The rapid development of economy and society has led to the rapid increase of the output of logistics outer packaging garbage. How to realize the classification and recycling of logistics packaging garbage by intelligent methods has become a key factor for human beings to achieve sustainable development. To solve this problem, this paper proposes an image recognition model of logistics packaging, which is a convolution neural network model based on multi-scale, and adds channel and spatial attention mechanism. The model uses multi-scale convolution to extract richer image features. The attention mechanism is used to adaptively adjust the parts that need to be focused on, and the feature extraction ability of the model is enhanced. Compared with the traditional manual sorting method, this paper uses the deep learning technology to intelligently and automatically classify the logistics outer packaging. The experimental results show that the classification accuracy of data sets can reach 96% by using the method of deep learning, which is very helpful to improve the classification efficiency of logistics outer packaging.

In a calving area on western Hardangervidda, Norway, shed antlers of female reindeer, Rangifer tarandus tarandus L., have been collected for several years. Many of these antlers have been chewed on by reindeer. In the literature antler chewing has been reported to take place on both shed and unshed antlers. Our observations support these findings. Based on the present observations it is suggested that the antlers may subserve the mineral householding of the animals under special conditions. The female reindeer has to pass through a nutritionally marginal season which often coincides with calving. Bringing the bony antlers to the calving areas seems advantageous in the maintenance of calcium balance. The growth of antlers may therefore be looked upon as part of a mineral saving strategy. The mineral stored in the antler thus represents a reserve to be used during pregnancy and lactation. This is in contrast to the common view that shedding of antlers is just waste of mineral when there is a great need for calcium.


This article's focuses on sexual inequalities of career in the management of four general directions of two ministries, economic and financial, social, contrasted from the point of view of their feminisation and the types of career. The inquiry is based on a hundred or so life stories of both men and women. Above their family education and the unequal access to senior civil service through the royal route of the ENA, the obstacles in the careers of women are detected at the heart of the administration, through the rules of availability, geographical mobility and the homophilic cooptation they imply. Policies of professional equality struggle to modify them but, nonetheless, succeed in creating a greater awareness of the problem.


Anti-β8 integrin monoclonal antibody was employed to detect the expression and location ofβ8 integrin on astrocytes in a oxygen-glucose deprivation(OGD)-reoxygenation model,as well as in kidney and brain in the different time points after postmortem in mice,then a density(mean)- postmortem interval curve was drawn to speculate the postmortem interval of mice.It was showed:the expression ofβ8 integrin on astrocytes,tubular epithelial cells and glial cells was increased in hypoxia.The location ofβ8 integrin transfered from cytomembrane to cytoplasm,and finallyβ8 integrin was released to extracellular matrix along with fracture of cytomembrane.Image-Pro Plus analysis indicated thatβ8 integrin expression of glial cells peaked at 48 h in hypoxia.The curve of density(mean)- postmortem interval was able to speculate the postmortem interval accurately.

Little attention has been paid to the question of how to finance the costs of scaling up MNCH care and the likely availability of funds. Methods Past health expenditure (2000 – 2005) was analysed through the National Health Accounts of 57 high priority countries. They projected likely availability of funding for the period 2006 – 2015 under two scenarios (business as usual and public commitments). We estimated the financing gap by comparing the share of projected total health expenditure dedicated to MNCH with the WHO costing model for scaling MNCH interventions.[HEFP Working paper 01/07, LSHTM, 2007]


Over 100 years ago, before threats such as global climate change and ocean acidification were issues engrossing marine scientists, numerous tropical reef biologists began expressing concern that too much emphasis was being placed on coral dominance in reef systems. These researchers believed that the scientific community was beginning to lose sight of the overall mix of calcifying organisms necessary for the healthy function of reef ecosystems and demonstrated that some reefs were naturally coral dominated with corals being the main organisms responsible for reef accretion, yet other healthy reef ecosystems were found to rely almost entirely on calcified algae and foraminifera for calcium carbonate accumulation. Despite these historical cautionary messages, many agencies today have inherited a coral-centric approach to reef management, likely to the detriment of reef ecosystems worldwide. For example, recent research has shown that crustose coralline algae, a group of plants essential for building and cementing reef systems, are in greater danger of exhibiting decreased calcification rates and increased solubility than corals in warmer and more acidic ocean environments. A shift from coral-centric views to broader ecosystem views is imperative in order to protect endangered reef systems worldwide.


The concept of cultural relativity, developed by anthropologists to induce respect for difference, is often deployed to excuse, rationalize, or explain differential treatment before the law of women, minorities, and indigenous groups and to justify what many call human rights abuses. Accusations of cultural imperialism--regardless of the source--chill the anthropological soul and raise difficult questions concerning research questions and advocacy. Cultural relativity should not be discarded altogether because the reasons it developed as a central theme of American anthropology have far from disappeared and it can be used to defend basic rights. By the same token, some of the ways in which the concept of culture is used also penalize those "minorities" to whom respect may be intended. The author makes an argument for a mediated and partial universalism.


In highly developed countries, the adolescent phase of life is expanding more and more. The consequences are status insecurity and inconsistency. A side effect is that adolescence is no longer clearly separable as demarcated biographical stage from adulthood. In this paper, we argue that the developmental tasks of a typical adolescent and a typical adult can only be partially differentiated, and the exact point in time when adolescents become adults can no longer be clearly identified. We find evidence that adolescence is becoming more 'adult' and adulthood is correspondingly becoming more 'juvenile'. In almost all important social areas of life, the behavioral patterns of adults and of adolescents are coalescing. Living with insecurity in the working life and in social relations, experiencing limitations of personal autonomy, and the continuous need to work on social status inconsistencies today are characteristic features of the life of adolescents and adults. As many adolescents meet these demands skillfully and flexibly, they have in many respects become 'social models' for the adult life phase.

The study was conducted to assess the sympathovagal balance in patients with polycystic ovary syndrome (PCOS) using short‐term heart rate variability (HRV) analysis and conventional autonomic function tests (CAFT).


Post-shot modeling of NIF capsule implosions was performed in order to validate our physical and numerical models. Cryogenic layered target implosions and experiments with surrogate targets produce an abundance of capsule performance data including implosion velocity, remaining ablator mass, times of peak x-ray and neutron emission, core image size, core symmetry, neutron yield, and x-ray spectra. We have attempted to match the integrated data set with capsule-only simulations by adjusting the drive and other physics parameters within expected uncertainties. The simulations include interface roughness, time- dependent symmetry, and a model of mix. We were able to match many of the measured performance parameters for a selection of shots.


