BACKGROUND AND OBJECTIVES:
Heterogeneity in risk among low-income families suggests the need for tiered interventions to prevent disparities in school readiness. Smart Beginnings (SB) integrates two interventions: Video Interaction Project (VIP) (birth to 3 years), delivered universally to low-income families in pediatric primary care, and Family Check-Up (6 months to 3 years), targeted home visiting for families with additional family risks. Our objective was to assess initial SB impacts on parent-child activities and interactions at 6 months, reflecting early VIP exposure.

METHODS:
Two-site randomized controlled trial in New York City (84% Latinx) and Pittsburgh (81% Black), with postpartum enrollment and random assignment to treatment (SB) or control. At 6 months, we assessed parent-child interactions through surveys (StimQ, Parenting Your Baby) and observation (video-recorded play, coded by using Parent-Child Interaction Rating Scales – Infant Adaptation).

RESULTS:
A total of 403 families were enrolled at child’s birth (201 treatment) with 362 (89.8%) assessed at 6 months. Treatment families had increased StimQ, including total score (Cohen’s d = 0.28; P &lt; .001) and domains reflecting reading (d = 0.23; P = .02) and teaching (d = 0.25; P = .01), and Parent-Child Interaction Rating Scales – Infant Adaptation, including a cognitive stimulation factor (d = 0.40; P &lt; .001) and domains reflecting support for cognitive development (d = 0.36; P &lt; .001), and language quantity (0.40; P &lt; .001) and quality (d = 0.37; P &lt; .001). Thus, significant effects emerged across a broad sample by using varied methodologies.

CONCLUSIONS:
Findings replicate and extend previous VIP findings across samples and assessment methodologies. Examining subsequent assessments will determine impacts and feasibility of the full SB model, including potential additive impacts of Family Check-Up for families at elevated risk.

Abstract
The analysis of individual micrometre- and submicrometre-sized particles collected by IAEA’s safeguards inspectors on swipe samples during in-field verification activities requires the implementation of a sustainable quality control system such as suitable microparticulate reference materials. To this end, pure and neodymium-doped uranium oxide-based microparticles utilising an aerosol-based particle production process were prepared. SEM/EDX measurements confirmed the monodispersity of the produced microspheres as well as the incorporation of 15 mol% Nd into the compound particles. The timeline of structural investigations mirror the ongoing alteration of particles being stored under laboratory atmosphere. While results from in-SEM Raman (CEA, DAM) on microparticles after two years storage time point to the formation of U3O8 and a minor fraction of schoepite phase (hydrated UO3), in U L3-edge XAFS after four months storage time and U M4-edge HR-XANES after ten months storage time spectra (INE-Beamline and ACT station @ KIT synchrotron radiation source) mainly U(IV) and U(V), respectively, was observed. These results provide new insight into ageing mechanism of the microparticles after preparation. From these results important conclusions with respect to storage conditions and shelf life of the reference particles can be drawn. The first batch of pure U-oxide microparticles produced in Juelich was successfully certified regarding the isotopic composition and the U amount per particle and applied in an international laboratory exercise NUSIMEP-9.

Мета: розробка нового алгоритму оптимізації завантаження з метою вирішення проблеми оптимального завантаження повітряних кораблів із подальшим впровадженням алгоритму у новітню модель оптимізації. Методи: евристика, формалізація, комп’ютерне моделювання. Результати: був розроблений новий алгоритм оптимізації, який передбачає розташування груп контейнерів, мінімізуючи час завантаження. Обговорення: Більшість вивчених наукових праць містять різноманітні характеристики вирішення проблеми пакування, оптимізаційні моделі рюкзака, а також виділяють термін «завантаження повітряних кораблів» як проблему вибору контейнерів, пакування та завантаження у вантажний відсік повітряного корабля. Такі моделі сконцентровані на окремих аспектах, в той час як, у реальному часі, проблема оптимізації тісно пов’язана із здійсненням хендлінгових операцій. Вищезазначена новітня модель оптимізації завантаження передбачає декомпозицію проблеми завантаження та впровадження нового пріоритетного алгоритму його планування. Даний алгоритм відноситься до механізму попереднього розташування засобів пакетування у вантажному відсіку повітряного корабля заздалегідь, у пріоритетному порядку, з метою вивантаження згідно документів, із виключенням перевищень допустимих значень із центрування та завантаження та із зменшенням часу завантаження та послідовним скороченням хендлінгових та операційних витрат.

