Considering sustainability as issue which means creating or maintaining changes in a balanced structure. Concrete is considered as the main constituent of the building industry and its main component is cement but cement releases almost 5 % of Co2 of the world wide emission. To use sustainability as the prominent resources in order to conserve future generation and to find the alternative materials of cement as it emits more Co2 while production. Cement can be replaced by many materials like fly ash, slag, silica fume, metakaolin, egg shell powder, rice husk ash etc. Cements alternative materials such as by-products are been researched upon.

Cement is the main constituent ingredient in concrete. Now days many investigations undergone for substitute of cement due to green houses effect and global warming  .Many new products like rice husk ash, egg shell powder, baggage ash, etc are used as an effluent replacement material for cement. The new and Practical material for substitute of cement is water hyacinth ash .Water hyacinth ash (WHA), is used as an effectual replacement of partial cement, and it has been proved in several characteristics of concrete. The main important parameters in concrete are strength, durability and workability. In this paper, 10 % of cement replaced by water hyacinth ash   to investigate the effects of WHA on  durability and Strength  in concretes. On this basis, specimens were engrossed in water and acid to study the absorption property, acid attack and compared to conventional concrete. The test results show that replacement of cement by WHA in concrete has improved the parameters of concrete.

The most important material which is used for the construction of any concrete structure is concrete itself. It is considered to be as a versatile construction material as its properties can be changed by various means, with the help of different elements and as and when required. Rheodynamic Concrete or Self-Compacting Concrete is a special form of concrete which can easily flow into any kind of formwork uniformly, without facing the problem of bleeding and segregation, gives a better finish, has a great characteristic of placement, requires no vibration, and thus gives a safe working environment. Due to a number of merits, this type of concrete had becoming popular in the construction work. Simultaneously, the big industries across the world are producing the by products such as fly ash, rice husk ash, etc. Thus, this paper represents a review, which is done to incorporate these wastes by – products in Self-Compacting Concrete and observe, how the different properties of the same has been modified effectively and efficiently.

The building industry is blamed for consuming enormous natural resources and creating massive solid waste worldwide. In response to this, the concept of circular economy (CE) has gained much attention in the sector in recent years. Many pilot building projects that implemented CE concepts started to appear around the world, including Taiwan. However, compared with the pilot projects in the Netherlands, which are regarded as the pioneer ones by international society, many CE-related practices are not implemented in pilot cases in Taiwan. To assist future project stakeholders to recognize what the key CE-related practices are and how they could be implemented in their building projects in Taiwan, this study has conducted a series of case studies of Dutch and Taiwanese pilot projects and semi-structured interviews with key project stakeholders of Taiwanese pilot projects. Thirty key CE-related practices are identified via case studies, along with their related 5R principles (Rethink, Reduce, Reuse, Repair, Recycle) and project phases. Suggestion on CE-related practices, their 5R principles, project items, and phases to implement in building projects in Taiwan is also proposed while discussion on differences between two countries’ pilot projects is presented.

This study used social network analysis, which is often adopted to analyze changes in trade structures and the world trade network for faux fur products, which are alternative materials used in vegan fashion. The data on the total trade value of artificial fur (HS Code: 4304) and animal fur and leather (HS Code: 0505) imports and exports between countries were collected through UN Comtrade, and the degree and betweenness centralities were used to analyze the trade structure of faux fur in 2009, 2014, and 2019 using NodeXL 1.0.1 programs. The results of the study are as follows: First, while the total amount of export and import of faux fur is increasing globally every day, the total amount of export and import in other Asian countries and Vietnam is decreasing. Second, due to the reduction in exports of the main producing countries of animal materials such as China, global imports of animal fur and leather decreased. Third, China was the largest ex-porter of faux fur, exporting to a large number of countries; it also played an important role in the intermediation and control over faux fur export. In exporting faux fur, the influence of other Asian countries declined over time, and Vietnam and the United States played an outstanding role as arbitrators in the export network. Fourth, Italy and France were the largest importers of faux fur from various countries and exerted significant influence as intermediaries in the import network of faux fur. On the other hand, Vietnam’s influence in import network decreased. Saudi Arabia appeared to be an important arbitrator in mediating the import. This study is significant due to its findings, obtained through micro-trading data, in respect of industrial moves of ethical fashion in the form of increased trade in faux fur and decline in the trade of animal fur and leather.

This study consists in looking for an improvement of Archachatina margina reproductions performances by amendment of the breeding substrates. As a result, five types of substrate were prepared by soil amendment at different rates (0%, 10%, 20%, 30% et 40%) with chicken egg shell powder. On these substrates, snails were raised from spat stage until they were laid. Reproductive parameters such as: age of first laying, the number of annual laying per animal, the number of eggs per laying on the different substrates were recorded. Overall, snail laying performances improved with increasing rate of substrate amendment. However, beyond a rate of 20%, the weight of eggs laid began to decline. The chicken egg shell powder is suitable for the amendment of the breeding substrate of snails Archachatina marginata in view of an improvement in their reproductive performance. The rate of amendment recommended to this effect is 20%.

<em>Today information resources in Arabic Language are very much useful to the researchers and community of the world. Resources in Arabic language in Kerala, is scattered in various places like libraries attached to Islamic Institutions, kuthb khanas, madrassas, masjids, personal libraries of scholars, and Arabic Colleges. It includes manuscripts, copper plates and digital resources. It should be bibliographically controlled, digitized and preserved for the benefit of future generation. Most of them are concentrated in Malappuram District where muslims are more populated. ALT and ICT will help us to complete this tedious task. It will open a new window to the wide area of information studies and research. The work will be a great help to research scholars, students at various levels, faculties of Arabic departments, academicians and the community as a whole.</em>

Development and civilization have been top-rated priorities and indication of human success in the world; and the largest segment of world talent are immersing to mark new and ever un-experimented record in this course. But paying more attention towards money centric gain and material prosperity centric civilization, an irrational attack on environment is rife everywhere. In last few decades, the environmental strength of world has been largely damaged and it has offered severe impacts on human health now. Though, people were more over-swayed with anthropomorphic use of environment and some transitory progress gained, slowly the imbalance of environment and its reverse effects on human lives have started taking limelight of people. And now, environment seems to be equally pressing and compelling agendas of human checklist to do. If not initiated anything great, it may be more than late to save us and future generation. Thus, the article tries to disclose the impacts of environmental degradation and urges to have efficient actions to alleviate the situation with acknowledging and accessing few of initiatives taken, here so forth.
