Opis:
This research proposed an integrated eco-system for conditioning an outdoor public area (park or sport) in a hothumid environment. It is accomplished by the use of a dehumidifier control machine driven by renewable solar power; after which air is distributed throughout a ducting system. The system will harvest moisture from the air, utilize it for drinking water production and plants irrigation as well as deliver low temperature, low humidity ratio air for controlling the outdoor air, which results in a comfortable outdoor relative humidity and temperature (24 °C, 50% RH). The Integrated Eco-Friendly Cooling System (IEFCS) is a sustainable self-dependent in energy and water sources. It provides a positive impact on the microclimate of the site, assists in night illumination, supplies water for drinking, plant irrigation, and allows people to enjoy a thermally comfortable atmosphere. The advantages include low maintaining cost as well as the possibility to be scaled and implemented anywhere according to the selected location.

Opis:
Obeche (Triplochiton scleroxylon K. Schum.) is a large tropical tree, the wood products of which are either in solid or reconstituted forms. These items are extremely vulnerable to concomitant insect attack. Although established as a successful plantation species for veneering and plywood production, Obeche is also considered as a good environmental tree in Nigeria. However, there is very little specific information that substantiates this potential. We report on the organisms inducing biodeterioration of Obeche wood products and describe the characteristics of Obeche trees in terms of environmental suitability between 2012 and 2016. All the 47 Obeche wood-based products (OWBPs) studied, comprising 12 beehives, 10 food canteen stalls, 10 office tables, 10 laboratory cabinets and 5 office walls were economically and dominantly co-infested by beetles and termites. Interestingly, during the four-year observation period, all the eight Obeche trees encountered were found to exhibit high stability with excellent resistance to hollowness and to degradative pests, even at around 2 m Diameter at Breast Height (DBH). This reflects its robust biophysical protective barrier mechanisms. Additionally, there were observations of enhanced coexistence with other tree species, including shrubs and grasses. This indicates a tolerance potential role at improving the relative contributions of several species (plants community) to ameliorate tropical environmental degradation.

Opis:
In dinosaurs and other archosaurs, the presence of foramina connected with internal chambers in axial and appendicular bones is regarded as a robust indicator of postcranial skeletal pneumaticity (PSP). Here we analyze PSP and its paleobiological implications in rebbachisaurid diplodocoid sauropod dinosaurs based primarily on the dorsal vertebrae of Katepensaurus goicoecheai, a rebbachisaurid from the Cenomanian–Turonian (Upper Cretaceous) Bajo Barreal Formation of Patagonia, Argentina. We document a complex of interconnected pneumatic foramina and internal chambers within the dorsal vertebral transverse processes of Katepensaurus. Collectively, these structures constitute a form of PSP that has not previously been observed in sauropods, though it is closely comparable to morphologies seen in selected birds and non-avian theropods. Parts of the skeletons of Katepensaurus and other rebbachisaurid taxa such as Amazonsaurus maranhensis and Tataouinea hannibalis exhibit an elevated degree of pneumaticity relative to the conditions in many other sauropods. We interpret this extensive PSP as an adaptation for lowering the density of the skeleton, and tentatively propose that this reduced skeletal density may also have decreased the muscle energy required to move the body and the heat generated in so doing. Given that several rebbachisaurids inhabited tropical to subtropical paleolatitudes during the extreme warmth of the mid-Cretaceous, increased PSP may have better enabled these sauropods to cope with extraordinarily high temperatures. Extensive skeletal pneumaticity may have been an important innovation in Rebbachisauridae, and perhaps also in saltasaurine titanosaurs, which evolved an even greater degree of PSP. This may in turn have contributed to the evolutionary success of rebbachisaurids, which were the only diplodocoids to survive into the Late Cretaceous.

