Poetic “being-with”: A Case for Relational Poetics
Authors: Ogle Nat 
Published: March 2021

Abstract
This article repurposes the conceptual ingredients of participatory art, from 1960s Environment-Happenings to 1990s and contemporary relational aesthetics, to postulate an analogous poetics. While both epochs of interactive art exercise the same premise—that is, taking “the sphere of human relations as site for the artwork” to “induce models of sociability,” as Nicolas Bourriaud claims—the conditions of relationality entailed in each concern distinct modes of production, consumption, and governance. I trace this distinction in relation to the Foucauldian notion of “technologies of power,” arguing that, while Allan Kaprow's practice engages with the biopolitical, “disciplinary” power of liberalist regimes, the work of Félix González-Torres and Rirkrit Tiravanija engage with what Byung-Chul Han terms that “psychopolitics” of neoliberal debt relations. This examination serves as the ground from which I devise a new kind of relation poetics, a heteroglot and immersive literary bricolage that critically reflects neoliberal modes of atomised individualism. Juliana Spahr's Fuck-You-Aloha-I-Love-You serves as a means by which I distinguish poetry about relationality from relational poetry, which in turn gives rise to my own attempt at, and critical analysis of, a relational poem: a vexed interstice of what Jean-Luc Nancy calls “being-with.
Secular Decolonial Woes
Authors: Vizcaíno Rafael 
Published: March 2021

Abstract
This essay builds on a recent intervention made by Mariana Ortega, who has called on philosophers committed to decolonization to avoid reproducing “colonial impulses and erasures” in the very attempt to advance epistemic decolonization. When connected to “practices of un-knowing,” these tendencies become an “affliction,” which Ortega labels with the notion of “decolonial woes.” The author focuses on the reception of the spiritual elements in Anzaldúa's work to identify a specifically secular form of a decolonial woe: the disregard for the potential that spirituality comprises for advancing the project of decolonization. To counter such secularist erasure, this essay offers an interpretation of Anzaldúa's well-known concept of la facultad as a postsecular methodology that can help advance the project of epistemic decolonization.
Effect of Rotational Speed, and Dwell Time on the Mechanical Properties and Microstructure of Dissimilar AA5754 and AA7075-T651 Aluminum Sheet Alloys by Friction Stir Spot Welding
Authors: NASIR Tauqir , KALAF Omer , ASMAEL Mohammed 
Published: March 2021

In the current study, the effects of dwell time and rotation speed on the mechanical properties and microstructure of friction stir spot welded joints of dissimilar aluminum sheet alloys were investigated. Aluminum AA5754 and AA7075-T651 alloys were selected as the work piece. The joint quality, microstructural evolution and mechanical behavior of the welded regions were considerably affected by the welding parameters. The results obtained that rotation speed and dwell time play an important role on welding quality of aluminum sheet. The microstructure images showed the dwell time and rotation speed has great effects on pin penetration and hook deformation. Maximum tensile shear load 806.3 N was produced at 1000 rpm and 2 s dwell time, while the tensile shear load reduced around 25 % with longer dwell time 5 s and high rotation speed 1400 rpm. Moreover, the welding joint microhardness was improved by the decrease of dwell time and increase of rotation speed.

Les inventaires d’espèces dulçaquicoles par analyse de l’ADN environnemental (ADNe) se sont développés depuis une dizaine d’années. Nous présentons ici l’application de cette méthode à l’inventaire des Bivalves d’eau douce de France. De 2015 à 2018, nous avons réalisé plusieurs tests de terrain en France, en choisissant différentes conditions environnementales. Nous avons comparé les résultats des analyses ADNe avec les connaissances sur la répartition des Bivalves à l’échelle de la France métropolitaine, à l’échelle des bassins-versants de la Meuse et du Rhône, et avec des sites ayant fait l’objet d’inventaires poussés, impliquant plusieurs malacologues utilisant les méthodes traditionnelles (observations au bathyscope, plongée hyperbare, tri de sédiment). Nos résultats montrent l’efficacité des analyses d’ADNe pour la détection et la distinction de presque tous les taxons de Bivalves dulçaquicoles de France (à l’exception des différentes espèces de Corbicules et des sous-espèces de la Mulette méridionale Unio mancus Lamarck, 1819). La méthode est commercialisée depuis 2018 et notre base de données comporte fin 2020 plus de 300 sites inventoriés par analyse de l’ADNe. L’analyse de ces résultats montre que certaines espèces peu étudiées, en particulier des espèces des écosystèmes de l’aval, souffrent d’extinctions locales en France. Ils plaident en faveur de la mise en œuvre d’actions de conservation en particulier pour la Cyclade des fleuves Sphaerium solidum (Normand, 1844), la Grande Cyclade Sphaerium rivicola (Lamarck, 1818) et l’Anodonte comprimée Pseudanodonta complanata (Rossmässler, 1835).

