Providing Accessible Healthcare for Autistic Women
Authors: Henry Karen
Published: February 2023

Narratives by autistic women regard their maternity-care experiences with feelings such as being isolated, neglected, stigmatised and judged. They feel hospital environments overload their senses which causes barriers to accessing maternity care. I have spent some time researching and creating a series of support plans to invite conversations between autistic women and maternity staff to create accessible, meaningful healthcare encounters. The aim of this article is to provide some ideas for care adjustments so that future narratives overflow with positive encounters.
Decolonising the Midwifery Curriculum
Authors: Allan Georgia , Thomas Sheridan
Published: February 2023

Decolonising the midwifery curriculum means to understand the historical and political effects of colonialism on healthcare, and how those accessing maternity care can still be disadvantaged by it today. Decolonising the midwifery curriculum is readdressing the imbalance in Eurocentric content that reinforce Western dominance, ensuring that taught content represents all cultures and fosters a sense of shared understanding and cultural humility. It is a process that asks us to challenge ourselves and institutional power imbalances that perpetrate harmful bias towards ethnicity, class, gender and able-bodism, to produce midwives who are better equipped to provide culturally-safe and inclusive care.
Oil palm (Elaeis guineensis) genetic resources for abiotic stress tolerance: A review
Authors: MURUGESAN P , ASWATHY G M , KUMAR K SUNIL , MASILAMANI P , KUMAR VINOD , RAVI V
Published: February 2023

Oil palm (Elaeis guineensis Jacq.) once grown widely in forests and adjoining areas was subsequently domesticated as a plantation crops. Global oil palm area has quintupled from 1990 and it is grown in an area of 17 million ha with a palm oil production of 59.42 million tonnes. Oil yield is dependent not only on genotypes but also on environmental factors. The growth of common oil palm varieties is suppressed at temperatures below 15Â°C. Oil palm is a drought tolerant crop as it is surviving in locations with a dry season of several months. Nevertheless water deficit stress reduces the palm fresh fruit bunch yield to less than 5 tonnes/ ha along with significant reduction (up to 26.30%) in vegetative growth. Excess soil moisture and continuous water logging are detrimental to oil palm fresh fruit bunch production. The important parameters, viz. the root biomass, potential root extraction ratio (PRER), rate of stomatal conductance and photosynthesis can be used for screening oil palm genotypes for drought tolerance. The progenies of Bamenda Ã— Ekona and Tanzania Ã— Ekona hybrids had drought tolerance and produced 40-42 tonnes of fresh fruit bunch during initial three years. The progenies of crosses between Deli Ã— Yangambi (NIFOR, Nigeria), Bamenda Ã— Ekona (ASD Costa Rica), Tanzania Ã— Ekona and IRHO7010 were reported to adapt to prolonged drought conditions in Nigeria, Costa Rica and Colombia, respectively. Cameroon and Tanzanian genetic sources had cold tolerance and hybrids of Dami Deli Ã— Cameroon /Tanzania crosses and Amazon (variety) are available with Agricultural Services Development, Costa Rica. Elaeis oleifera has inherent characteristics to tolerate drought and water stagnation, pest and disease resistance and exhibits slow vertical growth. ASD Costa Rica had developed compact palm utilising the genetic resources of E.oleifera. Varieties with short leaves and slow vertical growth are most preferred traits in oil palm industry to increase the productivity per unit area as they can be planted at high density. Information on early maturing varieties, dwarfness, rapid and quality planting material production technologies in relation to abiotic stress tolerance for oil palm are scanty.

Published: February 2023

Four apple (Malus × domestica Borkh) varieties (Starkrimson, Cooper IV, Red Chief, and Mollies Delicious) were planted at 3 planting densities (1600, 1142 and 952 plants / ha) on semi-dwarf rootstock during 2002-03 and data on yield and growth were recorded after 7 years. Results indicated that maximum mean trunk cross sectional area was registered in Mollies Delicious at all the densities (103.79, 92.61 and 77.06 cm2) and lowest (67.01, 75.65 and 80.33 cm2) in Cooper IV. Largest sized fruit (177.80 g/ fruit) recorded in the S3 (952 tree/ha) and minimum (160.73 g/ fruit) in S1 density (1600 tree/ha). Maximum mean yield and yield efficiency were recorded in Starkrimson and Red Chief and minimum yield and yield efficiency in Cooper IV. Density has a detrimental effect on yield efficiency, it was maximum (0.48 kg/cm2) in S3 and minimum (0.21 cm2) in S1 density. The fruit weight increases with decrease in plant density, fruit size has negative correlation with number of fruit tree. Positive correlation was obtained between yield and yield efficiency (0.999) and planting densities with yield efficiency (0.691).
Diagnosis and management of soil fertility constraints in coconut (Cocos nucifera) : A review
Authors: MALHOTRA S K , MAHESWARAPPA H P , SELVAMANI V , CHOWDAPPA P
Published: February 2023