Relevance. The study of the dental status, including periodontal, in adolescents with type 1 diabetes, has a high scientific and clinical significance in terms of early diagnosis and prediction of the pathology of the dentoalveolar system in this group of patients.Materials and methods. The study included 54 adolescents with type 1 diabetes aged 14-17 y.o.; of which 44% were boys, and 56% were girls. The duration of diabetes was 71.2 ± 46 months. Oral cavity condition evaluation included an interview and examination using instrumental and index assessment. The index assessment included the Green-Vermilion oral hygiene index (OHI-S), the papillary-marginal-attached index (PMA), Russell's periodontal index (PI) and the decayed-missing-filled index (DMFT). To evaluate the diabetes factor impact on the periodontal tissues, we assessed the level of HbA1c, the duration of DM1, sex, age, and the presence of microangiopathy specific for type 1 diabetes, followed by multivariate regression analysis using JAMOVI 2.3.13 software.Results. The study established that only 11% of the examined adolescents had compensated type 1 diabetes with an HbA1c level <7%. As for the index assessment of the oral cavity condition, most patients had mild or moderate deviations, indicating initial changes, including ones in periodontium. We also established a significant adverse effect of HbA1c increase, i.e., metabolic decompensation, on all studied indices (OHI-S, PI, PMA).Conclusion. Initial inflammatory periodontal changes in type 1 DM may occur at a fairly early age and do not depend on age, sex and the presence of vascular complications, and are associated with worse glycemic control numbers. Dental check-ups of adolescents with type 1 diabetes require periodontal index assessment and collaboration of dentists and pediatric endocrinologists.


Land cover and use changes are important to study for their impact on ecosystem services and ultimately on sustainability. In urban environments, a particularly important research question addresses the relationship between urbanization-related changes and biodiversity, subject to controversies in the literature. Birds are an important ecological group, and useful for answering this question. The present study builds upon the hypothesis according to which avian diversity decreases with urbanization. In order to answer it, a sample of 4245 observations from 650 sites in Annaba, Algeria, obtained through the point abundance index method, were investigated by computing Shannon-Wiener's diversity index and the species richness, mapping them, and analyzing the results statistically. The findings confirm the study hypothesis and are relevant for planning, as they stress the role of urban green spaces as biodiversity hotspots, and plead for the need of connecting them. From a planning perspective, the results emphasize the need for interconnecting the green infrastructure through avian corridors. Moreover, the results fill in an important lack of data on the biodiversity of the region, and are relevant for other similar Mediterranean areas. Future studies could use the findings to compare with data from other countries and continents.

Unpredictable value of carry bit in the summation of carry-sum is an annoying issue preventing carry-sum from being applied to designs with sign extension. In this paper, we propose a methodology to determine the carry bit of the carry-sum form output generated by Booth encoded multiplier without final addition. We discover that this carry bit is a constant "1" in traditional unsigned Modified Booth Encoded (MBE) multiplier, which makes carry-sum form applicable to hierarchy multiplier. Detailed proofs and gate level verification of our discovery is given, and experimental results show more than 20% shorter delay and up to 36% improvement in area-time product compared with non-carry-sum designs.


We present first observations of OH and (HO2 + RO2) carried out in Antarctica outside the summer season. Measurements were made over 23 days in spring at the coastal Antarctic station Halley. Increases in concentrations were evident during the measurement period due to rapidly increasing solar irradiance, and clear diurnal cycles were present throughout. There were also notable differences in air mass composition depending on wind direction. Air masses that had traversed the sea ice zone had both higher concentrations of OH and a larger OH:(HO2 + RO2) ratio. We use steady state kinetic arguments and a 0‐D box model to probe the chemical drivers. We find that differences in bromine chemistry, previously measured at Halley, are sufficient to account for the observed differences in OH concentration as well as the ratio. There is some evidence also that chlorine chemistry is influencing concentrations of RO2.


In this work in progress paper I present preliminary evidence from ongoing research that suggests that the organization of current pedagogy in short class sessions leaves prevents students from engaging in a dialogue and is partly responsible for student disengagement from engineering. I draw on theoretical literature on dialogic inquiry and preliminary data from analysis of two different classes to show that engineering classes are often characterized by lack of joint meaning making and knowledge construction at the expense of information delivery. I argue that our current use of technology often exacerbates and compounds the problem and prevents conceptual learning. I suggest that a potential solution is to revise our understanding of the role of dialogue and the use of technology and design for dialogic inquiry so that language - verbal and written - and representations - such as free-body diagrams - that play a central role in leading to internalization of concepts are the primary focus. It is critical for us to engage students in the act of representing and not just being exposed to semiotic representations. Dialogic learning can increase innovative thinking and creativity.


Financial distresses have strong relationships with the company's bankruptcy. The financial distress can be predicted by using information contained in the financial statements and the company's corporate governance mechanisms. The purpose of this study is to prove the effect of ownership structure, liquidity ratios, leverage ratios, activity ratios, and the size of the company to possible financial distress of manufacturing companies in Indonesia Stock Exchange. Populations of this study are manufacturing companies in Indonesia Stock Exchange, which are published in the financial statements from the years 2008-2012,samples of the research  are 156 financial. Data analysis uses a logistic regression .The results of this study indicate that managerial ownership significantly influence of financial distress. While institutional ownership does not significantly influence of financial distress. Liquidity ratios and activity ratios significantly influence of financial distress. While the leverage ratio and firm size had no significant effect on the financial distress. The results can be used for decision making corporate leaders and investors as well as potential investors to always attention Managerial ownership, liquidity ratio, and the ratio of the activity, because these three variables has a contribution in influencing the potential for financial distress.


This study seeks to evaluate the potential benefits of high doses of ambroxol treatment for acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) by conducting a meta‐analysis based on randomized controlled trials (RCTs). We searched the Pubmed, Embase, China National Knowledge Infrastructure, and Wanfang databases through December 2013. Only RCTs evaluating high doses of ambroxol (≥15 mg/kg or 1000 mg/day) treatment for patients with ALI/ARDS were selected. We included 10 RCTs involving 508 patients. Adjuvant treatment with high doses of ambroxol increased PaO2/FiO2 (weight mean differences [WMD] = 69.18, 95% confidence intervals [CI]: 41.71–96.65), PO2 (WMD = 11.74, 95% CI: 8.50–14.99), and SaO2 (WMD = 2.15, 95% CI: 1.60–2.71) compared with usual treatment. Treatment with high doses of ambroxol appeared to reduce serum tumor necrosis factor‐α level (WMD −7.92 µg/L; 95% CI, −10.94 to −4.9) and interleukin‐6 level (WMD = −20.65 µg/L, 95% CI: −24.74 to −16.55) and to increase serum superoxide dismutase level (WMD = 19.07 NU/mL, 95% CI: 6.16–31.97). The findings suggest that treatment with high doses of ambroxol appears to improve PaO2/FiO2, PO2, and SaO2, and the benefits might be related to ambroxol's anti‐oxidant and anti‐inflammatory properties.


Objectives: Pulmonary valve replacement is increasingly performed late after correction of Tetralogy of Fallot. Most reports have dealt with tissue valves as the valves substitute of choice although late deterioration and reoperation are the rule. We aimed to study the mid-term results of bioprosthetic pulmonary valve implantation in the patients with a previous corrective surgery resulting in severe pulmonary regurgitation. Methods: The present cross sectional study was conducted on eighty consecutive patients with pulmonary bioprostheses . After clinical evaluation, all the patients underwent a complete, two-dimensiona and Doppler study. Any regurgitation or stenosis equal to or more than the moderate level was defined as significant. Results: Thirty-four patients (43.6%) had at least one kind of malfunctioning pulmonary bioprostheses;. 24 patients with stenosis (30.8%), 16 (20.5%), with insufficiency and 6 (7.7%) with both. 5- years freedom from bioprostheses dysfunction (defined as significant stenosis or regurgitation) was 56.4%. Most patients (99%) had degrees of right ventricular enlargement and dysfunction. Conclusions: We found less pulmonary valve bioprostheses durability compare to the previous studies. Besides, the 5-year freedom from significant dysfunction (56.4% in our study) was comparable to 10-year longevity (58% in other studies) of pulmonary bioprosthese.


