Splenogonadal fusion; a rare histopathology report of a pediatric patient[ ]


In 1883, was the first description of splenogonadal fusion (SGF) by Bostroem, which is a rare developmental anomaly of an abnormal connection of splenic tissue with gonads or mesonephric remnants. SGF is of two types; continuous or discontinuous. Almost none of the reported cases have been diagnosed preoperatively, they mainly discovered coincidently during surgeries like orchiopexy and inguinal hernioplasty. We report a case of 12-year old boy presented with history of the absence of testis since birth. Upon physical examination, a mass felt in the left inguinal region raising a possibility of being testicle while the right one was impalpable. Laparoscopic left inguinal exploration and orchiepexy have been done. Histopathology report of a removed mass then revealed ectopic splenic tissue fused within the residual testicle with no increased mitosis or neoplastic features have been identified. Although only 175 SGF reported cases have been found in literature, the condition should be considered in differential diagnosis for every testicular mass. Recommend using such advanced facilities for those patients upon diagnosis like tumor markers, 99 m Tc-sulfur colloid liver spleen scan, inguinal incision and possible biopsy before surgery to avoid unnecessary orchiectomy.

Hedging the risk of productivity loss in financial operations[ ]


In Operations analytics, key parameter is how business operation runs in relation to the assigned performance targets. Key dimension here is performance rate which defines the throughput for a given unit of time. Some level of productivity loss is always accounted for during planning and thus risk here is negative deviance from the expected productivity loss. It’s important for any organization to manage tradeoff between costs of deploying additional resources Vs having effective risk controls implemented. This becomes more of a cost benefit analysis and to strike balance between both becomes important. Paper leverages Loss distribution approach from operational risk space to model Risk of unexpected productivity loss. The approach results in a Full time equivalent contingency plan in form of human capital requirement for worst case scenario and provides an optimal resource plan to manage risk. If required resource pool is less than the optimal, it exposes business to the risk of increased Turnaround times, while if the same is above optimal level it adds to overall cost of the firm.

Simulating the Performance Variability matrix using Markov chains[ ]


In Operations performance analytics space, specifically into financial services firm we measure the associate or functional performance in form of performance rate which is the magnitude of requests processed per unit of time. Utilization is another key metrics that measures the time spent on core processing work as a percentage of the total time spent on core and the non-core work. Basis these key KPIs in relation to the variability of performance we map the associates into 4 performance states where each state provides the unique performance insight to line managers for better planning. The assumption here is that the performance rate and utilization levels at time “t” are independent of the past and only depend on the “t-1” state. Hypothesis for the same is that every interval of time may have different work complexity and business environment under which financial operations would function and thus assuming the same to be stochastic in nature. We then use the Markov chain application to make relevant business inferences and forecasts for the defined performance states.

COMPARATIVE STUDY OF THE RHEOLOGICAL PROPERTIES OF LOCAL CLAY (AFUZE) AS A POSSIBLE REPLACEMENT FOR IMPORTED BENTONITE IN DRILLING FLUIDS FORMULATION[ ]


Drilling fluids (muds) are complex fluids consisting of several additives. These additives are added to enhance/control the rheological properties (such as density, viscosity, yield point and gel strength) of the drilling mud. These properties are controlled for effective drilling of an oil or gas well. In this project work, the rheological properties of locally sourced Bentonite clay from Afuze in Edo state was investigated as a possible substitute for imported Bentonite clay. This was carried out by the comparative analysis of the parameters of the local clay mud with the imported bentonite mud to ascertain the level of compliance in drilling operation. This research work focused on three additives: barite, Pac R (Polyanionic Cellulose Regular grade), and sodium carbonate (Na2CO3) to compare the density, pH and rheological properties of local clay mud and bentonite mud. At the end of the laboratory analysis, the result obtained showed that there was a slight difference in the rheological properties of the formulated drilling mud and the pH values when compared to that of bentonite. Therefore it was concluded that the clay exhibits good rheological properties when compared to imported bentonite.
