Published: September 2021

The article analyzes the possibility of processing imported hemp raw materials to obtain household textiles using domestic technologies for processing best fibers. The choice of the carding process is justified as a mechanical effect on the geometric characteristics of hemp. A preliminary visual analysis of samples of hemp fibers, which is imported by a domestic enterprise in order to obtain yarn using a carded spinning system, has been carried out. As a result of the analysis of morphometric characteristics, it was found that the resulting fiber is hemp cottonin. The length and thickness of cottonin vary considerably. Such dimensional characteristics do not allow using it for the manufacture of household yarn. To further break down the complex hemp fibers and reduce their length, a carding process is applied. The study of the effect of the carding process was carried out while implementing five carding cycles on a laboratory fiber mixer, which is an imitation of the carding process on carding equipment in a production environment. After each carding cycle, a card canvas is formed, in which the fibers are evenly mixed and oriented in the longitudinal direction. Sizing of hemp fibers occurs after each carding cycle. According to the dimensional characteristics, staple and modal diagrams of the length distribution and diagrams of the diameter distribution of hemp fibers were constructed. It was found that as a result of the carding process, the average length and thickness of hemp fibers decreased significantly while maintaining the normalized breaking load. But at the same time, the proportion of long fibers remains and a rather high linear density of the fibers remains, which does not allow them to be processed into yarn using a carded spinning system. It is recommended that you continue with the mechanical processing process or use carded hemp fiber to make yarn using the machine’s wool spinning system.

Their drawback can be explained by the high cost and regeneration complexity. That is why the usage of natural sorbents (Tashkiv saponite deposits, Khmelnitsky region). They are able to clean contaminated water from colloidal, molecular and ionic substances. Exploring the specified topic, physicochemical properties of various forms of saponites are studied; the area of their usage is defined. The paste for cleaning contaminated surfaces is developed on their basis. The research results have shown that the most effective method is to use natural saponite. The author of the article advises to conduct preliminary acid activation of clay minerals and modification of its surface multivalent metal salts. Saponite clay granulate is obtained with different time and sintering temperature. Granulation is shown to improve the strength and filtration characteristics of natural sorbents, increasing the filtration rate and the duration of the filter cycle. The influence of the granulation process on the sorption properties of the obtained granulated aluminasilicates is investigated. A detailed hydrocarbon analysis of the A-92 starting gasoline is carried out. The composition of the purified samples of the hydrocarbon mixture is evaluated with gas chromatography using saponite granulate (Octane rating = 94,013 according to the method of research) under static conditions. The structure changes of raw and acid activated saponite clay has been investigated by nitrogen adsorption method and scanning electron microscopy. Established that the porous structure of saponite clay mineral represented by micro-meso porous system with domination of micropores. Acid modification promotes the development of specific surface area (from 47,7 m2/g to 177,9 m2/g) and increase the total volume of pores (from 0,134 cm3/g to 0,201 cm3/g).

Early determination of the thermal lesion degree in case of scald accelerates the treatment process and increases its effectiveness. The thermal lesion degree can be evaluated by determining the temperature difference between healthy and injured areas of biological tissue. For this purpose, a model of biological tissue in the form of a multilayer structure can be used. Heat exchange processes in such a structure are described by a generalized thermal model. Such structure contains conditionally flat heat sources located in each layer, which have the form of a developed network of blood vessels. The considered model of biological tissue quite accurately describes the heat exchange processes in body tissues. The article considers heat exchange processes that take place in biological tissue and a number of assumptions that should be used to mathematically describe these processes were identified. During the analysis of heat transfer process, the equations of temperature distribution in the tissue layers and the boundary conditions that describe the thermal interaction of the model with the environment are determined. As a result, the model of the stationary thermal regime of a biological tissue fragment in the form of a generalized thermal model and a mathematical model of the temperature field distribution in this fragment is obtained. This model is determined by many parameters, which are divided into 3 groups: thermophysical parameters; structural and topological parameters; parameters of the blood vascular system. Models of the particular fragment thermal regime are unequivocally determined by a combination of these parameters. For the analysis of temperature in any point of biological tissue modelled part mathematical model of temperature field distribution in stationary mode was developed. This model allows reasonable approach to the thermal lesion degree evaluation on the basis of the surface temperature difference between healthy and injured areas of tissue.