Several fragments obtained from alkaline borohydride degradation of a rat intestinal glycoprotein fraction have been tested for anti‐complementary activity. Oligosaccharide alditols with a molecular weight of les than about 1 ± 103 daltons showed no activity, whereas reduced oligosaccharides in the molecular weight range of about 1 ± 103 to 3 ± 103 daltons exerted a minor conversion of C3 by the alternative pathway. The low molecular weight fragments tested did not influence C3 conversion induced by the intact intestinal glycoprotein fraction. Of the fragments a peptide fraction, with an 'avenge' molecular weight of 2 ± 103 daltons, and peptide‐containing glycoconjugates exerted activation of C3 by both th classical and alternative pathways. Classical pathway activation by the intestinal glycoproteins depended on antibody, whereas alternative pathway activation did not. Alternative pathway activation appeared to require Factor B in that the intestinal glycoprotein induced no C3 conversion in serum heated to 50°C for 20 min. The rat intestinal glycoproteins had no protease activity on casein and no stimulating effect on human lymphocytes in vitro. Branching of oligosaccharide chains was not indicated by the methylation analyses carried out.


A growing number of stakeholders and authorities recognize the benefits of cycling. Much is known already about the nature of cycling and the factors that influence it. The goal of this book is to bridge the gap between research and practice by allowing for that vital transfer of knowledge between researchers and practitioners. Each chapter provides a summary of important outcomes for policy making and outlines the lessons that practitioners can learn from the research. Cycling promotion can only be successful as part of integrated planning approaches.


In wireless sensor networks, sensors must have a high degree of autonomy to ensure a continuous monitoring of the phenomenon perceived and must transmit the best of information to the base station with minimum loss of it. Cluster based routing protocols were initiated as the most energy efficient routing protocols for large scale wireless sensor networks. With the trend of multimedia and real time applications, the quality of service becomes one of the main requirements of WSNs. The purpose of this paper is to compare some cluster-based routing protocols, differentiated in the data transfer strategy, according to some QoS metrics such as: energy, delay, and bandwidth. These protocols are LEACH, CBHRP, MH-LEACH and LEATCH. Simulations results have shown that the best routing protocol is CBHRP because it realizes the best tradeoff between all metrics


Recently, with the different issues encountered in road mobility, the presence and development of the Vehicular Ad hoc Networks (VANETs) have become a necessity. VANETs have various positive impacts on vehicular safety, road security, traffic management, drivers' comfort, and passengers' convenience. However, the expansion in the world's population has led to enormous traffic congestion on multiple roads. This congestion results in uncontrollable delays affecting economics, society and the environment. In this paper, we propose two routing protocols that depend on the Signal to Interference Ratio (SIR), differing from existing ones by introducing a new metric to select the best route from a source to a destination. In the first protocol, we choose the best route based on the maximum level of SIR at each node. Besides, we select the Backup SIR to minimize the number of SIR calculations at the channel update process. While in the second protocol, we design a hybrid Markov chain model composed of two Markov models; the first one aims at predicting the SIR value of the next round, while the second one is an analytical model that targets managing the number of channel update process. In order to validate our solution, extensive simulations are realized in considering the real scenario of the city of Beirut (Lebanon). The results show that our proposed protocols perform better with regard to overhead, packet delivery ratio, throughput and end‐to‐end delay.


This paper investigates the effects of a limited consumer memory on the price competition between firms. It studies a specific aspect of memory---namely, the categorization of available price information that the consumers may need to recall for decision making. This paper analyzes competition between firms in a market with uninformed consumers who do not compare prices, informed consumers who compare prices but with limited memory, and informed consumers who have perfect memory. Consumers, aware of their memory limitations, choose how to encode the prices into categories, whereas firms take the limitations of consumers into account in choosing their pricing strategies. Two distinct types of categorization processes are investigated: (1) a symmetric one in which consumers compare only the labels of price categories from the competing firms and (2) an asymmetric one in which consumers compare the recalled price of one firm with the actual price of the other. We find that the equilibrium partition for the consumers calls for finer categorization toward the bottom of the price distribution. Thus consumers have a motivation to invest in greater memory resources in encoding lower prices to induce firms to charge more favorable prices. The interaction between the categorization strategies of the consumers and the price competition between the firms is such that small initial improvements in recall move the market outcomes quickly toward the case of perfect recall. Even with few memory categories, the expected price consumers pay and their surplus is close to the case of perfect recall. There is thus a suggestion in this model that market competition adjusts to the memory limitations of consumers.


To change the situation of shape memory polymers (SMPs) that can only remember very few shapes and enable discretional morphing for practical application, the authors report a reversible stepless multiple SMP derived from ultrahigh molecular weight polyethylene (UHMWPE). As the crystals of semi‐crystalline polymers are assembled by those with slightly different melting temperatures, and each type of crystal can remember a single shape, the crystalline region of UHMWPE is allowed to remember plenty of temporary shapes after programming. Changing the temperature of the programmed polymer within the melting/crystallization temperature ranges would lead to releasing/recovery of the memorized temporary shapes. Accordingly, multiple shape memory effects can be easily realized without an elaborate design of material structure and training process in advance as before. The temperature‐dependent adjustability of the analog capacitor and soft lens with embedded programmed UHMWPE as actuators, characterized by the continuous/random/proportional responsivity, further reveals the utilization prospects of the controllable reversible stepless discretionary morphing effect. Moreover, the maximum work density of the programmed UHMWPE is found to be 210 kJ/m3, which is more than 10 times of piezoelectric ceramics, so that it can serve as a proof‐of‐concept mechanical driver for reversibly pumping of ethanediol‐droplet upon heating/cooling.


Four samples of syndiotactic poly(propylene) were synthesized by changing either the polymerization temperature or the catalytic system. Samples with different molecular weights were obtained, ranging between 27 000 and 826 000, whereas the fraction of syndiotactic pentads was found very near in the different samples, ranging between 88 and 91%. The polymer powders were quenched from the melt in an ice-water bath, extracted at room temperature and aged for 1 month. Changes in the structural organization during the ageing time at room temperature were followed by X-rays, transport properties and infrared analysis. The X-ray diffrac- tograms showed that all the fresh samples crystallized in the disordered helical form I, containing also a fraction of chains in trans-planar conformation. The helical crystallinity was found very similar for all the samples, and a small increase of this parameter, not higher than 4-6%, was observed during the ageing time. At variance, the study of sorption of a vapor at low activity indicated the presence of an intermediate phase not crystalline, yet impermeable to the vapors, increasing during the ageing at room temperature. The fraction of the intermediate phase was very high in the lowest molecular weight sample, and decreased on increasing the molecular weight, reaching a constant value for molecular weights higher than 80 000. The analysis of the infrared spectra showed that the helical bands increase during the ageing, indicating that the intermediate phase is composed by very small and disordered helical crystals. The elastic modulus of each sample was measured soon after quenching and during the ageing. It was found a consistent increase of this parameter, not ascribable only to the small increase of crystallinity. The increase of the elastic modulus of all the samples was correlated to the increase of the intermediate phase derived by sorption, and a good dependence on this parameter was found.


