Published: March 2020

Although the bubble contacting a uniformly superaerophilic surface has caused concern due to its application potential in various engineering equipment, such as mineral flotation, very little is known about the mechanism of how the bubble spreads on a surface with anisotropic superaerophilicity. To unveil this mystery, we experimentally studied the anisotropic behavior of a bubble (2 mm in diameter) spreading on the superaerophilic straight trajectories (SALTs) of different widths (0.5 mm–5 mm) in water using a high-speed shadowgraphy system. The 1–3 bounces mostly happened as the bubble approached the SALTs before its spreading. It is first observed that the bubble would be split into two highly symmetrical sub-bubbles with similar migration velocity in opposite directions during the anisotropic spreading. Two essential mechanisms are found to be responsible for the anisotropic spreading on the narrow SALTs (W ≤ 2 mm with two subregimes) and the wide SALTs (W ≥ 3 mm with four subregimes). Considering the combined effect of the surface tension effect of SALT and Laplace pressure, a novel model has been developed to predict the contact size r(t) as a function of time. The nice agreement between this model and our experiments reconfirms that the surface tension effect and Laplace pressure prevail over the hydrostatic pressure.

Published: March 2020

In the present study, an Ascomycete fungal strain, Lambertella sp., isolated from environmental polluted matrices, was tested for the capacity to reduce the contamination and the toxicity of intermediate and old landfill leachates. Batch tests in flasks, under co-metabolic conditions, were performed with two different old leachates, with suspended and immobilized Lambertella sp. biomass, resulting in a soluble chemical oxygen demand depletion of 70% and 45%, after 13 and 30 days, respectively. An intermediate landfill leachate was treated in lab-scale reactors operating in continuous conditions for three months, inoculated with immobilized Lambertella sp. biomass, in absence of co-substrates. The Lambertella sp. depleted the corresponding total organic carbon by 90.2%. The exploitability of the Lambertella sp. strain was evaluated also in terms of reduction of phyto-, cyto-, and mutagenicity of the different Landfill Leachates at the end of the myco-based treatment, resulting in an efficient depletion of leachate clastogenicity.

This study uses the quantile mapping bias correction (QMBC) method to correct the bias in five regional climate models (RCMs) from the latest output of the Rossby Center Climate Regional Model (RCA4) over Kenya. The outputs were validated using various scalar metrics such as root-mean-square difference (RMSD), mean absolute error (MAE), and mean bias. The study found that the QMBC algorithm demonstrates varying performance among the models in the study domain. The results show that most of the models exhibit reasonable improvement after corrections at seasonal and annual timescales. Specifically, the European Community Earth-System (EC-EARTH) and Commonwealth Scientific and Industrial Research Organization (CSIRO) models depict remarkable improvement as compared to other models. On the contrary, the Institute Pierre Simon Laplace Model CM5A-MR (IPSL-CM5A-MR) model shows little improvement across the rainfall seasons (i.e., March–May (MAM) and October–December (OND)). The projections forced with bias-corrected historical simulations tallied observed values demonstrate satisfactory simulations as compared to the uncorrected RCMs output models. This study has demonstrated that using QMBC on outputs from RCA4 is an important intermediate step to improve climate data before performing any regional impact analysis. The corrected models may be used in projections of drought and flood extreme events over the study area.