Мета: представлення результатів оцінювання після впровадження розробленої моделі оптимізації завантаження та аналіз адекватності цієї моделі з метою доведення її ефективності, за допомогою зменшення головного критерію – часу завантаження. Методи: експеримент, евристика, статистика, імітаційне моделювання. Результати: розроблена модель оптимізації завантаження пройшла усі процедури верифікації, а аналіз експериментальних даних підвищив її значущість у процесі авіаційного завантаження. Обговорення: Розглянуто деякі параметричні критерії оцінки адекватності моделей для зазначення, що ефективність моделі оптимізації завантаження не може бути оцінена саме за цими критеріями. Тому, оптимізаційна модель з часовими критеріями має бути проаналізована на предмет адекватності лише за непараметричними критеріями, а саме – за Т– критерієм Вілкоксона. Стаття надає результати аналізу експериментальних даних, що демонструють різницю між параметрами моделі та реальною тривалістю процедури завантаження / розвантаження у реальних умовах. Імітаційна модель підтверджує мінімізацію часу завантаження після імплементації оптимізаційної моделі. Отже, результати верифікації моделі можуть розцінюватися як заключна частина дослідження ефективності впровадження інтегрованої мультикритеріальної моделі оптимізації завантаження повітряних кораблів.
Kinetics of Wet In-Situ Combustion: A Review of Kinetic Models
Authors: Cavanzo E. A. , Muñoz S. F. , Ordoñez A.. , Bottia H.. 
Published: February 2021

Abstract
In Situ Combustion is an enhanced oil recovery method which consists on injecting air to the reservoir, generating a series of oxidation reactions at different temperature ranges by chemical interaction between oil and oxygen, the high temperature oxidation reactions are highly exothermic; the oxygen reacts with a coke like material formed by thermal cracking, they are responsible of generating the heat necessary to sustain and propagate the combustion front, sweeping the heavy oil and upgrading it due to the high temperatures. Wet in situ combustion is variant of the process, in which water is injected simultaneously or alternated with air, taking advantage of its high heat capacity, so the steam can transport heat more efficiently forward the combustion front due to the latent heat of vaporization.
A representative model of the in situ combustion process is constituted by a static model, a dynamic model and a kinetic model. The kinetic model represents the oxidative behavior and the compositional changes of the crude oil; it is integrated by the most representative reactions of the process and the corresponding kinetic parameters of each reaction. Frequently, the kinetic model for a dry combustion process has Low Temperature Oxidation reactions (LTO), thermal cracking reactions and the combustion reaction. For the case of wet combustion, additional aquathermolysis reactions take place.
This article presents a full review of the kinetic models of the wet in situ combustion process taking into account aquathermolysis reactions. These are hydrogen addition reactions due to the chemical interaction between crude oil and steam. The mechanism begins with desulphurization reactions and subsequent decarboxylation reactions, which are responsible of carbon monoxide production, which reacts with steam producing carbon dioxide and hydrogen; this is the water and gas shift reaction. Finally, during hydrocracking and hydrodesulphurization reactions, hydrogen sulfide is generated and the crude oil is upgraded.
An additional upgrading mechanism during the wet in situ combustion process can be explained by the aquathermolysis theory, also hydrogen sulphide and hydrogen production can be estimated by a suitable kinetic model that takes into account the most representative reactions involved during the combustion process.
Africa Petroleum Fiscal Evolvement and Impacts on Foreign Investment: Illustrations from Nigeria
Authors: Li Huimin 
Published: February 2021

ABSTRACT
With plenty of latest discoveries witnessed from East Africa, the petroleum atlas reshaping is expected where some new faces (e.g. Mozambique, Kenya, Tanzania, etc.) may play emergent roles besides traditional oil countries in Africa. Due to general lack of infrastructure construction and capital investment, it still need some time for large-scale commercial production and the involvement of international oil companies is indispensable in the process.
Dramatic price drop has tremendously stricken both governments and international oil companies (IOC) in oil-producing countries since 2014. The effectiveness in which governments and IOCs adjust to this reality will determine the extent and the pace of future development of these countries’ oil sectors.
Most IOCs were struggling to cut capital expenditure and control operating cost to survive, and how to maintain and attract investment is regarded as huge challenges by many governments in the downward scenario. Apart from resource factors, petroleum fiscal terms are one of the key factors in the investment decision for IOCs. The attractiveness of fiscal contracts has a fundamental effect on profitability of petroleum projects, and thus an important indicator for evaluating investment feasibility in the country. The paper gives an overview on fiscal transformation in most Africa oil countries, some of them were trying to increase government share in oil profits to support social expenditures, and others have provided fiscal incentives to absorb further investment in the oil sector. It shows that fiscal policies in the countries where national economy relies more on oil revenues are less stable during the past decade. Some upstream projects in Nigeria are illustrated to show the impacts of different contract terms on economic benefits. Thus with new government's coming into power, most IOCs are holding back further investment and expecting negotiation with the authorities for confirmation on fiscal terms applied in their assets to avoid potential contractual risks, like PIB, Side letter, etc. The implications regarding petroleum regime are summarized based on the experience from Nigeria for emerging countries in East Africa, relatively stable fiscal policy with some incentives to encourage exploration activities would be helpful to petroleum industry. Lastly, investment suggestions are presented with priorities to promote business development in the area.
Prospects and Challenges of Developing Unconventional Petroleum Resources in the Anambra Inland Basin of Nigeria
Authors: Onuoha K. Mosto , Dim Chidozie I. 
Published: February 2021

