Authors: Naisseh Matilda , Martinent Guillaume , Ferrand Claude , Hautier Christophe
Published: August 2015

Previous studies have neglected the multivariate nature of motivation. The purpose of the current study was to first identify motivational profiles of parents' own physical activity. Second, the study examined if such profiles differ in the way in which parents perceive their children's competence in physical activity and the importance and support given to their children's physical activity. 711 physically active parents (57% mothers; M age = 39.7 yr.; children 6–11 years old) completed the Situational Motivation Scale, the Parents' Perceptions of Physical Activity Importance and their Children's Ability Questionnaire, and the Parental Support for Physical Activity Scale. Cluster analyses indicated four motivational profiles: Highly self-determined, Moderately self-determined, Non-self-determined, and Externally motivated profiles. Parents' beliefs and support toward their children's physical activity significantly differed across these profiles. It is the first study using Self-Determination Theory that provides evidence for the interpersonal outcomes of motivation.

Published: August 2015

This study examined university students' academic motivation, focusing on individual differences in their sense of identity. The participants were 109 female Japanese students from two private universities (age range = 19–22 yr., M = 19.3, SD = 0.6). They completed four scales: the Multidimensional Ego Identity Scale, the Scale of Students' Attitude Toward Their Classes, the Academic Motivation Inventory, and the Scale of Lecture Self-Evaluation. Correlational analyses assessed the relationships between subscales. Then, path analysis was conducted toevaluate whether sense of identity affected attitude toward classes, academic motivation, and lecture self-evaluation. Differences particularly in psychosocial identity and self-identity accounted for significant variance in the students' attitudes toward classes, academic motivation, and lecture self-evaluation.

Published: August 2015

The purpose of this study was to examine the predictors and trends of gross motor skills in children from low-income families. The participants were 1,460 children ( M age = 8.39 yr., SD = 1.83; K–6th grade) recruited from three Title I schools. The Test of Gross Motor Development–2nd Edition (TGMD–2) assessed motor skills, FITNESSGRAM assessed health-related fitness, and pedometers and accelerometers measured moderate-to-vigorous physical activity (MVPA). Multilevel modeling revealed that TGMD–2 scores predicted aerobic capacity, but no other relationships were found with other Healthy Fitness Zone parameters or MVPA. TGMD–2 performance was 4.8 and 4.7% greater in successively higher grade levels for girls and boys, respectively. In conclusion, TGMD–2 scores predict aerobic capacity and TGMD–2 scores improved between 4 and 5% in older grade cohorts separated by 1 year.

Published: August 2015

This study assessed the relative age effect (RAE) in judo athletes who participated in the Olympic Games from 1964 to 2012. The names and birth-dates of the Olympic judo athletes were collected from open-access websites. Data from male ( n = 1,762) and female ( n = 665) competitors were analyzed separately. Chi-squared tests were performed to investigate REA in medalists, and by weight categories and sexes. When the analyses used semesters to divide the period when the athletes were born, a RAE was found in male heavyweight athletes and male medallists. Thus, in a selected group of judo athletes who had participated at the highest competitive level, RAEs were present in both athletes who won Olympic medals and heavyweight athletes in the male group.

Published: August 2015

This study compared 45 yoga practitioners ( M age = 29.7yr., SD = 6.4) and 45 matched controls ( M age = 29.3yr., SD = 6.2) on the performance of a behavioral task that assessed negative emotion interference during a high- and a low-attentional demand condition, as well as on state and trait anxiety scores. Outcomes were also compared between beginner and advanced practitioners. For the behavioral task, the final sample comprised 36 yoga and 38 control participants. The yoga group presented lower emotion interference in the high attentional condition, compared to the low attentional condition; rated emotional images as less unpleasant, compared to controls; and reported lower state and trait anxiety scores relative to controls. Also, emotion interference in the low attentional condition was lower among advanced practitioners and state anxiety was lower among practitioners attending more than two weekly yoga classes. The results suggested that yoga may help improve self-regulatory skills and lower anxiety. The psychological mechanisms underlying the relationship between yoga and emotion regulation should be further investigated in longitudinal studies.

