Achieving the food security strategy by quantifying food loss and waste. A case study of the chinese economy

Undernourished and food insecurity are recognized as two highly relevant topics. Approx-imately 820 million people in the world are undernourished and 2 billion people have moderate or severe food insecurity (FAO). In addition, globally roughly one-third of food is not consumed and is wasted. This article aims to provide an updated estimate of food loss and waste (FLW) in China as, in the period 2016–2018, there were still 122 million people in this country experiencing undernourishment. In this research, we use a top-down mass balance approach, discuss how it affects the achievement of SDG 2, Zero Hunger, that it is linked also to target 12.3 that “seeks to halve global food waste at retail and consumer levels, as well as to reduce food loss during production and supply” (United Nations). We point out some challenges that private and public policies still need to overcome to reduce FLW. The results of this research may contribute a more accurate baseline for the design of public policies and strategies related to FLW and the corresponding SDG

E. coli

Escherichia coli meningitis is a frequent pathology in children younger than 3 years old, but is an uncommon disease in adults. E. coli infection is the main cause of intrahospital bacteremia as a consequence of the employment of different medical procedures. Our patient, male, 69 years old, presented with fever, progressive difficulty in breathing, and shivers 24 h after transrectal prostate biopsy, with an absence of any other symptoms. He received prophylactic treatment with ciprofloxacin and later empirical treatment with ampicillin and tobramicin. After that, the patient presented with fever, headache, behavioral changes, somnolence, disorientation, a fluctuating level of conscience, cutaneous widespread pallor, and acute urinary retention. On physical exploration, we observed generalized hypoventilation, Glasgow 10, stiffness of the neck, inconclusive Kernig; the remaining neurological exploration was normal. Systematic of blood: leukocytes = 8,510/mm3 (94.5% polymorphonuclear), platelet = 87,000/mm3, pH = 7.51, pCO2 = 28.8 mmHg, pO2 = 61 mmHg, O2 saturation = 93.8%, and remaining values were normal. Chest X- ray, cranial CT scan, urine cultures were normal. Blood culture: E. coli. CSF: glucose <0.4 g/l, total proteins = 3.05 g/l, PMN = 7 cells. Microscopic examination of the CSF: Gram-negative bacilli; CSF's culture: abundant E. coli. The case of acute meningitis by multiresistant E. coli after transrectal prostate biopsy presented demonstrates that antibiotic prevention with ciprofloxacin is not absolutely risk free. Besides the use of antibiotic prevention for multiresistant microorganisms, the urologist and other physicians involved in the procedure must not forget that the rate of major complications of transrectal prostate biopsy is 1%, especially when it is performed in patients who will not benefit from that biopsy

Plasma and surface diagnostics of silicon nitride thin film coatings generated by SiH4+NH3 RF discharges.

Although plasma processing in low pressure electric discharge reactors has become an extensive and critical step in the fabrication of microelectronic devices, its development has been carried out mostly empirically so far, by changing external reactor parameters in order to develop the best achievable film properties, whereas the intrinsic state of the plasma has been largely unknown [1, 2]. In this work, silicon nitride (SiN) thin films have been grown on silicon samples and on AlGaN/GaN High Electron Mobility Transistors (HEMT) by Plasma Enhanced Chemical Vapor Deposition (PE-CVD). The SiN coatings have been produced in a RF discharge reactor, employing SiH4 and NH3 as precursors, at different electric powers and gas flow ratios. During depositions, the plasmas have been characterized by mass and time resolved quadrupole mass spectrometry, and the depletion ratios of parent gases have been observed. Afterwards, the refractive indexes and growth rates of the films have been analysed by ellipsometry, and their composition, by Fourier Transform Infrared Spectroscopy. The electrical characteristics and frequency responses of these films when deposited on HEMT (where they are just usually employed to passivate these devices against current collapses) have been studied too by means of DC, pulsed currents, and small signal RF measurements. The plasma characteristics for the different deposition conditions have been correlated with the subsequent changes in the properties of the films. A comparison with the results previously reported in the literature is addressed

Sorting on periodic surfaces

Particles moving on crystalline surfaces and driven by external forces or flow fields can acquire velocities along directions that deviate from that of the external force. This effect depends upon the characteristics of the particles, most notably particle size or particle index of refraction, and can therefore be (and has been) used to sort different particles. We introduce a simple model for particles subject to thermal fluctuations and moving in appropriate potential landscapes. Numerical results are compared to recent experiments on landscapes produced with holographic optical tweezers and microfabricated technology. Our approach clarifies the relevance of different parameters, the direction and magnitude of the external force, particle size, and temperature

La enfermedad crónica infantil. Repercusiones emocionales en el paciente y en la familia.