ABSTRACT
The boom in the development of unconventional petroleum resources, particularly shale gas in the United States of America during the last decade has had far reaching implications for energy markets across the world and particularly for Nigeria, a country that traditionally has been Africa&rsquo;s leading crude oil producer and exporter. The Cretaceous Anambra Basin is currently the only inland basin in Nigeria where the existence of commercial quantities of oil and gas has been proven (outside the Tertiary Niger Delta Basin). The possibility of similarly finding commercially viable resources of unconventional petroleum resources in the basin appears quite attractive on the basis of the existence of seepages of shale oil and presence of coal-bed methane in some of the coal seams of the Mamu Formation (Lower Coal Measures) in the basin. This paper presents the results of our preliminary assessment of the shale oil and gas resources of the Anambra Basin. Our main objective is to locate the zones of very high quality plays within the basin, focusing on their depositional environments (whether marine or non-marine), areal extent of the target shale formations, gross shale intervals, total organic content, and thermal maturity. Data on the total organic content (TOC %, by weight) and thermal maturity of shales from different wells in the basin show that many of the shales have high TOCs (i.e greater than 2%) comparable to known shale gas and shale oil plays globally. Shale oil seepages are known to occur around Lokpanta in south-eastern Nigeria, but there is a general predominance of gas-prone facies in our inland basins indicating good prospects for finding unconventional petroleum in this and other Nigerian inland sedimentary basins. The main challenge to the exploration of unconventional resources in Nigeria today has to do with the absence of the enabling laws and regulatory framework governing their exploration and subsequent exploitation. The revised Petroleum Industry Bill (PIB) currently under consideration in the National Assembly is expected to introduce drastic and lasting changes in the way the petroleum industry business is conducted in the country, but all the provisions of the draft law pertain mainly to conventional oil and gas resources.

ABSTRACT
Fula field at Block 6, Sudan contains crude of 16.8 to 19 °API with in-situ viscosity of 497 cp in Bentiu formation. It was on production in March, 2004 and has produced 14% of original oil in place. Massive and unconsolidated sandstones inter-bedded with thin (3 to 13 ft) and discontinuous shales possess high horizontal and vertical permeabilities (2 to 9.53 Darcies). Lateral dimensions of shale bodies range from 1,000 to 2,000 ft. To extend oil production life with water-free, initial development strategy was to perforate the upper and more permeable zones (Perforations are 30% of entire zones) to obtain profitable productivity. After fieldwide water breakthrough, based on the studies of bypassed oil distribution, the following innovative deeper re-completions have been applied in high-water-cut wells (water cut more than 80%) to exploit the bypassed oil zones and new pay zones that have been missed below the existing productive zones. squeeze cement into the existing high-water-cut zones, located at the upper portion of entire pay zones. Those long wormholes communicating with aquifer caused by deep sanding should be cemented.perforate partially the lower portion of pay zones with optimal shot density. 30 to 40% of entire pay zones and shot density of 5 shots per foot are recommended. Perforation tunnel optimization can be run for concrete well conditions.Progressing Cavity Pumps operate at low frequencies less than 30 Hz to regulate proper pressure drawdown less than observed critical value of sanding from field tests and water coning.
Field production data indicate that this workover campaign has achieved more than 2-fold oil gain and reducing water cut by 30 to 50% compared to previous water cuts of over 80%, also, water cut plus dynamic fluid level remain relatively stable over 6 months.
A novel transcription factor PunR and Nac are involved in purine and purine nucleoside transporter punC regulation in E. coli

Published: February 2021

Abstract
Many genes in bacterial genomes are of unknown function, often referred to as y-genes. Recently, novel analytic methods have divided bacterial transcriptomes into independently modulated sets of genes (iModulons). Functionally annotated iModulons that contain y-genes lead to testable hypotheses to elucidate y-gene function. Inversely correlated expression of a putative transporter gene, ydhC, relative to purine biosynthetic genes, has led to the hypothesis that it encodes a purine-related transporter and revealed a LysR-family regulator, YdhB, with a predicted 23-bp palindromic binding motif. RNA-Seq analysis of a ydhB knockout mutant confirmed the YdhB-dependent activation of ydhC in the presence of adenosine. The deletion of either the ydhC or the ydhB gene led to a substantially decreased growth rate for E. coli in minimal medium with adenosine as the nitrogen source, as well as with inosine or guanosine. Taken together, we provide clear evidence that YdhB activates the expression of the ydhC gene that encodes a novel purine transporter in E. coli. We propose that the genes ydhB and ydhC be re-named as punR and punC, respectively.