The pathological changes produced by the virus under investigation are similar to those deemed characteristic of a certain well known group of filterable viruses.


AIM The effect of drug particles on the release behavior of hydrogel matrix tablet of HPMC was studied. METHODS The release behavior of aspirin with different particles was tested. RESULTS When the tablets was made mainly with HPMC and without MCC, the release rate was lower with the decrease of drug diameter in the first 4 h, while from 4 to 24 h the release rate was higher with the decrease of drug diameter. CONCLUSION The release mechanism of HPMC tablets changed when MCC was excluded.=


A battery charger includes a circuit for detecting battery voltage (V1) appeared when a predetermined time (T1) has elapsed after starting a charging operation. The determination as to whether the battery has been fully charged is performed after the battery voltage has reached the sum of a predetermined potential difference (dVS) and the battery voltage (V1).

Seismic phase recognition is the foundation of seismic localization and the essential part of automatic seismic monitoring and processing. How to identify P-wave from large amount of noise data is the key problem here. Accurate automatic processing can manage large amount of data, so as to free up manpower. We trained a deep neural network (DNN) to identify P-waves from noises. In order to reduce the training dataset amount and improve the performance of the network, we introduce short-time Fourier transform (STFT) at front-end of the network, which not only retains the data information, but also makes the characteristics more obvious which reduces the burden of the network. The results show that for dataset of regional and distant earthquakes, recall ratio for p-wave is 90% on the average, and precision ratio is around 70%, indicating that DNN along with appropriate signal processing such as STFT perform well in P-wave identification.


In a recent work of an elaborate kind, displaying much ability, its author, Dr Richardson, has endeavoured to prove that the cause of the coagulation of the blood is of a chemical nature, and referable to the escape of a volatile matter, and that the volatile matter is ammonia. It is not my intention at present to consider the various circumstances which he brings forward in favour of his conclusion. I shall restrict myself to a few observations which I have made, the results chiefly of trials instituted for the purpose of testing his speculations, and of satisfying myself, if possible, on the subject.


ABSTRACT Purpose: The purpose of this research was to test the feasibility of a new pain and fatigue self-management technique, bilateral stimulation and desensitization (BSD), in fibromyalgia (FM). Methods: This mixed methods study contained a pilot randomized trial and a qualitative feedback assessment about using BSD as obtained from participant interviews. Twenty-nine subjects were recruited. Participants were mailed a BSD demonstration video, duplicate written instructions, and an mp3 file of the audio BSD technique. Online diaries tracked pain, fatigue, and intervention use. Results: Post-enrollment attrition was 17.2%. Although pain and fatigue reduction were non-significant (p < .10), effect sizes were medium to large (d = .69–.72). In addition, pain catastrophizing was significantly reduced (p = .03; d = .80). Diary data showed significant reductions in fatigue and pain (p < .02) and participant usage of the BSD technique from 4.5 to 4.7 times/week. Twelve out of 14 (85.7%) interviewed subjects rated the program favorably for its convenience and effectiveness. Low-frequency side effects were reported for the BSD techniques of finger taps and sounds. Conclusion: This development study showed initial feasibility of a brief self-management intervention that may show potential to reduce pain and fatigue in FM.

In Denmark, as in most other European countries, there is a net migration from the less urbanized to the more urbanized parts of the country. This article summarizes the results of a Danish study on the extent and composition of migration flows; and on factors and conditions that have a decisive influence on migration to fringe areas. The study shows that a considerable share of movers to the fringe areas in Denmark can be characterised as income-transfer mover. They are people without employment moving to get lower housing costs. But there are also groups of people moving to employment in the areas, going back to places where they have grown up or moving to better housing conditions in a more natural environment.

The nature of diffusivity and porosity in crystalline rock was studied by electrical conductivity measurements, steady-state diffusion experiments, saturation-leaching of tracers with cylindrical rock samples and analysis of the concentrations of different elements from core samples or pore water near fractures. The phenomena of main interest were dead-end porosity, ion-exclusion, sorption, and the continuity of pore networks. The modelling of experimental results was based on a modified Fick`s second law for diffusion, which was solved either by analytical or numerical methods. The measured D{sub e} and {epsilon} were found to statistically follow an exponential presentation: Archie`s law. The existence of ion-exclusion for anions was confirmed. The connectivity of the pore network extended in the laboratory experiments at least six centimetres, in coarse of the pore network extended in the laboratory experiments at least six centimetres, in coarse-grained granite in nature several metres but in fine-grained rock samples of a uranium deposit the element mobilization effects could be seen only to the depth of 2-3 centimetres.


BACKGROUND
An outbreak of trichinosis involving a cohort of 33 returning travelers from a resort island in a neighboring country was suspected, beginning with 2 initial cases who were hospitalized with a syndrome of fever, myalgia and eosinophilia.

METHOD
At the initial visit, a full history was obtained and a physical examination was performed for each individual. Also, blood was drawn for full blood count, blood film for malaria parasites and Trichinella serology. Extensive epidemiological investigations identified a total of 84 returning travelers from 6 separate groups, of which 58 (69%) were subjected to a detailed interview, including the kinds of meat consumed on the island.

RESULTS
Twenty-five of these 33 persons (75.7 %) fulfilled clinical or serological case definition criteria for trichinosis. IgG antibody for Trichinella spiralis was detected in 8 out of 32 persons who had the test done (25%). Symptoms were generally mild, with only one patient (3%) requiring steroids for prolonged myositis.

CONCLUSION
We suspect this outbreak to be due to trichinosis although the source could not be identified. Extensive epidemiological investigations identified a total of 84 returning travelers from 6 separate groups, of which 58 (69%) were subjected to a detailed interview, including the kinds of meat consumed on the island, but the source of the outbreak could not be identified.

At present, the energy from renewable sources is an important element of the sustainable development strategy of the European Union (strategy covering the period until 2020). The article presents the role of renewable energy in the structure of primary energy sources and total energy production. In order to evaluate the present-day role of the renewable energy sector, specific European Union states were analysed, with particular focus on Poland, the country whose results were juxtaposed with the average ratios established for the EU-28. A detailed analysis of the current facts was performed (also a forecast for the period running up to 2020 was made), where particular energy sources were distinguished in the renewable energy production structure. A special role among renewable energy sources was ascribed to solar energy, wind energy, hydropower, geothermal energy, biogases and biofuels. The conclusions drawn from the research point out to the fact that the development of renewable energy in Poland is growing slowly but surely. In 2011, the share was at 9.5% and by 2015 it grew to 11.8%, with the target set for 2020 being at the level of 15.0%. The production of energy from renewable sources is improving (from 7.5 to 8.1 Mtoe). Nevertheless, the share of primary energy obtained from renewable energy sources in the total primary energy is less than half of the EU share. The data showcase that the projected aim is likely to be achieved; however, the few years to come should envisage some intensification of activities oriented to this goal. Biomass now enjoys the dominant role but its significance is gradually waning, which favours wind energy and biofuels. The projected directions of renewable energy development indicate that this sector is going to be a significant factor in implementing the sustainable development policy in the years to come.

