Computer Science and Mathematics Intervention: Addressing Underprivileged Student Engagement and Equity Gaps in Computer Science
Authors:   , Sandler Kristen
Published: May 2022

This study examined a middle school mathematics intervention course titled programming robotics, and mathematics (PRM). The course teaches mathematics through computer science and robotics concepts. The study assessed the relationship between the course and mathematics achievement as well as student interest level in future computer science coursework and career after completing the course. To analyze mathematics achievement, an independent t-test was used to compare the means on a mathematics assessment of the control group of 4,801 students and the PRM group of 381 students. To analyze future interest in computer science courses and careers, PRM students completed a survey and descriptive statistics were used to analyze the results. While the mathematics achievement data were determined to be statistically insignificant based on the survey results, the PRM course created student interest in future computer science coursework and careers. This study took place during the 2020–2021 school year, while students were on distance learning due to the COVID-19 pandemic. Recommendations are to revisit this study during a more traditional school year.
YIELD AND PHYTOSANITARY STATE OF THE LAST CROPS OF THE CROP ROTATION OF WHEAT AND BARLEY
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, PEGOVA N.A.
Published: May 2022

The article shows the analysis of the effect of long-term application (since 2006) of nonmoldboard and combined systems of main tillage in a crop rotation in comparison with annual moldboard tillage on productivity of spring wheat, yield and phytosanitary state of barley. The author studied tillage options in a cereal-grass rotation (71% cereals) with different types of fallow (clean, manured, clover and mustard) and with winter rye straw left in the field. Annual mouldboard tillage resulted in the highest yields of spring wheat and barley in the experiment – 2.90 and 2.31 t/ha. Annual nonmoldboard tillage resulted in a significant reduction in wheat yield to 2.61 t/ha and barley yield to 1.28 t/ha. The combined tillage system, alternating two mouldboard and four nonmoldboard treatments per rotation, ensured the wheat yield at the level of the mouldboard system – 2.82 t/ha, and a decrease in barley yields to 1.85 t/ha. In 2020, the limiting factor for barley yield formation in the variants with surface distribution of crop residues and straw was increased weed infestation and deterioration of the phytosanitary state of the crop. Straw had a depressive effect on the yield of the last crops in a crop rotation with pure fallow. Crop yields decreased by 0.43 and 0.26 t/ha. Wheat yield was 2.34 t/ha, barley yield was 1.41 t/ha. Green manure mustard and clover fallows leveled the depressive effect of straw. The yields of the 6th and 7th crops of the crop rotation were at the control level (2.69–2.78 t/ha of wheat and 1.70–1.81 t/ha of barley). Regardless of the tillage system and the use of by-products as organic fertilizer, the application of manure ensured the highest yields of the final crops of the rotation: 3.10 and 2.99 t/ha for spring wheat and 2.00 and 2.14 t/ha for barley.

Published: May 2022

This study explores students’ perspectives and experiences on the implementation of a flipped classroom model to develop listening comprehension. Within a qualitative data approach, using an open-ended questionnaire, information was collected from three university students chosen through convenience sampling. The data suggest that the implementation of this model improved students’ learning and motivation. By analyzing their responses using a content analysis method, the benefits perceived by the students who experienced the flipped classroom model were identified and grouped into five themes: Peer learning, Better preparation, Improved understanding, Motivation, and Autonomy. The findings of this study may be relevant not only for students but also for educators who are willing to improve their online teaching.
O oráculo como elo entre a jurisdição e os smart contracts
Authors: Silveira Jan Felipe
Published: May 2022