Published: March 2021

Background
The associations among maternal depressive symptoms (MDS), mother–child interactions and early child development are poorly understood. This study aimed to explore the role of mother–child interactions on the associations between MDS and child development.

Methods
A cross-sectional study with a multistage sampling method was conducted in rural areas of Central and Western China. MDS, child development outcomes (communication, gross motor function, fine motor function, problem solving and personal social skills) and mother–child interactions were assessed by The Edinburgh Postpartum Depression Scale, the Chinese version of the Ages and Stages Questionnaires and the Multiple Indicator Cluster Surveys, respectively. Regression-based statistical mediation and moderation were conducted using the PROCESS macro for SPSS.

Results
A total of 2,548 participants (mothers: 1,274; children: 1,274) were included in our analyses. MDS was negatively associated with child development outcomes and mother–child interactions partly mediated these associations. The proportion of the mediating effect of mother–child interactions was 7.7% for communication, 8.2% for gross motor, 10.3% for fine motor, 10.1% for problem-solving and 9.5% for personal social domains. In addition, the interaction effects of MDS and mother–child interactions on the communication domain were significant (β = 0.070, 95% CI 0.016, 0.124; p = 0.011). The associations between MDS and child communication abilities were weaker at the high level (simple slope = −0.019, t = − 0.458, p = 0.647) of mother–child interactions than at the mean level (simple slope = −0.089, t = − 3.190, p = 0.002) and the low level (simple slope = −0.158, t = − 4.231, p < 0.001). Similar moderating effects were not observed in the other child development outcomes.

Conclusion
Our results suggest the important role of mother–child interactions on the associations between MDS and early childhood development. Due to the cross-sectional design of this study, these associations require further investigation in prospective studies.

BackgroundThe chimeric leaves ofAnanas comosusvar.bracteatusare composed of normal green parts (Grs) and albino white parts (Whs). Although the underlying mechanism of albinism inA. comosusvar.bracteatusleaves is not fully understood, it is likely associated with the chlorophyll (Chl) biosynthesis. In this biosynthetic process, porphobilinogen deaminase (PBGD) plays a crucial role by catalyzing the conversion of porphobilinogen (PBG) to uroporphyrinogen III (Urogen III). Therefore, its encoding geneAbhemCwas investigated here in association with Chl biosynthesis and albinism in chimericA. comosusvar.bracteatusleaves.MethodsThe Chl content, main Chl biosynthesis precursor content, and main enzyme activity were determined and compared between the Whs and Grs ofA. comosusvar.bracteatusleaves. In addition,AbhemCwas cloned and its transcriptional expression and prokaryotic protein expression were analyzed. Furthermore, RNAi-mediated silencing ofAbhemCwas produced and assessed in tobacco plants.ResultsThe concentration of Chl a and Chl b in the Grs was significantly higher than that in the Whs, respectively. Additionally, the content of the Chl biosynthesis precursor Urogen III decreased significantly in the Whs compared with the Grs. Thus, the transition of PBG to Urogen III may be the first rate-limiting step leading to albinism in the chimeric leaves ofA. comosusvar.bracteatus. The geneAbhemCcomprised 1,135 bp and was encoded into a protein with 371 amino acids; phylogenetically,AbhemCwas most closely related tohemCof pineapple.Prokaryotic expression andin vitroenzyme activity analysis showed that the cloned mRNA sequence ofAbhemCwas successfully integrated and had PBGD activity. Compared with control plants, transgenic tobacco leaves with pFGC5941-AbhemC-RNAi vector were substantially less green with significantly reducedhemCexpression and Chl content, as well as reduced PBGD enzyme activity and significantly decreased content of Chl biosynthesis precursors from Urogen III onwards. Our results suggest that the absence ofhemCexpression reduces the enzyme activity of PBGD, which blocks the transition of PBG to Urogen III, and in turn suppresses Chl synthesis leading to the pale-green leaf color. Therefore, we suggest thatAbhemCplays an important role in Chl synthesis and may be an important factor in the albinism ofA. comosusvar.bracteatusleaves.

Published: March 2021

Background
From the beginning of 2020, COVID-19 infection has changed our lives in many aspects and introduced limitations in the way people interact and communicate. In this paper, we are evaluating the effect of non-pharmaceutical interventions (NPI) in limiting the spread of the Severe Acute Respiratory Syndrome Coronavirus 2 pandemic during a wedding ceremony from Irbid, Northern Jordan. Agent-based modeling was used in a real wedding event that occurred at the beginning of the spread of the pandemic in Jordan. Two infected nationals of Jordan, who arrived in Jordan about a week before the event, initiated the spread of the pandemic within the contact community.

