Public procurement denotes the attainment of goods, works, or services required by governments through contracts. Public procurement is usually plagued with covert practices and exclusive forms of corruption in Bangladesh. The cost of development finance is much higher in public procurement than that of others in Bangladesh. There have been no unified rules or laws regarding government purchases since 2006. The Government of Bangladesh enacted its ever first act of public procurement, the Public Procurement Act, 2006 (PPA, 2006), and the Public Procurement Rules, 2008 (PPR, 2008). The procurement entity must disseminate procurement information through electronic medium i.e. Electronic Government Procurement (hereinafter e-GP). Despite passing over an era since its enactment, the role of the PPA, 2006 remains seriously under-researched area, specifically there is no research on the issue of the grievance redress mechanisms. The study has been done using a qualitative case study methodology, backed by both primary and secondary documentary analysis. Based on empirical data, this paper explained the role of digitalization in the process of government procurement and depicted changes that have been brought by the implementation of e-GP in government purchases. However, it concluded that the grievance redress mechanism in the process of procurement is only existing in the policy papers which need mandatory implementation for a transparent and accountable governance system. Despite the significant changes and up-gradation in digital government procurement, it is hardly found that the GRM process is digitalized. And the mass tenderers are yet to be acquainted with the improvised system apart from the consistent efforts of the government.

I am conducting a single-case study research as part of my dissertation for a Master's degree. The topic is in the area of public procurement and innovation. The aim is to explore to what extent standards referenced in public procurement allow innovation in State-Owned Enterprises (in a one country).
The research is designed as a single case-study. As identified by Robert K. Yin in his book Case Study Research, one of the rationales of a single case study is the representative or typical case. As a result, I have arranged for an interview with one procurement professional from the selected organization. However, my supervisor informed me that a single interview will not be sufficient to get unbiased and comprehensive data for analysis and discussion. Additionally, I was advised to conduct surveys if it is difficult to arrange interviews.
I do not understand why is it necessary to involve more than one participant in the research and conduct more than one interview. Also, how surveys are going to help get sufficient data, given that I am conducting a qualitative research. As for data analysis, I am going to use thematic analysis in which I will link what to be said in the interview with my findings from the literature.
I would appreciate it, if you could advice me on what should I do
Relevant answer
Answer
The classic strategy for determining the number of interviews in a qualitative study is saturation, i.e., the point at which no new information is being produced by your interviews. Of course, there is no way to predict this in advance, but if the information you are getting becomes repetitive after 15 interviews, then there is no point in conducting 10 more.

In the specfication to procure a power tranasformer the employer set the core temperate rise is to be 75°C but the supplier wants to supply power transfomer with 90°C temperature rise!
Relevant answer
Answer
One aspect is the transformer core Curie temperature. The working point must be sufficiently far from this temperature. You didn't mention any transformer specifications. The powe're transformer with iron core is at 90 C degree far from Curie point contrary to switching transformer with ferrite core (you need to know exact core material specifications). Then you should checked drop of magnetic properties and losses with temperature increase. It should lead to the thermal runaway as was said at previous answer. Loss of inductance leads to magnetizing current increase. Overcurrent should activate transformer protection or it should limits the circuit operation of the switching power supply due to current limiting function. The transformer itself should be destroyed by insulation system failure due to overheating. The higher grade of insulatin wires must be used to guarantee the same life expectancy.
So if supplier produce the transformer with higher working core temperature he uses better core material and better wires. Usually is such transformer smaller with lower weight and cheaper. On the other hand it should has higher magnetizing current and higher inrush current. I recommend you to check if the magnitude of magnetizing current, total losses, inrush current and temerature safety (coordination with surrounding materials and device cooling system) meets limits of your application.

" Picture a world where every product and appliance is environmentally friendly, where every supermarket item is fair trade, where corruption is an urban myth and poverty a long-distant memory. Hard to imagine?
Technically, it is possible… if everyone adhered to sustainable procurement."
Recently, I found this statement on this website: https://www.csr-company.com/our-services/iso-20400-sustainable-procurement-%E2%80%93-implementation-and-auditverification. Seems like an organisation with a serious mission.
I wondered whether creating this ideal world was really this simple. If yes, why do we not spend MUCH MORE attention to ethics in supply chains, that is with the selling and the buying side. And consider the financial and societal benefits more ethical supply chains would bring. Looking forward to a good discussion. BR Anne Staal
Relevant answer
Answer
I believe improvements in supply chain ethical behaviour requires the party that controls the supply chain to insist on and effectively guarantee adherence to specific standards. It is not always obvious who effectively controls a supply chain, and supply chain control can change. Currently consumers have more control over the supply chains that provide them with products and services than in the past. I feel this trend will continue. Then the issue becomes educating or convincing the consumers which ethical behaviours they require. This has shown itself in campaigns for fair trade grocery products, organic food, responsibly produced apparel, and even organic cotton. I would look forward to discussing this.

I have been search for UVC LEDs recently. However, finding an LED with a peak wavelength below 240nm is becoming difficult. Can suggest a way to obtain an easy solution for this.
I am aware of Excimer lamps. However, procurement of this is difficult in India.
Thank you!!
Relevant answer
Answer
Dear Sreeprasad,
LEDs in this wavelength regime are not commercially available, even though the band gap of AlN is 6.2 eV (210 nm). The main problem is stability and light outcoupling of Al-rich (Al,Ga)N semiconductors.
Radiation sources for the wavelength range below 240 nm are indeed excimer lamps, e.g. KrCl* as a 222 nm emitter. A Xe2* excimer discharge emits at 172 nm, while the spectrum can be modulated by phosphors, e.g. YPO4:Nd (193 nm), LaPO4:Pr (225 nm), YPO4:Pr (235 nm), or YPO4:Bi (241 nm).
Ushio has some of these lamps in their portfolio.

