Virtual simulation of production line for ergonomics evaluation

To avoid ergonomic problems in the early planning stages of a production line and achieve more satisfactory planning and design, ergonomic simulation is particularly important in digital production line planning. An ergonomics analysis method is presented by using two theories： Ovako working posture analysis system （OWAS） and Burandt-Schultetus hand-arm force analysis （BSHA）. The processes of ergonomics analysis and simulation are discussed based on a platform of process simulation and process designer. As an example, the paper shows how ergonomics problems are considered in production line planning to make a better choice between different production line planning schemes.     

A new class of negative refractive index transmission line

We propose a new class of negative refractive index transmission line in which ideal operational amplifiers are applied to form the periodically loaded negative-impedance-converted inductors and capacitors. The phase response of the new trans-mission line is opposite to that of a positive refractive index conventional transmission line. Unlike the existing negative refractive index transmission line,the new negative refractive index transmission line is non-dispersive and thus can lead to many novel applications such as designing new broadband devices.     

Study on the expression and mutation of human telomeric repeat binding factor （hTRF1） in 10 malignant hematopoietic cell lines

Objective: Detecting the expression and mutation of human telomeric repeat binding factor (hTRF1) in 10 malignant hematopoietic cell line cells on the base of determining its genomic structure and its four pseudogenes to clarify if h TRF1 mutation is one of the factors of the activation oftelomerase. Methods: hTRF1cDNA sequences were obtained from GenBank, its genome structure and pseudogenes were forecasted by BLAST and other biology information programs and then testified by sequencing.Real-time RT-PCR was used to detect the expression ofhTRF1mRNA in 10 cell line cells, including myelogenous leukemia cell lines K562, HL-60, U-937, NB4, THP-1, HEL and Dami; lymphoblastic leukemia cell lines 6T-CEM, Jurkat and Raji. Telomerase activities of cells were detected by using telomeric repeat amplification (TRAP)-ELISA protocol. PCR and sequencing were used to detect mutation of each exon of h TRF1 in 10 cell line cells. Results: h TRF1 gene, mapped to 8q 13, was divided into 10 exons and spans 38.6 kb. Four processed pseudogenes of hTRF1 located on chromosome 13, 18, 21 and X respectively, was named as ψhTRF1-13, ψhTRF1-18, ψhTRF1-21 and ψhTRF1-X respectively. All cell line cells showed positive telomerase activity. The expression of hTRF1 was significantly lower in malignant hematopoietic cell lines cells (0.0338, 0.0108～0.0749) than in normal mononuclear cells (0.0493, 0.0369～0.128) (P=0.004). But no significant mutation was found in all exons of hTRF1 in 10 cell line cells. Four variants were found in part of intron 1,2 and 8 ofhTRF1. Their infection on gene function is unknown and needs further studies. Conclusion: hTRF1 mutation is probably not one of the main factors for telomerase activation in malignant hematopoietic disease.     

Planting Trees

Shouhl students make friends on line？ Some people say yes. Internet helps people make many friends. Chatting on line, students can express more freely, and even get help for their foreign lan- guage studies. Others, however, someone thinks students should not. They say making friends on line is a waste of time. It＇s not good for study. Besides. Even some students get cheated on line. It is my opinion that students should place their study, health and safety before other things. As for friendship, we can find it in our classmates and other people around us.

Characteristics of transgenic tomatoes antisensed for the ethylene receptor genes LeERT1 and LeERT2

Two stable transformed lines containing antisense LeERT1 or LeERT2 sequences and their hybridized line were investigated to determine the effect of LeERT1 and LeERT2 specificity in the ethylene receptor family in tomato （Lycopersicon esculenturn Mill.） on ethylene signaling. The transgenic line alel containing antisense LeER T1 displayed shorter length of seedling grown in the dark and adult plant in the light, severe epinastic petiole, and accelerated abscission of petiole explant and senescence of flower explant, compared with its wild type B 1. The transgenic line ale2 containing antisense LeERT2 also exhibited shorter hypocotyls and slightly accelerated abscission. The phenotypes of cross line dale of LeERT1 and LeERT2 were close to alel in many aspects. These results suggested that LeERT1 probably plays a relatively important role in ethylene signaling of tomato growth and development.

一体化电子式电流电压互感器研究

A high-performance current and voltage measurement system has been developed in power system.The system is composed of two parts:one current measurement element and one voltage measurement element.A Rogowski coil and a capacitive voltage divider are used respectively for the line current and voltage measurements.Active electronic components are used to modulate signal,and power supply for these components is drawn from power line via an auxiliary current transformer,Measurement signal is transmitted y optical fibers,which is resistant to electromagnetic induction and noise,With careful design and the use of digital signal processing technology,the whole system can meet 0.5% accuracy for metering and provides large dynamic range coupled with good accuracy for protective relaying use.     

Weld Characteristics and NC Bending Formability of QSTE340 Welded Tube

The mechanical characteristics of the weld joint were investigated by tensile test, microstructure test, and microhardness test. The welded tube NC bending tests were carried out to evaluate the weld on the formability of the QSTE340 welded tube. The results show that the wall thinning degree, cross-sectional deformation and springback angle increase significantly as the weld line is located on the outside of the bend compared with that located on the middle and inside, and the welded tubes produce nearly identical performance as the weld line is located on the middle and inside. The wall thickening degree decreases much as the weld line is located on the inside of the bend. So the welded tube can acquire good bending formability as the weld line is located in the region away from the outside of the bend.

Jokes and Humour

The Crowded Store It was the day of the big sale. Rumors of the sale(and some advertising in the local paper) were the main reason for the long line that formed in front of the store by 8:30,the store's opening time. A small man pushed his way to the front of the line,only to be pushed back,amid loud and colorful curse.On the man's second attempt,he was punched square in the jaw,and then thrown at the end of the line again. As he got up,he said to the person at the end of the line,“That does it! If they hit me one more time,I won't open the store!”一天,一个商店降价大甩卖。人们在8:30开店之前就排在了商店门前,排成了很长的一队。一个身材矮小的人想挤到队伍的前面,但在咒骂声中被推了回来。那个人又一次努力往前挤,这次下巴上重重地挨了几拳,然后被扔到了队伍最后。当他站

Analysis of Capacitive Parasitism in PWM Inverter—Fed Motor

The effects of parasitic capacitance in induction motor system are unnoticed when it is fed from the AC line,but they are obvious when supplied directly from a PWM inverter,Consequently,many parasitic problems occur.Such as motor-to-earth leakage current.Bearing current.incoming line current distortion and uneven distribution of electrical stresses along the winding.On the basis of the uniform transmission line principle.a complete equivalent circuit of the PWM inverter-fed motor system is presented,based on which all the capacitive parasitic problems mentioned obove are analyzed and simulated by means of PSPICE.All the results are consistent with the existing ones.
