The African continent (specifically its overwhelming in(animate) resources) is often referred to as the sleeping giant by magazines, blogs, research presentations and articles, and NGOs [such as World Bank]. Reasons for this moniker/title include the continent’s plentiful natural resources, its large and quickly growing young population, and the young population’s quick adoption and acclimatization to technology. Most countries on the continent are known as developing countries due to lack of access to safe drinking water, reliable electricity and roads, sanitation and hygiene, and a high number of people with tropical/infectious diseases. However, due to the usefulness of cellular phones and technology, several countries and companies within them have focused on cell phone proliferation (91% in Kenya). Smart phone usage allows Kenyans access to the world’s information and potentially endless innovation. Given that a large number of Kenyans with smartphones use social media, coupled with the advent of Europe’s GDPR (general data protection regulation), African identity and its associated data became an area of great interest. As the world is quickly progressing into a digital economy, a solution must be created that allows us to regain and control our identities, doing our best to ensure losing such is infinitely close to computationally and probabilistically impossible/improbable. Developing a blockchain-based identity backbone using biometrics and historical family information while allowing government-based identification documents is the best way forward. Three stages have been identified as necessities to accomplish the development of this system before opening it further beyond the pan-African worldwide community. The three stages are defined by systems that allow for biometric/demographic registration (stage 1), interoperability and security hardening (stage 2), and biometric modality data analysis/organization/association (stage 3).

Gene Expression Levels

Breeding and seed production activities in oil palm have been hampered because of the inability of the male parent Pisifera to produce male inflorescence as source of pollen under normal conditions. Researchers are using complete defoliation to induce male inflorescences, but the biological and molecular processes responsible for this morphological change are yet to be revealed. To understand the underlying network of genes that initiate and control this phenotypically documented activity, we initiated a study aimed at identifying differentially expressed genes (DEGs) in three stages of an oil palm inflorescence under complete defoliation stress using RNA-seq. Sequencing on an Illumina platform produced 82 631 476 reads consisting of 8 345 779 076 bases. A total of 60 700 genes were obtained after transcript filtering and normalisation and 54% of them were downregulated. Differences in gene expression levels were significant between tissues under stress. The farther the distance between tissues, the more DEGs recorded. Comparison between stage 2 and stage 1 induced 3893 DEGs whereas 10 136 DEGs were induced between stage 3 and stage 1. Stress response genes and flower development genes were among the highly expressed genes. This study suggests a link between complete defoliation and meristem differentiation from vegetative to reproductive phase in oil palm.

Developement of computer technology provides much improvements on electron microscopy, such as simulation of images, reconstruction of images and automatic controll of microscopes (auto-focussing and auto-correction of astigmatism) and design of electron microscope lenses by using a finite element method (FEM). In this investigation, procedures for simulating the optical properties of objective lenses of HREM and the characteristics of the new lens for HREM at 200 kV are described.The process for designing the objective lens is divided into three stages. Stage 1 is the process for estimating the optical properties of the lens. Firstly, calculation by FEM is made for simulating the axial magnetic field distributions Bzc of the lens. Secondly, electron ray trajectory is numerically calculated by using Bzc. And lastly, using Bzc and ray trajectory, spherical and chromatic aberration coefficients Cs and Cc are numerically calculated. Above calculations are repeated by changing the shape of lens until! to find an optimum aberration coefficients.

Abstract Objectives: This exercise aimed to validate New Taipei City’s strategic plan for a city lockdown in response to COVID-19. The main goal of all solutions was the principle of “reducing citizen activity and strengthening government control”. Methods: We created a suitable exercise, and creating 15 hypothetical situations for three stages. All participating units designed and proposed policy plans and execution protocols according to each situation. Results: In the course of the exercise, many existing policies and execution protocols were validated to address. Situations occurring in Stage 1, when the epidemic was spreading to the point of lockdown preparations, approaches to curb the continued spread of the epidemic in Stage 2, and returning to work after the epidemic is controlled and lockdown is lifted in Stage 3. Twenty response units participated in the exercise. Although favourable outcomes were obtained, the evaluators provided comments suggesting further improvements. Conclusions: Our exercise demonstrated a successful example to help policy making and revision in a large city over 4 million population during COVID-19 pandemic. It also enhanced participants’ subject knowledge and familiarity with the implementation of a city lockdown. For locations intending to go into lockdown, similar tabletop exercises are an effective verification option.