Published: February 2021

Abstract
Background

As a non-small cell lung cancer, lung adenocarcinoma (LUAD) is common in women and non-smokers. This study is aimed to construct a prognostic score (PS) model for adult females with LUAD.
Methods

The gene expression data of adult females with LUAD from The Cancer Genome Atlas database was obtained as the training set, and GSE50081 and GSE37745 from Gene Expression Omnibus database were downloaded as the validation sets. The differentially expressed genes (DEGs) between LUAD and normal samples were screened by limma package. The metabolism-associated DEGs were selected by Gene Set Enrichment Analysis, and were conducted with enrichment analysis using DAVID tool. After the independent prognosis-associated genes were identified by survival package, the optimal gene combination was screened using penalized package to build the PS model. Besides, the nomogram survival model based on the independent prognostic clinical factors was constructed by rms package. Using HPAanalyze package, the protein expression levels of the optimal genes were mined.
Results

There were 2388 DEGs between LUAD samples and normal samples. Totally, 150 metabolism-associated DEGs were screened, for which PPAR signaling pathway was enriched. The optimal gene combination (involving CYP17A1, ASPG, DUOX1, CIDEC, TH, B4GALNT1, APOA2, and GCKR) was selected, based on which the PS model was built. Combined with pathologic stage and PS model status, the nomogram survival model was constructed. Moreover, CIDEC was a characteristic gene in lung cancer and other cancers.
Conclusion

The PS model and the nomogram survival model might be applied for the prognostic prediction of adult females with LUAD.
A new simplified method for efficient extraction of solar cells and modules parameters from datasheet information
Authors: Muhammadsharif Fahmi F. 
Published: February 2021

Abstract
An accurate and straightforward estimation of solar cells and modules parameters from the manufacturer’s datasheet is essential for the performance assessment, simulation, design, and quality control. In this work, a simple and efficient technique is reported to extract the parameters of solar cells and modules, namely ideality factor (n), series resistance (Rs), shunt resistance (Rsh), photocurrent (Iph) and saturation current (Io), from datasheet information. The method is based on defining the peak position of the function \(f\left(n,{R}_{sh}\right)=n\left({R}_{sh\_max}-{R}_{sh}\right)\), at which the five parameters are extracted. It was validated on four different technologies of solar cells and modules, including Poly-Si, Mono-Si, thin film and multijunction. Results showed that a simple and efficient extraction of the parameters can be realized by using this technique compared to that of the reported methods in literature.

Abstract
Background
Concurrent chemoradiotherapy (CCRT) treatment incompletion is a known negative prognosticator for patients with head and neck cancer (HNC). Malnutrition is a common phenomenon which leads to treatment interruption in patients with HNC. We aimed to compare the performance of three nutritional tools in predicting treatment incompletion in patients with HNC undergoing definitive CCRT.
Material and methods
Three nutritional assessment tools, Mini Nutritional Assessment-Short Form (MNA-SF), Malnutritional Universal Screening Tool (MUST), and Nutritional Risk Screening 2002 (NRS-2002), were prospectively assessed prior to CCRT for HNC patients. Patients were stratified into either normal nutrition or malnourished groups using different nutrition tools. Treatment incompletion and treatment-related toxicities associated with CCRT were recorded.
Results
A total of 461 patients were included in the study; malnourished rates ranged from 31.0–51.0%. The CCRT incompletion rates were 4.9–6.3% and 14.5–18.2% for normal nutrition patients and malnourished patients, respectively. The tools had significant correlations with each other (Pearson correlation 0.801–0.837, p < 0.001 for all) and accurately predicted the incompletion of CCRT. MNA-SF had the highest performance in predicting treatment-related toxicity, including emergency room visits, need for hospitalization, any grade III or higher hematological adverse events, and critical body weight loss, compared to the other tools.
Conclusions
MNA-SF, MUST, and NRS2002 were all shown to be competent tools for malnutrition recognition and prediction of treatment incompletion, as well as treatment-related toxicity, in HNC patients undergoing CCRT. We suggest implementing nutritional assessment prior to treatment to improve the rate of treatment completion and to reduce treatment-related toxicity in HNC patients.
