Bioprospecting microalgae harnessed from the coastal belt of Mangalore, India as prospective nutraceutical and biofuel candidates

ABSTRACT The nature of global dietary supplements is transitioning from animal derivatives to plant based. Industries around the world are seeking vegan alternatives to animal-derived supplements. The microalgal industry is expected to undergo a market boom in the current decade. Microalgal supplements (power based and extracts) as well as microalgal fuels are expected to show a significant increase in market value. Microalgae are an under-utilized source of high-value products. They are rich reservoirs of multiple compounds capable of enhancing immunity, fortifying nutritional diets and improving cardiovascular health. Microalgae are also high lipid producing organisms, which make them viable candidates in the global search for energy alternatives. However, the inability to translate in vitro results onto the industrial scale is a major drawback of the microalgal research landscape. It is therefore, vital to find a robust microalgal species capable of producing a feasible quantity of high-value compounds. This paper investigates the potential of four microalgae sourced from the coastal town of Mangalore, India as candidates for nutraceutical industries and the clean energy industry. Desmodesmus komareikii (MK990101) was found to be rich in total lipid, while the three Chlorella species were found to be relatively richer in total protein yields. Chlorella thermophila (MN006612) is capable of yielding harvests up to nearly 280 tonnes/acre/year. Chlorella thermophila (MN006612) yielded the highest amount of both mono and polyunsaturated fatty acids. The fatty acid profiles of Chlorella thermophila (MN006612), Chlorella vulgaris (MN252517-18) and Chlorella sorokiniana (MN011568) can be explored as an alternative edible oil. Desmodesmus komareikii (MK990101) yielded the highest amount of saturated fatty acids, which are used in the production of clean and quality biofuels.
Combining a differential global positioning system and double electric compass to improve multi-path error correction for a high-precision agricultural robotic vehicle

This work has addressed the improving of the multi-path error in positioning systems by coupling a differential global positioning system (DGPS) and double electric compass (DEC) in the navigation system of an orchard robotic vehicle. A novel corrective algorithm model was applied to predicting the positioning coordinates during vehicle movement. The model manipulates a combination of data from both the DEC and the DGPS when the DGPS receiver is in problematic conditions in which the horizontal dilution of precision (HDOP) is higher than three and the number of satellites is fewer than six. The constructed corrective algorithm model, the DEC and the DGPS together form a combined DGPS-DEC system that is inexpensive and of high-precision fitting for a vehicle-guiding instrument. In a field test in an outdoor environment with sections of tree shade in the guiding path, the combined DGPS-DEC positioning system effectively improved the reliability of positioning by correcting the DGPS multi-path error precisely to within 20 cm. By applying a mini-sprayer, further agricultural applications were feasible. In summary, the combined DGPS-DEC positioning system can obtain the correct position of a vehicle in real time for agricultural applications.

This model has been selected to match closely with a physical robot currently in construction, for the purpose of furthering the state-of-the-art in legged machines which locomote efficiently based on passive-dynamic principles. A novel actuator called the Variable Stiffness Series Elastic Actuator (VSSEA) is also introduced. Its design and advantages are briefly discussed.
A SPICE model of a 2-phase permanent magnet step motor

A SPICE model of a two-phase, permanent magnet, step-motor is presented by the authors. It is capable of predicting, with reasonable accuracy, the electrical and electromechanical dynamics associated with a step-motor system. Central to the modeling process is the use of reference-frame theory to eliminate the time-varying inductances associated with the stator voltage equations, and the SPICE realization of a voltage-control oscillator as a means of synthesizing the sine cosine functions. The resulting step-motor model is shown to be able to predict both single-step and fixed-stepping-rate failure modes of a typical step-motor system. <<ETX>>
A Guide Book for Making a Reservation at the Reception of a Hotel

Tampereen ammattikorkeakoulu Tampere University of Applied Sciences Degree Programme in Tourism LAMBERG OLLI: A Guide Book for Making a Reservation at the Reception of a Hotel Bachelor's thesis 26 pages, appendix 35 pages November 2013 The aim for this bachelor's thesis was to produce a guide book for making a reservation to be used at the reception of Original Sokos Hotel Ilves. The need for such a guide book was introduced by the hotel itself as there was no guide book of this kind specifically designed for Original Sokos Hotel Ilves. There was only a very large and rather impractical chain-level guide book for the system used in the front desk computers which had not been in active use by the reception staff. The main element of the created guide book was practicality. The guide book created for the hotel covers all the most commonly used reservation types and it has very specific instructions and visuals so that knowing beforehand the computer program that is being used is not necessarily required. The guide book also has a concise presentation of the room types in the hotel. In addition, the most important and most often used side functions in the computer program were scrutinized when they were connected with making the reservation. The guide book can be found in the appendix of this thesis to respect the privacy of the company. The author used his own work experience at the front desk, as well as the experience of his colleagues, when going through the most important factors of the guide book. The wishes of the management of the hotel were carefully enquired and updated during the process. Theoretical framework for the thesis consists of theories and concepts of good service and its importance in bringing customer value. The guide book will be used at the receptions of Original Sokos Hotel Ilves and other Sokos Hotels in Tampere. It is especially aimed for trainees and new staff members who would then gain the needed information effectively and consistently. It is of major importance that the guide book is updated whenever needed due to changes in working environment, such as when new reservation types are introduced or the products (hotel rooms) are renewed.
PIV VERIFICATION OF GREENHOUSE VENTILATION AIR FLOWS TO EVALUATE CFD ACCURACY

