In Vitro Culture of Rudimentary Embryos of Eleven Ilex Species1

The heart-shaped embryos, dissected from mature fruits of 11 Ilex (holly) species in 4 taxonomic sections, grown in modified White’s and Linsmaier and Skoog’s media jelled with Bacto-agar, produced seedlings. The rudimentary embryos were sufficiently autotrophic that a carbon source was the only organic compound needed in the media. There is a great variation in speed of in vitro development among individual embryos of the same species. The average embryo length of I. aquifolium L. increased linearly and most embryos reached germination size at the 55th day of incubation. The average embryo length of I. cornuta Lindl. increased sigmoidally and most embryos reached germination size at the 23rd day of incubation. The in vitro germination percentages for most species were above 80%. The survival rates after transplanting were higher than 75%. Sub-sequent seedling growth in greenhouses was healthy and vigorous.
How to negotiate with the Chinese?

The objective of this article is to enhance bargaining competences of managers negotiating with Chinese partners. It was achieved first by evaluating general characteristics of cross-cultural negotiations, followed by specifics of negotiating with the Chinese partners. Based on the mistakes managers do in negotiating with Chinese partners, special attention was directed to: prevailing values, communication specifics, dualism in negotiating with foreigners (ying-yang), the importance of keeping up one’s respect, relationships (guanxi) and differences in terms of time, organization of the meetings, and finally, their view on contracts. Mastering such specifics and avoiding too frequently rooted stereotypes are preconditions for success on the Chinese market
FEATURES OF SEEDS AND THEIR ULTRASTRUCTURE SURFACE VARIATIONS IN SOME TAXA OF GENUS Vicia (FABACEAE).

The morphological seed characters and seed testa structure variation of some taxa under 3 different sections of genus Vicia were studied. Scanning Electron Microscope (SEM) was used to clarify the seed testa variation patterns among the studied taxa. These taxa are; V.faba var. minor , V.faba var. equina , V.johannis var. procumbens , V.hyaeniscyamus , V.bithynica (section Faba ); V.sativa var. sativa (section Vicia ) and V.peregrina and V.mollis (section Peregrina ). Results of seed morphology and the structure of testa by SEM show that both varieties of V. faba are more close to each other than to any taxa of other studied sections, by sharing many characters, i.e. , seed colour and shape; papillae arrangement, size, density and apex shape; hilum groove colour, colour of center strip of hilum and most of hilum measurements. The three other taxa of section Faba ; V. johannis var. procumbens , V. hyaeniscyamus and V. bithynica , represent similarity in some studied seed characters, i.e. , seed shape; papillae arrangement, apex shape, size, density, number of papillae per unit and presence of wax and hour-glass cells on papillae apex. The results reveal also that both taxa of section Peregrina are similar to each other in many characters, i.e. , seed colour, shape and measurements; papillae arrangement, size, apex shape and absence of wax and hour-glass cells on papillae apex and colour of center strip of hilum, in addition to the other hilum measurements, i.e. length, width, shape and wavy edge of hilum groove. V. sativa var. sativa was medium in its character measurements, hence it is sharing the species of section Peregrina in some characters (seed colour, and shape; papillae arrangement, apex shape, size and absence of wax and hour-glass cells on papillae apex; hilum shape and colour of center strip of hilum) and the species of section Faba in other characters (papillae arrangement, density and absence of wax on papillae apex; hilum shape, colour and wideness of center strip of hilum).
Pathfinding in stochastic environments: learning vs planning

Among the main challenges associated with navigating a mobile robot in complex environments are partial observability and stochasticity. This work proposes a stochastic formulation of the pathfinding problem, assuming that obstacles of arbitrary shapes may appear and disappear at random moments of time. Moreover, we consider the case when the environment is only partially observable for an agent. We study and evaluate two orthogonal approaches to tackle the problem of reaching the goal under such conditions: planning and learning. Within planning, an agent constantly re-plans and updates the path based on the history of the observations using a search-based planner. Within learning, an agent asynchronously learns to optimize a policy function using recurrent neural networks (we propose an original efficient, scalable approach). We carry on an extensive empirical evaluation of both approaches that show that the learning-based approach scales better to the increasing number of the unpredictably appearing/disappearing obstacles. At the same time, the planning-based one is preferable when the environment is close-to-the-deterministic (i.e., external disturbances are rare).

