Energy efficiency in buildings is today a prime objective for energy policy at national and international levels. Because the residential and commercial energy consumption has steadily increased reaching figures between 20% and 40%. The use of thermal insulation of the building envelope is one of the most currently requested solutions to reduce this energy consumption. Phase Change Materials (PCM) have received increased attention due to their ability to store large amounts of thermal energy within narrow temperature ranges. This property makes them ideal for storage of passive heat in the building envelopes. An experimental study was conducted to analyze the influence of PCM in the construction of exterior walls. Two test cells are constructed in the Faculty of Science Ain Chock, Casablanca. One is equipped with a 0.56 cm layer of PCM on its roof while the second is a reference cell without PCM. The results presented for the period from 8th to 10th July 2014 show that the integration of PCM layer reduces the amplitude of instantaneous heat flux through the horizontal wall. The indoor and the internal vertical wall temperatures, in the case of the cell with PCM, are relatively decreased compared to those of the reference one. For example, the maximum deviation between the indoor temperatures of the cubicles is not more than 1.5℃ while the one on the west faces reaches 3℃ by mid day. Also the inclusion of a layer of PCM shifts the time of peak load and discharge.

Mangroves are salt-tolerable trees that grow on zones parallel to the coastline along the creeks. They follow the mud flat accretions which are unvegetated areas consisting of sand or gravel that are either exposed or flooded by tides. They provide 70% of the wood requirement along the Kenyan Coast. Currently, there are no harvest plans of the mangroves and there is selective removal of suitable poles and most of the quality poles have been wiped out. This not only leaves the inferior species unsuitable for the market but also affects the quality of the forest. Moreover, areas that are suitable for mangroves growth have been occupied by human settlement and infrastructure, hence, there is a need of sustainable use of the mangroves so as to protect them from degradating and eventually extinction. To achieve this, geospatial techniques need to be employed in order to determine the spatial extent of the vegetation and devise methods and plans of managing them. The Kilifi Mangrove Forest creek is home to major six species: Avicennia marina, Ceriops tagal, Sonneratia alba J., Rhizophora mucronata, Lumnitzera racemosa and Bruguiera gymnorrhiza. This study showed that the most dominant species in the forest is Avicenna Marina which had a percentage stand of 25.6%. The less dominant species Lumnitzera racemosa and Heritiera littoralis had a stand of 0.10% which were restricted for harvesting in the analysis, they need to be protected so as to prevent its extinction in the forest which will affect the biodiversity and richness of the forest. Density and heights of the mangroves were considered so as to decide on which areas to do reforestation in order to protect the forest and help in preventing soil erosion. The final suitable area for harvesting after carrying out conditional and majority filter was 394 acres which are 9% of the total forest area. The total area most suitable for reforestation is 1151 acres which are 27% of the total Kilifi Mangrove Forest. A recommendati

The Atlas cedar (Cedrus atlantica) is one of the more valuable reforestation species in the Mediterranean areas. But this species suffers from rainfall limitation and climate changes, particularly in its originated area, North Africa. Therefore, any knowledge about the plantation practices to improve the tree water availability and the reforestation success has great importance. The current study has been undertaken in this view, i.e. to compare the growth of cedar plots located in El M’Sid Mountains, Souk Ahras department (700 km east of Algiers), according to different planting methods. The radial growth and the productivity have been measured on a cedar plot with a total surface of 165 ha. 150 ha has been planted in 1970 on hillside ditches, and 15 ha of which the majority is planted in a simple hole and some bouquets on terraces, both are originated from a complementary reforestation achieved during 1980. The results show that most of the trees planted in 1970 reach a height ranging between 10 and 17 m and a diameter between 23 and 44 cm. Even some trees were 20 m high with diameter of 65 cm. The productivity fluctuates between 3 and 8 m3/ha/year, values close to the one of natural native plots. Trees planted in 1980 reach a height ranging between 5. 5 to 7 m, and diameter between 11.5 to 23 cm. The radial growth improves that the hillside ditches help the roots anchoring and trees growth during the first season after plantation. These results indicate that the cedar tree can be used with success in areas outside the natural cedar forest presence, and that appropriate planting techniques can compensate in part the lower rainfall occurring in these chosen regeneration areas.

稀土掺杂上转换纳米材料因其具有优异的光学性能而被广泛应用于生物医学成像﹑临床治疗﹑太阳能电池等领域,已成为国内外材料科学与化学领域的研究热点之一。其中,核壳结构上转换纳米材料展现出更为优异的光学性能,可以通过对晶核进行惰性壳层、活性壳层及多种功能性壳层的包覆,从而赋予上转换荧光纳米材料更为广泛的应用性能。掺杂镧系元素的上转换纳米粒子(UCNPs),尤其是808nm激活的UCNPs,由于其具有最小的组织过热效应和低自发荧光背景,是用于生物学应用的有前途的成像剂。为了增强上转换发光,本文构建了新型Nd敏化的核-多壳结构纳米颗粒。本文选择NaYF作为基质,采用热分解法合成该核壳结构纳米颗粒。在晶核中控制Nd掺杂离子浓度,对其形貌、尺寸和荧光性能进行了测试,确定最佳的晶核结构和Nd掺杂浓度。其次,第二层中选用Yb和Er作为敏化剂和活化剂,并对离子掺杂浓度进行了优化。最后优化了第三层的离子掺杂浓度,确定最外层Nd掺杂浓度为30%,从而制备了Nd敏化的核-多壳NaYF:Yb/Nd@NaLuF:Yb/Er@NaYF:Nd的上转换纳米粒子。接下来采用表面活性剂CTAB和正硅酸乙酯TEOS对该种核壳结构上转换纳米晶进行了多孔SiO包覆,通过合成条件优化可以实现多孔SiO在NaYF:10%Nd@NaLuF:20%Yb:2%Er@NaYF:30%Nd上转换纳米晶表面的均匀包覆,并对其上转换荧光性能进行研究。此外,对制备的多孔SiO包覆的上转换纳米晶进行了Ce6药物负载的研究,同时对其药物载释过程进行了研究。对于上转换发光,本文证明了包覆壳层可以增加强度。因此,本文控制核心和最外层壳层保持相同的基质材料,但其中的离子掺杂浓度不同。对于生物医学应用,最近的工作证明800nm激发下的纳米颗粒比980nm激发的纳米颗粒具有更多优势。本文讨论的上转换纳米粒子的合成及其在800nm激发下的性质。

A series of 4-thioflavonols compounds were synthesized by treating flavonols with lawsons reagent with variable substituent groups at A, B, and AB rings. All the synthesized compounds were checked for antibacterial and antifungal activity. We report that many compounds were found active against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus, bacterial strains and, C. albicans, C. parapsilosisstrains and C. krusei fungal strains. Most of the synthesized 4-thioflavonols compounds were found to show enhanced antimicrobial activity than respective flavonol compounds.
