Authors: Danovaro-Holliday M. Carolina , Contreras Marcela P. , Pinto Dalys , Molina-Aguilera Ida Berenice , Miranda Diana , García Odalys , Velandia-Gonzalez Martha
Published: March 2019

Objective.To develop a methodology to assess electronic immunization registries (EIRs) in low- and middle-income countries (LMICs) in Latin America and the Caribbean.

Methods.A team from the Immunization Unit at the Pan American Health Organization (PAHO) reviewed existing methodologies to evaluate health information systems, particularly the Performance of Routine Information System Management (PRISM) framework and methodologies used to assess information systems. In 2014, the PAHO team convened a small working group to develop an evaluation approach to be added to the existing World Health Organization immunization data quality self-assessment (DQS) tool. The resulting DQS with an added EIR component was named “DQS Plus.” The DQS Plus methodology was used in Panama in May 2014 and in Honduras in November 2015.

Results.The DQS Plus tool proved feasible and easy to implement in Panama and Honduras, including by not adding much time or resources to those needed for a usual DQS. The information obtained from the DQS Plus assessment was practical and helped provide health authorities with recommendations to update and improve their EIR, strengthen the use of the registry, and enhance the data the assessment produced, at all levels of the health system. These recommendations are currently being implemented in the two countries.

Conclusions.The DQS Plus proved to be a practical and useful approach for assessing an EIR in an LMIC and generating actionable recommendations. Further work on defining operational and related EIR functional standards in LMICs will help develop an improved EIR assessment tool for Latin America and the Caribbean, and potentially elsewhere.

A porosidade é importante na determinação da qualidade de um solo, por possuir forte influência na aeração, na transferência de água/solutos/gases/calor, na resistência à penetração e ramificação de raízes, além do desenvolvimento de microorganismos. A avaliação do espaço poroso, considerando vazios intra e inter-agregados, em diferentes tipos de solo e suas implicações (vantagens/desvantagens) é objetivo deste estudo. Foi determinada a porosidade inter e intra-agregados em solos dos tipos Latossolo Vermelho Distrófico e NeossoloRegolíticoEutrófico. Para os intra-agregados foram classificados: o tamanho, a forma e a inclinação. A porosidade inter-agregados foi maior para o Neossolo; este é um comportamento esperado para um solo arenoso, quando comparado a um solo argiloso. Considerando a porosidade intra-agregados, destacou-se a predominância da inclinação horizontal, poros maiores e maior quantidade de poros complexos para o Neossolo. A aplicação de tomografia computadorizada de raios-x se mostrou eficiente na caracterização micromorfológica da porosidade do solo.
Fall Detection from Thermal Camera Using Convolutional LSTM Autoencoder
Authors: Nogas Jacob , Khan Shehroz , Mihailidis Alex
Published: March 2019

Human falls occur very rarely; this makes it difficult to employ supervised classification techniques. Moreover, the sensing modality used must preserve the identity of those being monitored. In this paper, we investigate the use of thermal camera for fall detection, since it effectively masks the identity of those being monitored. We formulate the fall detection problem as an anomaly detection problem and aim to use autoencoders to identify falls. We also present a new anomaly scoring method to combine the reconstruction score of a frame across different video sequences. Our experiments suggests that Convolutional LSTM autoencoders perform better than convolutional and deep autoencoders in detecting unseen falls.
Marital Rape; A Myth or Fact?
Authors: Huzaifa Sarfaraz
Published: March 2019

Marital rape is one of the serious issue in all over the world. Marriage is a relationship where things are better worked when they are in mutual understanding and acceptance; any deed which is with force or without consent is considered unfair. Likewise, forced sex with spouse or to demand sex without consent is considered as marital rape, but still in many countries and culture it is not considered any serious issue, moreover this topic is considered a taboo which should not be discussed inside or outside of the family.
The prevalence and perceived impacts of early marriages: A Study on women in Rural Pakistan

