PERTINENT ILLS CONCOMITANT WITH MATRIFOCALITY IN ZIMBABWE: IMPLICATIONS FOR DEVELOPMENT
Authors: MAFA ITAI 
Published: March 2021

Objective: The paper explored the challenges underpinning matrifocality in Zimbabwe, what is normally termed single motherhood. With the marital institution losing eminence in Africa due to a myriad of factors such as globalization, industrialization, and eurocentrism; this has greatly altered today’s family structure. The study was anchored on the realization that the traditional composition of an African family which recognized extended families has now been overshadowed by the surfacing of nuclear families as well as an increase in matrifocal families.
Methods: The article utilized a qualitative approach and a case study design. Convenience sampling was used to select 16 single mothers and a purposive sampling method was preferred to sample three key informants. For single mothers, in a mini-depth interviews were used to elicit detailed information and focus group discussion was adopted for key informants. Data were analyzed using the thematic process to integrate the findings.
Results: Stress-induced pathologies, relational conflict within the family set-up, economic privations, communal cynicism, and ostracism were identified as challenges compromising the development and stability of matrifocal families in Chiredzi district.
Conclusions: Guided by various feminism lenses and the ecological perspective, the article shifts from the pathological view to single motherhood, advocating for the need to focus the dialogue along the challenges faced by matrifocal families in an attempt to recommend interventions that can strengthen this family set-up.

COUNTING THE NUMBER OF SUBGROUPS AND NORMAL SUBGROUPS OF THE GROUP <em>U</em><sub>2<em>np</em>, <em>p</em></sub> IS AN ODD PRIME
Authors: Shelash Haider Baqer 
Published: March 2021

The aim of this paper is to compute the number of subgroups and normal subgroups of the group $U_{2np}=\langle a,b\mid a^{2n}=b^{p}=e, aba^{-1}=b^{-1} \rangle$, where $p$ is an odd prime. Suppose $n=2^r\prod_{1 \leq i \leq s}p_{i}^{\alpha_{i}}$ in which $p_i$'s are distinct odd primes, $\alpha_i$'s are positive integers and $t=\prod_{1 \leq i \leq s}p_{i}^{\alpha_{i}}$. It is proved that the number of subgroups is $2\tau(2n)+(p-1)\left(\tau(\frac{n}{p})+\tau(\frac{n}{2^r}) \right)$, when $p \mid n$ and $2\tau(2n)+(p-1) \left[ \tau(t)\right]$, otherwise. It will be also proved that this group has $\tau(2n)+\tau(n)$ normal subgroups.

Authors: Boztaş Neslihan , Küçükaslan Mehmet 
Published: March 2021

Let p(n) and q(n) be nondecreasing sequence of positive integers such that p(n) < q(n) and limn→∞ q(n) = ∞ holds. For any r ∈ Z^+, we define D_p,q^+r- statistical convergence of ∆^+r x where ∆^+r is r- th difference of the sequence (x_n). The main results in this paper consist in determining sets of sequences χ and χ' of the form [D_ p^q]_0 α satisfying χ ⊂ [D_p^q]_0(∆^+r ) ⊂ χ ' and sets φ and φ' of the form [D_p^q]_α satisfying φ ≤ [D_p^q]_∞(∆^+r ) ≤ φ' .
ON THE NUMERICAL RANGE OF EP MATRICES
Authors: Pappas Dimitrios 
Published: March 2021

In this work we study the numerical range $W(T)$ of EP matrices or operators having a canonical form $T = U(A\oplus 0)U^* $ in the case when $0 \notin W(A)$. As a result, we define the distance $d(W(A,T))$ between the sets $W(A)$ and $W(T)$ and investigate their connenctions, giving also upper and lower bounds for the distance $d(W(A^{-1},T^\dagger))$. Finally we present the form of their angular numerical range $F(T)$ and its connection with $F(T^\dagger)$.
Funnel trap as a method for capture migrating bats in Pape, Latvia
Authors: Keišs Oskars , Spalis Donats , Pētersons Gunārs 
Published: March 2021

We constructed a large funnel trap on the coast of the Baltic Sea on dunes of Pape village, Latvia. The trap has been used during the peak autumn migration of bats in Latvia in August and September. During the period of 2014 – 2020, about 40 thousand bats were captured in the trap, mostly Nathusius’ Pipistrelle Pipistrellus nathusii, about 35 thousand individuals. In migration hotspots of bats, this is suggested method of trapping since large number of bats might be trapped without entangling bats in mist-nets.