A computational fluid dynamics (CFD) model was developed to investigate the natural ventilation of greenhouses. Before investigating its accuracy, a wind tunnel and particle image velocimetry (PIV) test was initially conducted to find the best experimental conditions and improve the PIV accuracy. After many trials of the PIV tests, good results were obtained in the PIV accuracy test, and the errors were shown to be mostly in the . 2.1% range, with a maximum of 5.4%. A single-span, wide-span greenhouse, one of the most popular types of multi-span greenhouses in Korea, was used to get qualitative and quantitative airflow distribution in the greenhouse using PIV and CFD. To improve the CFD accuracy, the PIV- and CFD-computed airflows in the greenhouse were compared, particularly on the distribution, local air velocity, and turbulent intensity in the greenhouse. The quality of the mesh density and the design of the boundary condition, especially that of the wind velocity and turbulence profiles, were found to be very important for getting accurate results. Assuming the PIV results were accurate, the most accurate CFD results were obtained when using renormalization-group (RNG) k-. and Reynolds stress turbulence numerical models. The errors of the CFD-computed air velocity when using the RNG k-. and Reynolds stress models were -7.9% and -7.6%, respectively. However, the average errors of turbulent intensity when the RNG k-. and Reynolds stress turbulence numerical models were used were -37.5% and -43.2%, respectively.
Job Design, Change and Technology In Relation To Job Evaluation - A Reflective View

This paper intends to focus on the important issues and questions related to job design in the context of job evaluation. In particular: can job design be influenced by the work culture of an organization? What are the main situations that call for job design and / or redesign? How / when does job design interact and deal with the changes in job content? How does job design seek to combine the dynamic nature of work in a high-technology society? How do change, technological development and growth in an organization"s size, affect job demand / job content, the organization"s pay system and the job holder? How does job design itself demonstrate that it is a dynamic process, a task-focused process designed to make sure that jobs are structured / restructured / reorganized / right sized (including downsizing) to fit a task rather than the task performer (i.e. where the job- holder is (recruited) to fit the job, but not vice versa). In so doing, can job design make an organization"s performance more effective and more efficient, and if so how? Can the combination of job design and job evaluation processes accentuate job evaluation flexibility and responsiveness? Here lies the challenge. For job evaluation must be able to be adaptable, responsive and capable of satisfying all the new developments that result from job design or redesign, rather than for it to be seen as a rigid or inflexible system.

A systemic perspective for mass customization: an approach for product lines definition

Nowadays, the customer-oriented market and the stress on performances lead a lot of enterprises to adopt the Mass Customization (MC) (Davis 1987) strategy as identified in (Tseng and Jiao 2001). Ideally MC is a business approach that provides a product customization capability like an engineer-to-order organization (ETO - the product is designed at each order entry), preserving the mass production efficiency. In this paper, we cope with the formalization of the link between customer needs and the customized product variant that can be configured starting from them. The aim is to propose a way to build this link for formalizing the product variety in the customer domain. This paper is based on industrial cases of Trane, a multinational company that develops, manufactures and commercializes air-handling systems.
Small-signal and temperature noise model for MOSFETs

The present CMOS technology provides n-channel MOSFETs with a transit frequency beyond 30 GHz, which are attractive for RF integrated circuits, e.g., low-noise amplifiers. This paper presents an improved deembedding procedure for extraction of parasitic elements of MOSFETs. The extraction determines the intrinsic elements of the small-signal equivalent circuit. As a result, a new method to determine the gate capacitance is presented. This deembedding procedure is based on an analytical solution of the equations and facilitates the determination of the elements at any specific frequency. Moreover, a temperature noise model is presented, which is based on the small-signal equivalent circuit with an analytical description of the channel noise. This enables a complete noise modeling of all four noise parameters and the determination of the dominant noise sources. Finally, the noise-figure measurements are compared with the simulation results.
A BOTTLENECK-BASED GROUP SCHEDULING PROCEDURE FOR JOB-SHOP CELLS

