Preconsolidation in glacial sediments: the case of Andorra
This document summarizes the geotechnical properties of glacial sediments in Andorra. It discusses two case studies: 1) a lateral moraine where samples showed evidence of multiple consolidation events, and 2) the bottom sediments of an overdeepened valley which exhibited decreasing shear strength with depth, indicating former high water pressures. Pressuremeter tests on these sediments revealed three types of stress-strain behavior: 1) a single yield point, 2) multiple yield points, and 3) continuous yielding without apparent yield points. This provides insights into the stress history and consolidation of glacial sediments in Andorra.

This document summarizes research on the Navamuño depression located in the Sierra de Béjar in western Spain. A variety of geological, geophysical, and geomorphological studies were conducted to understand the origin and sediment fill of the depression. The studies found the depression was formed by tectonic extension along the Puerto de Navamuño strike-slip fault. Glacial activity during the last ice age and post-glacial sedimentation filled the depression. Three sedimentary layers were identified, with the oldest layer of unknown origin and age below younger Pleistocene and Holocene layers. The research provides a chronology and model of formation for the ice-dammed depression within the complex tectonic context.Glaciation in the Eastern Pyrenees between NGRIP/GRIP GS-9 and GS-2a stadials...

Mid-Late Pleistocene glacial dynamics in the Valira valleys (Principality of ...Fundació Marcel Chevalier
Many sediment-covered mountain areas affected by the growth of Pleistocene glaciers are over-consolidated. Palaeoglacial conditions are deduced from glacial consolidation and site investigations. Geomorphological evidence on the glacial extent and history is in this Thesis used as a framework for hydro-mechanical flow simulations in the valley glacier of Andorra and the lower Isère glaciated valley.
By classifying glacial phases of the northern Iberian Peninsula fringe, four common glacial phases arise for the last glacial cycle:
A) An early Glacial Cycle starting at MIS 5d having a recessional period during MIS 5c. Cold-type glaciers are expected to have existed in some of the extreme NW of the Iberian mountains until Termination 1.
B) The Last Maximum Ice Extent occurred mainly during MIS 5a – MIS 4. An asymmetrical glacier recession during MIS 3 was related to an increase in eastward aridity.
C) Significant glacier fluctuations during the MIS 3 – MIS 2 hinge, the appraisal of temperated-polythermal type of glaciers accompanied by a generalised moisture increase entailing valley glaciers to surge.
D) Side-to-side mountain range-scale deglaciation dissymmetry in MIS 2. The widespread expansion of tempered-polythermal type glaciers during the LGM period and Termination 1 had a proportional expansion to the available moisture.
The final deglaciation is characterised by relictual cirque glaciers disappearing during GS-1. In Andorra, a general rise in local river base levels occurred until the Holocene Optimum.
Mid-Late Pleistocene glacial dynamics in the Valira valleys (Principality of Andorra). Asymmetries within the Pyrenees and correlation across the westernmost European mountain ranges.
Unravelling the afore-cited glacial phases and unexpected research allows for a tesselated mapping of the SW continental Europe concerning part, or all of the LGC glacial phases outlined above (Figure 6):
1 – Areas where glaciers were prevalent during MIS 2, like the Iberian Central System, the NW and S French Massif Central, the NW Jura and the maritime Alps.
2 – Areas having a far-flung end moraine produced in a previous glacial phase (MIS 6 or posterior) showing stability until the MIS 2, as for ice caps/fields from the southern half of the Galicia mountains.
3 – Areas of pseudo-pleniglacial or apparent-pleniglacial condition, despite previous glacier recessions phases (albeit challenging to identify), as in most of the northern slope of the Pyrenees.
4 – Areas of multiphase glacier advances, like most of the southern slope of the Pyrenees, most of the Cantabrian Mountains, the half north of the Galicia mountains, the High Atlas, Sierra Nevada and the SW French Massif Central, the western Alps and the Vosges.
5 – Areas where glaciers were present from the LGM until Termination-I, like the northern Iberian range and Sanabria in Iberia. Nevertheless, other mountain ranges have a Type 5 glaciation scenario, like the southern Black Forest in Germany.Chapter1
The document provides an overview of the geological history of Montana from over 4 billion years ago to present day. It describes how continents collided and volcanic activity shaped the landscape, leaving behind fossils and mineral deposits. Glaciers advanced and retreated across the land during ice ages in the Cenozoic era. Geologists can study the layers of rock and fossils to piece together how the physical features of Montana were formed by various geological processes over millions of years.
Folding_Faulting_Volcanism.pptx
This document summarizes key concepts related to orogenesis including folding, faulting, and volcanism. It describes three main types of faulting - normal, reverse/thrust, and transform/strike-slip. Examples of related landforms like horsts and grabens formed by normal faulting are provided. Transform faults like the San Andreas are described as forming shallow linear valleys with little volcanism. The earthquake cycle and seismic wave types are summarized. Historic earthquakes in California like the 1857 Fort Tejon and 1906 San Francisco quakes are overviewed. Finally, the document classifies volcanoes and provides examples of explosive composite cones and effusive shield volcanoes formed at hot spots.
Landform characterization through satellite image
This document discusses different types of landforms created by various geological processes. It describes fluvial landforms such as channels, deltas, and floodplains which are created by rivers and streams. Aeolian landforms like dunes and yardangs are formed by wind erosion, especially in desert environments. Glacial landforms include valleys, moraines, and eskers that are shaped by the movement of glaciers. Finally, marine landforms like barrier islands, deltas, and sea caves occur where ocean waves interact with coastlines. The document provides examples and images to illustrate different landforms around the world.

