State-selective study of the direct double photoionization of the Ne valence shell

Cross sections for double photoionization of the Ne L shell into the 2s2p{^5 3}P^0} and ^1P^0 and the 2s^02p^6 ^1S^e states were measured for energies from threshold up to 150 eV, using photon induced fluorescence spectroscopy. Both 2s2p^5 channels were observed with comparable magnitude in contradiction to a propensity rule based on the Wannier-Peterkop-Rau theory. A comparison of the summed ^3P^0 and ^1P^0 cross sections with MBPT calculations results in a deviation of 50%.

Computation of relativistic symmetry orbitals for finite double point groups

A program is presented for the construction of relativistic symmetry-adapted molecular basis functions. It is applicable to 36 finite double point groups. The algorithm, based on the projection operator method, automatically generates linearly independent basis sets. Time reversal invariance is included in the program, leading to additional selection rules in the non-relativistic limit.

Using a Double-pass solar drier for drying of bamboo shoots

Three different drying methods, a forced convection double-pass solar drier (DPSD), typical cabinet type natural convection solar drier (CD) and traditional open-sun drying (OSD) were used for draying of bamboo shoots in central Vietnam. During drying the operational parameters such as drying temperature, relative humidity, air velocity, insolation and water evaporation have been recorded hourly. The mean drying temperatures and relative humidity in the drying chamber were 55.2°C, 23.7%; 47.5°C, 37,6%; 36.2°C, 47.8% in DPSD, CD and OSD, respectively. The mean global radiation during all experimental runs was 670 Wm^−2. The result also shows that fastest drying process was occurred in DPSD where the falling-rate period was achieved after 7 hours, in change to OSD where it took 16 hours. The overall drying efficiency was 23.11%, 15.83% and 9.73% in case of DPSD, CD and OSD, respectively. Although the construction cost of DPSD was significantly higher than in CD, the drying costs per one kilogram of bamboo shoots were by 42.8% lower in case of DPSD as compared to CD. Double-pass solar drier was found to be technically and economically suitable for drying of bamboo shoots under the specific conditions in central Vietnam and in all cases, the use of this drier led to considerable reduction in drying time in comparison to traditional open-sun drying.

Double burden malnutrition of preschool children and its association with brain development and milk consumption

Protecting the quality of children growth and development becomes a supreme qualification for the betterment of a nation. Double burden child malnutrition is emerging worldwide which might have a strong influence to the quality of child brain development and could not be paid-off on later life. Milk places a notable portion during the infancy and childhood. Thus, the deep insight on milk consumption pattern might explain the phenomenon of double burden child malnutrition correlated to the cognitive impairments. Objective: Current study is intended (1) to examine the current face of Indonesian double burden child malnutrition: a case study in Bogor, West Java, Indonesia, (2) to investigate the association of this phenomenon with child brain development, and (3) to examine the contribution of socioeconomic status and milk consumption on this phenomenon so that able to formulate some possible solutions to encounter this problem. Design: A cross-sectional study using a structured coded questionnaire was conducted among 387 children age 5-6 years old and their parents from 8 areas in Bogor, West-Java, Indonesia on November 2012 to December 2013, to record some socioeconomic status, anthropometric measurements, and history of breast feeding. Diet and probability of milk intake was assessed by two 24 h dietary recalls and food frequency questionnaire (FFQ). Usual daily milk intake was calculated using Multiple Source Method (MSM). Some brain development indicators (IQ, EQ, learning, and memory ability) using Projective Multi-phase Orientation method was also executed to learn the correlation between double burden child malnutrition and some brain development indicator. Results and conclusions: A small picture of child double burden malnutrition is shown in Bogor, West Java, Indonesia, where prevalence of Severe Acute Malnutrition (SAM) is 27.1%, Moderate Acute Malnutrition (MAM) is 24.9%, and overnutrition is 7.7%. This phenomenon proves to impair the child brain development. The malnourished children, both under- and over- nourished children have significantly (P-value<0.05) lower memory ability compared to the normal children (memory score, N; SAM = 45.2, 60; MAM = 48.5, 61; overweight = 48.4, 43; obesity = 47.9, 60; normal = 52.4, 163). The plausible reasons behind these evidences are the lack of nutrient intake during the sprout growth period on undernourished children or increasing adiposity on overnourished children might influence the growth of hippocampus area which responsible to the memory ability. Either undernutrition or overnutrition, the preventive action on this problem is preferable to avoid ongoing cognitive performance loss of the next generation. Some possible solutions for this phenomenon are promoting breast feeding initiation and exclusive breast feeding practices for infants, supporting the consumption of a normal portion of milk (250 to 500 ml per day) for children, and breaking the chain of poverty by socioeconomic improvement. And, the national food security becomes the fundamental point for the betterment of the next. In the global context, the causes of under- and over- nutrition have to be opposed through integrated and systemic approaches for a better quality of the next generation of human beings.