O artigo tem como elemento central o estudo dos reflexos da adoção de smart contracts nas relações privadas. O trabalho concentra sua abordagem na possibilidade de esvaziamento das formas de jurisdição tradicionais, pela característica da auto executoriedade das cláusulas contratuais, como consequência da utilização da tecnologia blockchain. A tecnologia blockchain vem se tornando um dos maiores protagonistas na transformação das tecnologias digitais e isso se deve a sua peculiar característica de gestão descentralizada das informações, além de sua confiabilidade. A análise parte da identificação dos elementos intrínsecos dos smart contracts, demonstrando, de maneira dedutiva, suas especificidades e seus pontos de intersecção com a teoria contratual tradicional. Com a ampliação da utilização dos smart contracts para regular cada vez mais situações da vida privada, estabeleceu-se a necessidade de incorporar um elemento exógeno ao sistema, que é a figura do oráculo, cuja função é alimentar com dados externos a blockchain. Tem-se, portanto, um elo entre o mundo fenomênico e o mundo puramente virtual, através da tecnologia blockchain. Desse modo, a partir da concepção do oráculo, abre-se a possibilidade de ligação entre a jurisdição e os smart contracts.

Published: May 2022

Peningkatan jumlah produksi alpukat dipengaruhi oleh efektivitas pemupukan. Pemupukan adalah hal terpenting dalam pertanian untuk meningkatkan nutrisi tanaman, mencapai tinggi hasil, dan perubahan lingkungan tanah. Penggunaan pupuk hayati diperlukan untuk meningkatkan kualitas dan kuantitas tanaman serta memperkecil peluang terjadinya degradasi lahan. Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) dengan faktor tunggal berupa pemupukan. RAK ini mempunyai sembilan taraf perlakuan, yaitu: 1) kontrol (tanpa pupuk NPK dan hayati), 2) pupuk NPK 100%, 3) pupuk NPK 50%, 4) pupuk NPK 100% + pupuk hayati 100%, 5) pupuk NPK 100% + pupuk hayati 50%, 6) pupuk NPK 50% + pupuk hayati 100%, 7) pupuk NPK 50% + pupuk hayati 50%, 8) pupuk hayati 100%, 9) pupuk hayati 50%. Perlakuan ini diulang sebanyak lima ulangan. Penggunaan NPK sebagai kombinasi dan substitusi dari pupuk hayati. Pupuk dasar yang digunakan, yaitu pupuk kandang sebanyak 1.25 kg/pohon. Secara keseluruhan perlakuan terbaik adalah kombinasi dari pupuk NPK dan pupuk hayati khususnya pada perlakuan P3, yaitu kombinasi antara NPK 100% dan pupuk hayati 100%. Hal ini terlihat pada pertumbuhan vegetatif tanaman alpukat serta hasil analisis kimia dan biologi tanah yang meningkat. Hasil siginifikan terjadi pada laju tinggi tanaman, jumlah cabang tersier, N-total, dan aktivitas invertase tanah.

Water-stable zeolitic imidazolate frameworks (ZIF) with zinc and cobalt cations were synthesized to explore the effect of metal ions on arsenic adsorption. At room temperature (25 2 ºC) and pH 7.8, maximum adsorption capacities of arsenic (As5+) on the surface of ZIF-8 and ZIF-67 were 87.03 and 86.70 mg g-1 respectively, with encouraging results up to 95% reusability of the adsorbents. The results of this study revealed that electrostatic attraction and ion exchange were the major mechanisms responsible for better efficiencies for adsorptive removal of arsenic. The evidence for the adsorption of arsenic contaminants was confirmed by FTIR analyses. The pseudo second order and Langmuir models were best suited to explain the adsorption of arsenic species on the surface of the as-synthesized metal-organic frameworks (MOFs). Based on the results, it was possible to conclude that the metal atoms in the synthesized MOFs had a minor impact on adsorption, since these MOFs presented identical results in the removal of arsenic species. This observation can be explained by the presence of a similar organic linker (2-methyl imidazole), which points to almost the same geometry and sponginess. However, there was a slight difference in the adamsite (organo-arsenic) removal achieved by the MOFs with different metal atoms.