Rockglaciers genesis and growth in a degrading mountaincryosphere (Southern F...University of the Highlands and Islands
This study analyzed glacial and periglacial landforms in the Southern French Alps to reconstruct the landscape evolution since the last glacial maximum and better understand rockglacier development patterns. Cosmogenic dating and weathering rind measurements identified three post-LGM glacial stages and three generations of rockglaciers. Most rockglaciers likely developed in the second half of the Holocene, and their distribution depended on both climate and geomorphic conditions following glacier retreat. The results provide new constraints on late glacial retreat in the region, suggesting valley glaciers persisted lower than previously thought until the early Holocene.Plate TectonicsChapter 19Plate Tectoni.docx

High Resolution Seq Strat Applied to Field Development
The document summarizes research on the depositional systems and sand body geometry within the Oficina Formation in eastern Venezuela based on well log, seismic, and core data. Key findings include:
1) A high-resolution sequence stratigraphy framework was developed showing stacking patterns related to base level changes in the distal foreland basin.
2) Major reservoir development occurred during lowstand systems tracts (LST) characterized by estuarine incised valley fills and transgressive sand ridges during tidal-influenced periods.
3) Fifth-order sequence boundaries controlled sand body geometry and connectivity, with erosion during lowstands creating incised valleys that compartmentalized reservoirs vertically and laterally within sequences.
Lecture10 platetectonics
Plate tectonics explains how the Earth's crust is made up of plates that move over time. As the plates move, they interact at boundaries where new crust is formed through sea floor spreading at mid-ocean ridges or old crust is destroyed through subduction at trenches. This convection cycle of crust formation and destruction, driven by heat from the Earth's mantle, explains the rock cycle and patterns of geological activity observed at plate boundaries like volcanoes and earthquakes.