The Rupa lake area in Lekhnath Municipality of Kaski district, at Rupa Lake basin areas of Nepal was selected to explore the impacts of climate change on livelihoods in term of food security. 20% of the wetland dependent communities constituted of sample household (HHs). Semi-structured questionnaire was taken for focused group consultations. It was found that majority of population (87%) of lake basin is dependent on agriculture for food security. There is a year-round food security for 50% of sample HHs, with 22% of this having surplus food. About 5% of HHs has food security for less than three months where as 19% HHs have food security for more than six months. Within this scenario, over 90% HHs responded to climate change in the form of rise in temperature (74%); unpredictable rainfall (77%); shift in rainfall (64%); and phonological changes (51%). About 74% of households are aware about the effect of climate change and had adopted different strategies to resist against the effect of climate change. Out of the 74% of HHs, more than 50% of the household use chemical fertilizers and agricultural inputs and other means to cope small shop (business), service, labor and remittance against the climate change.International Journal of Environment Volume-4, Issue-3, June-August 2015Page: 11-19
EFFECTS OF ALKALINE SANDY LOAM ON SULFURIC SOIL ACIDITY AND SULFIDIC SOIL OXIDATION
Authors: Michael Patrick S.
Published: August 2015

In poor soils, addition of alkaline sandy loam containing an adequate proportion of sand, silt and clay would add value by improving the texture, structure and organic matter (OM) for general use of the soils. In acid sulfate soils (ASS), addition of alkaline sandy would improve the texture and leach out salts as well as add a sufficient proportion of OM for vegetation establishment. In this study, addition of alkaline sandy loam into sulfuric soil effectively increased the pH, lowered the redox and reduced the sulfate content, the magnitude of the effects dependent on moisture content. Addition of alkaline sandy loam in combination with OM was highly effective than the effects of the lone alkaline sandy loam. When alkaline sandy was added alone or in combination with OM into sulfidic soil, the effects on pH and the redox were similar as in the sulfuric soil but the effect on sulfate content was variable. The effects under aerobic conditions were higher than under anaerobic conditions. The findings of this study have important implications for the general management of ASS where lime availability is a concern and its application is limited.International Journal of Environment Volume-4, Issue-3, June-August 2015Page: 42-54
ASSESSMENT OF RIVER WATER QUALITY USING MACRO-INVERTEBRATES AS INDICATORS: A CASE STUDY OF BHALU KHOLA TRIBUTARY, BUDHIGANDAKI RIVER, GORKHA, NEPAL
Authors: Rana Anju , Chhetri Jeevan
Published: August 2015

Macroinvertebrates are widely considered as indicators of water quality. The present research work was conducted in Bhalu khola, a tributary of Budhigandaki River, Nepal, to identify water quality using macro invertebrates with Nepalese Biotic Score (NEPBIOS), and examine its applicability by comparing with Water Quality Index (WQI).The diversity of macro invertebrates in the studied river was high as depicted by Shannon Wiener Diversity Index. Altogether, 103 macro invertebrates were identified from 11 families and five orders. There were no dominant species, and most of the species were in clumped distribution. According to NEPBIOS index, river water was found to comply with the characteristics of WQ class I-II that means water quality of the river was good. Other indices such as Hilsenhoff and Lincoln quality index (LQI) index also supported this result. Similarly, water quality index (WQI) also showed similarity with NEPBIOS index, indicating water appropriate for drinking purpose. Thus, it is concluded that the macro invertebrates can be used as economic tools for determining water quality of streams and rivers as efficient water quality indicators.International Journal of Environment Volume-4, Issue-3, June-August 2015Page: 55-68

