Productivity, nutrient concentration, uptake and quality of Amaranthus (Amaranthus cruentus L.) as influenced by cutting heights and fertilizer type
Authors: FALODUN Ehizogie J. , EDAFE Vivian E. 
Published: September 2020

Amaranthus cruentus L. is a leafy vegetable that is cultivated mainly for its leaves and grains. Due to high demand for this crop in Nigeria, the need to boost its productivity becomes necessary. Field and laboratory studies were conducted during in two successive cropping seasons at the experimental farm and laboratory unit of the Department of Crop Science, Faculty of Agriculture, University of Benin, Benin City. Three cutting heights C1: (10 cm), C2: (15 cm), C3: (20 cm) and a control C0: (no cutting) and four rates of fertilizer application F0: (Control), F1: (10 t ha-1 poultry manure), F2: (150 kg ha-1 NPK15:15:15) and F3 (75 t ha-1 NPK 15:15:15 + 5 t ha-1 poultry manure) constituted the treatments. The treatments were in three replicate laid out in a (4 × 4) factorial arrangement in a randomized complete block design. Data collected were plant height (cm), leaf area (cm2), stem diameter (cm) and number of branches. Fresh and dry herbage yield were taken at harvest. Growth, yield, and quality of Amarathus cruentus were significantly influenced by cutting heights and fertilizer application. In both years, number of branches (3.50 and 6.01) were lowest at C0 compared with other treatments. Herbage fresh and dry yield (49.10 t ha-1 and 18.20 t ha-1) were highest at C3 and was consistent in both years. Similarly, the concentration of K, Ca, and Mg in plant tissue and the uptake of nutrients (N, P, K, Ca, Mg, and Na) increase at C3 compared with other treatments. F3 significantly (p<0.05) produced highest dry herbage yield (13.08 t ha-1and 25.15 t ha-1) in both years. Crude protein, fibre and fat content of the shoots were highest at cutting height of C3 and at F3 fertilizer rate. Therefore, for good yield and better quality of Amaranthus cruentus L, a combination of (75 t ha-1 NPK 15:15:15 + 5 t ha-1 poultry manure) at cutting height of C3: (20 cm above soil level) is recommended for Amaranthus cruentus L production in the study area.

Authors: Feder Judy 
Published: September 2020

This article, written by JPT Technology Editor Judy Feder, contains highlights of paper OTC 30525, “Toward a Recovery Ambition of More Than 70% for the Johan Sverdrup Field,” by Eli Eikje, SPE, Tone Nedrelid, and Elisabeth Bratli, Equinor, et al., prepared for the 2020 Offshore Technology Conference, originally scheduled to be held in Houston, 4-7 May. The paper has not been peer reviewed. Copyright 2020 Offshore Technology Conference. Reproduced by permission.
Before the giant Johan Sverdrup barrel of oil, operator Equinor and its license partners set a recovery ambition of greater than 70% for the field. The complete paper discusses key elements driving this ambition. These include the field size and reservoir characteristics, early assessments and investments for improved oil recovery (IOR), data acquisition, reservoir monitoring, and digitalization.
Introduction
With a recoverable volume range of 2.2-3.2 billion BOE, Johan Sverdrup is a giant oil field approximately 150 km west of Stavanger, the third-largest oil field on the Norwegian Continental Shelf (NCS). The reservoir features hydrostatic pressure and undersaturated oil with a low gas/oil ratio (GOR). The first phase of the field came on stream in October 2019. A predrilling campaign included eight oil producers and 12 injectors.
The field is being developed in two phases. Phase 1 includes four bridge-linked platforms:
Living quarters with utility-system functions
Process platform
Drilling platform
Riser platform (RP) with tie-in of onshore power
Three injection templates are tied back to the RP. All platforms have jacket substructures. Main power to the field is from shore. The full field development includes 64 platform and subsea wells.
Phase 2 of the development was approved in 2019 and is expected to start production in Q4 2022. It includes development of another processing platform, modifications of the RP and the field center, five subsea production and injection templates, and power-from-shore supply. The central area with highest hydrocarbon thickness and the highest relief to the free water level was chosen for the field-center location.
Liquid-Redox Process Used for Sulfur Removal on an FPSO
Authors: Carpenter Chris 
Published: September 2020