Methods
In this work, a strict national NPI that the government implemented is developed by using an abstract model with certain characteristics similar to the Jordanian community. Thus, the Jordanian community is represented in terms of ages, occupations, and population movements. After that, the extent of the impact of the NPI measures on the local community is measured.

Results
We observed the deterioration of the state of society while the epidemic is spreading among individuals in the absence of preventive measures. Also, the results show that the herd immunity case was an epidemic, with a high level of spread among the community with 918 cases during a short interval of time. On the other hand, the preventive measures scenario shows a totally controlled spread with only 74 cases applied on the same interval of time. Furthermore, a convergence in the actual results of the real system with the hypothetical system were detected in the case of applying the strict NPI measures. Finally, strict NPI at the community level following social gatherings seem to be effective measures to control the spread of the COVID- 19 pandemic.
Predictors of Spontaneous Conception Following Myomectomy among Women with Infertility at Federal Medical Centre Yenagoa, Nigeria
Authors: Howells Ikobho Ebenezer , James Omietimi E. , Abasi Isaac Joel 
Published: March 2021

Background: Uterine fibroid or leiomyoma (myoma) is the commonest uterine neoplasm in women, and it has been associated with infertility. Though it’s not regarded as a direct cause, surgical removal (myomectomy) has been reported to increase the spontaneous conception rate in women with infertility.
Objective: The objective of this study was to determine the factors associated with conception after myomectomy in women with infertility. It would determine the pregnancy rate, demographic, and surgical factors (pre and postoperative factors).
Materials and Methods: This was a retrospective observational study of 107 women who had myomectomy during the study period, out of these, 68 were done for infertility. The case notes of these women were retrieved, and information related to demographic factors obtained was: maternal age, parity, address, tribe, educational level, and occupation. The preoperative surgical factors obtained were previous history of myomectomy, indication for myomectomy, the size, number and location of myomas, and the caliber of the surgeon. Postoperative surgical data collected include conception, interval between myomectomy and conception, pregnancy outcome, mode of delivery, and fetal sex and birth weight. Categorical variables were compared with chi square and odds ratio, and the degree of association for quantitative variables was determined using Pearson’s correlation coefficient. Predictor variables were determined using simple logistic regression, and multivariate analysis.
Results: The infertility rate among the women who had myomectomy was 63.6%, the conception rate was 14.7%, and the mean myomectomy to pregnancy interval was 9.20 ± 1.24 months. The factors that favor conception were: younger women P = 0.003, uterine size ≤ 16 weeks odds ratio = 3.50(0.14, 84.20), high parity (p = 0.002), solitary fibroid odd ratio = 2.65(0.44, 16.04), tertiary education P = 0.0001 and surgery by consultants P = 0.004. Others were absence of submucous myomas, and pelvic pathology at laparotomy. Using multivariate analysis, the most significant predictors for conception were age and parity, accounting for 10.7%, and all the factors put together could only explain 36.5%.
Conclusion: The conception rate following myomectomy in Yenagoa was relatively low, and the most important predictors were maternal age and parity. The bulk of the factors (65.5%) that determine conception are outside the scope of our study; these could be male factor infertility, factors within the tubal lumen, unidentified uterine synechia, and ovarian failure.

Introduction: Helicobacter pylori infection is associated with gastrointestinal diseases including atrophic gastritis and gastric cancer. Epidemiologic studies have demonstrated associations between H. pylori infection andextra gastrointestinal organ involvements including coronary artery disease and peripherical artery disease, dyslipidemia, insulin resistance and hematologic disorders. We sought to evaluate the prevalence of H. pylori infection in patients suffering cardiovascular diseases attending the Yaounde Central Hospital.
Materials and Methods: Patients suffering from various cardiovascular complications were recruited at the Yaounde Central Hospital, between January and May 2019. The clinical and socio-demographic information of the patients was recorded. Five ml of blood were collected aseptically for Pepsinogen I and II enzymes, gastrin17 hormone and IgG anti H. pylori anti-body. The test parameters were analyzed using a GastroSoft software application. The data was analyzed using Epi Info 7.0. All statistics were 95% CI. Ethical clearance was also obtained from the National Ethics Committee. The study was accepted by the authorities of the Yaounde CentralHospital. All patients signed an informed consent form.
Results: A total of 62 subjects were recruited aged 30-75 years, (mean±SD 52.03 ± 12,78 years); 34(54,84%) females aged 30 to 75years (mean±SD 54,47 ± 13,47 years) and 28 (45,16%) males aged 30 to 65,(mean±SD 49,07± 11,44years). Female/male ratio was 1:2. H. pylori seropisitivity occurred in 58 (93,55%) of the subjects (IgG ≥30 EIU). H. pylori seropositivity was significantly associated with high blood pressure (RR=2.2 95%C.I 1.67 -2.96, p=0, 024). Significantly low Triglyceride concentrations were observed in H. pyloripositive(0,51±0,03g/l) compared to negative subjects (1,04 ± 0,50g/l), (p=0.03). A significant inverse correlation was observed between IgG levels and blood glucose levels (r= 0,4 p=0, 004).
Conclussion: The study indicates that H. pylori infection is highly associated with various cardiovascular complications and disease risk factors.