Published: March 2019

The prevalence of early marriage has been well documented in developing countries, however women’s own perspectives on the practice are less well recognized. This study sought to explore female perspectives on early marriage in rural Pakistan in order to further understand its immediate origins and outcomes. A total of 56 participants were recruited and interviewed, with an array of probing questions htat investigated the social and cultural context of their marriages. Of those interviewed, 14.3% were married before the age of 15 and 30.4% of women were married between the ages of 15 and 18, indicating that only 55.4% of the respondents were married after reaching the legal age, in Sindh, of 18 years old. Furthermore, 51.8% and 57.1% of women responded “YES” when asked whether their marriage affected their education and health, respectively. Approximately 21.4% of women felt their marriage affected their social life, and 46.4% felt it impacted their professional careers. In determining the cause for marriage, 75% of women agreed that it was largely due to family pressure, and when asked about the cultural context of the marriage, 82.1% of females responded that cultural norms and practices were highly influential in determining their age at marriage. Only 57.1% of women agreed their marriage was by choice, and women who indicated they were satisfied with the marriage also noted they had no choice but to be satisfied. Early marriage is still an extremely prevalent phenomenon in rural Pakistan, especially in rural Sindh, despite the laws forbidding the practice. In order to effectively combat forced child marriage, there needs to be a higher emphasis on gender equality in education that eventually overturns deep rooted cultural norms, and further initiatives that lift families out of poverty and empower women by increasing female autonomy and women’s options outside of their household/childbearing roles.
Non-medical preimplantation gender selection. A clear gendercide and sexism in Pakistan.
Authors: Neelam Barkat Ali
Published: March 2019

Assisted reproductive technology (ART) advances since the birth of Louis brown in 1978 since then this field introduces innovative techniques such as preimplantation genetic diagnosis. This technique offer the opportunity to fertile and infertile couples to select sex of their offspring prior to implantation via in-vitro fertilization (IVF). These techniques in Pakistan are practicing since three decades without any legislative authorities that actually favors to choose a son instead of a daughter. This accounts as an unethical tradition in international market which also indicates a substantial social harm to our state in coming future. Non-medical sex selection is believe to be exhibits sexism and gendercide, which can threatens the psychological welfare and future liberties of the child. Also it promotes a common social stereotype of sex upon children from the moment of their birth and create uneven gender distribution which can lead to a social devastation like; incidence of child marriage and sex trafficking, kidnapping and selling of women, fraternal polyandry etc. This section, mainly in Pakistan, making a call for legal and regulatory possibilities, enforcing a ban on non-medical sex selection for its contribution to gender inequality and gendercide.

Actualmente, el gobierno federal promueve el pago por captura de carbono en los bosques para mitigar el calentamiento global. Por ello, existe la necesidad de estimar la biomasa y tasas de captura de carbono en los bosques de Abies religiosa. En este estudio se generaron modelos para calcular la biomasa de fuste, de madera de ramas y de acículas de árboles completos y de ramas de oyamel en rodales del Cerro Tláloc, Texcoco, Estado de México. Para el caso de árboles completos, la biomasa estuvo en función del diámetro normal (DN), mientras que para ramas individuales fue una función del diámetro basal (DB). El uso de los modelos generados a nivel árbol se recomienda para árboles con DN entre 12 y 105 cm, n cambio los modelos a nivel de ramas se recomiendan para diámetros basales entre 1 y 120 mm. El modelo para fustes fue de tipo potencial y los de madera de ramas y follaje de árboles completos de tipo exponencial. Los coeficientes de determinación de los modelos a nivel árbol indican que existe una considerable variabilidad, principalmente, en las biomasas de ramas, lo que puede ser consecuencia del proceso de declinación en la zona de estudio. La biomasa total de los árboles se distribuye en forma atípica entre los compartimentos aéreos: 97 % en los fustes, 3 % en madera de ramas y 0.07 % en follaje. Este patrón de distribución de biomasa refleja el efecto del deterioro de los bosques de A. religiosa.

