Stonehenge, located eight miles north of Salisbury in Wiltshire, England, is a World Heritage Site consisting of megaliths. It was constructed in three stages between 3100 BC and 1550 BC and was in use until the Bronze Age.
Stonehenge is a prehistoric World Heritage Site in Wiltshire, England consisting of a stone circle built in three phases between 3100 BC and 1950 BC. The first phase included a timber circle around 3000 BC, later replaced with stones around 2600 BC. Around 2400 BC, 30 huge sarsen stones were erected forming an inner and outer stone circle, with the remaining bluestones placed innermost. Though its purpose remains unknown, it is believed Stonehenge functioned as a ritual site and calendar based on solar alignments during solstices.
Stonehenge is a prehistoric monument located in Wiltshire, England composed of earthworks and standing stones. Archaeologists believe it was erected around 2500 BC and served as a burial ground from its earliest existence. It went through three phases of construction, with Stonehenge III being the stone circle of sarsen stones still visible today.

Stonehenge is a megalithic monument located on the Salisbury Plain in England composed of 150 enormous stones set in a circular pattern. The monument dates back to around 2000 BC and includes sarsen stones weighing up to 60 tons arranged in a circle within an outer circular earthwork. While its true original purpose remains unknown, theories suggest it was used for ceremonial purposes related to solstices, equinoxes, and possibly predicting eclipses. Stonehenge continues to impress visitors with its ancient construction and enduring mysteries.
Stonehenge is a prehistoric monument located in England composed of a circular setting of large standing stones. Archaeologists believe it was constructed between 3000 BC to 2000 BC in multiple stages. The first stage involved building a large earthwork around 3100 BC. Later, in 2150 BC, 82 bluestones were transported nearly 240 miles from Wales and erected in the center. In 2000 BC, the sarsen stones were brought from 25 miles away and formed an outer circle and inner trilithons. After 1500 BC, the bluestones were moved into their current configuration. Theories suggest it was an astronomical observatory, cemetery, or religious temple.
A monolith is a single massive stone, sometimes moved and incorporated into monuments. Megaliths are large stones used to construct monumental structures. Stonehenge is a famous megalithic structure composed of arranged monoliths. Various Neolithic stone circles and structures from the Bronze Age are described, including Long Meg and her Daughters, Stonehenge, the Ring of Brodgar, and the Adam and Eve longstones. While the original rituals are unknown, megalithic structures were likely created for religious purposes focused on solstices, though uses have changed over time.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

1. Stonehenge, the avenue
Stonehenge, located eight miles north of Salisbury in Wiltshire, England, is a World
Heritage Site consisting of megaliths. It was constructed in three stages between
3100 BC and 1550 BC and was in use until the Bronze Age. The monument is
comprised of a henge, with standing stones arranged in circles. Stonehenge is
believed to be the most significant prehistoric monument in Britain, drawing visitors
since ancient times.
During the first stage, a circular ditch and a ring of 56 pits were dug, known as
Aubrey Holes. The second stage involved the construction of concentric circles
made of huge pillars of rocks from Southwestern Wales. The final stage involved the
erection of 30 upright stones weighing up to 50 tons each, capped by a ring of stone
lintels, enclosing a horseshoe-shaped formation of five Rewritten: The monument
features a horseshoe-shaped arrangement of five pairs of standing stones, with each
pair topped by a stone lintel. DNA analysis reveals that the builders of Stonehenge
originated from what is now Turkey.
2. Stonehenge builders constructed the first stone circle with dolerite stones, known as
bluestones. The builders dug holes that held up to 80 standing stones, but only 43 of
these can be traced today. Theories about how the bluestones arrived at
Stonehenge include long-distance human transport from the Preseli Hills in
modern-day Pembrokeshire, Wales, and the Irish Sea Glacier. The Stonehenge
builders brought thirty huge grey sandstone blocks, known as sarsen stones, to the
site during the later period. They erected these stones in a circle 33 meters in
diameter, with a ring of 30 lintel stones resting on top.
Stonehenge is part of a 'ritual landscape' that includes satellite structures such as
Bluehenge/Bluestonehenge, Durrington Walls, Normanton Down Barrows,
Stonehenge Avenue, Stonehenge Cursus, and Woodhenge. Despite its purpose
being unknown, Stonehenge is believed to serve as a calendar, and some scientists
suggest it may have been an observatory where early rituals or religious ceremonies
took place on particular dates throughout the year.
The ownership and management of Stonehenge are divided between the Crown,
who owns the monument, and English Heritage, who manages it, while the
surrounding land is under the ownership of the National Trust. The World Heritage
Site includes Avebury and Stonehenge together, although they are distinct
monuments.