The present study approaches the subject of the use of licit and ilicit drugs, discussing,
more specifically, two consumption forms: the experimentation and the eventual use.
We hypothesized that there are individuals who try or use drugs eventually don't
become dependent. Somehow, those individuals have specific points on theier development,
wich work as protective factors. So the dependence doesn't settle down. The study of those
individuals' family context was privileged. Experiences lived in the family routine, can have
contributed to the non-addictive behavior. Among those experiences, were outstanding the
self-esteem, responsability and limits.
The qualitative work was developed in a community of low income in the city of Rio
de Janeiro. Individuals were interviewed with history of experimentation or/and eventual use
of drugs licit and illicit, but they didn't develop dependence.
The results seem to confirm the hypothesis that self-esteem, responsability and limits
skilled in the daily family can constitute important protective factors against the dependence.
Besides, the study shows the need of new investigations in the histories of drug dependent's
life and individuals users who are not dependent. Those studies would allow to enlarge the
discussion about protective factors and risk factors, not only related to the consuption of
drugs, but also on the behaviors of preservation of the health and quality of the life.


This study aimed to assess the associations between menstrual characteristics and the prevalence of metabolic syndrome (MetS) and non‐alcoholic fatty liver disease.


Existing technologies, institutions, and behavioral norms together act to constrain the rate and magnitude of carbon emissions reductions in the coming decades. The inertia of carbon emissions due to such mutually reinforcing physical, economic, and social constraints is referred to as carbon lock-in. Carbon lock-in is a special case of path dependency, which is common in the evolution of complex systems. However, carbon lock-in is particularly prone to entrenchment given the large capital costs, long infrastructure lifetimes, and interrelationships between the socioeconomic and technical systems involved. Further, the urgency of efforts to avoid dangerous climate change exacerbates the liability of even small lock-in risks. Although carbon lock-in has been recognized for years, efforts to characterize the types and causes of carbon lock-in, or to quantitatively assess and evaluate its policy implications, have been limited and scattered across a number of different disciplines. This systematic review of ...

This paper explores the impact of Italian Futurism on the Ukrainian art discourse through a focus on the Panfuturist group. The Ukrainian Panfuturists of the early 1920s saw themselves as the only legitimate successors to Italian Futurism, a movement which, in their eyes, was already passé. Leftist and radical, they perceived Panfuturism, like Communism, as "the end of all the -isms". The activities of the Ukrainian Panfuturists ranged from rude manifestos to sophisticated theoretical essays, visual poetry and "poetry-fi lms". Attempting to install themselves in the network of the avant-gardes, these Ukrainian modernists not only claimed to be the only true Futurists, but also, positioned themselves as allies of the German and French Dadaists. In this way, they emphasized their dissociation from Moscow, which was crucial to their identity. This paper argues that the modernist revival in Ukrainian literature and visual arts in the 1920s and early 1930s was profoundly shaped by a critical adoption of Futurist theory. The outcome of the Ukranian modernists' appropriation of Italian Futurism was discernible in their use of topics such as aviation, machines, radio broadcasts etc., and in their adoption of poetic devices such as "parole in libertà". In the visual arts, it inspired the artists to refl ect on the interaction between the work of art and the viewer, and to embark on a path of abstraction, dynamization and synaesthesia. The Ukrainian answer to Futurism also entailed a theory of destruction, which was to become the foundation of art in the "transitional period". Inspired by the Italian Futurist movement, this group of Ukrainian artists and intellectuals regarded itself as an activist intellectual community aiming for a radical reform of art and society.


Polymeric resins have been widely used in water treatment processes due to their advantages, such as high selectivity and possibility of regeneration and chemical modification, allowing obtaining a material with greater selectivity/specificity. In the present study, porous polymeric resins of methyl methacrylate-divinylbenzene (MMA-DVB), styrene-divinylbenzene (Sty-DVB) and sulfonated styrene-divinylbenzene (S-Sty-DVB) were synthesized, characterized and evaluated for their efficiency in removing oil and aniline contained in water. In the tests with oily water, the efficiency in removing oil and cations of sodium and calcium was assessed with columns containing only one type of resin (Sty-DVB or S-Sty-DVB) and columns containing blended filling (MMA-DVB/S-Sty-DVB and Sty-DVB/S-Sty-DVB). The columns containing the mixture performed better, due to the diverse hydrophilicity of the adsorbent system, allowing removal of a wider range of contaminants. The removal of aniline from the water was possible with the use of the sulfonated styrene-divinylbenzene because of the reaction between the aniline and acidic sites of the resin. The efficiency of this resin in removing aniline declined gradually rather than abruptly, due to the interaction of the aniline molecules with the aniline salt formed after saturation of the resin's acidic sites.

The self-assembled monolayers (SAMs) of organosilanes formed on an oxide substrate are thought to have a polymerized –Si–O–Si– network due to the homocondensation of silanols of hydrolyzed silane headgroups, which is the most significant difference in the SAMs of organosilanes in comparison with those of alkanethoils and organophsosphonic acids. In order to explore the interface chemistry of organosilane SAMs, surface-sensitive time-of-flight secondary ion mass spectrometry (ToF-SIMS) was used to compare ion fragmentation differences between the SAMs of octadecyltrimethoxysilane (OTMS) formed on a SiO2 substrate and free OTMS molecules, as well as oxide substrate. The ability of ToF-SIMS to verify the hydrolysis of the methoxy groups of OTMS molecules and to assess the polymerized –Si–O–Si– network in their SAMs was demonstrated, which shows that ToF-SIMS provides unique information to help us understand the interface chemistry of OTMS SAMs formed on oxides.

Background/Aim: There is rapid progression and widespread use of patient-derived tumor xenografts (PDX) in translational pancreatic cancer research. This study aimed to establish a liver transplant PDX model using cryopreserved primary pancreatic ductal adenocarcinoma (PDAC). Patients and Methods: Primary PDAC from 10 patients were cryopreserved and transplanted into immunodeficient mice using the liver pocket method. H&E staining and immunohistochemical staining, such as Ki-67, p53, Smad4, and MUC1 were used to evaluate engraftment and histological similarities. Results: Patient-derived xenograft placement was successful in six cases (60%), and 10 mice (33.3%). The Ki-67 index of primary PDAC and the cryopreservation duration were significantly related to successful engraftment (p=0.003 and p=0.007, respectively). Conclusion: In this study, we succeeded in establishing a liver transplant PDX mouse model as a preclinical platform. The successful engraftment was affected by the cryopreservation duration and could be detected by the Ki-67 index.