Investor Relations, Engagement, and Shareholder Activism
Authors: Chapman Kimball L. , Miller Gregory S. , Neilson Jed J. , White Hal D. 
Published: March 2021

ABSTRACT
A dedicated investor relations (IR) function facilitates direct and ongoing dialog between management and shareholders. This paper examines whether this form of engagement mitigates activism that relies upon support from other shareholders. We find that IR engagement is associated with increased investor confidence in management and the board, as well as a lower likelihood of activism, with this deterrent effect becoming stronger when there are fewer frictions surrounding the development of mutual understanding and trust with investors. We also find that when firms do experience an activist campaign, firms with IR engagement have less costly and contentious campaigns, including a lower likelihood of CEO turnover, than those without such a commitment. Taken together, our findings suggest that direct and ongoing IR engagement is an important factor in achieving mutual understanding and trust between the firm and its shareholders, which deters activist investors and mitigates the costly escalation of initiated campaigns.

Green bean sprouts are a type of vegetable that has a short shelf life. To extend the shelf life of these vegetables, they need to be stored by appropriate packaging methods. The aim of this study was to apply polyethylene (PE) and polypropylene (PP) plastic packaging to increase the shelf life of mung bean sprouts. The research was conducted by packing mung bean sprouts in PE and PP plastic at storage temperatures of 10 and 29 °C for 9 days. The parameters observed were weight loss, respiration rate, color, moisture content, and aroma. The results showed that mung bean sprouts stored in PE packaging had a longer shelf life than PP packaging. The shelf life of mung bean sprouts using PE packaging is 5 days, while PP packaging can only last 3 days at 10 °C. The shelf life of mung bean sprouts using PE packaging is 4 days, while the PP packaging can only last 2 days at 29 °C. Keywords: green bean sprouts, packaging, PE plastic, storage, temperature

Published: March 2021

This research aims to evaluate the CHIRPS data in estimating daily rainfall in West Papua compared with automatic weather stations (AWS) data recording. The data used in this research are daily CHIRPS data and AWS daily data recording 1996 to 2020 from AWS Rendani–Manokwari, AWS Jefman–Raja Ampat, AWS Torea–Fakfak, and AWS Kaimana–Kaimana. CHIRPS data were evaluated using the Point to Pixel method based on numerical and categorical parameters i.e., root mean square error (RMSE), mean error (ME), mean absolute error (MAE), Pearson correlation (r), probability of detection (POD), critical success index (CSI), and T-test. The research showed that CHIRPS had a significant difference to AWS data in estimating daily rainfall in West Papua based on a T-test. However CHIRPS has a moderate accuracy in estimating daily rainfall in West Papua with RMSE = 8.59 mm, ME=2.75 mm, and MAE = 5.15 mm and had a moderate positive correlation with AWS data with r= 0.43. Besides, CHIRPS has good accuracy in detecting rain events in West Papua indicated by a POD = 0.72 and CSI = 0.43. Therefore, CHIRPS data can be used as an alternative solution for providing rainfall data in West Papua. Keywords: satellite observation, rainfall predictor, point to pixel

Aims
Pulmonary vein isolation (PVI) using cryoballoon ablation (CBA) is mainly reserved for patients with drug-refractory or drug-intolerant symptomatic atrial fibrillation. We evaluated a large cohort of patients treated in a real-world setting and examined the safety and efficacy profile of CBA when applied as a first-line treatment for atrial fibrillation.

Methods
In total, 249 patients (23% women; 56 ± 13 years; mean left atrial diameter 41 ± 7 mm; 73.5% paroxysmal atrial fibrillation; and 26.5% persistent atrial fibrillation) underwent an index PVI by CBA. Data were collected prospectively in the framework of the 1STOP ClinicalService project, involving 26 Italian cardiology centers.

Results
Median procedure and fluoroscopy times were 90.0 and 21.0 min, respectively. Acute procedural success was 99.8%. Acute/periprocedural complications were observed in seven patients (2.8%), including: four transient diaphragmatic paralyses, one pericardial effusion (not requiring any intervention), one transient ischemic attack, and one minor vascular complication. The Kaplan--Meier freedom from atrial fibrillation recurrence was 86.3% at 12 months and 76% at 24 months. Seventeen patients (6.8%) had a repeat catheter ablation procedure during the follow-up period. At last follow-up, 10% of patients were on an anticoagulation therapy, whereas 6.8% were on an antiarrhythmic drug.

