Irrigation with high salinity water influences plant growth, production of photosynthetic pigments and total phenols, leading to reduction in crop yield and quality. The objective of this study was to investigate the effects of potassium (k) foliar application in mitigating the negative effects of salt stress on pepper plants. A greenhouse experiment was conducted to investigate the effects of foliar application of potassium (k) on pepper plants grown with different salinity water irrigation (3000 and 6000 ppm as compared to tap water with salinity level of 300 ppm). Irrigation using high salinity water decreased plant height, biomass production, and fruit yield as compared to those of the plants irrigated by tap water. Photosynthetic pigments and total phenols increased in the former as compared to those of the latter plants. The most serious affect was for the plants under highest salinity irrigation (6000 ppm) as compared to that of the plants under moderate salinity irrigation (3000 ppm). Foliar application of potassium mono phosphate (kmP) at 200ppm concentration increased the plant growth, biomass production, and fruit yield. Chlorophyll_a content and total phenols increased significantly with foliar application of 100 ppm kmP. Further increase in foliar kmP concentration to 200 ppm had no significant benefits on photosynthetic pigments and total phenols content. This study demonstrated that foliar application of kmP, to some extent, mitigated the negative effects of high salinity water irrigation on pepper plant growth and fruit yield.

Benchmarking the ARPU and Productivity of Some Biggest Telecom Operators

引用

China Communications 2009年第1期6卷 104-108页

作者： Thorleif Herrstrm Gunnarsson & Herrstrm HB Sweden

This study is based on 15 of the biggest telecom operators globally. It focuses on two very simple measures, ARPU and Customers per Employee. The ARPU is a measure of the wealth of the specific context of the operation. While the Customers per Employee represents the productivity of the operator. Through a benchmark analysis, it shows that no one of the big operators has the ability to have both high ARPU and high productivity. The operators acting in high ARPU markets and with high ARPU market positioning seam to get "fat and lazy", while operators that have chosen markets with low GDP/capita and thus low expected ARPU are forced to be productive. The Chinese and Indian operators are characterized by "the big home market syndrome" with both low ARPU and low productivity. But the economy of scale fertilizes their profits. The African operators have very high productivities to accommodate themselves in very low-ARPU circumstances. Further, the research points out it is more possible for the operators in the "south-east" corner to enter the "north-west" corner through acquisition.

Perfect Single Qubit mirroring Effects on Two and Three maximally Entangled Qubits

Perfect quantum state mirroring in a chain of N spins is defined as the condition in which the state 丨i 丨of the chain is swapped into the state 丨N - i丨 within a time evolution interval r. Such a phenomenon is an interesting way of transfering entanglement. An expressions for the perfect mirroring of a single qubit contained in a spin chain were proposed in the past. We exploit such an expressions for calculating the evolution times in chains of both two and three spins. In the case of a chain of two qubits, we derive conditions under which the associated four Bell states diagonalize the Hamiltonian. It is found that for the two Bell states 丨Ф＋） and 丨Ф-）, perfect mirroring does not occur （i.e. entanglement is not preserved under swapping）. On the other hand, perfect single qubit mirror effect （entanglement preservation） indeed occurs for the other two Bell states 丨ψ＋） and 丨ψ-） which are mapped into 丨Ф＋） and 丨Ф-） respectively. For the case of a chain of three qubits, the effects of a perfect single qubit mirroring on a set of four maximally entangled three qubit states ψl, ψ2, X1, and X2are studied. Due to the fact that quantum mirroring preserves maximal entanglement, the states ψ1 and ψ2 are not altered. However, quantum mirroring changes the states X1 and X2 only if we apply perfect quantum state mirroring in the site a = 1 of the three qubits spin chain. The above constrains the preservation of maximal entanglement under qubit mirroring of such a state. Due to the fact that swapping has already been experimentally tested, a posible, experimental implementations of single qubit mirroring is possible.