ABSTRACT The similarity of process requirements in cellular manufacturing (CM) frequently causes a load imbalance in production planning and control stage. Thus, the bottleneck phenomenon is not atypical in a CM environment. This work proposes a two-stage exhaustive bottleneck-based group scheduling procedure (BGSP) to improve cells with load imbalance. To our knowledge, the impact of the bottleneck management on group scheduling in job-shop cells is examined here for the first time. The BGSP attempts to fully utilize the bottleneck machine to minimize makespan. A simulation model and the experimental environment are designed for examining the performance of the BGSP and effects of the experimental factors, i.e., setup-to-run time ratio, number of part families, bottleneck-to-nonbottleneck load ratio, and scheduling rules. Scheduling rules compared herein consist of two single-stage and five two-stage group scheduling rules discussed in previous studies. The BGSP shows the best average makespan as well as the most robustness. Results in this work demonstrate the practical nature of bottleneck management on group scheduling in cellular manufacturing systems.
The Analysis of OmpA and Rz/Rz1 of Lytic Bacteriophage from Surabaya, Indonesia

A good strategy to conquer the Escherichia coli-cause food-borne disease could be bacteriophages. Porins are a type of β-barrel proteins with diffuse channels and OmpA, which has a role in hydrophilic transport, is the most frequent porin in E. coli; it was also chosen as the potential receptor of the phage. And the Rz/Rz1 was engaged in the breakup of the host bacterial external membrane. This study aimed to analyze the amino acid of OmpA and Rz/Rz1 of lytic bacteriophage from Surabaya, Indonesia. This study employed a sample of 8 bacteriophages from the previous study. The OmpA analysis method was mass spectrometry. Rz/Rz1 was analyzed using PCR, DNA sequencing, Expasy Translation, and Expasy ProtParam. The result obtained 10% to 29% sequence coverage of OmpA, carrying the ligand-binding site. The Rz/Rz1 gene shares a high percentage of 97.04% to 98.89% identities with the Siphoviridae isolate ctTwQ4, partial genome, and Myoviridae isolate cthRA4, partial genome. The Mann–Whitney statistical tests indicate the significant differences between Alanine, Aspartate, Glycine, Proline, Serine (p=0.011), Asparagine, Cysteine (p=0.009), Isoleucine (p=0.043), Lysine (p=0.034), Methionine (p=0.001), Threonine (p=0.018), and Tryptophan (p=0.007) of OmpA and Rz/Rz1. The conclusion obtained from this study is the fact that OmpA acts as Phage 1, Phage 2, Phage 3, Phage 5, and Phage 6 receptors for its peptide composition comprising the ligand binding site, and Rz/Rz1 participates in host bacteria lysis.

The planar artificial transmission line is composed with both a dual transmission line and the Π-model technique. The occupied size of the proposed broadband hybrid coupler is merely 47% of the size of a conventional design. The compact size coupler demonstrates well-behaved wideband response and good agreement with measurement.
Myers-briggs Personality Prediction and Sentiment Analysis of Twitter using Machine Learning Classifiers and BERT

Twitter being one of the most sophisticated social networking platforms whose users base is growing exponentially, terabytes of data is being generated every day. Technology Giants invest billions of dollars in drawing insights from these tweets. The huge amount of data is still going underutilized. The main of this paper is to solve two tasks. Firstly, to build a sentiment analysis model using BERT (Bidirectional Encoder Representations from Transformers) which analyses the tweets and predicts the sentiments of the users. Secondly to build a personality prediction model using various machine learning classifiers under the umbrella of Myers-Briggs Personality Type Indicator. MBTI is one of the most widely used psychological instruments in the world. Using this we intend to predict the traits and qualities of people based on their posts and interactions in Twitter. The model succeeds to predict the personality traits and qualities on twitter users. We intend to use the analyzed results in various applications like market research, recruitment, psychological tests, consulting, etc, in future.
Serum Level of Complement C1q is Associated with Contrast-Associated Acute Kidney Injury in Patients Undergoing Emergency Percutaneous Coronary Intervention