GADAI DALAM SYARI'AT ISLAM
Authors: Misno Abdurrahman
Published: March 2019

Manusia tidaklah selamanya berkecukupan harta, ada masa-masa dimana ia sangat membutuhkan uang untuk memenuhi kebutuhan hidupnya. Jika melihat kenyataan di masyakarat maka didapati banyak orang yang membutuhkan uang karena adanya suatu keperluan mendesak. Gadai menjadi solusi bagi kebutuhan keuangan yang mendesak yang dibutuhkan oleh masyarakat. Sayangnya praktek gadai di masyarakat mengandung unsur riba yang diharamkan oleh Islam, sehingga dibutuhkan adanya teori dan praktek riba yang sesuai dengan syariah Islam. Gadai dalam khazanah Islam disebut dengan rahn, ia adalah menggadaikan suatu barang sebagai jaminan atas transaksi hutang yang dilakukannya. Karena sifatnya adalah akad tabaru’ maka tidak boleh ada manfaat yang diambil oleh murtahin (orang yang menerima gadai). Harta yang digadaikan sendiri adalah tetap menjadi milik dari rahin (penggadai) sehingga tidak boleh digunakan tanpa adanya izin dari pemiliknya. Murtahin diperbolehkan mengambil uang pemeliharaan dari rahin jika harta gadaian tersebut membutuhkan pemeliharaan. Inti  dari akad gadai dalam Islam adalah saling tolong-menolong untuk meringankan beban orang lain.  Kata Kunci: Rahn, Fiqh Islam, Hukum Islam, Islam Indonesia

Valoración del cambio ambiental según los “junqueros” y “leñateros” en el sector sur de la región rioplatense (Argentina)
Authors: Stampella Pablo C. , Doumecq María B. , Vojkovic Matilde , Laborda Luciana
Published: March 2019

Mediante un abordaje etnoecológico, se realizaron 24 entrevistas a informantes calificados de los partidos de Magdalena y Punta Indio, en el litoral rioplatense, con el objetivo de recopilar y evaluar las narrativas de junqueros y leñateros locales respecto del cambio ambiental y su impacto en sus vidas cotidianas. Estas actividades extractivas (obtención de leña y recolección de juncos) fueron muy importantes en esta zona, aunque en la actualidad sufren una merma, sobre todo en la actividad junquera, debido principalmente a dos acontecimientos que marcaron el rumbo de la actividad: derrame de petróleo y cambios en los sistemas productivos. En la actividad leñera se registraron cambios principalmente como producto de la creación de la Reserva de Biosfera “Parque Costero del Sur”, sin embargo, a diferencia de los junqueros, la abundancia del recurso leñatero y la reformulación en las prácticas y estrategias de selección hizo posible la permanencia de la actividad a pesar de los cambios sufridos en el área de estudio. Las actividades ejercidas por los informantes influyeron en las narrativas sobre su valoración del cambio ambiental, dado que se reconocieron pocos cambios en común, principalmente, en relación con el clima y la fauna.

Published: March 2019

The narrow genetic diversity and short market availability of litchi (Litchi chinesis Sonn.) are the main constrains for its cultivation more profitable in Indian sub-continent. Late season litchi cultivars in subtropical and tropical India are prone to fruit cracking and diseases susceptibility. Seven promising selections and four late season commercial cultivars viz; CHES-1, CHES-2, CHES -3, CHL-5. CHL-7, Lal Bombaiya, Late Bedana, Purbi,  Selection -3-7, Selection 8-1 and  Swarna  Roopa were evaluated during 2014-15 at ICAR-RCER Ranchi, based on physico-chemical characters, cracking habit and diseases susceptibility. The results revealed that the cultivars Purbi, Lal Bombaiya and Late Bedana were cracking resistant.  The maximum fruit weight was found in the cultivars Lal Bombaiya (22.0 g ) being comparable with Late Bedana (21.2 g) and CHES-2 (21.0 g). The cultivars Lal Bombaiya and CHES –2 had the highest aril weight of 19.44 g and 17.66 g, respectably. The maximum TSS of 22.2 0B was found in CHES-1 both in Jharkhand and Bihar. Late Bedana cultivar had high sugar acid ratio (73.52) with pomegranate flavor and popular for local market. Litchi fruit borer mainly attacked Lal Bombaiya and CHES-2 at early stage whereas the cultivars Purbi and Swarna Roopa were affected (3-6% bunch) by litchi stink bug (Tessaratoma javanica) at late harvest season. From the present study, it was concluded that CHES-1, Lal Bombaiya, Purbi and Late Bedana were promising late season cultivars for commercial cultivation with effective management of litchi fruit borer and stink bug.