Coconut (Cocos nucifera L.) is an important perennial plantation crop and to improve the productivity, the innate soil constraints should be ameliorated. The red, lateritic and sandy coconut soils are suffering with soil acidity, low CEC and poor nutrient reserve. A study on nutrient removal by coconut provides guidelines for the fertilizer input required. The effect of soil nutrient imbalance on the availability of nutrients emphasize the need based balanced fertilizer supply to coconut soils. The built up of soil available P in acidic red soils under continuous phosphatic fertilizer application strengthens the need to realize the soil test based fertilizer application. The potassium supply in the acid soils is poor, coconut being a huge feeder of potassium needs constant supply of potassium. Secondary and micronutrient deficiencies are emerging as potential yield limiting nutrients for coconut. Biomass recycling studies under coconut based cropping systems shows promising results in achieving the nutrient supply with the available biomass recycling through vermicompost. Minimizing the biomass exported out of farm especially coconut husk may improve potassium supply to palms through organic farming. Microbial studies showed that biomass recycling improved the beneficial microorganism in the rhizosphere and thereby enhances the nutrient availability. Fertigation technique showed higher nutrient use efficiency, soil and water conservation measures improved the yield of coconut in sandy soil and checks the losses through run-off and erosion in sloppy soils. Site specific soil management strategies can improve the coconut yield in an eco-friendly way.

Published: February 2023

A study was carried out at Student's Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana during rabi 2010-11 and 2011-12. The experimental site was sandy loam, with normal soil pH and electrical conductivity, low in organic carbon and available N and medium in available P and K. The investigation consisted of 11 treatments each having different population levels of button weed (Malva neglecta) and kandyali palak (Rumex spinosus), viz 0,3,6,9,12 plants/m2 and two treatments having pure populations of each weed. Wheat crop accumulated more heat units (AGDD, AHTU, APTU) during the year 2011-12 as compared to the crop year 2010-11. Increase in population levels of both weed species significantly decreased the crop growth rate (CGR) and relative growth rate (RGR) of wheat crop. The results showed a significant decrease in number of tillers, effective tillers, number of grains/ear, 1 000-grain weight and grain yield of wheat with increasing population densities of Malva neglecta and Rumex spinosus (from 3 to 12 plants/m2). Highest grain yield of wheat (57.54 q/ha) was recorded under pure wheat treatment and lowest grain yield was recorded in treatments T5 and T10 having 12 plants of Malva neglecta and Rumex spinosus, respectively. Highest heat use efficiency (HUE) was recorded in pure wheat treatment in contrast to all other treatments. Determination of correlation matrix revealed that crop yield was perfectly negatively correlated with population densities of Malva neglecta and Rumex spinosus while there was highly significant direct relationship with other crop growth parameters like dry matter accumulation, LAI, tiller number/m2, effective tillers/m2, ear length, and number of grains/ear etc. Regression analysis interpreted positive relation of grain yield with growth parameters and negative with both weed population densities. From the study it was concluded that higher weed infestation enhances inhibitory influence on the growth rate, heat use efficiency and yield of wheat crop.

Published: February 2023

The present investigation was carried out to estimate the genetic diversity at molecular level using RAPD primers across 23 genotypes of watermelon [ Citrullus lanatus (Thunb.) Mastum and Nakai]. RAPD analysis was conducted using 14 random primers of which eight primers produced 41 bands, 39 being polymorphic, generating 95% polymorphism. Jaccard similarity index based on RAPD revealed 49.6% average similarity with a range of 28% to 86%. The SAHN clustering based on UPGMA algorithms has put genotypes in two groups, one with 5 genotypes and another with 9 genotypes. The 9 genotype were left separately these being most diverse. High within and between group diversity resulted in poor grouping. Moreover clustering did not show any regional pattern. However, some population specific bands suggested regional influence on diversity.

Published: February 2023

Climate change has been given the dubious moniker for asymmetrical development of Indian economy in general and agriculture sector in particular. Climate resilient technologies are promising tool to guard a farming system from climatic variations. National Initiative on Climate Resilient Agriculture (NICRA) has demonstrated, and promoted application of climate resilient technologies in most vulnerable 100 districts. This study has been conducted to recognize the technological and socio-economic impact of these technologies upon the society. To enable impact assessment the study employed with –without and before-after comparison, of samples of two NICRA and two non-NICRA villages constituting 120 respondents. Among the technologies demonstrated in the NICRA villages, improved soil and land management practices, water management practices, crop production interventions and cropping system interventions were compared. Various analyses demonstrated that significant difference between NICRA and non-NICRA, farmers on cropping intensity, crop diversification, average irrigated land area and irrigation frequency, employment generation, land area (leased in) and annual savings, with a favorable tilt towards NICRA group. Before-after comparison of NICRA group, to isolate the project impact also testified significant improvement on a set of indicators like average irrigated land area and irrigation frequency, employment generation, land area (leased in), savings, crop yield and expenditure pattern. The study thus provides a springboard for the policy makers and civil societies to stretch out the activities for wide adaptation.