Conclusion
In our multicenter real-world experience, PVI by CBA in a first-line atrial fibrillation patient population was well tolerated, effective, and promising. CBA with a PVI strategy can be used to treat patients with paroxysmal and persistent atrial fibrillation with good acute procedural success, short procedure times, and acceptable safety.

INVENTORY OF SNAKES: COMPARATIVE ANALYSIS AROUND PARANÁ RIVER BETWEEN THE NORTHWEST OF THE STATE OF SÃO PAULO AND EAST OF THE STATE OF MATO GROSSO DO SUL

ABSTRACT
This paper aims to inventory snakes species found in the border of both São Paulo and Mato Grosso do Sul States, around Paraná River, having as reference the municipalities of Santa Fé do Sul (SP) and Aparecida do Taboado (MS), including bordering municipalities. Data about snake’s incidence in that region was collected with the help of the community, Fire Brigade and Health Secretary. At first, it was reported, a total of 11 genres, 12 species, and 34 specimens of snakes distributed in four families (Boidae, Elapidae, Viperidae and Dipsadidae). In São Paulo northeast 10 species were found, 3 of them were only found in São Paulo, whereas in Mato Grosso do Sul, 19 species, 2 of them were found in Mato Grosso do Sul. All the other species were found in both States. It was recorded that the incidence of Boa constrictor is notoriously higher than the incidence of other species, being 60% higher than the second one for Erytrolamprus Poecilogyrus. It is a comparative analysis, thus there is not a big difference in the total number of species for both States. Regarding health issues, the data presented a higher quantity of ophidian accidents in the city of Paranaíba in the State of Mato Grosso do Sul.

Published: March 2021

En este trabajo se presentan los resultados obtenidos en una investigación realizada en 31 entidades penitenciarias españolas y, tiene por objeto analizar el acceso de las mujeres penadas a los distintos niveles educativos, especialmente en los estudios medios o superiores, y su relación con distintos factores de riesgo y protección intervinientes. La muestra global (310 mujeres, 30,1%) se ha seleccionado utilizando muestreo bietápico, de la población de mujeres en cumplimiento de condena en medio abierto. La metodología que se ha usado combina métodos cuantitativos y cualitativos, aplicados a los instrumentos desarrollados diseñados ad hoc (cuestionario de mujeres y entrevistas personales, y cuestionario de profesionales). Los resultados muestran que la mayor parte abandonan los estudios en las enseñanzas básicas, observándose distintos factores de riesgo; sin embargo, las pocas que continúan o retoman los estudios medios o superiores en prisión, lo consideran como un factor de protección frente al ambiente penitenciario, permitiéndoles gestionar de forma inteligente y saludable el tiempo en contextos penitenciarios, mejorando las relaciones entre las presas, con las familias y los trabajadores de prisión. También consideran que les puede resultar útil para el futuro, especialmente, en el ámbito laboral.What do you want to do ?New mailCopy What do you want to do ?New mailCopy What do you want to do ?New mailCopy What do you want to do ?New mailCopy

This paper presents the results of petrographic study of sedimentary iron ore from surface strata of the Shendi-Atbara Basin, River Nile State, Sudan. The aims of this study are to investigate the geological behavior and geological conditions affecting precipitation of sedimentary iron ore. The methodologies have been used to realize the objectives of this study include field work, office work and laboratory work including thin sections and polished sections analysis. According to field observation sedimentary iron ore can broadly be considered as occurring in three major classes:Ferribands iron, ferricrete iron and oolitic iron ores. The modes of occurrence of iron ore were described at the outcrops and vertical sedimentary profiles revealed that the iron occurred in the study area at different types in stratigraphic sequence such as cap, bedded and interbedded conformable with Shendi Formation. Petrographic study of iron ore in collected samples using polarized microscope and ore microscope includes study of the textures and structures of ores to obtain ore history. The main types of textures and structures in studied samples are oolitic, granular, lamellar and bands.According to these results the origin of iron ore is formed by chemical precipitation during chemical weathering of surrounding areas in continental lacustrine environment. The iron ore in study area is potential for future mining works and steel industry