Generalization of the linguistic aggregation operator and its application in decision making

Journal of Systems Engineering and Electronics 2011年第4期22卷 593-603页

A generalization of the linguistic aggregation functions （or operators） is presented by using generalized and quasiarithmetic means. Firstly, the linguistic weighted generalized mean （LWGm） and the linguistic generalized ordered weighted averaging （LGOWA） operator are introduced. These aggregation functions use linguistic information and generalized means in the weighted average （WA） and in the ordered weighted averaging （OWA） function. They are very useful for uncertain situations where the available information cannot be assessed with numerical values but it is possible to use linguistic assessments. These aggregation operators generalize a wide range of aggregation operators that use linguistic information such as the linguistic generalized mean （LGm）, the linguistic OWA （LOWA） operator and the linguistic or- dered weighted quadratic averaging （LOWQA） operator. We also introduce a further generalization by using quasi-arithmetic means instead of generalized means obtaining the quasi-LWA and the quasi-LOWA operator. Finally, we develop an application of the new approach where we analyze a decision making problem regarding the selection of strategies.

On the risks associated with wear quantification using profilometers equipped with skid tracers

引用

Friction 2016年第1期4卷 84-88页

作者： m.BELLANTONIO TRIBOtechnic 4 Rue Valiton Clichy 92110 France

In this study a wear track was generated on aluminium by rubbing it against a hard steel ball. The generated wear track has a typical depth of 50 μm and exhibits marked ridges on its borders. The cross section profiles were measured using two different stylus profilometers equipped either with skidless or skid probes and compared to a skidless reference instrument. It was found that the use of a skid probe can introduce significant distortion of the measured wear track profiles and thus errors in wear quantification. The reason for that is attributed to the presence of the ridges that, by elevating the skid, alter artificially the reference height used for profile measurement.

Night-time OH levels have been determined for Uk urban surface environments using two methods, the decay and steady state approximation methods. measurement data from the Uk National Environmental Technology Centre archive for four urban sites （Bristol, Harwell, London Eltham and Edinburgh） over the time period of 1996 to 2000 have been used in this study. Three reactive alkenes, namely isoprene, 1,3-butadiene and trans-2-pentene were chosen for the calculation of OH levels by the decay method. Hourly measurements of NO, NO〉 03, CO and 20 VOCs were used to determine night-time OH level using the steady state approximation method. Our results showed that the night-time OH levels were in the range of 1 × 10^3-1× 10^6 molecules/cm3 at these four urbap sites in the Uk. The application of a t-test of these analyses indicated that except Bristol, there was no significant difference between the OH levels found from the decay and steady state approximation methods. Night-time levels of the OH radical appeared to peak in summer and spring time tracking the night-time 03 levels which also passed through a maximum at this time.

Venopulmonary ECmO Improved Hypoxemia and Supported the Right Ventricle in a Patient with Decompensated Eisenmenger Syndrome

World Journal of Cardiovascular Surgery 2024年第1期14卷 7-19页

mechanical circulatory and/or respiratory assistance with extracorporeal membrane oxygenation (ECmO) has become a standard of care for patients with circulatory (venoarterial) and/or respiratory (venovenous) failure refractory to standard therapies. Adult patients with congenital heart disease are an increasingly recognized and growing population and include various groups, such as undiagnosed cases in childhood and palliated and/or corrected cases, which require subsequent care because of residual lesions, cardiac arrest/insufficiency, and arrhythmias, among other conditions. In addition, these patients are prone to developing pathologies that are typical of adulthood with a generally increased risk of morbidity and mortality because of their low reserves and organic damage associated with the underlying heart disease, which makes them candidates for ECmO. These patients represent an additional challenge in this therapy because malformations and the presence of a shunt can generally affect the usual cannulation methods and hemodynamic and oximetry monitoring. Thus, the configuration decision must be made on a case-by-case basis. Here, we present a cannulation method, venopulmonary artery ECmO, which provides hemodynamic and respiratory support, and may be ideal for patients with shunts and/or right ventricular dysfunction. To our knowledge, this is the first report of this configuration in patients with congenital heart diseases.