Published: February 2023

Evaluation of diversity through genetic variability and correlation studies on vegetative and floral characters of gladiolus (Gladiolus hybrida) genotypes were undertaken at experimental farm, KVK, Sangsanggiri, Tura, West Garo Hills District, Meghalaya during 2014â€“16.Twenty two gladiolus cultivars, viz. The Queen, Red Majesty, Applause, Charm Glow, Candyman, Interpid, Eight Wonder, Pacifica, Tiger Flame, Souvenier, American Beauty, Oscar,White Prosperity, Wedding Bouquet, Poppy Tears, Morocco Beauty, Summer Sunshine, Wing Wang Sang, Her Majesty, Green Bay, Priscilla and Red Ginger were selected for their evaluation. The range of variation was high in days taken for floret opening (77.53-119.47). However, highest phenotypic (408.38), genotypic variances (404.45), PCV (53.62) and GCV (53.36) were associated with corm weight. The estimates of phenotypic coefficient of variation (PCV) were higher than genotypic coefficient of variation (GCV) for all the traits. Maximum heritability was also noticed in corm weight (99.38), whereas minimum was observed in number of tillers/plant (40.34).The high heritability with genetic advance as percentage of mean for corm weight indicates the possible role of additive gene action. The magnitude of genotypic correlation was higher than their corresponding phenotypic correlation for most of the traits, indicating a strong inherent linkage between various traits under study. At genotypic and phenotypic level, days for sprouting of corms exhibited highly significant and positive correlation with days for spike initiation and days for floret opening.Vase life was highly significant and positively correlated with rachis length, number of florets/spike, fresh weight of spike, spike girth and field life.

Authors: KUMAR SANJEEV , KUMAR SHIV , CHAHAL VED PRAKASH , SINGH DHARAM RAJ
Published: February 2023

The process of crop diversification towards high-value crops in Uttar Pradesh at regional as well as district level for the period 1990-91 to 2011-12 was examined. Simpson index of diversification and panel data regression analysis were used to analyze the trends and drivers of crop diversification. The results infer that state agriculture is moving from traditional crops to high value crops. This becomes the apt choice of policy makers for boosting agricultural growth. However, this shift is not found evenly distributed across the districts/regions. The irrigation, fertilizers and mechanization were found to be the major drivers of shift in the area towards high value crops and leads to less diversification. On the other hand, access to primary markets has positive impact on diversification. This necessitates the redesign and implementation of different strategies for crop diversification in these regions. The insight emanating from results emphasize not only to arrest the rising intra-regional disparities but also policy support in terms of better marketing infrastructure, easy and cheap access to agricultural credit for the development of irrigation facilities and farm mechanization, availability of fertilizers and appropriate technologies for increasing farm income and improving farmersâ€™ livelihoods.

Delitos sin víctimas
Authors: Castañeda Delgado Oscar Daniel
Published: February 2023

Los delitos sin víctimas son intercambios voluntarios de bienes y servicios entre adultos, fuertemente demandados y que están legalmente proscritos. Algunos ejemplos de estos delitos son la prostitución, el tráfico de drogas, los juegos de azar y la pornografía. La inexistencia de una víctima y la falta de un bien jurídico identificable sirven como base para afirmar que la justificación del Estado para penalizar estas conductas radica en su inmoralidad, lo que atenta contra el principio de ultima ratio, pues la función del derecho penal es la protección de bienes jurídicos y no la de legislar moralidad. Por este motivo, concluimos que se está limitando arbitrariamente la libertad personal de los ciudadanos, y, por tanto, estas conductas deben ser despenalizadas.

