Published: October 2018

Abstract
Dynamic reservoir simulation models are used to predict reservoir performance, and to forecast production and ultimate recovery. Such simulation models are also used to match historic production. The success of such models depends critically on optimal gridding, particularly vertical definition and the choice of rock parameters, especially relative permeability.
This paper compares simulation results as a function of utilising alternative relative permeability relationships as simulation input:
Unaltered laboratory data Modified Brooks-Corey (MBC) relationships derived by fitting lab data (Lake,1989), including MBC and Sor extrapolation (Stiles, 1994) Relationships based on the more recently derived two-phase Modified Carman-Kozeny (2pMCK) formulation (Behrenbruch and Goda, 2006)
For maximum clarity, comparisons are made on a single layer basis but covering a range of permeability and porosity values, and capillary pressure relationships are based on modelled lab data using the Modified Carman-Kozeny Purcell (MCKP) model (Goda and Behrenbruch, 2011).
Study results show that very different production responses may be realised, depending on the validity of original lab data and choice of modelled relationships deployed. It is concluded that the use of the 2pMCK model in combination with auxiliary investigative tools is optimal in rationalising lab data. Some tested plugs show the influence of heterogeneity, as well as procedural shortcomings and even plug failure. It is shown how such test results can be identified by the 2pMCK model and then optimally modified. In comparison with the MBC model, it is also evident that the use of Corey coefficients may at times be too prescriptive, and even flawed when it is assumed that exponents are only a function of wettability rather than also considering plug heterogeneity and possible lab issues. Relative permeability and capillary pressure data sets are taken from lab results for the Laminaria and Corallina fields, Timor Sea.

Abstract
With the Oil business expanding day by day and with the demand for oil increasing many challenges were introduced, Kuwait Oil Company's South-East Asset (SEK) played a major role in tackling those challenges to meet Kuwait Petroleum Company production targets. In order to ensure operational excellence strategy is implemented, multidisciplinary teams founded (Well Delivery Task Force Team) to ensure the optimization of production and the full utilization of resources available in order to heed for the KPC requirements.
Today Well Delivery TFT has grown to become a symbol of defining success criteria, which goes beyond technology implementation and setting the right framework for efficiency, coordination & commitment by ensuring an effective synergy between different teams of SEK directorate.
Before the Task Force was formed the teams encountered several barriers to centralization plans. Challenges like inter-dependencies, miscommunications, understanding size, time and type of operation workflows, materials availability created strong barriers to an effective plan implementation. This lead to substandard work outcome due to conveying message between one parts of the team to multiple teams located in different locations resulting in time and effort waste and eventually deviate from the desired application. As SEK core business is to meet expected oil targets, it is critical to ensure that the company standards or work practices are preserved and applied irrespective of the challenges.

Abstract
In the recent low oil price environment, a cost-effective solution was proposed to use through tubing bridge plugs to perform water-shut-off (WSO) in an offshore field. The solution consisted of using slickline to set a plug with a high expansion ratio followed by a cement dump. After three WSO jobs in different wells, the method has successfully proven itself. Watercut was reduced from 100% to 0% with a minimal cost of only USD100,000.
The through tubing bridge plug used is capable of passing through 2-7/8-in. tubing and expanding into 9-5/8-in. casing. After running a Gamma-Ray log, the plug was set across the perforation interval to give the anchor contact with a rough casing surface. The top of the plug, however, was above the perforation interval and became the base for cement. Cement was then continuously dumped on top using a slickline dump bailer in a static condition until the designed cement height was reached. Static conditions ensured no movement of cement during operation. The plug differential pressure limit is directly proportional to the cement height.
The first WSO job was a complete success with watercut reduced from 100% to 0%. The second job however, was partially successful as the cement dump was not completed due to unexpected appearance of a hold-up-depth (HUD). The HUD was created by leftover cement which had accumulated at the end of the tubing. Despite the setbacks, the end result was successful in reducing water production from 1000 bwpd to 200 bwpd. The third job faced a completely different problem. The original plug fell off deeper into the well after it was set. To rectify the situation, a second plug was set at the target interval. Despite the successful execution, there was no change in watercut after the well was brought back online. Since the same method was proposed for another upcoming well, Memory-Production log (MPLT) coupled with Temperature-Noise log was performed to assess the effectiveness of the WSO. The log results confirmed that the WSO was successful and the post job water production was caused by channeling behind the casing. The results so far concluded that the through tubing bridge plug WSO method was both reliable and cost-effective. It is exceptionally suitable for zones located at the bottom of a well and can be deployed using slickline.
The paper provides valuable insight to a WSO solution which should be a first-choice option due to its relatively inexpensive cost and high reliability. The solution has proven to provide tremendous cost saving for production enhancement activity.