1) The study uses detrital zircon U-Pb geochronology on sandstone samples from the Adriatic foredeep ranging from 32-18 Ma to track the indentation of the Adriatic microplate beneath the Central Alps.
2) The ratio of Variscan to Caledonian zircon grains sharply increases at around 24-23 Ma, marking the westward shift of the Adriatic indenter and associated right-lateral motion along the Insubric fault.
3) This suggests the indentation of Adria beneath the Central Alps occurred around 24-23 Ma, providing the first time constraint on major strike-slip motion along the poorly dated Insubric fault.
Plate tectonics
1. Alfred Wegener first proposed the theory of continental drift in 1912, suggesting that the continents were once joined together in a supercontinent called Pangaea.
2. Evidence that supports continental drift includes the matching coastlines of continents, matching fossil and rock formations found on separated continents, and geological evidence of glaciation in currently tropical areas.
3. The theory of plate tectonics combined the ideas of continental drift and seafloor spreading, proposing that the Earth's crust is broken into plates that move due to convection currents in the mantle. Plate boundaries are the sites of important geological activity.
Carboniferous_Permian_paleogeography_of the assembly of pangaea.pdf
This document summarizes the tectonic events surrounding the assembly of the supercontinent Pangaea from the Late Proterozoic to the Early Mesozoic. It describes three general sequences: 1) the breakup of Rodinia and drifting of continents in the Late Proterozoic, 2) the convergence and collisions of continents and terranes from the Ordovician to Devonian forming Laurussia, and 3) the final collisions of Gondwana with Laurussia and Siberia from the Mississippian to Permian assembling Pangaea, with eastern Pangaea assembling into the Early Mesozoic. It also provides a global reconstruction of the tectonic plates
04VolcanicRelief.ppt
Volcanoes commonly occur in belts or clusters at plate boundaries. Forecasting volcanic eruptions involves assessing the character and timing based on the volcano's historic eruptions and measuring parameters like seismic activity, ground deformation, and gas emissions. Determining the timing of eruptions depends on monitoring these precursory signals.
Geology Complete (Earth Science Topic)
This document discusses the theory of continental drift and plate tectonics. It explains that continental drift is the movement of continents across Earth's surface over geologic time. The theory was first proposed in the early 20th century by Alfred Wegener and helped explain the formation of supercontinents like Pangaea and the matching of continental margins. It also introduced the concept of plates and how their movement causes geologic phenomena like earthquakes and volcanoes.
The Late Devonian Mass Extinction Period
The Late Devonian Mass Extinction Period saw at least 70% of species perish approximately 374.5 million years ago, making it one of the "Big Five" mass extinctions in Earth's history. The main victims were major reef builders like corals. Potential causes that have been debated include asteroid impacts, volcanic activity from plate tectonics, and climate change from these events causing global cooling and glaciation. Evidence from Siberia supports the role of volcanic eruptions from the Viluy Traps in driving environmental changes that destroyed marine habitats.
Tectonics: Plate tectonics Introduction
This document discusses key evidence for plate tectonics including matching fossils, rocks, and climate patterns found in different parts of the world. It describes plate boundaries like divergent boundaries where new crust forms at mid-ocean ridges, and convergent boundaries where plates collide including ocean-ocean, ocean-continent, and continent-continent collisions. It also discusses mantle plumes and hotspot volcanism. The key takeaways are that convection currents in the mantle drive plate motions, there are three main types of plate boundaries with different associated features and hazards, and hotspots represent fixed mantle plumes unrelated to boundaries.

This document provides an overview of the geology of the Cuyamaca Mountains in Southern California. It discusses the geological history and evolution of the area, including how volcanic activity and plate collisions led to the formation of the mountains. It also describes some of the common plant and animal species found in Cuyamaca, such as chamise, lemonade berry, California quail, and ground squirrels. Additionally, it examines examples of the different rock types in the Cuyamaca Mountains, including rhyolite, quartzite, and granite. The document serves to educate about the geological features and natural history of this region.
Plate TectonicsChapter 19Plate Tectonics• .docx
This document provides information about plate tectonics and related geological concepts. It begins with an overview of plate tectonics theory, including the three main types of plate boundaries (transform, convergent, and divergent). It then discusses early evidence that supported continental drift, including matching coastlines and shared fossil distributions. Additional sections cover paleomagnetism data, seafloor spreading evidence, characteristics of different plate boundary types, and potential driving forces of plate tectonics like mantle convection. The document concludes by discussing mountain building at plate boundaries and ways plate tectonics may operate on other celestial bodies.
Brettle Et Al 2001
The paper that caused a bit of debate as to whether tides affect deposition in the Carboniferous Pennine Basin. Prior to this there was some evidence, but it was refuted by the main players. The tidal deposits themselves occur in discrete zones - within the TST of wide valley fills, and in mouthbar systems deposited during stillstand/ early TST.
Chapter fourteen
The document discusses various concepts related to plate tectonics and volcanic landforms. It describes plate tectonics theory including evidence for seafloor spreading and subduction. It also discusses plate boundaries, mechanisms of volcanism, types of volcanic landforms such as shield volcanoes and calderas, and volcanic hazards.