The method of universal arc characteristics developed for calculating the electrical and thermal characteristics of the cylindrical part of the Mecker model column allows simple algebraic methods to calculate the characteristics of the arc column at a distance from the cathode and, thereby, to concretize the mathematical model of Mecker. The proven conservativeness of the arc as a result of the formation of a spatial layer with increased volumetric viscosity on the surface of the column allows, in accordance with the provisions of the boundary layer theory, to apply a boundary condition of the third kind to the surface of the cylindrical part of the arc column. The method of universal arc characteristics also helps to link the boundary value of the linear heat flux density on the surface of the cylindrical part of the column with the temperature profile of the column and, thereby, to specify the dependence of the electrical, geometric and thermal characteristics of the column plasma on the conditions of arc heat exchange in the working space of the installation with electric arc heating. The proposed method makes it possible, based only on the external voltage characteristics of the arc, to identify the Mecker heat exchange model and calculate by a simple algebraic method the structure and values of the heat fluxes generated by the arc during heat exchange with the plasma torch gas jet in the melting space of the plasma arc furnace. Examples of arc characteristics are given when working on different gases for different stages of melting — at the beginning of melting and during the melting of the charge.

Authors: Huang Ya-Lan , Chin Erh-Tsung
Published: May 2022

Teacher’s Professional Learning Community (PLC) should effectively operate through sharing teaching resources, professional dialogues, and collaboration to reduce pupil’s learning achievement gaps and make teaching close to their learning experiences through providing learning scaffolding. This study adopts a qualitative research method to investigate the change of participants’ Mathematics Knowledge for Teaching (MKT) of a primary school teacher PLC which has been running for three years. The three research subjects are experienced teachers and none of whom are mathematics or science majors. According to the framework of the MKT (Hill et al. 2008), the qualitative data which include PLC meeting videos, lesson observation sheets, interviews, and learning feedback are analyzed and triangulated by the researchers and other mathematics educators. The results show that PLC may help teachers improve their MKT. At the beginning of the PLC, the discourse was mainly related to the teacher’s Knowledge of Special Content Knowledge (SCK) and Knowledge of Content and Teaching (KCT). It reveals that the participants ought to be energized in SCK and KCT, and the PLC activities should be specially arranged in these two aspects. After the continuous professional dialogue and teaching practices, the teacher’s KCC, Knowledge of Content and Student (KCS), and Special Content Knowledge (SCK) are improved most significantly, which also promotes the student learning achievements.

Published: May 2022

Soil contamination as a result of human interferences with nature is a common occurrence all over the world. Soil samples were collected from three universities (Ignatius Ajuru University of Education (IAUE), University of Port Harcourt (UNIPORT) and the Rivers State University (RSU) in Port Harcourt, Rivers State. The soils were taken at the points where the different institutions generate electricity with diesel powered generators. The soil samples were collected from the surface to a dept of 30 cm and were put into tightly closed glass containers. They were transported to the laboratory and prepared by standard methods of extraction and purification. The extracts were analyzed with a gas chromatography – mass spectrophotometry instrument to obtain the various fractions of PAHs present in the samples. It was observed that all the 16 priorities PAHs were present in all the samples from the station. The total concentrations of PAHs showed that IAUE>UNIPORT>RSU with respective values of 18.18, 16.64 and 16.53 mg/Kg. Benz(a)anthracene was observed to be the most abundant PAH in all the stations with a value of 2.11±0.14, 2.01±0.51 and 2.10±0.57 mg/Kg for IAUE4>5>6 rings. The concentrations of carcinogenic and non-carcinogenic PAHs were almost in equal proportions in the soils examined. Therefore, the workers involved directly with the electrical generation on these campuses should adequately protected and informed on the consequences of contact with the soil and the gases that come out of the exhaust.

Published: May 2022

Background: Nutritional intake in children plays an important role in optimizing growth and development in children. The adequacy of nutritional intake in children can be assessed by the state of nutritional status characterized by thin, normal, and obese children. One of the roles of parents is to be responsible for fulfilling nutrition for their children. The desire of parents to fulfill their children's nutritional needs is often the background of inappropriate feeding practices. Inappropriate feeding practices include always fulfilling a child's desire to consume the food he wants, even many parents allow whatever food their child consumes, many parents serve ready-to-eat food Lack of nutritious food will lead to child growth retardation, the prevalence of malnutrition in 2013 was 19.6%, consisting of 5.7% malnutrition and 13.9% malnutrition. When compared with the national prevalence rate in 2010 (17.9%), it seems that this is increasing.
Purpose: The aim of this study is to know the relationship between the role of parents in preparing a balanced menu with the nutritional status of children.
Methods: The design used is a literature review, namely by using several journals from several sources such as: Google Scholar, PubMed. Nutritional Status, publication year between 2015-2020.
Results: The results of the journal discussion show that there is an influence between the role of parents in preparing a balanced menu for children with the nutritional status of the child. Conclusion: It was concluded that the role of parents is really needed for the growth and development of the child.

