Developing Potential in the Family Business - Learnings from a Queen Concert

Field: Business, Management and Accounting (Social Sciences)

Psychological Capital (Hope, Optimism, Resilience, Efficacy) is a powerful psychological resource to leverage the idiosyncratic potential of the family firm and to enhance performance through the attainment of goals. By developing Psychological Capital, the family firm can address critical issues which threaten sustainability, including reduced access to financial, human and social capital resources. The family firm is unique in terms of human capital due to the psychological attributes which are rooted in the duality of the organization, namely, family and business. As a result, the family business has a high dependency on the collaboration of both family and non-family members. This article demonstrates the benefit of developing Psychological Capital through lessons learned from a Queen concert.
EARLY POSTOPERATIVE OUTCOMES OF THE ESOPHAGECTOMY MINIMALLY INVASIVE IN ESOPHAGEAL CANCER

Field: Medicine (Health Sciences)

ABSTRACT BACKGROUND: The incidence of esophageal cancer is high in some regions and the surgical treatment requires reference centers, with high volume, to make surgery feasible. AIMS: To evaluate patients undergoing minimally invasive esophagectomy by thoracoscopy in prone position for the treatment of esophageal cancer and to recognize the experience acquired over time in our service after the introduction of this technique. METHODS: From January 2012 to August 2021, all patients who underwent the minimally invasive esophagectomy for esophageal cancer were retrospectively analyzed. In order to assess the factors associated with the predefined outcomes as fistula, pneumonia, and intrahospital death, we performed univariate and multivariate logistic regression analyses, accounting for age as an important factor. RESULTS: Sixty-six patients were studied, with mean age of 59.5 years. The main histological type was squamous cell carcinoma (81.8%). The incidence of postoperative pneumonia and fistula was 38% and 33.3%, respectively. Eight patients died during this period. The patient's age, T and N stages, the year the procedure was performed, and postoperative pneumonia development were factors that influenced postoperative death. There was a 24% reduction in the chance of mortality each year, associated with the learning curve of our service. CONCLUSIONS: The present study presented the importance of the team's experience and the concentration of the treatment of patients with esophageal cancer in reference centers, allowing to significantly improve the postoperative outcomes.
Novel Synthesis of α-Trifluoromethylated α-Amino Acid Derivatives from γ-Hydroxy-α-fluoro-α-trifluoromethyl Carboxamides

Field: Chemistry (Physical Sciences)

On treatment with an organoaluminum reagent such as trimethylaluminum or DIBAL-H, gamma-hydroxy-alpha-fluoro-alpha-trifluoromethyl carboxamides (1) give a single diastereomer of alpha-amino-alpha-trifluoromethyl-gamma-lactones (2), which are a ring-closed form of gamma-hydroxy-alpha-trifluoromethyl-alpha-amino acids. This intriguing reaction results from intramolecular replacement of the fluorine atom on the alpha-carbon atom with the nitrogen atom of the amide group, which occurs in an SN2 manner.

Medium-Range Quantitative Precipitation Forecasts from Canada’s New 33-km Deterministic Global Operational System

Field: Earth and Planetary Sciences (Physical Sciences)

Abstract The Meteorological Service of Canada (MSC) recently implemented a 33-km version of the Global Environmental Multiscale (GEM) model, with improved physics, for medium-range weather forecasts. Quantitative precipitation forecasts (QPFs) from this new system were compared with those from the previous global operational system (100-km grid size) and with those from MSC’s short-range (48 h) regional system (15-km grid size). The evaluation is based on performance measures that evaluate bias, accuracy, and the value of the QPFs. Results presented in this article consistently show, for these three aspects of the evaluation, that the new global forecast system (GLBNEW) agrees more closely with observations, relative to the performance of the previous global system (GLBOLD). The biases are noticeably smaller with GLBNEW compared with GLBOLD, which severely overpredicts (underpredicts) the frequencies and total amounts associated with weak (strong) precipitation intensities. The accuracy and value scores reveal gains of at least 12 h and even up to 72 h for medium-range QPFs (i.e., day 3 to day 5 predictions). The new global system even performs slightly better than MSC’s operational regional 15-km system for short-range QPFs. In a more absolute manner, results suggest that QPFs from the new global system may still have accuracy and value even at the medium range. This seems to be true at least for the smallest precipitation threshold, related to precipitation occurrence, for which the positive area under curves of relative economic value remains important, even for day 5 QPFs.
Study on springback of high tension steel following various temperature and local pre-heating in the roll forming process

Field: Engineering (Physical Sciences)