Introduction: Polycystic ovary syndrome (STD) is a common endocrine and metabolic disorder that affects significantly the general health of 6-18% of women. Data on metabolic disorders in PCOS is so far still limited and lack of uniformity in terms of race, geographic location, human-origin, age, sample size or lifestyle.
Methodology: A cross-sectional description of 759 cases of reproductive-age women who were diagnosed with PCOS by Rotterdam criteria (391) and non-PCOS (368) visited 3 ART centers in central Vietnam including Hue University Hospital, Hue Central Hospital and Danang Hospital for Women and Children, from June 2016 to June 2017. Inclusion criteria to the control group consisted of infertile women without PCOS, regular menstrual cycle, no ovarian disease (ovary cyst/tumor or endometriosis), without history of ovarian surgery or determined ovarian failure. Clinical characteristics and basic hormonal profile, AMH, lipidemia variables, fasting blood glucose and glucose tolerance testing were performed to evaluate endocrine and metabolic status. Input and process data using SPSS 19.0 software.
Results: The PCOS group had a 1.2-fold increase in overweight BMI (RR=1.20 with 95%CI: 1.02-1.42). The mean of waist circumference and waist / hip ratio was higher than that of control group. Lipidemia dysfunction was observed in 176 cases of PCOS (45%), of which total cholesterol abnormalities accounted for 21.0%, triglycerides 21.5%, LDL-C 25.6% and decreased HDL in 7.9%. Glycemia disturbances occurred in 119 cases (accounting for 30.4%) with abnormal blood glucose 16.4% and abnormal glucose tolerance test after 2 hours was 25.0%. Considering the metabolic factors, 68.8% of PCOS cases have at least one disorder. There is a correlation between metabolic disorders and clinical and endocrine factors: increased WHR with age, body mass index, AMH and prolactin; Total cholesterol associated with BMI and prolactin; Triglycerides related to age; HDL-C decrease is associated with BMI, LH and FSH; Hyperglycemia is associated with BMI.
Conclusions: Endocrine disorders and especially metabolic syndrome are common in the infertile patients with PCOS in Central Vietnam. Appropriate screening strategy, early detection and timely intervention are needed to prevent systemic complications related to metabolic disorders.

Published: March 2020

The generation of stable clones for biomolecule production is a common but lengthy and labor-intensive process. For complex molecules, such as viruses or virus-like particles (VLPs), the timeline becomes even more cumbersome. Thus, in the early stages of development, transient production methods serve as a reasonable alternative to stable clone construction. In this work, an investigation of a polyethylenimine- (PEI-) based transfection method for the transient production of Chikungunya (Chik) VLPs, a vaccine candidate molecule, was undertaken. This effort focuses on tracking cell population responses during transfection, understanding how process changes affect these responses, and monitoring patterns in cell performance over the culture duration. Plasmid labeling and VLP staining were employed to comprehensively track cells via flow cytometry and to draw correlations between plasmid DNA (pDNA) uptake and the resulting VLP expression. The method detected high transfection efficiency (≥97%) in all samples tested and demonstrated the capability to track kinetics of plasmid-cell binding. With varied transfection cell concentrations, the pDNA binding kinetics are altered and saturation binding is observed in the lowest cell concentration sample tested in less than 3 hours of incubation. Interestingly, in all samples, the flow cytometry analysis of relative pDNA amount versus VLP expression staining showed that cells which contained fewer pDNA complexes resulted in the highest levels of VLP stain. Finally, to determine the potential breadth of our observations, we compared daily expression patterns of ChikVLP with a reporter, monomeric GFP molecule. The similarities detected suggest the interpretations presented here to likely be more broadly informative and applicable to PEI-based transient production of additional biological products as well.

Authors: Edward Raja Chellaiah
Published: March 2020

To evaluate the physicochemical characteristics, water samples were collected from thirty-three villages at Dindigul district. From the analysis, pH of the all samples were varying from 6.64 to 8.17. The pH values are within the permissible limit. In Natham taluk, bore wells samples showed extreme (991, 963 and 951 mg L-1) total dissolved solids (TDS) values when compared to maximum permissible TDS is 600 mg L-1. The taste of water comes under poor TDS rating. The highest total hardness (TH) 725 mg L-1 was tested at Silukuvarpatti bore well in Nilakottai taluk. Residual free Chlorine and Iron were not detected in any of the samples. All samples showed Nitrate (NO3-) concentrations were ranged from 0 to 25 mg L-1. The values are less than NO3- desirable limit, that is 45 mg L-1 respectively. Maximum number of samples showed chloride (Cl-) values were higher than Cl- permissible limit (1000 mg L-1) as referenced by BIS. The highest Cl- values were obtained at 2950 and 2000 mg L-1 in Pudukkottai well and Sengulam bore well taken from Reddiyarchatiram and Natham taluks. In regards to fluoride (F-) contamination, thirty-four samples showed < 0.5 ppm F- and rest of fourteen samples viewed <1ppm F-. According to BIS and WHO standard, low concentration of F- below 0.5 ppm may increase the risk of tooth decay.