The article presents the architecture and operation principles of the system for collecting and analyzing information from strain gauges. These systems are used to determine the equipment performance for transporting a variety of materials. In particular, they are used to control the movement of bulk materials mixtures components. For such technological processes, it is fundamentally important to ensure constant flows intensity. The paper identifies three variants of sensor connection schemes, analyzes their advantages and disadvantages. It is established that the structure “one ADC – several sensors” allows to reduce equipment costs and at the same time to provide the minimum parameters influence of a transmission line on a useful sensor signal. The “one-to-one” scheme provides the connection of each sensor to its own ADC. “Circuit with multiplexer” allows to increase the number of sensors connected to one ADC. It is established that the best option in terms of reducing the interference effects on the analog signal and the cost of creating a system is the scheme “one ADC – several sensors”. The algorithm of information transfer from ADC to microcontroller (MC) is analysed. It is calculated that HX711 ADC chips provide the maximum data rate of 18.5 values/s. It is proposed to transfer data between the MC and the server using the TCP protocol because it avoids data loss and provides the necessary data transfer speed. The structure and formats of data that are transmitted from the mass sensor to the ADC, microcontroller, web server and database are proposed. The main speed, design parameters, advantages and disadvantages of wired and wireless data network between MK and the server are determined. Recommendations for the design of such a network depending on the characteristics of the premises in which the data collection system will be used have been developed.
Notes on actionality in two Nguni languages of South Africa
Authors: Crane Thera Marie , Persohn Bastian
Published: September 2021

This paper presents some key findings of studies of actionality and the verbal grammar–lexicon interface in two Nguni Bantu languages of South Africa, Xhosa and Southern Ndebele. We describe interactions between grammatical tense marking (and other sentential bounding elements) and lexical verb types, arguing for the salience of inchoative verbs, which lexically encode a resultant state, and, in particular, a sub-class of inchoative verbs, biphasal verbs, which encode both a resultant state and the “coming-to-be” phase leading up to that state. We further discuss other important features of actional classes in Xhosa and Southern Ndebele, including topics such as the role of participant structure and the relative importance of cross-linguistically prominent distinctions such as that between Vendlerian activities and accomplishments. Although differences between Xhosa and Southern Ndebele are evident both in the behaviour of individual tense-aspect forms and in the interpretive possibilities of specific verbs, the general patterns are quite similar. This similarity suggests that the patterns are likely to extend to other Nguni languages, as well, and that cross-linguistic comparison of particular lexical items across these languages are both feasible and likely to bear fruit.
Tone alternation in Dàgáárè verbs: Perfectives and Imperfectives
Authors: Angsongna Alexander
Published: September 2021

While previous studies on Dàgáárè tone have looked at the nouns, this paper particularly examines tone in verbs, perfective vs imperfective forms. The verbal system has different patterns based on the form of the verb. There are three tone classes for Dàgáárè verbs and for each of the classes, the surface tone pattern it exhibits in the perfective is systematically different from the tone patterns in the imperfective. For the perfectives we have L, H and HL while the imperfectives have LH, HL and H!H, at least in the dialect under study. I treat tone as a combination of the features [±upper] and [±raised] which are connected to what is described as a Tone node (T-node). These Tone nodes in turn connect to the syllable. Under this system, I assume L is represented with the features [-upper] and [-raised] and H with the features [+upper] [+raised]. Underlying tonal melodies of the root morphemes are identical to the surface tones of the perfective forms whether these contain an overt suffix or not. For the imperfectives, the suffix comes with an unspecified underlying T-node. The grammar then chooses the features [±upper] and [±raised] to insert under the already existing T-node.

Published: September 2021

ABSTRACTNowadays, uncontrollable spending habit towards Malaysian young generations are becoming progressively. They have a tendency to have less value of money compared to the elder generations in spending their money. Since the cost of living in Malaysia has improved remarkably, the young generations enjoyed spending their money heavenly, therefore Malaysia faced changes in lifestyle and spending trend. This study proposes to investigate the relationship between money attitude and socio-demographic as determinants of college students’ spending behaviours. As such, the correlation between money attitude factors (power-prestige, distrust, retention-time and anxiety) and spending behaviours among Malaysian college students is a topic worthy of further exploration. At the same time, this study also attempts to explore whether college students’ spending behaviours are affected by their socio-demographic factors such as gender, age. The sample of this study consists of 176 students from three different universities in the Shah Alam area i.e University Selangor (UNISEL), University Management Science (MSU) and Universiti Teknologi Malaysia (UiTM). The regression analysis showed that there were only two factors of money attitude (power-prestige, and anxiety) that had a significant effect on spending behaviour among these universities’ students. However, from the analysis, it can be revealed that none of the socio-demographic factors had a significance (more than 0.05) towards the spending behaviour of the students. Thus, age (positive result) is the most influenced factor of the students’ spending behaviour. Consequently, several suggestions have been put forward and hoped that it will assist students in managing their fund effectively