Authors: S. Uma Devi , K. Muthuchelian
Published: March 2019

The rhizosphere region of eight different paddy field areas of Theni district was studied for their physico-chemical analysis of soil and the population density of Azospirillum sp. The study results showed range of values of pH (7.4-7.9), bulk density (1.13g/cm3 -1.60g/cm3), water holding capacity (34.31% - 18.25%), electrical conductivity (1.31 – 1.11), organic carbon (0.93% - 0.71%) . The macronutrient values namely total nitrogen (1.72% - 0.78%), phosphorus content (0.177% - 0.122%) and potassium (1.364% - 1.273%) were observed. Also micronutrients of various paddy fields like Zn (0.9% - 0.5%), Cu (2.3% - 1.7%), Fe (10.9% -8.2%), Mn (6.7% - 5.2%) were recorded, whereas the values of available macronutrients namely nitrogen (295kg/ha - 223kg/ha), phosphorous (89Kg/acre - 49kg/acre), potassium (790kg/acre - 490kg/acre) were noted. The Azospirillum population density was highest in Chinnamanur (192 x105 CFU/g) and lowest in Royyanpatti (91 x105 CFU/g).

Authors: Singh Dinesh , Sharma Anu , Sharma Neeraj
Published: March 2019

The paper deals with plant species richness - diversity relationship along the rising elevation in a semi-disturbed tree line ecotone in upper Bhaderwah, a part of lesser Himalaya. 253 plant species distributed over 170 genera and 62 families were recorded during the intensive field surveys carried during May 2014 to September 2016. These included 11 trees, 29 shrubs and 213 herb species with 247 angiosperms and 6 gymnosperms. Family Asteraceae with 37 species dominated the study area. Maximum richness (179) was observed at sub-alpine zone (Site IV) while the trees (H'=1.74) and shrubs (H'=2.48) revealed maximum diversity at Site III and herbs at Site IV (H'=4.60). The maximum evenness for trees, shrubs and herbs was exhibited by sites III (J'=0.79), V (J'=0.87) and VI (J'=0.94), respectively. The diversity and evenness showed an incremental rise along the rising elevation reaching maxima at the mid elevation with Site-IV being the species rich and Site-VII species deficit, which implies that sub-alpine and alpine forests need effective monitoring and conservation.
Stomatal Index of a few common tree species in the Kishangarh Marble Slurry Dump-yard area, Ajmer (Rajasthan): A case study
Authors: Gahlot Lata , Khanna Vibha
Published: March 2019

The size and number of the stomata present on the foliar epidermis of Tree species is directly influenced by the Suspended Particulate Matter. Marble dust is a very fine powder having approximately 40% particles below 75?m diameter of which approximately 30% are having a size less than 25?m present in the atmosphere. A comparative micro-morphological study of stomatal index of the dominant tree speciesAlbizialebbeck, Azadirachta indica, Callistemon lanceolatus growing in the vicinity of Marble slurry dump-yard, Kishangarh (Ajmer) was done from the month of April 2014 to March 2015.The stomatal index of the lower epidermis of A. indica and A. lebbeck leaves from polluted sites was found to have greater value as compared to that with those of unpolluted site during the months of May to October while in case of the rough, leathery leaves of Callistemon lanceolatus, the stomatal index value in leaves from polluted site was less during these months. This may be attributed to the prevailing winds and weather conditions in the area of study which play a crucial role in the accumulated particulate matter on the phylloplane of the selected tree species viz.A. lebbeck, A. indica,C. lanceolatus.