Assessing the Precision of Compositional Data in a Stratified Double Stage Cluster Sample: Application to the Swiss Earnings Structure Survey

Precision of released figures is not only an important quality feature of official statistics, it is also essential for a good understanding of the data. In this paper we show a case study of how precision could be conveyed if the multivariate nature of data has to be taken into account. In the official release of the Swiss earnings structure survey, the total salary is broken down into several wage components. We follow Aitchison's approach for the analysis of compositional data, which is based on logratios of components. We first present diferent multivariate analyses of the compositional data whereby the wage components are broken down by economic activity classes. Then we propose a number of ways to assess precision

Small-area variation in health care affecting the choice of cesarean delivery: the case of a Colombian health insurer

In the midst of health care reform, Colombia has succeeded in increasing health insurance coverage and the quality of health care. In spite of this, efficiency continues to be a matter of concern, and small-area variations in health care are one of the plausible causes of such inefficiencies. In order to understand this issue, we use individual data of all births from a Contributory-Regimen insurer in Colombia. We perform two different specifications of a multilevel logistic regression model. Our results reveal that hospitals account for 20% of variation on the probability of performing cesarean sections. Geographic area only explains 1/3 of the variance attributable to the hospital. Furthermore, some variables from both demand and supply sides are found to be also relevant on the probability of undergoing cesarean sections. This paper contributes to previous research by using a hierarchical model and by defining hospitals as cluster. Moreover, we also include clinical and supply induced demand variables.

Texte de présentation sur les concepts muséologiques dans leurs rapports avec les systèmes muséologiques actuels responsables de bouleversements: une double hystérie ?

Les concepts, les notions, les langages qui en découlent, sont intimement lies aux systèmes et aux contextes qui alimentent la forme et la vie du musée. Depuis que la question se pose, où va la muséologie qui a emprunté la voie du changement dans les années 70, 80 et 90, une réflexion sur les principaux vecteurs de transformation de l’institution dex fois séculaire s’impose. Bien que la plupart des musées et de ses dérivatifs (60%) possédant une crédibilité dans le monde occidental , malgré les réformes de modernisation introduites ( attention aux publics, presentation améliorée ) demeurent attachés à la tradition qui en determine l’image, on peut affirmer, sans se tromper, qu’un pan considerable de la muséologie de la période post-moderne (20% en terme de volume d’activité ) est à peine reconnaissable, si on se réfère à la periode antérieure à la deuxième moitié du 20ème siècle. Le concept de MUSEE, dans deux champs antagonistes ou complémentaires, selon l’angle d’analyse, soit la muséologie entrée de plein pied dans les industries culturelles de l ‘ère des communications, et la muséologie (ou l’anti-musée) ayant adopté le parti-pris de l’intervention sociale, véhicules de systèmes idéologiques et organisationnels rompant radicalement avec un passé recent, se partageant entre la mondialisation globalisante et les aspirations du mouvement alter-mondialiste puissant dans la tradition associative. Tributaires d’une part des luttes libératrices (60/70), de la contestation des valeurs, d’autre part des technologies (80/90), de la globalisation (90. ), ces musólogies ( systéme binaire ) prennent la vedette à l’aide de changements irréversibles dans l’ordre des functions du musée.