BASIC AUTHORIAL INTENTIONS AND THEIR IMPLEMENTATION
IN THE PRINTED MEDIA TEXT
Authors: Malysheva Alexandra
Published: March 2020

This article is devoted to the study of the ironic journalistic discourse
used by Andrei Kolesnikov, a special correspondent for the newspaper «Kommersant». The research material includes printed journalist media texts created in the genre of an ironic report, A. Kolesnikov is one of the founders of this genre.
The article considers irony as an obligatory element of many discourses, including journalism, as a way of journalist’s worldview.
The key concept of the undertaken research is the concept of authorial
intention proposed by N.I. Klushina. It is noted that three leading intentions of the main types of media discourse interact in a special way – information (information discourse), persuasion (journalistic discourse), entertainment (entertainment discourse) in the ironic journalistic discourse. The article emphasizes that the ideological dominants of these discourses in the ironic journalistic discourse
interact forming symbiosis of information, worldview ideologies and entertaining, paradoxical facts.
The article identifies and analyzes frequency language means and techniques for creating comic and ironic effects in the modern journalistic media text in general and in the texts by A. Kolesnikov in particular. The author proposes a methodology for studying the representation of intentional categories of interpretation, evaluativeness and tonality in media texts, draws conclusions about the influence and interaction of the basic intentions of media discourse and an ironic journalist’s authorial intentions as an established trend in modern
journalistic discursive practices.

This work analyses the referential process performed by a deaf subject in Brazilian Sign Language (BSL) when facing the anaphoric occurrence in a textual cut from Brazilian Portuguese. Therefore, the methodology implemented hereby has had a qualitative nature. A parallel corpus has been compiled using ELAN (EUDICO–Linguistic Annotator) and following the theories of Corpus Linguistics. From all the referential categories contemplated in BSL, the anaphoric deictic has been the most instrumental strategy for conducting the referential chain of the language, e.g. the construction of the referent at specific points in the signalling space.

Regional Awareness and Regional Identity in Czechia: Case Study of the Bohemian Paradise
Authors: Chromý Pavel , Semian Michal , Kučera Zdeněk
Published: March 2020

Since 1980s, we can observe a changing paradigm within the approaches towards regions which understand and deconstruct the “region” as a social process. Instead of understanding the region as an object or a category, this change transforms the region into a subject of interest for scholars. The study of regions is from now on considered a research topic which requires a holistic understanding of geography, broad interdisciplinary approaches as well as local and historical sensitivity. The paper is using a conceptual understanding of a region based on the combination of territorial, symbolic and institutional configurations. Regional identity that permeates through all of these layers is viewed as one of the most important elements of the very existence of the region and its recognition in the regional system. This paper contributes to the discussion on the importance of regional identity in regional development. The case study of the Bohemian Paradise region proves the significant influence of landscape features on the process of regional identity reproduction.
Gated communities as a symbol of a postmodern city: the case of Prague
Authors: Brabec Tomáš
Published: March 2020

The aim of this article is to present gated communities in Prague in the context of postmodern urbanization. The article focuses on the spatial distribution of gated communities, their social structure and the causes of emergence of these residential objects. The research is based on various scientific methods. The article shows that there is no statistically demonstrable logic behind the spatial distribution of gated communities in Prague. Particularly socially privileged inhabitants and affluent foreigners live in these residential areas. The emergence of gated communities in Prague is linked with various processes of postmodern urbanism (internationalization of capital and labour, social polarization, fragmentation, neoliberalism or postfordism).

Analysis of Cost Overruns in Saudi Arabia Construction Projects: A University Case Study
Authors: Alzara Majed , Kashiwagi Jacob , Kashiwagi Dean , Al-Tassan Abdulrahman
Published: March 2020

Public projects in Saudi Arabia have been experiencing low construction project performance for the past decade. Studies have identified the low-bid delivery method as an important factor in causing such delays. In addition, low bids for contracts have not reflected the actual project cost. A case study was conducted at a university campus in northern Saudi Arabia in which the actual project costs for four projects were examined. The study found that all four projects’ costs were higher than the original bid. In addition, a large survey was conducted of 804 classified contractors and universities representatives who identified change orders as the most common factor causing cost overruns in Saudi Arabia. Previous studies showed that some contractors aim to submit low bids for winning the competition then change orders to reduce their losses. Consequently, low bids also lead to cost overruns. In a comparison using the result of a case study and the results of the Performance Information Procurement System (PIPS), Saudi Arabia’s delivery system was identified as a potential cause of project performance issues.