Published: September 2021

Intracranial epidermoids are rare congenital lesions which account for around 1% of all intracranial tumors. They present most commonly in cerebello-pontine angle followed by suprasellar region, along with different intracranial areas. The most common presentation includes headache, cranial nerve deficiets, seizures, raised intracranial pressure. It is extremely uncommon for epidermoid tumors to present with psychiatric symptoms. We present a case of 38 year old female with history of psychosis for 2 years with personality change, disorganised behavior and delusions. An episode of increased sedation and semi-consciousness led to neuroimaging which revealed a large epidermoid tumor of suprasellar region and interpeduncular region. Surgical resection of the epidermoid was done and patient was maintained on drug treatment.

Published: September 2021

Bone tissue has powerful regenerative properties, thanks to which, with stable fixation, quite large amounts of skeletal bone damage can be successfully repaired. However, in the case of fragmentary fractures, the use of osteosynthesis methods alone does not always ensure the optimal course of reparative regeneration, as its regenerative potential is lost. Therefore, there is a need to replace post-traumatic bone defects and stimulate reparative osteogenesis. For this purpose, doped or doped with various elements (Ge, Si, Zn, Ag, Cu) composite materials. The aim of the study was to investigate the dynamics of hematological parameters in rabbits for osteosubstitution by hydroxyapatite ceramics doped with germanium and in combination with a blood clotting activator. Model defects were formed in the radial diaphysis and femur metaphysis in rabbits with a 3 mm and 4.2 mm diameter drill bit, respectively. Anesthesia included acepromazine, thiopenate, and lidocaine infiltration anesthesia. Animals of the first experimental group (n = 12) were replaced by defects with granules of hydroxyapatite ceramics doped with germanium (HTGe), the second (n = 12) – hydroxyapatite ceramics doped with germanium with blood coagulation activator (HTGe + a), the third – (n = 12). hydroxyapatite α + β with active (α + β + a), and control – granules of undoped ceramics (HT). On day 7, animals of all groups had minor post-traumatic erythrocytopenia and oligochromemia. There was also a gradual increase in the content of leukocytes in the blood with a peak on the 14th day, which in the group HTGe + a lasted until the 30th day. The increase in the number of leukocytes and their peak values occurred within the physiological norm and only approached its upper limit. In most groups there was a pronounced thrombocytosis during the first 14 days with normalization to the 30th day, but in the 2nd experimental group the number of platelets returned to normal only on the 60th day. Changes in most integral hematological indices, which reflect the relationship between blood cell populations, are characteristic of the inflammatory-resorptive phase of reparative osteogenesis. The dynamics of hematological parameters indicates the absence of a pronounced reaction of the body to the implantation of hydroxyapatite composite doped with germanium. The combination of hydroxyapatite ceramics doped with germanium with coagulation activator eliminates post-traumatic oligochromemia and erythrocytopenia and significantly increases the level of hematological integral indices, which indicates a more intensive course of inflammatory-resorptive clinical resorptive aparation phase.

Authors: Zhao Xueqin
Published: September 2021

The porcine intestinal epithelial cell line IPEC-J2 cells, which were isolated from neonatal piglet mid-jejunum, the main components of the intestinal epithelium and play an important role in the intestine. Escherichia coli is an important cause of diarrhea in human and animal. E.coli infections are the leading cause of travelers' diarrhea and a major cause of diarrhea in developing nations, where it can be life-threatening among children. The aim of this study is to explore MPX against E. coli to inhibit IPEC-J2 cells apoptosis and enhance cell barrier. In this study, scanning electron microscopy results found that E. coli infection caused cell apoptosis and destroyed cell membranes of IPEC-J2 cell. MPX effectively alleviated apoptosis of IPEC-J2 cells. The laser confocal results further found that MPX prevented cell apoptosis by inhibiting caspase-3 and caspase-9 activation. In addition, it was found that MPX regulated the expression of tight junction proteins ZO-1, Occludin, and Claudin-1 in IPEC-J2 cells and is closely related to Rac1 by adding a Rac1 inhibitor. The results of adhesion and invasion experiments further found that MPX inhibited bacterial adhesion and invasion through Rac1. The above results indicated that MPX has better function in inhibiting IPEC-J2 cells apoptosis and enhancing cell barrier.

