Potter syndrome is a rare congenital malformation that primarily affects male fetuses;it is characterized by pulmonary hypoplasia, skeletal malformation, and kidney abnormalities. The pressure of the uterine wall due to oligohydramnios leads to an unusual facial appearance, abnormal limbs in abnormal positions, or contractures. The fetus generally dies soon after birth due to respiratory insufficiency. The baby was a live preterm male, born to a 30-year-old multigravida, out of a non-consanguineous marriage via cesarean section. There was no liquor at the time of delivery. The baby did not cry immediately after birth and required resuscitation, followed by mechanical ventilation. Multiple congenital anomalies suggestive of Potter’s syndrome were noted including facial features, flattened nose, low protruding ear, retrognathism, and epicanthal folds with unilateral atresia of the choana. Chest X-ray showed small volume lung fields suggestive of pulmonary hypoplasia, and we had on ultrasonography bilateral polycystic kidney disease on ultrasonography. At 42 hours of life, the baby developed tachypnea and severe chest retractions and died due to respiratory insufficiency. Our case highlights the importance of regular prenatal checks and examinations in each pregnancy, which helps to collect suspected cases and improve knowledge of this syndrome for better management.

Pneumatic tire modeling and validation have been the topic of several research papers, however, most of these papers only deal with pneumatic passenger and truck tires. In recent years, wheeled-scaled vehicles have gained lots of attention as a feasible testing platform, nonetheless up to the authors’ knowledge there has been no research regarding the use of scaled tires and their effect on the overall vehicle performance characteristics. This paper presents a novel scaled electric combat vehicle tire model and validation technique. The pro-line lockdown tire size 3.00 × 7.35 is modeled using the Finite element Analysis (FEA) technique and several materials including layered membrane, beam elements, and Mooney-Rivlin for rubber. The tire-rim assembly is then described, and the rigid body analysis is presented. The tire is then validated using an in-house custom-made static tire testing machine. The tire test rig is made specifically to test the pro-line tire model and is designed and manufactured in the laboratory. The tire is validated using vertical stiffness and footprint tests in the static domain at different operating conditions including several vertical loads. Then the tire is used to perform rolling resistance and steering analysis including the rolling resistance coefficient and the cornering stiffness. The analysis is performed at different operating conditions including longitudinal speeds of 5, 10, and 15 km/h. This tire model will be further used to determine the tractive and braking performance of the tire. Furthermore, the tire test rig will also be modified to perform cornering stiffness tests.

The main purpose of this literature review is to understand the effectiveness and impacts of Robotics Process Automation (RPA) on the practices of Project Management (PM). For attaining the purposes of the research study, an extensive literature review was conducted, which helped in gaining a theoretical understanding. These findings were then justified with the help of current and relevant secondary sources in the analysis section. The findings suggested that RPA is quite advantageous for implementing in varied aspects of a business, especially in the field of project management. However, it can pose several challenges, which need to be taken into due consideration by the organizations during execution such as the capabilities of the employees and the abilities of the existing systems to incorporate automation, among others. It was ultimately concluded that RPA is highly advantageous for project management teams but its effective implementation is the key to success.

The purpose of this research is to investigate the effect of potassium fertilization source and dose on productivity and quality parameters of strawberry. The trial was conducted in 2016-2017 at the experimental greenhouse of Hassan II Institute of Agronomy and Veterinary Sciences in Rabat. Strawberry plants of the cultivar “San Andreas” were planted on November 6th in 12 liter pots equipped with a gravity fertigation system. The experimental design was a split-plot with eight treatment combinations of two potassium fertilizer sources: 1) Potassium Sulphate for the whole growing cycle (PS/PS);2) Potassium Nitrate during the vegetative period and Potassium Sulfate during the fruit production period (PN/PS) and four potassium fertilizer doses: 100, 200, 300 and 400 kg/ha of K2O replicated thrice. Potassium sulfate source was superior to potassium nitrate on the improvement of productivity and quality parameters of strawberry fruit. Potassium sulphate improved the number of flowers by 16%, fruit production by 21%, sugar content by 3%, and titrable acidity content by 0.5 g/L. The highest yield was recorded in plants receiving 300 kg/ha K2O as potassium sulphate. The 300 kg K2O/ha dose gave also superior results regarding quality parameters of strawberry fruit. This optimum potassium dose enhanced number of flowers by 35%, fruits produced by 44%, sugar content by 25% and titrable acidity content by 0.9 g/L.

This paper discusses the impact of e-governance powered by blockchain in the project and program management industry. With the rise in technological innovations, many countries have turned to e-governance for efficiency in service delivery, transparency, and decision-making. E-governance backed by blockchain technology entails improving the public services provision by implementing structures of information and communication technologies. There are many challenges with the traditional project management approach that causes organizations and its stakeholders’ cost and time. Thus, the introduction of blockchain has given many organizations a new approach to adopt in order to eliminate the challenges associated with the typical project management approach. In spite of the cutting-edge technology of blockchain and its broad applications in program management and e-governance, there are still many challenges that restrain its adoption on a broader scale. The research discusses the challenges of the blockchain deployment in the program management field and e-governance in private and government sectors and it highlights the efforts put by both sectors to make use of the technology. Also, the research covers the opportunities and the advantages of a blockchain adoption in various segments. The paper uses various case studies in the UAE, in both private and government sectors, and a qualitative research approach was implemented. The case studies were on government entities such as Smart Dubai and the Ministry of Health Prevention and also private entities like DP World and Emirates NBD. The paper concludes with recommendations and solutions on how to maximize the benefit of blockchain in the program management industry and how it is improving the decision-making process.