常规的水平轴风力发电机利用风速的范围大约在3~25米。但是中国（我国）大陆东南区域陆地上风速往往比较低；同时沿海会出现台风等自然灾害。拓宽中国东南地区风速利用的范围，对于充分利用作为可再生无碳绿色替代能源的风能有积极地意义。根据“刚体定轴转动定律”可知：降低风轮的机械转动惯量对于所有类型的风机都有好处，一种具体的措施是缩短叶片对旋转中心的几何长度。低风速风机应增大叶片的面积。大风风机应降低叶片的面积，提高叶片的机械强度。由于台风或大风时间较短，台风发电应该配合抽水蓄能。并探索利用“风暴潮、巨浪、潮汐”自动蓄水的可能性。
A single nucleotide variant on chromosome 16 residing within DPEP2 distinguishes patients with luminal A breast cancer.
Authors: Mamoor Shahan
Published: May 2022

Molecular subtypes including the most common subtype luminal A drive patient outcomes in human breast cancer but the biological basis for this is not completely understood (1-4). We mined published microarray data (5, 6) to discover in an unbiased fashion the most distinguishing genetic and transcriptional features of tumors of each breast cancer molecular subtype. We identified a single nucleotide polymorphism, rs255052, residing within DPEP2, as among the most significant genetic differences in the tumors of patients with luminal A breast cancer. In a separate cohort of patients with luminal A subtype breast cancer, we observed transcriptome-wide differential expression of a DPEP2 transcript. Analysis of patient survival data revealed that DPEP2 primary tumor expression was correlated with overall survival in patients with basal-like and luminal A breast cancer. Sequence variation in the DPEP2 gene may be important in understanding differences in genetic background that favor development of luminal A subtype human breast cancer.
Turkey's Interests And Constructive Eurasianism
Authors: Tulun Teoman Ertuğrul , Tulun Mehmet Oğuzhan
Published: May 2022

Western countries and Russia are locked into an ideological conflict and dangerous brinkmanship over the future of Ukraine, NATO-member and EU-candidate Turkey has drawn attention due to its efforts to maintain a delicate balance in its relations with its Western allies, Russia, and Ukraine. Such a stance has highlighted Turkey's foreign policy and its place in its region and, in fact, the world. Antiquated Cold War-era mindsets view Turkey as a mere frontline asset of the Western world and that Turkey's deviation from such a role is inherently threatening for the West. Turkey's best interest lays in adopting Constructive Eurasianism that on the one hand values Turkey's institutionalized connections with the West, and on the other hand looks into the potential offered by increased ties with Turkey's east. Constructive Eurasianism values and respects Turkey's NATO membership and supports its EU candidacy, even though the latter promises the Turkish people an improbable future. However, it also recognizes that some of the florid language employed by Western countries with emphasis on democracy, pluralism, the rule of law, and the "value-based relationship" rhetoric masks centuries-old imperialistic ambitions and an arrogant attempt to intervene in the domestic politics of other countries. Considering all these issues, Constructive Eurasianism, unlike other forms of Eurasianism advocated, "will benefit Turkey because it rejects creating new rivalries and antagonisms, and instead seeks to create new avenues for cooperation so that Turkey can position itself properly in a changing world." As such, Constructive Eurasianism will allow Turkey to continue to be an integrated part of the West and at the same time to function as a true nexus between the West and the East.