The purpose of this work was to analyze the thermal balance of easily assembled premises of different types and sizes during the periods of low average daily temperatures. The research was conducted during the winter period of 2020–2021 in the Kyiv region. The used material was easily assembled premises of different types and sizes: easily assembled ones without insulation elements; with elements of warming and premises with deep-litter. In each of the studied premises were kept 400 dairy cows. The studies were performed during two periods: the first period had ambient temperatures from -10 to -14.9 °C and the second one from -15.0 °C and below. In our studies, the average daily temperature (during the ambient temperature from -10 to 14.9 °C) in easily assembled premises with the use of insulation elements was 6.20 and 5.31 °C higher than in premises without insulation and deep-litter. A similar trend was observed during the period of lowering the ambient temperature up to 15 °C and below. Thus, the advantage of the premises without insulation constituted 6.28 °C, and of the premises with deep-litter per 5.84 °C, respectively. It was found that keeping in easy-to-assemble premises with insulation elements, the consumption of free thermal energy from the whole herd during the experimental periods was lower compared to the keeping in a boxing cowshed and a cowshed with deep litter. This is due to the smaller range of fluctuations in the average daily temperature in a room with insulation elements. A similar trend was observed for energy consumption through enclosing structures and for moisture evaporation and, accordingly, total heat consumption. In general, heat deficiency was observed during the keeping of cows in the investigated premises of easily assembled type at negative temperatures (-10–14.9 and -15 °С and above). Accordingly, the thermal balance of the premises was negative. The highest values of heat balance among easily assembled premises in both research periods were observed for keeping in rooms that used insulation elements.

Published: September 2021

The aim of the study was to investigate the effect of the feed additive “Butaselmevit-plus” on the state of the antioxidant defense system of piglets during weaning. The experiments were conducted on the basis of the LTD “KOSHET” Mukachevo district of Zakarpattia region. Two groups of piglets were formed – control and experimental, in the amount of 10 individuals in each group, selected on the principle of analogs – age, breed and body weight. Animals were fed according to the norms for this age of pigs. On the 28th day of life, the piglets were weaned from the sow and regrouped from different nests for further maintenance during fattening and rearing with a change in the structure of the diet, which served as technological stress for the animal's body. Piglets of the experimental group, from 21 to 40 days of age, were additionally fed the feed additive “Butaselmevit-plus” at a dose of 100 mg/kg body weight per day. The material for the study was blood, which was taken in the morning before feeding the animals by puncture of the cranial vena cava for 20 days of life (the period before weaning), for 25 days of life (the period before weaning), for 30 days of life (2 days after weaning), for 35 days of life (7 days after weaning), 40 days of life (12 days after weaning). It is proved that feeding piglets feed additive “Butaselmevit-plus” enhanced the antioxidant status of piglets after weaning. It was found that under conditions of technological stress, the use of feed additive “Butaselmevit-plus” in the amount of 100 mg/kg body weight per day improves the antioxidant defense of the body, as evidenced by an increase in blood 35-day-old piglets superoxide dismutase activity by 26.7 % (P < 0.001), catalase – by 39.5 % (P < 0.001), glutathione peroxidase – by 51.7 % (P < 0.05), glutathione reductase – by 52.9 % (P < 0.05), the content of reduced glutathione – at 58.3 % (P < 0.001). These results confirm the effectiveness of the use of milk thistle, methionine, selenium, and vitamins A, E, and D3 in the feed additive “Butaselmevit-plus” to piglets in the period before and after weaning to activate the protective systems of their body.