Cucumber Mosaic Virus (CMV) is most widespread and destructive disease of gherkin (Cucumis anguria L.) Most of the commercial varieties are susceptible to CMV disease. Thus, identification of resistant genotypes for management of CMV disease in gherkin is essential. A total of 179 F3 progenies derived from crosses of resistant and susceptible parent’s viz., Acc.1 (susceptible) x Acc. 50 (resistant), Acc.3 (susceptible) x Acc.50 (resistant), Acc.48 (susceptible) x Acc 50 (resistant) were screened for CMV. Among 179 F3 families, 7 were Immune, 17 were Resistant, 76 were Moderately Resistant, 73 were Moderately Susceptible and 6 were Susceptible. The immune and resistant progenies were further confirmed for their resistance reaction by aphid transmission. Significant difference between the estimates of PDI or F3 progenies mapped into different response classes justified the classification.

Pig rearing on concentrate feed may not be economical because of higher market price of raw materials. The alternative source could be the use of swill feeding. Consequently, the impact of the swill feed on the backfat thickness and body measurements calls for investigation against any other alternative feed.  Hence in the present study, an attempt has been made to compare the body measurements and backfat thickness in fattener piglets which were fed with swill feed (T1) vs. Those fed with chocolate cream waste supplemented with swill feed (T2). The statistical analysis of the data obtained in the present study revealed that there was highly significant (P?0.01) difference between body weight gain and backfat thickness (layer I and II) of both the group of piglets which were taken for trial starting from three months of age till five months of age. However, not significant difference (P?0.05) was noticed for body length and chest girth except in the pigs of 150 days age group. This study indicates that swill feed supplemented with chocolate cream waste could be used to reduce the feed cost since higher weight gain is achieved in a shorter time interval, increasing body measurements and backfat thickness compared to swill feed (T1) group of piglets.

Authors: Ranot Mamata , Sharma Rajesh
Published: March 2019

Pinus gerardiana (Chilgoza) is a small to medium sized evergreen tree yielding a highly valuable edible nut. The present investigations were undertaken to assess the different isozymes in Chilgoza pine. Seven isozymes viz., MDH (Malate dehydrogenase), GDH (Glutamate dehydrogenase), SKDH (Shikimic acid dehydrogenase), 6PGDH (6-Phosphogluconate dehydrogenase), MNR (Menadione reductase), IDH (Isocitrate dehydrogenase) and ADH (Alcohol dehdrogenase) were studied. A total of sixteen gene loci were recorded for seven enzyme systems out of which 6 loci namely MDH- A, 6PGDH- A, SKDH- A, IDH- B, MNR- B and ADH- A were polymorphic whereas the remaining ten gene loci i.e. MDH- B, MDH- C, MDH- D, GDH- A, 6PGDH- B, SKDH- B, IDH- A, MNR- A, MNR- B and ADH- B showed no variation. The percentage of polymorphic loci and average number of alleles per locus are one of the useful criterions for comparing species of populations for genetic diversity.

