This document summarizes a presentation on using an enclosure method to detect inclusions for the p-Laplace equation from boundary measurements. It introduces Calderon's problem for the p-Laplace equation and discusses prior work. A main idea is to use special oscillating solutions that focus energy on one side of a half-space and define an indicator function based on boundary measurements. It is shown that the indicator function grows exponentially if the inclusion intersects the half-space and decays exponentially if it is outside, allowing recovery of the inclusion's convex hull. Details of the upper and lower bound proofs are provided.

Biofortification as part of multi-dimensional nutrition programmes in Uganda,...International Food Policy Research Institute (IFPRI)
World Vision and HarvestPlus have partnered to promote biofortified crops in Uganda, Burundi, and Bangladesh as part of multi-dimensional nutrition programs. In Uganda, over 105,000 smallholder farmers grew iron beans and orange sweet potatoes, reaching over 40,000 children with nutrition education. In Burundi, 198 tons of iron beans were marketed through value chains and nutrition promotion reached over 1,000 households. In Bangladesh, over 404,000 people, including 5,135 farmers and families, grew zinc-rich rice varieties to improve nutrition. The partnership aims to strengthen efforts to scale up biofortification interventions and access nutrient-rich staple foods in more countries to reduce micronutrient malnutrition.Enrique ochoa
La Unión Europea ha acordado un embargo petrolero contra Rusia en respuesta a la invasión de Ucrania. El embargo prohibirá las importaciones marítimas de petróleo ruso a la UE y pondrá fin a las entregas a través de oleoductos dentro de seis meses. Esta medida forma parte de un sexto paquete de sanciones de la UE destinadas a aumentar la presión económica sobre Moscú y privar al Kremlin de fondos para financiar su guerra.

Setting the Record Straight !!! BUBBLE BUST
ROUGH By Martin Rapaport
The diamond industry is
undergoing fundamental
structural change as the
rough diamond distribution
system self-destructs amid
collapsing rough prices.
Frankly, it’s good news.
Unprofitable, unsustainable and
unfair rough prices have been
the bane of our industry. For too
many years artificially high rough
prices have stolen profits from our
trade. The hard-working cutters, polished
dealers, jewelry manufacturers, designers and
retailers who have honestly added value to diamonds
have not received their fair share of diamond profits.
The major mining companies and the banks have
milked our trade dry by systematically supporting
rough prices that were significantly higher than polished
prices. This effectively moved profits from the trade to
the miners. The banks helped the miners squeeze profits
out of the trade by showering money on firms that
boosted rough prices to speculative unprofitable levels.
The overextension of credit created a situation similar
to what happened in the Real Estate Bust of 2008. Too
much credit created a price bubble that burst when it
became clear that the value of the underlying assets was
insufficient to repay loans.
In the case of the diamond industry, the banks were
complicit in the creation of the rough price bubble
because they consistently lent money to buy unprofitable
rough diamonds. As in the case of the real estate bust,
the banks were more interested in their short-term
profits than the ability of their
clients to repay loans. Once it
became clear that the clients
did not have the assets to
repay the loans, the bankers
chose to continue the
loans as long as the interest
payments were made. They
hoped that at some stage their
clients would accumulate huge
profits that would enable loan
repayment. But the rough borrowers
never got the big profits. De Beers and
the other mining companies kept raising prices
whenever polished prices increased so cutters remained
unprofitable and instead of a polished boom, we now
have a rough bust.
De Beers, ALROSA and the other mining companies
were beneficiaries of the banking boondoggle. They
took short-term profits without thinking about the
long-term negative implications of their relentless price
hikes. Essentially, money was moving from the banks to
the mining companies in a Ponzi scheme environment
involving overpriced rough diamonds supported by
diamond cutters who took the money from the banks
and gave it to the mining companies. Some cutters also
took their cut by setting aside some of the money the
banks so generously gave them. None of the players
who benefited from this game were innocent. Nothing
supported the high rough price levels other than even
higher rough prices supported by unsustainable loans.
The real victims are the legitimate diamond trade that
could not make profits adding value to diamonds because

This is a nanotechnology is a South African product for diesel /petrol engines.
1. Engines last longer, runs cheaper, cooler, smoother and substantially reduced soot and odour.
2. Cost savings 10 to15% ( transport )and up to 28% on generators.
3. Use 3ml naftech to 1L fuel (300ml to 100L diesel )
4. Less GHG ( green house gas ) emissions.
5. Tested by CSIR and SABS approved (SANS 324 for diesel and SANS 1598 for petrol)
Naftech serves on the board of ASTM ( American Society for Testing Materials ) witch sets the international petroleum standards in 53 countries world wide.
Mechanical engineers are in the team for technical assistance.
Geospatial Analysis: Innovation in GIS for Better Decision Making
Discussion led by John Spencer and Mark Janko. This webinar shared new techniques in geospatial analysis and how they have the potential to transform data-informed decision making.
Measuring Impact Qualitatively
The document discusses a webinar on measuring impact qualitatively held by Susan Pietrzyk and colleagues from MEASURE Evaluation and ICF International. It provides an overview of the webinar topics which included reflecting on evaluative efforts to understand and measure impact, the role of qualitative methods, and insights from a review of 32 USAID HIV/AIDS evaluation reports. The document outlines the objectives and approach of the webinar and document review, and shares insights and ideas for understanding and assessing impact qualitatively including considering impact as a subjective concept, specifically describing methods, and thinking about the relevance of experience and unit of analysis when evaluating impact.
Randomization and Its Discontents
This document discusses challenges with evaluating the impact of programs and methods that can be used. Randomization is presented as the ideal approach, as it ensures participants and non-participants are similar on average. However, randomization has limitations in practice, as individuals may not comply with their assigned status or drop out. Experiments also have limited scope and may not generalize to full-scale programs. As a result, other quasi-experimental methods are discussed, but these rely on strong assumptions that may not hold. In general, accurately estimating a program's causal impact is challenging.
