Invasive Species

Why Is Japanese Knotweed Listed As An Invasive Species?

Every homeowner and gardener in the UK agree that Japanese knotweed is undoubtedly one of the most invasive and menacing plants these days. It is no surprise that so many people are worried about this species due to its capability of growing almost anywhere at an incredibly quick rate. More importantly, it can be challenging and costly to eradicate it without the use of chemicals and expert’ support.

In its native country – Japan, the growth of Japanese knotweed can be kept under control by applying different types of insects, thus reducing its devastating impacts. However, the resistance force in the UK is simply not good enough to prevent it from proliferating. Over time, the plant might become extremely destructive and damaging to the ecosystem in your garden and property, not to mention surrounding houses. To understand more why the Japanese knotweed is so bad, keep reading to learn about its spread and growth.

Spread and growth of Japanese knotweed UK presence
One of the main things that make Japanese knotweed a nightmare for every homeowner and gardener in the UK is the speed with which it spreads and grows. More seriously, its roots might penetrate through brickwork or tarmac and compromise the foundations of your house. While the plant will die back to the ground level during the winter, it might shoot up nearly 20 cm, but between April and September it can shoot up by as much as 8 inches per day and reach over 80 inches in height.

The Japanese knotweed does not generate viable seeds, but it would spread through a system of the underground root, which would penetrate up to 160 inches deep and extend for approximately 275 inches. Cut plants and fragments would also result in new growth. So it is highly unlikely that you can eliminate it entirely by chopping or yanking the roots. Instead, you might need the help of professional service and toxic chemicals.

Why is Japanese knotweed listed as an invasive species?
The World Conversation Union lists the Japanese knotweed as one of the worst invasive plants in the world. Its invasive system of root and strong growth might damage architectural sites, retaining walls, paving, roads, flood defences, buildings, and concrete foundations. Also, it might lower the capacity of river channels in carrying water during a flood.

The Japanese knotweed is also a frequent coloniser of the temperate riparian ecosystems, waste places, and roadsides. It can form dense, thick colonies which entirely dominate any other species, making it one of the worst destructive exotics in many countries. The invasion of the species can be partially attributed to the tolerance of a wide range of soil salinity, pH, and types. Its rhizomes might survive a temperature of up to −35C or −31 F.…

Quality Chemical Bunds

What Materials Make Quality Chemical Bunds?

Bunds are important assets in areas where toxic, inflammable, hazardous substances and chemicals are held. They are required under storage tanks or chemicals tanks such that, if the tank leaks, the spilled chemical is retained back in the chemical band. Selection of the best quality bands is becoming one of the challenging decisions that a company faces. It’s due to the advancement in technology and increase in manufacturing industries that have made it difficult to select.

One of the commonly asked questions is, what materials make quality chemical bunds? Chemical bunds are made from steel construction or a molded plastic. The plastic material used is obtained from LDPE (low-density polyethylene) which makes the chemical drums, IBCs, and the containers. Moreover, the plastic chemical bunds are not stable and they’re also static, it makes its transportation hard as they cannot be transported on forklifts. Which is why you should consider steel bunds if the chemicals are not corrosive.

Are the bunds tested?
It’s a requirement that all bands should pass the bunded store integrity test after 3 years. Such a measure is taken to ensure that they can still contain the chemical spill and are also undamaged.

When to use a bund
A bund is used in liquid storage apart from rainwater. For instance, concrete is the main construction material should be provided with a liquid that can withstand the liquid. They can be used in electrical transformers that contain oil, milk processing plants, chemical storage facilities, transport facilities, and any other place where spills occurrence are very common.

Construction of bunds
Bunds are of various types including square, hump, and a ramp. But since they are designed differently, there are factors of consideration. It includes the bulk liquid storage tanks. The material used in bund construction really matters the most at this stage. Bulk liquid transportation is determined by the capacity and material used that it can hold.

Maintenance
It is also important to maintain chemical bunds especially the uncovered bunds. It should always be inspected to maintain its integrity. It is also important for drainage especially for the uncovered bunds to remove the rainwater. Remember, failure of drainage will reduce the bund capacity thus water will mix up with the incompatible chemicals.

Why chemical bunds?
Chemical bunds are environmentally friendly hence, it will assist in protecting your work and make it a safer environment for your workers and clients. More so, the chemicals bunds are of two types, the pallet bunds, and the IBCs bunds. which are very safe as it contains any major leak before spillage. From the discussion above, it is important that you understand all quality bunds are made from either steel or plastic, which depends on the type of chemical contained.…

How to Build a Culturally Diverse Educational Setting

Very interesting measures are being taken to ensure that the structure, nature and quality of teacher education programs remain “fit” and encourage cultural diversity and making use of multicultural toys from nursery up. Here is how to build a culturally diverse educational setting.

First: through program review, subject review, student self-assessment and assessment, these teacher training programs provide ongoing systematic analysis of program data. They use this data to plan and take action to improve the student experience, monitor the impact of measures taken to improve the student experience, and identify areas in which programs can be improved.

This is important because it allows schools, collaborative partners and the university to meet the needs of students, employers and programs. For the responsible person, this may involve: a personal commitment to the data collection process by setting dates and times for data collection and analysis, and writing and submitting reports.

By e-mail or face-to-face, by sending a timely reminder to key personnel of dates and times of submission of data and facilitating and / or coordinating data analysis meetings. The person can also be responsible for the construction of the final report and the implementation of actions based on the conclusions and recommendations.

Second:the leadership of these programs ensures the continued contribution of schools and collaborative partners to the delivery development and improvement process to maintain high quality academic training that closely matches local and employer needs. . This is important because it allows schools and collaborative partners to become fully involved in the program, thus helping to make the delivery tailored to the needs of students and employers.

For the responsible person, this may involve: visiting schools and collaborative partners to keep abreast of changes in these institutions; facilitate and / or coordinate joint schools and collaborative partnership meetings; ensure that appropriate recommendations from schools and / or collaborative partners are implemented and establish an open and frequent dialogue with schools and collaborative partners by keeping e-mail and telephone contacts and adopting a policy of open door “. It can also include actions such as quick replies to e-mails and phone calls.

Third: those who run such programs ensure the continued diversity of cohorts. This is important given the emphasis on diversity and broadening participation in British higher education institutions.

For the person in charge, this may include: developing relationships with the institution’s Access and Partnership Unit and participating in their workshops as a representative of teacher training; be a “visual” presence of the program during “open days” or “initiation days” and make appropriate presentations at such events.

Fourth: the direction of these programs ensures continued support to cohorts of students, leading to improvements in retention and success. This is important because retention of students is a concern, as local British students now have to contribute more financially to their education.

For the manager, this may include: developing close relationships with the student support unit. Refer students to the unit for advice and guidance on immigration issues, personal and social issues, chaplain support and guidance, disability issues, health and medical services, and informal advice on harassment.…