Recent Updates in Vaccine Delivery through Microneedles

Recent coronavirus pandemic and its global socio-economic impact has re-emphasized the need for safe, fast, and efficient delivery of vaccines for humankind. With advent of technological advances, and to improve patient acquiescence, several techniques for fast, effective, and safe delivery of vaccines have been researched and published in the literature in last three decades. These delivery enhancement techniques include but are not limited to electroporation, microneedles (MN), ultrasound, iontophoresis, etc. This review aims at discussing the current research undergoing in vaccine delivery, specifically focusing on microneedles assisted, the historical background of microneedles and their introduction to drug delivery area, and a special focus on formulation challenges and stability in these systems. The review also sheds light on regulatory challenges one must keep in mind for bringing a successful microneedles-based vaccine delivery into market as well as a snapshot of current commercially available microneedles-based products in cosmetic and pharmaceutical industry.
The evolutionary development of the methodology of operational planning of construction production

The article describes a pilot implementation in the area of specialized work in the company "Stroy-West" system "Last planner". In the course of implementation, it was concluded that accurate planning can increase the productivity of construction activities, improve the efficiency of resource use. Usually, the significant part of the construction preparation process is reflected in business plans, which simplifies the design and content of the calculations. Meanwhile, this significantly deteriorates the quality of preparation process, and then the construction organization process, all the nuances of which must be determined by the project of organization of work, which establishes the process sequence and methods of organization of works on issue of the company's products. The need in material and technical resources can be assessed by two methods. The first method is the direct counting method which suggests evaluation of the material need based on the amount of work multiplied with corresponding consumption rate or by technology cards that indicating the requirement of vehicles, mechanisms, outfit, etc. by piece. Such method focuses on standards associated with the cost of the product. This method is most suitable for the purchase of simple items used in mass and impersonal way (fasteners, hardware, packaging material, etc.) by all divisions of the company. At the same time, operational control by itself is not decisive because is limited by information of organizational and managerial content. A comprehensive forecast of the costs of planning are the main preliminary factors for the successful construction management. "The last planner" can be consistently used, engineers-planners to make project schedules more predictable and to increase the likelihood that a workflow will flow evenly and projects are completed on time.
A Temperature Fiber Sensor Based on Tapered Fiber Bragg Grating Fabricated by Femtosecond Laser

A temperature fiber sensor based on tapered fiber Bragg grating (tapered FBG) fabricated by femtosecond laser has been proposed and realized with good reproducibility. Firstly, the fiber taper with 25 μm diameter and 1000 μm length is fabricated by arc-discharge elongation using two standard single-mode fibers. Secondly, two first-order FBGs are fabricated in tapered and non-tapered fiber regions for comparison. Both FBGs are point-by-point direct-written by femtosecond laser, and the grating lengths are 1000 μm. Thirdly, a temperature experiment is performed using a heating chamber, and experimental results show that in the range of 30~350 °C, the temperature sensitivity of the tapered FBG has increased from 11.0 pm/°C to 12.3 pm/°C. The tapered FBG proposed here can be further configured for sensing other parameters in physical, chemical, and biomedical applications.
The "Double-Edged Sword" Effect of High Job Performance on Work-Family Relationships: From the Perspective of the Work-Home Resource Model

Based on the work-home resource model perspective, a dual-path mediation model is constructed, and hypothesis testing is performed through data analysis. Studies have shown that high job performance can directly promote employees' self-efficacy through the resource gain pathway, thereby directly promoting their work-family gain, and can strengthen employees' self-depletion through the resource depletion pathway, thereby indirectly exacerbating their work-family conflict. The theoretical value of the research is that it opens up a new perspective for the research of high-performance employees in the organization and verifies the scientificity of the work-family resource model. In addition, it also provides practical inspiration for the management of high-performance employees in enterprises.
An Intelligent Cost-Efficient System to Prevent the Improper Posture Hazards in Offices Using Machine Learning Algorithms