La OMS define la salud como el estado de completo bienestar físico, mental y social. De este modo, se pasa de entender la salud únicamente como un concepto biológico, para entenderla como una dimensión biopsicosocial (Rubio et al., 2010). En general, la enfermedad, sobre todo cuando es crónica, altera en gran medida tanto la vida del paciente, como la de todas las personas de su entorno, y hace necesaria una adaptación a la situación de todas las partes implicadas (particularmente el niño y la familia). En el siguiente trabajo se pretenden analizar las distintas estrategias de afrontamiento emocional que, según la bibliografía relevante en este tema, tanto el paciente pediátrico como su círculo social más importante adoptan ante la nueva situación.Investigación realizada gracias al Proyecto I+D con ref.: EDU2009-11950 del Ministerio de Ciencia e Innovación.peerReviewe

Hydronium Detection in Hardened Concrete

[EN] The monitoring of reinforced concrete structures allows us to detect the presence of aggressive agents into of the concrete matrix, on site and in a real time. These aggressive agents can produce the unexpected failure of the structures, thus discovering their presence is a fundamental aspect in the preservation of people safety and the durability of the structure. On the other hand, helps to reduce the cost of maintenance and repair operations, due to allow us to identify the problems faster, minimizing the intervention to be done. The present research paper was focused in the hydronium detection; the reduction of this species generates hydrogen, the hydrogen produces the embrittlement and cracking of the steel, which seriously compromises the right behaviour of the structure. The problem of hydrogen appears in industries such as ammonia processing or petrochemistry industries and nuclear power plants. All of them are industries in which a failure seriously compromises the welfare of people and the environment. Therefore, the detection of hydrogen penetration in reinforcement concrete structures in these cases are very interesting. In this study, with the purpose to detect the hydronium or hydrogen in the hardened concrete matrices is proposed the use of voltammetric sensor, which is part of a multisensory system called Electronic-Tongue. This is a preliminary study. The objective of these initial steps was to evaluate the detection capability of the sensor. Currently, have been designing a sequential test in order to evaluate the sensor in different partial hydrogen pressures with the purpose to develop mathematical models to the hydronium or hydrogen detection and quantification in hardened concrete matrix.The authors would like to express their gratitude to the Spanish Ministry of Science and Innovation for the pre-doctoral scholarship granted to Ana Martínez Ibernón (FPU 16/00723).

Wine lees are water-waste residues generated during maceration and fermentation steps of the vinification process and they constitute a source of high value compounds, such as polyphenols, mainly anthocyanins (AC). The exploitation of these dregs could contribute to the development of new wine-related products and could also lead to a sustainable growth of the wine industry due to the concentration of AC is 10 times higher in wine lees than in grape skins [1]. After the recovery of the polyphenols from wine lees, a wet solid waste remains with poor chemical potential. This residue can be recycled by a hydrolysis step. Supercritical water (SCW) has proved to be a suitable environment-friendly media for biomass hydrolysis due to its unique properties, such as a high diffusivities or low dielectric constant [2]. This hydrolysis produces a liquid product rich in sugars that can be used as feed in a fermentation step afterwards. However, the yield of this last step would be lower with wine lees than with conventional biomasses since its cellulosic fraction only constitutes 18%. The main objective of the hydrolysis of the wine lees residue is to obtain reduced sugars which are essential chemical building blocks in the so-called biorefinery cycle. A continuous pilot plant was used to carry out the hydrolysis of wine lees in SCW. This facility was based on a continuous reactor with instantaneous heating and cooling that allowed precise control of the reaction time and therefore, high recovery of sugars was achieved and avoiding sugar degradation reactions. A wine lees-water suspension (10% w/w) was continuously fed to the reactor using a pump at a flow rate of 1 kg/h and processed under 380-395ºC and 25MPa at different reaction times, between 0.056 and 0.076s. A brown liquid was obtained after the hydrolysis step, rich in hexoses (yield of 50%) such as cellobiose, glucose and fructose. It was also observed that increasing the reaction time and temperature favored the degradation of the recovered sugars into pyruvaldehyde and glycolaldehyde.Marie Curie Industry-Academia Partnerships and Pathways actions (FP7-PEOPLE-2013-IAPP-612208)Junta de Castilla y Leon and FEDER 2014-2020, proyecto VA040U16Ministerio de Economía y Competitividad Spain (CTQ2015-64892-R
