Many existing steel structures are now considered to have a rising number of structural deficiencies, therefore, studying strengthening techniques of these structures is an essential task. Several successful studies have been conducted to retrofit steel beams using carbon fiber-reinforced polymer (CFRP) strips. Numerous previous studies have focused on CFRP strengthening of steel beams with flat web, but similar studies on corrugated web steel beams (CWSBs) are scarce. The present study aims to investigate numerically the effectiveness and feasibility of applying CFRP shear strengthening technique for CWSBs. A nonlinear finite element (FE) analysis is employed to construct a numerical model to simulate CFRP strengthened CWSBs, taking into consideration the contact between surfaces. The accuracy of the generated FE models has been verified with the available experimental results from previous studies. A parametric study is conducted on eighteen specimens divided into two groups (Local and global buckling groups) according to web slenderness ratio which is related to the expected buckling mode. The study takes into consideration different CFRP strips schemes (bonded on flat folds only or both flat and inclined folds), arrangement (bonded on one-fold side or both-fold sides) and length of CFRP in the cross-section directions. The results concluded that the proposed CFRP strengthening system increase the shear strength of CWSBs by considerable magnitude up to 49.17% with noticeable reduction of web deformations.

The green infrastructure development to manage rainwater excess on the surface of the ground can be performed by using various methods including collecting rainwater for immediate use, or in artificial reservoirs and then absorbed into the ground. This is the implementation of the concept of rain harvesting, and Low Impact Development (LID). Using the environmentally friendly concept is expected that rainwater can be stored, utilized, and added to the potential sources of ground water. This study analyzed the engineering of green infrastructure which consisted of mapping several aspects: LID and rainwater harvesting. This study also discussed about the use of the layout of Sekaran campus at Universitas Negeri Semarang (UNNES) in developing the Green Campus. The results of the analysis showed that area of rainwater catchment in the form of the roof surface = 76686.42 m2, 108 bio pore holes, 1 water reservoir and 4 infiltration gardens. The number of areas that have not yet been built (unbuilt up area) which is subsequently converted to a built-up area and potential as an impermeable region is 99903, 19 m2. The impact of campus infrastructure development causes a reduction in green open space. The solution to the above problems is that UNNES can implement the green infrastructure concept at the Sekaran Campus, (UNNES) by meeting the zero delta Q requirements as an effort to support the implementation of a green campus. One of the efforts is to make 69 to 133 infiltration wells located in the area of UNNES.

Recycling of materials can play an important role in sustainable environment and in the development of economy. In accordance with this generalized sustainable practice, the feasibility study of using non-metallic fractions (NMFs) from waste liquid crystal displays (LCDs) with waste polyethylene terephthalate (PET) bottles to produce a valuable composite material was carried out. Different composition of LCD-PET composite material was investigated in terms of mechanical strength properties and examination of composite fracture surfaces. The acquired results showed that the mechanical properties such as tensile strength, bending strength, impact strength and modulus of LCD-PET composites is improved by increasing of NMFs of LCDs. The optimum results of mechanical strength properties reflected in morphologies of fractured surface was obtained at 70 %wt of NMFs. At optimized weight ratio of NMFs in LCD-PET composite samples, tensile strength (0.46 MPa), tensile modulus (0.35 MPa), bending strength (2.09 MPa), bending modulus (14.15 MPa) and impact energy (0.74 J) was achieved. The improved value of these properties are due to strong adhesion bonding between particles of NMF and PET. This research suggests that the utilization of NMFs of waste LCDs with PET will result in the substantial reduction of environmental pollution.

The aim of this work is to study the climate variations on a global scale by providing new radiometric data from the travertine of Erfoud’s Radier. This travertine is formed of two units, lower and upper, separated by a discontinuity surface. Our U/Th dating allowed to position the lower unit between 262 ka and 177 ka, which is contemporary with isotopic stages 8 and 6. As for the upper unit, it is between 30 ka and 11 ka, contemporary with isotopic stage 2. The even isotopic stages indicate that the climate was cold in Europe at that time while it was hot and humid in Morocco, favoring the formation of this travertine. From the obtained data, this study can rely on the climatic correspondence hypothesis described by Petit-Maire for the last two climatic extremes (18000 ± 2000 and 8000 ± 1000 ka) in the world, could be extended for a long time.