In this study, we studied spring-back phenomenon following pre-heating and various temperatures on forming sheet in roll forming process using finite element method (FEM) simulations. Material of forming sheet was high tension steel (POSTEN 60), and we analyzed spring-back phenomenon using material properties from room temperature to 500°C. For spring-back phenomenon analysis, FEM simulation results were thermal stress and strain according to temperature distribution on forming sheet. Assumed pre-heating methods were induction heating and laser heating, also this study assumed that pre-heating is same temperature conditions. Finally, the spring-back phenomenon was analyzed by induction preheating and laser pre-heating method.
Dynamic obstacle detection and avoidance for mobile robots

Field: Computer Science (Physical Sciences)

Obstacle avoidance is one of the key issues in robot motion planning. It is one of the critical issues especially because of the extensive use of unmanned vehicles in urban areas and for military purposes. During the course of its motion, a robot will have to deal with both static and dynamic obstacles. Some examples of static obstacles are buildings, trees, furniture etc. People, vehicles, other robots etc are the dynamic obstacles that the robot may encounter. For safe and unobstructed motion of the robots, timely detection and avoidance of these obstacles is extremely important. This thesis addresses this issue of obstacle avoidance for a mobile robot equipped with a laser range finder. In this thesis, a real time obstacle avoidance algorithm which can be used for robot navigation in unknown environments has been proposed. The algorithm can be used for avoiding both static and dynamic obstacles. The novelty of this approach lies in the idea of using a polar coordinate environment model for obstacle representation which is combined with a reactive approach to obstacle avoidance to form an efficient and innovative solution to the problem of obstacle avoidance. The range reading from onboard laser range finder is used to find the distance to the obstacle. A window is considered moving along with the robot as it moves. The area within the window is considered to be the region of interest and the obstacles within this area is considered for avoidance. Several experiments were conducted and the algorithm is found to work efficiently and expected results were obtained. The experiment is conducted using a Pioneer 3 robot with Hokuyo laser rangefinder mounted on it. A method to improve the algorithm for fast and non-uniform obstacle motion is also proposed.
Aspects of early West African trade

Field: Social Sciences (Social Sciences)

Abstract The evidence for early West African trade is reviewed. The development of trade is regarded as gradual from c. 1000 B.C. to c. A.D. 750. The early exploitation of gold resources was reflected in the affluence of the Senegambian and upper Niger regions with their large tumuli and megaliths. Reservations are expressed about the ninth‐century date proposed for Igbo Ukwu. A major expansion of trade occurred in the fourteenth century and was due to the exploitation of Ghanaian gold. Contacts between Mali and Ghana led to the development of a sophisticated brass technology and the use of Islamic weighting system amongst the Akan peoples. The results of excavations at the market town of Begho in Ghana, where the main settlement dates from A.D. 1350–1725, are reviewed. The evidence for local trade in pottery is discussed and the importance of intensive work on traditional potters is stressed.
Marginal cost of the calving interval in beef cows is not uniform

Field: Agricultural and Biological Sciences (Life Sciences)

To understand the profitability of reproduction management measures, an economic assessment based on a beef cow life simulation was proposed. It accounted for the discounted feeding costs of the dam and its calves for the different periods of their lives up to their sale and for the overall production from calves adjusted by mortality and culling. The calibration was proposed for various combinations of typical French and European situations. The maximal cash flow was observed for the lowest calving interval, corresponding to the maximal number of calves produced. The marginal cost of the calving interval was not uniform: on average, it was twice as high at a calving interval of 360 days (€1/day) as at 500 days (€0.5/day). It was also higher when age at first calving was lower and when culling was late or the replacement rate was low. The results were sensitive to the costs of the calves’ diets and to the market prices for calves. These assessments may assist the evaluation of the profitability of various measures taken in the field when faced with deteriorating calving intervals in beef production.
[Determination of steroid hormones in the amniotic fluid in prenatal genetic diagnosis].

Field: Medicine (Health Sciences)

In amniotic fluid from the second trimester of pregnancy levels of total and free testosterone, 17 alpha-hydroxyprogesterone and dehydroepiandrosterone were assessed. The median levels of total testosterone during the 15th to 24th week are 0.82 +/- 0.31 nmol/l in pregnancies with male foetuses and 0.32 +/- 0.11 nmol/l in pregnancies with female foetuses. The levels of free testosterone assessed by calculation from concentrations of SHBG and total testosterone are 0.15 +/- 0.04 for male and 0.05 +/- 0.04 nmol/l for female foetuses. The diagnostic reliability of sex determination of the foetus from the total testosterone concentration in amniotic fluid is 94% and estimation of free testosterone increases it further. The median normal 17 alpha-hydroxyprogesterone levels during the 15th to 23rd week of pregnancy are 8.7 +/- 3.5 nmol/l and do not depend on the sex of the foetus and week of pregnancy. The levels of dehydroepiandrosterone in amniotic fluid from the second trimester of pregnancy are in male foetuses 0.64 +/- 0.33 nmol/l and 0.61 +/- 0.32 nmol/l in female foetuses and do not differ. Assessment of testosterone levels serves as a supplementary method for determination of the sex of the foetus and may play an important part in the prenatal diagnosis of syndromes with agenesis of testicles. Estimation of 17 alpha-hydroxyprogesterone is used in prenatal diagnosis of congenital adrenal hyperplasia, estimation of dehydroepiandrosterone can be used in the prenatal diagnosis of hereditary forms of adrenal hypofunction.