The Jinchang gold–copper deposit is located in Eastern Heilongjiang Province,Northeastern China. The orebody comprises primarily hydrothermal breccias, quartz veins, anddisseminated ores within granite, diorite, and granodiorite. Three paragenetic stages are identified:early quartz–pyrite–arsenopyrite (Stage 1), quartz–pyrite–chalcopyrite (Stage 2), and latequartz–pyrite–galena–sphalerite (Stage 3). Gold was deposited during all three stages and Stage 1was the major gold-producing stage. Copper is associated with the mineralization but has loweconomic value. Fluid inclusions (FIs) within the deposit are liquid-rich aqueous, vapor-rich aqueous,and daughter-mineral-bearing types. Microthermometric data for the FIs reveal decreasinghomogenization temperatures (Th) and salinities of the ore-forming fluids over time. The Th forStages 1–3 of the mineralization are 421–479, 363–408, and 296–347 °C, respectively. Stage 1 fluidsin vapor-rich and daughter-mineral-bearing inclusions have salinities of 5.7–8.7 and 49.8–54.4 wt%NaCl equivalent, respectively. Stage 2 fluids in vapor-rich, liquid-rich, and daughter-mineral-bearinginclusions have salinities of 1.2–5.4, 9.5–16.0, and 43.3–48.3 wt% NaCl, respectively. Stage 3 fluids inliquid-rich and daughter-mineral-bearing inclusions have salinities of 7.9–12.6 and 38.3–42.0 wt% NaClequivalent, respectively. The estimated trapping pressures are 160–220 bar, corresponding toan entrapment depth of 1.6–1.2 km in the paleo-water table. Oxygen and hydrogen isotope data(δ18OV-SMOW = 8.6‰ to 11.4‰; δDV-SMOW = −92.2‰ to −72.1‰) suggest that the ore-forming fluidswere derived from magmatic fluids during the early stages of mineralization and subsequentlyincorporated meteoric water during the late stages. The sulfide minerals have δ34SVCDT values of0.2‰–3.5‰, suggesting that the sulfur has a magmatic origin. The Jinchang deposit is a typicalgold-rich gold–copper porphyry deposit.

Lunula is the white, half-moon shaped area seen in proximal ends of some nails. Though a few studies have described the nail changes that can occur in association with HIV infection, none of these paid much attention to lunula. Aims and Objectives. To study the lunula in fingernails among HIV infected patients. Materials and Methods. An observational, cross-sectional study to record presence of lunula in 168 HIV-positive patients and compare it with age and sex matched 168 healthy HIV-negative control. Anolunula (absence of lunula) in HIV-positive patients was correlated with CD4 counts, stages of HIV infection, time since patient was diagnosed as HIV-positive, and status of antiretroviral therapy. Results. Anolunula was present in significantly more fingernails in HIV-positive patients compared to HIV-negative controls. There was a highly significant difference for total anolunula (anolunula in all fingernails) in study and control group. Incidence of total anolunula was directly proportional to the stage of HIV infection, increasing progressively as the HIV infection advances from stage 1 to stage 4. Conclusion. Absence of lunula is related to not only HIV infection per se but also the stages of HIV infection.

This paper presents the design and implementation of control strategy for both the speed and direction of a direct current (DC) motor using Android-based application in smart phone. The Raspberry Pi 3 with a motor driver controller has been used to implement the control action via Python-based user-defined programming. The Android application has been developed using Android Developer Tools (ADT) in Java platform. The Android apps work like a client and communicates with Raspberry Pi through wi-fi connectivity. Finally, a small graphical user interface (GUI) has been created in Python in order to interface and control the motor with buttons in GUI. The advantages of GUI are that it is attractive, user friendly, and even a layman can work with the application developed in GUI.

The Groupe Bogolan Kasobané is an association of six artists from Mali, West Africa: Kandioura Coulibaly, Klètigui Dembélé, Boubacar Doumbia, Souleymane Goro, Baba Fallo Keita, and Néné Thiam. The five men and one woman began working together in 1978. The Groupe is largely responsible for having elevated bogolan, a Malian textile technique traditionally used to decorate garments, to an important symbol of national and even pan-African identity. The members of the Groupe met as students at the Institut National des Arts (L’INA) in Bamako. At that time, bogolan was rarely seen in urban areas and was fabricated only by rural women. The study of bogolan was also strictly forbidden at the art academy. The Groupe’s use of local materials and elevation of materials associated with craft is a strategy employed by many contemporary artists throughout the world. Their first objective, to promote and preserve bogolan and to have it accepted and valued as artistic expression has been achieved. The Groupe moved the technique from craftsmanship to art. Today the Groupe is known because of their numerous exhibitions in Mali and around the world. Working collaboratively and developing new approaches to this centuries-old technique, they have continued to feature it in their art and award-winning costume and set designs for film and stage as well as fabrics for fashion and home furnishings.