The consumption of sports and leisure apparel has distinct historical characteristics. It is linked to social fashion and fashion trends, which is an internal expression of college students' perceptions of sports connotation, aesthetic taste, and community affiliation. Furthermore, it serves as a vital link and conduit for college students' perceptions of sports fashion. This research includes fieldwork in a sportswear briefing and a thorough interview with 15 interviewees. This research builds an analytical framework for the relationship between sports, leisure clothes, and college students' consumption behavior based on the conspicuous consumption theory. This article examines the relationship and influence between college students' consumption behavior and sports and leisure clothing consumption in three categories of community affiliation, perceived value, and consumption behavior. According to the findings, college students' consuming activity shows off their affluence to a certain extent. But, at its core, college students' consumption is about understanding society and constructing their self-image. As a result, it reflects the changing value orientation of today's Chinese college students' purchasing habits. According to the research, it shows the importance of sports leisure apparel consuming behavior is rooted not only in the clothing but also in community identity.


The lateral hypothalamic area was topically stimulated in awake cats via chronically implanted electrodes. From dorsolateral hypothalamic"feeding center" localizations it was possible to elicit a facilitatory influence on unconditioned and conditioned behavior responses connected with the approach of food, while at the same time intestinal motility was enhanced by the stimulation. The extent to which a fully developed feeding response was elicited by the stimulation was dependent on the degree of satiation of the stimulated animal. From ventrolateral hypothalamic"alarm area" localizations even weak electrical stimulation interfered strikingly with conditioned feeding responses and produced short-lasting inhibition of the prevailing intestinal motor activity.

8.1 Existence theorems. A chain (path) in a graph G (digraph D) is called eulerian if it uses every edge of G (are of D) once and only once. Eulerian chains arose from the Kl nigsberg bridge problem, which asked whether the townspeople in Königsberg could traverse a series of bridges, going over Bach once and only once, and returning to the starting point. In the course of showing this was impossible, Euler produced techniques which gave birth to graph theory. In today's world, the notions of eulerian chain and path are applied to such problems as routing street-sweeping and snow-removal vehicles, untangling genetic information, and designing telecommunications systems. We shall investigate these applications in this chapter. It will be useful in this chapter to allow a graph or digraph to have more than one edge or are hetween vertices. W c shall use the terms multigraph and rnultidigraph to make it elear that multiple edges and ares are allowed. Loops will also be allowed. The notions of chain. path, etc. are unchanged (though the definition now sometimes allows a, b, aas a circuit). We stils define a chain or path as eulerian if it goes through each edge or are once and only once. If a multigraph bas an eulerian closed chain, then it must be connected up to isolated vertices. Moreover, since an eulerian closed chain must leave every vertex as often as it enters, each vertex must have ever-_ degree, where the degree of a vertex is the number of edges joining it. THEOREM 8.1. A multigraph G has an eulerian closed chain if and only if G is connected up to isolated vertices and every vertex has even degree. Figure 8.1 illustrates this theorem. Ever\, vertex of the multigraph G has even degree. An eulerian closed chain is the following: a, b, c. b, c, d, a. e, d, f. a. For a proof of Theorcm 8.1, see for example Harary (1969). TI-LeoREM 8.2. A niultigraph G has an eulerian chain if and only if G is connected up to isolated rertices and the number of vertices of odd degree is either 0 or 2. To illustrate this theorem, note that the multigraph of Fig. 8.2 has an eulerian chain a, b, c, d, a, c, d, but no eulerian closed chain since vertices a and d have odd degree. If D is a multidigraph the …


This chapter details how, after the rise of Indian tea triggered a collapse of its Chinese rivals, the Chinese trade underwent its own crisis of economic principles in the 1890s. It provides an overview of economic ideas during the high age of the Qing Empire, which entailed a sophisticated grasp of economic growth revolving around the utility of the soil and the importance of trade. The stimulus of competition from South Asian tea, crystallized in the crisis, pushed Qing thinkers to abandon dominant mercantilist notions of wealth as something acquired through overseas trade and instead visualize it as something produced by labor. Indeed, global competition compelled a minority of Qing officials to see wealth as something socially determined, originating from the skill and productivity of human activity, hence capable of infinite expansion through innovation. The economic thinker and Qing bureaucrat Chen Chi was exemplary of this transformation. He penned an influential memorial on reviving the tea trade, with much of his analysis tied to a simultaneous engagement with the translated works of English economist Henry Fawcett, ultimately arriving at the same classical tenets of "value" outlined by W. N. Lees in India.


Aim: The purpose of this research was to compare the microleakage of different root-end filling materials. Materials and methods: Thirty human single-rooted teeth were decoronated at the cementoenamel junction, shaped with protaper rotary files, and obturated. About 3 mm apical resection of the roots was carried out and 3-mm deep root-end cavities were prepared using an ultrasonic retro-tip. The root-end cavities were then retrofilled with mineral trioxide aggregate (MTA Angelus) and biodentine, respectively, and submerged in 2% methylene blue dye for 24 hours. The depth of dye penetration and microleakage in each sample were recorded using a stereomicroscope. Results: Higher mean microleakage (mm) was recorded in MTA (2.40 ± 0.63) when compared to biodentine (1.60 ± 0.63) and the difference between them was statistically significant. Conclusion: Both the tested materials showed microbial leakage. Root-end fillings with biodentine had the lowest microleakage and better marginal adaptation as compared to MTA. Clinical significance: Biodentine showed better marginal adaptation and sealing ability when compared to MTA and can be considered as an alternative to MTA as a root-end filling material.


A novel, omnidirectional, nanomaterial-based sensor technology which can provide wide area damage detection of composite structures was proposed in this work. The behaviors of the buckypaper sensors subjected to both tensile and low-velocity impact were investigated. The experimental results showed that the rectangle buckypaper sensor has a large range of sensing coefficients from 21.40 to 35.83 at different directions under tensile. However, the circular buckypaper sensor has a steady sensing coefficient of about 155.63. Thus, the circular buckypaper sensor as a kind of omnidirectional sensor was chosen to monitor the impact damage. The low-velocity impact damage of composite structures is characterized by the gauge factor of omnidirectional buckypaper sensors and the results of C-scanning. Omnidirectional buckypaper sensors' electrical resistance increases with repeated impact loading; composite structure elastic deformation and damage evolution can be identified from resistance change. Experiment results show that structure monitoring based on the omnidirectional buckypaper sensor not only can detect small barely visible impact damage flaws and the damage evaluation of composite structures subjected to impact but also can determine the location of low-velocity impact damage through the analysis of results. Through comparison with C-scan, the results have preliminarily demonstrated that the omnidirectional carbon nanotubes' buckypaper sensor can serve as an efficient tool for sensing the evolution of impact damage as well as serve structural health monitoring of composite structures.


The models of Schnute and Deriso are compared with a simple autoregressive model (SA model). Comparisons are made using both stepwise and omnibus prediction. In the latter case predictions are made for at least 3 or 10 yr ahead. The SA model is shown to be consistently better at predicting both catch and catch-per-unit effort than either of the other two models. Furthermore, the percentage error is frequently sufficiently small to make the predictions useful for stock assessment. It is shown that in practice the Schnute and the Deriso models are variants of the SA model. It is suggested that catch and effort data cannot be used to establish equilibrium catches. The reasons for this are that unique equilibria probably do not exist and the catch/effort data are generally too unreliable to detect anything except major fluctuations in population size. It is suggested that catch-and-effort data can be used by adopting strategies designed to track the population fluctuations.