In this research, an intelligent and cost-efficient system has been proposed to detect the improper sitting posture of a person working at a desk, mostly in offices, using machine learning classification techniques. The current era demands to avoid the harms of an improper posture as it, when prolonged, is very painful and can be fatal sometimes. This study also includes a comparison of two arrangements. Arrangement 01 includes six force-sensitive resistor (FSR) sensors alone, and it is less expensive. Arrangement 02 consists of two FSR sensors and one ultrasonic sensor embedded in the back seat of a chair. The K-nearest neighbor (KNN), Naive Bayes, logistic regression, and random forest algorithms are used to augment the gain and enhanced accuracy for posture detection. The improper postures recognized in this study are backward-leaning, forward-leaning, left-leaning, and right-leaning. The presented results validate the proposed system as the accuracy of 99.8% is achieved using a smaller number of sensors that make the proposed prototype cost-efficient with improved accuracy and lower execution time. The proposed model is of a dire need for employees working in offices or even at the residential level to make it convenient to work for hours without having severe effects of improper posture and prolonged sitting.
The vertical transmission of impulsive energy through the seated human

In the course of his normal activities man has to endure many physical and mental stresses. Evolution has endowed him with the ability to withstand such stresses provided that they do not exceed certain not very well-defined limits. However in his endeavours to investigate and experiment with his environment man often needs to exceed those limits and indeed may do so at times with potentially dangerous consequences. At other times he may find himself out of control of an otherwise safe situation, with similarly dangerous consequences. The present study was undertaken in order to investigate some of these physical limits. In particular the limits under investigation in this thesis are those of the man's tolerance to short duration high energy forces. [Continues. ]
Chinese Commodity Price Evidence Study for COVID-19 Shock and Price Stickiness Model Design

Based on the high-frequency price data, this article estimates the extent of price stickiness, identifies the pricing model, and applies the micro-results to analyze the dynamic characteristics of inflation. The results show that the price moves downward steadily during the COVID-19 epidemic. Secondly, the commodity price displays low stickiness, and the pricing model shows the time-dependent pricing (TDP) model in general. Finally, the inflation inertia is negative, indicating the macro-control is effective on COVID-19 epidemic and has the feature of contradiction to the economic cycle. And inflation inertia mainly comes from food commodities, which means that the anchoring object of the policy should be food commodities during the COVID-19 pandemic.
Recent Progress in the Determination of Polychlorodibenzo-p-Dioxins and Polychlorodibenzofurans by Mass Spectrometry: A Minireview

Abstract Mass spectrometry (MS) is the most reliable and accurate method for measuring polychlorodibenzo-p-dioxins (PCDDs) and polychlorodibenzofurans (PCDFs). High-resolution gas chromatography coupled with high-resolution mass spectrometry (referred to as magnetic double-focusing mass spectrometry) has been recommended as the ‘gold standard’ for the determination of PCDD/Fs in various samples. Many techniques and instruments, such as triple quadrupole MS (QqQ-MS), time-of-flight MS (TOF-MS), ion trap MS (IT-MS), Fourier-transform ion cyclotron resonance MS (FTICR-MS), and orbitrap MS, have been employed for the determination of PCDD/Fs. In this review, the progress in MS-related techniques used for PCDD/F determination in different matrices is updated. The sensitivity, recovery, and precision of these methods are summarized. The potential applications and unique merits of MS as a novel technique for the determination of PCDD/Fs are discussed.

The Effect of Supportive Organizational Climate on Employee Turnover Intention: A Cross-Level Analysis

Employee turnover affects the stable development of enterprise. It is not only an urgent problem that leaders need to think about, but also a research topic that management scholars and economists focus on. Turnover intention can well predict the turnover behavior of employee. Therefore, this paper investi-gates 50 enterprises and 305 employees in China and uses a cross-level regression model to test the mechanism between supportive organizational climate and employee turnover intention based on the organizational support theory. The results show that the supportive organizational climate can significantly reduce employee turnover intention, and job embedding plays a cross-level partial mediating role, and high commitment work system plays a cross-level moderating role between them. The research suggests that in the Chinese context, managers should not only devote themselves to creating a fine organizational climate for employee, but also actively implement high commitment work system to meet the spiritual needs and material needs of employee, thus reducing their turnover intention and promoting the long-term and stable development of the enterprise.
Applications de l'analyse harmonique réelle à l'étude des équations de Navier-Stokes et de Schrödinger non linéaire