Room-temperature Pd/Ag direct arylation enabled by a radical pathway
Authors: Mayhugh Amy L , Luscombe Christine K
Published: March 2020

Direct arylation is an appealing method for preparing π-conjugated materials, avoiding the prefunctionalization required for traditional cross-coupling methods. A major effort in organic electronic materials development is improving the environmental and economic impact of production; direct arylation polymerization (DArP) is an effective method to achieve these goals. Room-temperature polymerization would further improve the cost and energy efficiencies required to prepare these materials. Reported herein is new mechanistic work studying the underlying mechanism of room temperature direct arylation between iodobenzene and indole. Results indicate that room-temperature, Pd/Ag-catalyzed direct arylation systems are radical-mediated. This is in contrast to the commonly proposed two-electron mechanisms for direct arylation and appears to extend to other substrates such as benzo[b]thiophene and pentafluorobenzene.
Development of a Revised Performance-Perceptual Test Using Quick Speech in Noise Test Material and Its Norms
Authors: Ou Hua , Wetmore Matthew
Published: March 2020

Background:Two audiometric speech measures have been recognized to have associations with hearing aid use success: the Quick Speech in Noise (QuickSIN) test and the Performance-Perceptual Test (PPT). The PPT involves using the same speech test material (Hearing in Noise Test
[HINT]) twice, to evaluate patients’ objective and subjective speech recognition performance in noise and the discrepancy between the two measures (Performance-Perceptual Discrepancy [PPDIS]). Using the QuickSIN to conduct the PPT (revised-PPT) may provide clinicians two pieces of important
information from one test to help predict hearing aid use success and the need for counseling. Moreover, we could achieve the desired clinical efficiency without purchasing additional test materials.Purpose:This study aimed (1) to evaluate the validity and reliability of using the QuickSIN
speech material to administer the PPT and (2) to establish normative data across listeners with normal hearing (NH) and hearing loss (HL).Research Design:This study used a repeated measures design.Study Sample:Of the total 65 participants between 18 and 88 years of age, 20 (31%)
had NH and 45 (69%) had sensorineural HL, ranging from mild to profound in both ears. Thirty-two of the 45 participants with HL were hearing aid users.Data Collection and Analysis:All participants completed the original PPT using HINT and the revised-PPT using QuickSIN, via sound field.
Generalized linear mixed models were used to compare the performance, perceptual, and PPDIS data between the two test materials across all participants. Normative data for the revised-PPT were established from all participants.Results:Significant main effects for both the test material
and hearing status were found for the performance and perceptual data. All interactions were nonsignificant. There were no significant PPDIS differences between the original PPT and the revised-PPT. Normative values for the revised-PPT were established and comparable to the norms for the original
PPT in the present study. The test‐retest results suggested that the revised-PPT has good reliability. In addition, it appeared that there was a negative association between underestimation of hearing ability and hearing aid use success.Conclusions:It is concluded that the QuickSIN
speech material can replace HINT to measure PPT. The revised-PPT may serve as a useful and efficient clinical tool in any clinics for hearing aid fitting and counseling.
Vestibular Screening in Pediatric Patients with Otitis Media
Authors: Rehagen Sonia Kim , Valente Maureen , Lieu Judith E. C.
Published: March 2020

Background:Otitis media with effusion (OME) is a common cause of vestibular disturbances in children. However, young children often lack the language to express their symptoms, and it is uncommon to screen children for vestibular impairments.Purpose:The purpose of this
study was to develop a screening protocol for children presenting with OME to determine if diagnostic vestibular testing is necessary.Research Design:Children with normal hearing (NH), sensorineural hearing loss (SNHL), and conductive hearing loss (CHL) due to OME participated in a
vestibular screening.Study Sample:There were 30 participants, ages four to eight years, ranging from 48 to 101 months included in the study: 10 with NH, 11 with CHL due to OME, and 9 with SNHL.Data Collection and Analysis:The vestibular screening consists of patient and parent
questionnaires and a functional evaluation. The tests examined coordination, balance, oculomotor function, and nystagmus.Results:Those with CHL were significantly more likely to display abnormal smoothness of pursuit, as measured with observations for rapid tracking, absence of or delayed
saccades, and overshoot, than those with NH or SNHL (p = 0.012). Parents of children with CHL due to OME were more likely to report their child experiencing middle ear pressure than the parents of children with NH or SNHL (p = 0.010). In addition, children with CHL were less
likely to report hearing loss than those with NH or SNHL. Parent and patient report were not found to be reliable indicators of vestibular disturbances.Conclusions:This pilot study suggests that children with CHL due to OME present with more oculomotor abnormalities than their peers
with NH. Further research is necessary to determine validity and reliability of the findings for this present study.