The electricity supply of Rwanda is composed of domestic generation and the imported electricity from neighboring countries and regional shared power plants. The sources of energy used are from hydropower plants, thermal power plants (Diesel and Heavy fuel generators), methane gas and solar energy. Rwanda possesses significant renewable energy resources and the government aims to utilize these in order to reach its target of increasing total generation capacities and 100% of households should be connected by 2024. Renewable energy technologies are available from different natural resources such as biomass, geothermal, hydropower, and Solar (photovoltaic and solar thermal). In this paper, the authors analyzed the development of the most renewable energy sources and technologies. The result shows that renewable energy resources appear to be one of the most efficient and effective solutions for clean and sustainable energy development in Rwanda and geographical location has shown the advantages for developing the use of most renewable energy sources. Rwanda’s energy and electricity supply are dominated by hydropower, solar, biomass and thermal, but the environmental impacts and cost of each technology have to be taken into considerations. The authors recommend the government to promote the use of small/mini-grids in power generation in both rural and urban areas and also to allocate necessary resources to maintain and sustain the renewable energy technologies.

Phycology is systematic study of macro algae and key discipline to important analysis. Seaweeds are the macroscopic, multicellular algae which are important as primary producers in the ocean. In addition, they have great economical and medicinal importance and also provide shelter and nursery ground for the marine organisms. Records on seaweed research, in Eastern province in Sri Lanka is scares. Hence, the present study was focused on preliminary survey of seaweed species abundance, frequency, cover percentage and the anthropogenic activities that thread their sustainable live span were conducted at Vandalous bay of Sri Lanka in Indian Ocean in order to find out the possible threats. Twenty sampling points were selected including of various micro habitats (coral, rock and sea grass) in Vandalous bay during low tide were used to assess the diversity and distribution of seaweeds quantitatively during the period from January to May 2018. Further, physio-chemical water quality parameters were also measured at the study site such as temperature, dissolved oxygen, turbidity, pH and salinity. Line-transect with intercept quadrate method was used to assess the distribution in upper intertidal zone ranging up to 20 m to collect the seaweed samples on monthly basis. Collected samples were identified using standard seaweeds taxonomic key. The present study revealed 40 species belonging to 27 genera, 20 families, 12 orders and 3 classes out of which 55% were green algae, while red algae and brown algae were recorded as 26% and19% respectively. High abundant species was Halimeda opuntia found in almost all the sampled points in study site, it was large scale (ranging from 1.9-3.9) and restricted to coral region and few of them found in seagrass. The less abundant species was Galaxaura rugose (ranging from 1.2-2.1) and other species were moderately distributed in study site. Further, Halimeda opuntia and Carpopeltis maillardii were highest and lowest frequency ranging respectively at the study side. The former registered from 50% to 100% and the later registered 10%. The identified anthropogenic activities were hotel waste discharge, fishing and tourism. In those activities, fishing was the most dominant while hotel waste elimination and tourism had less influence on seaweeds bed. Cladophoraceae was the most diverse family represented by 5 species. Among the study species, green algae were dominant in which Halimeda opuntia was highly abounded and restricted to coral micro habitats. However, red algae share rocky substrates in addition to the coral micro habitats. Sphacelaria novae-hollandiae (brown alga) which was recorded as a new species in Sri Lanka was also collected in the present study site. Hotel waste discharges and the tourism soon after cessation of civil unrest were identified as major threats. Further, future studies must be directed for long term investigation on seasonality, factor controlling existence and distribution of seaweeds along the Vandalous Bay in East coast.

This study investigated the effects of social media to the academic performance and well-being of Grade 10 students in Central Mindanao University Laboratory High School. The study aimed to know the advantages and disadvantages of using social media and on how and why does it affect the students’ and academic performance and well-being. Explanatory case study design was utilized in the study. A questionnaire adapted from Portsmouth University and a semi-structured interview protocol was used for collecting data. Participants are purposively selected based on their exposure to social media, academic performance, and well-being. Qualitative analysis indicated that the use of social media is of advantage to students because it enhances communication, gives information, offers entertainment, and provides safety. However, it is disadvantageous since it stimulates isolation/lack of physical interaction, increases probability of misdeeds, decreases motivation and focus, contains toxic side, and may spread misinformation. Social media affects students’ academic performance and well-being in many ways. It can decrease attention span, promote health deterioration, expand explanations on lessons, heighten stress, enhance proper communication and seeking assistance, encourage motivation and independence and trigger relationship and personal issues. These effects can be attributed to too much information and tasks, household responsibilities, lack of sleep, more screen time, lack of physical activities due to staying at home, access to unlimited information, procrastination, difficulties in learning, access to different media platforms, flexible schedule and more time in social media.
