also susceptible to extracts. Therefore, the extracts of A. colubrina are a source of compounds capable of interfering with and impairing the metabolism of the two studied pests.
An Evaluation of College Students’ Healthy Food Consumption Behaviors

ABSTRACT The purpose of this research is to investigate factors influencing college students’ healthy eating behaviors. The study was conducted in the campus dining services of a Midwest university in the U.S. using paper surveys developed based on related literature review. A convenience sample of 321 college students participated in the study (52.5% male). Researchers collected dining receipts from each participant to measure students’ calorie consumption behaviors from February 2018 to May 2018. Results showed that attitudes toward healthy eating (3.84 ± 0.62, p < .001), body image (3.44 ± 0.82, p<.001), social influences of healthy eating (3.63 ± 0.85, p < .001), and guilt level of consuming unhealthy food (2.97 ± 1.03, p < .05) had significant positive relationships with healthy food consumption intention. Furthermore, attitudes toward healthy eating (3.84 ± 0.62, p < .001), social influences of healthy eating (3.63 ± 0.85, p< .01), hunger level (3.44 ± 1.65, p< .001), and guilt level of consuming unhealthy food (2.97 ± 1.03, p< .05) had significant negative relationships with healthy food eating behaviors (719.43 ± 387.73). Meanwhile, intention (t = −3.49, p < .001) plays a partial mediating role between attitude toward healthy diet and healthy eating behaviors. This study also provides some recommendations for improving the college diet based on the results.
Solving the Stochastic Generation and Transmission Capacity Planning Problem Applied to Large-Scale Power Systems Using Generalized Shift-Factors

In this study, we successfully develop the transmission planning problem of large-scale power systems based on generalized shift-factors. These distribution factors produce a reduced solution space which does not need the voltage bus angles to model new transmission investments. The introduced formulation copes with the stochastic generation and transmission capacity expansion planning problem modeling the operational problem using a 24-hourly load behaviour. Results show that this formulation achieves an important reduction of decision variables and constraints in comparison with the classical disjunctive transmission planning methodology known as the Big M formulation without sacrificing optimality. We test both the introduced and the Big M formulations to find out convergence and time performance using a commercial solver. Finally, several test power systems and extensive computational experiments are conducted to assess the capacity planning methodology. Solving deterministic and stochastic problems, we demonstrate a prominent reduction in the solver simulation time especially with large-scale power systems.
Diophantine equations connected to the Komornik polynomials

We investigate the power and polynomial values of the polynomials Pn(X) = ∏ n k=0 ( X2·3 k − X3 k − 1 ) for n ∈ N. We prove various ineffective and effective finiteness results. In the case 0 ≤ n ≤ 3, we determine all pairs x, y of integers such that Pn(x) = y2 or Pn(x) = y3.
Robust Decadal Hydroclimate Predictions for Northern Italy Based on a Twofold Statistical Approach

The Mediterranean area belongs to the regions most exposed to hydroclimatic changes, with a likely increase in frequency and duration of droughts in the last decades. However, many climate records like, e.g., North Italian precipitation and river discharge records, indicate that significant decadal variability is often superposed or even dominates long-term hydrological trends. The capability to accurately predict such decadal changes is, therefore, of utmost environmental and social importance. Here, we present a twofold decadal forecast of Po River (Northern Italy) discharge obtained with a statistical approach consisting of the separate application and cross-validation of autoregressive models and neural networks. Both methods are applied to each significant variability component extracted from the raw discharge time series using Singular Spectrum Analysis, and the final forecast is obtained by merging the predictions of the individual components. The obtained 25-year forecasts robustly indicate a prominent dry period in the late 2020s/early 2030s. Our prediction provides information of great value for hydrological management, and a target for current and future near-term numerical hydrological predictions.
Multiresolution Speech Enhancement Based on Proposed Circular Nested Microphone Array in Combination with Sub-Band Affine Projection Algorithm