Dans la premiere partie de la these on traite les problemes de l'existence, unicite et regularite des solutions faibles du systeme de navier-stokes tridimensionnel incompressible dans l'espace tout entier ; dans la deuxieme partie on considere l'existence de solutions autosimilaires pour une classe d'equations de schrodinger non lineaires. Les resultats fondamentaux du premier chapitre sont un theoreme d'equivalence des formulations differentielle et integrale du systeme de navier-stokes dans un cadre fonctionnel assez large et un resultat d'unicite des solutions milds (continues en temps) a valeurs dans les espaces fonctionnels critiques de lebesgue, de sobolev, de besov et de morrey-campanato. Dans le deuxieme chapitre on traite la question de l'existence des solutions milds sous une hypothese de regularite introduite par t. Kato qui suffit a garantir qu'il s'agit de solutions classiques en tout instant positif. On demontre ensuite un resultat de persistance de la regularite des solutions de koch et tataru dans l'espace des derivees de bmo issues d'une donnee initiale verifiant des proprietes supplementaires de derivabilite. Le temps d'existence de telles solutions ne depend que de la norme de koch et tataru. Dans le troisieme chapitre, il est encore question de persistance d'une propriete supplementaire verifiee par la donnee initiale, notamment de localisation et d'oscillation de son laplacien. La solution, unique dans l'espace de lebesgue critique, preserve alors cette propriete et ce pendant tout son temps de vie. Dans le quatrieme chapitre on etudie une classe d'equations de schrodinger non lineaires, avec non-linearite polynomiale d'ordre compris entre 1 et 2. A travers une analyse independante des termes lineaire et non lineaire, on demontre l'existence de solutions autosimilaires dans des espaces invariants modeles sur les espaces de sobolev avec une explosion en temps a l'instant initial. On etudie egalement le comportement asymptotique a l'infini des solutions appartenant a ce cadre fonctionnel.
Design and Analysis of Home Control Complex System Based on PLC Technology

The wide application of communication, automation, computer and other technologies not only provides a new direction for the development of home furnishing, but also makes the concept of “smart home” popular in recent years. The purpose of this study is to design a complex control system for smart healthcare home based on PLC technology. First, the research significance and background of this study are discussed, and the complex system, traditional PID control, and BP neural network algorithm are summarized. Second, the ZigBee wireless sensor network and PLC control system are studied, and the design of a smart health home control complex system based on PLC technology is analyzed. The experimental results show that when the indoor natural gas concentration is more than 1.25%, Y4 and Y3 are powered on, and Y2 is set as 1, that is, the alarm light is on, and the windows and exhaust fans are on. When the indoor flue gas (CO and CO2) concentration exceeds 0.06%, Y4 and Y3 are powered on, Y2 is set as 1, the alarm light is on, and the window exhaust fan is on. When the infrared detection output is 1, Y4 is powered on, Y2 is reset, the window is closed, and the alarm light is on. The human-machine interface of the Android mobile terminal of this system can be directly operated by the user and real-time monitoring data, reflecting the convenience of the design. Therefore, the design of complex home control system is of great significance in the home industry.
Review on Cancer and the Immune System

Cancer is a term for a large group of diseases caused by abnormal cells divide rapidly and spread to other tissue and organs. Under normal circumstances, so many cells multiply as long as the body is in need of them for the proper function daily. Healthy cells have a particular life cycle, reproducing and dying off in a way that is determined by the kind of cell. New cells replace old or damaged cells when they die. On the other hand, abnormal growth of cell or cancer disrupts this normal function. Cancer is one of the leading causes of death worldwide. It can migrate through the blood vessels or lymphatic system to different areas throughout the body. With regard to cancer diagnosis: one method is detection of a compromised immunological response of the patient toward his own tumor cells. And the second method is to use antisera, with which immunization of animals with human tumor extracts, for the detection of substances released into the blood by the tumor cells.