ABSTRACT: Holistic care is an area that is increasing in small animal nursing and there could be similar benefits to equine patients. The authors discuss the potential benefits of massage as part of a holistic care system of nursing and consider the potential for reduction of morbidity associated with hospital in-patient admissions. Massage has supporting evidence for it's use in stress reduction and we propose the reduction in stress by massage could be associated with improved wound healing, drug uptake from the gastro-intestinal tract and beneficial effects on the immune system, as well as health and safety for the horse and handlers.


Flunarizine markedly depressed vestibular activity in rabbits. The vestibular effect was also evaluated in a double-blind multiple cross-over study in human volunteers, using cinnarizine as a reference drug. Dosage was 10 and 30 mg of e and 15 and 45 mg of Flunarizine cinnarizine. Electronystagmographic tracings were taken at different time intervals after drug intake. There was a good correlation between nystagmus duration and peak velocity of the slow nystagmus phase. At 2.5 h, both doses of flunarizine were more active than cinnarizine 15 mg. When the results of all cinnarizine tests were compared with those of flunarizine, there was a significant difference in favour of flunarizine.


There was a continuing debate about the humanity and scientificity of pedagogy in Germany and a great dispute on the nature of the pedagogy took place in 1960s.The well-known educationist Wolfgang Brezinka raised the debate was pushed to the front of the debate.This paper examines the two important aspects of Wolfgang Brezinka's educational thoughts:an emphasis on value-free in educational science in order to establish a causality-focused system of educational science;an emphasis on value-imparting,even value indoctrination in educational philosophy in order to ensure the stability of the individual personality and shared value in society at the minimum level.It points out that the two aspects show a change from pedagogy to educational science and a change from educational science to pedagogy,which does not contradict but complement each other.The educational thoughts of Brezinka,with its viability and new-conservatism tendency,reflect a response of German pedagogy to the scientific era and the pluralism of value.


The paper describes the influence of the marine erosion and slope instabilities on cliff retreat in the coast near Stara Baška settlement on Krk Island (northeastern channel part of the Adriatic Sea). The bedrock is occasionally covered by breccia from Quaternary period. The coast around Stara Baška is exposed to wave attack and thereby to marine erosion. By comparison of orthophoto maps from 1966 and 2004, the significant coastal retreat was determined. This phenomenon has been a fundamental trigger off different instability phenomena. The type of instabilities is a consequence of the local geological fabric and rock mass resistivity marine erosion. In the investigated area, rock falls and slumps prevail in cliffs formed in breccia. Extremely high tides with the combination of strong waves from southern direction have a significant influence on the coastal erosion. This is an indicator of the possible higher hazard degree caused by the sea-level rise.


The expansion of community forestry practices since the late 1970s and, recently, outmigration have led forest cover to increase in Nepal's mid-hills catchments (>52% of the 4.3 million ha). The catchments traditionally provide food and income for local communities, and they are increasingly important for ecological functions, particularly downstream water use. While the hydrological effects of increasing forest cover are generally unclear in the mid-hills region, mismatched perceptions of forest–water relationships between sections of Nepalese society and scientists challenge the management of the catchments in meeting traditional community needs and growing water demand sustainably. This paper shows the prevalence of the culturally formed notion of "more forest–more water" within broader Nepalese society and the conservation-centric attitude of forest policymakers, who focus on reforestation and afforestation. These perceptions contradict general scientific evidence that shows forest development reduces catchment water yield. Conversely, the results of semistructured interviews (n =150) conducted among members of community forest user groups (CFUGs) in the Roshi Khola catchment of the mid-hills district Kavre showed that 44% of respondents consider that forests contribute to increased water quantity, and 37% think forests decrease it. Furthermore, the respondents that viewed forests as reducing water quantity disliked pine forests because these allegedly caused the reduction. Interestingly, there was a positive correlation between the duration of membership in the CFUG and the perception that forests increase water. Thus, while there is a high research need to understand the forest–water relationships in the mid-hills, extensive communication of research results and deliberation about them are crucial to developing widely acceptable plans for managing the catchments. This is particularly important in the context of expanding community forestry practices and the current debate on scientific forestry presented by Nepal's key forestry documents, including the Forestry Sector Strategy 2016–2025 and Forest Policy 2019.

It also operates with a 16 gain-step VGA to enable re-configurable and direct-frequency modulation at 60GHz with 2562 states (1.1° angular and 0.0007 magnitude resolutions) and −31dB static EVM for multiple PSK/QAM modulations. The modulator uses 0.33mm2 core area in 90nm CMOS and consumes 10mA at 1V.


The Arabian camel (Camelus dromedarius) evolved as a foregut fermenter herbivore with the capacity to utilize fiber-rich diets. As a browsing animal, the camel spends time foraging and selects its own diet from available shrubs and trees that are often rich in antinutritional secondary compounds, which makes them unpalatable for many other species of animals. This feeding behavior reduces the competition for feed resources with other domesticated animals, particularly ruminant animals and horses. It is important to emphasize that the Arabian camel belongs to the family Camelidae in the sub-order Tylopoda (Latin: padded foot) and the order Artiodactyla, which is distinct from the sub-order Ruminantia (Fowler, 2008). However, the two related evolutionary lineages share similarities and bear differences due to the parallel evolution they have undergone. The evolution of camelids is dated back to the Eocene epoch, about 40 to 50 million yr ago (Fowler, 2008; Burger, 2016), and the divergence of Tylopoda and Ruminantia occurred early in the evolution process. The first ancestors of both groups were found in North America, as small goat-sized animals with simple stomachs (Fowler, 2008). The development of the compartmental stomach as a storage and fermentation vat occurred during the Miocene epoch. Gut microbiota of the foregut fermenters, such as the camel and the cow, are involved in the digestion and synthesis of essential nutrients, detoxify antinutritional plant secondary compounds, and contribute to health. Knowledge of the microbial composition and function will assist in the management of the host animals to achieve high productivity while maintaining the health and well-being of the animal. Results of our research have established the identity of important bacterial groups, including lactic acid-producing (LAB) and lactic acid-utilizing bacteria (LUB), and cellulolytic bacteria. The different types of protozoa were also determined by microscopic examination. Bacterial diversity was investigated by constructing clone libraries and later by new-generation sequencing technologies and genome analysis. The focus of this article is on the microbial community of the forestomach of the Arabian camel (Camelus dromedarius) to report the results of our research programs over the past two decades and to shed some light on the development in the field.


