THE MAJOR PROBLEMS CONFRONTING AGRICULTURAL MARKETING IN NIGERIA AND SUGGEST ...Folarin Gbolahan
Over the years, major changes came into effect to improve the agricultural marketing system. Many institutions viz., the regulated markets, marketing boards, cooperative marketing institutions, warehousing cooperatives etc., have been established primarily to help the farmers. However, various studies indicated that modernization in agricultural marketing could not keep pace with the technological adoptions in agriculture. The various marketing functions viz., grading, standardization, storage, market intelligence, etc., need to be improved to meet the present day requirements of the farmers. In improving the marketing system for food and livestock in developing countries as Nigeria, it is pertinent to understand the nature of marketing problems as it is only by doing this that workable solution can be found to them. Indeed such knowledge of marketing problems would give information as to why markets are not developing and what measures are required to develop the markets.

Social Work and Social Development in Nigeria - Issues & Challengesguestdfeaacd
1. Nigeria faces many social and economic challenges including corruption, poverty, and lack of infrastructure despite its abundant natural and human resources.
2. Regional disparities exist within Nigeria with social indicators being worse in northern rural areas compared to southern urban centers.
3. While oil wealth generates a large portion of Nigeria's GDP, the country's overdependence on oil has negatively impacted other sectors like agriculture and led to increased poverty and inequality among citizens.
Ebenezer Howard's 1898 work contrasted rural and urban life, proposing "Garden Cities" that incorporated the best of both, such as Letchworth (1903) and Welwyn Garden City (1920). While well-intentioned, garden cities often functioned merely as dormitories for larger cities and did not fully achieve their egalitarian vision. Bid rent theory shows how much different sectors are willing to pay for land in various locations, with retail highest in the city center and residential uses on the outskirts. Variations of this model account for factors like transportation intersections and suburban centers.
The document discusses the history, theory, aspects, and practice of urban planning. It begins with definitions of urban planning and discusses its origins in ancient civilizations. It then covers influential urban planning theories and thinkers from Hippodamus to modernists like Howard and Le Corbusier. The document outlines aspects of urban planning like aesthetics, infrastructure, transportation and discusses sustainable practices. It also discusses new master-planned cities and different levels of urban planning from national to municipal. In the end, it discusses impacts of urban planning on happiness, education and criminality.
Land use planning refers to allocating land resources for different uses consistent with development goals. It involves classifying land, determining suitable land uses, and regulating development through tools like zoning maps and land use plans. The objectives are to promote efficient land use, reconcile conflicts, and guide sustainable development patterns. Land use planning organizations at the national, regional, and local levels coordinate to classify land and guide land allocation and conversion nationally and within their jurisdictions.

Another engineering area highly dependent upon a well-defined Technical Data Package (TDP) is the creation of in-process inspection plans and manufacturing process plans.
DISCUS Desktop enables you to take a TDP and quickly create a consolidated master list of requirements (i.e., the Bill of Characteristics) for the finished part. The DISCUS Planner add-on module adds rich functionality to enable you to assign characteristics to operations, create in-process characteristics for operations, and develop operation-specific process illustrations. DISCUS Planner operates as follows:
You start using DISCUS in the same fashion as used for ballooning of the final part drawing – that is, opening the drawing, dropping balloons, snapping rectangles, etc.
DISCUS Planner adds user interface elements to manage characteristics for each operation in the routing. For example, DISCUS Planner adds a panel for the part routing, operation details, work instructions, etc.
You then assign characteristics to specific operations, even changing the characteristic requirements at a specific operation. As needed, you may create in-process characteristics for an operation that don’t appear on the final drawing. You can create operation-specific illustrations of the ballooned part.
When you're done ballooning, you can export ballooned drawings and inspection characteristics specific to each operation. In addition, if you’re using DISCUS Planner for process planning, you can export the entire package – work instructions, process illustrations, and inspection characteristics – to a richly formatted process plan.
The primary output from DISCUS Planner is a structured and fully completed set of manufacturing planning documentation. This includes a summary routing – and for each operation – the work instructions, inspection sheets, and process illustrations. In addition to these primary features, DISCUS Planner automatically generates an operations analysis for the user to indicate characteristics where-used and “delta” values by operation. This helps to reduce errors by ensuring that all characteristics are addressed during the specific manufacturing steps. The use of DISCUS Planner has reduced the time involved in creating manufacturing planning documentation by upwards of 50%.