Published: August 2015

Dust is one of the significant air pollutants in ambient air of Chandrapur industrial cluster. A study was carried out to ascertain the dust fall rate in four sampling locations in the Chandrapur industrial cluster of Chandrapur district, central India. The sampling was carried out by dust fall jar method in winter season (2014-2015) and dust fall rate was estimated gravimetrically. Maximum dust fall rate was recorded in Nakoda 246.67 MT sq km-1 month-1 (industrial area, downwind direction), followed by CSTPS colony 171.77 MT sq km-1 month-1 (industrial area, downwind direction) whereas minimum concentration was found in Babupeath 55.54 MT sq km-1 month-1 (residential area, downwind direction) for December-January. Whereas, during sampling period of February-March maximum dust fall rate was observed to be 278.14 MT sq km-1 month-1 at Babupeath (residential area, upwind direction) and minimum dust fall rate was observed at Ballarpur 173.74 MT sq km-1 month-1 (industrial, upwind direction). The results indicated that dust fall rate for the sampling period of December-January in industrial cluster region was higher as compared with residential region. It has been also observed that upwind direction sampling locations had lesser dust fall rate as compared with downwind direction. The composition of dust fall from study area was dominated by water soluble components. Water insoluble components were comprised of inorganic insoluble and volatile matter. Total inorganic component per cent by weight was maximum in dust.International Journal of Environment Volume-4, Issue-3, June-August 2015Page: 96-110

Authors: Ali Khalafalla A.
Published: August 2015

Two parents with contrasting characters were used, viz; Gd2002SPSN.29 and Ziraa-9 described as (P1) and (P2) respectively. They were selected from the sesame breeding program, Gedarif Research Station, ARC, Sudan. In season 2004 the two parents were crossed to produce F1 hybrid. In season 2005 parents and their F1 were grown. Part of the F1 was selfed to produce F2 and the other part was back crossed to both parents to produce Bc1 and Bc2 progenies. In season 2006 the parents (P1, P2), and their F1and F2 and back crosses (Bc1, Bc2) populations were evaluated in a randomized complete block design with three replicates. A wide range of variability was exhibited for most of the characters. The highest seed yield was obtained by the BC2 (714 Kg.ha-1), while the lowest was obtained by the BC1 (286 Kg.ha-1). Considering the nature and magnitude of gene action, improvement of days to 50% flowering, days to maturity, plant height, number of branches plant-1, height to first branch, height to first capsule, capsule length and 1000-seed weight could be achieved through simple pedigree method while hybrid breeding would be most effective for seed yield plant-1 and seed yield.ha-1International Journal of Environment Volume-4, Issue-3, June-August 2015Page: 111-120
IMPACTS OF WETLAND DEGRADATION IN NIGER DELTA NIGERIA AND ITS SIGNIFICANCE IN FLOOD CONTROL
Authors: Loveline Enwere Chidimma
Published: August 2015

Wetlands perform a wide variety of functions that include flood control, ground water recharge, shore line stabilization, storm protection and climate moderation. However, despite these huge wetland functions, it has witnessed poor appreciation and dreadful conditions. Niger Delta has witnessed constant coastal erosion and rising sea level, this has led to large portions of the landmass being eroded. This paper aims to review some environmental effects of flooding in the Niger Delta region of Nigeria to provide the desired knowledge of role that wetlands play in reducing flood impacts. However, having witnessed the flood, the experience opened my eyes to the environmental challenges facing Niger Delta with respect to Wetlands degradation, poor perception of wetland values and functions, poor environmental practices and non-implementation of environmental regulations. This memorable experience rekindled the desire and motivation to seek a solution to wetland degradation with the aim of recognizing significance of wetlands at the centre of achieving both livelihood and biodiversity improvements to address coastal flooding problem.The study therefore concludes that wetlands are very significant in flood control and thus the conservation and restoration of wetlands, should put in place measures to reduce wetland destruction.International Journal of EnvironmentVolume-4, Issue-3, June-August 2015Page: 177-184