For an all-encompassing test of deep appreciation and ability to use the scientific process you might use Piagetian Formal Operations tasks, like the famous Pendulum Task (link to downloadable simulator below). Just limit your participants to those who haven’t learned the specific facts (usually toward the end of 12th grade Physics). From this task you can see how well students imagine possible hypotheses and plan our systematically testing the possibilities. For specific factual laboratory skills, you might design a battery of multiple-choice questions with one for each skill (e.g., read the level of this graduated cylinder with the correct answer and common mistakes).

Relevant answer
Answer
In Hungary the first public procurement regulation can be discovered in the Act XX of 1897 on State Accounting. Then came other acts in relation with industrial development (Act III of 1907; Act XXI. of 1931). During the socialism, due to nationalization and command economy there was no competition. After the political changes (1990s), instead of amending the incomplete and rough public procurement legislation in force in the early 1990s, a new law was needed. Hungary's first law, specifically on public procurement, is the Act XL of 1995. With our accession to the European Union, the Act CXXIX of 2003 on Public Procurement resulted in full harmonization with EU legislation, which after eight years was replaced by another Public Procurement Act, the Act CVIII of 2011. Due to the transposition of the new EU directives adopted in 2014 and with the aim of introducing a more flexible public procurement regulation, our latest public procurement regulation entered into force on 1 November 2015 Act CXLIII of 2015 on Public Procurement (Kbt.).

I have just procurred the above gamma spectroscopic system for the estimation of Pb-210. I need guidance in this project who has experience in the measurement of Pb-210.
Relevant answer
Answer
As Erik stated, self-absorption is an issue in gamma/x-ray detection.
Especially for quite low energy detection of gammas/x-rays in the presence of high atomic number material. Elements around and a bit above Z=62 will significantly affect the 46keV detection.
So you may share some estimates on the chemical composition of your sample(s).
Thanks in advance

I am assisting in a research project on sustainability in Fashion Design. Specifically, in relation to fashion design practices, fashion curricula and teaching practices at tertiary institutions. For instance, do tertiary institutions teach sustainable fashion design practices to drive sustainable fashion design. This could be in relation to the environmental impact, ethical sourcing, changes in curricula to accommodate this line of thinking. The research may not necessarily be linked to sustainable fashion design, but related industries such as textiles, procurement etc. which I can review as possible source material.
If anyone can suggest reading of previous research, papers, studies etc in relation to any of these concepts, even conceptually, that may assist, I would be most grateful.
Thank you in advance.

@Mubelo,
What a question!. I'm not sure that I can offer any answers.
Who was it who allocated that topic to you? If a member of the Fort Hare faculty, then perhaps you should ask them for advice/support.
If it's something that you've thought of doing, then one needs to think in terms of the size of the thesis as prescribed by the University Regulations, and the length of time available to complete it, and what the financial and other costs are likely to be. Once again, the staff of the faculty would be best placed to help.
Good luck, anyway!

We are in a process of procuring an ageing chamber for studying ageing effect on polymeric insulator specimens. The inner size of the chamber is 100 cm x 45 cm x 45 cms. The specimens will be mounted in the middle of the chamber and the size of the specimens are 120 mm x 50 mm x 6 mm and will be mounted vertical in the chamber. The UV lamp wattage is 30 W. UV lamp emits UV-A of wavelength 340 nm. The lamp will be mounted on the upper most corner of the side wall. How will we be able to calculate the irradiance on the specimens ?
Relevant answer
Answer
Hi,
using the informations you wrote it is not possible to evaluate the UV irradiance on the specimen. The best solution for your question could be the measurements of the irradiance by means of a spectroradiometer wich permit to measure the spectral irradiance nanometer by nanometer and to calculate the irradiance integral on the whole lamp spectrum. You can use also less expensive radiometers, but you need a radiometer with a spectral response close to the lamp spectrum. You say that lamps emits at 340 nm, but probably, it they are fluorescent lamps as I think, it is the wavelenght of the maximum intensity of the spectrum. If you have not spectroradiometer or radiometer, the only way you can follow in my opinion, is to look for people who has a similar experimental apparatus (same lamps, same distance between speimen and lamps, same relative position between lamps and specimen, and so on) and ask them the approximative irradiance (very approximative). Other solution could be to verify if in the technical specifications of the lamp there is the irradiance of such lamp on a surface at a specific distance and then to estimate the irradiance in your conditions.

are correct. I would also like to advance the concept of psychological contract in determining the levels of trust and commitment to project delivery. I have coauthored a couple of papers on this concept. You can have the best contract or the worst contract, the team’s commitment and understanding of psychological contracts will assist in either scenario in my view.

What is the major difference between the freely available CartoDEM from Bhuvan web portal and CartoDEM of ortho image resolution 2.5m which is to be procured from NRSC if needed?
Thank You very much in advance.
Relevant answer
Answer
The CartoDEM and ortho image were generated using CartoSat-1 Stereo pairs (or Stereo Images) by National Remote Sensing Centre (NRSC), Hyderabad. The resolution of CartoSat-1 Stereo pair is 2.5 m. Therefore, the resolution of Ortho image is 2.5m and DEM is 10m. But DEM available in Bhuvan is 30m (The 10m DEM resembled in to 30m). If you want 10m DEM, you have to procured CartoSat-1 Stereo pairs from NRSC and generate DEM and ortho image. All the best.
