According to the latest report on urban cancer in China published in 2017: China is one of the countries with the fastest growing incidence of breast cancer, and the age of onset has gradually become younger. Newly diagnosed breast cancer patients in China account for 12.2% of new breast cancer patients worldwide, and the mortality rate is 9.6%. A large amount of clinical experience has proven that the survival rate of breast cancer detected at an early stage is significantly higher than that detected at an advanced stage. Imaging examination is an important method for early detection of breast cancer. With the advent of the Artificial Intelligent, the method of AI + medical imaging has been widely used in lungs, breasts, heart, skull, liver, prostate, bones and other parts. Methods used in breast cancer screening include: breast self-examination and clinical physical examination, mammography of mammography of the breast, ultrasound of the breast, and magnetic resonance imaging (MRI) of the breast. The advantages and disadvantages have been reflected in the development and application in recent years. This article will review the advantages and disadvantages of combined diagnosis of AI and breast medicine. It is hoped that the artificial intelligence of medical imaging screening for breast diseases has a brighter and broader prospect.

Due to the need for high performance and reduced commercial cost of ownership, and due to many outstanding advantages such as high strength and light weight, steel has been widely used in engineering practice. In the case of fire, in order to prevent and protect these structures, it is the key issue to study the fire behavior environment. The engine room is also the source of power for ships. It is a high-risk area with frequent fires. Therefore, this paper mainly uses FDS to conduct numerical simulation research through a scaled-down engine room with a size of 3m×3m×3.5m. The change of temperature, pressure and smoke movement in the closed cabin with time at a fire source height of 1.5m is studied. The research shows that the fire behavior inside the closed cabin conforms to the two-zone model, and the fire suppression method of the closed fire has its significant advantages, And looked for the best time to reopen the cabin and the location of subsequent repair structures.

In order to solve the problems of low utilization rate of large parking lots and low efficiency of parking turnover, it is proposed to use A-star algorithm to plan the shortest path for finding a car, and run it in Android system to realize reverse car-searching. By analyzing the current situation of large underground parking lot barriers, A-star algorithm converts the starting point to the destination route into the corresponding parking space to the destination parking space path, calculates the optimal path and provides real-time path car navigation for the vehicle owner. According to the path searched by the A-star algorithm in the Android system, the time spent by the user to blindly search for the vehicle is largely saved, and the parking space utilization rate and the parking turnover rate are effectively improved. Therefore, the research has certain application value in the large parking lots.

Savanna biome is endowed with many tree species bearing edible fruits, seeds and nuts for human consumption. These fruits play an important role in human nutrition owing to their nutritional values, vitamins, minerals, anti-oxidants and low anti-nutritional factors. The nutritional and anti-nutritional composition of Adansonia digitata and Parkia biglobosa pulp and seeds from guinea savanna eco-system were examined in this study. The nutritional and anti-nutritional composition of the fruits differs. Moisture content was higher (11-18%) in the fruit pulp than in the seeds while the seeds of the two species are rich in protein (16-20%). Parkia biglobosa seeds proved a better source of crude fat (13%), crude fiber (10%), the ash content was slightly higher (4-5%) in the seeds than the fruit pulp. Crude fat (7.91%), crude fibre (7.52%) was higher in Adansonia digitata seed than the fruit pulp. Anti-nutritional content of Adansonia digitata and Parkia biglobosa was generally low, indicating that their consumption would not pose nutritional or health challenges. However the higher anti-nutritional factor in the seeds could be reduces through appropriate processing techniques.

The contamination of soil by lead has one of the major environmental problems globally. In present study, the experiment was carried out for lead contaminated soil with four plant species i.e., A. esculentus, A. sativa, G. abyssinica and G. max that were subjected to six lead concentrations i.e., 100, 200, 400, 600, 800 and 1000 mg Pb kg-1 soil. Soil without spiked were taken as control and investigated for lead phytotoxicity, tolerance and accumulation. After 12 weeks of experiment, lead toxicity on growth and biochemi-cal parameters were determined. For four plant species, seed germination and most of the growth parameters were significantly (p