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper 2019-1016 OMC, “Sulfur Removal on an FPSO: A Liquid-Redox-Process Case Study,” by William I. Echt, Merichem, prepared for the 2019 Offshore Mediterranean Conference and Exhibition, Ravenna, Italy, 27-29 March. The paper has not been peer reviewed.
Eni began producing oil reserves from the Aquila reservoir in the Adriatic Sea soon after its discovery in the early 1980s. As primary production decreased, a decision was made to begin enhanced recovery with artificial gas lift. With the play in deep water (815 m) and 46 km off the southern coast of Italy, a floating production, storage, and offloading (FPSO) vessel was needed. After a 5-year run, the Firenze halted operations in 2018 because of low oil production. The complete paper examines the decision to use hydrogen-sulfide- (H2S) removal technology, the cost of operation, and the unit’s availability over its lifetime.
Introduction
As the industry searches for reserves in ever-deeper formations, the requirement of contending with sulfur increases. Several H2S-removal technologies are available, including nonregenerative liquid scavengers (triazine-based), nonregenerative solid-bed absorbents, and the regenerative liquid-reduction/oxidation (redox) process. These technologies remove sulfur from associated gas streams and do not release them to the environment. The nonregenerative technologies are often referred to as scavengers.
Process Evaluation
During the initial design phase, several H2S-removal technologies were evaluated per the following criteria:
Turndown capability
H2S-removal efficiency
Degree of operator involvement required
Maintenance requirement and waste material produced
Proven reliability in marine conditions
The evaluation led to the selection of the liquid-redox process after it received the highest marks in four of the five criteria. Both liquid and solid H2S scavengers were considered as alternatives to the liquid-redox process for this installation. The considerations for each criterion are detailed in the complete paper.

Published: September 2020

Abstract
Background: Four-dimensional hysterosalpingo-contrast sonography (4D-HyCoSy) is the preferred way for evaluating fallopian tubal patency and it associated with higher rate of spontaneous conception. However, Few studies have evaluated the influencing factors of spontaneous conception in 4D-HyCoSy and suggested ways to choose treatment options after 4D-HyCoSy. The study was to evaluate the correlation between spontaneous conception outcome and the patients’ clinical characteristics as well as tubal patency in infertile women to provide reference on ways to manage the patient after 4D-HyCoSy.Methods: This was a retrospective study and analysis of two hundred and eighty three (283) infertile patients who underwent a 4D-HyCoSy between December 2014 and October 2017 in our center. Eligible patients were those whose partners semen parameters were normal when based on World Health Organization(WHO) criteria, and had spontaneous conception without clinical interventions after 4D-HyCoSy.Result(s): One hundred and sixteen patients (40.9%) conceived spontaneously and the mean conception time was (8.8 ± 0.3) months. Within a year after 4D-HyCoSy, the spontaneous conception rate was highest in type VI(62.5%), followed by type IV (46.2%), type III (44.4%), type V (39.4%), type II (33.9%) and type I (14.8%). With Cox regression analysis, two factors associated with spontaneous conception outcome appeared to increase spontaneous conception rate: patients with type IV or type VI tubes and duration of infertility less than 2 years. The age, type of infertility, multiparas, history of pelvic surgery, history of uterine cavity operation, uterine fibromyomata and polycystic ovary were unrelated to spontaneous conception outcome after 4D-HyCoSy.Conclusion(s): This study showed that some infertile women could succeed in spontaneous conception after 4D-HyCoSy. Hence, We recommend the usage of 4D-HyCoSy as first line for tubal patency test and infertile patients should be advised to accept 4D-HyCoSy examination as soon as possible. Expectant treatment of about 8-9 months is reported to be feasible for infertile women whose 4D-HyCoSy findings showed one tube patency or poor patency. Alternatively, an immediate clinical intervention is recommended for those with bilateral obstructed tubes .
