Consumers appreciate leafy green vegetables such as baby leaves for their convenience and wholesomeness and for adding a variety of tastes and colors to their plate. In Western cuisine, leafy green vegetables are usually eaten fresh and raw, with no step in the long chain from seed to consumption where potentially harmful microorganisms could be completely eliminated, e.g., through heating. A concerning trend in recent years is disease outbreaks caused by various leafy vegetable crops and one of the most important foodborne pathogens in this context is Shiga toxin-producing Escherichia coli (STEC)...

To meet the demand of intelligent irrigation for accurate moisture sensing in the soil vertical profile, a soil profile moisture sensor was designed based on the principle of high-frequency capacitance. The sensor consists of five groups of sensing probes, a data processor, and some accessory components. Low-resistivity copper rings were used as components of the sensing probes. Composable simulation of the sensor’s sensing probes was carried out using a high-frequency structure simulator. According to the effective radiation range of electric field intensity, width and spacing of copper ring were set to 30 mm and 40 mm, respectively...

Chongqing mountain citrus orchard is one of the main origins of Chinese citrus. Its planting terrain is complex and soil parent material is diverse. Currently, the citrus fertilization, irrigation and other management processes still have great blindness. They usually use the same pattern and the same formula rather than considering the orchard terrain features, soil differences, species characteristics and the state of tree growth. With the help of the ZigBee technology, artificial intelligence and decision support technology, this paper has developed the research on the application technology of agricultural Internet of Things for real-time monitoring of citrus soil moisture and nutrients as well as the research on the integration of fertilization and irrigation decision support system...

BACKGROUND: Flexible ureteroscopic lithotripsy (URS) is rapidly becoming a first-line therapy for patients with renal and ureteral calculi. Most current medical infusion devices can only monitor infusion flow and pressure, but not renal pelvic pressure (RPP). PATIENTS AND METHODS: We designed a patented intelligent system to facilitate flexible URS that included an irrigation and suctioning platform and a ureteral access sheath (UAS) with a pressure-sensitive tip, enabling regulation of the infusion flow precisely and control of the vacuum suctioning by computerized real-time recording and monitoring of RPP...

With the development of the society and economy, as well as the rapid increase of population, more and more water is needed by human, which intensified the shortage of water resources. The scarcity of water resources and growing competition of water in different water use sectors reduce water availability for irrigation, so it is significant to plan and manage irrigation water resources scientifically and reasonably for improving water use efficiency (WUE) and ensuring food security. Many investigations indicate that WUE can be increased by optimization of water use...

Knowledge of crop abiotic and biotic stress is important for optimal irrigation management. While spectral reflectance and infrared thermometry provide a means to quantify crop stress remotely, these measurements can be cumbersome. Computer vision offers an inexpensive way to remotely detect crop stress independent of vegetation cover. This paper presents a technique using computer vision to detect disease stress in wheat. Digital images of differentially stressed wheat were segmented into soil and vegetation pixels using expectation maximization (EM)...

Emission tomography has provided a new insight in brain mechanisms past years. Although reconstructions are nowadays mostly static, trend is going toward dynamic acquisitions and reconstructions. This opens a new range of investigations, for instance for drugs discovery. Indeed new drugs are studied through the dynamic ability of tissues to catch them. However, it is required to know radiotracer concentration of blood that irrigates tissues in order to draw conclusions on potentials of these drugs. This concentration is called 'input function' and this paper presents a new method for measuring it in a non-invasive way...

The concept of an intelligent steerable surgical instrument system has been described by various authors. Since 1998, telesurgical minimally invasive procedures have been performed with the da Vinci system, mainly for cardiac bypass surgery. We present our initial experience using the device for robot-assisted laparoscopic radical prostatectomy. The intuitive surgical system consists of two main components: the surgeon's viewing and control console with 3D-imaging, and the surgical arm unit that positions and manoeuvres detachable surgical instruments...

At less than 1000 km3/year, the world's annual use of groundwater is 1.5% of renewable water resource but contributes a lion's share of water-induced human welfare. Global groundwater use however has increased manifold in the past 50 years; and the human race has never had to manage groundwater use on such a large scale. Sustaining the massive welfare gains groundwater development has created without ruining the resource is a key water challenge facing the world today. In exploring this challenge, we have focused a good deal on conditions of resource occurrence but less so on resource use...

Multipurpose operation is adopted by most reservoirs in Taiwan in order to maximize the benefits of power generation, water supply, irrigation and recreational purposes. A multiobjective approach can be used to obtain trade-off curves among these multipurpose targets. The weighting method, in which different weighting factors are used for different purposes, was used in this research work. In Taiwan, most major reservoirs are operated by rule curves. Genetic algorithms with characteristics of artificial intelligence were applied to obtain the optimal rule curves of the multireservoir system under multipurpose operation in Chou-Shui River Basin in central Taiwan...

The recent progress in endoscopic surgery, which is highlighted by the complexity of fundoplication, stomach surgery and colorectal surgery, has revealed major restrictions with difficult surgical manipulations. Mobilisation, dissection and suturing techniques are hampered mainly by the limited degrees of freedom of the conventional rigid instruments (translation along and rotation around the longitudinal axis and the limited play in the access channel). The frequent interchange of instruments such as coagulation forceps, scissors and suction-irrigation probe is time-consuming...

A study was conducted to determine the accuracy of tympanic thermometers for measuring the temperature of warmed fluids in fluid bags and in tubing at the delivery site (ie, beside the intravenous [IV] catheter). One-liter 0.9% saline bags were warmed in a microwave oven. A thermocouple electronic temperature probe was then used to measure the reference temperature. The probe was inserted into each bag and bathed in the fluid. Temperature changes were recorded simultaneously over a 20-minute period using the probe and a First Temp Tympanic Thermometer (Intelligent Medical Systems, Inc, Carlsbad, CA)...

Whilst endoscopic surgical procedures are getting increasingly more complex, in the various surgical disciplines mono- and bifunctional instruments are only slowly being replaced by multifunctional ones. Therefore a complex, intelligent system was developed, the central part of which is a multifunctional instrument. All basic functions necessary for surgical laparoscopy are integrated and comprise: cutting electrodes (unipolar and bipolar) which can be advanced or retracted pneumatically; coagulation forceps with mechanical control; and irrigation and suction devices...

Pigs are intelligent animals that can be formidable adversaries to humans because of their sharp tusks and their ability to attack swiftly. Domestic and feral pigs have an important role in the ecology of village life in Melanesia. A six-year review of all injuries that were caused by pigs that were referred from the villages in Milne Bay Province, Papua New Guinea, to the Provincial Hospital was completed. Some of the injuries that were seen among the 20 patients who were studied included: three penetrating abdominal injuries with prolapse and strangulation of the intestine; a "sucking" chest wound; bilateral pneumothoraces; two infected open fractures of the radius and the ulna; a perforating injury of the knee with septic arthritis; a hand injury with laceration of multiple tendons; an arterial injury of the wrist; injury of a tibial nerve with foot drop; and a severe scrotal injury with exposure of the testicles...

REVIEW
C J Cohen, S B Gusberg
Since Gusberg's description in 1947 of adenomatous hyperplasia (15), the role of precursors in the development of endometrial carcinoma has been well studied. There is now no doubt that in many patients histologic precursors can be demonstrated in the endometrial cavity prior to the development of invasive cancer. At this point in the continuum, interruption by hysterectomy or other therapy will insure the patient's health. We have discussed a wide variety of techniques designed to provide cytologic or histologic samples of the endometrium that are highly effective in the detection of early neoplasia...
