“Laughter in the Dark is a brilliantly composed portrait of Egypt’s answer to hip-hop—and how it functions as a musical genre, economic engine, and cultural force amid the restrictions of an increasingly authoritarian regime. Meticulously reported and elegantly written, it’s a must-read for any global citizen.” –ZACK O’MALLEY GREENBURG, author of Empire State of Mind: How Jay-Z Went From Street Corner to Corner Office
“In Laughter in the Dark, Yasmine El Rashidi provides a brisk, brilliant, and brave portrait of young Egyptians simmering under the weight of President Abdel Fattah El-Sisi’s repressive dictatorship and reveals the stark inequality between the rulers and the ruled.” –BASHARAT PEER, author of A Question of Order: India, Turkey, and the Return of Strongme
The theories behind human responses in coloured environments
No full textThis chapter aimed to describe and discuss the theories that explain some aspects of nature and the research into the effects of a coloured environment on humans. The theories were proposed from various but related domains in previous studies, ranging from existing colour theories, psychology, human biology, learning, ecology and performance perspectives. The discussion highlighted some findings, research gaps, and arguments for a clearer understanding of the applications and to highlight their significance. Research with the preparation of a theoretical framework from its early stage, covering a multitude of perspectives, could facilitate an exchange of ideas across domains and develop creative and possible outcomes to enhance knowledge of the built environment. © 2025 Nova Science Publishers, Inc
Evaluation of mangrove species as phytoindicator for brackish water contamination / Mohd Idwan Idris, Rashidi Othman and Izawati Tukiman
Get PDFMangroves ecosystem has become a resource that plays a significant role in maintaining the ecological value
and human settlement need. In the sense of environmental impact, mangroves currently happened to be widely
exposed to elevated heavy metal loads. Heavy metal enrichments are contributed by a variety of ongoing
activities such as urban development, industrial, agricultural, and shipping activities. The aim of this study is to assess three different mangrove species as phytoindicator for three types of heavy metals contaminants in brackish water bodies at 2 different localities. All of the water samples were analyzed for lead (Pb), chromium (Cr), and zinc (Zn contaminations. The results show that 3 mangrove species which are Avicennia alba, 6ypha fruticans, and Rhizophora apiculata were found effective in indicating heavy metals contaminant in that
particular environment. Based on the concentrations of heavy metals in brackish water, mangrove species can be
relevant indicators for the state of a mangrove area in terms of quality of environment
Assessment of aquatic ecosystem status using macrophyte species as key tools indicator for heavy metal pollution
No full textAquatic plants or macrophytes are beneficial to fresh water bodies because they produce oxygen, which assists with overall fresh water bodies functioning, and provide food and shelter for aquatic living organisms. A lack of aquatic plants in a freshwater bodies system where they are expected to occur may suggest a reduced population of macro and micro fauna. In addition, the absence of macrophytes may also indicate water quality problems as a result of excessive turbidity, herbicides, or salinization. However, an over abundance of macrophytes can result from high nutrient levels and may interfere with freshwater bodies processing, recreational activities and detract from the aesthetic appeal of the system. In this study, sixteen water samples were collected from four different places (Selangor, Perak, Pahang and Kelantan) where six different macrophytes species were abundance and dominant. All the water samples were analyzed by using Atomic absorption spectroscopy (AAS) for six types of heavy metals which are iron (Fe), lead (Pb), copper (Cu), zinc (Zn), nickel (Ni) and manganese (Mn). All six different macrophytes species which are Eichhorniacrassipes, Hydrillaverticillata, Cabombafuscata, Salvinianatans, Nelumbonuciferaand Pistiastratiotesexhibiting highly significant differences (P< 0.0001) between aquatic plant species widespread, locations and the heavy metals content. This clearly demonstrates that freshwater environment with abundance of invasive macrophyte species can have an important influence and indication on the accumulation of heavy metals content. The importance of the interaction components emphasises that the changes in heavy metals composition are complex and the responses are not consistent across all aquatic plant species. Examination of the summarised data revealed that, of the 6 macrophyte species analysed at all different locations, all exhibits as potential ecological indicator for unhealthy aquatic ecosystems or as phytoindicator for heavy metal contaminants either at low or high level contamination. Therefore, macrophyte is an effective tool in responding heavy metal in low level environmental contamination that might otherwise be difficult to detect
Ecological indicator agents for inorganic contaminants state monitoring through Sonneratia Alba, Avicennia Alba and Rhizophora Apiculata
No full textMangrove forest ecosystems are threatened by direct impacts such as cutting and pollution due to agricultural, industrialization and urbanization activities. Mangrove forests are often regarded as unpleasant environments with little intrinsic value. Mangrove forests perform valued regional and site-specific functions. Mangrove species can take up excessive nutrients and also play a crucial role in creating a favourable environment for a variety of chemical, biological and physical processes that contribute to the inorganic removal and degradation of organic compounds. Among the many mangrove species, Sonneratia alba, Avicennia alba and Rhizophora apiculata have been studied for biomonitoring of toxic heavy metals elements (Fe, Cu, Zn, Pb and Mn) in a wide range of plant tissues (roots and leaves) and sediment composition at three different locations in Negeri Sembilan, west coast of Malaysia. The results established that there were significant differences between the three mangrove species, locations, plant tissues and sediment samples and their interaction for all the five heavy metals content. The findings revealed that leaf tissues for all species accumulated mostly Fe, Zn, Pb and Cu. Interestingly we noticed that different localities will accumulate different type of heavy metals, for instance R. apiculata leaf tissues were detected with higher concentration of Cu and Pb at Kampung Sungai Sekawang whereas in another two sites were detected with Cu, Fe, Zn and Pb. S. alba indicated that the most heavy metals highly accumulated was Zn followed by Pb and Cu at Pasir Panjang. In this study A. alba showed Zn was highly accumulated in leaf tissues at Pasir Panjang. Thus, those three mangrove species appear to have the greatest potential for use as an effective ecological indicator tools as green application for inorganic contaminants monitoring in mangrove ecosystems
Landscape ethnobotanical study of Malay midwifery plant species: case study of Kelantan
No full textTraditional Malay midwifery practices in Kelantan exhibit a wide variation in plant materials selection. This study
established that plant materials composition selection differs greatly with respect to stage of midwifery practices,
locality, environmental factors and culture. A total of 6 types of Malay midwifery practices using plants were
observed in 5 different localities in Kelantan. Lenggang perut practice was performed during prenatal treatment
whereas another five practices (bertangas, bertungku, berparam, berpilis and mandi serom) were performed during
postnatal treatment. In relation of creating Malay garden identity, the findings established that the most influential
factor appeared to be stage of Malay midwifery practices. Each practice has specific purposes and functions which
later determine the accumulation of plant materials selection. Of all the Malay midwifery practices studied in this
research we found that mandi serom is the most diverse plant species used which portray the habitat or type of
environments in which these plant species origins or found. There may be similarities of some species due to
similar knowledge, culture or environmenthowever, the magnitude of these effects is not as great as plant
materials composition selection and usage. By identifying the key factors controlling plant materials selection and
usage a greater understanding of how certain midwifery practices influence plant species selection and
composition in response to interactions with environmental factors as well as culture, belief and taboos will
emerge as potential softscape elements tools and indicator in creating identity of Malay landscape for specific
culture and locality