Menurut Berger pemikiran sosiologi berkembang manakala masyarakat menghadapi ancaman terhadap hal yang selama ini dianggap sebagai hal yang memang sudah seharusnya demikian, sekarang banyak kebiasaan yang sudah menjadi ancaman, beraktivitas di luar rumah misalnya. Dunia sekarang sedang memasuki masa dimana terdapat suatu penyakit yang telah ditetapkan oleh WHO sebagai pandemi dunia yaitu virus corona atau covid-19. Melalui Direktur Jenderal Organisasi Kesehatan Dunia (WHO) Tedros Adhanom Ghebreyesus secara resmi mengumumkan virus Corona (covid-19) sebagai pandemi pada tanggal 11 Maret 2020 yang lalu. Hal ini menandakan bahwa Corona (covid-19) telah menjadi salah satu penyakit yang berbahaya karena cepat menyebar dari manusia ke manusia, yang pada saat ini telah tersebar hampir di seluruh belahan dunia. Tedros pun meminta agar setiap pemerintahan negara membuat suatu kebijakan yang mendesak dan agresif atas respon terhadap Corona (covid-19) ini. Kemudian respon dari pada pemerintah Indonesia, berdasarkan arahan dari Presiden Jokowi pada tanggal 15 Maret 2020 yang lalu , mengajak agar masyarakat Indonesia untuk menerapkan social distancing. Sektor perekonomian menjadi salah satu yang paling berdampak akibat pandemi covid-19 ini, terkhusus dalam pembahasan dalam makalah ini yakni industri otomotif. GAIKINDO (Gabungan Industri Kendaraan Bermotor Indonesia salah satu yang paling getol menyuarakan hal ini. Di Indonesia sendiri sudah ada bebrapa industri otomotif yang menghentikan produksinya untuk semetara akibat turun drastisnya permintaan akan produk mereka. Adapun beberapa industri dimaksud adalah Daihatsu, Toyota, Honda dan Suzuki.Kejadian tersebut menegaskan bahwasanya dunia industri otomotif tidak dalam keadaan yang baik, bahkan berada pada titik lemah, industri otomotif terkena pukulan telak pada masa pandemi covid-19 ini. GAIKINDO memaparkan data penjualan, pada bulan januari tahun ini penjualan retail masih mencapai 81.063 unit, februari turun menjadi 77.847, maret 60.448 unit dan data terakhir yang didapat yakni pada bulan april mengalami anjlok tajam pada jumlah 24.276 unit saja. Karena dampak tersebut GAIKINDO mengusulkan beberapa kebijakan kepada pemerintah demi terjaganya stabilitas industri otomotif di Indonesia. Beberapa kebijakan yang didukung adalah mengenai relaksasi pajak PPnBM dan BBNKB sampai bulan desember 2020 yang dianjurkan oleh kementerian Perindustrian. Oleh karena itu, penulis tertarik untuk membahas salah satu bagian sektor perekonomian yang terkena dampak begitu besar, karena bagian ini akan menggambarkan sektor perekonomian lainnya, jangan sampai Indonesia terjebak dalam transisi permanen, sebagaimana terjadi di sejumlah negara yang mengalami failed state (negara gagal).

It’s Time to Replace the Personality Disorders with the Interpersonal Disorders
Authors: Wright Aidan G.C. , Ringwald Whitney R. , Hopwood Christopher James , Pincus Aaron L.
Published: May 2022

Personality disorders are among the most common and severe classes of psychopathology. From a clinical perspective, it is challenging to help individuals with personality disorders because treatment ruptures, discontinuation, reversals, and failures are relatively common. An additional clinical challenge is that the model used to diagnose personality disorders is demonstrably incorrect. Recent efforts to improve diagnosis of personality disorders apply two criteria: the first distinguishes personality disorders from other kinds of psychopathology, and the second distinguishes different types of personality disorder. However, this approach has been problematic, in that as currently operationalized it does not provide a clear demarcation for personality disorders, and it uses a framework for individual differences that is more apt as a model of variation in psychopathology in general. This paper proposes that the core of personality disorders involves difficulties understanding and relating to self and others, and thus the personality disorders should be recast as the interpersonal disorders. Interpersonal dysfunction explains extreme social challenges and treatment difficulties that are characteristic of this class of psychopathology. This approach provides a clearer model for distinguishing these kinds of problems, as demonstrated by reformulating traditional personality disorder symptoms from an interpersonal perspective.
"It's NOT talked about" Mental Health in Rural Communities
Authors: Janney Carol A
Published: May 2022