Authors: Junior Hilton Lopes , Marcucci Maria Cristina
Published: March 2019

A espécie vegetal Eucharis x grandiflora Planch. & Linden é utilizada tradicionalmente para ataques do coração, picadas de mosquito, mordidas de cobra, erupções cutâneas e tratamento da gripe, no entanto encontra-se poucos relatos sobre estudos fitoquímicos e atividade terapêutica em periódicos científicos, podendo ocasionar riscos à saúde dos indivíduos que a utilizam. Este trabalho objetivou-se em avaliar a atividade de captura de radicais livres na espécie vegetal E. x grandiflora pelo método fotocolorimétrico DPPH (2,2-difenil-1-picrilidrazila) e quantificar compostos fenólicos (fenóis totais e flavonoides totais) através de suas concentrações por espectroscopia UV/Visível. Para a realização dos ensaios, o material vegetal (bulbos, flores, folhas, haste floral e raiz) foram secados e submetidos à maceração com diferentes solventes: água (H2O), etanol (CH3CH2OH) e água (H2O) + etanol (CH3CH2OH). Posteriormente foi realizada triagem fitoquímica nos extratos a fim de verificar se os mesmos apresentavam compostos responsáveis por combater radicais livres no organismo. Como resultado, verificou que o extrato produzido a partir das folhas apresentou maior concentração de compostos fenólicos e flavonoides e consequentemente melhor atividade de captura dos radicais livres. O extrato aquoso das folhas (LH) apresentou maior concentração de compostos fenólicos, com valor de 171,4 mg/100g, o extrato etanólico das folhas (LE) apresentou maior concentração de flavonoides, como o valor de 114,6 mg/100g e o extrato hidroetanólico das folhas (LHE) apresentou melhor CE50 (concentração que elimina 50% dos radicais livres) com o valor de 82,34 μg/mL, sendo esta considerada moderada quando comparada com outras espécies vegetais.

We re-examined whether memories of different time scales such as week, day of week, and hour of day are used independently during memory retrieval as has been previously argued (i.e., independence of scales). To overcome the limitations of previous studies, we used experience sampling technology to obtain test stimuli that have higher ecological validity and used pointwise mutual information to directly measure the degree of dependency in a formal way. Participants wore a smartphone around their neck for two weeks, which was equipped with an app that automatically collected time, images, GPS, audio and accelerometry. After a one-week retention interval, participants were presented with an image that was captured during their data collection phase, and were tested on their memory of when the event happened (i.e., week, day of week, and hour). We find that, in contrast to previous arguments, memories of different time scales were not retrieved independently. Moreover, through rendering recurrence plots of the images that the participants collected, we provide evidence the dependency may have originated from the repetitive events that the participants encountered in their daily life.

Authors: Bakce Djaimi
Published: March 2019

Dalam rangka mewujudkan kedaulatan pangan, salah satu upaya yang dapat dilakukan adalah dengan menerapkan kebijakan ekstensifikasi melalui perluasan sawah baru. Tulisan ini bertujuan untuk menginformasikan tentang kendala yang dihadapi dan solusi yang diusulkan dalam menentukan lokasi yang layak dari aspek calon lokasi dan aspek calon petani untuk ilmu pengetahuan lebih lanjut dan pencetakan sawah. Survei investigasi dan desain lapangan cetak sawah dilakukan di 7 kabupaten di Provinsi Riau. Temuan utama yang diperoleh adalah: Pertama, sebagian besar calon lokasi yang tidak layak karena termasuk dalam kawasan hutan, sehingga kebijakan khusus perlu diterapkan mengingat beras merupakan kebutuhan dasar bagi penduduk Indonesia. Kedua, terdapat calon lahan yang memenuhi syarat tergantung pada aspek kesesuaian lahan dan irigasi sehingga perlakuan teknis khusus. Ketiga, terdapat calon petani yang belum pernah berusahatani padi, sehingga untuk berhasil dalam Program Ekstensi Beras, penyuluhan dan pendampingan diperlukan bagi petani dari aspek teknis produksi pertanian dan manajemen, serta manajemen kelompok tani. Keempat, dalam perluasan sawah baru biaya yang telah ditetapkan pada Rp. 16 juta/ ha, sedangkan di lapangan banyak kesulitan yang ditemukan, tergantung pada topografi, lokasi dan kebutuhan infrastruktur yang sedang dibangun. Oleh karena itu ada lokasi yang membutuhkan lebih banyak anggaran karena harus membangun sejumlah infrastruktur seperti pintu permanen atau tanggul sehingga sawah aman dari bahaya banjir atau pasang.