Published: August 2015

The study was conducted to know the status of water quality of the Ramna, Crescent and Hatirjheel lakes in the Dhaka city. Water samples were collected from three different points of each lake and analyzed for various physicochemical parameters including temperature, pH, EC, TDS, DO, BOD, hardness, alkalinity, acidity during the period from November 2013 to April 2014. The mean temperature 22.54, 24.59 and 24.24°C; EC 15400, 282.00 and 618.27 ?Scm-1; TDS 85.38, 155.60 and 339.90 ppm; pH 7.73, 7.85 and 7.67; DO 3.51, 3.92 and 3.65 ppm; BOD 0.93, 0.73 and 3.15 ppm; hardness 95.00, 108.56 and 105.11 ppm; alkalinity 48.9, 120.7 and 249.1 ppm, and acidity 2.18, 2.67 and 2.05 ppm were investigated from Ramna, Crescent and Hatirjheel lakes, respectively. Lower concentration of DO was observed in all three lakes that severely harmed the aquatic organisms and degrade their habitat. The comparative study demonstrated that the concentration of BOD, EC, TDS, alkalinity and acidity of Hatirjheel Lake was higher than Ramna and Crescent lakes which indicated pollution of the lake water. The rain and storm water runoff, lack of awareness of people were responsible for the pollution of Ramna, Crescent and Hatirjheel lakes water. Connection of the sewerage line with the rain water collection channels and mixing of solid waste with lake water are the main reasons for pollution of Hatirjheel lake. Poor water quality of these lakes affects the ecosystem and aesthetic beauty negatively. To maintain the sound environment and healthy ecosystem of the lakes and the surrounding areas need proper management and monitoring and implementation of existing laws and regulations. Moreover public awareness is necessary otherwise it is hardly possible to maintain sound water quality of these three lakes.J. Environ. Sci. & Natural Resources, 8(1): 1-5 2015

St. Martin is a miniature island in the north-eastern part of the Bay of Bengal, which is distinct from the Cox's Bazar-Teknaf peninsula, Bangladesh. Currentlythere are around 6000 people amidst the majority number of peoples primary livelihood sources are fishing, tourism,and agriculture.However, it has become a great tourists attraction spot in Bangladesh due to its unique landscape. Consequently, its natural environment and ecosystem, especially unique biodiversity is obliterating frequently by-virtue-of indiscriminate human activities. This problem is triggering due to lack of education and awareness. Contrary, application of environmental ethics canminimizefurther damages as-well-as rehabilitatetheisland anew. Lately, the government and some NGOs have already taken and implemented several stepsto protect the island but not fruitful still due to some drawbacks. This study reveals that population control, ecotourism, appropriatezoning system for sustainable development,introducing renewable energy, and spreading education amid mass people can resolve the dispute and resettle. Moreover, involving community people in the management program and initiating cottage industry as substitute of income sourcescan reduce pressure on island natural resources depletion.J. Environ.

Temperature Anomaly and Severe Cyclone Events in the Southern Coastal Regions of Bangladesh
Authors: Farukh MA , Baten MA
Published: August 2015

Bangladesh is a disaster prone country where cyclone occurs more frequently in recent decades. In this study, 52 cyclone events observed mainly in the southern coastal regions of Bangladesh from 1960 to 2010 were considered. Extreme weather data were obtained from Disaster Preparedness Centre, AIT and Bangladesh Bureau of Statistics. NCEPNCAR reanalysis data were used to find out the distribution of temperature anomaly over Bangladesh and Bay of Bengal (BB). Skew-T Log-P analysis is done to assess vertical instability of upper atmosphere. The results suggest the prevalence of severe cyclones like category 3 to 5 is mostly from September to December, which are increasing since last two decades. The Skew-T Log-P analysis derived instability indices like CAPE, CIN, KI, LI, and SHOW are very useful to assess extreme weather phenomena. But the strongest signal behind severe cyclone formation over BB is the formation of relatively cooler zone (strong negative anomaly) near to surface level, whereas at the same time the upper atmosphere was dominated by the development of relatively warmer zone (strong positive anomaly).J.

Published: August 2015

The study was undertaken to examine the extent of women along with men participated in post-harvest activities; to identify the problems and constraints faced by them and find suitable solution from their perception. The post-harvest activities were estimated at farm level in Aman rice at Rangpur, Nilphamari, Khulna, Satkhira and Jessore district of Bangladesh by using survey data collected randomly from 270 rice growing households for the year 2012-13. It employed participatory approaches to investigate farmers perceptions on post-harvest management. The analyses shows women spends more time (591 hours ha-1) on PH activities than men (581 hours ha-1) but the ultimate decision maker of those activities are male indicating that women are very seldom given the opportunities to implement their ideas for execution although they are now gaining the right to give their opinion because of social awareness.J.