Penerapan Internet of Things pada Greenhouse

Field: Engineering (Physical Sciences)

Climate change has many causes, one of which is an increase in atmospheric temperature or commonly called global warming. As a result of global warming, the climate around plants can become unfavorable to support the growth of crop production. One of the agricultural sectors affected by global warming is the greenhouse. These problems can be solved by implementing the internet of things and the nRF24L01 communication module in the greenhouse. This system will provide information in the form of temperature sensor readings, soil moisture sensors, soil pH and light intensity that can be seen without having to come to the greenhouse because this tool will send the monitoring results using the nRF24L01 communication module. Greenhouse owners or farmers can monitor the condition of their plants through the android-based blynk application, so they can maximize their harvests. An analysis was carried out regarding plants that use the internet of things and those that do not use the internet of things for several days. The results obtained from this analysis are plants that use the internet of things have better results and are cheaper in terms of costs.
Neuroendocrine tumors of the pancreas

Field: Medicine (Health Sciences)

Pancreatic endocrine tumors represent a heterogeneous group of lesions with behavior that ranges from indolent, benign tumors to aggressive malignancies. The majority of these lesions are nonfunctional and many are identified incidentally on axial imaging. Functional lesions can produce systemic symptoms due to secretion of a variety of hormones, including insulin, gastrin, glucagon and other pancreatic endocrine products. There is controversy over the staging and management of pancreatic endocrine tumors and much work is needed to better define the biology of this disease.
Printed in Great Britain CONDUCTION VELOCITIES AND THEIR TEMPERATURE COEFFICIENTS IN SENSORY NERVE FIBRES OF COCKROACH LEGS*

Field: Neuroscience (Life Sciences)

lends itself easily to measurements of conduction velocity in afferent nerve fibres from many of the larger mechanoreceptive sensilla of the leg. Conduction velocity is a quantity that can be measured quite precisely, and it has an important bearing on several open problems involving sensory mechanisms in insects, as well as in cellular neurophysiology more generally. One group of problems relates to the sensory transfer functions for tactile spine mechanoreceptors of Periplaneta, determined by Pringle &amp; Wilson (1952) and Chapman &amp; Smith (1963). Sensory transfer functions are quantita-tive expressions of the stimulus-response relationship, which describe some aspects of the temporal sensory code used in information transmission, and which provide useful insight in identifying component transducer mechanisms in the sensory ending. Conduction velocity is important in this context because it contributes quantitatively to the sensory code, and because it generates a quantifiable experimental artifact in the analysis of transducer mechanisms. In the present work these effects are evaluated and are shown to be small but not negligible. Secondly, conduction velocity provides a physiological estimate of nerve fibre
DFT Study on the Biosynthesis of Verrucosane Diterpenoids and Mangicol Sesterterpenoids: Involvement of Secondary-Carbocation-Free Reaction Cascades

Field: Chemistry (Physical Sciences)

[Image: see text] Some experimental observations indicate that a sequential formation of secondary (2°) carbocations might be involved in some biosynthetic pathways, including those of verrucosane-type diterpenoids and mangicol-type sesterterpenoids, but it remains controversial whether or not such 2° cations are viable intermediates. Here, we performed comprehensive density functional theory calculations of these biosynthetic pathways. The results do not support previously proposed pathways/mechanisms: in particular, we find that none of the putative 2° carbocation intermediates is involved in either of the biosynthetic pathways. In verrucosane biosynthesis, the proposed 2° carbocations (II and IV) in the early stage are bypassed by the formation of the adjacent 3° carbocations and by unusual skeletal rearrangement reactions, and in the later stage, the putative 2° carbocation intermediates (VI, VII, and VIII) are not present as the proposed forms but as nonclassical structures between homoallyl and cyclopropylcarbinyl cations. In the mangicol biosynthesis, one of the two proposed 2° carbocations (X) is bypassed by a C–C bond-breaking reaction to generate a 3° carbocation with a C=C bond, while the other (XI) is bypassed by a strong hyperconjugative interaction leading to a nonclassical carbocation. We propose new biosynthetic pathways/mechanisms for the verrucosane-type diterpenoids and mangicol-type sesterterpenoids. These pathways are in good agreement with the findings of previous biosynthetic studies, including isotope-labeling experiments and byproducts analysis, and moreover can account for the biosynthesis of related terpenes.
Protective effect of triflusal and acetylsalicylic acid against arachidonic acid induced cerebrovascular occlusion in anesthetized rats.