Published: March 2020

Background:The literature presents conflicting reports on the relationship between pure-tone threshold average and speech recognition in noise ability.Purpose:The purpose of this retrospective study and meta-analysis was to determine the effect of stimulus audibility on
the relationship between speech recognition in noise ability and bilateral pure-tone average (BPTA).Research Design:Pure-tone threshold and Hearing in Noise Test (HINT) data from two data sets were evaluated. The HINT data from both data sets were divided into groups with complete and
partial audibility of the HINT stimuli delivered at 65 dBA.Study Sample:Normal and hearing-impaired participants were included in this retrospective study. For data set 1 (n = 215), a relatively weak relationship had been found between HINT thresholds and BPTA. For data set 2 (n = 55),
a relatively strong relationship had been found between HINT thresholds and BPTA. For data set 1, only 10% of the participants had partial audibility of the HINT stimuli. For data set 2, 16% of the participants had partial audibility of the HINT stimuli.Data Collection and Analysis:Pure-tone
thresholds and HINT data were obtained from published and unpublished studies. HINT data were collected in a simulated soundfield environment under headphones using the standard HINT protocol. Statistical analyses included descriptive statistics, correlations, and a two-way analysis of variance
(ANOVA), and multiple regression.Results:A two-way ANOVA followed by post hoc analyses revealed a greater difference between the data sets for the Noise Front thresholds obtained with partial rather than complete audibility of the stimuli. A weak and nonsignificant relationship was
found between BPTA(0.5, 1.0, 2.0, 3.0, 6.0 kHz) versus HINT Noise Front thresholds for complete audibility data (r = 0.060, p = 0.356) and a strong relationship was found for the partial audibility data (r = 0.863, p < 0.001).Conclusions:The
proportion of partial audibility data in a given data set may influence the relative strength of the relationship between BPTA and HINT Noise Front thresholds. This brings into question the convention of using pure-tone average as a predictor of speech recognition in noise ability.

Published: March 2020

Biofilm formation of Pseudomonas aeruginosa makes up a sizeable proportion of hospital-acquired infections, because bacteria in biofilms can resist antibiotic treatment. The extracellular polymeric substance of P. aeruginosa biofilm is an imprecise collection of extracellular polysaccharides, proteins and microbial cells. Rumex dentatus belongs to polygonaceae family. This family can be found in Middle East. The aim of this present study was to assess the effect of various concentrations of methanol extract of Rumex dentatus on biofilm formation of Pseudomonas aeruginosa after 48 h and 72 h. In this experimental study we collected Rumex dentatus from Khoramabad, Iran. The working extracts were 250, 125, 62.5, 31.25, 15.62, 7.81, 3.9, 1.95, 0.97 and 0.48 mg/ml. We used microtiter plate method to grow P. aeruginosa biofilm and assess the antibiofilm activity of plant extract. The composition of methanol extract obtained from Rumex dentatus was studied by gas chromatography. The minimum biofilm inhibitory concentration (MBIC) for P. aeruginosa found to be 250 mg/ml. GC-MS  analyses indicated that these fractions contained a variety of compounds including Bicyclo (3.1.1) heptan- 3 -one, 2, 6, 6- trimethyl,  Bicyclo (3.1.1) heptan, 6, 6- dimethyl and Eucalyptol. There were consequential correlations between antibiofilm activity and the concentration of extracts after 48 and 72 h.