Published: August 2015

The study was carried out using seven varieties of jute, two varieties of kenaf and one variety of mesta to evaluate their germination potential to chromium (Cr) toxicity. Percent germination and primary growth parameters of these varieties in Cr contaminated medium were observed. Six levels (0, 20, 40, 80, 120 and 160 mg Cr L-1) of Cr were applied in artificial germinating medium following CRD with three replication. All the jute, kenaf and mesta varieties showed decreasing trend of germination with increasing levels of Cr. Germination of kenaf (HC-95 and HC-3), mesta (Samu-93) and jute (CVE-3 and BJC-7370) were satisfactory levels up to 160 mgCr L-1. The root and shoot lengths and fresh and dry weights also reduced with increased concentrations of Cr as the toxic effect of Cr retards the growth of meristematic tissues of young roots and shoots. Morphological deformities like twisting, curling of leaves and shoot and rottening of roots appeared at high concentrations of Cr. Due to receiving higher concentrations of Cr the color of the roots became dark brown to black. The potentiality of the varieties to Cr toxicity were kenaf HC-95 > kenaf HC-3 > mesta Samu-93 > jute CVE-3 and > jute BJC- 7370. The findings of the present study can be applied for sowing kenaf, mesta and jute seeds in Cr contaminated soil.J. Environ. Sci. & Natural Resources, 8(1): 51-57 2015

Temporal Monitoring of Monsoon Crop Using MODIS 16 Days Composite NDVI Data for Food Security
Authors: Sarker MH , Uddin MH , Ali MS , Akhand MR , Rahman SMM
Published: August 2015

Bangladesh is an agricultural country and rice is our main crop. It has three types namely Aus, Aman and Boro. The area of Aman is (52.46%) higher than that of Boro (36.43%) and remaining are Aus. SPARRSO has been successfully monitored Aman and Boro rice for last two decades. Due to less percentage of Aus rice (Monsoon crop) area and planting time mostly in monsoon period no one has monitored it regularly. But accurate and timely information on Aus growth and their acreages are essential for strengthening countries food security. Conventional methods of collecting this information are relatively costly and time consuming. Contrarily, satellite observation with its unique capability to observe the earth's surface repeatedly over large area offers a potential means for country scale monitoring of crop condition. The optical remote sensing NOAA, Terra/Aqua, SPOT, Landsat images are not so enough for temporal monitoring of Aus rice due to cloud cover in monsoon period. RADARSAT data is very much useful for such purpose but data is not available as it is very expensive. So study of Aus rice monitoring using MODIS, 16-days composite, NDVI images at 250 m resolution may effectively use for such purpose. The study reveals that about 263011 hectare areas have been found in Barisal region under Aus rice cultivation in 2010.J. Environ. Sci. & Natural Resources, 8(1): 147-152 2015

Published: August 2015

An experiment was conducted to evaluate the major seed borne fungal diseases of fruits in Mymensingh. Being perishable crop the fruits were found easily prone to the attack of various disease causing organisms at almost all sphere of their production practices from orchard to the storage, transit and consumption. Fruit rot (Botryodiplodia theobromae) and anthracnose (Colletotrichum gloesporioides) were found as the most common and serious diseases in many fruits such as mango, guava, banana, papaya, pineapple etc. Prevalence of the diseases, losses incurred and probable control measures have been suggested in most of the cases.J.

