RESEARCH OF THE MAIN PROCESSING WORKS FOR ESTABLISHING A JERUSALEM ARTICHOKE CROP ON DIFFICULT AND CONTAMINATED SOILS

Jerusalem artichoke, is a technical plant that have some special features which make it suitable to be cultivated on degraded and difficult soils. However, processing difficult lands can cause major problems for farmers, in terms of using the right technology and reducing investment costs. The paper aim to address to the main challenges faced in preparing the soil for a Jerusalem artichoke culture, in order to maximize the productivity and efficiency

Central pancreatectomy - indications revisited

Institutul Clinic Fundeni, București, Al XI-lea Congres al Asociației Chirurgilor „Nicolae Anestiadi” din Republica Moldova și cea de-a XXXIII-a Reuniune a Chirurgilor din Moldova „Iacomi-Răzeșu” 27-30 septembrie 2011Pancreatectomia alternativă la rezecțiile standard (duodenopancreatectomia cefalica și pancreatectomia distală) pentru leziuni situate la nivelul istmului și corpului de pancreas. Principalul avantaj este reprezentat de conservarea atât a funcției exocrine cât și a celei endocrine a pancreasului. Dezavantajul major este reprezentat de morbiditatea postoperatorie crescută, reprezentată în principal de fistula pancreatică. Cele mai frecvente indicații ale pancreatectomiei centrale sunt reprezentate de tumorile benigne și cu potențial redus de malignizare. Chiar dacă acest procedeu chirurgical este contraindicat în carcinomul ductal de pancreas, totuși, o serie de alte malignități speciale ale pancreasului cum ar fi metastazele pancreatice ale altor neoplazii sau pancreatoblastomul pot beneficia, în anumite situații, de acest tip de intervenție chirurgicală. Deși nu este o procedură chirurgicală foarte frecvent utilizată, pancreatectomia centrală, își găsește locul în arsenalul rezectiilor pancreatice.Central pancreatectomy has emerged as a pancreas-sparing alternative technique to standard pancreatic resections (i.e. pancreatico-duodenectomy and distal pancreatectomy) for pancreatic lesions located to the isthmus and body. The main advantage is related to a better preservation of both exocrine and endocrine pancreatic functions. Conversely, the major concern is related to the high postoperative morbidity, mainly related to the postoperative pancreatic fistula rate. The most frequent reported indications for central pancreatectomy are represented by benign and low-malignant lesions of the pancreas. Although central pancreatectomy is not indicated for ductal adenocarcinoma of the pancreas, however, for certain special malignancies of the pancreas (i.e. metastasis to the pancreas of others neoplasia, pancreatoblastoma), central pancreatectomy has been proven to be a safe operation. Although central pancreatectomy is not a frequent operation, it should be included in pancreatic surgeons’ armamentarium for certain indications

SILVER GREEN SYNTHESIS ON BACTERIAL CELLULOSE MEMBRANES USING TANNIC ACID

Silver nanoparticles were deposed on bacterial cellulose (BC) membranes using tannic acid as reducing agent. The synthesis of silver nanoparticles was confirmed by scanning electron microscopy (SEM), energy dispersive spectroscopy with X-ray (EDX) and UV-VIS spectroscopy. The antimicrobial activity of BC-silver films was tested against E. coli K12-MG1655, all the composites having a good antimicrobial activity. These composites could be used for antimicrobial wound dressings

Esophageal resection- experience in center of general surgery and liver transplantation “Dan Setlacec” 2001-2011

CONSIDERATIONS ON ENERGETIC CROPS POTENTIAL

In order to breathe fresh and clean air, nature and terrestrial atmosphere should be preserved and protected. Carbon emissions represent one of the main enemies of air quality. Recently, carbon emissions have surpassed all the predictions because the excessive industrialization, becoming the determining factor for global warming. A viable alternative to carbon emissions reduction is the utilization of energy sources that can diminish the noxious substances emissions up to zero. This can be done by using the power of wind, sun, water, energy plants, etc. Among the energetic potential plants, the biomass is obtained- a form of renewable energy which final product is biofuel