2) The ratio of Variscan to Caledonian zircon grains sharply increases at around 24-23 Ma, marking the westward shift of the Adriatic indenter and associated right-lateral motion along the Insubric fault.
3) This suggests the indentation of Adria beneath the Central Alps occurred around 24-23 Ma, providing the first time constraint on major strike-slip motion along the poorly dated Insubric fault.
Plate tectonics
1. Alfred Wegener first proposed the theory of continental drift in 1912, suggesting that the continents were once joined together in a supercontinent called Pangaea.
2. Evidence that supports continental drift includes the matching coastlines of continents, matching fossil and rock formations found on separated continents, and geological evidence of glaciation in currently tropical areas.
3. The theory of plate tectonics combined the ideas of continental drift and seafloor spreading, proposing that the Earth's crust is broken into plates that move due to convection currents in the mantle. Plate boundaries are the sites of important geological activity.
Carboniferous_Permian_paleogeography_of the assembly of pangaea.pdf
This document summarizes the tectonic events surrounding the assembly of the supercontinent Pangaea from the Late Proterozoic to the Early Mesozoic. It describes three general sequences: 1) the breakup of Rodinia and drifting of continents in the Late Proterozoic, 2) the convergence and collisions of continents and terranes from the Ordovician to Devonian forming Laurussia, and 3) the final collisions of Gondwana with Laurussia and Siberia from the Mississippian to Permian assembling Pangaea, with eastern Pangaea assembling into the Early Mesozoic. It also provides a global reconstruction of the tectonic plates
04VolcanicRelief.ppt
Volcanoes commonly occur in belts or clusters at plate boundaries. Forecasting volcanic eruptions involves assessing the character and timing based on the volcano's historic eruptions and measuring parameters like seismic activity, ground deformation, and gas emissions. Determining the timing of eruptions depends on monitoring these precursory signals.
Geology Complete (Earth Science Topic)
This document discusses the theory of continental drift and plate tectonics. It explains that continental drift is the movement of continents across Earth's surface over geologic time. The theory was first proposed in the early 20th century by Alfred Wegener and helped explain the formation of supercontinents like Pangaea and the matching of continental margins. It also introduced the concept of plates and how their movement causes geologic phenomena like earthquakes and volcanoes.
The Late Devonian Mass Extinction Period
The Late Devonian Mass Extinction Period saw at least 70% of species perish approximately 374.5 million years ago, making it one of the "Big Five" mass extinctions in Earth's history. The main victims were major reef builders like corals. Potential causes that have been debated include asteroid impacts, volcanic activity from plate tectonics, and climate change from these events causing global cooling and glaciation. Evidence from Siberia supports the role of volcanic eruptions from the Viluy Traps in driving environmental changes that destroyed marine habitats.
Tectonics: Plate tectonics Introduction
This document discusses key evidence for plate tectonics including matching fossils, rocks, and climate patterns found in different parts of the world. It describes plate boundaries like divergent boundaries where new crust forms at mid-ocean ridges, and convergent boundaries where plates collide including ocean-ocean, ocean-continent, and continent-continent collisions. It also discusses mantle plumes and hotspot volcanism. The key takeaways are that convection currents in the mantle drive plate motions, there are three main types of plate boundaries with different associated features and hazards, and hotspots represent fixed mantle plumes unrelated to boundaries.

This document provides an overview of the geology of the Cuyamaca Mountains in Southern California. It discusses the geological history and evolution of the area, including how volcanic activity and plate collisions led to the formation of the mountains. It also describes some of the common plant and animal species found in Cuyamaca, such as chamise, lemonade berry, California quail, and ground squirrels. Additionally, it examines examples of the different rock types in the Cuyamaca Mountains, including rhyolite, quartzite, and granite. The document serves to educate about the geological features and natural history of this region.
Plate TectonicsChapter 19Plate Tectonics• .docx
This document provides information about plate tectonics and related geological concepts. It begins with an overview of plate tectonics theory, including the three main types of plate boundaries (transform, convergent, and divergent). It then discusses early evidence that supported continental drift, including matching coastlines and shared fossil distributions. Additional sections cover paleomagnetism data, seafloor spreading evidence, characteristics of different plate boundary types, and potential driving forces of plate tectonics like mantle convection. The document concludes by discussing mountain building at plate boundaries and ways plate tectonics may operate on other celestial bodies.
Brettle Et Al 2001
The paper that caused a bit of debate as to whether tides affect deposition in the Carboniferous Pennine Basin. Prior to this there was some evidence, but it was refuted by the main players. The tidal deposits themselves occur in discrete zones - within the TST of wide valley fills, and in mouthbar systems deposited during stillstand/ early TST.
Chapter fourteen
The document discusses various concepts related to plate tectonics and volcanic landforms. It describes plate tectonics theory including evidence for seafloor spreading and subduction. It also discusses plate boundaries, mechanisms of volcanism, types of volcanic landforms such as shield volcanoes and calderas, and volcanic hazards.