Microservice Teams - How the cloud changes the way we workSven Peters
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Why Apache Kafka Clusters Are Like Galaxies (And Other Cosmic Kafka Quandarie...Paul Brebner
Closing talk for the Performance Engineering track at Community Over Code EU (Bratislava, Slovakia, June 5 2024) https://eu.communityovercode.org/sessions/2024/why-apache-kafka-clusters-are-like-galaxies-and-other-cosmic-kafka-quandaries-explored/ Instaclustr (now part of NetApp) manages 100s of Apache Kafka clusters of many different sizes, for a variety of use cases and customers. For the last 7 years I’ve been focused outwardly on exploring Kafka application development challenges, but recently I decided to look inward and see what I could discover about the performance, scalability and resource characteristics of the Kafka clusters themselves. Using a suite of Performance Engineering techniques, I will reveal some surprising discoveries about cosmic Kafka mysteries in our data centres, related to: cluster sizes and distribution (using Zipf’s Law), horizontal vs. vertical scalability, and predicting Kafka performance using metrics, modelling and regression techniques. These insights are relevant to Kafka developers and operators.

I. Problem
The past century has seen many advances in drilling technology. Literatures, books, computer programs
and various other sources have been put together by the brightest minds of drilling professionals.
While the technological know-how has tremendously driven the industry forward, individuals are some-
times overwhelmed by the vast amount of information they receive from different sources of media.
Fig. 1. Knowledge is power
Knowledge is power only when you have access to it in a timely fashion. The internet is loaded
with data, but this data needs to be validated. Different pieces of information are scattered around
in engineering textbooks, SPE series, API Standards, IADC manuals, etc. Almost every engineer
has their own Excel Spreadsheets, which may generate different answers.
Drilling software can predict the torque and drag for deepwater ERD wells, but may not answer the
simple question of the buoyancy factor.
The challenge is to create an all-in-one type of information and knowledge base program. A digital
toolbox that bears the following characteristics:
• Quick to access
• Reliable
• Accurate
• Interactive
• Visually intuitive
• Sophisticate yet simple to use

II. Solution
Now much of the technological advances and engineering applications from four decades of hard
work have been distilled into Dr. DE, a comprehensive collection of drilling engineering tools in a
simple-to-learn and easy-to-use software package.
180+ Functions
You can bid farewell to pawing through handbooks and Excel spreadsheets for answers, because Dr.
DE covers more than 180 functions ranging from the fundamentals of drilling engineering to an ad-
vanced well path design and 3D visualization of the wellbore – a must-have resource for every drilling
engineer and technician to get the job done right.
With an unmatched number of functions and accuracy, Dr. DE allows you to quickly and accurately
perform many daily used engineering calculations. It makes your engineering and sales efforts easier

Dr. DE allows the users to input them in fraction format. The fraction format is as follows: an integer +
“ “ + a fraction, e.g. 9 7/8. Once the user hits the Enter key, the program converts the fraction format
to decimal format. (e.g. 9 7/8 to 9.875)
2. Tubular Database
Dr. DE provides extensive tubular and centralizer databases complemented by a fluid database.
Many functions in Dr. DE require the input of pipe OD, weight and ID, etc. You can input them into the
table directly. Alternatively, you can click the button on the upper right corner of the input table to open
the Tubular Database window.

3. Well Path Design
For a well path design, there are many input parameters involved as well as a myriad of different
combinations. Sometimes the situation may lead to where a valid well path is impossible. Tradition-
ally, the trial and error method can be utilized to obtain the desired design. Dr. DE has an advanced
well path design feature called the Well Path Intelligent System. When this option is checked, Dr. DE
will check the values of the data already inputted and provide a range of the current data in order to
create a meaningful well path. The Well Path Intelligent System will save you a tremendous amount
of time and effort in complicated 2D well designs.
Well Path Group in Dr. DE includes nine 2D well path design functions.