Opis:
In recent years, the several causative factors of tree decline have caught our attention in the over 40-year-old University of Port Harcourt (UNIPORT). Identical tree species decline and causing factors increasingly became persistently epidemic on environmental trees across Niger Delta. Despite the global growing demands on tree landscape systems and new concepts of biosecurity needs, which today expect greater responsibility from different societal groups to align these demands with operational utilization of suitable trees hopefully native species, Nigeria still hugely rely on exotic species for its landscape systems. While a plethora of articles have been aired and documented on Niger Delta contemporary issues in local and international debate convergences, the Oil Exploration and Human Developmental Projects (OEHDPs) effects dominate. This study provided utilization based information on Stress-Pests Infestations (SPIs) factors and challenges related to alien ornamental trees in Niger Delta where anaerobic soil condition perennially exists. Soil moisture stress has been recognized as formidable major threat to the safety of exotic (alien or non native species) trees and predisposing susceptible ornamental tree species to fungi invasions and subsequent infestation of living trees by termites, beetles and of recent weaver birds. To reduce the SPIs effectively, and improve human inhabitations, this study stresses the urgent policy need for a paradigm shift from landscape design utilizing alien tree species to the massive use of indigenous trees species native to Niger Delta region.

Opis:
The study aimed to examine the influence of body composition and menopause characteristics on certain temporal parameters of the behavior of vertical and anteroposterior components of ground reactive forces, as well as the vertical and anteroposterior rates on the walking of postmenopausal women. The sample consisted of 67 postmenopausal women, average age 59 years. Body composition was assessed by octapolar bioimpedance and ground reactive force by the Kistler force platform. Vertical loading rate correlated positively with age (r = 0.02) and negatively with weight (r = –0.33). The relationship between the rates of vertical loading and unloading associated positively with menopause time (r = 0.27) but negatively with weight (r = –0.27). Vertical unloading rate showed a negative association with abdominal visceral adiposity (r = –0.27). The relationship between the times of the intermediate and final phases of the support correlated significantly with abdominal visceral adiposity (r = 0.25) and fat mass (r = 0.24). The study suggests that fat mass and abdominal visceral adiposity affect the support time, and increased abdominal visceral adiposity implies a slower pre-suspension phase during the walking of postmenopausal women. Hormone replacement therapy was shown to be an enhancer of steeper vertical loading and anteroposterior unloading and longer time in the double support phase, indicating a greater stability of postmenopausal women when walking.

Opis:
Thermal analysis of a heat and power plant with a high temperature gas cooled nuclear reactor is presented. The main aim of the considered system is to supply a technological process with the heat at suitably high temperature level. The considered unit is also used to produce electricity. The high temperature helium cooled nuclear reactor is the primary heat source in the system, which consists of: the reactor cooling cycle, the steam cycle and the gas heat pump cycle. Helium used as a carrier in the first cycle (classic Brayton cycle), which includes the reactor, delivers heat in a steam generator to produce superheated steam with required parameters of the intermediate cycle. The intermediate cycle is provided to transport energy from the reactor installation to the process installation requiring a high temperature heat. The distance between reactor and the process installation is assumed short and negligable, or alternatively equal to 1 km in the analysis. The system is also equipped with a high temperature argon heat pump to obtain the temperature level of a heat carrier required by a high temperature process. Thus, the steam of the intermediate cycle supplies a lower heat exchanger of the heat pump, a process heat exchanger at the medium temperature level and a classical steam turbine system (Rankine cycle). The main purpose of the research was to evaluate the effectiveness of the system considered and to assess whether such a three cycle cogeneration system is reasonable. Multivariant calculations have been carried out employing the developed mathematical model. The results have been presented in a form of the energy efficiency and exergy efficiency of the system as a function of the temperature drop in the high temperature process heat exchanger and the reactor pressure.

Opis:
The effect of pregnancy on bone metabolism was investigated in healthy mares. Venous blood samples were collected 7 times from 19 multiparous mares starting at 20-weeks pre-parturition, continuing 6 times in 4-week intervals, including the week of parturition and one week after parturition. Serum concentrations of osteocalcin (OC) and carboxy-terminal cross-linking telopeptide of type I collagen (CTX-I) were determined. Measurement cycles and age had a significant (p < 0.01) influence on OC and CTX-I values. Pregnancy influenced bone metabolism with peak bone formation and resorption values around the time of parturition.

Paradoksem Amours jest fakt, że nie były one wyznaniem uczuć do konkretnej kobiety, ale literackim ćwiczeniem. To sam Ronsard, jak mitologiczny Narcyz, studiuje w sobie przeżycia określane jako miłość, obrazy „kochanek" zarysowują się tylko jak cienie. Te cienie są przecież cieniami kobiet i wbrew przypuszczeniom mówią niemało o kobiecie Renesansu.