Présentation effectué a l'OMMEA de Lyon en Juin 2022 dans la réunion du GRAQAAD Cam-Clay project 2020 - 2021
The AD Cam-Clay project takes its name from the .ad, which identifies Andorra as a country on the Internet and Clay of a recognized constitutive model and widely used in the science of soil mechanics.
The description of the objectives is structured in three sections. Type of research to be developed and the research elements. Brief explanation of the research project and conceptual model. Tools of research to use and case study.
1st) Type of research to be developed:
This project aims to enter the field of fundamental research. The project aims to develop an explanatory and predictive mathematical model. The mathematical model is based on an existing conceptual model that can be improved according to seconds the results obtained in mathematical modeling.
1b) The subject of the research: The subject of the research is a material of a geological or geomaterial nature, widely known in the Principality and geologically called "Till". In the slang of the country this geomaterial is described as "Rock in formation" or "decompose rock" due to its hardness as well as its ability to generate landslides, failures in buildings, cracks in walls, or their ability to confine groundwater. The target geomaterial is a rock and not a rock. It corresponds to a sediment deformed by the old glacier of Andorra and which has a significant amount of untreated data, under the tutelage of the Marcel Chevalier Private Foundation.
Geomaterial behaves differently depending on how it has been previously deformed (with water or without), and the place in the valley where it has been deformed as well as the depth at which it has been deformed. Numerical data on the behavior of geomaterial are known from the results pressure testing. This type of test is standardized and makes it easy to compare results incl s between distant geographical areas.
2a) Summary explanation: The project aims to develop a model that explains the values of deformation, due to the so-called preconsolidation pressure, which is observed in glacial deposits by a given from the small Andorran glacier.
2b) Conceptual model:
The dynamics are related to an accumulation of sediment and acorns at the bottom of the valley of Andorra, accompanied by a flow of groundwater generated by the melting of the ice. This water flow generates a pressure difference between the upper parts of the glacier and the discharge point at its front. In this context, the sediment at the bottom of the valley is submerged within an effort field tangential, developed by the friction exerted by the base of the glacier in displacement.

This document summarizes luminescence dating results from glaci-fluvial and glaci-lacustrine deposits in the southern and southeastern Pyrenees mountains. Three main groups of dates are identified: an early last glacial period (MIS 5), MIS 3, and the last glacial termination (MIS 2 ending). The oldest date is around 141,000 years from a sample in the Segudet valley, providing evidence of a pre-last glacial cycle glaciation during MIS 6. Younger dates range from around 103,000 to 15,700 years, spanning the last glacial period and the end of the last ice age. The results help constrain the timing of glacial advances in the Pyrene
MRS Hidraulic Conductivity and Geomechanics
The document discusses using a geomechanical approach to obtain permeability coefficients (Cpx) from magnetic resonance sounding (MRS) data by relating Cpx to longitudinal seismic velocity (VL). Data from sites in Europe and Africa were used to develop a logarithmic relationship between Cpx and VL for confined aquifers. This approach needs further testing but shows promise as a robust method for hydrogeologists to estimate permeability when pumping tests are limited.

- MRS surveys were conducted on Hansbreen glacier in Hornsund, Svalbard, Norway to investigate the presence and distribution of subsurface water.
- Three types of water signals were identified: 1) High amplitudes and decays in cold ice near the surface, indicating a karstic aquifer; 2) Low amplitudes and decays in temperate ice, with limited water; 3) Moderate-high amplitudes and long decays at depth, from an aquifer beneath the glacier.
- The results provide insights into subglacial drainage conditions and potential permafrost formation, and help link glacial sediments in Svalbard to deglaciation cycles observed in the Pyrenees.Canvis globals i canvi climatic

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.

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.

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.
Recycling and Disposal on SWM Raymond Einyu pptx
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.

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.

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.