Background As an inflammatory factor, complement C1q is related to the prevalence and progression of atherosclerosis; however, in patients undergoing emergency percutaneous coronary intervention (PCI), it is unclear whether C1q is related to the prevalence of contrast-associated acute kidney injury (CA-AKI). Methods From November 2018 to March 2021, 1182 patients who underwent emergency PCI were continuously recruited. Patients were divided into CA-AKI group (n = 234) and non-CA-AKI group (n = 948). CA-AKI was defined as an increase in serum creatinine from the baseline level (≥25% or ≥0.5 mg/dL) 48–72 hours after contrast exposure. All subjects were tested for serum C1q levels when they were admitted to the hospital. Results Among the 1182 patients undergoing emergency PCI, 234 patients (19.80%) developed CA-AKI. The level of preoperative serum complement C1q in the CA-AKI group was significantly higher than that in the non-CA-AKI group. Logistic regression and restricted cubic spline analyses showed that the incidence of CA-AKI was positively associated with the serum C1q level pre-PCI. Univariate and multivariate logistic regression analyses showed that C1q was an independent predictor of whether CA-AKI occurred after emergency PCI. The area under the curve (AUC) of the C1q was 0.703 [95% confidence interval (CI) 0.667–0.739] in patients receiving emergency PCI. CA-AKI model included the following three predictors: C1q, eGFR, and IABP use. The AUC of forecast probability was 0.718 [95% CI 0.682–0.754]. Conclusion In patients receiving emergency PCI procedure, a high C1q level before PCI is associated with the increased risk of CA-AKI.
Locating the Best Global R&D Centers for Laptop Computer Using a Fuzzy Integral Based Fuzzy MCDM Model

Research and development (R&D) is one of the most important core-competences of multinational enterprises (MNEs) in the globalization era. However, due to the high risks and high investments of international R&D, locating a global R&D center to an appropriate place is one of the most critical factors for international R&D project successes. Considering the characteristic of inter-dependences between criteria, a non-additive fuzzy integral based fuzzy multiple criteria decision making (FMCDM) model will be proposed for assisting decision makers to evaluate where the most appropriate locations are. An empirical study based on a real Taiwanese based laptop computer company will be used for demonstrating the feasibility of this proposed non-additive fuzzy integral based FMCDM frameworks. Based on the empirical study results, Silicon Valley is still the most suitable place for locating the laptop computer R&D center(s). The results demonstrated the feasibility of this model. Meanwhile, the empirical study results can be used for the laptop computer company’s locating of international R&D centers as well as expanding its innovation competences.
Effect of Nocturnal Oxygen on Blood Pressure Response to Altitude Exposure in COPD – Data from a Randomized Placebo-Controlled Cross-Over Trial

Purpose Patients with chronic obstructive pulmonary disease (COPD) are particularly vulnerable to hypoxia-induced autonomic dysregulation. Hypoxemia is marked during sleep. In COPD, altitude exposure is associated with an increase in blood pressure (BP) and a decrease in baroreflex-sensitivity (BRS). Whether nocturnal oxygen therapy (NOT) may mitigate these cardiovascular autonomic changes in COPD at altitude is unknown. Materials and Methods In a randomized placebo-controlled cross-over trial, 32 patients with moderate-to-severe COPD living <800 m were subsequently allocated to NOT and placebo during acute exposure to altitude. Measurements were done at low altitude at 490 m and during two stays at 2048 m on NOT (3 L/min) and placebo (3 L/min, ambient air) via nasal cannula. Allocation and intervention sequences were randomized. Outcomes of interest were BP, BRS (from beat-to-beat BP measurement), BP variability (BPV), and heart rate. Results About 23/32 patients finished the trial per protocol (mean (SD) age 66 (5) y, FEV1 62 (14) % predicted) and 9/32 experienced altitude-related illnesses (8 vs 1, p < 0.05 placebo vs NOT). NOT significantly mitigated the altitude-induced increase in systolic BP compared to placebo (Δ median −5.8 [95% CI −22.2 to −1.4] mmHg, p = 0.05) but not diastolic BP (−3.5 [95% CI −12.6 to 3.0] mmHg; p = 0.21) or BPV. BRS at altitude was significantly higher in NOT than in placebo (1.7 [95% CI 0.3 to 3.4] ms/mmHg, p = 0.02). Conclusion NOT may protect from hypoxia-induced autonomic dysregulation upon altitude exposure in COPD and thus protect from a relevant increase in BP and decrease in BRS. NOT may provide cardiovascular benefits in COPD during conditions of increased hypoxemia and may be considered in COPD travelling to altitude.
Computer-Aided Determination of Microwave Two-Port Noise Parameters

The least-squares fit of measured noise figures as a function of source admittance is an accurate and rapid method also convenient from the experimental point of view, to determine linear two-port noise parameters. However, to avoid the erroneous results often obtained by experimenters, this paper presents some criteria to be followed in choosing the proper source admittances. In order to apply the method to microwave two-ports, a relationship relating noise parameters in a linearized form is introduced. The analytical developments are in terms of effective input noise temperature of the two-port. Experimental. results for a microwave transistor are also reported as a function of experimental redundancy.