In rural areas, individuals with mental illness have limited, if any, access to evidence-based, effective, and affordable mental health care. Patient education to support self-management of mental illness may not be available or readily accessible. Hence, this pre-engagement proposal aims to develop a mental health patient-centered research community and advisory board for XXXX and the surrounding rural communities with the long-term goal of improving mental health care, self-management, and outcomes. Both the mental health patient-centered research community and advisory board are new concepts and collaborations for XXX and the surrounding rural communities. First, the project will focus on identifying mental health and community stakeholders, including but not limited to the following: individuals and families with mental illness; providers of mental health services and primary care; mental health organizations; civic and faith based organizations; schools and colleges; industry; and local Health Departments. Next, individual or group meetings will be held with the mental health and community stakeholders to identify 1) mental health resources currently available in these rural communities, 2) unmet behavioral and mental health needs of the rural residents, 3) priority issues, and 4) volunteers interested in serving on the advisory board and/or participating in the mental health patient-centered research community. Finally, an advisory board will be established to create a research agenda for patient-centered outcomes and comparative effectiveness research (PCOR/CER) that is meaningful for these patients and rural communities and has the potential to significantly improve mental health care, self-management and/or outcomes in these rural communities.
How relevant is NIMBYism in public goods provision? Experimental insights from 5G antenna placement in Switzerland
Authors: Rudolph Lukas , Quoß Franziska , Bernauer Thomas
Published: May 2022

When supplying public goods to society at large depends on provision from specific sites, such supply can be hampered by localized ``not-in-my-backyard'' (NIMBY) opposition at provision sites. Examples include opposition to waste management facilities, wind turbines, transport infrastructure, mobile antennas, or social housing. Estimating the level of NIMBY opposition faces two difficulties, however, which are insufficiently addressed in the current literature. First, provision site selection can be endogenous to localized public support or opposition. Second, opposition to a particular public good in society more broadly and NIMBY-related local opposition can be intertwined but need to be analytically separated. We use a novel experimental study design to deal with these two challenges, focusing on public attitudes and political behavior towards 5G antenna placement in Switzerland (N=5’000). This allows us to causally identify how relevant NIMBY effects are to mass public support for public goods provision in this case. When randomly revealing real-world antenna locations to respondents, we find that NIMBYism does affect the formation of attitudes and policy preferences towards 5G expansion. Against our expectations, this is particularly the case among respondents ex-ante in support of public good provision. It also affects the (stated) propensity to engage in political action against 5G antennas, irrespective of monetary costs.

Communication of heatwave risks is an important part of effective adaptation, with news media images playing an important role in the framing process. We examined visual news coverage of the 2019 heatwaves in France, Germany, the Netherlands and UK, using content and visual critical discourse analyses. Many visuals were positively valenced (in contrast to article texts), framing heatwaves as ‘fun in the sun’. The most prevalent type of images in all countries were photographs of people having fun in or by water. When images did depict the danger of heat extremes, people were largely absent. We conclude that this visual framing of heatwaves is problematic: first, by displacing concerns of vulnerability, it marginalises the experiences of those vulnerable to heatwaves; and second, it excludes opportunities for imagining a more resilient future. We conclude with suggestions to diversify the visual discourse on climate change and heatwaves in the news media.