In this paper, a new formulation of the dynamics of a robotic manipulator work environment is presented. The work environment is modeled in a way that permits the robot transition to and from contact with the work environment to be effectively simulated. This method circumvents the discontinuities inherent in previously proposed models of work environment dynamic models that have, until now, prevented researchers from considering that phase of manipulation

In this research, the influences of the addition of PVP to PVDF-HFP polymers and the preparation of thin films using a solvent casting method were studied. The PVDF-HFP and polymer blend PVDF-HFP/PVP thin films with a nanostructured surface were investigated using scanning electron microscopy, differential scanning calorimetry, nanoindentation, and dielectric spectroscopy. The results showed that the PVP formed a dispersed phase (the poorer conductive islands) in the PVDF-HFP polymer matrix, which reduced its mechanical properties. The crystallinity of PVDF-HFP polymer decreased with the addition of PVP by 7.4%, but the PVP induced the formation of the polar β-phase of PVDF-HFP. Therefore, an improved dielectric response is expected, but it was not significantly improved even though the polar β-phase was detected. The contrasting effect was attributed to less conductive PVP islands on the surface of the PVDF-HFP/PVP polymer blend, which decreased its conductivity.

23 Hackerott et al. (2017) report that Indo-Pacific lionfish "had no apparent effect on native 24 prey communities" (p. 9) on continuous reef-sites of the Belizean Barrier Reef (BBR). 25 Based on a lack of observational evidence, they challenge existing evidence for the 26 effects of predation by lionfish on native prey community structure and assert that 27 previous experimentally measured effects are inflated by "unnaturally high lionfish 28 densities" (p. 10). Managers may mistakenly interpret these conclusions as evidence 29 that invasive lionfish are of little concern and that active management of lionfish should 30 not be a conservation priority. We find the arguments presented in Hackerott et al. 31 (2017) unconvincing and potentially misleading. Here, we seek to re-evaluate their 32 conclusions in the context of the body of work on the lionfish invasion, and clarify advice 33 to marine resource managers in the invaded range. Specifically, we argue that (1) the 34 low lionfish densities observed in Hackerott et al. (2017) are not predicted to cause 35 observable lionfish effects—so the results offer no countervailing evidence; (2) the study 36 design is ill-suited to identify lionfish-induced changes in prey abundance, were they to 37 occur; (3) the analytical methods employed (correlation between lionfish and prey 38 densities) do not represent a BACI design nor offer a reliable test of predatory effects; 39 and (4) the authors minimize potentially important regional management activities that 40 could affect lionfish population densities and mischaracterize the body of lionfish 41 research that has come before. Scientists should rigorously challenge popular scientific 42 narratives. However, the foundation of such challenges must be carefully designed 43 experiments, sound methodology, and conservative interpretation of one's findings. 44

The green biorefinery concept relies on economically feasible processing to achieve a complete utilization of most lignocellulosic biomass components using green technologies. Among the main component of lignocellulosic biomass, lignin is one of the most interesting components since its aromatic nature makes lignin unique. The study presented here was focused on the enhancement of the organosolv lignin produced from olive wood from the point of view of not only operational conditions but also taking into account the purity and contamination of the obtained lignin. The results showed that the amount of lignin recovered in the liquor was strongly influenced by the process temperature. The ethanol concentration presented the opposite behavior with lignin, reaching high yields at low concentrations. Then, the obtained lignins under optimized conditions were analyzed in order to verify their purity. Almost all the obtained lignins presented hemicellulose contamination but there were differences between the pol...


The authors are able to precisely estimate air permeability of sedimentary rocks from thin section images of pore size, geometry and connectivity. Assessment of the regression equations linking two-dimensional pore characteristics with permeability permits insight into the pore-geometric factors which affect permeability. This empirical approach is necessary because a large number of theoretical models exist to explain permeability. Their data serve to reflect the feasible models for sedimentary rocks. In many rocks composite models are necessary inasmuch as several discrete pore-complexes may coexist. In other rocks the pore-complex can be modelled as a uniform quasi-crystalline complex. In that case, sheet-like porosity or tubular throats may connect with large moldic pores. The evolution of a pore network under progressive diagenesis of a uniform petrology with permeability from 0.1 to 1600 m.d., illustrates the changing controls on permeability as pore-geometry evolves.


We propose a generalization of the synthetic controls and synthetic interventions methodology to incorporate network interference. We consider the estimation of unit-specific potential outcomes from panel data in the presence of spillover across units and unobserved confounding. Key to our approach is a novel latent factor model that takes into account network interference and generalizes the factor models typically used in panel data settings. We propose an estimator, Network Synthetic Interventions (NSI), and show that it consistently estimates the mean outcomes for a unit under an arbitrary set of counterfactual treatments for the network. We further establish that the estimator is asymptotically normal. We furnish two validity tests for whether the NSI estimator reliably generalizes to produce accurate counterfactual estimates. We provide a novel graph-based experiment design that guarantees the NSI estimator produces accurate counterfactual estimates, and also analyze the sample complexity of the proposed design. We conclude with simulations that corroborate our theoretical findings.


Partition computation was performed to the motion status of balls in a coal mill,after which the kinetic energy of balls was used to measure and control the coal storage.Moreover,mill operation process was simulated by PFC3D software platform based on discrete element method,so as to analyze the relationship among the coal quality,coal storage and ball motion under certain quantitatively optimized configuration of operating parameters,and to obtain the variation law of real-time kinetic energy of balls with energy consumption by sliding friction and with total work of cylinder wall,which represent the mill working efficiency.Results show that the impact energy obtained by balls in projectile motion is more than that in cascading motion,and the ball kinetic energy can more accurately reflect the real-time variation of coal storage.The method to control coal storage with ball kinetic energy is therefore proved to be feasible.


The UK government has insisted that reconfigured primary care trusts (PCTs) will be free to continue to provide as well as to commission a range of services under its latest reforms. The announcement is part of its response, published last week, to a scathing health select committee report that attacked the reforms as "ill judged" and the policy of contracting out provider services as "incoherent" ( BMJ 2006;332:72, 14 Jan).

Ministers originally said that the PCTs would have to shed all provided services, such as district nursing and family planning, and concentrate solely on commissioning. They later softened this line, saying trusts could …

In time-of-flight PET reconstruction, the algorithms for joint estimation of activity and attenuation (JEAA), such as maximum-likelihood activity and attenuation reconstruction and maximum-likelihood attenuation correction factors, cannot provide quantitative attenuation information due to the scaling problem. Then, for quantitative PET reconstruction, some post-processing is essentially required to make the estimated non-quantitative attenuation information quantitative. In this paper, we propose a post-processing method to estimate a quantitative attenuation image from attenuation factors (AFs) scaled by an unknown factor. The proposed method is based on the mathematical relationship between a scaled AFs and an attenuation image, and estimates then corrects the non-uniform offset (NUO) in the attenuation image caused by the AF scaling. The NUO correction assumes that the supports of activity and attenuation distributions are identical and the attenuation coefficient of the subject is partially known. To prove the concept of the NUO correction, we evaluated through 3-D brain PET simulations the quantitative accuracy of activity corrected for attenuation with using the NUO-corrected attenuation image. The attenuation coefficient of the brain tissue can be approximated well by that of the water, then transmission-less brain PET imaging would be a suitable application of the proposed method. Under a wide range of conditions of counting statistics, the median of the absolute relative error between the reference and estimated activity images was less than 5% within the brain regions. These results show that, under the above-mentioned assumptions, the scaling problem in the JEAA problem was solved with practical accuracy.