Speech enhancement is one of the most important fields in audio and speech signal processing. The speech enhancement methods are divided into the single and multi-channel algorithms. The multi-channel methods increase the speech enhancement performance by providing more information with the use of more microphones. In addition, spatial aliasing is one of the destructive factors in speech enhancement strategies. In this article, we first propose a uniform circular nested microphone array (CNMA) for data recording. The microphone array increases the accuracy of the speech processing methods by increasing the information. Moreover, the proposed nested structure eliminates the spatial aliasing between microphone signals. The circular shape in the proposed nested microphone array implements the speech enhancement algorithm with the same probability for the speakers in all directions. In addition, the speech signal information is different in frequency bands, where the sub-band processing is proposed by the use of the analysis filter bank. The frequency resolution is increased in low frequency components by implementing the proposed filter bank. Then, the affine projection algorithm (APA) is implemented as an adaptive filter on sub-bands that were obtained by the proposed nested microphone array and analysis filter bank. This algorithm adaptively enhances the noisy speech signal. Next, the synthesis filters are implemented for reconstructing the enhanced speech signal. The proposed circular nested microphone array in combination with the sub-band affine projection algorithm (CNMA-SBAPA) is compared with the least mean square (LMS), recursive least square (RLS), traditional APA, distributed multichannel Wiener filter (DB-MWF), and multichannel nonnegative matrix factorization-minimum variance distortionless response (MNMF-MVDR) in terms of the segmental signal-to-noise ratio (SegSNR), perceptual evaluation of speech quality (PESQ), mean opinion score (MOS), short-time objective intelligibility (STOI), and speed of convergence on real and simulated data for white and colored noises. In all scenarios, the proposed method has high accuracy at different levels and noise types by Appl. Sci. 2020, 10, 3955; doi:10.3390/app10113955 www.mdpi. com/journal/applsci Appl.

Statutory placement experiences of final year students on a BSc (Hons) social work program in England

ABSTRACT Local authority social work departments in England have been facing challenges from a number of different areas for several years. The onset of austerity in 2008 resulted in funding reductions and constraints, many authorities have been deemed to be ‘inadequate’ or ‘in need of improvement’ by Ofsted, their inspectorate, and working conditions for practitioners have been found to be poor. It is against this backdrop that social work students on qualifying programs undertake their final year statutory placement. This research investigates the experiences of final year social work students on a BSc (Hons) Social Work program in England. Focus groups and interviews were used to explore the experiences of 18 students placed within both Adults’ and Children’s Services in three local authorities. Data were analysed thematically and revealed commonalities and differences in experience. Differences between services were apparent with students from Children’s Services focusing upon local authority processes whilst Adults’ Services gave greater consideration to supervision and support. The areas of motivation and values, awareness of others, power and process also emerged as significant themes.
Simulation Method of Borehole Trajectory Based on Vector Similarity

For the well planning stage, the application of the designed borehole trajectory (DBT) predicts that the torque and drag is low, and it is impossible to accurately analyze the difficulty and risk of drilling construction. This paper proposes a method for comparing and selecting borehole trajectory control parameters based on the vector cosine similarity. The database for borehole trajectories has been established, and two vectors were designed to represent the control state of the actual borehole trajectory (ABT) and the simulation position of the simulated borehole trajectory (SBT), respectively, and the similarities of them were used as the reference standard for simulating the behavior of engineers to determine the control parameters. Random selection of control parameters was set to further simulate the behavior of the engineer. The feasibility of the method was evaluated by using the control deviation and torque and prediction deviation. The case well experiment results show that the control deviations of the SBT and the ABT relative to the DBT are close, and the fluctuation law is similar. In rotary drilling conditions, the torque calculated using SBT is slightly higher than the actual drilling torque, and the maximum deviation is less than 10%. In tripping out condition, the hook loads are slightly higher, and the maximum deviation is less than 9%. In additional operating conditions, the hook loads calculated by the SBT are the same as the actual hook loads, and the maximum deviation is less than 4%. This work provides a feasible method to simulate ABT in the well planning stage and enhances the reliability of the predicted torque and drag results.
The Distribution of Planktivorous Damselfishes (Pomacentridae) on the Great Barrier Reef and the Relative Influences of Habitat and Predation