Published: October 2018

Objective:
Mature coconut water (MCW) is a waste product from the coconut milk industry. It is sour and unpalatable, yet it contains sufficient nutrients for microbial growth.

Methods:
Four Lactic Acid Bacteria (LAB), namely L. acidophilus B0258, L. brevis VM1, L. casei B0189, and L. plantarum B0103 were used to ferment MCW over 120 h. Among these LAB strains, only L. casei was capable to grow well with the highest viable bacteria count of 1 x 1011 colony forming unit (cfu)/ml. Although all LAB produced α-aminobutyric acid (GABA) after fermentation, L. acidophilus and L. plantarum produced the highest amount of GABA with the increment of 35.4%±7.9 and 38.9%±1.7, respectively. Other amino acid profiles of fermented MCW were also investigated, but most of them were consumed by the LAB. Both L. acidophilus and L. plantarum utilized the most essential amino acids. Within the first 24 h, GABA content was enhanced in all LAB strains when they were actively growing.

Result and Conclusion:
This study showed that both L. acidophilus and L. plantarum have great potentials to increase GABA content in MCW. Fermented coconut water can be formulated as a healthy functional drink as GABA is known to have therapeutic value in alleviating stress as reported by past research findings.

Published: October 2018

Introduction:
Newborn cellulitis is rare and often atypical disease. It is a diagnostic and therapeutic emergency and its progress leads to instant death. We report three cases of neonatal cellulitis from the Neonatal ICU Department of Mohammed VI university hospital in Marrakesh, highlighting this rare, serious and unknown disease.

Case 1:
17-day-old female newborn admitted for sepsis and breast refusal since 5 days. Clinical examination revealed a hypotonic newborn, hypothermic at 34.2 °C with sclerema neonatorum. Skin examination found Erythema and edema on the left hemi-face with necrosis of the ipsilateral nostril. The blood culture had isolated coagulase-negative staphylococci. The newborn was put under triple antimicrobial therapy of 3rd Generation Cephalosporin (3GCs), gentamicin and vancomycin with good progress.

Case 2:
20-day-old male newborn, was circumcised ten days before admission, had sepsis with a fever at 40 °C evolving since 24h. The clinical examination found hard, hot and very painful inflammatory lesion starting at the scrotum and extending to suprapubic region and the start of the lower limbs. Blood tests revealed strongly positive infectious status. The progress was positive when put under triple antimicrobial therapy.

Case 3:
25-day-old female newborn, visited a traditional healer who gave her a mixture of unknown nature to apply on her face, hospitalized in our department for cellulitis of the right hemi-face extending to the periorbital and cervical region evolving since two days together with a fever. Infectious blood assessment was positive. The progress was favorable when put under triple antimicrobial therapy.

Conclusion:
Cellulitis is a rare disease in newborn and it must be diagnosed early because it can be complicated into sepsis. The search for other localizations, mainly meningeal, is essential.