Published: March 2020

The article states that the US is eager to see Ukraine become a stable and democratic state, and that a team of the US Embassy provides assistance for Ukrainian partners. Attention is also attached to the fact that since the Revolution of Dignity, Ukraine has undertaken a range of important steps in the implementation of judicial, defence, and economic reforms.
The US supports legislation on the anti-corruption court, activities of the National Anti-corruption Bureau of Ukraine, and efforts Ukraine exerts to restore economic stability, economic growth, cleaning-up of the banking sector, enhancement of the management of state enterprises in the field of energy, reformation of traffic police, and provision of more resources and powers to cities and localities for a better life of their residents.
The states preserve strong cultural ties between them via education, professional exchange programs, and other initiatives. Despite the progress made, a lot of work is still pending to ensure the victims of Ukraine in the Maidan and in Donbas were not in vain. Corruption is still a zeitgeist challenge, the major obstacle for Ukraine to achieve its Euro-Atlantic aspirations. The US will further support reforms in Ukraine and side with it in the struggle against the Russian aggression. Since the outbreak of crisis, the US and European partners have united to protect the sovereignty and territorial integrity of Ukraine. The sanctions related to the Minsk agreements will be maintained until Russia fully complies with the provisions of the Minsk Accords and leaves Donbas. The sanctions in respect of Crimea will be in force unlil Russia returns the Crimean peninsula to Ukraine. Until all of these critical issues are resolved, it is impossible to forge relations with Russia in a business-as-usual fashion. The US will consistently support Ukraine in the face of the Russian aggression.

Tujuan dari penelitian ini adalah untuk menganalisis lingkungan fisik, lingkungan sekolah dan dukungan sosial keluarga terhadap perilaku anak autis. Lokasi penelitian dilaksanakan di Yayasan Sekolah Pelatihan Terapi Anak Mandiri dan Yayasan Special Kids Pekanbaru. Metode penelitian yang digunakan adalah survey terhadap perilaku anak autis. Hasil dari penelitian ini adalah Lingkungan fisik memberikan pengaruh yang bermakna terhadap perilaku anak autis seperti suara handphone, suara hairdryer dan suara lalu lintas dengan stimulus anak melompat-lompat, berlari-lari tanpa tujuan, suka berteriak dan tidak dapat duduk lama. Serta cahaya diruang gelap dan cahaya matahari juga memberikan pengaruh yang bermakna terhadap perilaku anak autis dengan stimulus anak melompat-lompat dan berjalan tanpa tujuan dan ada pengaruh suara dan cahaya terhadap sebagian besar anak sehingga cenderung berperilaku defisit. Pada lingkungan sekolah memberikan pengaruh yang bermakna terhadap perilaku anak autis, Artinya semakin sering guru sekolah memberikan dukungan dan arahan informatif kepada anak, maka anak semakin dapat berperilaku hiperaktif dengan cara belajar disekolah seperti berolahraga, cara mengucapkan salam kepada teman dan berinteraksi yang baik kepada lingkungan disekitarnya. Kemudian hasil penelitian menunjukan terdapat pengaruh yang bermakna antara dukungan sosial keluarga terhadap perilaku anak autis. Dukungan sosial keluarga yang rendah terhadap perilaku anak yang kebanyakan hiperaktif, sedangkan anak yang kategori defisit hanya sebagian kecil dukungan sosial keluarganya yang tinggi.

The Marriage Law in Indonesia (UUP) is a positive legal rule in building a family. The UUP for example states that the purpose of marriage is to form a happy family, while the obligations of a husband and wife are to love, respect, respect and be loyal. Happiness, love, respect and loyalty are part of the psychological domain that cannot be achieved by merely reading normative juridical rules. Therefore a psychology study is needed to study the UUP. In addition to the psychological aspects, it is also important to study the UUP with a normative approach to see whether the UUP elaborates the normative values ​​of the Qur'an as a source of Islamic teachings. The background of this paper is compiled with the aim of explaining the manifestations of psychological aspects formulated in the UUP so that it can be a reference for implementation in building families and analyzing the normative values ​​of the Qur'an absorbed by the UUP. Therefore this UUP study was conducted with an integrated approach to normative and psychological juridical. This study also aims to develop family law with an integrative juridical psychological approach. The primary data sources used are the book of the Qur'aan by Quraysh Shihab, UUP and the book Motivation and Personality which examines happy psychology by Abraham H. Maslow and Triagular Theori of Love which discusses the theory of love in psychological perspective by Robert. J Steinberg as well as secondary sources related to research. The results of this study indicate that forming a happy family as a marriage goal is in harmony with Q.S. ar-Rum (30): 21. While in a psychological perspective marital happiness can be achieved by a husband and wife can achieve if fulfilled the five basic human needs (hierarchy of needs) in humanistic psychology namely: physiological, security, social, appreciation and self-actualization needs. While husband and wife love is manifested in three aspects, namely attachment, caring and intimacy.