Trivandrum central railway station is one of the biggest customers of Kerala water au-thority. The water consumption of railway station is about 50 ML/ month. A major por-tion of the water consumed is utilized for washing trains and tracks. Therefore, about 0.8 MLD of waste water is produced as train and track wash water in the Trivandrum cen-tral railway station. This waste water is discharged into public sewage line without any treatment. If this waste water can be reclaimed it can be reused for washing trains, tracks and platforms. In this study, the waste water samples at Trivandrum railway station were taken from three sources (Bio toilet effluent, fresh train wash water, sewage line waste water) and examined for the water quality parameters. The initial water quality parameters of the sample inferred that this waste water is treatable and reclaimable. For that a lab scale model of treatment unit was set up. After the treatment, the maximum BOD reduction was 94%, COD reduction 82.5%, Total solids reduction 98% and oil& grease reduction 99% was reported. The final effluent quality parameters satisfied KSPCB limits. The maximum quantity of waste water produced was found as 0.8 MLD from the data. By treating 8L of waste water in the lab scale model, a good quality effluent of 2.5L was obtained. By implementing a WWTP in the Trivandrum railway station 0.25 MLD of water can thus be reclaimed.

In this study, we investigated the effect of environmental conditions on the composition in fatty acid and the yield of argan oil of seeds from seven locations following an increase of aridity gradient; Essaouira, Tamanar, Imouzzer, Admine, Ait Baha, Merght and Bouizakarne. Indeed, the analysis of the composition of argan oil showed that the saturated fatty acids varied in the same way in the fruits of the studied plants. Therefore, oleic acid increased with altitude and linoleic acid decreased with aridity. Moreover, no significant differences were found on oil yield of the studied areas. Furthermore, we compared the antioxidant activity of alimentary and cosmetic oil. The results showed that alimentary oil had the highest antioxidant capacity compared to cosmetic oil.

Nanobiotechnology holds a great potential in various fields of life sciences. Nanotechnology involves the use of materials with components that have dimensions less than 100nm. The demand for biosynthesized nanoparticles increased day by day due to its ecofriendly and compatibility when compare to chemical method of synthesis. Application of nano-sized materials is an emerging area of nanotechnology. Molybdenum (Mo) nanoparticle was synthesized using fast, convenient, eco-friendly biological method from the aqueous extract of plumbago zeylanica. The same was synthesized using sol-gel method also. The nanoparticles synthesized by both the methods were characterized by Fourier transform infrared spectroscopy (FTIR), ultra violet spectroscopy (UV), scanning electron microscopy (SEM) and x-ray diffraction spectroscopy (XRD) studies. Molybdenum nanoparticles were found to be inhibiting the growth of bacteria and also act as effective catalyst.

Recently AISI 301LN grade austenitic stainless steel shows potential applications in manufacturing metro coach, oil tankers, bus body structures and wheels etc. Extensive strain induced martensite (SIM) formation property at crack tip of this steel helps toreduce frequent failure of this material. Formation of hard phase ‘SIM’ at crack tip delay crack propagation during fracture. In this way this type of steel promotes to make safe structural components. To fulfill European commission target before the year 2030, several attempts are going to enhance the mechanical performance of this particular steel by applyingadvanced thermomechanical treatments.In this regard only cold rolling and annealing treatments were used extensively in pastto make nano/ultra-fine grain structure, so that better structural properties can be achieved. It was found that, best mechanical properties (830 MPa Y.S., 953 MPa U.T.S., 36% elongation) were achieved after 80% cold rolling of this steel at ice-water mixture and annealing at 7000C for 20 minutes due to formation of ultra-fine grain (~0.74µm) structure. So in this review article all its thermomechanical properties are explored to find a scope towards further enhancement of its mechanical properties by advanced thermomechanicaltreatment to make safe body white structure of a vehicle.

Rupture of incisional hernia, with consequent emergency laparotomy and repair, is an uncommon complication of pregnancy. The risk to the mother and baby is enormous. We present an un-booked 29 year old G4P2+1 (1- alive) with one previous caesarean section at 29 weeks of gestation. She had a huge anterior abdominal wall incisional hernia with gravid uterus as content. She was admitted on conservative management on account of abdominal pain and preterm contractions, but subsequently developed spontaneous rupture from an ulcer with bowel evisceration. She had emergency laparotomy and repair but unfortunately had unavoidable bowels injury as they were morbidly adherent to the anterior abdominal wall with injury necessitating resection and re-anastomosis with caesarean section. The neonate suffered early neonatal death. The presence of ulceration may be a predictor of adverse maternal and foetal outcome