This study investigated the metabolized energy values of succulent leaf of Vernoma amygdalina (Bitter leaf meal) mixed with Musa sapientum leaf (Banana leaf meal) (BBLM) on performance of growing pigs. The experiment was conducted at the Swine Unit of the Teaching and Research Farm, University of Uyo, Uyo, Akwa Ibom State, Nigeria. A total of 40 large white breeds of pigs (growers) were used for the study. The pigs were divided into 5 groups based on average initial weights (20 to 25 kg) and each group of grower pigs were respectively allotted to each of the five treatment diets using a completely randomized design (CRD). Each treatment group contained 2 replicates of 4 pigs (2 males and 2 females). These pigs were fed twice daily and water supplied was given ad libitum. The treatment diets consisted of BBLM at 0 (control), 20, 40, 60 and 80%. The 50:50 ratios of banana leaf and bitter leaf meal were derived by equal weighing (kg) of the two test ingredients percentage in the diet using a manual scale. All diets were formulated to be iso-nitrogenous and iso-caloric. During the feeding trial, daily feed consumption, metabolized energy values, weight changes, and nutrient digestibility were determined and recorded for all the levels, while weight gain, feed conversion ratio and protein efficiency ratio were estimated to assess performance of the weaner pigs. The results revealed that metabolized energy values of BBLM as shown in T1, T2, T3, T4 and T5 obtained in this study were significantly (p<0.05) increased in each of the diets. The reason for the significant increase was as a result of the presence of banana leaf meal in the feed formulation due to its high fibre content. The results from the study also showed significant (p<0.05) differences on the performance characteristics of grower pigs. It was found that animals on 80% diet gave the best performance compared to other diets in final weight gain, feed conversion ratio and protein efficiency ratio (25.67 kg, 2.06 and 2.52) respectively. There were significant differences (p<0.05) on the nutrient digestibility of the pigs. It was concluded that the metabolized energy values of BBLM increases as the level of inclusion were higher and as such can completely replace maize as a source of energy without adversely affecting the overall growth performance of the pigs.

This study was carried out to evaluate the nutritional composition and acceptability of powdered ogi enriched with date palm fruits. Ogi is a fermented slurry made with maize. Ogi enriched with date palm fruits was formulated in order to develop a nutrient dense product and an alternative to the available products, by increasing the usage of these crop materials. The prepared powdered ogi (POD) was enriched with the inclusion of different proportions of powdered dates (0, 5, 10 and 15%, which were labeled control, POD1, POD2 and POD3 respectively). Proximate analysis and sensory evaluation were then carried out on the samples. The results showed that there was a significant difference (p< 0.05) in the proximate composition of the enriched ogi samples, with sample POD3 having relatively higher values for ash (12.07%) and crude fibre (3.51%) when compared to the control. From the result of the mineral analysis, the concentration of minerals (Na, K, Fe, and P) increased significantly (p<0.05) with increasing level of dates, with POD3 having the highest concentration of P (768.16 ppm), K (728.00 ppm) and Fe (127.00 ppm). POD2 had a significantly high (p<0.05) concentration of Na (146.00 ppm). The sensory properties of the samples were generally liked by the panelist, but the overall acceptability of POD3 was highly rated and preferred. This study revealed that the enriched samples were nutrient dense and therefore recommended for homes to alleviate hidden hunger.
Some aspects of carbon sequestration capacity of arable soils

The article analyzes the possibilities of arable soils for atmospheric CO2 sequestration by using modern agricultural technologies. Such possibilities are concluded to be very limited, as they increase the content of organic matter (OM) in the topsoil up to 0.1% С use until an OM equilibrium level is reached. For chernozems (Phaeozems) in the forest-steppe region this value accounts for not more than 10% of the soil organic carbon, lost since the soils started to be used for agricultural production till they reached equilibrium in carbon content. The reasons for the poor atmospheric carbon sequestration capacity of agricultural soils are explained, firstly, by a sharp, three-fold or more, decrease in the plant residues input to soils in comparison with undisturbed soils and, secondly, by the inability to firmly fix freshly formed humus substances: firm fixation of humus substances makes them inaccessible to soil microorganisms. It was shown that with the annual application of 14C labeled plant residues, soil carbon content stopped increasing already by the fifth year of the experiment, which indicated the establishment of a balance between carbon mineralization and fixation of 14C labeled compounds in soil. A preliminary conclusion was made that the ability to firmly fix freshly formed humus substances is an exclusive feature of undisturbed or abandoned arable soils. Arable land can play a significant role in atmospheric carbon sequestration only if abandoned after use. Such approach can be employed to a very limited extent on the lands that are not suitable any more for agricultural production.