MULTI-OBJECTIVE TIME-COST OPTIMIZATION USING COBB-DOUGLAS PRODUCTION FUNCTION AND HYBRID GENETIC ALGORITHM
Authors: SHEN Zhigang , HASSANI Ashkan , SHI Qian
Published: August 2015

Existing research on construction time-cost tradeoff issues rarely explore the origin of the crashing cost. Crashing cost function was either assumed without much justification, or came from historical data of some real pro­jects. As a result the conclusions of the papers can hardly be used to guide allocations of labor and equipment resources respectively. The authors believe Cobb-Douglas function provides a much-needed piece to modeling the cost functions in the construction time-cost tradeoff problem during the crashing process. We believe this new perspective fills a gap of existing time-cost tradeoff research by considering project duration, labor and equipment cost as parameters of the Cobb- Douglas production function. A case study was presented to show how the proposed framework works. Our conclusion is that introducing Cobb-Douglas function into time-cost tradeoff problem provides us extra capacity to further identify the optimal allocations of labor and equipment resources during crashing.
THE EFFECT OF ASPECT RATIO AND VOLUME FRACTION ON MECHANICAL PROPERTIES OF STEEL FIBRE-REINFORCED OIL PALM SHELL CONCRETE
Authors: YAP Soon Poh , ALENGARAM U. Johnson , JUMAAT Mohd. Zamin
Published: August 2015

The utilization of oil palm shell (OPS) as a replacement for conventional coarse aggregate produces a greener structural lightweight aggregate concrete (LWAC). Steel fibres enhance the mechanical properties of LWAC including OPS concrete (OPSC). This paper reports on the influence of the aspect ratio (l/d) and volume fraction (Vf) of hooked end steel fibres in oil palm shell fibre-reinforced concrete (OPSFRC). The fresh and hardened concrete properties, including ultrasonic pulse velocity (UPV) and post-failure compressive strength (PFCS) of ten mixes with three each for l/d (55, 65 and 80) and Vf (0.25%, 0.5% and 0.75%) are investigated. The mix with an l/d of 65 produced the highest values of slump, density, and compressive strength. The enhancement in the splitting tensile strength of 83% compared to the control mix was obtained for the mix with the highest l/d. Generally, the increase in Vf from 0.25% to 0.75% improved the mechanical properties. The UPV results indicated that all OPSFRC and PFCS of 66–70% obtained were of good quality.
NUMERICAL STUDIES ON SMOKE SPREAD IN THE CAVITY OF A DOUBLE-SKIN FAÇADE
Authors: JI Jie , LI Yi Fan , SHI Wen Xi , SUN Jin Hua
Published: August 2015

In this paper, influence of two key factors, fire room height and outer pane tilt angle, on smoke spread in the cavity of a double-skin façade (DSF) was studied numerically. The fire room was located adjacent to the DSF on the 2nd, 4th and 6th floors, respectively. The outer pane tilt angle varied at 80°, 90° and 100°. All cases were under two fire heat release rates of 1 MW and 5 MW. Results suggested that fire room height and outer pane tilt angle had significant effects on smoke spread in the cavity. For different fire room heights, there were two markedly different scenarios of smoke spread in the cavity between two vertical panes in a high-rise building. For outer pane tilt angle, the DSF with an inward tilted or vertical outer pane was dangerous for the upper floors due to hot smoke adhering to the upper inner pane. However, the turbulent vortex in the DSF with an outward tilted outer pane prevented hot smoke flowing out from the fire room.

Published: August 2015

Displaced femoral neck fractures in physiologically young patients are best treated with anatomic reduction and stable fixation. Several surgical approaches to the femoral neck have previously been described, although they are fraught with disadvantages such as poor visualization, the need for 2 incisions, and risk of injury to the lateral femoral cutaneous nerve and branches of the medial femoral circumflex artery. The authors’ hybrid anterolateral approach to the hip allows for excellent visualization of femoral neck fractures and for placement of plate and/or screw constructs through a single incision. This surgical technique additionally minimizes risk to neurovascular structures. [

Complications Associated With Arthroscopic Labral Repair Implants: A Case Series
Authors: Felder Jerrod J. , Elliott Michael P. , Mair Scott D.
Published: August 2015