Published: March 2021

Multiple sequence analysis is one of the most widely used model in estimating similarity among genotypes. In a bid to access useful information for the utilization of bush mango genetic resources, nucleotide sequences of eight bush mango (Irvingia gabonensis) cultivars were sourced for and retrieved form NCBI data base, and evaluated for diversity and similarity using computational biology approach.
The highest alignment score (26.18), depicting the highest similarity, was between two pairs of sequence combinations; BM07:BM58 and BM12:BM69 respectively, while the least score (19.43) was between BM01: BM13. The phylogenetic tree broadly divided the cultivars into four distinct groups; BM07, BM58 (cluster one), BM01 (cluster 2), BM15, BM13 and BM35 (cluster 3), and BM12, BM69 (cluster 4), while the sequences obtained from the analysis revealed only few fully conserved regions, with the single nucleotides A, and T, which were consistent throughout the evolution.
Results obtained from this study indicate that the bush mango cultivars are divergent and can be useful genetic resources for bush mango improvement through breeding.

Aim: For the Method development and validation of Anabasine and Nornicotine in human plasma LC-MS/MS technique is used.
Methodology: Operated in positive electron spray ionization which removes the hardness in ions. Metoprolol is used as an internal standard. Mass analyzers are used to determine the mass to charge ratio. Liquid chromatography separates mixture components in the basis of differences in affinity for stationary and mobile phase. It removes undesired impurities. It increases reproducibility, sensitivity, robustness, detection of low-level proteins. C18 Column (Phenomenex Luna C18, 5 μm, 50*4.6mm ID) is used to for high resolution and peak area. Calibration curve is constructed with the help of linear regression. During the entire process no instability is found.
Results: m/z values of Anabasine are 162.84(Q1), 134.68(Q3) and for Nornicotine are 148.90(Q1), 79.82(Q3). Back calculated curve is calculated at different concentrations from 1-1000ng/ml and their accuracy range from 97-105% for Anabasine and 93-108% for Nornicotine. In Anabasine and Nornicotine the precision and accuracy are calculated by Intra-batch and inter-batch. In the process of multi-step preparation, consider n=6 for intra-batch and n=18 for inter-batch the values obtained are between the nominal concentrations i.e., 90-110%. For each analyte the coefficients of variation are below nominal criteria <15%. For Anabasine and Nornicotine the average recovery rate is 98.3% and 94.3%.

Background
Relationship between outcomes of major hepatectomy and the mortality rate predicted by National Clinical Database Risk Calculator (NCD-RC) was examined.

Methods
Patient demographics and postoperative morbidity and mortality were compared between 30-day and in-hospital mortality rates among 55 patients who underwent major hepatectomies. The cutoff value for high-risk mortality was set at 5%. Patients were divided into 4 groups: (1) no severe complications and low predictive mortality rate (woML), (2) severe complications or mortality, and low mortality rate (wML), (3) no severe complications and high mortality rate (woMH), and (4) severe complications or mortality, and high mortality rate (wMH).

Results
Morbidity higher than Clavien Dindo III occurred in 17 patients (28%) and 30-day and in-hospital mortality in none and 2 (3%), respectively. The in-hospital mortality rate was significantly higher for male patients (P &lt; 0.01). Age, elderly patients, diseases, and comorbidity did not significantly differ among groups. Although bile leakage was common in group wML, there were no in-hospital deaths. All surgical procedures performed in group wMH were right hepatectomy with bile duct resection (RH-BDR) for biliary malignancy, and 2 died of hepatic failure; however, the incidence of RH-BDR was not significantly higher than those in other groups.

Conclusions
Preoperative mortality rate predicted by NCD-RC was not always consistent with outcomes in actual clinical settings and further improvements are needed. In case of RH-BDR for biliary malignancy with high predictive mortality rate, careful decision making for liver function and perioperative management are required.