USE OF DETACHING EQUIPMENT IN GRAPE POMACE PROCESSING TECHNOLOGY

The equipment is intended to operate within the fruit processing technological flows, respectively to detach- disintegrate the grape pomace which are formed during the fruit pressing using milling drums. These pomaces, usually are made up of fruit solid agglomerations, that have a greater seed concentration and humidity, especially when the rotary rollers are working with a certain distance between, in order to not crush the grape seeds. Based on these considerations, in the paper it is analyzed and presented the case in which the detacher can successfully be used in grape seeds separating technology from the pomace and its performances to separate the sub-products resulting from the grapes pressing operation

EQUIPMENT FOR EXTRACTING AND PLANTING EARTH BALE ROOT PLANTS

Trees are one of the biggest  organisms living on the planet and their role is extremely important, namely that to maintain the purity of air we breathe, improve water quality, prevent soil erosion, reduce noise level, ensure food, construction materials and eventually people comfort. Plantation and transplantation of trees by means of specialized equipment  in comparison with human force leads to an increased planting speed and higher yield, economically speaking. This paper is designed to present different constructive variants, at world level, of equipment for extracting and planting trees with earth bale at their roots, necessary for afforestation, landscape design, tree nurseries

A Garlic Derivative, S-allylcysteine (SAC), Suppresses Proliferation and Metastasis of Hepatocellular Carcinoma

Background: Hepatocellular carcinoma (HCC) is highly malignant and metastatic. Currently, there is no effective chemotherapy for patients with advanced HCC leading to an urgent need to seek for novel therapeutic options. We aimed to investigate the effect of a garlic derivative, S-allylcysteine (SAC), on the proliferation and metastasis of HCC. Methodology/Principal Findings: A series of in vitro experiments including MTT, colony-forming, wound-healing, invasion, apoptosis and cell cycle assays were performed to examine the anti-proliferative and anti-metastatic effects of SAC on a metastatic HCC cell line MHCC97L. The therapeutic values of SAC single and combined with cisplatin treatments were examined in an in vivo orthotopic xenograft liver tumor model. The result showed that the proliferation rate and colony-forming abilities of MHCC97L cells were suppressed by SAC together with significant suppression of the expressions of proliferation markers, Ki-67 and proliferating cell nuclear antigen (PCNA). Moreover, SAC hindered the migration and invasion of MHCC97L cells corresponding with up-regulation of E-cadherin and down-regulation of VEGF. Furthermore, SAC significantly induced apoptosis and necrosis of MHCC97L cells through suppressing Bcl-xL and Bcl-2 as well as activating caspase-3 and caspase-9. In addition, SAC could significantly induce the S phase arrest of MHCC97L cells together with down-regulation of cdc25c, cdc2 and cyclin B1. In vivo xenograft liver tumor model demonstrated that SAC single or combined with cisplatin treatment inhibited the progression and metastasis of HCC tumor. Conclusions/Significance: Our data demonstrate the anti-proliferative and anti-metastatic effects of SAC on HCC cells and suggest that SAC may be a potential therapeutic agent for the treatment of HCC patients. © 2012 Ng et al.published_or_final_versio

A model for quick load analysis for monopile-type offshore wind turbine substructures

A model for quick load analysis, QuLA, of an offshore wind turbine substructure is presented. The aerodynamic rotor loads and damping are pre-computed for a land-based configuration. The dynamic structural response is represented by the first global fore-aft mode only and is computed in the frequency domain with phases using the equation of motion. The model is compared to the state-of-the-art aeroelastic code Flex5. Both lifetime fatigue and extreme loads are considered in the comparison. In general there is good agreement between the two models. Some deviations for the sectional forces are explained in terms of the model simplifications. The differences in the sectional moments are found to be within 10 % for the fatigue load case and 10 % for the extreme load condition