Arthroscopic labral repair in the shoulder has become commonplace in recent years. A variety of implants have evolved in parallel with arthroscopic techniques. Any orthopedic implant that is placed in close proximity to the joint has the potential to cause subsequent damage to the articular surface if it is left prominent or dislodges secondary to improper surgical technique. This article focuses on a series of implant-related complications of labral surgery and their subsequent management. Additionally, correct patient selection and surgical technique are discussed. [

Stemless humeral fixation has become an alternative to traditional total shoulder arthroplasty, but metaphyseal fixation may be compromised by the quality of the trabecular bone that diminishes with age and disease, and augmentation of the fixation may be desirable. The authors hypothesized that a bone graft substitute (BGS) could achieve initial fixation comparable to polymethylmethacrylate (PMMA) bone cement. Fifteen fresh-frozen human male humerii were randomly implanted using a stemless humeral prosthesis, and metaphyseal fixation was augmented with either high-viscosity PMMA bone cement (PMMA group) or a magnesium-based injectable BGS (OsteoCrete; Bone Solutions Inc, Dallas, Texas) (OC group). Both groups were compared with a control group with no augmentation. Initial stiffness, failure load, failure displacement, failure cycle, and total work were compared among groups. The PMMA and OC groups showed markedly higher failure loads, failure displacements, and failure cycles than the control group (
P
<.01). There were no statistically significant differences in initial stiffness, failure load, failure displacement, failure cycle, or total work between the PMMA and OC groups. The biomechanical properties of magnesium-based BGS fixation compared favorably with PMMA bone cement in the fixation of stemless humeral prostheses and may provide sufficient initial fixation for this clinical application. Future work will investigate the long-term remodeling characteristics and bone quality at the prosthetic-bone interface in an in vivo model to evaluate the clinical efficacy of this approach. [

Published: August 2015

En las inmediaciones de Sparanise se ha construido un complejo fabril, constituido por cuatro grupos de industrias diferentes, cuyos edificios ocupan un solar de 850.000 m2, inmediato a la carretera nacional Appia, dotado de todos los servicios, redes de viales, de agua, luz y combustibles, garaje, talleres, oficinas, etc. La empresa iniciadora es la Manufactura Cerámica Pozzi.
Se ha cuidado de que la línea general arquitectónica para los distintos edificios que componen cada grupo sea homogénea, y de que el conjunto tenga un tratamiento semejante que le dé la debida unidad.
Aunque las estructuras son muy similares, pues todas ellas se componen de vigas pretensadas para los forjados de cubierta, aquéllas varían de una a otra nave, en cada grupo, de acuerdo con las luces previstas para las crujías, y, además, la variación se acentúa en el grupo de barnices, cubierto con elementos prefabricados, de sección en forma de V, realizados en un taller, próximo a la obra, dotado de una importante grúa-pórtico para la manipulación, elevación y empilamiento de los elementos terminados, cuyo peso varía de 13 a 14 toneladas.
Una empresa especializada fue encargada de reconocer el terreno y fijar las cargas máximas admisibles sobre el mismo, así como el tipo más adecuado de cimentación en cada caso.
Nave de montaje Volkswagen, Venezuela

Published: August 2015

Para el montaje de los coches Volkswagen destinados al mercado venezolano, se ha construido una gran nave dotada de todos los servicios necesarios: pintura, engrases, aparcamiento de los vehículos terminados, etc.
La elección del lugar más apropiado para la situación de la nave y edificios anexos fue motivo de un detenido estudio, en el que la proximidad a zonas industriales, clima, fácil entrada de materiales procedentes de ultramar y salida para los acabados, fueron los factores decisivos. Definitivamente se eligió un solar en las cercanías de Morón, del departamento de Carabobo, y próximo al mar.
Lo más notable es la cubierta de la gran nave, formada por una serie de láminas parabólico-hiperbólicas de hormigón armado, de planta rectangular, inclinadas ligeramente hacia el norte para formar un perfil en diente de sierra.
Cada una de estas láminas se soporta por un montante central.
Los huecos que dichos dientes de sierra dejan se han aprovechado para la ventilación.
Los cerramientos se han realizado con materiales que forman celosías, consiguiendo así mejorar la ventilación.