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Within 60 sec after intracarotid injection of 0.33 mg/kg arachidonic acid, a pronounced attenuation of electrocortical activity, approaching electrocerebral silence, was induced in the ipsilateral hemisphere of anesthetized and heparinized rats. This effect was a consequence of the cerebrovascular occlusion due to platelet aggregates induced by arachidonic acid. This model has been used to evaluate the protective effect of acetylsalicylic acid (ASA) and of triflusal 2 hr after a single oral dose of 50 mg/kg or after 50 mg/kg, for 5 days. Pentylenetetrazol at 10 mg/kg, i.v. exerts a stimulant effect on CNS, and was used as a positive control. ASA and triflusal exhibit a protective effect in about 35% of animals when acutely administered. After chronic treatments (5 days), the effect of triflusal (60% protection) was superior to that of ASA (27% protection) (p less than 0.01).
Design Of Fe7cr7-Xni4+Xtimo High Entropy Alloys With Modulated Fracture Toughness Through Adjustment Of Its Microstructure

Field: Materials Science (Physical Sciences)

Strengthened high entropy alloys (HEAs), represent a new paradigm for simultaneously achieving high strength and ductility, thereby circumventing this well-known trade-off in conventional and single-phase HEAs alloys. However, dynamic strengthening mechanisms and phase-boundary interactions during external loading remain unclear for these multiphase systems. The large fraction of phase boundary significantly impacts plastic flow in these systems. In this study, the microstructure, based on a mixture of ordered FCC/BCC ((L12, L21)/B2) phases and s phase, and small-scale mechanical behaviour has been evaluated for Fe7Cr7-xNi4+xTiMo (x=0, & 2) high entropy alloys obtained from of mechanically alloyed powders by spark plasma sintering (SPS). The use of nano and macro-indentation tests has allowed us to characterize the values of hardness and fracture toughness shown by the different (L12, L21)/(B2,s)ratios presented by high-entropy Fe-rich alloys.
Proposing a novel fuzzy control algorithm for automotive active stabilizer bars based on views of roll stability and ride comfort

Field: Engineering (Physical Sciences)

Using stabilizer bars in cars to limit rollover is a necessity applied to many vehicles today. In this article, the author proposes using a new fuzzy method to control the hydraulic stabilizer bars. Previous studies only focused on improving the roll stability of cars, while this article focuses on ensuring both the roll stability and ride comfort of the vehicle, which is considered the new contribution of the article. Vehicle oscillations are described through a complex nonlinear dynamic model. The MATLAB ® application performs the simulation with two specific cases, including fish-hook steering and J-turn steering. According to the findings of this research, the roll angle value is significantly reduced when using active stabilizer bars directed by the novel algorithm. In addition, the risk of the rollover was also strongly reduced for both simulations (there are four-speed thresholds used in each case). For the first case, rollover does not occur when the car utilizes active stabilizer bars, even when travelling at v 4 = 100 (km/h). In the other case, the rollover occurs only for the Active situation when travelling at a very high speed. In contrast, this phenomenon occurs in the None situation at v 1 and the Passive situation at v 2 . The results found from this work help to evaluate the performance of the fuzzy control algorithm for active stabilizer bars.
Crane design using product family approach

Field: Engineering (Physical Sciences)

The sector of construction is going through a phase of continuous improvement and finding a solution for complex problems. Starting from a basic material used for construction of building to the technology of advanced lifting systems for the efficient handling of building material, everywhere the improvement is evident. The crawler cranes are employed in construction sites relatively in less numbers when compared to tower cranes. But these cranes serve for greater purposes as they can move around the construction site to handle the loads at different locations. Thus crawler cranes can be used as a machine that can provide multi-location load lifting applications. This project aims to design and simulate different crawler crane models having a range of capabilities which is built through the computer software like Autodesk Inventor, Autodesk 3DS Max etc. The crane in general consists of enormous quantity of sub-parts and components that needs to be assembled in order to build an entire crane structure. For an Original Equipment Manufacturer (OEM), handling large number of distinctive parts for under each configuration of the crane is really a tedious job. So in order to simplify these difficulties the concept of Product Family approach is evolved. The Product family focuses on increasing the part commonality thus generating the modular components that fits across different families of cranes. The crawler crane models are designed by using product family approach having similarities of one or more components used across different variants of the cranes. Finally, the crawler crane models designed with product family approach is tested using the Graphics Processing Unit (GPU) based crane simulator software. Using this software, the crane models are simulated in the virtual industrial site. The lifting plan and position manipulation for the load is established. This lifting plan is generated with continuous monitoring on collision detection program that provides the safe trajectory to be followed during the material handling process.