Authors: AbuRuz Mohannad Eid , Al-Dweik Ghadeer 
Published: October 2018

Background:Cardiovascular disease is the first leading cause of death worldwide. Coronary heart disease is the most common manifestation of cardiovascular disease. Acute myocardial infarction is the primary manifestation of coronary heart disease. Depression is a common and predicted complication after acute myocardial infarction. Limited studies evaluated gender differences in depressive symptoms after acute myocardial infarction especially in developing countries.Objective:The study aimed to determine whether there was a difference in depression levels and rate of complications based on gender early after acute myocardial infarction.Method:This was a prospective comparative study on 230 patients (150 men and 80 women) with a confirmed diagnosis of acute myocardial infarction. All participants signed an informed consent, filled sociodemographic and clinical questionnaire and the Depression Subscale of the Hospital Anxiety and Depression Scale. Clinical data were abstracted from the participants’ medical record after discharge.Results:Eighty-six participants (37.4%), 54 men and 32 women, developed 1 or more complications during hospitalization. Female patients were more depressed (14.4±3.5vs.8.3 ± 2.6) and developed more complications (1.9 ± 0.9vs.0.8 ± 0.5) than male patients did. Depressive symptoms increased the occurrence of complication by 40% and 33% for female and male patients respectively after controlling for sociodemographic and clinical variables.Conclusion:Depressive symptoms independently predicted complications after acute myocardial infarction in both men and women. The inclusion of depression assessment tools in acute myocardial infarction treatment protocols is highly recommended.

Thirty yellow maize inbred lines were selected from different source populations and planted in isolation with common male testers (YD-2 and YD-4) in 1:4:1 ratio at Cereal Crop Research Institute (CCRI) Pirsabak, Nowshera during spring-2014 (season–I). On the bases of best seed setting and other important traits, eighteen test-crosses were selected using line × tester approach. The developed 18 test-crosses, nine parental lines and two testers along with two check cultivars (Sarhad Yellow and CS2Y10) were grown in summer season-2014 (July – November) using two replications.Data were collected on various maturities and yield related traits via; days to pollen shedding, silking, ear height, plant height, 100-kernel weight, kernel row ear-1 and grain yield. Significant differences were observed among test-crosses for yield related traits mainly 100-kernel weight and grain yield. L-9 using YD-4 as a tester revealed minimum days to pollen shedding (50.5 days) and days to silking (52.5 days). L-3 using YD-2 as a tester recorded maximum plant height while, L-9 using YD-4 as a tester obtained maximum ear height and length. L-9 using YD-4 as a tester revealed high 100-kernel weight, grain yield and high GCA effect, while L-8 using YD-4 as a tester recorded high SCA effect for 100-kernel weight. L-9 exhibited high GCA effect for grain yield while, high SCA effect was obtained for L-2 using tester (YD-2). L-9 using tester YD-4 revealed maximum mid-parent and best-parent heterosis for ear length and grain yield. For maximum traits, L-9 was the best combiner followed by L-3 and L-6 using the same tester (YD-4) under conducted study.

The Evolution of Knowledge: Rethinking Science in the Anthropocene
Authors: Renn Jürgen 
Published: October 2018

Abstract
The paper argues that humanity has entered a new stage of evolution: epistemic evolution. Just as cultural evolution emerged against the background of biological evolution, epistemic evolution began as an aspect of cultural evolution and now dominates the global fate of humanity. It is characterized by the increasing dependence of global society on the achievements and further extension of science and technology in order to ensure its sustainability in the age of the Anthropocene. The historical development of knowledge is reviewed from an evolutionary perspective that introduces key concepts of an historical epistemology.
Characteristic trace fossils from Miocene brackish-water deposits in the Niger Delta, Nigeria
Authors: Ezeh Sunny C. , Mode Wilfred A. , Ozumba Berti M. 
Published: October 2018

Abstract
Miocene deposits in the eastern portion of the Greater Ughelli, Central Swamp and Coastal Swamp depobelts contain well-developed brackish-water trace fossil assemblages. Twelve ichnogenera have been identified, namely: Asterosoma, Bergaueria, Chondrites, Gyrolithes, Thalassinoides, Lockeia, Palaeophycus, ?Conichnus, Planolites, Siphonichnus, Skolithos and Diplocraterion. In addition, common non-descript, passively filled burrows and fugichnia (escape structures) have also been observed. The above-mentioned ichnogenera and associated non-descript structures can be arranged into six distinct and recurring ichnoassociations within the Greater Ughelli, Central Swamp and Coastal Swamp depobelts. Each ichnoassociation is comprised of a group of trace fossils which collectively reflect specific environmental conditions during deposition of these Miocene strata. All trace fossil assemblages illustrate deposition in nearshore, restricted settings. Ichnological and sedimentological criteria which may be utilized to recognise brackish-water deposits are discussed and illustrated in pictures of the cores studied.