Published: September 2021

Due to low neutron absorption cross section, high mechanical strength, high thermal conductivity and good corrosion resistance in water and steam, Zirconium alloys are widely used as fuel cladding material in nuclear reactors. During life-time of a reactor the microstructure of this alloy is affected due to, among other factors, radiation damage and hydrogen damage. In this work mechanical properties changes on neutron irradiated Zr-1wt.% Nb at low temperatures (< 100 °C) and low dose (3.5 ´ 1023 n m-2 (E > 1 MeV)) were correlated with hydrides and crystal defects evolution during irradiation. To achieve this propose, tensile tests of: 1) Non-hydrided and non-irradiated material, 2) Hydrided and non-irradiated material and 3) Hydrided and irradiated material were performed at 25 ºC and 300 ºC. Different phases, hydrides and second phase precipitates were characterized by transmission electron microscopy (TEM) techniques. For the hydrided and irradiated material, the ductility decreased sharply with respect to the hydrided and non-irradiated material, among other factors, due to the change in the microstructure produced mainly by neutron irradiation. Even if the presence of the hydride ζ (zeta) was observed, both in the irradiated and non-irradiated material, tensile tests showed that ζ-hydrides did not affect ductility, since hydrided samples are more ductile than non-hydrided samples.

Published: September 2021

Batik is one of Indonesia's original cultural heritage that must be preserved. However, the resulting liquid waste has a negative impact on the environment because it contains high levels of phosphate, surfactant, TSS, TDS, turbidity, BOD5 and COD contaminants. An effective method for dealing with batik waste is electrocoagulation, which is coagulation in the presence of an electric current using electrodes. This study treats batik waste by electrocoagulation using aluminum electrodes, which are operated at a current of 5 Ampere, electrode distance is 2 cm, electrode thickness is 0.1 cm, electrode cross-sectional area is 7x10 cm with a waste volume of 500 mL. The effect of potential difference treatment (3 volts, 4.5 volts, 7.5 volts, 9 volts, and 12 volts) and contact time (15 minutes, 20 minutes, 25 minutes, 30 minutes, and 35 minutes) on changes in COD and TSS levels were studied. Optimal conditions were obtained at a potential difference of 12 volts for 35 minutes with a COD reduction efficiency of 84.84% and 91% for TSS.

Ethanol is a fuel with a high octane number and is environmentally friendly. Bioethanol which can be made from biomass materials such as pineapple peel, is considered not to interfere with food security. With a fairly high carbohydrate and glucose content, pineapple can be converted into reducing sugars that can be fermented to produce ethanol. This study was conducted using the journal review method and aims to determine the mechanism, the variables that play the role, and the optimum conditions of fermentation in the manufacture of bioethanol from pineapple peel. The focus of the analysis was on hydrolysis, namely the type, concentration of the hydrolyzing agent, pH, temperature, and concentration of yeast in fermentation. The analysis from previous studies, the best hydrolysis was obtained by enzymatic hydrolysis using cellulase enzymes with a concentration of 1%-2%. The optimum pH of fermentation was found at pH 5 to pH 6, the fermentation temperature was 30 oC with a Saccharomyces cerevisiae concentration of 1.5% – 2%, and the optimum fermentation time occurred in the range of 48 to 96 hours. The high amount of reducing sugar produces a high amount of ethanol as well.

Introduction. Metacognition is essential for developing clinical thinking skills. Metacognitive skills are widely regarded as important for doctors, but they are rarely formed and evaluated in higher medical school. To solve this problem, it is required to determine how the cognitive, regulatory and reflexive indicators of metacognitive awareness in doctors change throughout their professional life. This work aims to study the metacognitive awareness of doctors at different stages of professional education. Methods. The study involved 1st-year students of the Department of General Medicine (N=48), medical residents (N=44), and doctors enrolled in advanced training cycles (N=34) of the Yaroslavl State Medical University. To study the cognitive, regulatory and reflexive indicators of metacognitive awareness, the following methods were used: "Metacognitive Awareness Inventory" (G. Schraw, R. Dennison, adaptation by E.Yu. Savin, A.E. Fomin), "Assessment of metacognitive knowledge and metacognitive activity" (Yu.V. Poshekhonova, M.M. Kashapov), "Methodology of the level of expression and direction of reflection" (M. Grant). Research results. Significant differences were revealed in metacognitive awareness indicators at the initial and final stages of higher education (U=800.0, p≤0.05). According to the results of the study, it was found that the higher the stage of higher professional education is, the higher is the ability to manage information (U=783.0, p≤0.05), choose the main ideas (U=800.0, p≤0.05) and control errors (U=790.0, p≤0.05). Moreover, indicators of socio-reflection are more pronounced (U=702.5, p≤0.01). The doctors enrolled in further education courses have a high level of metacognition. The significant differences were found in terms of the following indicators: metacognitive knowledge (U=309.5, p≤0.001), metacognitive activity (U=295.5, p≤0.001), concentration (U=417.5, p≤0.001), acquisition of information (U=275.5, p≤0.001), choice of main ideas (U=528.5, p≤0.05), and time management (U=338.0, p≤0.001). There are no significant differences in the reflexive component of the metacognitive awareness of doctors at the stage of additional professional education and the final stage of higher education. Conclusion. All indicators of metacognitive awareness among doctors are formed at the stage of higher education. The reflexive component of metacognitive awareness helps to adapt to the changing conditions of obtaining additional professional education. Metacognitive awareness, with the help of which doctors are aware of their own thoughts and use the best ways to solve problematic situations, allows them to cope with difficulties in the learning process and in professional activity.