Planktivorous damselfishes (Pomacentridae) are diverse and abundant on the Great Barrier Reef (GBR), are important prey for commercially harvested coral trout (Plectropomus spp.) and their feeding mode plays a central role in transferring energy from the plankton to the reef. However, little is known about their distribution patterns throughout the GBR and how those patterns are influenced by predators and habitat despite increasing pressures on both. Here we quantify the distribution and abundance of GBR planktivorous damselfishes, then examine the role of coral trout and habitat in shaping their assemblages. The assemblage structure of planktivorous damselfishes varied across the continental shelf, yet their total abundances varied sub-regionally, dependent on differences in coral habitat. Latitudinal patterns were relatively weak. Damselfish assemblages generally retained characteristics of their sub-regional setting over 20 years and assemblage degradation was only associated with major coral losses. Damselfish numbers were not negatively influenced by top-down control from coral trout. Instead, numbers of coral trout and damselfishes were both positively associated with coral habitat and each other. Our findings suggest that a complexity of factors and interactions shape reef fish assemblages and reinforce the fundamental importance of coral as the foundation of healthy reef communities.
Tantangan Pondok Pesantren Menuju Lembaga Pendidikan Islam yang Akuntabel

Islamic boarding school is one of the oldest Islamic education institutions in Indonesia. The majority of Islamic boarding schools in Indonesia are foundations. As an institution or non-profit entity, Islamic boarding schools also need to do an institutional transformation so that it can continue to grow and be trusted by stakeholders. So far, the financial reporting of Islamic boarding schools does not have standardization. So that each boarding school has a different form of financial reporting. In the end, Bank Indonesia and the Indonesian Institute of Accountants (IAI) developed the Pesantren Accounting Guidelines (PAP). Pesantren Accounting Guidelines are one of the programs in the development of pesantren economic independence. This article aims to describe the challenges faced by Islamic boarding schools in achieving accountable Islamic education institutions. Based on the literature review, there are three challenges in Islamic boarding schools in order to become an accountable Islamic educational institution, namely the boarding school human resources in the field of accounting, cooperation between related institutions and the use of technology. Islamic boarding schools must increase or increase competent human resources in the fields of accounting and financial reporting. Collaboration between related institutions can help boarding schools in increasing accountability. The provision of technology and the procurement of a type of software or application can make it easier for Islamic boarding school human resources to prepare financial reports in accordance with financial accounting standards (SAK), in this case in accordance with Islamic Boarding School Accounting Guidelines.Keywords: Islamic Boarding School, Accountable, Islamic Boarding School AccountingJEL Classification Codes: L31, Z12, Z18
Impacts of Paraffin Wax and Propolis on Controlling Crown Rot Disease and Maintaining Postharvest Quality of Banana

Crown rot disease is a major cause of losses during transportation, storage, and marketing of banana. In this study, the effects of paraffin wax, propolis extract and their combination on controlling crown rot disease and maintaining the quality of banana cv. Hom Thong were investigated. Crown of banana fruit were coated with 50% propolis, 100% paraffin wax and 100% paraffin wax combined with 50% propolis. Banana crown treated with 250 ppm prochloraz and non-coated fruit were used as the controls. All treatments were packed in corrugated box, stored at 13°C for 21 days (simulation for the transportation and storage) and then moved to ambient temperature for 6 days (simulation for the retail market). Results found that coating with paraffin wax combined with propolis showed the efficacy on controlling crown rot disease as same as using 250 ppm prochloraz. While coating with paraffin wax or propolis alone showed the incidence and severity of disease similar to non-coated fruit. Beside, coating with paraffin wax alone or combined treatment of paraffin wax and propolis could maintain some plant resistant mechanisms such as the content of total phenolic and the activity of phenylalanine ammonia lyase (PAL) in the crown of banana. For the quality of banana showed that coating with paraffin wax alone or the combination of paraffin wax and propolis were able to reduce weight loss, maintain firmness and color change of banana crown, and it did not affect to color change of peel and firmness of banana fruit.