Abstract
Information on Jurassic palynomorphs from the Greater Caucasus is potentially of great importance, but its availability to the international research community is severely limited. New palynological data for Toarcian deposits of the Western Caucasus are recorded in the present paper. Particularly, dinoflagellate cysts are described for the first time from the Bagovskaja Formation; palynomorphs are found in sandstone levels within this unit. The most representative assemblage includes pollen (with predominant bisaccate pollen), spores (Cyathidites being commonest), and dinoflagellate cysts amongst which the predominant taxon is Nannoceratopsis spiculata. The dinocyst assemblage implies a late Toarcian age for the upper part of the Bagovskaja Formation. On the basis of these new palynostratigraphical results, the range of the formation is extended; previously, only the lower part had been dated on ammonite evidence.
Prospects and limitations of heavy mineral analyses to discriminate preglacial/glacial transitions in Pleistocene sedimentary successions
Authors: Zieliński Tomasz 
Published: October 2018

Abstract
The present study revolves around the identification of the stratigraphical boundary between Pleistocene formations that formed prior to the first advance of the Scandinavian ice sheet (Early Pleistocene, i.e., the so-called preglacial) and the overlying, glacially derived deposits (Middle Pleistocene). In particular, it focuses on variation in heavy mineral assemblages, which are an important tool for stratigraphers. The Neogene basement, described here, was most often the source of material that was redeposited by Early Pleistocene rivers. The geological structure and Early Pleistocene palaeogeographical scenarios for various Polish regions are discussed. Moreover, comparisons with other European preglacial formations are carried out. The mineral spectrum of Lower Pleistocene deposits is largely dependent of rocks of the Neogene and Mesozoic basement. If the incision of ancient catchments was into terrigenous rocks, the stratigraphical boundary between preglacial and glacial formations is easily determined with the help of a heavy mineral analysis. As a rule, this coincides with a noticeable change from resistant to non-resistant mineral associations. Such cases are noted for successions in central Poland and eastern England. On the other hand, outcrops of igneous or metamorphic rocks exist within preglacial river catchments in most parts of Europe. They were the local sources of non-resistant heavy minerals long before their glacial supply from the Baltic Shield. In these cases, mineralogical analysis fails in the search for the Early/Middle Pleistocene transition.

Authors: Tarnapowicz Dariusz 
Published: October 2018

Abstract
The increase of energy efficiency in autonomous marine generating sets improves the overall efficiency of the ship’s propulsion. One of the methods to increase the efficiency of generating sets is the use of synchronous machines with permanent magnets in sets as generators (PMSG). The use of PMSG in connected with the need to install power converters in order to maintain constant parameters of the supply voltage and the possibility of reactive power’s distribution between generating sets that work in parallel. The article presents the possibility of using transformer multi-level inverters in parallel operation of marine generating sets with PMSG. On the basis of the results of simulation tests, the theoretical assumptions for the possibilities of active and passive power adjustment in the parallel operation of generating sets were confirmed.
Problems of Friction Force Measurement between Cylindrical Outdoor and Internal Slide Parts
Authors: Monieta Jan 
Published: October 2018

Abstract
The article presents the determination of an exemplary measure in the assessment of the technical state of sets of mechanical objects at the stage of manufacture, use and maintenance. The technical state of the assemblies is influenced by the quality of the friction-cooperating elements, the quality of basic functions, the surroundings and the diameter clearance of kinematic node components. Energy wasted to overcome the frictional resistance is a significant part of the energy supplied, which is why current friction losses are minimized. The article includes analysis of the phenomena occurring in the cylindrical pairs in the presence of static and kinetic friction. The many factors affecting the course and values of friction force between cylindrical elements performing relative reciprocating motion have been indicated. The subject of the article is the method of measuring the friction force between a fixed and movable cylindrical element of the mechanical object. The gradual increase of the friction force component takes place by means of easily accessible force. The results of experimental tests of the friction force in different laboratory conditions under are also included. The effect on the measured friction force was investigated: of friction elements geometry and the surface condition after manufacture and/or operation. Scatter results of static friction force depending on the geometry and surface state can be significant. Examples of surface state images are shown. A friction force model was also developed depending on factors affecting its value.