Published: September 2021

Com o avanço da tecnologia e o advento da Internet das Coisas surgiram inúmeras possibilidades, as quais permitem o uso de diversos aparelhos via controle remoto ou até mesmo por comando de voz, possibilitando a fácil interação de pessoas com máquinas, graças a Interfaces Homem e Máquina (IHM), podendo oferecer sistemas cada vez mais inteligentes para resolução de problemas do cotidiano. Este trabalho objetiva-se em desenvolver um assistente virtual com comando de voz para auxílio de pessoas com deficiência visual e baixa mobilidade a fim de promover maior praticidade e funcionalidade no ambiente domiciliar, de acordo com as necessidades do deficiente. Trata-se de um estudo de campo prático e qualitativo, com o intuito de desenvolver um assistente virtual para promover praticidade e autonomia as pessoas com deficiência. Foi utilizado o compilador Visual Studio 2017 como plataforma de desenvolvimento do assistente virtual na linguagem C sharp, utilizando a (API) “microsoft Speech.Recognition”. Utilizamos a plataforma de desenvolvimento IDE ARDUINO 2019 para desenvolvimento do software embarcado na placa Arduíno para comunicação entre as placas logicas através da programação. Ao finalizar o desenvolvimento do software encontrou-se algumas dificuldades como o Assistente Virtual realizar comandos que não foram solicitados e o ajuste na sensibilidade do reconhecimento de voz. Após período de teste e implantação, o sistema do Assistente Virtual funcionou da forma desejada, recebendo o comando de voz para ligar o ventilador e o executando, ligando o dispositivo e informando que o ventilador foi ligado para o desenvolvedor. Conclui-se que o Assistente virtual é de extrema importância na autonomia e independência no dia a dia de pessoas com deficiência, facilitando suas atividades de vida diária. Durante o percurso do projeto notou-se que alguns desafios necessitam de ajustes, com por exemplo, a implantação e suas diversidades residenciais e pessoais de cada usuário. Se faz necessário reaver alguns métodos de software, hardware e implantação, para efetividade e inovação, afim de promover uma melhor experiência para o usuário.
Defining 'Housing Developer' and 'Housing Development' under Malaysian Housing Law
Authors: Md Dahlan Nuarrual Hilal , Kamaruddin Abdul Rani
Published: September 2021

The words housing developer and housing development have been defined in section 3 of the Housing Development (Control and Licensing) Act 1966 (the Act). These statutory definitions have severally been discussed and examined by the courts in several case law and it has been contended that the meanings of the definitions are too loose,enigmatic and vague. The certitude on the meaning of housing developer and housing development is a must for otherwise, it would be difficult for the Ministry of Housing and Local Government (MHLG) and as well as to the public to identify persons deemed to be housing developers or carrying out housing development. It is perceived that not all persons, who have literally been called as housing developers, or carrying out housingdevelopments activities fall within the intended legal and statutory definitions of the Act. Thus they are not requiredto abide by the provisions of the Act. Conversely, persons who may have been initially deemed not to have undertakenactivities of housing developer or carrying out housing development, yet based on the principles adopted and defined in section 3 of the Act and the judgments in the case law, have rendered them not to have fallen into the meaning of housing developers and/or carrying out housing development and thus are subject to the provisions and obligations provided in the Act. Again, based on examinations over these definitions, it is found that the definitions of housing developer and housing development as spelt out in section 3 and surprisingly from the principles enunciated in the case law, the meaning of housing developer and housing development are still uncertain and open to various interpretations.