Authors: D. Kabiru H. , B. Ahmad K. , S. Idris O. , R. Ahuoiza S
Published: February 2023

Tinea capitis or scalp ringworm is a fungal skin disorder commonly found in children below 12-year-old. The management of ringworm by mean of synthetic drugs continue to face setback as result of antibiotic resistance being exhibited by the disease-causing fungi. Mitracarpus hirtus (L) is a weed plant found on gardens, farms and fields with wide geographical distributions. Pharmacological studies of the plant show its potent antifungal potentials as it is used traditionally for the treatment of skin diseases. The aim of this preliminary study is to examine the antioxidant activities and inhibitory properties of various solvent extracts of M. hirtus leaves against Tinea capitis by standard procedures.  The in vitro antioxidant activities show that all extracts possess moderate radical scavenging properties with IC50 values of 159.12±0.48µg/mL, 832.48±64.53µg/mL, 547.68±12.3553µg/mL and 168.41±5.0 µg/mL for Aqueous Residue, n-hexane, chloroform and ethylacetate extracts respectively. Considerable inhibitory effect on the growth of Tinea capitis was observed from the zone of inhibitions of the extracts with ethylacetate fraction exhibiting highest inhibition as the concentration increases. This study shows the potential of M. hirtus to inhibit the growth of tinea capitis. An extensive research is recommended in order to isolate the compounds responsible for the observed activities of the plant.

Proposal for a High-Performance, Scalable Multiprocessor
Authors: Morreira José Eduardo , Zuffo João Antônio , Kofuji Sérgio Takeo
Published: February 2023

This report describes a proposed architecture for a massively parallel, shared memory computer, using commercially available microprocessors (DEC Alphas). The architecture is scalable from 4 processors to 65536 processors. Each processor has a peak performance of 200Mflops, and therefore this proposed architecture allows us to build systems with peak performance greater than 10 Tflops. Four processors are organized as a tightly coupled multiprocessing cluster. Multiple clusters (up to 8) can share a host, and multiple hosts can be used to build larger systems. Clusters communicate by means of a scalable interconnection network, that allows processors from one cluster to access the memory in a different cluster, thus providing a single memory space. Coherent caches are used to both reduce and hide the latency of inter-cluster communication.

Riskante Rezeption
Authors: Badura Laura
Published: February 2023

For recipients to be able to use journalistic content to form opinions and make decisions, a certain amount of trust is essential. At the same time, every act of trust involves taking risks. Therefore, this book focuses on the relationship between journalism, trust and risk. In order to examine the perception of false, incomplete, distorted and absent information from the recipient's point of view, the author chooses a multi-method approach. Thus, this study is the first to analyse potential causes and consequences of journalistic risk perception—and their implications for both journalism studies and media practice.
„Next Generation EU“
Authors: Waigel Elena
Published: February 2023

The "Nicholas ruling" of the German Constitutional Court sets the tone for the jurisprudential discussion on the possibility of raising European debt by means of an own resources decision. But a final chord was not reached. This publication addresses some of the open questions from the perspective of European law. How is the debt-financed project "Next Generation EU" structured? Can it be based on a legal foundation in European law? How are the refinancing options to be legally assessed? The answers to these questions, together with the case law of the Federal Constitutional Court, will determine the framework for future financial cooperation in the European Union.
Das Übereinkommen zur Beendigung bilateraler Investitionsschutzverträge zwischen den Mitgliedstaaten der Europäischen Union
Authors: Böse Laura
Published: February 2023

The paper examines the Agreement for the Termination of Intra-EU BITs, which fundamentally changes the intra-European investment protection system. In the analysis, a distinction is made between legal and factual elements. The legal assessment provides answers to the questions whether the treaty-based investment protection regime has been effectively terminated and whether the systematic change resulting from the termination is sustainable. The factual analysis shows which concrete consequences result from the termination of intra-EU BITs. Finally, the review of both elements allows for a concrete recommendation for action and an outlook on future intra-EU investment protection law.
Investigation of Genetic Mutations in the Exon-intron Regions of the COL7A1 Gene in five Family Case Reports with Epidermolysis Bullosa in Khuzestan Province
Authors: Ameri Khadije , Moradzadegan Atousa
Published: February 2023

Background: Dystrophic Epidermolysis bullosa (DEB) is one of the EB types caused by a mutation in the COL7A1 gene, which encodes collagen type 7 and is the main component of anchoring fibrils. Objectives: This study aimed to investigate COL7A1 gene mutations in five families of patients. Khuzestan is suffering from EB. Methods: After extracting genomic DNA from peripheral blood samples of probands, COL7A1 gene screening was performed using polymerase chain reaction and direct sequencing of exons 36-37 and their adjacent introns with the Sanger sequencing method. Results: The identified mutations included a new homozygous deletion mutation in exon 36 (c.2669delC) that resulted in a change in the open reading frame. Other obtained variants are the common mutations c.4233delC and c.4233delT in exon 37, which were identified as proline substitution mutations in one mutant allele in the homozygous form and three allele mutants in the heterozygous form. Conclusions: In this study, presenting a new mutation in the COL7A1 gene is the focus of the molecular heterogeneity of DEB. In addition, the efficient identification of COL7A1 gene mutations provides more information for the accurate diagnosis and prediction of the disease, genetic counseling, and prenatal diagnosis.
